The purpose of this study was to examine the effects of Biodex stability training on the onset of muscle activity and balance measures in participants with functional ankle instability (FAI). The musculature onset and peak latency of the peroneals, tibialis anterior and soleus of 15 patients with FAI were recorded with surface electromyography (EMG) in response to sudden 10°, 20° and 30° inversions by an Ankle Perturbation System (APS), both before and after stability training. Participants underwent a monitored 4-week Biodex stability program (12 min per session, three times a week). Pre-and post-training balance measures were also recorded by the Biodex Stability System. The results showed that post-training, there was a significant decrease in muscle onset and peak latency for the peroneals and tibialis anterior, and a significant improvement in balance measures. The authors conclude that based on the present results, a Biodex stability exercise program may be recommended for the rehabilitation of FAI.
