Optimizing Retention on Duty in Patients With Chronic Ankle Instability Using Auditory Biofeedback Gait Training: A Multisite Randomized Controlled Trial
University of Kentucky
Summary
The goal of this randomized clinical controlled trial is examine the effects of gait training with auditory biofeedback (AudFB) on gait biomechanics, clinical measures of ankle joint health, and patient-centered outcomes. The following specific aims will achieve this objective: * Specific Aim 1: Determine if a 6-week gait training with AudFB intervention improves lower extremity biomechanics compared to a Control condition in participants with CAI. * Specific Aim 2: Determine if a 6-week gait training with AudFB reduces talar cartilage deformation compared to a Control condition in participants with CAI. * Specific Aim 3: Determine if a 6-week gait training with AudFB reduces episodes of ankle giving-way and reduces self-perceived severity of symptoms relative to a Control condition in participants with CAI. Participants will: * Complete 12 intervention sessions over a 6-week period of walking, ruck marching, and runninig. * Complete testing sessions before and after the intervention, then after 6 and 12-months following the intervention.
Description
Background: Ankle injuries account for the highest musculoskeletal injuries among conventional and special warfare combatants. In the civilian population, 40% of lateral ankle sprain patients will develop chronic ankle instability (CAI). If the same frequency is true in military settings, then up to 36,800 service members develop CAI annually. CAI contributes to the total number of medically non-available service members, creates a substantial economic burden, impacts the quality of duty-relevant task performance, and generates a large population of service members who require long-term care a…
