To compare multidirectional seated postural stability between individuals with spinal cord injury and able-bodied- individuals and to evaluate the impact of abdominal and low back muscle paralysis on multidirectional seated stability.
Case-control study.
Fifteen individuals with complete or incomplete spinal cord injury affecting various vertebral levels participated in this study and were gender-matched with 15 able-bodied individuals.
Participants were instructed to lean as far as possible in 8 directions, set apart by 45° intervals, while seated on an instrumented chair with their feet placed on force plates. Eight direction-specific stability indices and a global stability index were calculated.
The global stability index and all direction-specific indices, except in the anterior and posterior directions, were lower in individuals with spinal cord injury than in able-bodied individuals. However, the individuals with spinal cord injury who had partial or full control of their abdominal and lower trunk muscles obtained a similar global stability index and similar direction-specific indices compared to the able-bodied individuals.
Multidirectional seated postural stability is reduced in individuals with SCI who have paralysis of the abdominal and lower back muscles in comparison to able-bodied individuals.
比较脊髓损伤患者与健全个体的多向坐姿平衡，并评估腹部和下背部肌肉瘫痪对多向坐姿稳定性的影响。
病例对照研究。
15 名不同节段完全或不完全脊髓损伤的个体参与了这项研究，他们与 15 名健全个体进行了性别匹配。
参与者被要求坐在带测力板的仪器椅上，双脚着地，尽可能向 8 个方向倾斜，间隔 45°。计算了 8 个方向特异性稳定性指数和一个整体稳定性指数。
与健全个体相比，脊髓损伤患者的整体稳定性指数和所有方向特异性指数（前、后方向除外）均较低。然而，部分或完全控制腹部和下躯干肌肉的脊髓损伤患者获得了与健全个体相似的整体稳定性指数和相似的方向特异性指数。
与健全个体相比，下背部肌肉瘫痪的脊髓损伤患者的多向坐姿平衡能力降低。
