A prototype sagittal plane trunk strength tester was used to measure trunk strength in 286 chronic low-back pain patients. Initial data for this patient group are compared with data acquired previously from a group of controls, adjusted for age, sex, and body weight. Distinct patterns characterize the patient sample as opposed to the controls: Patient values for both flexors and extensors were markedly decreased, with greater variability; Extensor strength was affected more significantly than flexor strength; Discrepancies between patients and controls were greater for females than for males; High-speed dropoff ratios were much lower for patients, both in flexion and extension. These results demonstrate that strength deficits are a major factor in the deconditioning syndrome associated with chronic low-back pain.
使用一种矢状面躯干力量测试仪对286名慢性下背痛患者的躯干力量进行测量。将该患者组的初始数据与先前从一组对照组获取的数据进行比较，并根据年龄、性别和体重进行了调整。与对照组相比，患者样本呈现出不同的模式：屈肌和伸肌的患者数值均显著降低，且变异性更大；伸肌力量比屈肌力量受到的影响更显著；女性患者与对照组之间的差异比男性更大；患者在屈伸时的高速下降率要低得多。这些结果表明，力量不足是与慢性下背痛相关的失健综合征的一个主要因素。
