  • Stress Fractures of Pars Interarticularis in Adolescent Athletes a Classification System with MRI and CT Enabling Evaluation of The Healing Process
  • 2018
  • Ingår i: Journal of Exercise, Sports & Orthopedics. - 2374-6904. ; 5:1
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Introduction: The purpose of this study was to evaluate healing frequency in different stages of stress reactions in the Pars Interarticularis (PI) using a classification system with MRI and CT. The intervention was 3-month rest from physical activity, without a brace, with the exception of activities of daily living.</p><p>Materials &amp; Method: Twelve adolescent athletes with different stages of Spondolysis were included in the study. They had pathology in the Pars Interarticularis and were clinically examined with MRI and CT 3-6 weeks after debut of Low Back Pain (LBP) and re-evaluated after 3 months intervention with rest from physical activity.</p><p>Results: A combination of MRI and CT scanning to investigate suspected injuries to Pars Interarticularis in adolescent athletes revealed 6 different stages of Spondolysis that ranged from marrow oedema to pseudoarthrosis. After 3 months of rest from physical activity the early stages of Pars Interarticularis injuries healed significantly better than the later stages with rest from physical activity.</p><p>Conclusion: The combination of MRI and CT revealed 6 stages of stress reactions instead of 4 as in Hollenberg’s staging with MRI only. In the 3 earliest stages, of these 6, rest from physical activity for 3 months can heal the stress reaction.</p>

  • Physical performance and muscular characteristics in different stages of COPD
  • 2009
  • Ingår i: Scandinavian Journal of Medicine and Science in Sports. - Wiley-Blackwell Publishing Inc.. - 0905-7188 .- 1600-0838. ; 19:6, s. 865-870

    • <p>This study has examined exercise capacity and muscle morphology in patients with different severities of chronic obstructive pulmonary disease (COPD). Twenty-three patients and 12 healthy matched controls were recruited. Based on the severity of airflow obstruction, patients were divided into two subgroups. Exercise capacity was determined using a 6-min walk test. Muscle fiber composition, fiber area and number of satellite cells/muscle fiber were determined in muscle biopsies using immunohistochemistry. A progressive decline in exercise capacity was noted with ascending disease severity. Furthermore, a correlation between reduction in exercise capacity and changes in muscle fiber composition was observed in COPD. The group with severe and very severe COPD had a lower proportion of type I and a higher proportion of type IIa fibers compared with the other groups. In severe and very severe COPD, a reduction in fiber area of type IIa fibers was also seen. The number of satellite cells/muscle fiber did not differ between the groups. In conclusion, a decline in exercise capacity occurs already in mild and moderate COPD, indicating that the 6-min walk test is a reliable indicator of disease severity. Furthermore, changes in skeletal muscle morphology are associated with disease severity while muscle regenerative capacity is not altered.</p>

    • <p>OBJECTIVE:</p> <p>To measure the graded relation between cardiorespiratory fitness and sum of skinfolds, waist circumference, and blood pressure in children and adolescents participating in the European youth heart study.</p> <p>METHODS:</p> <p>The participants were 4072 children and adolescents (aged 9 and 15) from Denmark, Portugal, Estonia, and Norway. Cardiorespiratory fitness was indirectly determined using a maximal ergometer cycle test. The sum of four skinfolds, waist circumference, and blood pressure were assessed with a standardised protocol. Linear regression analysis was used to test the graded relation between cardiorespiratory fitness and the dependent variables adjusted for pubertal stage, sex, and country.</p> <p>RESULTS:</p> <p>A significant curvilinear graded relation was found between cardiorespiratory fitness and waist circumference and sum of skinfolds (partial r2 for cardiorespiratory fitness was 0.09-0.26 for the different sexes and age groups). Systolic and diastolic blood pressure also showed a curvilinear relation with cardiorespiratory fitness, and fitness explained 2% of the variance in systolic blood pressure. The difference in systolic blood pressure between the least and most fit was 6 mm Hg.</p> <p>CONCLUSION:</p> <p>A curvilinear graded relation was found between cardiorespiratory fitness and waist circumference, sum of skinfolds, and systolic blood pressure. The greatest difference in these health variables was observed between low and moderate fitness levels.</p>

  • Improved intramuscular blood flow and normalized metabolism in lateral epicondylitis after botulinum toxin treatment
  • 2009
  • Ingår i: Scandinavian Journal of Medicine and Science in Sports. - Wiley-Blackwell Publishing Inc.. - 0905-7188 .- 1600-0838. ; 19:3, s. 323-328

    • <p>Lateral epicondylitis is a common cause of elbow pain, and decreased microcirculation in extensor carpi radialis brevis (ECRB) has recently been suggested to contribute to the symptoms. The purpose of this pilot study was to investigate the treatment response after injection of botulinum toxin type A. Ten patients with unilateral epicondylitis and decreased intramuscular blood flow in ECRB participated. Handgrip, 2-pinch grip and muscle strength during radial deviation and dorsal extension of the wrist were recorded. Perceived pain during contraction was evaluated with the Visual Analogue Scale (VAS) and function in daily activities was assessed using the Disability of Arm, Shoulder and Hand instrument (DASH) and the Canadian Occupational Performance Measure instrument (COPM). Intramuscular blood flow was recorded by laser Doppler flowmetry, and microdialysis was used to analyze muscle metabolism. The difference in intramuscular blood flow between the control and the affected side had decreased 3 and 12 months after treatment (P=0.03). Lactate concentration at the 12-month follow-up had decreased (P=0.02); perceived pain was reduced and function in daily activities had improved. Injection of botulinum toxin is an alternative treatment for epicondylitis. Symptom relief may be due to enhanced microcirculation causing an aerobic metabolism.</p>
  • Kultur och hälsa i praktiken
  • 2016
  • Samlingsverk (redaktörskap) (övrigt vetenskapligt)abstract
    • Intresset för området kultur och hälsa är stort. Åtskilliga verksamheter i kommuner och landsting arbetar aktivt med kultur och hälsa. Därför blir det allt viktigare att ta tillvara på den kunskap som skapas inom dessa verksamheter och att möjliggöra ett utbyte av erfarenheter. "Kultur och hälsa i prakten" presenterar i fjorton kapitel hur man kan arbeta med kultur och hälsa inom olika verksamheter som exempel på gränsöverskridande samarbeten mellan praktik och forskning. Kapitalförfattarna är både förankrade i ett konkret verksamhetsområde och i akademisk forskning. "Kultur och hälsa i praktiken" ger en beskrivning av praktiska verksamheter utifrån aktuell forskning. Den syftar till inspiration såväl som fördjupad kunskap för praktiker, forskare, beslutsfattare, kulturutövare, journalister och hälso- och sjukvårdspersonal.

  • The potential of different countermeasures to prevent injuries with high risk of health loss among bicyclists in Sweden
  • 2020
  • Ingår i: Traffic Injury Prevention. - 1538-9588. ; 21:3, s. 215-221
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: As bicyclists account for the largest share of serious injuries in Sweden, focus to improve safety for bicyclists is needed. While knowledge about fatal bicycle crashes is rather extensive, the number of studies that have investigated non-fatal injuries is still rather limited. The aim of this study was to estimate the potential of different countermeasures to reduce crashes resulting in injuries with high risk of health-loss among cyclists in Sweden. A further aim was to describe the residual—that is, crashes that were not considered to be addressed by the analyzed countermeasures. Methods: A sample of individuals with specific injury diagnoses was drawn from the Swedish national crash database Strada. A survey form was used to collect additional information about the crash and the health-related outcomes. The potential of countermeasures currently included in the Swedish Safety Performance Indicators, as well as of countermeasures that could be described as “existing but not fully implemented” was assessed. The overall potential of all countermeasures assessed was calculated, giving a grand total without double counting. Cases that were considered not to be addressed by any of the countermeasures included (i.e., the residual crashes) were described in more detail. Results: The current Swedish Safety Performance Indicators that relate to safe cycling addressed 22% of crashes. Improved maintenance by deicing and removal of snow from bicycle infrastructure was found to have the highest potential (8%), followed by improved crashworthiness of passenger cars (5%) and safer bicycle crossings (4%). The potential for existing but not fully implemented safety improvements was 56%. The greatest potential was found for Autonomous Emergency Braking with cyclist detection for passenger cars (12%), followed by studded winter tyres for bicycles (12%), and improved maintenance on non-bicycle infrastructure (11%). In total, taking double counting into consideration, all safety improvements could address 64% of all crashes. Among the residual crashes, the majority (69%) were single bicycle crashes of which most were related to wheel locking during braking and losing balance at low speed or stationary. Conclusions: Compared with fatal crashes that involve a majority of bicycle-car crashes, the crashes leading to health-loss are mostly single bicycle crashes. Therefore, innovation and development of additional countermeasures to improve safety for bicyclists should focus on single bicycle crashes.

  • Influence of moderate, daily,physical activity upon body composition and blood lipid profile in swedish adults
  • 2012
  • Ingår i: Journal of Physical Activity and Health. - 1543-3080 .- 1543-5474. ; 9, s. 867-874
  • Tidskriftsartikel (refereegranskat)abstract
    • <p><strong>Background:</strong> Health organizations suggest that adults ought to engage in at least 30 minutes of moderate-intensity daily physical activity. This study investigated the effects of a 30-minute single daily bout of brisk walking upon risk factors for CHD with blood lipid profile in particular. <strong>Methods:</strong> Thirty-three (25-45 y) adults, were randomly assigned into an exercise group (EG) (n=16, (9w) and a control group (CG) (n=17 (6w). The EG walked briskly 30 minutes daily during the 3 weeks test period. Compliance/adherence was maximal throughout the 3-week intervention due to stringent daily monitoring. <strong>Results:</strong> The EG showed a significant decrease in concentrations of low density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) during the intervention period. A significant inverse correlation between Δ energy expenditure/day and Δ LDL-C (r = -0.39, P&lt;0.05) and an improvement in weight and BMI in the EG was found. Average steps during 30 minutes brisk walking bout was 3669 steps/bout generating a mean energy expenditure of 191 kcal/bout. <strong>Conclusions: </strong>The most unique findings were that daily single bouts of moderate-intensity physical activity for 30 minutes, during 3 weeks, induced favourable effects upon body weight, BMI and blood concentration of LDL-C and TC in healthy adults.</p>
