[Purpose] This study investigated how the toe spreader affects muscle activities during gait in order to enhance the clinical decision-making process regarding the different characteristics of toe spreader materials. [Subjects] Twenty healthy participants were recruited. [Methods] Repeated measures of tibialis anterior (TA) and peroneus longus (PL) EMG activities (%RVC) were evaluated with and without toe separators made of two different materials (i.e., soft and hard). [Results] Compared to walking without a toe spreader, TA activity was significantly increased by the soft toe spreader and was decreased by the hard one. PL activity was significantly decreased by the soft toe spreader. [Conclusion] The altered TA and PL activities observed in this study may be the result of the toe spreader providing medio-lateral foot support during walking.

[Purpose] The aim of this study was to investigate the EMG amplitude of the gluteus maximus (GMax) and medius (GMed) during 6 exercises with and without a pelvic belt. [Subjects] Twenty healthy males were recruited. [Methods] The belt was positioned below the anterior superior iliac spine. Surface EMG was used to measure the GMax and GMed activity of the dominant limb during exercise. The percentage of the EMG amplitude relative to maximal voluntary isometric contraction was analyzed with a mixed within-between subjects analysis of variance (ANOVA). [Results] This study showed significantly increased GMax activity in the pelvic belt condition as a main effect. However, there was no significant effect on GMed activity except with the hip clam. [Conclusion] The pelvic belt significantly improved GMax activity during exercises in contrast to the GMed activity. When treating people with weakness of gluteal muscles, the functional specific exercises with a pelvic belt have the beneficial effect of associated muscle strengthening.
