Abstract

Background: There are quite a few studies that compare 2 or 3 groups of subjects related to ankle sprain. But there are no studies comparing the four groups: healthy subjects (HEA), subjects with ankle sprains (LAS), subjects with ankle sprains but who are recovered (COPERS) and subjects with chronic ankle instability (CAI). Therefore, this study aimed to fill the gaps in the literature and would allow us to emphasize the biomechanical alterations existing in these participants, compare them, and then direct therapists towards an effective therapy, potentially lowering the likelihood of sprain recurrence in runners. Objectives: To report gait analysis, i.e., walking and running, between runners with different clinical history of ankle sprain, i.e., healthy, copers, chronic ankle instability and recent ankle sprain. Study design: Cross-sectional cohort study. Method: Participants completed three questionnaires from June to September 2023. Eligible participants were enrolled and assigned to their corresponding category, based on these eligibility criteria i.e., HEA, COPERS, LAS or CAI. To be included, all participants had to be active runners. Each runner underwent a complete clinical examination of the ankles as well as an analysis of the running biomechanics. Results: Significantly reduced mechanical work recovery and reduced step duration were reported for the participant with recent history of ankle sprain during the walking. There were no significant differences of running biomechanics between groups. Conclusion: Ankle sprain could alter walking gait compared to healthy individual without affecting running.
