This study aims to determine and assess the prevalence of chronic ankle instability (CAI) in Chinese dancers and correlate the impact of CAI with foot function.Methods This is a cross-sectional study of 105 Chinese dancers. CAI was assessed using the Cumberland Ankle Instability Tool and foot function via the Foot and Ankle Outcome Score (FAOS). Both self-reported assessment tools were distributed online between January and February 2021. Subjects were divided into CAI and healthy groups to observe any correlations in demographics, training hours and foot function.Results CAI was seen in 28% of Chinese dancers, with most being unilateral instability. The number of training hours, level of expertise, occupation, gender and age showed no statistical significance with CAI. The FAOS showed that subjects with CAI had significantly greater pain and poorer quality of life.Discussion and conclusion CAI is a problem affecting 28% of performers of Chinese dance. Future research should investigate the ankle biomechanics in Chinese dance and specific risk factors for CAI to formulate strategies to prevent ankle injuries in Chinese dancers.All data relevant to the study are included in the article or uploaded as online supplemental information.
