The aim of this study was to investigate the use of functional electrical stimulation (FES) as a means of pressure sore prevention in seated spinal cord injured (SCI) subjects. Nine SCI subjects took part in tests in which electrical stimulation was applied to the quadriceps with the lower legs restrained. Ischial pressures were measured during periods of quiet sitting and FES application. A strain gauged lever arm was used to measure the knee moment during quadriceps stimulation. The average pressure drop at the right and left buttocks was 44 mmHg and 27 mmHg respectively. In general the greatest reductions occurred in subjects with larger knee moments; however, there was no direct relationship between the pressure reduction obtained and the quadriceps strength. This form of FES may be useful as a prophylactic aid in the management of pressure sores in SCI subjects.
本研究的目的是调查功能性电刺激（FES）作为预防脊髓损伤（SCI）坐姿患者压疮的一种手段的应用情况。九名脊髓损伤患者参与了测试，测试过程中在小腿被固定的情况下对股四头肌施加电刺激。在安静坐姿和施加功能性电刺激期间测量坐骨压力。使用应变片杠杆臂测量股四头肌刺激期间的膝关节力矩。左右臀部的平均压力下降分别为44 mmHg和27 mmHg。一般来说，膝关节力矩较大的患者压力下降最大；然而，获得的压力降低与股四头肌力量之间没有直接关系。这种形式的功能性电刺激可能作为预防脊髓损伤患者压疮的一种辅助手段。
