目的：研究座椅倾斜对胸椎脊髓损伤 (SCI) 患者骨盆倾斜、平衡控制和姿势肌肉使用的影响。设计：横断面小组研究。地点：康复中心和康复医院科室。患者：10 名完全性高胸段 SCI（T2-8 级）患者、10 名完全低胸段 SCI（T9-12 级）患者和 10 名匹配的健全人干预：座椅前倾 10 度。主要结果测量：骨盆倾斜、压力中心位移和肌肉活动。结果：无论是否患有 SCI 患者，都无法显示因座椅前倾而导致的骨盆前倾。平衡控制不受座椅前倾的影响。当参与者坐在前倾座椅上时，他们的整体肌肉活动下降。结论：运动学和肌电图数据提供的证据不足以制定基于骨盆定位的轮椅处方方案。
Objective: To study the effect of seat tilting on pelvic tilt, balance control, and postural muscle use in persons with a thoracic spinal cord injury (SCI).Design: Cross-sectional group study.Setting: Rehabilitation centers and rehabilitation hospital departments.Patients: Ten complete high thoracic SCI (level T2-8) patients, 10 complete low thoracic SCI (level T9-12) patients, and 10 matched able-bodied controls.Intervention: A 10 degrees forward inclination of the seat.Main Outcome Measures: Pelvic tilt, center of pressure displacement, and muscle activity.Results: Anterior tilting of the pelvis as a result of forward inclination of the seat could not be shown, either in persons with or without SCI. Balance control was not influenced by forward inclination of the seat. Participants' overall muscle activity decreased while they were seated in the chair with the forwardly inclined seat.Conclusions: Evidence provided by the kinematic and electromyographic data is not sufficient to develop a protocol for wheelchair prescription on the basis of pelvic positioning.
