The purpose of this study was to compare the preferred low-back motion of normal subjects and low-back-pain patients. Each subject performed a maximum isometric flexion trial followed by repeated flexion and extension against a relative resistance set at 50% of the recorded maximum flexion isometric torque. The subjects were instructed to move at their own pace through their preferred movement range until either exhaustion or for 120s. The results showed that the groups differed significantly in their preferred motion characteristics, although the performances were equally consistent.
本研究的目的是比较正常受试者和腰痛患者腰部的偏好运动。每位受试者先进行一次最大等长屈曲试验,然后以记录的最大屈曲等长扭矩的50%为相对阻力进行反复屈伸运动。受试者被要求按照自己的节奏在偏好的运动范围内移动,直至力竭或持续120秒。结果显示,尽管两组的表现同样稳定,但他们的偏好运动特征存在显著差异。
