Comparison of the Effects of Hip and Ankle Focused Progressive Exercise Training on Lower Extremity Function in Athletes With Chronic Ankle Instability

Sponsor: Hacettepe University

Summary

Chronic ankle instability refers to a combination of persistent mechanical and functional instability symptoms following an ankle sprain. Along with these symptoms, decreased proprioception, reduced neuromuscular control, poor postural control, limited dorsiflexion range of motion, decreased ankle strength, and altered lower-extremity biomechanics during functional activities are also observed. In addition, individuals with chronic ankle instability have been shown to exhibit limitations in energy transfer across the lower extremity. These symptoms may hinder patients' physical activity levels and athletic performance and negatively affect their quality of life. Since the lower extremity functions as a unit, changes in adaptive strategies at the ankle can lead to kinematic alterations in proximal joints. Although the instability originates at the ankle, higher-level joints are also affected, and it has even been reported that in this population, lower-extremity stability is primarily achieved through the hip joint. While the effectiveness of hip-focused exercises has begun to be investigated in the literature, the superiority of different muscle groups has not yet been compared.
