| Objective: To investigate the influence of ankle function and gait kinematics characteristics on quality of life in patients with functional ankle instability (FAI), and to analyze the predictors of quality of life. Methods: This was a single-center cross-sectional study involving 90 patients with FAI. The information was collected by questionnaire survey, and the kinematic parameters were collected by 3D gait analysis system. Finally, the predictive factors were screened by correlation analysis and multiple linear regression model. Results: Age (r=-0.453, P=0.000), body mass index (BMI) (r=-0.370,P=0.001), standing phase (r=-0.364,P=0.000), legs supporting phase (r=-0.367,P=0.000), pelvic rotation gait variable scores (GVS) (r=-0.319,P=0.002), ankle dorsiflexion GVS (r=-0.318,P=0.002) were negatively correlated with quality of life. Further regression analysis showed that gait speed, CAIT, BMI, pelvic rotation GVS and ankle dorsiflexion plantar flexion GVS were important predictors of quality of life in patients with FAI (F=18.139,R2=0.52,P=0.000). Conclusion: Gait speed, CAIT, BMI and gait variation parameters are the key predictors of FAI quality of life, suggesting that attention should be paid to comprehensive intervention strategies in clinical practice. |
