Abstract

健常な成人18名 (男性13名, 女性5名) を対象にし, 片脚立位で足部を内反強制, 外反強制させた際の下肢アライメントの変化と下肢筋活動の動態について調査した。その結果, 下肢アライメントの変化は前額面上膝関節・足関節部での変化はなく, 脛骨傾斜角の変化と共に距骨下関節での変化が大きかった。また外反強制で下肢アライメントの変化が大きかった。下肢筋活動の動態は非強制と内反強制の筋活動に比して, 外反強制の筋活動は増加していた。以上の結果から, 足部を外反強制した際, 下肢支持脚としてバランスをとるのが困難な状態にある事を示唆した。

The purpose of this study was to examine changes in alignment of the lower limbs and the movement of muscle activity of the lower limbs making the foot invert and evert during standing on one leg. Eighteen healthy adults were studied in the change in alignment reontgenographycally and 5 out of 18 were studied in the movement of muscle activity electromyographically. They showed no changes in femoro-tibial angle and talo-tibial angle, but notable change in subtalar joint including tibial tilting angle by frontal plane of X ray films. Eversion, compared with inversion, changes in alignment were more intensive, increasing the volume of muscle activity. These results suggested that the compulsive eversion would be difficult to stabilize the supporting legs.
