Overview
Brief Summary
There is evidence to support individuals with chronic ankle instability (CAI) have altered gait biomechanics which may lead to re-injury and poor patient outcomes. Currently, there are no interventions specifically targeting these abnormal gait biomechanics. Evidence supports the use of an external focus of attention feedback to promote motor learning and retention. The overall purpose of randomized clinical trial is to determine the effects of a 2-week (8 session) gait retraining protocol using an auditory external feedback instrument can (1) alter biomechanics during functional tasks (walking, step-down, lunge, lateral hops, and balance) (2) improve ankle cartilage measures and (3) improve patient-reported outcome measures.

Outcomes
Primary Outcomes
Changes from baseline in talar cartilage deformation before and after walking
Time Frame: Immediate post-intervention, 1-week post-intervention
Talar cartilage thickness and cross-sectional area will be measured with an diagnostic ultrasound imaging system
Changes from baseline in self-reported ankle function
Time Frame: Immediate post-intervention, 1-week post-intervention
Changes from baseline in self-reported function as measured by the Foot and Ankle Ability Measure (FAAM) Activities of Daily Living and Sport questionnaire. Scores range from 100% (no decrease in function) to 0% (complete loss of function).
Changes from baseline in lower extremity kinetics during walking
Time Frame: Immediate post-intervention, 1-week post-intervention
Plantar pressure and center of pressure trajectory measured with an in-shoe plantar pressure system
Secondary Outcomes
- Changes from baseline in static balance(Immediate post-intervention, 1-week post-intervention)
- 2. Changes from baseline in plantar pressure during forward lunges, lateral hops, and a step-down(Immediate post-intervention, 1-week post-intervention)
