摘要：種々の垂直面内において負荷方向を変化させながら下肢の挙上を行なわせ股関節の運動に関与する下肢11筋の筋電図を記録し, 各筋の働きかたについて解剖学的, 力学的に検討した. 中殿筋前部は, 矢状面における屈曲開始位置では動作の規制のために働き, 他はいずれの面でも挙上に参画している. 中殿筋後部は, 60゜〜150゜で挙上に参画した. 大腿直筋, 縫工筋は0゜〜90゜の面で挙上に参画する. 30゜以降90゜の面ではむしろ内転の分力が生じるため, やや外向きの負荷に抗しながら動作を行った場合に放電は最も顕著であった. 長内転筋は0゜〜60゜の面では挙上に参画していた. 大腿筋膜張筋は120゜までの面では挙上に参画していた. 薄筋はいずれの面においても挙上に参画しなかった. 半膜様筋は105゜, 大腿二頭筋は150゜より挙上に参画し, 放電量はやや外向きの負荷に抗しながら行った時に顕著であった. 大内転筋は135゜以降の面で挙上(伸展)に参画した.
其他摘要：Electromyograms were recorded during elevation of the lower extremity in the various vertical planes, from 11 muscles participating in the movements. The recordings obtained were examined in terms of the functional mechanism of the muscles. The results obtained are summarized as follows: 1) The anterior portion of the gluteus medius acts as an elevator at any vertical planes except only initial part of the movement in the sagittal plane. 2) The posterior portion of the gluteus medius acts as an elevator in the vertical planes between 60 degree and 150 degree lateral from the sagittal plane. When the movement was performed against the disturbing force including a slight lateralward horizontal component, the discharge was observed in the vertical plane from 0 degree up to 180 degree. Conversely, when the movement was performed against the medialward disturbing force, the discharge was observed from 90 degree up to 135 degree lateral from the sagittal plane. 3) The sartorius and the rectus femoris act as elevators between the sagittal plane and the frontal plane. Since they have a component of adduction as they were elevated in the vertical planes between 30 and 90 degree lateral from the sagittal plane, the increase in the discharge was observed when the movement performed against the lateralward disturbing force rather than that against medialward. 4) The adductor longus participates for elevation of the thigh in the vertical planes between the sagittal and 60 degree lateral vertical plane. 5) The tensor fasciae latae actively participates for elevation of the thigh in any vertical plane up to 120 degree lateral vertical plane. 6) The discharges of the gracilis were not observed in any vertical plane. 7) The semimembranosus and the biceps femoris participate for the thigh elevation in any vertical plane beyond 105 degree and 150 degree lateral from the sagittal plane respectively. Since the muscles have a component of adduction in the movement, the increase of the discharge was observed when the movement was performed against the lateralward disturbing force. 8) The adductor magnus acts as an elevator in any vertical plane beyond 135 degree lateral vertical plane.
