[Purpose] This study examined the effects of different weight-bearing postures on the activation of the abductor hallucis muscle during foot-arch exercises. [Subjects] The study recruited 11 healthy volunteers who were pain-free, had no history of foot or ankle surgery, and were able to maintain a standing posture. [Methods] The subjects performed short-foot and toe-spreading exercises while sitting and standing. [Results] The abductor hallucis muscle activation in the toe-spreading exercise was significantly greater when standing than in sitting, while that in the short-foot exercise did not differ significantly between the two postures. [Conclusion] The results of this study suggests that a weight bearing posture such as standing is the most effective method of increasing the EMG activity of abductor hallucis muscle in the toe-spreading exercise.
