Neuromuscular control is important for joint stabilization. Supraspinatus muscle plays an essential role in the perception of proprioceptive sense. The aim of this study is to investigate active joint position sense (AJPS) both in patients with partial and full-thickness supraspinatus tears and in healthy participants.
Twenty patients with partial supraspinatus tears, 20 patients with full-thickness supraspinatus tears, and 20 healthy participants, aged 40-65 years, were included in the study. Proprioceptive sense was assessed with AJPS measurement. Absolute error was calculated to evaluate joint position sense.
Active joint position sense was decreased in partial and full-thickness tears on both in affected and contralateral shoulders compared to control group (p < 0.05). There was no difference between groups with partial and full-thickness tears on the affected and contralateral shoulders at 40° and 100° elevation (p > 0.05).
AJPS was affected after supraspinatus injury. It was seen as proprioceptive deficit in patients with partial and full-thickness tears in both affected and contralateral shoulders.
神经肌肉控制对关节稳定很重要。冈上肌在本体感觉的感知中起重要作用。本研究的目的是调查部分和全层冈上肌撕裂患者以及健康参与者的主动关节位置觉（AJPS）。
本研究纳入了20例部分冈上肌撕裂患者、20例全层冈上肌撕裂患者和20名年龄在40 - 65岁的健康参与者。通过AJPS测量评估本体感觉。计算绝对误差以评估关节位置觉。
与对照组相比，部分和全层撕裂患者患侧和对侧肩部的主动关节位置觉均降低（p < 0.05）。在40°和100°抬高时，部分和全层撕裂组患侧和对侧肩部之间无差异（p > 0.05）。
冈上肌损伤后AJPS受到影响。在部分和全层撕裂患者的患侧和对侧肩部均表现为本体感觉缺陷。
