Effects of biomechanical ankle platform system on electromyographic activity of the anterior tribialis and the peroneus longus

1 May 1990


The change in muscle EMG activity following a treatment on the Biomechanical Ankle Platform System (BAPS) was the focus of this study. Sixty subjects were randomly assigned to one of four groups. The first group received a two minute SAPS treatment and activity of the anterior tibialis (AT) was recorded. The second group was a control group for the AT. Another group received a two minute BAPS treatment and activity of the peroneus longus (PL) was recorded. The last group was the control group for the PL. The subjects, 22 males and 38 females, ranged in age from 18 to 75 years old, and had no severe ankle injuries requiring medical attention in the past two years. Baseline readings of the electromyographic (EMG) activity of the assigned muscle were taken and compared with final EMG readings following two minutes of normal stance or the BAPS treatment. The difference in scores was analyzed using independent two-tailed t-tests to compare the two groups associated with each muscle studied; the results were found to be statistically insignificant.
