- In this investigation, we show the presence of both free glutamate (microdialysis) and glutamate NMDAR1 receptors (immunohistochemical analyses of tendon biopsies), in tendons from patients with chronic Achilles tendon pain (Achilles tendinosis) and in controls (pain-free tendons). The NMDAR1 immunoreaction was usually confined to acetylcholinesterase-positive structures, implying that the reaction is present in nerves. Glutamate is a potent pain mediator in the human central nervous system, and in animals it has been shown that peripherally administered glutamate NMDA receptor antagonists diminish the response to formalin-induced nociception. Our present finding of glutamate NMDA receptors in human Achilles tendons might have implications for pain treatment.

- OBJECTIVE: To characterise Achilles tendon structure and thickness a minimum of 8 years after intra-tendinous surgery. Material and METHODS: Fourteen patients (16 tendons; 9 men and 5 women, mean age 43 years, range 27-55) surgically treated (intra-tendinous surgery) for chronic painful midportion Achilles tendinosis, were followed with clinical examination and grey-scale ultrasonography for a minimum of 8 years (range 8-16 years, mean 13 years). RESULTS: All patients were satisfied with the result of surgery and were active in Achilles tendon loading activities without restrictions. In all operated tendons, structural abnormalities remained and tendons remained thicker than normal tendons. CONCLUSIONS: Resection of tendinosis is associated with persistent structural abnormalities and thickening of the tendon 13 years after surgery, despite successful clinical outcomes.

- While Roux-en-Y gastric bypass (RYGB) surgery in obese individuals typically improves glycemic control and prevents diabetes, it also frequently causes asymptomatic hypoglycemia. Previous work showed attenuated counterregulatory responses following RYGB. The underlying mechanisms as well as the clinical consequences are unclear. In this study, 11 subjects without diabetes with severe obesity were investigated pre- and post-RYGB during hyperinsulinemic normo-hypoglycemic clamps. Assessments were made of hormones, cognitive function, cerebral blood flow by arterial spin labeling, brain glucose metabolism by F-18-fluorodeoxyglucose (FDG) positron emission tomography, and activation of brain networks by functional MRI. Post- versus presurgery, we found a general increase of cerebral blood flow but a decrease of total brain FDG uptake during normoglycemia. During hypoglycemia, there was a marked increase in total brain FDG uptake, and this was similar for post- and presurgery, whereas hypothalamic FDG uptake was reduced during hypoglycemia. During hypoglycemia, attenuated responses of counterregulatory hormones and improvements in cognitive function were seen postsurgery. In early hypoglycemia, there was increased activation post- versus presurgery of neural networks in brain regions implicated in glucose regulation, such as the thalamus and hypothalamus. The results suggest adaptive responses of the brain that contribute to lowering of glycemia following RYGB, and the underlying mechanisms should be further elucidated.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: We aimed to explore learning experiences among medical students learning to perform pelvic examinations and to identify factors that facilitate their training.Methods: A mixed-methods study including a web-based survey and focus group discussions (FGDs) was conducted among medical students who had completed their obstetrics and gynaecology (ObGyn) clerkship. The FGDs were recorded, transcribed and analysed using qualitative content analysis with systematic text condensation. Survey factors were compared using the χ2 test or Fisher's exact test.Results: 160 students (97 female, 61 male, two other) at six universities in Sweden responded to the survey. Two mixed FGDs were conducted. The majority (87%) of the students experienced confidence in performing pelvic examinations, stating that sufficient, repeated training opportunities and support from a clinical tutor were crucial components of the learning experience. Prior to the ObGyn clerkship, negative expectations were more common among male students. The male participants experienced having a disadvantage because of their gender, while female students considered their gender an advantage (p<0.001, N=121, Fisher's Exact Test). The clinical tutor and the use of professional patients (PPs) had a fundamental role in providing learning opportunities by including the student in patient care activities.Conclusions: The importance of the clinical tutor, as well as the use of PPs, are important factors when planning education in pelvic examinations, and this knowledge could be used when educating other intimate examinations during medical school. In addition, similar investigations on students' experience in training other intimate examinations could be considered.

Near infrared spectroscopy for assessing oxygenation and hemodynamics in the upper extremities of healthy subjects and patients with work-related muscle pain
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The prevalence of work-related muscle pain (WRMP) is large in the general population in the industrialized world. Despite significant advances over recent years in some research areas, the mechanisms of why WRMP occurs and the pathophysiological mechanisms behind the disorders are still unclear. One suggested explanation is that WRMP is caused initially by a limitation of the local muscle circulation and oxidative metabolism. There is a lack of objective methods to gauge the development and diagnosis of WRMP. Near infrared spectroscopy (NIRS) is a non-invasive technique that allows for determinations of oxygenation and blood flow. The purpose of this thesis was to evaluate NIRS (1) as a method for measuring muscle oxygenation and hemodynamics for the extensor carpi radialis (ECR) and trapezius descendens muscles (TD), and (2) to investigate whether variables measured by NIRS differed between patients diagnosed with WRMP and healthy subjects. Several variables of NIRS were produced and investigated. These included muscle oxygenation (StO2%), changes during contractions (∆StO2%) and StO2% recovery (Rslope), total hemoglobin (HbT) as an indication of blood volume and its changes during contractions (∆HbT). In addition, for the ECR, by applying an upper arm venous occlusion (VO) HbTslope increase as a surrogate of blood flow, and for both VO and arterial occlusion (AO) HHbslope increase (i.e. deoxyhemoglobin slope) as a surrogate of oxygen consumption were variables of interest. A first objective was to determine how StO2% and HbT responded to various contraction forces and how it related to muscle activation measured by electromyography (EMG). For both muscles isometric contractions of 10, 30, 50 and 70% of maximal voluntary contraction (MVC) were maintained for 20 s each by healthy males and females; additionally a 10% MVC contraction was sustained for 5 min. For the different contraction levels, predictable relationships were seen between ∆StO2% and force, and between ∆StO2% and EMG RMS amplitude. The general trend was a decrease in ∆StO2% with increasing force and increasing EMG. Females showed a tendency for a higher oxygen use (i.e., drop in StO2%) for the ECR over force levels than males and a higher RMS% MVC for the TD. For the 10% MVC contraction sustained for 5 min gender specific changes over time for HbT and RMS for the ECR, and for StO2% for the TD muscle were seen. A second objective was to determine the day-to-day reliability of NIRS variables for the ECR and TD muscles at group level (Pooled data) and at gender level (males and females). Measurements were performed on two occasions separated by 4-6 days and intraclass correlation coefficients (ICC) and limits of agreement (LOA) were determined as reliability and reproducibility indicators, respectively. Variables tested were ∆StO2% during submaximal isometric contractions of 10, 30, 50 and 70% MVC and StO2% recovery (Rslope) after contractions and after AO. For the ECR, HbTslope as an indication of blood flow (using VO) and HHbslope as a surrogate of oxygen consumption for both VO and AO were computed. For ∆StO2% for the ECR the highest ICC was at 30% MVC for both the pooled data and at gender level. For the TD ICCs were comparably high for 30, 50, 70 % MVC (for both muscles the ∆StO2% at 10% MVC showed the lowest ICC). Further, females showed a higher ICC than males for contraction levels of 50 and 70% MVC. For both muscles, LOA for ∆StO2% was lowest at 10% and highest at 50 and 70% MVC. For the ECR Rslope ICCs were high for all contraction levels, but was lower for AO; LOA was lowest at 70% MVC. For the TD, Rslope ICCs were also high for all contraction levels and LOA was lowest at 30 % MVC. ICC for HbTslope was the lowest of all variables tested. For HHbslope ICC was higher for AO than for VO, and LOA was lower for AO. A third objective was to determine if there were differences between healthy subjects and patients diagnosed with WRMP in ∆StO2% and ∆HbT responses during varying submaximal contractions (10, 30, 50 and 70% MVC), and StO2% recovery (Rslope) immediately after contractions and AO. Additional variables tested in the ECR at rest were HHbslope to indicate oxygen consumption (using AO) and HbTslope as an indication of blood flow. There were no differences between groups in ∆StO2% and ∆HbT variables during the contractions or Rslope in the recovery after contractions or AO. Furthermore, HbTslope was not different between groups However, oxygen consumption for the ECR and StO2% for the TD at rest were significantly greater for healthy subjects compared to patients. A fourth objective was to determine if there were differences in StO2% and HbT between healthy subjects and WRMP patients during a 12 min sustained contraction of 15 % MVC. In addition, the protocol included a recovery period of 30 min. Prior to contraction, as well as during the recovery period, HbTslope as a surrogate of blood flow was determined for the ECR. Neither the ECR nor the TD exhibited significant differences between groups for StO2% and HbT during the contraction. For the TD patients showed a lower StO2% value at rest and throughout the contraction than healthy subjects. For the ECR HbT during the sustained contraction the general trend was an initial decrease with gradual increase throughout the contraction for both groups. For HbTslope no differences were seen between patients and healthy subjects before the sustained contraction and during the recovery period for both muscles.NIRS is deemed a suitable technique for assessing physiological measurements of the upper extremity, including for day-to-day testing.NIRS was not able to distinguish between the patients with WRMP and controls. A concern in the thesis is the characteristics of the patient group in being equally active in recreational sports, actively working, and similar in muscle strength as controls. Thus, applying NIRS for studying a more severe patient group could yield different results.

No differences in oxygenation in the forearm and shoulder of patients with work-related muscle pain and healthy subjects during a low-load sustained contraction
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- A frequently ascribed symptom associated to work-related muscle pain (WRMP) is muscle fatigue. Studies investigating oxygenation and hemodynamics in association to fatigue development in the muscles of patients with WRMP are sparse. Inadequate oxygen consumption and/or inadequate blood supply can influence the ability of the muscles to withstand fatigue. In this study we applied near-infrared spectroscopy (NIRS) and electromyography (EMG) to investigate oxygenation, hemodynamics and muscle activity in the extensor carpi radialis (ECR) and trapezius (TD) muscles of patients with WRMP and healthy controls. Eighteen patients with diffuse neck-shoulder-arm pain and 17 controls (matched in age and sex) were equipped with NIRS and EMG probes. After determination of maximal voluntary contraction (MVC) a sustained contraction of 15% MVC was performed with a cutoff for the maximum time of 12 min. Variables generated were StO2% and HbT from NIRS and RMS%max and MPF from EMG during the contraction. T tests and Mann-Whitney tests were used for analyzes of differences in MVC and endurance times. Full factorial repeated measures analyses of variance (ANOVA) were used to assess differences between patients and controls in NIRS and EMG parameters over time. Results showed no differences in MVC between patients and controls. We found, however, a shorter endurance time for patients compared to controls. There were no significant differences in StO2%, HbT, RMS and MPF responses during contraction between groups for the ECR. For the TD there was a group effect for StO2% with patients showing a lower level at rest and throughout the contraction. For the ECR and TD oxygenation, hemodynamics, RMS and MPF there were no straightforward differences between patients and controls that could explain the differences in endurance time. Therefore, we conclude that the shorter endurance time seen in the present study was not measurable by physiological indicators investigated in this group of patients.

Tidskriftsartikel (refereegranskat)abstract
- We tested hypotheses of (i) reduced oxygen usage, oxygen recovery, blood flow and oxygen consumption; and (ii) increased muscle activity for patients diagnosed with work related muscle pain in comparison to healthy controls. Oxygenation was measured with near infrared spectroscopy (NIRS), and muscle activity with EMG for the extensor carpi radialis (ECR) and trapezius descendens (TD) muscles. Eighteen patients with diffuse neck-shoulder-arm pain and seventeen controls (matched in age and sex) were equipped with NIRS and EMG probes. After determining an individual’s maximum voluntary contraction (MVC) force, short term (20 sec) isometric contractions for the ECR and TD of 10%, 30%, 50% and 70% MVC generated ∆StO2% and StO2% recovery (Rslope) from NIRS, and RMS%max from EMG signals. In addition, upper arm venous (VO) and arterial (AO) occlusions generated slopes of total hemoglobin (HbTslope) and deoxyhemoglobin (HHbslope) for the resting ECR as surrogates of blood flow and oxygen consumption, respectively. Mixed Model analyses, t-tests, and Mann-Whitney test were used to assess differences between groups. There was no significant difference in MVC between groups for either muscle. Also, ∆StO2%, Rslope for either muscle, and ECR-HbTslope were not different between groups, thus our hypotheses of reduced oxygen use, recovery, and blood flow for patients were not confirmed. However, patients had a significantly lower ECR-HHbslope confirming our hypothesis of reduced consumption. Further, there was no difference in RMS%max during contractions meaning that the hypothesis of increased activity for patients was not confirmed. When taking into account the number of NIRS variables studied, differences we found between our patient group and healthy controls (i.e. in forearm oxygen consumption and shoulder oxygen saturation level) may be considered modest. Overall our findings may have been impacted by the fact that our patients and controls were similar in muscle strength, which is in contrast to previous studies.

Structures beyond the frameworks of the rink : On organization in Swedish ice hockey
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This is a dissertation on organization in Swedish ice hockey based on four articles. The purpose of the thesis is to contribute knowledge on the direction, management and practice of sport using Swedish elite ice hockey as an example. Knowledge is created by examining four separate but mutually contingent aspects of organizations. Article I contributes to the overall purpose with knowledge on the professionalization of Swedish ice hockey, the reasons behind and the consequences of it. Focusing on the timeframe 1967-2000 the article highlights how norms, values and ideals changed over time and contributed to a change from ice hockey as an amateur sport based on idealistic motives and volunteer efforts to a professional sport based on entertainment and commercial forces. Article II contributes knowledge on the structural organization of Swedish elite ice hockey clubs and contributing factors. The article compares eleven elite ice hockey clubs and shows how they vary in relation to each other from low to high specialization, standardization and centralization but also how they present many similar characteristics such as organizational form, subsidiary businesses, cooperation with farm clubs and upper secondary schools, types of employments and division of workload. Article III contributes with knowledge on how organizational structures are experienced by individuals working or volunteering in the clubs. Comparing experiences in two structurally different clubs, the article shows how more developed structures are experienced more positively than less developed structures are. However, both groups agree that more developed structures are desirable and they also have similar opinions on issues concerning formal education and training, the elite program vs. the youth program, strategic vs. operative tasks and personal freedom. Article IV contributes knowledge on how experiences of mentioned structures are affected by remuneration, authority and centrality. Exploring four positions differing from each other with regard to hierarchical position, distance to the club’s core activities and payment, the article shows that individual experiences of organizational structure vary depending on where in the club the individual works. This variation is shown to result in tensions between the different positions. The knowledge offered in the thesis is based on three data collections. Data have been gathered from official and unofficial documentation from and on the Swedish sports confederation, the Swedish ice hockey association and 11 clubs represented in the highest division 2000/2001, and from individuals working or volunteering in these clubs as board members, general managers, marketing assistants, coaches, volunteers in the youth programs and arena personnel. The studies are carried out within an institutional theory framework and the analysis of the results taken together shows how the structures in elite ice hockey clubs are affected by surrounding environment and societal environments. Norms and ideals concerning legitimate ways of organizing are mediated by authorities, educational establishments, trade organizations and successful models in neighbouring industries. These norms and ideals have changed as new actors such as television networks, commercial sponsors and employed staff have entered ice hockey and as the roles of the government, the associations, the coaches and the players have changed. These ongoing changes are combining to a new context and new circumstances for the direction, management and practice of Swedish ice hockey.

Tidskriftsartikel (refereegranskat)abstract
- All patients with badminton-related acute Achilles tendon ruptures registered during 1990 to 1994 at the University Hospital of Umeå were retrospectively followed up using a questionnaire. Thirty-one patients (mean age, 36.0 years), 27 men and 4 women, were included. Thirty patients (97%) described themselves as recreational players or beginners. The majority of the injuries (29 of 31, 94%) happened at the middle or end of the planned game. Previous local symptoms had been noticed by five patients (16%). Long-term results showed that patients treated with surgery had a significantly shorter sick leave absence than patients treated without surgery (50 versus 75 days). There was no obvious selection favoring any treatment modality. None of the surgically treated patients had reruptures, but two reruptures occurred in the nonsurgically treated group. There seemed to be fewer remaining symptoms and a higher sports activity level after the injury in the surgically treated group. Our results indicate that local muscle fatigue may interfere with strength and coordination. Preventive measures such as specific treatment of minor injuries and adequate training of strength, endurance, and coordination are important. Our findings also indicate that surgical treatment and careful postoperative rehabilitation is of great importance among badminton players of any age or sports level with Achilles tendon rupture.

- During 1990-1994, 1.2% of all sports injuries that required emergency care at the University Hospital of Umeå were caused by badminton. In 90.7% of the cases the patients described themselves as recreational players or beginners. There were 51.3% minor injuries (AIS 1) and 48.7% moderate injuries (AIS 2). The lower extremities were affected in 92.3% of the cases. Achilles tendon ruptures (34.6%) and ankle sprains and fractures (29.5%) were the most frequent. By the time of the follow-up (10-69 months), 52.6% of the players still had symptoms from the injuries and 39.5% had not been able to return to playing badminton. Our data indicate the importance of adequate treatment and rehabilitation after acute badminton injuries.

Tidskriftsartikel (refereegranskat)abstract
- Injuries involving the Achilles tendon and manifested as chronic tendon pain are common, especially among recreational athletes. In a pilot study on a small group of patients with chronic painful midportion Achilles tendinosis, eccentric calf-muscle training was shown to give good clinical results. The aim of this prospective study was to investigate if the previously achieved good clinical results could be reproduced in a larger group of patients, and also to investigate the effects of eccentric calf-muscle training in patients with chronic insertional Achilles tendon pain. Seventy-eight consecutive patients, having chronic painful Achilles tendinosis at the mid-portion (2–6 cm level) in a total of 101 tendons (55 unilateral and 23 bilateral), and thirty consecutive patients with chronic insertional Achilles tendon pain in 31 tendons (29 unilateral and one bilateral) were treated with eccentric calf-muscle training for 12 weeks. Most patients were recreational athletes. Evaluation of the amount of tendon pain during activity was recorded on a visual analogue scale (VAS), before and after treatment. In 90 of the 101 Achilles tendons (89%) with chronic painful mid-portion Achilles tendinosis, treatment was satisfactory and the patients were back on their reinjury activity level after the 12-week training regimen. In these patients, the amount of pain during activity, registered on the VAS-scale (mean±SD), decreased ignificantly from 66.8±19.4 to 10.2±13.7. On the contrary, in only ten of the tendons (32%) with chronic insertional Achilles tendon pain was treatment satisfactory, with a significant decrease on the VAS-scale (mean±SD), from 68.3±7.0 to 13.3±13.2. Our conclusion is that treatment with eccentric calf-muscle training produced good clinical results in patients with chronic painful mid-portion Achilles tendinosis, but not in patients withchronic insertional Achilles tendon pain.

Tidskriftsartikel (refereegranskat)abstract
- Overuse injuries are the most frequent type in badminton, generally localized in the legs. An earlier study found 32% of young Swedish elite badminton players to have experienced disabling pain in the Achilles tendon region during the previous 5 years. The present investigation examined the prevalence and characteristics of painful conditions in the Achilles tendon region in 32 middle-aged competitive badminton players by means of questionnaire and physiotherapist's examination. Pain in the Achilles tendon region was reported by 44%, either presently or during the past 5 years, generally localized in the middle portion of the tendon. Symptoms had lasted 2 weeks-1 year (96 days). On the competition days 22% of the reported pain currently in the region. Age was found to be correlated to Achilles tendon pain, but there was no relationship between symptoms of pain and body mass index, gender, training quantity, or years of playing badminton. In conclusion, Achilles tendon pain seems to be relatively common among Swedish middle-aged competitive badminton players, particularly in the older ones.

- The purpose of this study was to investigate the prevalence and characteristics of painful conditions in the Achilles tendon region in elite badminton players. The study group consisted of 66 players in the Swedish elite division (highest level) in badminton, 41 men (mean age, 24.4 years) and 25 women (mean age, 21.9 years). Twenty-one players (32%) reported the occurrence of a disabling painful condition in the Achilles tendon region during the previous 5 years, and 11 players (17%) had an ongoing painful condition. A majority of the painful conditions (12 of 21, or 57%) were described as involving the midportion of the Achilles tendon. The players who had a painful condition reported a significantly higher weekly training load as measured by the number of hours spent in total training, badminton training, and endurance and strength training. There were no differences in age, sex, and body mass index between the players with and without painful conditions in the Achilles tendon region.

- OBJECTIVE: In this study, structure, blood flow and thickness in the Achilles tendon related to tendon-loading activity were investigated. DESIGN: Examination by ultrasound (US) and colour Doppler (CD) immediately before and after 1 h of floor-ball matchplay. SETTING: Sports Medicine Unit, Umeå University, Sweden. PARTICIPANTS: 36 Achilles tendons in 18 middle-aged (mean 39 years) recreational male floor-ball players. MAIN OUTCOME MEASUREMENTS: Structure and high blood flow (HBF)/neovessels (NV) in the tendons were registered. Tendon thickness was measured 3 and 4.5 cm above the upper calcaneus and at the thickest part of the tendon. RESULTS: The US examination showed that 11/36 tendons (30.5%) in nine individuals had structural changes before and after the floor-ball match. In 7/36 tendons (five with structural changes), there were HBF/NV before, and after, the match. In six of these seven tendons, the blood flow was higher after than before the match. In three more tendons (two with structural changes), there were HBF/NV after, but not before, the match. After the match, mean tendon thickness had decreased significantly in both normal tendons and tendons with structural changes at the 3-cm level (6.0 (1.0) mm to 5.8 (0.9) mm; p<0.019), at the 4.5-cm level (5.7 (1.1) mm to 5.5 (1.0) mm; p<0.044), and at the thickest part (6.6 (1.1) mm to 6.3 (1.2) mm; p<0.000). CONCLUSIONS: In about 1/3 of the tendons, there were structural changes, about half of those tendons also had HBF/NV, which was higher after, than before, the match. Mean tendon thickness in both normal tendons and tendons with structural changes had decreased significantly after a 1-h floor-ball match.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To survey the incidence of clinical risk markers and its correlation with established clinical measurements for cardiovascular disease (CVD) in a heterogeneous spinal cord injured (SCI) patient population.Design: Descriptive, cross-sectional study.Subjects: 78 patients with SCI, at different injury and functional level.Methods: Anthropometric data, blood pressure, a blood lipid panel, blood glucose and a questionnaire were analyzed.Results: Eighty-one percent of all patients had dyslipidemia (DL) and a majority of the patients with abdominal measures below the recommended cut-off levels had DL. Self-reported physical activity above the cut-off level was reported by 32.1%of the patients. There were no differences in clinical measures, serum lipid values and blood glucose between physically active and not active patients. No differences were seen between men/women, tetraplegia/paraplegia and wheelchair dependent/not wheelchair dependent patients.Conclusion: DL is common and seems to be not treated or undertreated in the studied SCI patient group with different neurological lesion and functional levels. General anthropometric clinical measures do not seem to be valid for evaluating risk for CVD in this patient group.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To assess the prevalence of pain, anxiety and depression in a sample of chronic SCI patients in Northern Sweden.Design: Descriptive, cross-sectional study.Setting: Specialist Clinic at a University Hospital.Participants: 78 patients with chronic spinal cord injury, at different injury and functional level.Outcome measures: Patients registered presented pain above, at or below injury level on a Visual Analogue Scale (VAS). Patients currently on pain medication were also registered as having pain. Depression and anxiety were assessed by the Hospital Anxiety and Depression Rating Scale (HADS).Results: Out of 78 patients, 58 (74%) indicated current presence of pain or were on continuous pain medication. Pain above injury level was present in 32% of the patients, with a mean VAS of 15.9±20.1, range 0-60mm. Pain at injury level were present in 24% of the patients, mean VAS 11.0±17.0, range 0-50mm and 58% had pain below injury level with a mean VAS 31.4±22.3, range 0-80mm.Clinically significant psychological disorders were reported in 4 patients (5%) for both anxiety and depression.Conclusions: Pain is very common in persons with chronic SCI, but, at least in a drug-treated population, the pain is at a mild or moderate level. Anxiety and depression were found much less common than reported in other studies. Medication effects have been considered. Even in a presumably well-medicated and well-rehabilitated population, there is still a need for further optimization of pain management, including both pharmacological and non-pharmacological methods.Keywords: Tetraplegia; Paraplegia; Psychological Disorders; Visual Analogue Scale; Hospital Anxiety and Depression Scale

- Objective:To examine whether self-reported physical activity of a moderate/vigorous intensity influences risk markers for cardiovascular disease in persons with paraplegia due to spinal cord injury.Design:Descriptive, cross-sectional study.Subjects:A total of 134 wheelchair-dependent individuals (103 men, 31 women) with chronic (>= 1 year) post-traumatic spinal cord injury with paraplegia.Methods:Cardiovascular disease markers (hypertension, blood glucose and a blood lipid panel) were analysed and related to physical activity.Results:One out of 5 persons reported undertaking physical activity >= 30 min/day. Persons who were physically active >= 30 min/day were significantly younger than inactive persons. Systolic and diastolic blood pressures were lower in the physically active group. When adjusting for age, the association between systolic blood pressure and physical activity disappeared. Physical activity >= 30 min/day had a tendency to positively influence body mass index and low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio. Men had significantly higher systolic and diastolic blood pressures than women, lower high-density lipoprotein cholesterol, higher low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio and higher triglycerides. No other significant differences between men and women were found.Conclusion:Self-reported physical activity >= 30 min/day in persons with spinal cord injury positively influenced diastolic blood pressure. No other reductions in cardiovascular disease risk markers were seen after controlling for age. These results indicate a positive effect of physical activity, but it cannot be concluded that recommendations about physical activity in cardiovascular disease prevention for the general population apply to wheelchair-dependent persons with spinal cord injury.

Spinal cord injuries in Sweden : studies on clinical follow-ups
- 2016

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- A spinal cord injury is a serious medical condition, often caused by a physical trauma. An injury to the spinal cord affects the neurotransmission between the brain and spinal cord segments below the level of injury. The SCI causes a loss of motor function, sensory function and autonomic regulation of the body, temporary or permanent. Significantly improved acute care, primary comprehensive rehabilitation and life-long structured follow-up has led to persons with spinal cord injury (SCI) living longer than ever before. However, increased long-time survival has allowed secondary conditions to emerge, like diabetes mellitus and where cardiovascular disease (CVD) now is the most common cause of death among SCI patients. Other possible CVD-related comorbidities in this patient group have been reported to be pain and mood disturbances. There is still lack of, and need for more knowledge in the field of CVD-related screening and prevention after SCI.The overall aim of this thesis was to contribute to a scientific ground regarding the need for CVD-related screening and prevention after SCI.In Paper I and Paper II, patients with wheelchair-dependent post-traumatic SCI (paraplegia) were assessed. The results in paper I showed that 80% of the examined patients had at least one cardiovascular disease risk marker irrespective of body mass index (BMI). Dyslipidemia was common for both men and women at all BMI categories. The study also showed a high prevalence of hypertension, especially in men. Paper II showed a low frequency of self-reported physical activity, where only one out of 5 persons reported undertaking physical activity >30 min/day. The physically active had lower diastolic blood pressure but no significant difference in blood lipids.In paper III and IV, patients with SCI (tetraplegia and paraplegia) participated in the studies. Eighty-one percent of the patients had dyslipidemia, where also a majority of the patients with normal abdominal clinical measures had dyslipidemia. Self-reported physical activity >30min/day was reported by one third of the patients. No differences were found between physically active and not physically active patients when it came to blood glucose, serum lipid values and clinical measures (paper III). Pain was common in the patient group, however, most often on a mild to moderate level. Anxiety and depression was less common than reported in other studies (paper IV).

- Both physical as well as mental demands result in an increased activity in the sympathetic nervous system (SNS) with changes in blood-pressure and heart-rate. Through local release of catecholamines, e.g. noradrenaline (NAd) SNS exerts various actions at the muscle level. The aims of this study were to investigate the effects of low-load repetitive work alone and in combination with mental demands on local muscle interstitial noradrenaline concentration [NAd]i, muscle activity and oxygenation, assessed with microdialysis, surface electromyography, and near-infrared spectroscopy, respectively. Healthy females (n = 15) were exposed to (1) 30 min repetitive work (RW) and (2) 30 min repetitive work with superimposed mental load (RWML) on two different occasions. Muscle [NAd]i and muscle activity increased significantly in response to RW, but did not increase further during RWML. For RW, [NAd]i was found to be inversely correlated to muscle activity. Oxygenation decreased significantly during work, independently of occasion. Our findings indicate that low-load work causes significantly increased trapezius muscle [NAd]i in healthy females, and short periods of superimposed mental load do not add to this increase and further, that both muscle activity and oxygenation were unaffected by the superimposed mental load.

- Epidemiological research provides strong evidence for a link between repetitive work (RW) and the development of chronic trapezius myalgia (TM). The aims were to further elucidate if an accumulation of sensitising substances or impaired oxygenation is evident in painful muscles during RW. Females with TM (n=14) were studied during rest, 30 min RW and 60 min recovery. Microdialysate samples were obtained to determine changes in [glutamate], [PGE2], [lactate], and [pyruvate] relative to work. Muscle oxygenation (%StO2) was assessed using near-infrared spectroscopy. During work all investigated substances, except PGE2, increased significantly: [glutamate] (54%, P<0.0001), [lactate] (26%, P<0.005), [pyruvate] (19%, P<0.0001), while the %StO2 decreased (P<0.05). During recovery [PGE2] decreased (P<0.005), [lactate] remained increased (P<0.001), [pyruvate] increased progressively (P<0.0001), and %StO2 had returned to baseline. Changes in substance concentrations and oxygenation in response to work indicate normal increase in metabolism but no ongoing inflammation in subjects withTM.

Tidskriftsartikel (refereegranskat)abstract
- Previous studies involving injury surveillance in badminton players have used nonstandardized injury definitions and data collection methodologies. The purpose of this study was to apply a Delphi method to (1) reach a consensus on an injury definition in badminton and (2) develop a standardized badminton injury report form. An Injury Consensus Group was established under the auspices of the Badminton World Federation, and initial injury definitions and injury report form were developed. An internal panel was formed from the Injury Consensus Group, and an external panel was selected based on a combination of profession, experience in the field, sport-specific knowledge/expertise, and geographical location to obtain a widely representative sample. Through 2 rounds of voting by the external panel, consensus was reached on both the definition of an injury in badminton and a standardized injury report form. The agreed injury definition was “Any physical injury sustained by a player during a match or training regardless if further diagnostic tests were done or if playing time was lost” and the injury report form contained the following 7 sections: Injury record, Diagnosis, Injury mechanism, Regarding pain, Pain and return to play/training after injury, Grade of severity, and Recurrence. We recommend the use of the definitions and methods presented in this consensus statement for the reporting of injury in all international and domestic badminton players. This should make future injury surveillance reports directly comparable and hence more informative in recognizing trends over time and differences between countries.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: The controlling culture of a cult can be harmful to its members. Living in and leaving a cult can be challenging, lead to mental illness and experience the need for support.Aims: I - To explore former cult members' perceptions of consultations with healthcare professionals for mental illness that they relate to their cult involvement. The study also aims to identify the needs, obstacles, and facilitating factors related to these consultations. II - To explore the experiences of acculturation into secular Swedish society of former members of cults, with particular focus on mental health, needs and resources. III - To explore exposure to violence and coercive control in cults, and its consequences for mental health.Design: A qualitative approach was used in all studies. Semi structured interviews (I, III) and the cultural formulation interview from DSM -5 (II) were used to collect data. Studies I and II were analyzed using qualitative content analysis with systematic text condensation. Study III was analyzed using reflexive thematic analysis.Participants: Adult former members of ideological or religion-based cults. Studies I and III include nineteen participants who had been in contact with Swedish healthcare professionals due to mental illness related to their cult involvement. Study II include eleven participants.Results: Being a cult member involved constant exposure to threats and violence. The acculturation process after leaving the cult put them in an in-between state and it took time and effort to resettle in mainstream society. They struggled with a persisting coercive bond to the cult's ideals, shame, trauma, and mental health sequalae. In their consultations with healthcare professionals the former cult members remained affected by the cults rules and belief system. This made it harder for them to communicate their needs and accept care.Conclusion: Former cult members face a complex acculturation process while they struggle in several aspects of life with mental health, shame, problems with trust and personal boundaries. To effectively understand and support former cult members, healthcare professionals must consider both the cultural and existential aspects of former cult members' lives, in addition to their mental health and persisting bond to the cult.

- Objective: To explore the experiences of acculturation into secular Swedish society of former members of cults, with particular focus on mental health, needs and resources.Design: Qualitative method using the Cultural Formulation Interview (CFI) from the DSM-5 as an interview guide. Analysis of participants’ experiences of acculturation through systematic text condensation.Participants: Eleven Swedish former members of ideological or religion-based cults.Setting: Swedish mainstream, secular society.Results: Former cult members experience an ‘in-between time’ in the period after leaving the cult and find themselves in a confusing, chaotic state. They describe having lived in an honor culture where acts of violence were normalized. In the cult, they felt disconnected from themselves, and post-cult they try to regain access to their own values and feelings as well as create new bonds with family members and friends outside the cult. They find it hard to talk about their cult background and find relief in communicating with other former cult members. In their post-cult life, they eventually start seeing the world in a brighter, more hopeful way than before. However, they are also at risk of re-experiencing cult-related traumatic events and of new traumatic experiences within the post-cult acculturation process, and of persistent psychological distress.Conclusion: Former cult members face a challenging acculturation process, having lost a functioning worldview upon leaving the cult but not yet gained another to take its place. While the in-between time is often transient, they may need support from the healthcare system, especially regarding mental health concerns, while establishing themselves into mainstream society.

- Objective: This study explores former cult members’ perceptions of consultations with healthcare professionals for mental illness that they relate to their cult involvement. The study also aims to identify the needs, obstacles, and facilitating factors related to these consultations.Design: Qualitative methods using semi-structured interviews that were analyzed using systematic text condensation.Participants: Nineteen former cult members who had been in contact with Swedish healthcare professionals due to mental illness related to their cult involvement.Results: Former cult members remain affected by cult belief systems, rules, and ideations even after leaving a cult. This leads to ambivalence and inner conflict for the former cult member in a healthcare consultation. Care providers are perceived as ignoring cult experiences and lacking knowledge of a cult’s impact on an individual.Conclusions: To understand, help, and work with former cult members, healthcare professionals need to know about cults and the possible impacts of cult involvement. Person- and patient-centeredness in the form of non-judgmental attitudes, validation of experiences, and awareness of the psychosocial situation are important in consultations with these patients. More over, healthcare providers need to acknowledge cultural and existential aspects of a former cult member’s life, both in the present and from earlier experiences in the cult.

- Long-term non-malignant pain from the locomotive system and generalised pain are common health problems, leading to absence from work and causing huge costs for the society. There is evidence that multimodal rehabilitation can lead to reduced influence of pain and increased work ability. Multimodal rehabilitation is often performed in rehabilitation clinics, where patients from sparsely populated areas must stay away from social environment. Rehabilitation of these patients could be easier if rehabilitation facilities were located closer to their homes. In Sweden, there is a political ambition that rehabilitation teams should be formed in primary health care. Different kinds of education programs are used. The results of this project suggest that team-based assessment by specialised pain teams performed together with primary care staff seems to be a valuable way of transferring knowledge in teamwork.

New objective findings after whiplash injuries: High blood flow in painful cervical soft tissue : An ultrasound pilot study
- 2013

Tidskriftsartikel (refereegranskat)abstract
- BackgroundThe presence of high blood flow in the structurally abnormal and painful regions of tendinosis, but not in the normal pain-free tendons, was recently confirmed by colour Doppler (CD) ultrasound (US). Biopsies from the regions with high blood flow demonstrated the presence of sympathetic and sensitive nerve fibres juxtapositioned to neovessels. Grey-scale US and CD are reliable methods used to evaluate structural homogeneity, thickness, and blood flow in the peripheral tendons. The aim of this study was to utilize CD to qualitatively evaluate for the presence of abnormal high blood flow in paravertebral tissues after whiplash injuries in patients with chronic neck pain.MethodsTwenty patients with chronic neck pain after whiplash-associated disorder (WAD) and 20 pain-free control subjects were included in the study. The same experienced radiologist performed all grey-scale US and CD examinations.ResultsMore regions with high blood flow were observed in the patient group than in the control group. At all levels, the high blood flow pattern was detected at the enthesis of the spinous processes and bilaterally juxtapositioned to the facet joints.ConclusionAll regions identified by the patients as painful and tender corresponded to the positive high blood flow found during the CD examination.ImplicationsThese findings document increased blood-flow/neovascularisation at insertions of neck muscles which may indicate that there are pathological neovascularisation with accomanying pain- and sympathetic nerves, similar to what has been found in Achilles-tendinosis. These findings promise that similar treatments that now is successful with Achilles tendinosis, may be effective in the WAD-painful muscle insertions of the neck.

- Background: Pain from the lateral aspect of the elbow is a common symptom in racket sports, both in recreational and competitive players. In Tennis elbow (TE), the pain is elicited from the lateral epicondyle and the common extensor origin just distal of the epicondyle. The symptoms are aggravated by gripping activity and might be related to activity level, in work as well as in recreational or elite racket sports. TE is considered to be an overuse injury of degenerative nature and the diagnose is easily made, based on a typical history and clinical findings.Objective: To present current knowledge concerning management of TE in racket sports by a review of the literature.Methods: Narrative literature review.Results: An overview of TE in racket sports with highlight on the clinical features, alternative diagnoses and suggested treatments in the literature. Since TE is considered to be an overuse injury, the paper also provides advises for training plan besides management until resolution of symptoms.Conclusions: This painful condition is self-limiting with a good prognosis. No treatment has convincingly evidence, besides methods for reducing pain symptoms. When the pain symptoms are under control, it is important that the return to racket sports is gradual.

- Objective: The aim of this study was to evaluate the effects of interdisciplinary team assessment and a 4-wk rehabilitation program in chronic pain patients.Design: This was a longitudinal cohort study evaluating interdisciplinary pain rehabilitation measures in a specialist care setting. A total of 93 women (42.2 +/- 9.5 yrs) with chronic musculoskeletal pain (median pain duration, 8 yrs) were evaluated at assessment and at the start and end of the rehabilitation program. Pain intensity measured with a visual analog scale, pain dimensions measured with the Multidimensional Pain Inventory, and anxiety and depression measured with the Hospital Anxiety and Depression Scale were registered.Results: The participants exhibited significantly improved results of pain and pain-related measures. The results were seen both after the short-term intervention in the form of the interdisciplinary assessment and after the 4-wk rehabilitation program. The improvements seen after the assessment were not related to specific interventions, such as change of medication, and therefore seem to be a result of the interdisciplinary assessment concept as such.Conclusions: Both interdisciplinary assessment and rehabilitation program seem to be effective in chronic pain rehabilitation, at least for women. Further studies are needed to investigate potential sex differences, as well as content and duration for optimal pain rehabilitation programs.

- Objective: The aim of the study was to investigate the noise exposure for different technical officials during a major badminton tournament.Methods: Individual noise exposure for technical officials was measured during the 23rd BWF World Championship, 2017 in Glasgow, Scotland during all days of the tournament.Results: Umpires and on-court-doctors had equivalent noise exposure, when working longer shifts, that exceeded the exposure limit according to the EU 2003/10/EC noise directive. Exposure limits regarding impulse sound was also exceeded during several work shifts during the tournament.Conclusions: Technical officials are exposed to noise levels that exceed current occupational health leg-islation within the EU, and may therefore be at risk of developing hearing related disorders. It is of high importance for the organizers of sports events to reduce the noise exposure for the technical officials by scheduling shorter work periods, but also by providing individual hearing protectors.

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: In tendon research, using ultrasound (US), studies often refer to tendon thickness, structural abnormalities and neovascularisation. The reliability concerning these measurements and evaluations is seldom reported. The aim of this study was to assess the intra- and inter-observer reliability for quantitative measures (thickness) and qualitative evaluations (structure and neovascularisation) of symptomatic and asymptomatic Achilles and patellar tendons with US and colour Doppler using a modified Öhberg score.METHODS: Twenty-eight consecutive patients with symptomatic and asymptomatic Achilles (n = 27) and patellar tendons (n = 26) were included. Tendon anteroposterior thickness was measured. Tendon structure and neovascularisation were evaluated using a modified Öhberg score. US-images were evaluated twice by four independent observers.RESULTS: Mean thickness for Achilles and patellar tendons was 8.4 mm (±2.0) and 5.5 mm (±1.7), respectively. The reliability for measures of distance was high all over (ICC = 0.963-0.999). A moderate-strong correlation was found between observers concerning evaluation of neovascularisation (r = 0.767-0.992) and poor-moderate correlation concerning evaluation of structural changes (r = 0.379-0.837). Intra-observer reliability was moderate strong for evaluations of both tendon structure (k = 0.537-0.873) and neovascularisation (k = 0.639-0.864).CONCLUSIONS: With a strict method for how to measure tendon thickness and set criteria for evaluating structural changes and amount and distribution of neovascularisation, US and colour Doppler is a reliable method for evaluating Achilles and patellar tendons. The modified, 4-graded, Öhberg score was found to be a reproducible instrument for assessment of tendon structure and neovascularisation.

- PURPOSE: Treatment of patellar tendinopathy/jumper's knee with ultrasound-guided sclerosing injections or ultrasound-guided arthroscopic shaving has shown good clinical short-term results. Former studies indicate that the tendon thickness and structure stays unaffected after successful treatment. The aim of this study was to evaluate the sonographic findings and clinical outcome 3-5 years after treatment of patellar tendinopathy with ultrasound-guided sclerosing injections or arthroscopic shaving.METHODS: Fifty-seven patellar tendons (43 patients) with chronic patellar tendinopathy were evaluated, with ultrasound, colour Doppler (CD) and visual analogue scale (VAS) for pain and satisfaction with treatment, 3-5 years after treatment. Functional status was evaluated with a single question-"Back in full loading activity?" yes or no.RESULTS: At endpoint (mean 46 months), there was a significant decrease in anteroposterior thickness of the proximal patellar tendon in patients treated with ultrasound-guided arthroscopic shaving but not after sclerosing injections. Tendon structure had improved, and CD local blood flow had diminished significantly in both groups. There were good clinical results with a significant decrease in VAS for pain after sclerosing injections (VAS 64 ± 18 → 17 ± 23) with 74 % satisfied patients and also after arthroscopic shaving (VAS 77 ± 16 → 13 ± 23) with 80 % satisfied patients. There were no significant differences in VAS between groups. A significant correlation between low local blood flow and high patient satisfaction was found.CONCLUSIONS: Tendon thickness decreased over time after ultrasound-guided arthroscopic shaving, and tendon structure and local blood flow decreased after both treatments. There were good, and similar, clinical results with both methods. LEVEL OF EVIDENCE: III.

- Empathy in the doctor-patient relationship is of great importance and has long been considered a true professional virtue for doctors. Despite the general agreement concerning the importance of empathy, there is no consensus regarding the definition of empathy in medical research. While several quantitative studies, measuring empathy as an individual trait, show a decline in empathy among medical students, other studies have shown that empathy is influenced by contextual factors as well as the availability of role models. Therefore, further studies about the transition from medical school to clinical work also including the perspective of senior doctors are needed. The study presented in this article aims to better understand the clinical conditions for empathy through interviews with senior doctors about their lived experience of empathy. Twelve senior doctors, from different specialities were interviewed using a semi-structured approach. The data was analysed using content analysis. The analysis resulted in the main theme: Empathy as a silent art–a doctor‘s daily balancing act. This main theme comprised three categories: “A tacit, yet language-dependent process”, “A daily balancing act” and “An unsupported path towards mastery”. Doctors face many challenges in their daily balancing act between individual and structural conditions that may affect empathy. In order to maintain and further develop empathy, doctors need working conditions allowing for collegial reflection and conversations that promote empathy.

- Background: Empathy has long been recognized as a fundamental part of the professionalism of doctors and is considered to be both necessary and beneficial to doctor-patient relationships, although empathy is notoriously difficult to define and measure. Previous research on empathy has mostly consisted of quantitative studies measuring and evaluating empathy levels in students or medical residents. The aim of our qualitative study was to explore the lived experience of empathy among medical interns in Sweden.Method: We interviewed 16 medical interns, using semi-structured interviews. Content analysis was used to analyse the interviews.Results: The analysis led to the emergence of a main theme of empathy as being multifaceted and conflictual, consisting of descriptions (subthemes) of “being” and “doing”; of being uncontrollable and contextual; biased and situated and essential and conflictual. Since the components of empathy were also found to be interwoven, to provide a more holistic presentation of the results, we applied a socio-ecological model to the results inspired by Bronfenbrenner.Conclusions: We concluded that empathy is situated and contextual. By using the socioecological model empathy can be described as a systemic interaction between doctor and patient. Based on this we propose a more holistic approach to empathy in medical education to better prepare students for clinical practice.
