Abstract

Objectives: This study aimed to investigate the relationship between spinal alignment and trunk muscle strength, sitting balance and functionality in individuals with spinal cord injury.

Methods: This study included 46 individuals with spinal cord injury (SCI) at T7 or below (AIS A or B) (mean age: 38.93 ± 14.43). Spinal alignment in a sitting posture was assessed using the DIERS Formetric Functional Spine and Posture Analysis System, while trunk muscle strength was measured with the DIERS Myoline Isometric Muscle Force Analysis System. Trunk balance was evaluated using the Trunk Control Test (TCT), Function in Sitting Test (FIST), and Modified Functional Reach Test (mFRT). Functional ability and independence were assessed with the Spinal Cord Independence Measure (SCIM-III).

Results: The analysis of the relationship between spinal alignment and trunk isometric muscle strength revealed a moderate positive correlation between trunk extensor strength and trunk length (r_s = -0.502) and a moderate negative correlation with vertebral rotation (+max) (r_s = -0.555). Also, a moderate negative correlation was found between trunk flexor strength and vertebral rotation (+max) (r_s = -0.480). No correlation was found between the spinal alignment and balance and functionality.

Conclusions: This study shows that trunk extensor strength is significantly associated with spinal alignment parameters, such as vertebral rotation and trunk length, in individuals with spinal cord injury. However, no relationship was found between spinal alignment and sitting balance or functional performance. These results suggest that combining postural assessment and trunk strengthening in rehabilitation may help improve posture and mobility.

探讨脊髓损伤中脊柱直向与躯干肌力、坐位平衡及功能的关系。

目的：本研究旨在探讨脊髓损伤患者脊柱对齐与躯干肌肉力量、坐位平衡和功能之间的关系。方法：本研究纳入46例T7及以下（AIS A或B）脊髓损伤患者（平均年龄：38.93±14.43）。使用DIERS功能脊柱和姿势分析系统评估坐姿时的脊柱对齐，使用DIERS肌线等距肌力分析系统测量躯干肌肉力量。使用躯干控制测试（TCT）、坐位功能测试（FIST）和改良功能伸展测试（mFRT）评估躯干平衡。用脊髓独立性量表（sci - iii）评估功能能力和独立性。结果：脊柱直线与躯干等长肌力的关系分析显示，躯干伸肌强度与躯干长度呈中度正相关（rs = -0.502），与椎体旋转呈中度负相关（rs = -0.555）。此外，躯干屈肌强度与椎体旋转（+max）之间存在中度负相关（rs = -0.480）。脊柱排列与平衡和功能之间没有相关性。结论：本研究表明，在脊髓损伤个体中，躯干伸肌强度与脊柱对准参数（如椎体旋转和躯干长度）显著相关。然而，没有发现脊柱排列与坐姿平衡或功能表现之间的关系。这些结果表明，在康复中结合姿势评估和躯干强化可能有助于改善姿势和活动能力。
