Comparison of Subjective and Biomechanical Outcomes Between Proprioceptive Training and Modified Broström-Gould Surgery for Chronic Ankle Instability: A Randomized Controlled Trial.

研究概要

Fifty-six patients with chronic ankle instability were randomized to receive either proprioceptive training (n=28) or modified Broström-Gould surgery (n=28). The primary outcome was the Foot and Ankle Ability Measure (FAAM) Sports subscale score. Secondary outcomes included biomechanical measures such as foot pressure during walking, center of pressure (COP) velocity, and time-to-boundary (TTB) during single-leg standing. Outcomes were evaluated at baseline and at 3, 6, and 12 months post-intervention. Overall, the results showed that proprioceptive training facilitated earlier recovery of sports function and medial-lateral stability, while surgery yielded more persistent biomechanical improvements. These findings suggest tailored treatment strategies based on recovery timelines and patient goals.
