The purpose of this study is to examine the effect of the range of motion (ROM) in pronation of the transverse tarsal joint on trunk motion in standing and hemi-standing. We investigated whether ROM on pronation of the transverse tarsal joint affected trunk rotation in standing and hemi-standing. Subjects were eight healthy persons (five males and three females), sixteen lower extremities. Each subject had bilateral ROM on pronation of the transverse tarsal joint measured with a goniometer, and classified sa the hypo-mobility side (ROM on pronation of transverse tarsal joint <10°) or normal-mobility side (ROM on pronation of the transverse tarsal joint ≥10°). And each subject also had ROM of trunk rotation measured on the supporting side in standing and hemi-standing with a goniometer. We compared the normal-mobility side with the hypo-mobility side as to the ROM of trunk rotation in standing and hemi-standing. Compared with the normal-mobility side, the ROM of trunk rotation was significantly decreased on the hypo-mobility side in hemi-standing (p<0.01). Consequently, the limitation of ROM in pronation of the transverse tarsal joint increases the degree of eversion of the subtalar joint in hemi-standing, and increases the degree of eversion of the subtalar joint in hemi-standing causing loss of stability of the lower extremities in hemi-standing. As a result of this study, we believe that on the hypo-mobility side, loss of stability of the lower extremities disturbs the cooperative connection between the lower extremities and the pelvis in hemi-standing. We concluded that trunk rotation in hemi-standing on the hypo-mobility side is decreased due to disturbance of the cooperative connection between the lower extremities and the pelvis in hemi-standing.
