Abstract:
ObjectiveTo investigate the immediate effect of wearing a soft ankle brace on dynamic and static balance function and biomechanics of affected lower limbs during walking in chronic ankle instability (CAI) patients. MethodsFrom January to August, 2021, 40 CAI patients from Musculoskeletal Rehabilitation Center, Beijing Rehabilitation Hospital, Capital Medical University were measured dynamic and static balance indexes with Zebris FDM-System and Y balance test, before and after wearing a soft ankle brace; while the kinetics indexes and surface electromyography of the affected lower extremities during walking were collected with Zebris FDM-System and a surface electromyography telemeter simultaneously. ResultsThe velocity and area of center of pressure reduced in both open and closed eye modes (|t| > 2.876, P < 0.01), the Y-balance scores increased in all the directions (|t| > 21.212, P < 0.001) after wearing brace; while the peak pressures and impulses increased in the midfoot and medial forefoot regions (|t| > 2.057, P < 0.05), and decreased in the lateral heel, lateral forefoot and toe regions (|t| > 2.464, P < 0.05), and the root mean square of surface electromyography increased in the tibialis anterior and lateral gastrocnemius (|t| > 2.159, P < 0.05) during walking. ConclusionWearing soft brace can immediately improve dynamic and static balance of CAI patients, and optimize plantar kinetic distribution and enhance activation of the anterior tibial and the lateral head of gastrocnemius of the affected limb during walking, to improve motor control of CAI patients.
