本研究调查了两名脊髓损伤（SCI）患者使用功能性神经肌肉刺激（FNS）站立时改变足部位置的效果，并与一名身体健全的受试者组进行了比较。FNS辅助的站立者根据需要使用双杠进行支撑，而身体健全的组不用手站立。三种不同的脚放置进行了测试：并排，宽，修改串联。对于SCI受试者，脚上负载的体重百分比并没有受到脚放置的很大影响，这可能会在功能任务期间改变姿势以提供姿势益处。前/后（A/P）中心的压力（COP）的起源往往位于更前面的基础上的支持SCI的科目相比，健全的科目。SCI受试者的内侧/外侧（M/L）COP偏移也往往大于健全受试者。骶骨作为监测前后姿势摇摆的传感器位置似乎有一定的希望，但M/L方向的运动不一致，需要进一步研究。一般的指导方针，如定位A/P COP更后方的基础上的支持和反馈有关过度M/L COP位移可能是有用的，以提高常设性能SCI科目。此外，改良串联放置是一种有效的替代姿势调整的SCI受试者谁经历了过度的右膝屈曲与其他脚的位置。
This study investigated the effects of altering foot placement for two individuals with spinal cord injuries (SCI) that stood using functional neuromuscular stimulation (FNS) as compared to an able-bodied subject group. FNS-assisted standers used parallel bars as needed for support, while the able-bodied group stood hands-free. Three different foot placements were tested: side-by-side, wide, and modified tandem. For SCI subjects, the percentage of body weight loaded on the feet was not greatly affected by foot placement, which potentially could be altered to provide postural benefits during functional tasks. Anterior/posterior (A/P) center of pressure (COP) origins tended to be located more anterior in the base of support for SCI subjects as compared to able-bodied subjects. SCI subjects also tended to have medial/lateral (M/L) COP excursions that were larger than able-bodied subjects. The sacrum appeared to hold some promise as a sensor location for monitoring A/P postural sway, but movements in the M/L direction were inconsistent and will require additional study. General guidelines such as positioning the A/P COP more posterior in the base of support and feedback concerning excessive M/L COP displacements may be useful to improve standing performance for SCI subjects. In addition, the modified tandem placement was an effective alternative for making postural adjustments in one SCI subject who experienced excessive right knee flexion with other foot placements.
