Abstract

[Purpose] This study aimed to determine the influence of toe grip strength exertion in the sitting position at low seat height on toe grip strength and muscle activity in order to identify the appropriate measurement position. [Subject and Methods] The study subjects were 20 healthy women. We compared toe grip strength and muscle activity between two positions, hip and knee joints at 90°flexion position on the edge of a seat and sitting position at low seat height. The activities of the following leg muscles were recorded: rectus femoris, biceps femoris, medial head of the gastrocnemius, and tibialis anterior. We then calculated the percent integrated electromyography values during toe gripping. [Results] We found that toe grip strength was significantly lower in the sitting position at low seat height than when the hip and knee joints were at 90°flexion. Moreover,the percent integrated electromyography values of the rectus femoris and tibialis anterior in the sitting position at low seat height were significantly higher than those of the hip and knee joints at 90°flexion. [Conclusion] The results of this study suggest that the toe grip strength in the sitting position at low seat height was kept low to inhibit the increase in muscle activity.
