Effects of Rigid and Kinesio Taping on Balance and Performance in Chronic Ankle Instability

The goal of this clinical trial is to evaluate the immediate effects of rigid subtalar sling taping, kinesio subtalar sling taping, and sham taping on balance, proprioception, ankle mobility, and functional performance in physically active adults with chronic ankle instability. The main questions it aims to answer are: * Does rigid subtalar sling taping improve dynamic balance, ankle proprioception, ankle dorsiflexion mobility, and functional performance in individuals with chronic ankle instability? * Does rigid subtalar sling taping provide greater benefits than kinesio subtalar sling taping or sham taping under fatigue and recovery conditions? Researchers will compare rigid subtalar sling taping, kinesio subtalar sling taping, and sham taping to determine their effects on balance, proprioception, ankle mobility, and functional performance before fatigue, after fatigue, and following recovery. Participants will: * Complete baseline assessments of dynamic balance, ankle proprioception, ankle dorsiflexion mobility, and functional performance. * Be randomly assigned to receive rigid subtalar sling taping, kinesio subtalar sling taping, or sham taping. * Repeat all outcome assessments immediately after tape application. * Perform a standardized fatigue protocol consisting of running, hopping, jumping, and heel-raise exercises until predefined fatigue criteria are reached. * Complete all outcome assessments immediately after the fatigue protocol. * Rest in a seated position for 20 minutes. * Complete a final set of outcome assessments following recovery. The study aims to identify whether subtalar sling taping can improve functional performance and neuromuscular control in physically active individuals with chronic ankle instability and whether these effects are maintained after fatigue and recovery.
