The purpose of this study was to compare the secondary axes activity of normal subjects and low back pain patients. Each subject performed maximum isometric trials in all six primary directions. This was followed by five dynamic repetitions in each of the cardinal planes against relative resistances set at 50% of the recorded maximum isometric torques for each axis. The results showed that for all movement axes the secondary axes torques were significantly less (p = 0.01-0.001) for low back pain patients compared to normal subjects. The secondary axes torques were generally weakly related to an individual's ability to both generate maximum isometric torques about the same axis and the primary axes maximum velocities.
本研究的目的是比较正常受试者和腰痛患者的次要轴活动。每位受试者在所有六个主要方向上进行最大等长试验。随后,在每个基本平面上进行五次动态重复,对抗设置为每个轴记录的最大等长扭矩的50%的相对阻力。结果显示,与正常受试者相比,腰痛患者在所有运动轴上的次要轴扭矩均显著更小(p = 0.01 - 0.001)。次要轴扭矩通常与个体在同一轴上产生最大等长扭矩的能力以及主要轴的最大速度之间存在弱相关性。
