Twenty-three patients with idiopathic scoliosis were tested for upper extremity proprioceptive function. All subjects had documented progression of deformity, with an average curvature of 34 degrees. The average ages for scoliotics and 18 control subjects were 16.1 and 20.8 years, respectively. Controls had no spinal deformity and underwent identical test procedures. The test results showed that scoliotic subjects had significant asymmetry between right and left limbs in their threshold for detection of joint motion (p less than or equal to 0.005) and in their ability to reproduce angles to which their elbow joint had been previously positioned (p less than or equal to 0.025). Slight asymmetry also was observed in the reproduction tests of the control group (p less than or equal to 0.013); however, there was no significant asymmetry seen in this group for the threshold test. Performance of bilateral limbs was designated good and bad for both groups; the limb that performed better in proprioceptive function was designated good limb. Analysis of data showed that the scoliotics' good and bad limbs performed inferiorly in both threshold and angle reproduction tests when compared with normal controls. The results of this study imply, but do not localize, a neurologic deficit in scoliotic patients.
对23例特发性脊柱侧凸患者进行了上肢本体感觉功能测试。所有受试者均有畸形进展记录，平均曲率为34度。脊柱侧凸患者和18名对照受试者的平均年龄分别为16.1岁和20.8岁。对照组无脊柱畸形，且接受相同的测试程序。测试结果表明，脊柱侧凸受试者在检测关节运动的阈值（p≤0.005）以及再现其肘关节先前所处角度的能力（p≤0.025）方面，左右肢体存在显著不对称。在对照组的再现测试中也观察到了轻微不对称（p≤0.013）；然而，该组在阈值测试中未观察到显著不对称。将两组双侧肢体的表现分为良好和不良；本体感觉功能表现较好的肢体被指定为良好肢体。数据分析表明，与正常对照组相比，脊柱侧凸患者的良好和不良肢体在阈值和角度再现测试中的表现均较差。本研究结果暗示但未定位脊柱侧凸患者存在神经功能缺损。
