摘要

本實驗之目的在測量正常人腰部伸肌和屈肌力量之數值，利用33名在本部實習並沒有背痛病史的同學。
男17名，女16名．平均年齡24.3歲，平均體重58.8KG，平均身高165.6CM經過5分鐘的暖身活動後，採半坐姿以L5為軸心，用KINETIC COMMUNICATOR KIN-COM Ⅲ機器以等長收縮模式，來測量軀幹屈肌和伸肌的力量(TORQUE Newton-Meter)以病人較能接受，並可去除重力影響的軀幹直立姿勢得到屈肌和伸肌的TORQUE值。
此實驗發現軀幹之屈肌和伸肌其TORQUE位分別和身高，體重成正比，但屈肌和伸肌之比值並不受身高，體重和性別之影響，它幾乎有一固定之比值約2.05l SD0.315因此可得一結論：採用KIN-COM Ⅲ之等長收縮模式測量身體軀幹之力量有良好之耐受性，並且希望所得伸肌和屈肌的比值，可做為將來下背痛病患腰部肌肉川練之依據。

The purpose of this study was to use the KINEMETIC COMMUNICATOR KIN-COM III (a computer controlled dynamometer) in the isometric mode to estabilish flexion and extension guidelines for a trunk rehabilitation exercise program.
Trunk activity was assessed in 33 young normal adults without LBP history.
L5 was taken as the trunk flexion / extension center and the semi-sitting erect position was used to eliminate the gravity effect.
We found that the trunk flexion and extension torques were positively related to the height and weight. The Extenision: Flexion ratio was approximately 2:l(mean 2.051 + 0.315). This data may be use as a guideline for trunk rehabilitation exercise progrom.
Since none of the 33 students tested complained of any immediate low back pain or other cardio-pulmonary problems, except for some slight anterior chest wall soreness reported by few. we can also affirm that it is safe to use the isometric mode for testing trunk activity.
