RESUMO
IMPORTANCE: A sense of agency is associated with complex occupation-related responsibilities. A taxonomy can guide clinicians in enhancing responsibility in patients with Parkinson's disease (PwPD). OBJECTIVE: To (1) discover levels of responsibility in occupations for PwPD and (2) propose a taxonomy for occupations. DESIGN: A two-round Delphi study with PwPD and a one-round Delphi study with international experts. SETTING: Electronic survey. PARTICIPANTS: PwPD (N = 75) and international experts (N = 8). OUTCOMES AND MEASURES: PwPD expressed their levels of an inherent sense of responsibility for each occupation (1 = very low responsibility, 5 = very high responsibility). International experts rated their level of agreement (5 = strongly agree, 1 = strongly disagree) with each dimension of the taxonomy. A consensus was determined to have been reached if the interquartile range was ≤1 and 70% agreement in two adjacent categories was achieved. RESULTS: Thirty-three occupation categories were deemed as having very high to moderate responsibility for PwPD. Consequences of actions and the presence of others made up the two-dimensional responsibility taxonomy. Occupations have more challenging responsibility characteristics when they are performed with free choice, a level of high physical effort, alone, and with moral consequences. CONCLUSIONS AND RELEVANCE: This study yielded the first consensus among PwPD regarding responsibility in occupations as well as a classification system for charting the complexity of responsibility in occupations. The occupation list we have created can be beneficial to health care professionals when providing interventions or conducting outcome assessments. Plain-Language Summary: When planning interventions for patients with Parkinson's disease, it can be helpful for clinicians to be aware of patients' perspectives regarding their sense of responsibility to perform occupations. The use of a systematic sequence of challenging occupations with responsibility attributes ranging from less complex to more complex can help enhance patient occupational participation.

BACKGROUND: Movement behaviours, such as sedentary behaviour (SB) and moderate to vigorous physical activity (MVPA), are linked with multiple aspects of health and can be influenced by various pain-related psychological factors, such as fear of movement, pain catastrophising and self-efficacy for exercise. However, the relationships between these factors and postoperative SB and MVPA remain unclear in patients undergoing surgery for lumbar degenerative conditions. This study aimed to investigate the association between preoperative pain-related psychological factors and postoperative SB and MVPA in patients with low back pain (LBP) and degenerative disc disorder at 6 and 12 months after lumbar fusion surgery. METHODS: Secondary data were collected from 118 patients (63 women and 55 men; mean age 46 years) who underwent lumbar fusion surgery in a randomised controlled trial. SB and MVPA were measured using the triaxial accelerometer ActiGraph GT3X+. Fear of movement, pain catastrophising and self-efficacy for exercise served as predictors. The association between these factors and the relative time spent in SB and MVPA 6 and 12 months after surgery was analysed via linear regression models, adjusting for potential confounders. RESULTS: Preoperative fear of movement was significantly associated with relative time spent in SB at 6 and 12 months after surgery (ß = 0.013, 95% confidence interval = 0.004 to 0.022, p = 0.007). Neither pain catastrophising nor self-efficacy for exercise showed significant associations with relative time spent in SB and MVPA at these time points. CONCLUSIONS: Our study demonstrated that preoperative fear of movement was significantly associated with postoperative SB in patients with LBP and degenerative disc disorder. This finding underscores the potential benefits of preoperative screening for pain-related psychological factors, including fear of movement, preoperatively. Such screenings could aid in identifying patients who might benefit from targeted interventions to promote healthier postoperative movement behaviour and improved health outcomes.

BACKGROUND: Cerebral palsy (CP) is an umbrella term where an injury to the immature brain affects muscle tone and motor control, posture, and at times, the ability to walk and stand. Orthoses can be used to improve or maintain function. Ankle-foot orthoses (AFOs) are the most frequently used orthoses in children with CP. However, how commonly AFOs are used by children and adolescents with CP is still unknown. The aims of this study were to investigate and describe the use of AFOs in children with CP in Sweden, Norway, Finland, Iceland, Scotland, and Denmark, and compare AFO use between countries and by gross motor function classification system (GMFCS) level, CP subtype, sex, and age. METHOD: Aggregated data on 8,928 participants in the national follow-up programs for CP for the respective countries were used. Finland does not have a national follow-up program for individuals with CP and therefore a study cohort was used instead. Use of AFOs were presented as percentages. Logistic regression models were used to compare the use of AFOs among countries adjusted for age, CP subtype, GMFCS level, and sex. RESULTS: The proportion of AFO use was highest in Scotland (57%; CI 54-59%) and lowest in Denmark (35%; CI 33-38%). After adjusting for GMFCS level, children in Denmark, Finland, and Iceland had statistically significantly lower odds of using AFOs whereas children in Norway and Scotland reported statistically significantly higher usage than Sweden. CONCLUSION: In this study, the use of AFOs in children with CP in countries with relatively similar healthcare systems, differed between countries, age, GMFCS level, and CP subtype. This indicates a lack of consensus as to which individuals benefit from using AFOs. Our findings present an important baseline for the future research and development of practical guidelines in terms of who stands to benefit from using AFOs.

Several risk factors for injury have been suggested in female elite athletes. However, there is a lack of prospective studies in young female athletes where multiple risk factors have been studied. The aim of this study was to identify risk factors for injury in female adolescent elite athletes. Substantial injuries were monitored in 222 athletes using the validated Oslo Sports Trauma Research Centre Questionnaire over 20 weeks. Over 20 potential risk factors were explored. Based on a binomial generalized linear mixed model, two significant (p<0.05) risk factors for injury were identified; previous injury within the last 12 months (OR 2.55) and well-being (OR 0.97). An athlete with a previous injury had twice as high a risk of injury (13% vs. 6%) compared to an athlete with no previous injury. Higher perceived well-being was associated with a decreased risk of injury. Based on a prospective design with a large sample of female adolescent elite athletes, investigating over 20 potential risk factors for injury, our results suggest that a previous injury and well-being are risk factors for injury.

Exposure to critical body weight comments in youth athletes could lead to decreased self-esteem, affect body image, and increase the risk of eating disorders and cause depressive symptoms. The aim was to explore differences between sex, body mass index, sports type, with regards to body weight satisfaction, exposure to critical body weight comments from their coach and nutrition status in adolescent elite athletes. A questionnaire about body weight, critical body weight comments and nutrition was distributed to 489 adolescent elite athletes and injury prevalence was monitored across 20 weeks. The results showed that almost one in four athletes (n=116, 24%) was not satisfied with their weight and 12% (n=59) had received critical body weight comments from their coach. Of the athletes who were unsatisfied with their body weight (n=116), 47% wanted to lose weight (n=55). A significant (p<0.05) higher proportion of ice hockey players and swimmers used nutritional supplements, were unsatisfied with their body weight, and were more exposed to critical body weight comments compared to athletes from other sports. Adolescent elite athletes as young as 15-16 years old are exposed to critical body weight comments from their coach and experience challenges with body weight satisfaction that is partly dependent on the sport-specific context.

IMPORTANCE: Sense of agency is associated with a sense of responsibility, which is essential to performing goal-directed occupations. OBJECTIVE: To reach consensus on a set of extrinsic feedback statements that have the potential to create a sense of responsibility among patients with neurological disorders in the course of performing daily or social occupations. DESIGN: Anonymous Delphi study with two rounds with international experts and one round with Irani patients with Parkinson's disease (PD). SETTING: Electronic survey. PARTICIPANTS: One hundred experts and 73 patients with idiopathic PD. OUTCOMES AND MEASURES: Experts and patients anonymously rated (5 = strongly agree/very effective, 4 = agree/effective, 3 = neither agree nor disagree/uncertain, 2 = disagree/ineffective, 1 = strongly disagree/very ineffective) their level of agreement with each survey statement and the effectiveness of each statement in creating a sense of responsibility in the course of performing daily or social occupations. Consensus was set as an interquartile range of ≤1 and ≥70% agreement in two adjacent categories of a Likert scale. RESULTS: In the experts' first round, consensus was reached on the level of agreement and effectiveness of 18 statements. In the second round, final consensus was achieved on all statements. In the one patient round, patients reached consensus on all statements. Finally, 34 statements were rated as 4 or 5 in terms of agreement and effectiveness, based on the opinions of experts and patients. CONCLUSIONS AND RELEVANCE: This study has produced a collection of feedback statements that might be useful in occupation-based interventions. What This Article Adds: Extrinsic responsibility feedback delivered while administering occupation-based interventions may increase volition, motivation, and engagement.

IMPORTANCE: The ability to perform voluntary actions is disrupted in Parkinson's disease (PD). Voluntary activities play a critical role in generating sense of agency, which underpins the concept of responsibility for people's daily occupations and their outcomes. According to this concept, the dearth of research regarding the concept of responsibility in rehabilitation hampers practitioners in delivering evidence-based care. OBJECTIVE: To generate a list of occupations that enhance an inherent sense of responsibility among people with PD that is based on consensus among experts. DESIGN: An anonymous and iterative Delphi study with two rounds. SETTING: Electronic survey. PARTICIPANTS: One hundred sixteen experts participated in the first round of the study, and 95 participated in the second round. OUTCOMES AND MEASURES: Panelists rated the level of inherent responsibility in each occupation and the importance of types of patient-related information on a 5-point Likert scale. Consensus was defined as reaching an interquartile range of >1. RESULTS: In the first round, consensus was reached on 19 occupations and all 38 types of patient-related information. Also, an additional 15 occupations and 16 types of patient-related information were added to the lists. Consensus was reached for all occupations and patient-related information presented in the second round. CONCLUSIONS AND RELEVANCE: Our results indicate that 61 occupations were deemed to enhance a moderate to a very high inherent sense of responsibility among people with PD. In addition, a wide range of patient-related information is considered very important or important while these occupation-focused interventions are delivered. What This Article Adds: Subjective knowledge of one's actions and their consequences lies behind people's daily occupations. Considering this knowledge when administering occupation-focused interventions can be beneficial for individuals with PD.

BACKGROUND: Perineal tears are common after vaginal birth and may result in pelvic floor symptoms. However, there is no validated questionnaire that addresses long-term symptoms in women with a deficient perineum after vaginal birth. Thus, the objective of this study was to develop and psychometrically evaluate a clinical screening inventory that estimates subjective symptoms in women with a deficient perineum more than one year after vaginal delivery. MATERIAL AND METHODS: The development and psychometric evaluation employed both qualitative and quantitative methods. Qualitative strategies involved content validity and Think Aloud protocol for generation of items. The psychometric evaluation employed principal component analysis to reduce the number of items. The inventory was completed by women with persistent symptoms after perineal tears (N = 170). Results were compared to those of primiparous women giving birth by caesarean section (N = 54) and nulliparous women (N = 338). RESULTS: A preliminary 41-item inventory was developed, and the psychometric evaluation resulted in a final 11-item inventory. Women with confirmed deficient perineum after perineal trauma scored significantly higher on the symptoms inventory than women in control groups. A cut-off value of ≥ 8 could distinguish patients from controls with high sensitivity (100%) and specificity (87-91%). CONCLUSIONS: The Karolinska Symptoms After Perineal Tear Inventory, is a psychometrically valid 11-item patient-reported outcome measure for symptoms of deficient perineum more than one year after vaginal birth. More research is needed to validate the inventory in various patient populations as well as its use in pelvic floor interventions. The inventory has the potential to improve patient counseling and care in the future.

BACKGROUND: One's physical function and physical activity levels can predispose or protect from the development of respiratory infections. We aimed to explore the associations between pre-pandemic levels of physical function and physical activity and the development of COVID-19-like symptoms in Swedish older adults. METHODS: We analyzed data from 904 individuals aged ≥ 68 years from the population-based Swedish National study on Aging and Care in Kungsholmen. COVID-19-like symptoms were assessed by phone interview (March-June 2020) and included fever, cough, sore throat and/or a cold, headache, pain in muscles, legs and joints, loss of taste and/or odor, breathing difficulties, chest pain, gastrointestinal symptoms, and eye inflammation. Muscle strength, mobility, and physical activity were examined in 2016-2018 by objective testing. Data were analyzed using logistic regression models in the total sample and stratifying by age. RESULTS: During the first outbreak of the pandemic, 325 (36%) individuals from our sample developed COVID-19-like symptoms. Those with slower performance in the chair stand test had an odds ratio (OR) of 1.5 (95% confidence interval [CI] 1.1-2.1) for presenting with COVID-19-like symptoms compared to better performers, after adjusting for potential confounders. The association was even higher among people aged ≥ 80 years (OR 2.6; 95% CI 1.5-4.7). No significant associations were found between walking speed or engagement in moderate-to-vigorous physical activity and the likelihood to develop COVID-19-like symptoms. CONCLUSION: Poor muscle strength, a possible indicator of frailty, may predispose older adults to higher odds of developing COVID-19-like symptoms, especially among the oldest-old.

BACKGROUND: Identifying physical activity (PA) profiles of people with Parkinson's Disease (PD) could provide clinically meaningful knowledge concerning how to tailor PA interventions. Our objectives were therefore to i) identify distinct PA profiles in people with PD based on accelerometer data, ii) explore differences between the profiles regarding personal characteristics and physical function. METHODS: Accelerometer data from 301 participants (43% women, mean age: 71 years) was analysed using latent profile analyses of 15 derived PA variables. Physical function measurements included balance performance, comfortable gait speed and single and dual-task functional mobility. RESULTS: Three distinct profiles were identified; "Sedentary" (N = 68), "Light Movers" (N = 115), "Steady Movers" (N = 118). "Sedentary" included people with PD with high absolute and relative time spent in Sedentary behaviour (SB), little time light intensity physical activity (LIPA) and negligible moderate-to-vigorous physical activity (MVPA). "Light Movers" were people with PD with values close to the mean for all activity variables. "Steady Movers" spent less time in SB during midday, and more time in LIPA and MVPA throughout the day, compared to the other profiles. "Sedentary" people had poorer balance (P = 0.006), poorer functional mobility (P = 0.027) and were more likely to have fallen previously (P = 0.027), compared to "Light Movers. The Timed Up and Go test, an easily performed clinical test of functional mobility, was the only test that could distinguish between all three profiles. CONCLUSION: Distinct PA profiles, with clear differences in how the time awake is spent exist among people with mild-moderate PD.

STUDY DESIGN: Cross-sectional validation study. OBJECTIVES: Explore psychometric properties of Spinal Cord Injury Secondary Conditions Scale (SCI-SCS). SETTING: Two Scandinavian rehabilitation centres. METHODS: Included were 224 consecutive patients attending regular follow-up at least 1 year after a traumatic SCI. Mean age was 49.6 (SD 14.9) years. SCI-SCS floor and ceiling effect examined. Construct validity was investigated by confirmatory factor analysis and correlation analysis, and reliability by Cronbach's alpha. RESULTS: SCI-SCS showed no floor or ceiling effect. Two out of four earlier reported latent factors ("Genitourinary and bowel", "Muscle structures and pain") were confirmed. The global Cronbach's alpha of SCI-SCS was 0.65 and 0.22-0.61 for the four latent factors. The SCI-SCS sum score showed low correlation to quality of life (QoL) measured by EQ5 VAS (rs = -0.47, p < 0.001). Likewise, the sum score correlations to QoL-general and QoL-physical health (International SCI QoL Basic Dataset) were low (rs = -0.36, p < 0.001 and rs = -0.37, p < 0.001, respectively). The scale item Muscle Spasms correlated moderately to ratings on Spasm Frequency (rs = 0.59, p < 0.001) and Spasm Intensity (rs = 0.56, p < 0.001) scales. Chronic Pain and Joint and Muscle Pain correlated to patient reported number of pain sites and level of pain (International SCI Pain Basic Dataset 1.0) (rs = 0.31 p < 0.001 and rs = 0.47, p < 0.001, respectively). CONCLUSION: SCI-SCS is a relevant instrument for giving clinicians and researchers an overview of the individual recent experiences with secondary conditions. However, the instrument could benefit from a clearer definition of the construct secondary conditions, a scale revision and a consideration of whether to add other experienced secondary conditions.

OBJECTIVE: To examine the joint associations of daily time spent in different intensities of physical activity, sedentary behaviour and sleep with all-cause mortality. METHODS: Federated pooled analysis of six prospective cohorts with device-measured time spent in different intensities of physical activity, sedentary behaviour and sleep following a standardised compositional Cox regression analysis. PARTICIPANTS: 130 239 people from general population samples of adults (average age 54 years) from the UK, USA and Sweden. MAIN OUTCOME: All-cause mortality (follow-up 4.3-14.5 years). RESULTS: Studies using wrist and hip accelerometer provided statistically different results (I2=92.2%, Q-test p<0.001). There was no association between duration of sleep and all-cause mortality, HR=0.96 (95% CI 0.67 to 1.12). The proportion of time spent in moderate to vigorous physical activity was significantly associated with lower risk of all-cause mortality (HR=0.63 (95% CI 0.55 to 0.71) wrist; HR=0.93 (95% CI 0.87 to 0.98) hip). A significant association for the ratio of time spent in light physical activity and sedentary time was only found in hip accelerometer-based studies (HR=0.5, 95% CI 0.42 to 0.62). In studies based on hip accelerometer, the association between moderate to vigorous physical activity and mortality was modified by the balance of time spent in light physical activity and sedentary time. CONCLUSION: This federated analysis shows a joint dose-response association between the daily balance of time spent in physical activity of different intensities and sedentary behaviour with all-cause mortality, while sleep duration does not appear to be significant. The strongest association is with time spent in moderate to vigorous physical activity, but it is modified by the balance of time spent in light physical activity relative to sedentary behaviour.

By exploring multiple characteristics of physical activity and sedentary behavior (SB), different physical activity profiles could be obtained, which may be beneficial for health and targeted physical activity interventions. The aim of this study was to identify distinct physical activity profiles based on accelerometer-derived activity characteristics and to determine whether these profiles are associated with all-cause mortality. Eight hundred fifty-one participants (56% women, mean age: 53 years) provided objectively assessed physical activity data using an ActiGraph accelerometer and were followed for 15 years. Physical activity profiles were determined using latent profile analyses of 14 derived activity variables, resulting in that three profiles were identified: "Low Active" (n = 147), "Average Active" (n = 397), and "High Active" (n = 307). "Low Active" was characterized by participants with low absolute, relative, and limited variation of time spent in physical activity, and high time spent in SB. "Average Active" had the most balanced movement behavior with values close to the mean for all activity variables. "High Active" was characterized by participants with high absolute, relative, and great variation of time spent in physical activity. Overall, a potentially non-linear pattern between multiple activity variables and all-cause mortality was found as "Low Active" was significantly (P < .05) positively associated with all-cause mortality, and no difference in mortality risk was found between "High Active" and "Average Active." Our data suggest that day-to-day variation in SB is not associated with all-cause mortality. The important message is to keep the overall time spent in SB low and replace this behavior with physical activity.

The association between the composition of movement behaviors and mortality risk, acknowledging the composition nature of daily time data, is limited explored. The aim was to investigate how the composition of time spent in sedentary behaviors (SB), light intensity physical activity (LIPA), and moderate-to-vigorous physical activity (MVPA) is associated with all-cause mortality, in a cohort with 15 years follow-up time, using compositional data analysis. Eight hundred fifty-one participants (56% women, mean age 53 years) provided objectively assessed physical activity data using an ActiGraph accelerometer and were followed for 15 years. Association of daily time composition of movement behaviors with risk of mortality was explored using compositional data analysis and hazard ratios (HR) of mortality were estimated based on a cox regression model. A significant (P < .001) positive association between time spent in SB relative to time in other behaviors and a significant (P = .018) negative association between time spent in LIPA relative to time in other behaviors, with all-cause mortality, were found. Substituting time spent in LIPA or MVPA with time in SB increased the hazard for all-cause mortality, with greater effect found for MVPA (20 minutes replacement; HR 1.26, 95% CI 1.04-1.52) than for LIPA (20 minutes replacement; HR 1.06, 95% CI 0.65-1.73). In a public health perspective, it is recommended to substitute SB with either LIPA or MVPA, but for individuals with little time spent in MVPA, the most important message may be to try to maintain that behavior.

BACKGROUND: The Single Leg Squat (SLS) test is widely used in the clinical setting to examine and evaluate rehabilitation goals. It is simple to perform and is proposed to have biomechanical and neuromuscular similarities to athletic movements. The aim of the present study was to investigate whether demographics, previous injuries, and biomechanical and psychosocial factors are associated with the outcome of the SLS, assessed as a total score for all segments and as a separate knee segment in elite and sub-elite female soccer players. METHODS: We conducted a cross-sectional study involving 254 female soccer players (22 yrs; SD ± 4, height 1.69 m; SD ± 0.1, weight 64 kg; SD ± 6) from divisions 1-3 of the Swedish Soccer League. During the preseason, we assessed the participants using the SLS and tested their hip strength and ankle mobility. Demographics, previous injury, sleep quality, fear of movement, anxiety, and perceived stress were assessed with questionnaires. Logistic regression models were built to analyse the association between the outcome of the SLS and the independent variables for the dominant and non-dominant leg. RESULTS: Significantly more participants failed the SLS on the dominant leg compared with the non-dominant leg (p < 0.001). The outcome of the SLS associated with various biopsychosocial factors depending on if the dominant or non-dominant leg was tested. The total score associated with hip strength for the dominant (OR 0.99, 95% CI 0.98-0.99, p = 0.04) and the non-dominant leg (OR 0.99, 95% CI 0.97-0.99, p = 0.03). The knee segment associated with division level for the dominant (div 2; OR 2.34, 95% CI 1.01-5.12, p = 0.033. div 3; OR 3.07, 95% CI 1.61-5.85, p = 0.001) and non-dominant leg (div 2; OR 3.30, 95% CI 1.33-8.00, p = 0.01. div 3; OR 3.05, 95% CI 1.44-6.43, p = 0.003). CONCLUSIONS: This study identified that leg dominance, division level, hip strength, and psychosocial factors were associated with the outcome of the SLS when assessed as a total score and as a separate knee segment. This indicates that clinicians need to understand that movement control is associated with factors from several domains. Whether these factors and, the results of the SLS are related to injury need to be studied prospectively. TRIAL REGISTRATION: Clinical Trials Gov, date of registration 2022-03-01.

RESUMO
BACKGROUND: Many studies have identified key factors affecting the rates of engagement in physical activity in older adults with chronic disease. Environmental conditions, such as weather variations, can present challenges for individuals with chronic diseases, such as type 2 diabetes when engaging in physical activity. However, few studies have investigated the influence of weather on daily steps in people with chronic diseases, especially those with prediabetes and type 2 diabetes. OBJECTIVE: This study investigated the association between weather variations and daily self-monitored step counts over two years among individuals with prediabetes and type 2 diabetes in Sweden. METHODS: The study is a secondary analysis using data from the Sophia Step Study, aimed at promoting physical activity among people with prediabetes and type 2 diabetes, which recruited participants from two urban primary care centers in Stockholm and one rural primary care center in southern Sweden over eight rounds. This study measured physical activity using step counters (Yamax Digiwalker SW200) and collected self-reported daily steps. Environmental factors such as daily average temperature, precipitation, and hours of sunshine were obtained from the Swedish Meteorological and Hydrological Institute. A robust linear mixed-effects model was applied as the analysis method. RESULTS: There was no association found between weather variations and the number of steps taken on a daily basis. The analysis indicated that only 10% of the variation in daily steps could be explained by the average temperature, precipitation, and sunshine hours after controlling for age, gender, and BMI. Conversely, individual factors explained approximately 38% of the variation in the observations. CONCLUSION: This study revealed that there was no association between weather conditions and the number of daily steps reported by individuals with prediabetes and type 2 diabetes taking part in a physical activity intervention over two years. Despite the weather conditions, women and younger people reported more steps than their male and older counterparts.

BACKGROUND: The menstrual cycle and its impact on training and performance are of growing interest. However, evidence is lacking whether periodized exercise based on the menstrual cycle is beneficial. The primary purpose of this proposed randomized, controlled trial, the IMPACT study, is to evaluate the effect of exercise periodization during different phases of the menstrual cycle, i.e., comparing follicular phase-based and luteal phase-based training with regular training during the menstrual cycle on physical performance in well-trained women. METHODS: Healthy, well-trained, eumenorrheic women between 18 and 35 years (n = 120) will be recruited and first assessed for physical performance during a run-in menstrual cycle at different cycle phases and then randomized to three different interventions: follicular phase-based training, luteal phase-based training, or regular training during three menstrual cycles. The training intervention will consist of high-intensity spinning classes followed by strength training. The menstrual cycle phases will be determined by serum hormone analysis throughout the intervention period. Assessment of aerobic performance (primary outcome) and muscle strength, body composition, and blood markers will be performed at baseline and at the end of the intervention. DISCUSSION: With a robust methodology, this study has the potential to provide evidence of the differential effects of exercise periodization during different phases of the menstrual cycle in female athletes.

INTRODUCTION: Adolescent elite athletes have a high injury risk and many risk factors for injury have been suggested, where the most conclusive risk factor is a previous injury. However, there is a lack of longitudinal data on a complete season in adolescent elite athletes. OBJECTIVES: The aim of the study was to explore the relationship between substantial injuries and previous injuries in adolescent elite athletes. A secondary aim was to explore sex differences in terms of this relationship. METHODS: Injury problems and substantial injury was monitored in adolescent elite athletes (n = 320) using the validated the Oslo Sports Trauma Research Center Questionnaire over 52 weeks. RESULTS: In total, 74% (n = 237) athletes reported at least one substantial injury during the study period. Previous injury problems were reported by 82% (n = 195), where 48% (n = 183) of all substantial injuries occurred within the same body location as a previous injury. Forty-four percent (n = 83) of the substantial injuries occurred within 2 weeks after occurrence of an injury problem. There was no association between sex and number of substantial injuries (p = .956, χ2 = 1.7). Poisson regression analysis demonstrated that 16-year-old athletes had a significantly (p = .034) increased risk of reporting substantial injuries (IRR 1.19, 95% CI: 1.01-1.39), compared to 18-year-old athletes. A high prevalence of substantial injuries occurred closely followed a previous injury in the same body location. CONCLUSION: Exploring rehabilitation following injuries in this age, addressing injury risk behavior when an injury problem has occurred and increasing awareness of the relationship between injury problems and substantial injuries are suggested to be important strategies to reduce substantial injuries in adolescent elite athletes.

INTRODUCTION: Injury prevention is important to reduce the high injury risk in youth elite athletes studying at sports high schools. Coaches are considered important in youth elite sports and injury prevention. OBJECTIVES: The aim was to investigate perceptions and experiences of injury prevention among coaches at sports high schools. METHODS: A manifest qualitative content analysis with an inductive approach was used based on ten semi-structured interviews with coaches who work at sports high schools. RESULTS: An overarching theme "Coaches of youth athletes value injury prevention but have limited knowledge and support" was identified and five main categories were formed. Coaches perceived themselves to play an important role in injury prevention, yet they described limited time for knowledge acquisition and highlighted the close collaboration with other professions as a key in injury prevention. CONCLUSION: A coach's knowledge and support are critical factors in injury prevention of youth elite athletes. Evidence-based as well as non-evidence-based approaches are used, and the biopsychosocial perspective was not always taken into consideration. A need for more interprofessional collaboration and knowledge acquisition regarding injury prevention is warranted.

Background: Adolescent elite athletes have a high injury risk and many risk factors for injury have been suggested. However, there is a lack of prospective studies in adolescent elite athletes of age 15-16 years. Aim: The aim of the study was to prospectively explore risk factors associated with different injury prevalence profiles in adolescent elite athletes. Methods: Substantial injury was monitored in adolescent elite athletes (n=422) using the validated Oslo Sports Trauma Research Center Questionnaire over 20 weeks. Athletes were categorised in tertiles based on injury prevalence. Results: The median substantial injury prevalence for all athletes was 10% (IQR 0%-20%). Compared with the 'no injury' group, previous injury (p<0.001, OR 3.91) and well-being (p<0.001, OR 0.93) were associated with the 'high injury' group, and previous injury (p=0.006, OR 1.96) and being a female athlete (p=0.002, OR 2.08) with the 'low injury' group. A female athlete with a previous injury and low perceived well-being (25th percentile) had a 48% risk (95% CI 36% to 59%) of belonging to the 'high injury' group, compared with 7% (95% CI 4% to 12%) for a male athlete with no previous injury and high well-being (75th percentile). Conclusion: Medical personnel should be aware of the high injury risk and risk factors for injury in adolescent elite athletes, and closely monitor the rehabilitation post-injury as a previous injury is such a strong risk factor for a new injury.
