Abstract: 今回,Heel Gait Cast療法の痙性緩解の作用であると思われる足関節背屈位保持,及び踵部圧,皮膚刺激について,それらが同側下腿三頭筋支配の脊髄運動細胞の興奮性にどのような影響を及ぼすかについてH波振幅比較法を用い検討した.その結果,コントロール時と比較し,①足関節中間位での足関節に圧縮刺激を加えたとき増加傾向にあったが有意差は認められなかった.②足関節10度背屈位では有意な減少を示した.③足関節10度背屈位で圧縮刺激を加えた場合,有意差は認められなかった.以上から,Heel Gait Cast療法の痙性緩解は足関節を背屈位に保持し,持続的に足関節底屈筋群に伸張を加えることによるものと推察された. / As to the mechanism of the Heel Gait Cast method to relieve the spasticity, the following two points were investgated by means of H wave. (1) Whether continuously slow stretching upon the extensors of the ankle joint will inhibit the α-motor neuron activity of the m. triceps surae. (2) Axial compression of the ankle joint how to excite the α-motor neuron of the m. triceps surae. In comparion to control, ① through compression, H wave increased but it was not statistically significant, ② through 10 degrees dorsiflexion, H wave decreased signifficantly, ③ through 10 degrees dorsiflexion and compression, H wave decreased but not signifficant. It was concluded that the spasticity may be relieved by the continuous stretching of the m. triceps surae.
