- University of North Carolina, Charlotte
- 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.

Group Intervention Description Auditory Feedback Auditory Feedback Participants will complete 8 sessions over a 2-week period of walking gait retraining on a treadmill while receiving auditory feedback. No Feedback No Feedback Participants will complete 8 sessions over a 2-week period of walking on a treadmill without receiving feedback.
- Primary Outcome Measures
Name Time Method Changes from baseline in talar cartilage deformation before and after walking 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 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 Immediate post-intervention, 1-week post-intervention Plantar pressure and center of pressure trajectory measured with an in-shoe plantar pressure system
- Secondary Outcome Measures
Name Time Method Changes from baseline in static balance Immediate post-intervention, 1-week post-intervention Static balance will be measured via a force plate
2. Changes from baseline in plantar pressure during forward lunges, lateral hops, and a step-down Immediate post-intervention, 1-week post-intervention Plantar pressure during forward lunges, lateral hops, and a step-down will be recorded with an in-shoe insole system.
