Acute Effects of Biomechanical Muscle Stimulation to Lower Extremity Using the Swisswing® on SEBT Scores in Persons With and Without Chronic Ankle Instability

The objective of this study was to investigate the acute effects of biomechanical muscle stimulation (BMS) on neurological control by evaluating performance on the star excursion balance test (SEBT) among uninjured and chronic ankle instability (CAI) subjects. Forty subjects aged 18 to 26 who participated in physical activity at least two times a week were placed in two groups: CAI or non-CAI group. Subjects performed 4 unscored SEBT practice attempts before completing 3 baseline tests were recorded and averaged. Experimental groups (CAI and Non-CAI) performed a 3 seated BMS intervention for 2 minutes each at 20 Hz: bottom of foot with both feet; heels of both feet; and gastrocnemius belly of both legs. Control group (CAI and Non-CAI) received no intervention and simply sat for 9 minutes. Three posttest SEBTs were recorded and averaged. A delta score was calculated by finding a change score between pre and post for each of the 8 directions of the SEBT. The MANOVA for SEBT change scores revealed no statistically significant differences between CAI and Non-CAI in both experimental and control groups relative to excursion direction (p > 0.05). Further analysis revealed a main effect of group (experimental and control) showing statistical significance (F = 6.317, p = 0.017) when using change scores in all excursion directions. Results suggest that the BMS intervention can have a positive effect on SEBT performance in a variety of populations.
