Because of the inability of strength tests to accurately discriminate between low back pain patients and healthy subjects, a multifactorial evaluation of low back pain patients is warranted. It is postulated that measurements of endurance, kinematics, postural stability, and coordination, in addition to strength, are necessary to fully document the patients' functional capabilities. This research study was conducted in order to understand the effects of fatigue on the above factors. Twelve healthy male subjects performed a repetitive lifting test in which a submaximal load was lifted at a maximal rate. Knee, hip, and trunk motion was measured using videography and electrogoniometry, postural stability was measured using a forceplate, and coordination parameters were determined using phase-plane analysis. Fatigue was documented by a 31% reduction in lifting power. At the end of the endurance test, there was less knee and hip range of motion and greater spine peak flexion, while the coordination measures demonstrated that there was greater hip and lumbar spine extension earlier in the lifting phase. The postural stability declined as the test endured. Utilization of these measures may guide physical therapists in their rehabilitation of low back pain patients.
由于力量测试无法准确区分腰痛患者和健康受试者，因此有必要对腰痛患者进行多因素评估。据推测，除了力量之外，对耐力、运动学、姿势稳定性和协调性的测量对于全面记录患者的功能能力是必要的。进行这项研究是为了了解疲劳对上述因素的影响。12名健康男性受试者进行了一项重复性举重测试，以最大速度举起次最大负荷。使用摄像和电子测角仪测量膝盖、臀部和躯干的运动，使用测力板测量姿势稳定性，并使用相平面分析确定协调参数。通过举重力量降低31%记录疲劳情况。在耐力测试结束时，膝盖和臀部的活动范围减小，脊柱最大前屈增加，而协调测量表明，在举重阶段早期，臀部和腰椎的伸展增加。随着测试的进行，姿势稳定性下降。这些测量方法的应用可能会指导物理治疗师对腰痛患者进行康复治疗。
