目的：评估体重支持（BWS）、功能性电刺激（FES）和踏车训练相结合的干预对地上步行速度（OGWS）、踏车步行速度、速度和距离以及下肢运动评分（LEMS）的影响。设计：前后比较。设置：迈阿密治疗瘫痪项目。参与者：19名受试者与美国脊髓损伤协会C级损伤谁是至少1年postinjury和不对称lower limb function.Intervention：受试者训练1.5小时，每天，每周3天，3个月。训练包括体重支持的踏车步行辅助电刺激。刺激施加到腓总神经的较弱的下肢（LE）和定时，以协助摆动阶段的步骤cycle.Main Outcome Measures：OGWS在没有BWS和FES; LEMS，和跑步机训练参数的速度和距离。在培训过程中，OGWS显著增加，（从0.12 +/- 0.8m/s到0.21 +/-0.15m/s，p = 0.008），跑步机行走速度（从0.23 +/- .12m/s到0.49 +/- .20m/s，p = 0.00003）和跑步机步行距离（从93 +/-84 m到243 +/-139 m，p = 0.00001）。刺激和非刺激腿的中位LEMS均显著增加（FES辅助腿从8增加到11，非辅助腿从15增加到18，p <0.005）。需要进一步的研究来描述这些特定培训策略的基本要素。
Objective: To assess the effect of an intervention combining body weight support (BWS), functional electric stimulation (FES), and treadmill training on overground walking speed (OGWS), treadmill walking speed, speed and distance, and lower extremity motor scores (LEMS).Design: Before and after comparison.Setting: Miami Project to Cure Paralysis.Participants: Nineteen subjects with American Spinal Injury Association class C injury who were at least 1 year postinjury and had asymmetrical lower extremity function.Intervention: Subjects trained 1.5 hours per day, 3 days per week, for 3 months. The training consisted of body weight-supported treadmill walking assisted by electric stimulation. Stimulation was applied to common peroneal nerve of the weaker lower extremity (LE) and timed to assist with the swing phase of the step cycle.Main Outcome Measures: OGWS in the absence of both BWS and FES; LEMS, and treadmill training parameters of speed and distance.Results: Over the course of training, there was a significant increase in OGWS (from .12 +/- 0.8m/s to .21 +/- .15m/s, p = .008), treadmill walking speed (from .23 +/- .12m/s to .49 +/- .20m/s, p = .00003), and treadmill walking distance (from 93 +/- 84m to 243 +/- 139m, p = .000001). The median LEMS increased significantly for both the stimulated and nonstimulated leg (from 8 to 11 in the FES-assisted leg, from 15 to 18 in the nonassisted leg, p < .005 for each).Conclusions: All subjects showed improvement in OGWS and overall LE strength. Further research is required to delineate the essential elements of these particular training strategies.
