Short-term high-intensity interval training improves micro- but not macrovascular function in hypertensive patients.

INTRODUCTION: Arterial hypertension is a global health burden that affects vascular structure and function. Assessment of endothelial function can improve cardiovascular (CV) risk stratification. Exercise treatment reduces over all CV risk and improves vascular health. However, it is still not clear which part of the vascular bed is most sensitive to exercise treatment in patients with CV risk. This study aimed to investigate the effects of an 8-week walking based and supervised high-intensity interval training (HIIT) on macro- and microvascular endothelial function as add-on therapy in patients with arterial hypertension. METHODS: Forty patients (mean age 58 ± 7 years) treated for arterial hypertension were randomized in the HIIT (3×/week) or control group (CG) receiving standard physical activity recommendations. Arteriolar (aFID) and venular (vFID) flicker light-induced dilatation for retinal microvascular and flow-mediated dilatation (FMD) for macrovascular endothelial function were assessed. In addition, standardized assessments of patients' characteristics were performed before and after 8 weeks. RESULTS: Both groups reduced weight and body mass index but only the HIIT group reduced body fat, visceral fat, and increased peak oxygen uptake after 8 weeks. The control group reduced diastolic blood pressure. No blood pressure changes were found in the HIIT group. Arteriolar FID increased in the HIIT group independently of confounders (pre: 2.40 ± 0.98%, post: 3.19 ± 1.31%, p < 0.001) but not in the control group (pre: 3.06 ± 1.50%, post: 2.90 ± 1.46%, p = 0.280). No changes were found for FMD in either group. CONCLUSION: Arteriolar FID was found to be a sensitive vascular biomarker to assess exercise-induced microvascular improvements even in a short time setting of an 8-week exercise therapy with HIIT. Short-term exercise training affects microvascular endothelial function but not large artery endothelial function. Thus, retinal aFID appears to be a sensitive biomarker to detect short-term exercise efficacy on a vascular level. Dynamic retinal vessel analysis as a diagnostic approach may prove to be an ideal candidate vascular biomarker to monitor treatment effects of exercise in patients with hypertension on top of standard clinical care and may support clinical decision-making in the future.

Creating a sport and exercise medicine undergraduate syllabus: a delphi study.

BACKGROUND: Sport and Exercise Medicine (SEM) is a growing speciality in the United Kingdom (UK). This growth has not been replicated in SEM teaching at an undergraduate level and SEM-related topics in schools of medicine in the UK are under-represented. As SEM continues to develop as a specialty it is important to consider how it is embedded at all levels of training. The aim of this project was to establish a consensus on SEM-related skills and knowledge relevant for undergraduate medical students in the UK, ultimately creating a curriculum of learning objectives (LOs). METHODS: A modified Delphi survey was utilised to seek consensus on LOs suitable for incorporation into UK medical school curricula. An expert panel with adequate knowledge in the field was recruited. The initial curriculum was created by the research team using already established postgraduate SEM curricula. All learning objectives were sent to the expert panel for opinions in phases. Levels of agreement and comments made by the expert panel were reviewed after each phase until a consensus on each learning objective was made. RESULTS: The expert panel was made up of 45 individuals, with 35 also completing phase 2 (78% retention rate). The initial curriculum contained 58 learning objectives separated into 9 themes. In phase 1 31% (18/58) were accepted outright, 48% (28/58) were altered and 19% (11/58) were rejected. Two additional learning objectives were added. Of the 49 LOs included in phase 2, 98% (48/49) were accepted. The final curriculum was made up of 9 sub-themes and 48 LOs. CONCLUSION: Sport and Exercise Medicine is a broad ranging and rapidly growing speciality. It is important to establish SEM education in all levels of medical education, including undergraduate level. This is the first published version of a Delphi SEM curriculum for undergraduate medical teaching.

Physical fitness and diabetes.

Physical fitness is an essential part of, and an important means of, ensuring and maintaining good health. Exercise is a physical activity which is designed for improvement or maintenance of physical fitness. Pursuit for fitness should be an integral aspect of one's lifestyle, and hence one should engage in regular physical activity, exercises, games, sports and martial arts. Persons living with diabetes often find it challenging to pursue a proper exercise regimen in an effective, yet safe, manner. In this communication, we suggest a strategy to kick start a physical fitness regimen that one can adhere to. This simple suggestion will be helpful not only for persons living with diabetes and other chronic diseases, but for their health care providers as well.

Elastic tubes: the ideal equipment for telehealth exercise medicine in the management of prostate cancer?

Prostate cancer (PCa) affects 1 in 8 men, but exercise therapy has been shown to be a very effective intervention not only to induce physiological benefits but to also reduce the side effects of cancer treatments typically administered during PCa. The COVID19 pandemic has restricted access to exercise clinics, a problem which always existed for people living in rural and remote areas. This caused many exercise physiologists and researchers to transition their clinic-based exercise to online, home-based exercise. We would like to propose that researchers and exercise physiologists should consider the use of elastic tubes in both research and the clinical management of PCa, when exercise programs are administered remotely, as their characteristics make them an ideal exercise equipment. In this article, the characteristics, considerations, and information on quantifying exercise dosage when using elastic tubes in remote exercise delivery are discussed.

Exercise in preventing falls for men with prostate cancer: a modelled cost-utility analysis.

INTRODUCTION: Men who receive androgen deprivation therapy (ADT) for prostate cancer (PCa) are a vulnerable falls population due to the side effects of treatment. The purpose of this paper is to determine the cost-effectiveness of exercise in preventing falls and fractures for this high-risk population in Australia. METHODS: A decision analytic model was constructed to evaluate the cost utility of an exercise intervention compared to usual care from a health system perspective. The intervention comprised two 1-h sessions of supervised exercise per week over 1 year for men with non-metastatic PCa receiving curative radiation therapy and ADT. A Markov model simulated the transition between five health states: (1) at risk of falling; (2) at recurrent risk of falling; (3) fracture (minor or major); (4) non-fracture injury (minor or major); and (5) death. Model inputs including transition probabilities and utility scores were obtained from published meta-analyses, and costs were drawn from Australian data sources (e.g. Medical Benefits Schedule). The model time horizon was 3 years, and costs and effects were discounted at 5% annual rate. Costs and quality-adjusted life years (QALYs) were aggregated and compared between the intervention and control to calculate incremental net monetary benefit (iNMB). Uncertainty in the results was explored using deterministic and probabilistic sensitivity analyses (PSA). RESULTS: At a willingness-to-pay of AU$50,000 per QALY, the exercise intervention dominated, as it was less costly and more effective than usual care. The iNMB was $3010 per patient. The PSA showed a 58% probability the intervention was cost-effective. CONCLUSION: This is the first modelled economic evaluation of exercise for men with PCa. Our results suggest supervised exercise is cost-effective in reducing the risks of falls and fractures in this population.

Role of club doctors in the mental health management of Australian rules football players: a Delphi study.

Professional team athletes experience a range of mental health problems, both sports and non-sports related. However, there is limited information available for those charged with responsibility for managing these mental health conditions, particularly within the context of professional sporting clubs. This paper reports on consensus findings from a study of club doctors, who are primary care providers for professional team athletes within a specific code, the Australian Football League (AFL). Drawing on findings from a systematic literature search, a two-round Delphi procedure was used to develop a consensus on best practice for managing mental health conditions for club doctors as primary care providers for professional team athletes. Participants in this study were current and former club doctors employed in professional AFL clubs across Australia, with 28 doctors participating across two survey rounds. Overall, 77 statements were presented, with 50 endorsed as essential or important by ≥ 80% of the participants across the two rounds. Primary themes across nine domains include: (1) Prevention and Mental Health Promotion Activities; (2) Screening; (3) Engaging External Specialists; (4) Duty of Care; (5) Treatment: Assessment, Treatment and Case Coordination; (6) Communication; (7) Confidentiality; (8) Sleep Management and (9) Substance Use Management. This study is the first to offer club doctors working in professional team settings consensus guidelines for the management of mental health conditions, and the opportunity for greater clarification and consistency in role delivery.

Delphi developed syllabus for the medical specialty of sport and exercise medicine: part 2.

Training in the medical specialty of sport and exercise medicine (SEM) is available in many, but not all countries. In 2015, an independent Delphi group, the International Syllabus in Sport and Exercise Medicine Group (ISSEMG), was formed to create a basic syllabus for this medical specialty. The group provided the first part of this syllabus, by identifying 11 domains and a total of 80 general learning areas for the specialty, in December 2017. The next step in this process, and the aim of this paper was to determine the specific learning areas for each of the 80 general learning areas. A group of 26 physicians with a range of primary medical specialty qualifications including, Sport and Exercise Medicine, Family Medicine, Internal Medicine, Cardiology, Rheumatology and Anaesthetics were invited to participate in a multiple round online Delphi study to develop specific learning areas for each of the previously published general learning areas. All invitees have extensive clinical experience in the broader sports medicine field, and in one or more components of sports medicine governance at national and/or international level. SEM, Family Medicine, Internal Medicine, Cardiology, Rheumatology and Anaesthetics were invited to participate in a multiple round online Delphi study to develop specific learning areas for each of the previously published general learning areas. All invitees have extensive clinical experience in the broader sports medicine field, and in one or more components of sports medicine governance at national and/or international level. The hierarchical syllabus developed by the ISSEMG provides a useful resource in the planning, development and delivery of specialist training programmes in the medical specialty of SEM.

Injury epidemiology in professional ballet: a five-season prospective study of 1596 medical attention injuries and 543 time-loss injuries.

OBJECTIVES: To describe the incidence rate, severity, burden and aetiology of medical attention and time-loss injuries across five consecutive seasons at a professional ballet company. METHODS: Medical attention injuries, time-loss injuries and dance exposure hours of 123 professional ballet dancers (women: n=66, age: 28.0±8.3 years; men: n=57, age: 27.9±8.5 years) were prospectively recorded between the 2015/2016 and 2019/2020 seasons. RESULTS: The incidence rate (per 1000 hours) of medical attention injury was 3.9 (95% CI 3.3 to 4.4) for women and 3.1 (95% CI 2.6 to 3.5) for men. The incidence rate (per 1000 hours) of time-loss injury was 1.2 (95% CI 1.0 to 1.5) for women and 1.1 (95% CI 0.9 to 1.3) for men. First Soloists and Principals experienced between 2.0-2.2 additional medical attention injuries per 1000 hours and 0.9-1.1 additional time-loss injuries per 1000 hours compared with Apprentices (p≤0.025). Further, intraseason differences were observed in medical attention, but not time-loss, injury incidence rates with the highest incidence rates in early (August and September) and late (June) season months. Thirty-five per cent of time-loss injuries resulted in over 28 days of modified dance training. A greater percentage of time-loss injuries were classified as overuse (women: 50%; men: 51%) compared with traumatic (women: 40%; men: 41%). CONCLUSION: This is the first study to report the incidence rate of medical attention and time-loss injuries in professional ballet dancers. Incidence rates differed across company ranks and months, which may inform targeted injury prevention strategies.

Protecting the world's finest athletes: periodic health evaluation practices of the top performing National Olympic Committees from the 2016 Rio or 2018 PyeongChang Olympic Games.

AIM: To describe the periodic health evaluation (PHE) practices of the top performing National Olympic Committees (NOCs). METHODS: We sent a survey to NOCs finishing in the top 8 for medal count at the 2016 Rio Olympic Games or 2018 PyeongChang Olympic Games. The survey included four sections: (1) PHE staff composition and roles, (2) beliefs regarding the PHE, (3) a ranking of risk factors for future injury and (4) details on the elements of the PHE. RESULTS: All 14 NOCs with top 8 finishes at the 2016 Rio Olympic Games or 2018 PyeongChang Olympic Games completed the survey. NOCs included a median of seven staff specialties in the PHE, with physicians and physiotherapists having the highest level of involvement. There was agreement that PHEs are effective in identifying current health conditions (13/14) and that athletes should receive individualised action plans after their PHE (14/14), but less agreement (6/14) that PHEs can predict future injury. The practices of NOCs were diverse and often specific to the athlete population being tested, but always included the patient's health history, laboratory studies, cardiovascular screening and assessments of movement capacity. The top three risk factors for future injury were thought to be previous injury, age and training experience. CONCLUSIONS: Among the top performing NOCs, the PHE is a comprehensive, multidisciplinary process aimed to identify existing conditions and provide baseline health and performance profiles in the event of future injury. Research linking PHEs to injury prevention is needed.

Prevalence and frequency of menstrual cycle symptoms are associated with availability to train and compete: a study of 6812 exercising women recruited using the Strava exercise app.

OBJECTIVES: The menstrual cycle can affect sports participation and exercise performance. There are very few data on specific menstrual cycle symptoms (symptoms during various phases of the cycle, not only during menstruation) experienced by exercising women. We aimed to characterise the most common symptoms, as well as the number and frequency of symptoms, and evaluate whether menstrual cycle symptoms are associated with sporting outcomes. METHODS: 6812 adult women of reproductive age (mean age: 38.3 (8.7) years) who were not using combined hormonal contraception were recruited via the Strava exercise app user database and completed a 39-part survey. Respondents were from seven geographical areas, and the questions were translated and localised to each region (Brazil, n=892; France, n=1355; Germany, n=839; Spain, n=834; UK and Ireland, n=1350; and USA, n=1542). The survey captured exercise behaviours, current menstrual status, presence and frequency of menstrual cycle symptoms, medication use for symptoms, perceived effects of the menstrual cycle on exercise and work behaviours, and history of hormonal contraception use. We propose a novel Menstrual Symptom index (MSi) based on the presence and frequency of 18 commonly reported symptoms (range 0-54, where 54 would correspond to all 18 symptoms each occurring very frequently). RESULTS: The most prevalent menstrual cycle symptoms were mood changes/anxiety (90.6%), tiredness/fatigue (86.2%), stomach cramps (84.2%) and breast pain/tenderness (83.1%). After controlling for body mass index, training volume and age, the MSi was associated with a greater likelihood of missing or changing training (OR=1.09 (CI 1.08 to 1.10); p≤0.05), missing a sporting event/competition (OR=1.07 (CI 1.06 to 1.08); p≤0.05), absenteeism from work/academia (OR=1.08 (CI 1.07 to 1.09); p≤0.05) and use of pain medication (OR=1.09 (CI 1.08 to 1.09); p≤0.05). CONCLUSION: Menstrual cycle symptoms are very common in exercising women, and women report that these symptoms compromise their exercise participation and work capacity. The MSi needs to be formally validated (psychometrics); at present, it provides an easy way to quantify the frequency of menstrual cycle symptoms.

Recommendations for determining the validity of consumer wearable heart rate devices: expert statement and checklist of the INTERLIVE Network.

Assessing vital signs such as heart rate (HR) by wearable devices in a lifestyle-related environment provides widespread opportunities for public health related research and applications. Commonly, consumer wearable devices assessing HR are based on photoplethysmography (PPG), where HR is determined by absorption and reflection of emitted light by the blood. However, methodological differences and shortcomings in the validation process hamper the comparability of the validity of various wearable devices assessing HR. Towards Intelligent Health and Well-Being: Network of Physical Activity Assessment (INTERLIVE) is a joint European initiative of six universities and one industrial partner. The consortium was founded in 2019 and strives towards developing best-practice recommendations for evaluating the validity of consumer wearables and smartphones. This expert statement presents a best-practice validation protocol for consumer wearables assessing HR by PPG. The recommendations were developed through the following multi-stage process: (1) a systematic literature review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, (2) an unstructured review of the wider literature pertaining to factors that may introduce bias during the validation of these devices and (3) evidence-informed expert opinions of the INTERLIVE Network. A total of 44 articles were deemed eligible and retrieved through our systematic literature review. Based on these studies, a wider literature review and our evidence-informed expert opinions, we propose a validation framework with standardised recommendations using six domains: considerations for the target population, criterion measure, index measure, testing conditions, data processing and the statistical analysis. As such, this paper presents recommendations to standardise the validity testing and reporting of PPG-based HR wearables used by consumers. Moreover, checklists are provided to guide the validation protocol development and reporting. This will ensure that manufacturers, consumers, healthcare providers and researchers use wearables safely and to its full potential.

Para sport translation of the IOC consensus on recording and reporting of data for injury and illness in sport.

In 2020, the IOC proposed a universal methodology for the recording and reporting of data for injury and illness in sport. Para sport is played by individuals with impairment, and they have a unique set of considerations not captured by these recommendations. Therefore, the aim of this addendum to IOC consensus statement was to guide the Para sport researcher through the complexities and nuances that should be taken into consideration when collecting, registering, reporting and interpreting data regarding Para athlete health. To develop this translation, experts in the field of Para sports medicine and epidemiology conducted a formal consensus development process, which began in March 2020 with the formation of a consensus group that worked over eight phases, incorporating three virtual consensus meetings to finalise the translation. This translation is consistent with the IOC consensus statement, yet provides more detailed Para athlete specific definitions and recommendations on study population, specifically, diagnostic and eligible impairment categorisation and recording of adaptive equipment, and defining and classifying health problems in the context of Para sport. Additionally, recommendations and Para athlete specific examples are described with regards to injury mechanism, mode of onset, injury and illness classification, duration, capturing and reporting exposure and risk. Finally, methods and considerations are provided to cater to the varied needs of athletes with impairment with respect to data collection tools. This harmonisation will allow the science to develop and facilitate a more accurate understanding of injury and illness patterns for tailoring evidence-informed prevention programmes and enabling better planning of medical services for Para sport events.

A novel approach to improve detection of glucocorticoid doping in sport with new guidance for physicians prescribing for athletes.

The systemic effect of glucocorticoids (GCs) following injectable routes of administration presents a potential risk to both improving performance and causing harm to health in athletes. This review evaluates the current GC antidoping regulations defined by the World Anti-Doping Agency and presents a novel approach for defining permitted and prohibited use of glucocorticoids in sport based on the pharmacological potential for performance enhancement (PE) and risk of adverse effects on health. Known performance-enhancing doses of glucocorticoids are expressed in terms of cortisol-equivalent doses and thereby the dose associated with a high potential for PE for any GC and route of administration can be derived. Consequently, revised and substance-specific laboratory reporting values are presented to better distinguish between prohibited and permitted use in sport. In addition, washout periods are presented to enable clinicians to prescribe glucocorticoids safely and to avoid the risk of athletes testing positive for a doping test.

Development process of an evidence-based exercise program for post-operative colorectal cancer patients.

PURPOSE: Exercise is generally accepted to be beneficial for colorectal cancer patients; however, very few studies have investigated the effects of exercise on patient care and health outcomes during the immediate post-operative recovery period. Furthermore, very few studies have investigated the safety, feasibility, and efficacy of exercise on post-operative cancer patients. Although intervention programs should be based on solid evidence from clinical trials, the majority of previous studies have not presented the development process of the intervention programs. This paper describes a ten-step development process of an inpatient exercise program for colorectal cancer patients after colectomy. METHODS: The development process is composed of the following ten steps: systematic literature review, understanding patient characteristics via patient survey, first expert group discussion, development of the first draft exercise program, pretest, focus group interview, second expert group discussion, pilot study, randomized controlled trial, and the final exercise program development. RESULTS: The exercise program developed through the ten-step process was divided into three phases according to the patients' condition. For all three phases, patients performed the exercises two times a day, once under supervision. Any specific exercises that caused pain on a given day were excluded from the exercise program for that day. The exercise program reduced the length of hospital stay and time to flatus in colorectal cancer patients after surgery. CONCLUSION: This study reports a safe and effective means to develop an evidence-based exercise program not only for colorectal cancer patients but also for other population groups.

The role of exercise in the management of adverse effects of androgen deprivation therapy for prostate cancer: a rapid review.

PURPOSE: Prostate cancer (PCa) is the most commonly diagnosed cancer in Australia, accounting for one quarter of all new cancer diagnoses for males. Androgen deprivation therapy (ADT) is the standard first-line therapy for metastatic PCa but is also used across much of the spectrum of disease. Unfortunately, debilitating adverse effects are a significant and largely unavoidable feature of ADT. A recent systematic review of adverse effects of ADT identified 19 sub-groups classified according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0. The potential for multiple simultaneous adverse effects, their associated management and the impact of adverse effects on cancer outcomes and quality of life are important considerations in the treatment and supportive care of men with PCa. Exercise is increasingly being recognized as an efficacious strategy in managing these adverse effects. METHODS: A rapid review was undertaken to examine the role of exercise in the management of the most commonly reported ADT adverse effects classified according to the CTCAE sub-groups. A systematic search was conducted in Medline, PsycINFO, Google Scholar and Google for the years 2010 to September 2019 to identify the benefits of exercise in managing the adverse effects of ADT for PCa. RESULTS: There is strong evidence for exercise as medicine in addressing several of the adverse effects of PCa such as loss of muscle mass and strength, fatigue and declining physical function. Moderate level evidence for PCa exists for exercise-induced improvements in depression and anxiety, bone loss, and sexual dysfunction. While evidence of the effectiveness of exercise is lacking for many adverse effects of ADT for PCa, evidence in the cancer population as a whole or other clinical populations is strong, and many clinical guidelines recommend exercise as a fundamental part of their clinical management. With the exception of gynaecomastia and breast pain, there is increasing evidence (PCa, cancer or other clinical populations) to suggest that exercise has the potential to reduce and even prevent many of the adverse effects of ADT, thus improving survivorship outcomes for men with PCa. CONCLUSION: Exercise has the potential to reduce and even prevent many of the adverse effects of ADT, thus improving survivorship outcomes for men with PCa. The use of exercise for PCa management has the potential to translate into health and economic benefits in improved quality of life and fewer complications, resulting in savings to the health care system, enhanced productivity and reduced patient and carer burden. Exercise thus has the potential to improve quality of life for this population as well as generate significant cost savings.

Cognitive and neural effects of exercise following traumatic brain injury: A systematic review of randomized and controlled clinical trials.

Objective: Sub-maximal aerobic exercise can alleviate brain injury-related symptom burden. There is substantial data from animal studies and a growing clinical evidence base to suggest that exercise may also improve cognitive and neural outcomes following brain injury. We performed this systematic review to consolidate evidence from randomized and controlled clinical trials on the effects of exercise on cognitive and neuroimaging outcomes following brain injury in humans.Design: Systematic review.Data sources: MEDLINE, EMBASE, PsychINFO, CINAHL, SPORTDiscus, and Cochrane Central Database.Eligibility criteria for screening studies: Randomized or controlled clinical trials examining the effects of exercise on cognitive and/or neuroimaging outcomes in traumatic brain injury. No restriction was placed on age (or other demographic variables) or severity of injury.Results: Six studies (with an average sample of 42 participants) met eligibility criteria. Three studies used neuroimaging and reported exercise-related improvements as measured by either functional or diffusion-based imaging. The remainder of the trials that employed cognitive outcomes reported largely null findings.Summary/Conclusion: This review demonstrates that exercise shows promise (primarily with respect to neuroimaging outcomes) as a brain injury intervention. While the field is young and heterogeneity between studies precludes meta-analysis, this review raises important questions that need to be addressed by future trials.

Comparative effectiveness of treatments for patellofemoral pain: a living systematic review with network meta-analysis.

OBJECTIVE: To investigate the comparative effectiveness of all treatments for patellofemoral pain (PFP). DESIGN: Living systematic review with network meta-analysis (NMA). DATA SOURCES: Sensitive search in seven databases, three grey literature resources and four trial registers. ELIGIBILITY CRITERIA: Randomised controlled trials evaluating any treatment for PFP with outcomes 'any improvement', and pain intensity. DATA EXTRACTION: Two reviewers independently extracted data and assessed risk of bias with Risk of Bias Tool V.2. We used Grading of Recommendations, Assessment, Development and Evaluation to appraise the strength of the evidence. PRIMARY OUTCOME MEASURE: 'Any improvement' measured with a Global Rating of Change Scale. RESULTS: Twenty-two trials (with forty-eight treatment arms) were included, of which approximately 10 (45%) were at high risk of bias for the primary outcome. Most comparisons had a low to very low strength of the evidence. All treatments were better than wait and see for any improvement at 3 months (education (OR 9.6, 95% credible interval (CrI): 2.2 to 48.8); exercise (OR 13.0, 95% CrI: 2.4 to 83.5); education+orthosis (OR 16.5, 95% CrI: 4.9 to 65.8); education+exercise+patellar taping/mobilisations (OR 25.2, 95% CrI: 5.7 to 130.3) and education+exercise+patellar taping/mobilisations+orthosis (OR 38.8, 95% CrI: 7.3 to 236.9)). Education+exercise+patellar taping/mobilisations, with (OR 4.0, 95% CrI: 1.5 to 11.8) or without orthosis (OR 2.6, 95% CrI: 1.7 to 4.2), were superior to education alone. At 12 months, education or education+any combination yielded similar improvement rates. SUMMARY/CONCLUSION: Education combined with a physical treatment (exercise, orthoses or patellar taping/mobilisation) is most likely to be effective at 3 months. At 12 months, education appears comparable to education with a physical treatment. There was insufficient evidence to recommend a specific type of physical treatment over another. All treatments in our NMA were superior to wait and see at 3 months, and we recommend avoiding a wait-and-see approach. PROSPERO REGISTERATION NUMBER: PROSPERO registration CRD42018079502.

Developing common demographic data elements to include in future editions of the SCAT and Child SCAT: a modified international Delphi study.

BACKGROUND: The Sport Concussion Assessment Tool (SCAT) and Child SCAT are the 'gold standard' assessment tools for a suspected sport-related concussion (SRC). A number of 'modifiers' (eg, previous history of concussion) of a SRC have been identified. These may influence how the SCAT/Child SCAT results should be interpreted. OBJECTIVES: To achieve consensus, via an international panel of SRC experts, on which athlete/player and parent/caregiver demographic variables should be considered for inclusion in future editions of the SCAT/Child SCAT respectively. METHODS: A two-round modified Delphi technique, overseen by a steering committee, invited 41 panellists to achieve expert consensus (≥80% agreement). The first round utilised open questions to generate demographic variables; the second round used a five-point ordinal item to rank the importance of including each variable in future editions of the SCAT/Child SCAT. RESULTS: 15 experts participated in at least one Delphi round. 29 athlete/player and eight parent/caregiver variables reached consensus for inclusion in the SCAT, whereas two parent/caregiver variables reached consensus for exclusion. 28 athlete/player and four parent/caregiver variables reached consensus for the Child SCAT, whereas two parent/caregiver variables reached consensus for exclusion. Key categories of variables included the following: concussion/sport details, personal medical conditions and family medical history. CONCLUSION: This study provides a list of athlete/player and parent/caregiver demographic variables that should be considered in future revisions of the SCAT/Child SCAT. By considering (and ultimately likely including) a wider and standard set of additional demographic variables, the Concussion in Sport experts will be able to provide clinicians and researchers with data that may enhance interpretation of the individual's data and the building of larger datasets.

Remote assessment in sport and exercise medicine (SEM): a narrative review and teleSEM solutions for and beyond the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic forces sport and exercise medicine (SEM) physicians to think differently about the clinical care of patients. Many rapidly implement eHealth and telemedicine solutions specific to SEM without guidance on how best to provide these services. AIM: The aim of this paper is to present some guiding principles on how to plan for and perform an SEM consultation remotely (teleSEM) based on a narrative review of the literature. A secondary aim is to develop a generic teleSEM injury template. RESULTS: eHealth and telemedicine are essential solutions to effective remote patient care, also in SEM. This paper provides guidance for wise planning and delivery of teleSEM. It is crucial for SEM physicians, technology providers and organisations to codesign teleSEM services, ideally involving athletes, coaches and other clinicians involved in the clinical care of athletes, and to gradually implement these services with appropriate support and education. CONCLUSION: teleSEM provides solutions for remote athlete clinical care during and after the COVID-19 pandemic. We define two new terms-eSEM and teleSEM and discuss guiding principles on how to plan for and perform SEM consultations remotely (teleSEM). We provide an example of a generic teleSEM injury assessment guide.

Complete resolution of a hamstring intramuscular tendon injury on MRI is not necessary for a clinically successful return to play.

BACKGROUND: Clinical decision-making around intramuscular tendon injuries of the hamstrings is a controversial topic in sports medicine. For this injury, MRI at return to play (RTP) might improve RTP decision-making; however, no studies have investigated this. OBJECTIVE: Our objectives were to describe MRI characteristics at RTP, to evaluate healing and to examine the association of MRI characteristics at RTP with reinjury for clinically recovered hamstring intramuscular tendon injuries. METHODS: We included 41 athletes with hamstring intramuscular tendon injuries and an MRI at baseline and RTP. For both MRIs, we used a standardised scoring form that included intramuscular tendon injury characteristics. We recorded reinjuries during 1-year follow-up. RESULTS: At RTP, 56% of the intramuscular tendons showed a partial or complete thickness tendon discontinuity. Regarding healing from injury to RTP, 18 of 34 (44% overall) partial-thickness tendon discontinuities became continuous and 6 out of 7 (15% overall) complete thickness tendon discontinuities became partial-thickness tendon discontinuities. Waviness decreased from 61% to 12%, and 88% of tendons became thickened. We recorded eight (20%) reinjuries within 1 year. Intramuscular tendon characteristics at RTP between participants with or without a reinjury were similar. CONCLUSION: Complete resolution of an intramuscular tendon injury on MRI is not necessary for clinically successful RTP. From injury to RTP, the intramuscular tendon displayed signs of healing. Intramuscular tendon characteristics of those with or without a reinjury were similar.
