目的：研究座椅配置对脊髓损伤(SCI)患者坐姿平衡的影响。设计：横断面分组研究。地点：康复中心和医院康复科。患者：10例完全上胸脊髓损伤(T2-T8级)患者，10例完全下胸脊髓损伤(T9-T12)患者，10例匹配的健康人对照。SCI参与者在研究前至少6个月已经完成了积极的康复。干预：坐在四张不同配置的椅子上时，完成了一项改变平衡(向前)的任务。倾斜角度(7度和12度)和倾斜角度(22度)相对于标准椅子配置(倾斜10度)有所变化。主要观察指标：最大无支撑到达距离、压力中心位移和肌肉活动度。结果：尽管对照组和低脊髓损伤组的主动可控伸展能力没有显著差异，但所有椅子的坐姿平衡都比标准椅子有所改善。提高了伸展过程中控制手臂和躯干移位的能力。没有发现明显需要额外的体位肌肉活动。SCI高的人没有改善他们的坐姿平衡。他们无法控制比手臂运动引起的身体质量更大的移动。然而，在靠背倾斜或椅子向后倾斜后，他们的肌肉活动较少。结论：受试椅总体上具有积极的效果。然而，对于单独定制的椅子配置，应考虑调查因素以外的因素。
Objective: To study whether chair configuration influences sitting balance in persons with spinal cord injury (SCI).Design: Cross-sectional group study.Setting: Rehabilitation centers and hospital rehabilitation departments.Patients: Ten complete high thoracic SCI (level T2-T8) patients, 10 complete low thoracic SCI (T9-T12) patients, and 10 matched able-bodied controls. SCI participants had completed their active rehabilitation at least 6 months before the study.Interventions: A balance-changing (forward) reaching task while seated in four differently configured chairs. Tilt angle (7 degrees and 12 degrees) and reclination angle (22 degrees) were varied relative to a standard chair configuration (10 degrees reclination).Main Outcome Measures: Maximal unsupported reaching distance, center-of-pressure displacement and muscle activity.Results: Although no significant difference in actively controllable reach was found in controls or in subjects with low SCI, sitting balance improved in all chairs relative to the standard chair. Ability to control displacement of arms and trunk during reaching improved. No apparent need for additional postural muscle activity was found. Persons with high SCI did not improve their sitting balance. They were unable to control a shift in body mass larger than the one induced by arm movement. However, they had less muscle activity after backrest reclination or tilting the chair backwards.Conclusions: The tested chairs had an overall positive effect. However, for individually tailored chair configurations factors other than those investigated should be considered.
