Background: Recommendations are available for assessment criteria for safe return-to-play (RTP) after a lateral ankle sprain. However, their current use among physicians is unknown. Methods: French-speaking physicians in Belgium, France and Switzerland were asked to complete an online survey and report their clinical assessment of selected RTP criteria. Results:The respondent sample (n = 109) included physicians with and without Sports Medicine education, varied level of experience and proportion of athletes in their practice population. Pain was the most selected criterion for safe RTP (90% of physicians), followed by ability to engage in functional tasks (82%), functional instability (73%), range of motion (61%), proprioception (47%), mechanical instability (39%), strength (38%) and swelling (31%). A low proportion of physicians use quantitative measures to assess these criteria (between 4% and 53%). Conclusions: A large proportion of physicians consider the recommended criteria for RTP decisions. However, physicians do not frequently use quantitative measures. [less ▲]

In regular times, implementing exercise-based injury prevention programs into the training routine of high-level and professional athletes represents a key and challenging aspect to decrease injury risk. Barriers to implementing such prevention programs have previously been identified such as lack of resources, logistic issues or motivation. The COVID-19 pandemic associated with restrictions on daily life dramatically impacted sports participation from training to competition. It is therefore reasonable to assume that such lockdown-like context has exacerbated the challenge to implement exercise-based injury prevention programs, potentially leading to a greater musculoskeletal injury risk. In this narrative review, recommendations are proposed for building an expertise- and evidence-based Standard Operating Procedure for injury prevention in lockdown-like contexts for high-level and professional athletes. The following recommendations can be provided: (1) assess the global and sport-specific risks in the light of the ongoing cause of isolation; (2) adapt remote training materials and programs; (3) ensure regular quality communication within the staff, between athletes and the staff as well as between athletes; (4) follow the athlete's mental well-being; and (5) plan for a safe return-to-sports as well as for an ongoing monitoring of the load-recovery balance. These key domains should further be addressed to comply with local policies, which are subject to change over time in each individual country. The use of these recommendations may improve the readiness of athletes, coaches, physicians and all sports stakeholders for future lockdown-like contexts. [less ▲]

INTRODUCTION: After a Musculo-skeletal injury, monitoring rehabilitation could help practitioners to objectify improvement and to decide how to adapt their treatment. Muscle strength is one essential component of rehabilitation in general. One – Repetition Maximal (1-RM) is a reliable measure that helps practitioners to quantitatively assess muscle strength (Grgic et al., 2020). A large majority of muscles could be assessed with 1-RM, however we do not know if the assessment of ankle muscle strength could be assessed using 1-RM in reliable way. The aim of this study was to determine the level of Intrarater agreement of ankle 1-RM. METHODS: Twenty-fou r healthy young adults (10 women and 14 men) volunteered to participate in this study. One – Repetition maximal of ankle evertors, invertors and dorsiflexors were measured with participants lying supine with the calf of tested ankle on a step (knee flexed approximately to 30-40°) and a complete flexion of the other leg. The measurement were performed over one week by the same assessor on the same vertical pulley. Intrarater reliability was determined using the intra-class correlation coefficient (ICC) and the measurement error was determine using the standard errors of measurement (SEM) minimal detectable change (MDC). RESULTS: Intrarater reliability in healthy women for inversion, eversion and dorsiflexion 1-RM was good to excellent (ICC=0.69–0.95) with relatively low measurement errors (SEM=1.31 - 1.84 and MDC=3.62-5.10). Intrarater reliability in healthy men for inversion, eversion and dorsiflexion 1-RM was fair to excellent (ICC=0.54–0.84) with relatively low measurement errors (SEM=2.94 - 4.45 and MDC=8.14 – 12.3). CONCLUSION: The assessment of ankle evertors, investors and dorsiflexors 1-RM is reliable in healthy young adults. This results has to be studied on injured adults but it is a promising method easy to use in rehabilitation after ankle injury. Reference: Grgic, J., Lazinica, B., Schoenfeld, B. J., & Pedisic, Z.

BACKGROUND: Isokinetic evaluation is considered the gold standard in muscle strength measurement due to its sensitivity, intra-dynamometer reproducibility and usefulness in the injury prevention screening and follow up of subjects with musculoskeletal pathologies, neurological disease or after surgical operation. However, can one switch among different isokinetic dynamometers for the purpose of knee muscles evaluation? OBJECTIVES: To comprehensively evaluate the compatibility of the isokinetic short concentric and eccentric strength evaluation protocol and of the fatigability resistance evaluation between three different isokinetic devices. METHODS: Eighteen recreationally active men underwent three isokinetic knee testing sessions on three different isokinetic devices with 7–10 days of rest between each session. Relative (Pearson’s r product-moment correlation coefficient – PCC) and absolute (standard error of measurement – SEM, Cohen effect sizes (d) and probabilistic inferences – MBI) parameters of reproducibility were determined to assess the inter-dynamometer agreement. RESULTS: For the short concentric and eccentric strength evaluation protocol, the extensors in concentric mode and the flexors in eccentric mode can be compared (eventually with transposition formulas provided) between Biodex, Con-Trex and Cybex (almost all PCC  0.80). The DCR could be compared between Con-Trex and Cybex and between Biodex and Cybex pairs (eventually with transposition formula provided). For the fatigability resistance evaluation protocol, the total sum can be compared for extensors (eventually with transposition formulas provided) for PM for all dynamometer pairs considered and, in the case of MW, only for Biodex and Con-Trex (PCC  0.80). CONCLUSIONS: Only some of the parameters derived either from the short concentric and eccentric strength evaluation protocol or the fatigability resistance evaluation protocol may be interchangeable providing transposition formulas are applied. Otherwise, isokinetic findings are largely system-dependent save some specific instances. [less ▲]

The Wingate Anaerobic Test (WAnT) and isokinetic fatigability protocols are mainly used to evaluate the anaerobic power of athletes for whom jumping is a predominant action in their sport. Nevertheless, the testing protocol must be as close as possible to the activity pattern of the sport to be valid. Therefore, for these athletes, the test should consist of repetitions of jumps that are task-specific. Our aim was to propose a new jumping protocol allowing for specific assessment of fatigue, to examine its absolute and relative reliability and to determine its ideal duration. Twenty male volleyball performed fifty countermovement jumps (CMJ) at a rate of 33 jumps per minute on two occasions, with seven days recovery between each session. Jump height was computed for each CMJ using a 3D optoelectronic system, which was subsequently added to determine cumulative performance after 10, 15, 20, 25, 30, 35, 40, 45 and 50 repetitions. Reliability of the average jump height was not affected by the lengthening of the protocol and was high for all considered durations (ICC > 0.94; SEM < 5%). A decrease in performance was directly and proportionally related to the duration of the fatigability protocol. Measuring average jump height during a protocol involving 25 CMJ at the rate of 33 jumps per minute appears to represent the best compromise between reliability, induced fatigue and physiological considerations. Moreover, until 25 repetitions, the partial sums by five repetitions can and should be used to further explore the subject's performance during the test. [less ▲]

Goalkeepers are important players in a soccer team. Their purpose is to not take a goal. They are the only ones authorized to grab the ball with their hands. They have different physical characteristics and abilities from other players. They cover approximately half of the distance of the outfield players. They have few decisive actions (2 to 10) but it is at a high intensity (jumps, dives, sprints). Goalkeepers are different players, so they are exposed to different types of injuries. The incidence of injury is lesser than other, 4,6 per 1000 hours of soccer exposure against 8 for the out fields players. Injuries in the upper extremity are 5 times more frequent in goalkeepers than other, with longer days of absence. Appropriate training combined with specific prevention programs should contribute to the reduction of injuries and the optimization of their soccer potential. [less ▲]

Background : Lateral ankle sprain is the most common ankle injury. Fatigue seems to play a role in this injury as it is at the end of a match (soccer or rugby) that ankle sprains occur most often. The objective of this study was to evaluate the reproducibility of a fatigue resistance test and to analyze the differences in the scores obtained according to the characteristics of our population. Material & Method: We recruited 40 active volunteers (25 men, 15 women, 23.2±2.7 years) with or without a history of sprains. They performed a unipodal support fatigue test with a Myolux® destabilization tool. The subjects had to perform a maximum number of repetitions of slow inversion and fast eversion. This test was performed twice at one week intervals. Subcategories were formed in our population. Results: The relative reproducibility was good ICC =0.80 [0.69-0.88] but the measurement error was relatively high (SEM=4.85 and MDC :13.5). A significant difference emerged between the healthy subjects who were statistically significantly better than the chronically unstable subjects (p<0.02). Conclusion: The muscle fatigue test with the Myolux® tool is reproducible. The number of repetitions of the inversion/eversion movement seems to be lower in subjects with chronic ankle instability, however to objectify an improvement or a difference between patients a difference of 14 repetitions is necessary.
