Shoulder proprioception was measured in 90 subjects who were assigned to three experimental groups: group 1 (n = 40), healthy college-age subjects; group 2 (n = 30), patients with anterior instability; and group 3 (n = 20), patients who have had surgical reconstruction. Kinesthesia and joint position sense were measured with a specially designed proprioception testing device. The results revealed no significant differences in proprioception between dominant and nondominont shoulders in group 1 for any test condition. Significant differences (p < 0.05) were revealed between the unstable and uninvolved shoulder for both kinesthesia and joint position sense in group 2. No significant mean differences were revealed between the surgical and contralaterol shoulder in group 3 under any test condition. This series of studies provides evidence that proprioceptive deficits caused by partial deafferentiation result when copsuloligomentous structures are damaged. Reconstructive surgery appears to restore some of these proprioception characteristics.
对90名受试者的肩部本体感觉进行了测量，这些受试者被分为三个实验组：第1组（n = 40），健康的大学年龄受试者；第2组（n = 30），前交叉不稳定患者；第3组（n = 20），接受过手术重建的患者。使用专门设计的本体感觉测试设备测量运动觉和关节位置觉。结果显示，在任何测试条件下，第1组中优势肩和非优势肩之间的本体感觉无显著差异。第2组中，不稳定肩和未受累肩在运动觉和关节位置觉方面均存在显著差异（p < 0.05）。在任何测试条件下，第3组中手术侧肩部和对侧肩部之间均未显示出显著的平均差异。这一系列研究提供了证据，表明当关节囊韧带结构受损时，会因部分传入神经阻滞导致本体感觉缺陷。重建手术似乎能恢复其中一些本体感觉特征。
