Scientific approach, attitudes, and perspectives on research among Swedish physiotherapy students-a cross-sectional study.

BACKGROUND: Scientific evidence is important to evidence-based practice. Hence, the application of evidence-based practice requires relevant skills and an understanding of science, which therefore need to be learned and trained during the undergraduate program in physiotherapy. The aim of this study was to investigate attitudes, perceived competence, and conditions for a scientific approach among physiotherapy students in Sweden, and to compare attitudes and perceived competence between students in different program years. METHODS: Physiotherapy students from six universities (n = 1499) were invited to respond to a digital survey. The survey contained questions regarding attitudes toward science, perceived competence in research interpretations and open comments regarding requirements for a strengthened scientific approach during education. Comparisons between education years were performed with ANOVA/Kruskal‒Wallis test (scale outcomes) and logistic regression (binary outcomes). RESULTS: A total of 466 students responded to the survey. In total, 57% (n = 266) of the students had a high interest in science. No significant difference in interest in science was found between students in the three program years, but 75% (n = 347) reported increased interest during the program. A perceived high ability to understand the structure and performance of scientific studies was reported by 31% (n = 144), to evaluate the methodology by 16% (n = 72) and to interpret statistical results from scientific studies by 12% (n = 55). The lowest perceived competence was reported among students in their second year (p < 0.05). A majority of the students (88%; n = 410) reported a perceived personal need for strengthened conditions for a scientific approach, with suggested prerequisites during education via increased theoretical and applied understanding of the research. CONCLUSION: Even though this study does not fully cover physiotherapy students at all undergraduate programmes in Sweden, the results support that a scientific approach and training should be strengthened during education to enable physiotherapists to understand and interpret science and to fully apply an evidence-based approach in upcoming clinical practice. Both theoretical and applied knowledge and understanding are needed.

Same game, different worlds? General conditions, perceived stress, and associations between stress and past season injuries in elite female and male ice hockey players.

BACKGROUND: Ice hockey is played by women and men but the arena they play in may differ substantially. Potential differences in general conditions to play the sport may be associated to perceived stress, which has shown to be related to athletic injury in other sports. Therefore, this study aimed to describe and compare general conditions for playing ice hockey, stress levels, and the association between perceived stress and injury occurrence among elite female and male players. METHODS: Prior to the 2022-2023 season all female and male players from the top ice hockey leagues in Sweden were invited to an online survey. Players provided information about their general conditions for playing ice hockey and reported perceived stress during the previous season on the Perceived Stress Scale (PSS-10; sum score range 0-40) and current stress on the Single Item Stress Question (SISQ; scale range 1-5). Injuries during the previous season were self-reported on a modified version of the Oslo Sports Trauma Research Center - Overuse Injury Questionnaire. RESULTS: We received responses from 360 players (170 females and 190 males). Female players more frequently reported additional occupations besides ice hockey and less medical support during games and practices than male players (p < .001). General stress levels were significantly higher among female players (mean PSS score [SD]: 17.4 [5.6] vs 14.1 [5.6], p < 0.001; SISQ median [IQR]: 3 [2-3] vs 2 [1-3], p < 0.001). There was a statistically significant but weak correlation between past season injury and perceived stress (PSS score: rho 0.29; SISQ: rho 0.24). This correlation was stronger among males than females (PSS score: 0.38 vs 0.162; SISQ: 0.29 vs 0.16, p's < 0.05). Players with substantial injuries during previous season had higher previous and current stress levels than players without injury, a difference that was largest and statistically significant only among male players. CONCLUSIONS: General conditions for playing elite ice hockey are inequal for female and male athletes. Stress levels of elite ice hockey players were comparable to the general population. Experience of severe injuries during the previous season was associated to higher levels of perceived stress. This association is stronger among male players, which may be due to greater economic dependency.

Sex differences in outcomes after revascularization for acute lower limb ischemia: Propensity score adjusted analysis.

BACKGROUND: Previous reports have suggested higher rates of mortality and amputation for female patients in acute lower limb ischemia (ALI). The aims of the present study were to investigate if there is a difference in mortality, amputation, and fasciotomy between the sexes. METHODS: A retrospective cohort study of consecutive patients undergoing index revascularization for ALI between 2001 and 2018 was conducted. A propensity score was created through a logistic regression with female/male sex as an outcome. Cox regression analyses for 90-day and 1-year mortality, combining major amputation/mortality, and logistic regression for major bleeding and fasciotomy, were performed. All analyses were performed with and without adjusting for propensity score. RESULTS: A total of 709 patients were included in the study of which 45.9% were women. Mean age was 72.1 years. Females were older and had higher rates of atrial fibrillation, embolic disease, and lower estimated glomerular filtration rate, while men more often had anemia and chronic peripheral arterial disease. Mortality at 1 year was 21.2% for women and 14.7% for men. The adjusted hazard ratio for 1-year mortality was 0.99 (95% CI 0.67-1.46). Fasciotomy was performed in 7.1% of female and 12.8% of male patients; the adjusted odds ratio was 0.52 (95% CI 0.29-0.91). CONCLUSION: Sex was not found to be an independent risk factor for mortality or combined major amputation/mortality after revascularization for acute lower limb ischemia, whereas women had lower odds of undergoing fasciotomy. Whether women are underdiagnosed or do not develop acute compartment syndrome in the lower leg as often as men should be evaluated prospectively.

Injury patterns in Swedish elite female and male ice hockey - A cross-sectional comparison of past-season's injuries.

OBJECTIVES: To describe and compare seasonal prevalence, anatomical location, severity, and onset of injuries between female and male elite ice hockey players. DESIGN: Cross-sectional survey study. SETTING: Elite ice hockey. PARTICIPANTS: Swedish elite ice hockey players (170 females & 190 males). MAIN OUTCOME MEASURES: Past season injuries reported on a modified version of the Oslo Sports Trauma Research Center overuse injury questionnaire. Proportions of players who experienced any and substantial problems, as well as respective injury severity scores were presented and compared between sexes. RESULTS: Highest seasonal prevalence was reported for hip/groin [31.1% (n = 112)], lower back [24.2% (n = 87)], and shoulder injuries [23.6% (n = 85)]. Prevalence of injuries was approximately similar between sexes. Substantial injuries were most prevalent in the hip/groin (13.3% [n = 48]) and knee (18.6% [n = 67]) region. Females reported a higher proportion of substantial hip/groin injuries. Most reported injuries were acute except for hip/groin and lower back injuries (74.4% and 81.8% due to overuse). CONCLUSION: Seasonal prevalence of injuries in elite ice hockey players were comparable between sexes. Acute injuries were most common but hip/groin as well as lower back injuries were predominantly due to overuse. The highest reported prevalence was found for hip and groin-, lower back-, and shoulder injuries.

Scientific approach and attitudes among clinically working physiotherapists in Sweden -a cross sectional survey.

BACKGROUND: Evidence based medicine (EBM) should be an endeavor within all healthcare professions. Knowledge and understanding of science are important prerequisites of EBM. OBJECTIVE: The aim was to examine and compare perspectives on science and perceived inhibiting and facilitating factors for the assimilation and implementation of scientific information among clinically working specialist- and non-specialist physiotherapists in Sweden. METHODS: A cross-sectional survey study was conducted via a web-based questionnaire. Clinically active physiotherapists in Sweden were invited to participate. Attitudes and perspectives were compared between physiotherapists with completed or on-going specialist training, and non-specialists. RESULTS: In total, 1165 physiotherapists responded to the survey (75.5%, (n = 870) women, mean age 44.8 (SD 12.1), whereof 25.5% (n = 319) with completed or ongoing specialist training). The majority of participants had a high interest in science but did not consider a general scientific approach to be applied within physiotherapy. The main perceived inhibiting factor for a clinical practice more based on scientific evidence was lack of time. Specialists had in general higher interest and ability to interpret and evaluate science, and prioritized scientific evidence to a higher extent. CONCLUSION: Among respondents, a scientific approach was considered valuable within physiotherapy but not considered fully applied in practice. The higher interest and perceived ability to interpret science among specialists indicates that further education and specialist training can increase both interest and understanding of science among physiotherapists.

Empowerment and enablement and their associations with change in health-related quality of life after a supported osteoarthritis self-management programme - a prospective observational study.

BACKGROUND: Osteoarthritis is a leading cause of disability worldwide. Current treatment supports coping strategies to improve health-related quality of life (HRQoL). The need to predict response to treatment has been raised to personalise care. This study aims to examine change in HRQoL from baseline to three and nine months follow-up after participating in a Supported Osteoarthritis Self-Management Programme (SOASP) and to examine if empowerment and/or enablement were associated with change in HRQoL after a SOASP. METHODS: Patients participating in a SOASP were recruited consecutively between April 2016 and June 2018. The EQ-5D was used to measure HRQoL, the Swedish Rheumatic Disease Empowerment Scale (SWE-RES-23) (score range 1-5) to measure empowerment and the Patient Enablement Instrument (PEI) (score range 0-12) to measure enablement. The instruments were answered before (EQ-5D, SWE-RES-23) and after (EQ-5D, SWE-RES-23, PEI) the SOASP. A patient partner was involved in the research process to enhance the patient perspective. Changes in outcome were examined with paired sample t-test and standardized effect sizes (Cohen´s d). Multiple linear regression analysis was performed to assess potential associations. RESULTS: One hundred forty-three patients participated in baseline measurement. Mean EQ-5D-5 L index score increased significantly from baseline to three months corresponding to a standardised effect size (Cohen´s d) of d = 0.43, 95% CI [0.24, 0.63] (n = 109), and from baseline to nine months d = 0.19, 95% CI [0.01, 0.37] (n = 119). The average EQ VAS score increased significantly from baseline to three months corresponding to a standardised effect size of d = 0.26, 95% CI [0.07, 0.45] (n = 109), and from baseline to nine months d = 0.18, 95% CI [0.00, 0.36] (n = 119). Neither SWE-RES-23 nor PEI at three months follow-up nor the change in the SWE-RES-23 score from baseline to three months follow-up were associated with change in either EQ-5D-5 L index (p > 0.05) or the EQ VAS (p > 0.05). CONCLUSIONS: Health-related quality of life increased after participating in a SOASP. Empowerment and enablement as measured with the SWE-RES-23 and the PEI were not associated with change in HRQoL among patients participating in a SOASP. TRIAL REGISTRATION: ClinicalTrials.gov. Identification number: NCT02974036. First registration 28/11/2016, retrospectively registered.

Short-Term Complications and Outcomes in Pharmaco-Mechanical Thrombolysis First and Catheter-Directed Thrombolysis First in Patients with Acute Lower Limb Ischemia.

BACKGROUND: Pharmaco-mechanical thrombolysis (PMT) has emerged as a treatment option in patients with acute lower limb ischemia (ALI), especially Rutherford IIb (motor deficit) for rapid revascularization, but supportive data is scarce. The aim of the present study was to compare the effects of thrombolysis, complications, and outcomes of PMT first versus catheter-directed thrombolysis (CDT) first in a large cohort of patients with ALI. METHODS: All endovascular thrombolytic/thrombectomy events in patients with ALI performed between January 1st, 2009, and December 31st, 2018 (n = 347) were included. Successful thrombolysis/thrombectomy was defined as complete or partial lysis. Reasons for using PMT were described. Complications such as major bleeding, distal embolization, and new onset of renal impairment, and major amputation and mortality at 30 days were compared between PMT (AngioJet) first and CDT first groups in a multivariable logistic regression model with adjustment for age, gender, atrial fibrillation, and Rutherford IIb. RESULTS: The most common reason for initial use of PMT was the need for rapid revascularization, and the most common reason for use of PMT after CDT was the insufficient effect of CDT. Presentation of Rutherford IIb ALI was more common in the PMT first group (36.2% vs. 22.5%, respectively, P = 0.027). Among the 58 patients receiving PMT first, 36 (62.1%) were terminated within a single session of therapy without need of CDT. The median duration of thrombolysis was shorter (P < 0.001) for the PMT first group (n = 58) compared to the CDT first group (n = 289) (4.0 hr vs. 23.0 hr, respectively). There was no significant difference in amount of tissue plasminogen activator given, successful thrombolysis/thrombectomy (86.2% and 84.8%), major bleeding (15.5% and 18.7%), distal embolization (25.9% and 16.6%), major amputation or mortality at 30-days (13.8% and 7.7%) in the PMT first compared to the CDT first group, respectively. The proportion of new onset of renal impairment was higher in the PMT first compared to the CDT first group (10.3% vs. 3.8%, respectively), and the increased odds (odds ratio 3.57, 95% confidence interval 1.22-10.41) were maintained in the adjusted model. In Rutherford IIb ALI, no difference in rate of successful thrombolysis/thrombectomy (76.2% and 73.8%), complications or 30-day outcomes was found between PMT first (n = 21) and CDT (n = 65) first group. CONCLUSIONS: PMT first appears to be a good treatment alternative to CDT in patients with ALI, including Rutherford IIb. The found renal function deterioration in the PMT first group needs to be evaluated in a prospective, preferably randomized trial.

Factors associated with clinically relevant pain reduction after a self-management program including education and exercise for people with knee and/or hip osteoarthritis: Data from the BOA register.

AIM: To examine the associations between individual- and disease-related factors and the odds of reaching a clinically relevant pain reduction in people with knee and/or hip osteoarthritis (OA) who underwent a first-line self-management program. MATERIALS AND METHODS: An observational registry-based study including people with knee (n = 18,871) and hip (n = 7,767) OA who participated in a self-management program including education and exercise and had data recorded in the Better Management of patients with Osteoarthritis (BOA) register. We used multivariable logistic regression models to study the association between sex, age, body mass index (BMI), education, comorbidity, pain frequency, walking difficulties, willingness to undergo surgery and the odds of reaching a clinically relevant pain reduction (decrease of >33% on a 0-10 NRS scale) 3 and 12 months after the intervention. All analyses were stratified by joint (knee/hip). RESULTS: Both in the short- and long-term follow-up, a younger age (18-65 years), a lower BMI (< 25), a higher level of education (university), the absence of comorbidities impacting the ability to walk, less frequent pain and not being willing to undergo surgery were associated with higher odds of reaching a clinically relevant pain reduction in people with knee OA. We found similar results for people with hip OA, but with larger uncertainty in the estimates (wider 95% CI). CONCLUSION: Our study suggests that early fist line self-management interventions delivered when people have unilateral hip or knee OA with less frequent pain and are unwilling to undergo surgery, may be important for reaching a clinically relevant pain reduction after participation. Providing the most appropriate treatment to the right patient at the right time is a step in reducing the burden of OA for society and the patient.

Prophylactic and Therapeutic Fasciotomy for Acute Compartment Syndrome after Revascularization for Acute Lower Limb Ischemia-Renal and Wound Outcomes.

BACKGROUND: Acute Compartment Syndrome (ACS) is a significant complication after revascularization for acute lower limb ischemia (ALI). High risk patients sometimes undergo prophylactic fasciotomy (PF) to prevent ACS. Patients that develop ACS undergo therapeutic fasciotomy (TF). The optimal timing of fasciotomy has been debated. The aim of this study was to describe and compare renal and wound outcomes in patients undergoing PF and TF. METHODS: A retrospective cohort study including 76 patients undergoing PF (n = 40) or TF (n = 36) after revascularization for ALI between 2006 and 2018. Estimated glomerular filtration rate (e-GFR) was used to evaluate renal function and compare within (paired-samples t-test) and between (analysis of variance) groups. Wound complications and healing time were compiled from the complete wound healing period and compared between groups with Pearson's chi-squared-and log-rank test, respectively. RESULTS: E-GFR improved over the in-hospital period with 8.2 ml/min/1.73 m2 (95% confidence interval [CI] 2.4-14.1, P = 0.007) in the PF group and 4.4 ml/min/1.73 m2 (95% CI 1.2-7.7, P = 0.010) in the TF group, with no significant difference between the 2 groups (0.3 ml/min/1.73 m2, 95% CI -6.7 to 7.4, P = 0.93). The wound infection rate was higher after TF (PF = 60.6 % and TF = 82.4 %, P = 0.048), whereas rate of other wound complications (PF = 61.3 % and TF = 35.3%, P = 0.036) was higher after PF. CONCLUSIONS: Overall wound complications were high, whereas renal function improved during in-hospital stay. A more conservative approach to fasciotomy could avoid unnecessary fasciotomies and reduce wound complications, while holding the potential to sufficiently preserve renal function if fasciotomy is needed for ACS. This would be possible and safe if an early diagnosis and treatment of ACS can be ensured.

Can a workplace dialogue impact the perceived influence of neck and/or backpain on everyday activities and performance at work? A secondary analysis from the randomized controlled trial WorkUp.

BACKGROUND: Neck- and back- pain are highly prevalent conditions in Sweden and world-wide. Such pain often has consequences on everyday activities, work- and personal life. One consequence is work absence and decreased productivity at work. Adding a workplace dialogue to structured physiotherapy was recently found to lead to increased workability, i.e., not being on sick leave during the 12th month of follow up. AIM: The aim of the study was to explore the effect of a workplace dialogue intervention on secondary outcomes: perceived impact of neck and/or back pain on everyday activities and on performance at work, and total days of sick leave during 12 month follow up. A further aim was to examine associations between perceived influence of pain, and sick leave. METHOD: Patients with neck and/or back pain in primary care in the south of Sweden were randomized into structured physiotherapy alone (n = 206) or with the addition of a workplace dialogue (n = 146). Data regarding the pain's influence on everyday activities and on performance at work were collected using weekly text messages for 52 weeks. The pattern of change in perceived influence of neck and/or back pain on everyday activities and performance at work was compared between the groups with linear mixed models. Cross sectional correlations between perceived influence of neck and/or back pain on everyday activities and performance at work, and days of sick leave, during the preceding four weeks at months 3, 6, 9 and 12 were examined. RESULT: We found no differences in change of perceived influence of neck and/or back pain on daily activities or perceived performance at work, or total days of sick leave during the 12 months of follow up between the groups with structured physiotherapy with or without a workplace dialogue. There was a weak to moderate positive correlation between days of sick leave and perceived influence of neck and/or back pain on everyday activities and performance at work (rho 0.28-0.47). CONCLUSION: A workplace dialogue was not found to affect the perceived impact of neck and/or back pain on everyday activities and performance at work.

Experiences of activity monitoring and perceptions of digital support among working individuals with hip and knee osteoarthritis - a focus group study.

BACKGROUND: Mobile health (mHealth), wearable activity trackers (WATs) and other digital solutions could support physical activity (PA) in individuals with hip and knee osteoarthritis (OA), but little is described regarding experiences and perceptions of digital support and the use of WAT to self-monitor PA. Thus, the aim of this study was to explore the experiences of using a WAT to monitor PA and the general perceptions of mHealth and digital support in OA care among individuals of working age with hip and knee OA. METHODS: We conducted a focus group study where individuals with hip and knee OA (n = 18) were recruited from the intervention group in a cluster-randomized controlled trial (C-RCT). The intervention in the C-RCT comprised of 12-weeks use of a WAT with a mobile application to monitor PA in addition to participating in a supported OA self-management program. In this study, three focus group discussions were conducted. The discussions were transcribed and qualitative content analysis with an inductive approach was applied. RESULTS: The analysis resulted in two main categories: A WAT may aid in optimization of PA, but is not a panacea with subcategories WATs facilitate PA; Increased awareness of one's limitations and WATs are not always encouraging, and the second main category was Digital support is an appreciated part of OA care with subcategories Individualized, early and continuous support; PT is essential but needs to be modernized and Easy, comprehensive, and reliable digital support. CONCLUSION: WATs may facilitate PA but also aid individuals with OA to find the optimal level of activity to avoid increased pain. Digital support in OA care was appreciated, particularly as a part of traditional care with physical visits. The participants expressed that the digital support should be easy, comprehensive, early, and continuous.

Associations Between Physical Activity, Self-reported Joint Function, and Molecular Biomarkers in Working Age Individuals With Hip and/or Knee Osteoarthritis.

Objective: Previous research has suggested an association between physical activity (PA), joint function, and molecular biomarkers, but more studies are needed. The aim of this study was to explore the associations between PA or self-reported joint function and molecular biomarkers of cartilage and inflammation in individuals with hip and/or knee osteoarthritis (OA). Specific objectives were to explore the correlations between (1) the change over 3 months in self-reported PA/joint function and the change in molecular biomarkers (2) objectively measured PA and molecular biomarkers measured at 3-month follow-up. Design: Working age participants (n = 91) were recruited from a cluster randomized controlled trial. Self-reported PA, joint function, and serum samples were collected at baseline and after 3 months. Serum concentrations of the inflammatory marker C-reactive protein (CRP) and the cartilage markers Alanine-Arginine-Glycine-Serine (ARGS)-aggrecan, cartilage oligomeric matrix protein (COMP), and type II collagen C2C were analyzed by immunoassays. Objectively measured PA (steps/day) was collected during 12 weeks from activity trackers used by 53 participants. Associations were analyzed with Spearman's rank correlation. Results: There was a weak negative correlation between the change in self-reported PA and the change in COMP (r s = -0.256, P = .040) but not for the other molecular biomarkers. There were no correlations between the change in self-reported joint function and the change in molecular biomarkers or between the average steps/day and the molecular biomarkers at follow-up (r s ⩽ -0.206, P ⩾ .06). Conclusion: In general, no or only weak associations were found between PA/joint function and molecular biomarkers. Future research recommends including participants with lower PA, extend the follow-up, and use a design that allows comparisons.

Promoting work ability with a wearable activity tracker in working age individuals with hip and/or knee osteoarthritis: a randomized controlled trial.

BACKGROUND: Physical activity (PA) may improve work ability and health in individuals with hip and/or knee osteoarthritis (OA). The use of wearable activity trackers (WATs) has been shown to increase PA and improve other health outcomes but little is known concerning their effect on work ability. The objectives of this study were to examine the effect of self-monitoring PA with a WAT on work ability, PA and work productivity among individuals of working age with hip and/or knee OA. METHODS: Individuals (n = 160) were included and cluster-randomized to a Supported Osteoarthritis Self-management Program (SOASP) with the addition of self-monitoring PA using a commercial WAT for 12 weeks (n = 86), or only the SOASP (n = 74). Primary outcome was self-reported work ability measured with the Work Ability Index (WAI) and secondary outcomes were self-reported PA measured with the International Physical Activity Questionnaire - Short Form (IPAQ-SF) and work productivity, measured with the Work Productivity and Activity Impairment scale: Osteoarthritis (WPAI:OA) at baseline and after 3, 6 and 12 months. Data was primarily analysed with linear mixed models. RESULTS: Participants with data from baseline and at least one follow-up were included in the analyses (n = 124). Linear mixed models showed no statistically significant difference between groups regarding pattern of change in work ability or PA, from baseline to follow-ups. Also, neither group had a statistically significant difference in work ability between baseline and each follow-up. CONCLUSION: The SOASP together with self-monitoring PA with a WAT did not have any effect on the primary outcome variable work ability. Participants already at baseline had good work ability and were physically active, which could have reduced the possibility for improvements. Future interventions should target a population with lower work ability and PA-level. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03354091 . Registered 15/11/2017.

Incidence, Prevalence, and Severity of and Risk Factors for Hip and Groin Problems in Swedish Male Ice Hockey Players: A 1-Season Prospective Cohort Study.

CONTEXT: The epidemiologic focus on time loss may underestimate the true magnitude of hip and groin problems in male ice hockey players. OBJECTIVE: To describe the prevalence, incidence, and severity of hip and groin problems (time loss and non-time loss) in Swedish ice hockey players over the course of a season and explore potential preseason risk factors for these conditions. DESIGN: Prospective 1-season cohort study. SETTING: Professional and semiprofessional Swedish ice hockey players. PATIENTS OR OTHER PARTICIPANTS: A total of 12 professional and semiprofessional male ice hockey teams were invited to participate. Of those, 9 teams agreed, and 163 players were included in the analyses. MAIN OUTCOME MEASURE(S): Hip and groin problems in the previous season (time loss, non-time loss), isometric adduction and abduction strength, and 5-second squeeze test results were recorded before the season and served as independent variables in the risk factor analysis. Main outcome measures were cumulative incidence of hip and groin problems, average prevalence, and odds ratios (ORs) for groin problems in season. RESULTS: Cumulative incidence was 45.4% (95% CI = 37.6%, 53.4%) for all problems and 19% (95% CI = 13.3%, 25.9%) for substantial problems. Average prevalence was 14.1% (95% CI = 10.8%, 17.5%) for all and 5.7% (95% CI = 4.3%, 7.2%) for substantial problems. Among reported problems, 69.2% had a gradual onset, and only 17% led to time loss. Players with non-time-loss problems in the previous season had higher odds for new problems (all: OR = 3.3 [95% CI = 1.7, 6.3]; substantial: OR = 3.6 [95% CI = 1.8, 8.4]). Preseason strength was not significantly associated with the odds for subsequent problems. CONCLUSION: Hip and groin problems are common in ice hockey players and may lead to substantial impairments in performance. Only 1 in 5 problems led to time loss, and 7 in 10 had a gradual onset. Non-time-loss problems in the previous season were a significant risk factor for new problems, whereas decreased preseason hip-adduction and -abduction strength was not.

The Perceived Demands of Ice Hockey Goaltending Movements on the Hip and Groin Region: An Elite Coach and Player Perspective.

BACKGROUND: Many ice hockey goaltending techniques force hip joints and groin muscles into extreme ranges of motion, which may increase the risk of hip and groin problems. PURPOSE: To explore how elite goaltenders and goaltending coaches perceive the demands of common goaltending techniques on the hip and groin region. We further explored differences in perception between goaltenders and their coaches as well as between junior (age <20 years) and senior (age ≥20 years) goaltenders. STUDY DESIGN: Cross-sectional survey. METHODS: We developed a model to categorize common ice hockey goaltending techniques into quantifiable units and invited elite goaltenders and coaches in Sweden to complete an online survey. Participants were asked to rate the perceived demands of each technique on the hip and groin using a Likert scale (not at all, slightly, somewhat, very, or extremely demanding). Using the chi-square test, the proportion of participants perceiving each technique as very or extremely demanding were compared between goaltenders and coaches as well as between senior and junior goaltenders. RESULTS: We received responses from 132 goaltenders and 43 coaches. The stances most frequently perceived as very or extremely demanding were the reverse vertical horizontal post-play (40%) and the butterfly save (25%). Among transitions, movements into the post were most frequently rated as very or extremely demanding (11%-40%). Several techniques were perceived as demanding by a larger share of coaches than goaltenders (difference, 13%-46%; P < .001-.028) and a larger share of senior versus junior goaltenders (difference, 12%-20%; P = .13-.18). CONCLUSION: The post-play and the butterfly were the goaltending techniques most frequently perceived as demanding, and more coaches than goaltenders percieved these techniques demanding. The results of this study may inform injury prevention efforts for ice hockey goaltending.

Hip and groin function and strength in male ice hockey players with and without hip and groin problems in the previous season- a prospective cohort study.

OBJECTIVE: To describe and compare hip and groin strength and function of male ice hockey players over one season in players with and without hip and groin problems in the previous season. DESIGN: Prospective cohort study. SETTING: Swedish male ice hockey. PARTICIPANTS: We followed 193 players from 10 teams during the 2017/2018 season. MAIN OUTCOME MEASURES: Hip adduction and abduction strength, 5 s squeeze test (5SST), and self-reported hip and groin function (Hip and Groin Outcome Score). Changes over the season and differences between players with and without problems in the previous season were analyzed by linear mixed models. RESULTS: Adduction strength decreased slightly from pre-to mid-season and abduction strength increased slightly over the full season. However, self-reported function or pain did not change. Players with hip and groin problems in the previous season had significantly worse self-reported function, and more groin pain during the 5SST compared to players without. Strength measurments did not differ between groups. CONCLUSIONS: Hip muscle strength, groin pain, and self-reported function appear to remain stable throughout the season in male ice hockey players. Remaining impairments in players with problems in the previous season suggest that function does not recover by ice hockey participation alone.

Self-Perceived Life Satisfaction during the First Wave of the COVID-19 Pandemic in Sweden: A Cross-Sectional Study.

Currently, there is limited knowledge on how the Swedish strategy with more lenient public health restrictions during the COVID-19 pandemic has influenced people's life satisfaction. Here, we investigated self-reported life satisfaction during the first wave of the pandemic in Sweden, and perceived changes in life satisfaction in relation to various sociodemographic factors. A total of 1082 people (mean age 48 (SD 12.2); 82% women) responded to an online survey during autumn 2020 including the "Life Satisfaction Questionnaire-11". A majority (69%) were satisfied with life as a whole, and with other important life domains, with the exception of contact with friends and sexual life. An equal share reported that life as a whole had either deteriorated (28%) or improved (29%). Of those that perceived a deterioration, 95% considered it to be due to the pandemic. Regarding deteriorated satisfaction with life as a whole, higher odds were found in the following groups: having no children living at home; being middle aged; having other sources of income than being employed; and having a chronic disease. The Swedish strategy might have contributed to the high proportion of satisfied people. Those who perceived a deterioration in life satisfaction may, however, need attention from Swedish Welfare Authorities.

Rapid decline of yearly number of hip arthroscopies in Sweden: a retrospective time series of 6,105 hip arthroscopies based on a national patient data register.

Background and purpose - Hip arthroscopies (HAs) have increased exponentially worldwide and are expected to continue rising. We describe time trends in HA procedures in Sweden (10 million inhabitants) between 2006 and 2018 with a focus on procedure rates, surgical procedures, and patient demographics such as age and sex distribution.Patients and methods - We retrospectively collected data from the Swedish National Patient Register (NPR) for all surgeries including surgical treatment codes considered relevant for HA from 2006 to 2018. Surgical codes were validated through a multiple-step procedure and classified into femoroacetabular impingement syndrome (FAIS) related or non-FAIS related procedure. Frequencies, sex differences, and time trends of surgical procedures and patient demographics are presented.Results - After validation of HA codes, 6,105 individual procedures, performed in 4,924 patients (mean age 34 years [SD 12]) were confirmed HAs and included in the analysis. Yearly HA procedure rates increased from 15 in 2006 to 884 in 2014, after which a steady decline was observed with 469 procedures in 2018. The majority (65%) of HAs was performed in males. Male patients were younger, and surgeries on males more frequently included an FAIS-related procedure.Interpretation - Similar to previous studies in other parts of the world, we found dramatic increases in HA procedures in Sweden between 2006 and 2014. Contrary to existing predictions, HA rates declined steadily after 2014, which may be explained by more restrictive patient selection based on refined surgical indications, increasing evidence, and clinical experience with the procedure.

Physical activity patterns, adherence to using a wearable activity tracker during a 12-week period and correlation between self-reported function and physical activity in working age individuals with hip and/or knee osteoarthritis.

BACKGROUND: A majority of individuals with osteoarthritis (OA) are insufficiently physically active. Self-monitoring with wearable activity trackers (WAT) could promote physical activity (PA), and increased knowledge of PA patterns and adherence to using a WAT is needed. The aim of this study was to describe PA patterns and adherence to WAT-use during an intervention among participants of working age with hip and/or knee OA. The study further explores the correlation between self-reported joint function and PA. METHODS: Individuals of working age with hip and/or knee OA who used a WAT, Fitbit Flex 2, for 12 weeks were included. Participants monitored their PA in the Fitbit-app. An activity goal of 7,000 steps/day was set. Steps and minutes in light (L), moderate and vigorous (MV) PA were collected from the Fitbit. Self-reported joint function (HOOS/KOOS) was completed. Data was analyzed with linear mixed models and Spearman's rank correlation. RESULTS: Seventy-five participants (45-66 years) walked on average 10 593 (SD 3431) steps/day, spent 248.5 (SD 42.2) minutes in LPA/day, 48.1 (SD 35.5) minutes in MVPA/day, 336.0 (SD 249.9) minutes in MVPA/week and used the Fitbit for an average of 88.4 % (SD 11.6) of the 12-week period. 86.7 % took > 7,000 steps/day and 77.3 % spent > 150 min in MVPA/week. Mean daily steps/week decreased significantly over the 12 weeks (ß-coefficient - 117, 95 % CI -166 to -68, p = < 0.001) as well as mean daily minutes in LPA/week (ß-coefficient - 2.3, 95 % CI -3.3 to -1.4, p = < 0.001), mean daily minutes in MVPA/week (ß-coefficient - 0.58, 95 % CI -1.01 to -0.16, p = 0.008) and mean adherence to Fitbit-use per week (ß-coefficient - 1.3, 95 % CI -1.8 to -0.8, p = < 0.001). There were no significant correlations between function (HOOS/KOOS) and PA. CONCLUSIONS: The majority of participants reached 7,000 steps/day and the recommended 150 min in MVPA per week. However, PA decreased slightly but gradually over time. Adherence to using the Fitbit was high but also decreased during the intervention. Understanding PA patterns and the use of a Fitbit to promote PA could be beneficial in tailoring interventions for individuals with hip and/or knee OA.

Improvements After Arthroscopic Treatment for Femoroacetabular Impingement Syndrome in High-Level Ice Hockey Players: 2-Year Outcomes by Player Position.

BACKGROUND: Ice hockey players often undergo arthroscopic treatment for femoroacetabular impingement syndrome (FAIS); however, only a few studies have reported postoperative patient-reported outcomes. It has been debated whether player position is related to FAIS. PURPOSE: To evaluate the change in patient-reported outcome measures (PROMs) in high-level ice hockey players from presurgery to 2 years after arthroscopic treatment for FAIS. The secondary aim was to evaluate differences in outcomes among player positions and whether stick handedness is related to the side of the symptomatic hip. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Ice hockey players undergoing treatment for FAIS between 2011 and 2019 were prospectively included. Preoperative and 2-year follow-up scores were collected for the following PROMs: HAGOS (Copenhagen Hip and Groin Outcome Score), iHOT-12 (12-item International Hip Outcome Tool), EQ-5D (EuroQol-5 Dimensions) and EQ-VAS (EuroQol-Visual Analog Scale), Hip Sports Activity Scale, and visual analog scale for overall hip function. Player position and stick handedness were collected from public sources. Preoperative and follow-up outcomes were compared for the entire cohort and among player positions. RESULTS: The cohort included 172 ice hockey players with a mean age of 28 years, a mean body mass index of 25.6, and a mean symptom duration of 46.3 months. In the 120 players with 2-year follow-up data, there was significant improvement in all PROMs as compared with presurgery: HAGOS subscales (symptoms, 47.5 vs 68.0; pain, 57.0 vs 75.8; activities of daily living, 62.5 vs 81.0; sports, 40.0 vs 64.7; physical activity, 30.9 vs 57.2; quality of life, 32.5 vs 57.8), iHOT-12 (45.2 vs 66.7), EQ-5D (0.59 vs 0.75), EQ-VAS (68.3 vs 73.2), and visual analog scale for overall hip function (49.6 vs 69.2) (P < .0001 for all). At 2-year follow-up, 83% reported satisfaction with the procedure. There was no difference in the improvement in PROMs among player positions. Further, there was no significant relationship between stick handedness and side of symptomatic hip; however, because of the number of bilateral procedures and large number of left-handed shooters, no conclusions could be drawn. CONCLUSION: High-level ice hockey players undergoing arthroscopic treatment for FAIS reported improvements in PROMs 2 years after surgery, regardless of player position.
