Effects of Real-Time Video Feedback on Plantar Pressure Measures In Individuals With Chronic Ankle Instability During Walking.

Individuals with chronic ankle instability (CAI) have been shown to have increased lateral plantar pressure during walking which is thought to contribute to symptoms associated with CAI. The objective of this study was to determine whether real-time video feedback can reduce lateral plantar pressure in individuals with CAI. Twenty-six participants with CAI completed 30 s of treadmill walking while plantar pressure was measured using an in-shoe plantar pressure system (baseline). Next, participants completed an additional 30 s of treadmill walking while receiving video feedback (VID FB). During the VID FB condition, participants had a significant decrease in medial forefoot peak pressure and medial midfoot pressure-time integral; however, both changes were associated with small effect sizes. Real-time video feedback did not reduce lateral plantar pressure in individuals with CAI; therefore, other gait retraining strategies should be considered when treating patients with CAI.
