Injury prevention

Document Type



Ankle braces are often worn to prevent ankle injuries. Evidence supports their ability to prevent ankle injuries; however, the effects that ankle braces have on proximal biomechanics and injuries is unclear. This pilot study explored the effects of ankle braces on lower extremity electromyographic (EMG) activity and vertical ground reaction force (vGRF) during a jump landing. Ten healthy individuals completed 3 maximum vertical jumps under 3 bilateral conditions (no braces, softshell (AE) braces, and semi-rigid (T1) braces). Mean EMG activity and peak vGRF was recorded from the dominant leg at landing. No significant differences in lower extremity EMG activity or peak vGRF was present when wearing ankle braces. Trends exist in the data that warrant further investigation in a larger sample.
