- Abstract
Purpose: Chronic ankle instability is characterized by repeated ankle sprains. Peroneal muscles are important for control of the ankle and have been evaluated using electromyographic analyses, but there has been lack of study about any relationship between the peroneal muscle structure and self-reported function after ankle sprains. Therefore, this study aimed to investigate the relationship between self-reported functional stability and peroneal muscle structure in chronic ankle instability. Methods: Thirty subjects aged between 18-45 years and reporting chronic ankle instability were evaluated. Participants completed the Cumberland Ankle Instability Tool questionnaire to determine ankle stability experience. Structural analysis of the peroneal muscles was performed using musculoskeletal ultrasound scanning. Cross sectional area and thickness of peroneal longus and brevis were scanned. Results: The mean Cumberland Ankle Instability Tool score of subjects was 15.40±6.23. A statistically significant positive moderate correlation was found between stability scores and total cross-sectional area of peroneal muscles (r=0.405, p=0.027). In another words; subjects with higher levels of self-reported ankle stability had larger peroneal cross-sectional area. Conclusion: The subjects with chronic ankle instability who had larger peroneal cross-sectional area may have greater peroneal strength. Thereafter, this group may have better ankle stability than those with perceived low ankle stability. This potential for a structural relationship associated with improved stability may be relevant to physiotherapists and rehabilitation programmes. Further research may focus on other muscular structures around the ankle joint in chronic ankle instability.
