Foot drop affects walking in people with multiple sclerosis (pwMS). This study compares the initial orthotic effects of two treatments for foot drop: ankle-foot orthoses (AFO) and functional electrical stimulation (FES), on the speed and oxygen cost of walking in MS.
Seventy-eight pwMS were randomised to receive AFO or FES (ODFS PACE (OML, Salisbury, UK)). Participants completed the 25-ft walk test (25ftWT) and 5-min self-selected walk test (5minSSWT), from which oxygen cost was determined, with and without their device. Between-, within- and sub-group analyses (based on baseline walking speed of <0.8 m/s (slow) or ≥0.8 m/s (fast)) were undertaken.
No significant differences between baseline measures were observed. The AFO group walked significantly slower than the FES group (5minSSWT, = 0.037, 0.11 m/s). The AFO group walked significantly slower with than without AFO (25ftWT, = 0.037), particularly in the fast-walking group ( = 0.011). The slow-walking FES group walked significantly faster with FES than without (25ftWT; = 0.029, 5minSSWT; = 0.037). There were no differences in the fast-walking FES group or in the oxygen cost for either device.
AFO reduced walking speed, particularly in fast walkers. FES increased walking speed in slow, but not fast walkers.
足下垂会影响多发性硬化症患者（pwMS）的行走。本研究比较了两种足下垂治疗方法的初始矫形效果：踝足矫形器（AFO）和功能性电刺激（FES），对多发性硬化症患者行走速度和氧气消耗的影响。
78名pwMS患者被随机分配接受AFO或FES（ODFS PACE，英国索尔兹伯里OML公司）。参与者完成25英尺步行测试（25ftWT）和5分钟自选步行测试（5minSSWT），在佩戴和不佩戴其设备的情况下测定氧气消耗。进行了组间、组内和亚组分析（基于基线步行速度<0.8米/秒（慢）或≥0.8米/秒（快））。
未观察到基线测量之间的显著差异。AFO组的行走速度明显慢于FES组（5minSSWT，P = 0.037，0.11米/秒）。AFO组佩戴AFO时的行走速度明显慢于不佩戴时（25ftWT，P = 0.037），特别是在快走组（P = 0.011）。慢走的FES组佩戴FES时的行走速度明显快于不佩戴时（25ftWT；P = 0.029，5minSSWT；P = 0.037）。快走的FES组或两种设备的氧气消耗均无差异。
AFO降低了行走速度，尤其是在快走者中。FES提高了慢走者的行走速度，但对快走者没有效果。
