Effects of Gait Retraining With Auditory Feedback

Early Phase 1CompletedNCT04302961

University of North Carolina, Charlotte28 enrolled

Overview

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.

Interventions

Participants will complete 8 sessions over a 2-week period of walking gait retraining on a treadmill while receiving no feedback. Participants will be instructed to walk on a treadmill at their desired pace in a manner that does not cause the auditory tool to elicit a noise.

No FeedbackOTHER

Participants will complete 8 sessions over a 2-week period of walking gait retraining on a treadmill while receiving no feedback. Participants will be instructed to walk on a treadmill at their desired pace in a manner that they perceive to be their normal walking speed and mechanics.
