Background: Shoulder impingement syndrome (SIS) is the second most common musculoskeletal condition that causes shoulder pain in the general population. Shoulder girdle muscle imbalance and posterior capsule tightness have been implicated as contributing factors. Objective: The purpose of this study was to investigate the effect of shoulder stability exercises (SSEs) on hand grip strength in patients with unilateral SIS. Methods: A total of 16 patients with a mean age of 32 ± 9.3 years diagnosed with stage II unilateral SIS participated in this study. A standardized SSE programme was conducted in the clinic under the direct 1-to-1 supervision of a physical therapist thrice weekly for 4 weeks for a total of 12 sessions on the affected and non-affected shoulders. The effect of the SSE programme on isometric hand grip strength was analysed. Results: A significant difference (p = .016) was observed in the hand grip strength of the affected shoulder side before and after the intervention, but no significant difference (p = 1.0) was found in the hand grip strength of the non-affected shoulder side post-intervention. Conclusion: The reduction in isometric hand grip strength of the affected shoulder side compared to that of the non-affected shoulder side in the same subject before the intervention shows that SIS significantly affects the hand grip strength of the affected side. SSEs significantly affect the isometric hand grip strength of SIS patients.

肩部稳定锻炼对肩部撞击综合征患者手部握力的影响。

背景：肩部撞击综合征（SIS）是第二种最常见的肌肉骨骼疾病，在一般人群中会引起肩部疼痛。肩带肌肉失衡和后囊紧实已被认为是促成因素。目的：本研究的目的是研究单侧SIS患者肩部稳定锻炼（SSE）对握力的影响。方法：共有16例平均年龄32±9.3岁的被诊断为II期单侧SIS的患者参加了这项研究。诊所在物理治疗师的直接一对一监督下，每周三次三次，在受影响的和未受影响的肩膀上进行标准的SSE计划，每周三次，为期4周。分析了SSE程序对等距握力的影响。结果：在干预前后，患侧肩侧的握力有显着差异（p = .016），但未患侧肩侧的握力没有显着差异（p = 1.0）干预后。结论：在干预之前，同一受试者的患侧肩部等距握力与未患侧肩部相比降低，这表明SIS显着影响了患侧的握力。SSE会严重影响SIS患者的等距握力。干预后未受影响的肩侧的手握强度发现为0）。结论：在干预之前，同一受试者的患侧肩部等距握力与未患侧肩部相比降低，这表明SIS显着影响了患侧的握力。SSE会严重影响SIS患者的等距握力。0）被发现干预后未受影响的肩侧的握力。结论：在干预之前，同一受试者的患侧肩部等距握力与未患侧肩部相比降低，这表明SIS显着影响了患侧的握力。SSE会严重影响SIS患者的等距握力。
