To determine whether proprioceptive impairments exist in patients with low back pain (LBP). We hypothesized that patients with LBP would exhibit larger trunk proprioception errors than healthy controls.
Case-control study.
University laboratory.
24 patients with nonspecific LBP and 24 age-matched healthy controls.
Not applicable.
We measured trunk proprioception in all 3 anatomical planes using motion perception threshold, active repositioning, and passive repositioning tests.
LBP patients had significantly greater motion perception threshold than controls (P<.001) (1.3+/-0.9 degrees vs 0.8+/-0.6 degrees ). Furthermore, all subjects had the largest motion perception threshold in the transverse plane (P<.001) (1.2+/-0.7 degrees vs 1.0+/-0.8 degrees for all other planes averaged). There was no significant difference between LBP and healthy control groups in the repositioning tasks. Errors in the active repositioning test were significantly smaller than in the passive repositioning test (P=.032) (1.9+/-1.2 degrees vs 2.3+/-1.4 degrees ).
These findings suggest that impairments in proprioception may be detected in patients with LBP when assessed with a motion perception threshold measure.
确定是否存在腰痛（LBP）患者的本体感觉障碍。我们假设 LBP 患者的躯干本体感觉误差会大于健康对照组。
病例对照研究。
大学实验室。
24 名非特异性 LBP 患者和 24 名年龄匹配的健康对照者。
不适用。
我们使用运动知觉阈、主动重定位和被动重定位测试测量了所有 3 个解剖平面的躯干本体感觉。
LBP 患者的运动知觉阈值明显高于对照组（P<.001）（1.3+/-0.9 度比 0.8+/-0.6 度）。此外，所有受试者在横切面上的运动知觉阈值最大（P<.001）（1.2+/-0.7 度比所有其他平面的平均值 1.0+/-0.8 度）。在重定位任务中，LBP 组与健康对照组之间无显著差异。主动重定位测试中的误差明显小于被动重定位测试（P=.032）（1.9+/-1.2 度比 2.3+/-1.4 度）。
这些发现表明，当使用运动知觉阈值测量时，可能会在 LBP 患者中检测到本体感觉障碍。
