[目的]评价功能性电刺激（FES）治疗脑卒中患者的疗效。[受试者]招募了9名（男性=6，女性=3）中风患者。他们都处于亚急性期。[方法]根据FES治疗体位将受试者分为站立位组和仰卧位组。两组均采用FES治疗，每次30 min，每周6次，共治疗8周。每2周对受试者进行一次评估，持续8周，使用定时起立-行走试验（TUG）。贝格平衡试验（BBT）和FES强度，以诱导最大肌肉收缩。[结果] TUG和BBT评定结果显示，站立组的平衡能力较仰卧组有明显改善。8周后，站立组的TUG时间从30.25 +/- 5.0显著缩短至20.73 +/- 3.9，仰卧组从31.99 +/- 3.6显著缩短至26.40 +/- 4.5。8周后，站立组的BBT评分从28.0 +/- 8.8显着增加到45.6 +/- 5.9，仰卧组从26.25 +/- 5.9显着增加到37.5 +/- 3.7。8周后，站立组的FES强度从48.4 +/- 12.4 mA显著变化为36.8 +/- 11.9 mA，仰卧组从48.8 +/- 13.5 mA显著变化为43.75 +/- 11.8 mA。[结论]站立位比仰卧位更有利于脑卒中后平衡能力的恢复。
[Purpose] The present study was designed to evaluate the effect of functional electrical stimulation (FES) according to the treatment position (standing and supine) on patients after stroke. [Subjects] Nine (men=6, women=3) patients who had suffered from stroke were recruited. They were all in their subacute stage. [Methods] Participants were divided into 2 groups according to the position for treatment by FES (standing group and supine group). The duration of FES in both groups was 30 minutes, 6 times a week for 8 weeks. The subjects were evaluated every 2 weeks for 8 weeks using the timed up-and-go test (TUG). Berg balance test (BBT) and FES intensity to induce maximum muscle contraction. [Results] The standing group showed greater improvements in balance ability than the supine group as assessed by TUG and BBT. The time of TUG was significantly reduced from 30.25 +/- 5.0 to 20.73 +/- 3.9 in the standing group and from 31.99 +/- 3.6 to 26.40 +/- 4.5 in the supine group after 8 weeks. The scores of BBT significantly increased from 28.0 +/- 8.8 to 45.6 +/- 5.9 in the standing group and from 26.25 +/- 5.9 to 37.5 +/- 3.7 in the supine group after 8 weeks. The FES intensity significantly changed from 48.4 +/- 12.4 mA to 36.8 +/- 11.9 mA in the standing group and from 48.8 +/- 13.5 mA to 43.75 +/- 11.8 mA in the supine group after 8 weeks. [Conclusion] These results suggest that the standing position is more beneficial to the recovery of balance ability after stroke than the supine position.
