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 ▲]

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.

INTRODUCTION: The occurrence of exercise-induced muscle damage (EIMD) can affect the running pattern and endurance performance. However, the EIMD-induced changes in biomechanical and physiologic parameters remain poorly understood. The aim of this study was to examine the effects of a single isokinetic eccentric (ECC) exercise and ensuing DOMS on running biomechanics, physiologic measures and muscle activity during an endurance exercise performed 48h later. METHODS: Twelve healthy , moderately active adult men completed two treadmill running tests (at 85% Maximal aerobic speed) until exhaustion, with a week interval between both tests. Participants were submitted to a bilateral isokinetic eccentric protocol on the knee extensors 48hours before the second test. The subject’s running kinematics (using a 3D motion system), heart rate, ventilation, pulmonary gas exchange and muscle activity were continuously recorded during the running tests. Delayed-Onset Muscle Soreness, plasma creatine kinase, muscle extensibility, muscle function were assessed before and 48h after the ECC exercise. RESULTS: In presence of EIMD, the running time to exhaustion was shorter (p<0.05) while the Borg rate of perceived exertion was higher (p<0.01). Muscle force and vertical jump performance were also reduced with EIMD. The physiological data showed no significant difference between both endurance tests, except for the lactate level and heart rate measured at the end of the test which appeared significantly higher with EIMD (p<0.05). In contrast, the 3D analysis revealed a significant decrease in stride length and a significant increase in stride frequency and stance phase with DOMS. Articular amplitudes and electromyography data showed no significant change although some trends are noteworthy, such as increased muscle activity. CONCLUSION: Our data suggest that the presence of knee extensors EIMD altered the running biomechanics and endurance performance without significative changes of the physiological parameters. Further investigations are required to explore whether the EIMD-induced biomechanical modifications are the result of pain perception or impaired muscle function. [less ▲]

High performance sport has always had a considerable impact on the musculoskeletal system but also on the whole body of athletes. The main structures concerned are the bones, muscles, joints but also the endocrine system. The impact on these has been analyzed and to better understand the bio-physiological phenomena brought about by sport. We also emphasized the risks and the means of prevention concerning certain osteo-articular and muscular lesions. The influence of sports activity on hormones such as testosterone, growth hormone and cortisol has been developed, whether under stress or at rest. Finally, a paragraph was devoted to the use of doping products, the desired effects but also the risks generated. [less ▲]

Over the last decade, Physical and Rehabilitation Medicine (PRM) is a medical specialty that has evolved considerably in the various fields that concern it : from the management of low back pain and lumbosciatalgia or osteoporosis in a multidisciplinary manner, through the use of new technologies in neuro-locomotor rehabilitation and robotisation in amputee patients for example, the development of regenerative medicine and prevention in sports traumatology and, finally, the progress of electrophysiology techniques for the diagnosis of small-fibre neuropathies. These various advances will be discussed in this article. [less ▲]

Background: Transcranial Direct Current Stimulation has been increasing in popularity in the last few years. Despite vast amounts of articles on the use of tDCS on stroke patients, very little has been done during the acute phase. Objectives: Measure the effects of tDCS on functional and sensory outcomes throughout the first year post onset of stroke. Methods: 50 acute stroke patients were randomized and placed into either the treatment or sham group. Anodal tDCS was applied (2 mA, 20min) 5 times a week during the first month post stroke. Patients were evaluated with the Wolf Motor Function Test, the Semmes Weinstein Monofilament Test, the Upper Extremity section (UEFM), the Lower Extremity section (LEFM) and the Somatosensory section of the Fugl Meyer Test, the Tardieu Spasticity Scale, the Stroke Impact Scale (SIS), the Hospital Anxiety and Depression Scale (HADS) and the Barthel Index. Evaluations were held at 48 h post stroke, week 1, 2, 3, 4, 3 months, 6 months and 1 year. Results: There were statistically and clinically significant improvements after tDCS in all functional motor outcomes, and somatosensory functions. Differences between both groups for the main outcome (WMFT time) were 51% (p=0.04) at one month, and 57% (p=0.02) at one year. Conclusion: tDCS seems to be an effective adjuvant to conventional rehabilitation techniques. If applied in the acute stages of stroke, functional recovery is not only accelerated, but improved, and results are maintained up to one-year post stroke. [less ▲]

Introduction: After a first lateral ankle sprain, ankle proprioception may often be altered and contribute to a high risk of re-injury. The joint position reproduction (JPR) test enable to evaluate a joint proprioception. Isokinetic dynamometer is a reliable tool to assess the JPR ability. However, this tool is expensive and not always adapted to assessment on field. This study aimed to establish the reliability of ipsilateral JPR as used in clinical practice with a commercialized destabilization device (Myolux®). Material & Methods: fifteen recreationally-active young adults (30 ankles) were assessed by the same clinician twice, six to eight days apart. Measurements were performed with subjects in a sitting position. The participants were wearing the Myolux®. This device allowed a movement from 5° of eversion to 30° of inversion. After familiarization, the test consisted of ten repetitions of ipsilateral JPR imposed randomly by the connected tablet. The subjects started with a score of 100%. They lost 5% when they made a mistake between 2° to 4°; they lost 10% when they made a mistake higher than 4°. Test-retest intra-class correlation coefficients (ICC) and minimal detectable change (MDC) were calculated to determine the reliability of the device. Results: ICC was equal to 0.12 [-0.40;0.58] with MDC equal to 33% on the dominant leg and ICC was equal to 0.0 [-0.50;0.50] with MDC equal to 52% on the non-dominant leg. Conclusion: Up to now, Myolux® is not developed enough to be used as an ankle proprioception (JPR) evaluation tool in clinical practice. [less ▲]

Inertial measurement units (IMUs) are now considered as an economical solution for long term assessment in real conditions. However, their use in running gait analysis is relatively new and limited. Detecting the timing at which the foot strikes the ground (initial contact, IC) and the timing at which the foot leaves the ground (terminal contact, TC) gives access to many relevant temporal parameters such as stance, swing or stride durations. In this paper, we present an original algorithm to extract IC and TC timings and associated parameters from running data. These data have been measured using a newly developed IMU-based hardware system in ten asymptotic participants who ran at three speeds (slow, normal, and fast) with different running patterns (natural, rearfoot strike, mid-foot strike, and forefoot strike). This algorithm has been validated against a 200 Hz video camera based on 7056 IC and TC timings and 6861 temporal parameters. This algorithm extracted ICs and TCs with an accuracy and precision of (median [1st quartile; 3rd quartile]) 5 ms [-5 ms, 15 ms] and 0 ms [-5 ms, 5 ms], respectively. The relative errors in the extraction of stride and stance durations are -1.56 ± 3.00% and 0.00 ± 1.32%, respectively. [less ▲]
