Proprioception testing and gait analysis was performed on a group of 17 patients with idiopathic scoliosis. All curves had documented progression. The average curve was 26.8 degrees, all primary curves being right thoracic. The average age was 14.8 years. Twelve, healthy, age-matched controls underwent identical testing. Results showed that scoliotic subjects had asymmetry in their ability to reproduce angles between their two knees, as well as an absolute deficit in their ability to reproduce angles as compared with controls (P less than 0.01). The threshold of detection of change in angle at the knee was also quantitatively higher than controls (P less than 0.05), although asymmetry was not statistically significant. No significant differences were measured in gait parameters between scoliotics and controls. These joint position tests have been applied previously to young and elderly adults, athletes, and total joint patients. In no group has any asymmetry of response been demonstrated, both extremities showing virtually identical performance in each case. The tests administered measure sensory modalities, which are conducted through the posterior columns. Although the site of damage in the neural pathway cannot be specifically localized by these tests, results of this study support the presence of a neurologic deficit in idiopathic scoliosis.
对一组17例特发性脊柱侧凸患者进行了本体感觉测试和步态分析。所有侧弯均有进展记录。平均侧弯角度为26.8度，所有主弯均为右胸弯。平均年龄为14.8岁。12名年龄匹配的健康对照者接受了相同的测试。结果显示，脊柱侧凸患者在重现双膝间角度的能力上存在不对称，与对照组相比，其重现角度的能力也绝对不足（P<0.01）。膝关节角度变化的检测阈值在数量上也高于对照组（P<0.05），尽管不对称性无统计学意义。脊柱侧凸患者与对照组在步态参数方面未测得显著差异。这些关节位置测试先前已应用于年轻人和老年人、运动员以及全关节置换患者。在任何组中均未显示出反应的不对称性，在每种情况下，双侧肢体的表现几乎相同。所进行的测试测量通过后柱传导的感觉模式。尽管这些测试不能特异性定位神经通路中的损伤部位，但本研究结果支持特发性脊柱侧凸存在神经功能缺损。
