CAI often results in impaired sensorimotor control, leading to altered gait strategies such as slower walking speed, shorter step length, and increased visual reliance. Stroboscopic glasses intermittently restrict visual input, potentially reducing visual dependence and enhancing proprioceptive feedback.\n\nParticipants will complete walking trials under three randomized visual conditions: high-frequency stroboscopic, low-frequency stroboscopic, and no-glasses control. Gait parameters will be measured using the GAITRite system, and surface electromyography (sEMG) will record activation of the tibialis anterior, peroneus longus, and gastrocnemius muscles. Findings may provide insight into sensorimotor adaptation mechanisms and inform rehabilitation strategies to improve functional stability in individuals with CAI.",[67],"Chronic Ankle Instability",[69,70,71,72],"Stroboscopic Glasses","Stroboscopic Vision","Gait Analysis","Surface Electromyography","NOT_YET_RECRUITING","2025-08-14",{"date":76,"type":77},"2025-08-21","ACTUAL",{"date":79,"type":61},"2025-08-31",{"date":81,"type":61},"2025-10-12",{"name":5,"class":6},1]
