Shoulder Elbow. 2025 Apr 4:17585732251328338. doi: 10.1177/17585732251328338.
The proximal-distal energy transfer between body segments occurs through the kinetic chain. Although some kinetic chain aspects have been investigated in individuals not engaged in sports, their relationship with shoulder pain in this population remains unclear. This cross-sectional study aimed to verify associations between kinetic chain factors and the presence of shoulder pain in adults.
Lumbopelvic stability (single-leg bridge test); active range of motion of the shoulder, trunk, and hip; and isometric peak strength of shoulder, trunk, hip, and knee muscles were assessed. A multivariate binary logistic regression analyzed the likelihood of shoulder pain based on these clinical results.
Forty individuals (26.3 ± 10.4 years, 19 with shoulder pain) were assessed. The isometric strength of trunk extensor muscles significantly influenced the regression model (odds ratio = 0.99 [0.98-1.00]; = 0.027), indicating that each 1 N increase in strength reduced the likelihood of shoulder pain by about 1%. No significant relationships were observed between other outcomes and shoulder pain.
Isometric strength of trunk extensor muscles may be associated with shoulder pain. No associations were observed between shoulder pain and stability, mobility, and strength of other kinetic chain segments.
身体各节段之间的近端到远端能量传递通过动力链发生。虽然一些动力链方面的情况已在非运动人群中进行了研究，但它们与该人群肩部疼痛的关系仍不明确。这项横断面研究旨在验证动力链因素与成年人肩部疼痛存在之间的关联。
评估腰骨盆稳定性（单腿桥测试）；肩部、躯干和髋部的主动活动范围；以及肩部、躯干、髋部和膝部肌肉的等长峰值力量。多变量二元逻辑回归基于这些临床结果分析肩部疼痛的可能性。
对40名个体（26.3±10.4岁，19名有肩部疼痛）进行了评估。躯干伸肌的等长力量对回归模型有显著影响（比值比 = 0.99 [0.98 - 1.00]；P = 0.027），表明力量每增加1 N，肩部疼痛的可能性降低约1%。未观察到其他结果与肩部疼痛之间存在显著关系。
躯干伸肌的等长力量可能与肩部疼痛有关。未观察到肩部疼痛与其他动力链节段的稳定性、活动度和力量之间存在关联。
