The Study of Relationship between Toe and Dynamic Postural Control.

Abstract

The purposes of this study were to examine the roles of toe in dynamic postural control during horizontal and vertical movements, and to elucidate the relationship between dynamic postural control and toe grasp power in healthy young subjects. Three kinds of non-weight bearing insoles, that without weight on a great toe, that without weight on the second to fifth toes, and that without weight on all toes, and an insole of weight bearing were prepared. Center of foot pressure was measured during forward functional reach, and body sway was measured during crouching and standing motions as an index of dynamic postural control during vertical movement. Both in horizontal and vertical movements, a great toe exerted the function of supporting the shifted center of gravity, and the second to fifth toes had the function of re-centering the shifted center of gravity. These suggest a possible role of a great toe and the second to fifth toes in dynamic postural control during horizontal and vertical movements. Toe grasp power of a great toe and the second to fifth toes were measured separately by the hand-held dynamometer improved for toes. Analysis of the relationship between dynamic postural control and toe grasp power suggests that toe grasp power may reduce the body sway area. It is also suggested that toe grasp power may have an effect on dynamic postural control during vertical movement, and that strengthening of the toe grasp power may potentially decrease the risk of falling.

Occurrence of Floating Toe from the Viewpoint of the Structure of Foot Arch

“…In cases of floating toe, the force maintaining toe pressure weakens. This does not influence the static balance greatly, but it does influence the dynamic balance significantly, and it is also related to the length of stride and walking speed [2][3][4][5] .…”

Effects of Reach Balance Exercise on Toe Grip Strength and Balance in College Basketball Players

“…Copyright © 2018 The Japanese Association of Rehabilitation Medicine al., [10][11][12][13][14] there is significant correlation between the reaching distance of the arm and the toe grip strength in forward reaching movements. Schlenstedt et al 15) reported that the distance of the COP shift in the front-back direction decreased significantly after single-leg balance exercise.…”

“…Correlation has been observed between the forward reaching distance of the arm and the toe grip strength. [10][11][12][13][14] In RB-T, which requires posture control on a single leg to avoid falling, it is necessary to reach out the arm and the leg while always controlling the COP position within the base of support of the foot. It is considered that repeatedly performing this motion is effective for improving the neurogenic muscle strength of toe flexors.…”

Laterality of toe grip strength in Kendo players

“…Soma et al 5 ) indicated the relationship between TGS increase and the Functional Reach Test; maximum step length; and improvement in walking ability. In recent years, there have been several studies on TGS 6 , 7 , 8 , 9 , 10 ) . However, most of these were conducted involving healthy adults and the elderly, and there have been few reports of TGS in athletes.…”
