- The aims of the study were to evaluate the relative and absolute variability of upper (T11-L2) and lower (L2-S2) lumbar spinal alignment in power- and weightlifters during the deadlift and back squat exercises, and to compare this alignment between the two lifting groups. Twenty-four competitive powerlifters (n = 14) and weightlifters (n = 10) performed three repetitions of the deadlift and the back squat exercises using a load equivalent to 70% of their respective one-repetition maximum. The main outcome measures were the three-dimensional lumbar spinal alignment for start position, minimum and maximum angle of their spinal alignment, and range of motion measured using inertial measurement units. Relative intra-trial reliability was calculated using the two-way random model intraclass correlation coefficient (ICC) and absolute reliability with minimal detectable change (MDC). The ICC ranged between 0.69 and 0.99 and the MDC between 1 degrees-8 degrees for the deadlift. Corresponding figures for the squat were 0.78-0.99 and 1 degrees-6 degrees. In all participants during both exercises, spinal adjustments were made in both thoracolumbar and lumbopelvic areas in all three dimensions. In conclusion, when performing three repetitions of the deadlift and the squat, lumbar spinal alignment of the lifters did not change much between repetitions and did not differ significantly between power- and weightlifters.

- We prospectively studied calf muscle strength in 7 men and 4 women (mean age, 40.9 +/- 10.1 years) who had surgical treatment for chronic Achilles tendinosis. Surgery was followed by immobilization in a weightbearing below-the-knee plaster cast for 2 weeks followed by a stepwise increasing strength training program. Strength measurements (peak torque and total work) were done preoperatively (Week 0) and at 16, 26, and 52 weeks postoperatively. We measured isokinetic concentric plantar flexion strength at 90 and 225 deg/sec and eccentric flexion strength at 90 deg/sec on both the injured and noninjured sides. Preoperatively, concentric and eccentric strength were significantly lower on the injured side at 90 and 225 deg/sec. Postoperatively, concentric peak torque on the injured side decreased significantly between Weeks 0 and 16 and increased significantly between Weeks 26 and 52 at 90 deg/sec but was significantly lower than that on the noninjured side at all periods and at both velocities. The eccentric strength was significantly lower on the injured side at Week 26 but increased significantly until at Week 52 no significant differences between the sides could be demonstrated. It seems, therefore, that the recovery in concentric and eccentric calf muscle strength after surgery for Achilles tendinosis is slow. We saw no obvious advantages in recovery of muscle strength with a short immobilization time (2 weeks) versus a longer (6 weeks) period used in a previous study.

-
Ingår i: British Journal of Sports Medicine. - : BMJ. - 0306-3674 .- 1473-0480. ; 45:5, s. 429-432

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Partial Achilles tendon ruptures are not always easy to diagnose. A history including a sudden onset of pain, and/or relative weakness in plantar flexion force, are indicators. The most loaded side of the Achilles tendon is the dorsal side (skin side). OBJECTIVE: To evaluate the ultrasound (US) and Doppler (CD) findings in patients with a suspected partial rupture in the Achilles tendon. Material and METHODS: Seventeen patients (16 men and 1 woman) with a mean age of 36 years (range 23-71) were examined clinically and by US+CD because of midportion Achilles tendon pain. There was an acute onset in 14/17 patients, and all had painful weakness during tendon loading activity. RESULTS: In all patients the US examination showed a partial Achilles tendon rupture, presented as a disrupted dorsal (skin side) tendon line and an irregular tendon structure mainly located in the dorsal and mid-tendon. The size of the rupture varied from 1/3 to 2/3 of the tendon thickness. In the dorsal part of the tendon, corresponding to the region with disrupted tendon line and irregular structure, CD examination showed high blood flow-most often of a longitudinal character. Six of the patients were surgically treated, and macroscopical examination verified the ultrasound findings, showing disruption on the dorsal side, and a partial rupture in the dorsal and mid- tendon. CONCLUSIONS: Ultrasound and Doppler examination can be helpful tools to diagnose partial midportion Achilles tendon ruptures. The characteristic findings of a disrupted dorsal tendon line, and high blood flow in the structurally abnormal dorsal tendon, indicate a partial rupture.

- Treatment with ultrasound and Doppler-guided arthroscopic shaving of the region with vessels and nerves outside the dorsal tendon has shown promising clinical results in patients with proximal patellar tendinopathy/Jumper´s knee. The results concerning only a limited patient material has been published in a scientific paper. Results on larger materials are under evaluation for later publication. Proper understanding of the ultrasound and Doppler findings, to enable for a precise and minimal arthroscopic shaving procedure on the dorsal side of the tendon, are cornerstones using this new type of treatment.

- OBJECTIVE: The aim of this study was to evaluate whether mobile kidney pain provocation ultrasonography together with intravenous pyelography in supine and standing positions and a full medical history can confirm the diagnosis of the clinical condition of symptomatic mobile kidney and aid the selection of patients for surgical treatment.MATERIALS AND METHODS: In a consecutive study, 43 patients with the clinical picture of symptomatic mobile kidney, a positive mobile kidney pain provocation ultrasonography and a renal descent of at least 2 lumbar vertebral heights on intravenous pyelography in the standing position, were operated on with nephropexy. Patients' pain relief after nephropexy was evaluated by clinical follow-up, a questionnaire and visual analogue scale (VAS) scoring.RESULTS: Reduction of pain after nephropexy was associated with a significant decrease in VAS scoring from a median of 8 (range 4-10) preoperatively to a median of 0 (range 0-7) postoperatively (p < 0.001). Thirty-four patients (79%) were cured of their pain and seven patients (16%) experienced substantial relief from their pain symptoms. In two patients (5%) the symptoms were unchanged.CONCLUSION: The results indicate that mobile kidney pain provocation ultrasonography and intravenous pyelography in supine and standing positions can verify the diagnosis of symptomatic mobile kidney and aid the selection of patients who will benefit from nephropexy.

- Symtomatic mobile kidney is a rare condition and diagnosis is difficult. Typical symptoms are position dependent back-flank-abdominal pain with increase of pain when walking, jogging and lifting or other physical activities which increase the descent of the kidney. Triple diagnostic with typical pain history, an intravenous pyelography with a renal descent of ≥ 2 lumbar vertebral heights in the erect position, and an ultrasound with a positive pain provocation can establish the diagnosis of symptomatic mobile kidney. In our study nephropexy gives freedom of pain for 75% of patients and substantial relief for 15% of patients with severe pain.

- Background: Maintaining neutral spinal alignment is considered important when performing the barbell back squat exercise. Since male and female lifters may differ in injury location it is important to examine whether they differ in spinal alignment during the back squat.Objectives: The study aimed to quantify the spinal alignment in the upper and lower lumbar spine during the barbell back squat exercise in male and female lifters. Secondary aims were to compare alignment during the back squat to standing habitual lumbar spine alignment and determine whether male and female lifters differ in these aspects.Study design: Observational, Cross-sectional.Methods: Competitive power- and weightlifters were recruited and performed three repetitions of the barbell back squat exercise using a load equivalent to 70% of their one-repetition maximum. Spinal alignment and range of motion were measured using inertial measurement units placed on the thoracic, lumbar and sacral spine. Data was presented descriptively and comparisons between men and women as well as spinal alignment in four different positions were done with a factorial repeated measures analysis of variance.Results: Twenty-three (14 males, 9 females) were included. During execution of the squat, spinal alignment adjustments in the lumbar spine were made in all three planes of movement, compared to the start position, in both male and female lifters. Compared to their standing habitual posture, all lifters adjusted their upper lumbar spine to a less lordotic position when in the start position of the back squat (standing upright with the barbell on their back). Only male lifters assumed a less lordotic alignment in their lower lumbar spine in the start position compared their habitual posture.Conclusions: Adjustments of spinal alignment, predominantly in the sagittal plane, are made during execution of the back squat in both male and female lifters. Further, lifters adopt a less lordotic alignment with a heavy barbell on their upper back, more so in male than female lifters. In conclusion, it seems that spinal alignment changes noticeably during the barbell back squat.Level of evidence: 3

- Background: A neutral spinal alignment is considered important during the execution of the deadlift exercise to decrease the risk of injury. Since male and female powerlifters experience pain in different parts of their backs, it is important to examine whether men and women differ in spinal alignment during the deadlift.Objectives: The purpose of this study was to quantify the spinal alignment in the upper (thoracolumbar, T11-L2) and lower (lumbopelvic, L2-S2) lumbar spine during the deadlift exercise in male and female lifters. Secondary aims were to compare lumbar spine alignment during the deadlift to standing habitual posture, and determine whether male and female lifters differ in these aspects.Study Design: Observational, Cross-sectional.Methods: Twenty-four (14 men, 10 women) lifters performed three repetitions of the deadlift exercise using 70% of their respective one-repetition maximum. Spinal alignment and spinal range of motion were measured using three inertial measurement units placed on the thoracic, lumbar and sacral spine. Data from three different positions were analyzed; habitual posture in standing, and start and stop positions of the deadlift, i.e. bottom and finish position respectively.Results: During the deadlift, spinal adjustments were evident in all three planes of movement. From standing habitual posture to the start position the lumbar lordosis decreased 13° in the upper and 20° in the lower lumbar spine. From start position to stop position the total range of motion in the sagittal plane was 11° in the upper and 22° in the lower lumbar spine. The decreased lumbar lordosis from standing habitual posture to the start position was significantly greater among men.Conclusions: Men and women adjust their spinal alignment in all three planes of movement when performing a deadlift and men seem to make greater adjustments from their standing habitual posture to start position in the sagittal plane.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To investigate the long-term effects on cognition and brain function after installing treadmill workstations in offices for 13 months.Methods: Eighty healthy overweight or obese office workers aged 40–67 years were individually randomized to an intervention group, receiving a treadmill workstation and encouraging emails, or to a control group, continuing to work as usual. Effects on cognitive function, hippocampal volume, prefrontal cortex (PFC) thickness, and circulating brain-derived neurotrophic factor (BDNF) were analyzed. Further, mediation analyses between changes in walking time and light-intensity physical activity (LPA) on changes in BDNF and hippocampal volume between baseline and 13 months, and multivariate analyses of the baseline data with percentage sitting time as the response variable, were performed.Results: No group by time interactions were observed for any of the outcomes. In the mediation analyses, positive associations between changes in walking time and LPA on changes in hippocampal volume were observed, although not mediated by changes in BDNF levels. In the multivariate analyses, a negative association between percentage sitting time and hippocampal volume was observed, however only among those older than 51 years of age.Conclusion: Although no group by time interactions were observed, our analyses suggest that increased walking and LPA may have positive effects on hippocampal volume and that sedentary behavior is associated with brain structures of importance for memory functions.Trial Registration: www.ClinicalTrials.gov as NCT01997970.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Recent studies have revealed structural changes with neovessels in patients with jumper's knee and Achilles tendinopathy, and treatment with sclerosing injections has shown promising clinical results. PURPOSE: To study the prevalence of neovascularization and structural tendon changes on color Doppler ultrasound examination in elite athletes with clinical symptoms of jumper's knee and to examine the ultrasound characteristics of the tendon after sclerosing injection treatment with polidocanol. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The authors recruited patients among elite athletes with a clinical diagnosis of jumper's knee who participated in a previous randomized clinical trial. The patients recorded knee function using the Victorian Institute of Sport Assessment score. Patients were examined by color Doppler ultrasound at baseline and, for patients with structural changes and neovascularization who received sclerosing treatment, after treatment. RESULTS: Sixty-three patients (11 women and 52 men) with 79 symptomatic tendons were studied. The ultrasound examination revealed that neovascularization was present in 48 of the 79 tendons (60%). Of 33 patients (43 tendons) who received sclerosing injections, 29 patients (37 tendons, 86%) were examined 37 (19 to 53) weeks after their final sclerosing injections. Of these, 7 tendons (18.9%) had no change in neovascularization after treatment, 21 tendons (56.8%) had less neovascularization, and 9 tendons (24.3%) had more visible neovascularization. There were no significant differences in the change in Victorian Institute of Sport Assessment score between patients who had less, more, or unchanged neovascularization after treatment (analysis of variance, P = .9). CONCLUSION: About two thirds of patients with jumper's knee can be expected to have structural tendon changes with neovascularization. There was no relationship between changes in ultrasound characteristic and knee function after sclerosing treatment.

- 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.

- The intramuscular activation pattern can be connected to the motor unit recruitment strategy of force generation and fatigue resistance. Electromyography has earlier been used in several studies to quantify the spatial inhomogeneity of the muscle activation. We applied ultrasound M-mode strain to study the activation pattern through the tissue deformation. Correlation values of the strain at different force levels were used to quantify the spatial changes in the activation. The assessment was done including the biceps brachii muscle of 8 healthy subjects performing isometric elbow flexion contractions ranging from 0% to 80% of maximum voluntary contraction. The obtained results were repeatable and demonstrated consistent changes of the correlation values during force regulation, in agreement with previously presented EMG-results. Both intra-subject and inter-subject activation patterns of strain were considered along and transverse the fiber direction. The results suggest that ultrasound M-mode strain can be used as a complementary method to study intramuscular activation patterns with high spatial resolution.(C) 2013 Elsevier Ltd.

- Tissue velocity imaging (TVI) is a Doppler based ultrasound technique that can be used to study regional deformation in skeletal muscle tissue. The aim of this study was to develop a biomechanical model to describe the TVI strain's dependency on the pennation angle. We demonstrate its impact as the subsequent strain measurement error using dynamic elbow contractions from the medial and the lateral part of biceps brachii at two different loadings; 5% and 25% of maximum voluntary contraction (MVC). The estimated pennation angles were on average about 4 degrees in extended position and increased to a maximal of 13 degrees in flexed elbow position. The corresponding relative angular error spread from around 7% up to around 40%. To accurately apply TVI on skeletal muscles, the error due to angle changes should be compensated for. As a suggestion, this could be done according to the presented model.

- Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? This is the first presented results and second publication on detection of tumour-draining lymph nodes in human renal cell carcinoma. Techniques are displayed and tumour-draining patterns are presented. OBJECTIVE: • To evaluate the feasibility of performing sentinel node detection in patients with renal cell carcinoma (RCC). MATERIALS AND METHODS: • An open series of 13 arbitrarily selected patients with T1b-T3b RCC scheduled for radical nephrectomy at a single Tertiary Academic Centre were examined with different modalities of sentinel node detection. • Preoperative ultrasonography-guided injection of radioactive isotope, lymphoscintigram and single photon emission computed tomography/computed tomography, followed by intraoperative gamma-probe detection and Patent Blue detection, as well as postoperative scintigram of the main specimen were the planned interventions. • These investigations were performed in conjunction with intended open radical nephrectomy. RESULTS: • In 10 of the 13 patients sentinel node detection was achieved with 32 sentinel nodes displayed. • Radio-guided surgery using an intraoperative gamma-probe resulted in the highest realtive detection rate with detection of sentinel nodes in nine patients. • In total, nine metastatic sentinel nodes were detected in three patients. • One patient, preoperatively staged as N+, was restaged after sentinel node detection and histopathology as pN0. CONCLUSIONS: • Sentinel node detection in renal tumours is feasible although evaluation of different modes of detection needs further refinement and standardization. • All nodes preoperatively detected by routine computed tomography as suspicious metastatic lesions were confirmed as sentinel nodes, including two nodes considered as metastatic by preoperative routine imaging but ultimately staged as non-metastatic sentinel nodes.

- Two to three ultrasound (US) and colour Doppler (CD)-guided injections of the sclerosing substance Polidocanol (5 mg/ml) have been demonstrated to give good clinical results in patients with chronic midportion Achilles tendinopathy. This study aimed to investigate if a higher concentration of Polidocanol (10 mg/ml) would lead to a less number of treatments, and lower volumes, needed for good clinical results. Fifty-two consecutive Achilles tendons (48 patients, mean age 49.6 years) with chronic painful midportion Achilles tendinopathy, were randomised to treatment with Polidocanol 5 mg/ml (group A) or 10 mg/ml (group B). The patients and treating physician were blinded to the concentration of Polidocanol injected. All patients had structural tendon changes and neovascularisation in the Achilles midportion. Treatment was US + CD-guided injections targeting the region with neovascularisation (outside ventral tendon). A maximum of three treatments (6-8 weeks in between) were given before evaluation. Patients not satisfied after three treatments were given additional treatment with Polidocanol 10 mg/ml, up to five treatments. For evaluation, the patients recorded the severity of Achilles tendon pain during activity on a visual analogue scale (VAS), before and after treatment. Patient satisfaction with treatment was also assessed. At follow-up (mean 14 months) after three treatments, 18/26 patients in group A and 19/26 patients in group B were satisfied with the treatment and had a significantly reduced level of tendon pain (P < 0.05). After completion of the study, additional treatments with Polidocanol 10 mg/ml in the not satisfied patients resulted in 26/26 satisfied patients in both groups A and B. In summary, we found no significant differences in the number of satisfied patients, number of injections or volumes given, between patients treated with 5 or 10 mg/ml Polidocanol.

- Background Tennis elbow is a tendinopathy affecting the upper extremity. Recent studies have shown high sensitivity for ultrasound (US) examination and high specificity for colour Doppler (CD) examination. There are no mid- or long-term follow-up investigations of the tendon structure and blood flow using these techniques. Objective To use US and CD to study structure and blood flow in the extensor origin in patients with tennis elbow treated with intratendinous injections. Design Follow-up study Setting Sports Medicine Unit, Umeå University. Patients 25 patients (28 elbows), mean age 46 years (range 27–66), treated with intratendinous injections due to chronic pain from tennis elbow. Method US and CD examination of the extensor origin was carried out at inclusion and at follow-up two years after intratendinous injection treatment with polidocanol and/or a local anaesthetic. Main outcome measurements US (structure) and CD (blood flow) findings. Results All patients had structural tendon changes and high blood flow at inclusion when given the injection treatment. At the two-year follow-up, structural tendon changes were seen in 20/28 elbows and high blood flow was seen in 4/28 elbows. The majority of patients with a good clinical result after treatment had no visible blood flow (17/20), but the structural changes showed no relation to a good result (13/20 remaining changes). Conclusions Doppler findings, but not structure, might be related to the clinical result after intratendinous injection treatment of tennis elbow.

- “Tennis elbow” is a difficult condition to treat. Ultrasonography (US) and colour Doppler (CD) guided injections with polidocanol targeting the area with increased blood flow in the extensor origin have shown promising clinical results.Objective:To evaluate and compare effects of US and CD guided intratendinous injections with sclerosing polidocanol and a local anaesthetic (lidocaine + epinephrine), in patients with tennis elbow.Design:Prospective, randomised, controlled, double-blind, crossover study.Setting:Sports Medicine Unit, Umeå University.Patients:32 patients (36 elbows), age range 27 to 66 years, with a long duration of elbow pain diagnosed as tennis elbow, were included in the study. All patients were followed up 3 and 12 months after treatment. Two patients were excluded due to other interventions during the study.Interventions:One US and CD guided injection with the sclerosing agent polidocanol (group 1) or the local anaesthetic lidocaine plus epinephrine (group 2). At the 3 month follow-up, additional injections with polidocanol were offered to both groups (crossover for group 2).Main outcome measures:Satisfaction with treatment (Yes/No), elbow pain during activity (visual analogue scale), and maximum voluntary grip strength.Results:There were no significant (p<0.05) differences in the outcome between group 1 and group 2. In both groups, there was a significantly lower VAS at the 3-month and 12-month follow-ups, and grip strength was significantly higher at the 12-month follow-up.Conclusions:US and CD guided intratendinous injections gave pain relief in patients with tennis elbow. Polidocanol and lidocaine plus epinephrine injections gave similar results.

- Objective: To prospectively investigate tendon thickness and tendon structure by ultrasonography in patients treated with eccentric calf muscle training for painful chronic Achilles tendinosis located at the 2 6 cm level in the tendon.Methods: The patients were examined with grey scale ultrasonography before and 3.8 years ( mean) after the 12 week eccentric training regimen. At follow up, a questionnaire assessed present activity level and satisfaction with treatment.Results: Twenty six tendons in twenty five patients ( 19 men and six women) with a mean age of 50 years were followed for a mean of 3.8 years ( range 1.6 - 7.75). All patients had a long duration of painful symptoms ( mean 17.1 months) from chronic Achilles tendinosis before treatment. At follow up, 22 of 25 patients were satisfied with treatment and active in Achilles tendon loading activities at the desired level. Ultrasonography showed that tendon thickness ( at the widest part) had decreased significantly (p< 0.005) after treatment (7.6 (2.3) v 8.8 ( 3) mm; mean (SD)). In untreated normal tendons, there was no significant difference in thickness after treatment (5.3 (1.3) mm before and 5.9 (0.8) mm after). All tendons with tendinosis had structural abnormalities (hypoechoic areas and irregular structure) before the start of treatment. After treatment, the structure was normal in 19 of the 26 tendons. Six of the seven patients with remaining structural abnormalities experienced pain in the tendon during loading.Conclusions: Ultrasonographic follow up of patients with mid-portion painful chronic Achilles tendinosis treated with eccentric calf muscle training showed a localised decrease in tendon thickness and a normalised tendon structure in most patients. Remaining structural tendon abnormalities seemed to be associated with residual pain in the tendon.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the present thesis was to evaluate sonographic methods for investigation of the chronic painful Achilles tendon. In a prospective study on patients with chronic painful mid-portion Achilles tendinosis, grey-scale ultrasound (US) showed a decreased tendon thickness and a “normalized” structure in the majority of patients successfully treated with eccentric calf-muscle training. By combining US with colour Doppler examination (CDV), a neovascularisation was shown in the region with structural tendon changes in all painful tendons, but not in any of the pain-free normal tendons. In a small pilot study, the sclerosing agent Polidocanol was injected towards the neovessels under US and CDV guidance. The majority of the patients became painfree and had no remaining neovessels, while the patients with remaining pain had remaining neovessels. The combined findings from US, immuno-histochemical analyses of biopsies, and diagnostic injections, showed that the patients were temporarily pain-free after US and CDV guided injections of local anaesthesia towards the region with neovessels, and biopsies from the region with tendon changes and neovascularisation showed nerve structures in close relation to blood vessels. The presence of neovessels was shown also in patients with chronic pain in the Achilles tendon insertion, and it was found that treatment with sclerosing injections cured the pain in the majority of patients. A good result of treatment was associated with no remaining neovessels. In a prospective study on patients with chronic mid-portion Achilles tendinosis treated with eccentric training, CDV after treatment showed no remaining neovessels in the majority of the pain-free patients. In the patients with remaining tendon pain there were remaining neovessels. In conclusion, the findings in this thesis indicate that neovessels and accompanying nerves might be the source of chronic Achilles tendon pain. Sclerosing injections towards the neovessels, and eccentric training, seem to have a potential to cure the pain.
