目的：越来越多的证据表明，机器人辅助的跑步机训练可能有助于脑卒中后的步态康复。本研究的目的是评估中风患者在机器人辅助行走和地上行走过程中的肌肉活动，以及一组身体健全的受试者在地上行走过程中的肌肉活动。设计：病例对照观察研究。受试者：10名中风受试者和10名身体健全的对照受试者。方法：在3项试验中对7块下肢肌肉进行肌电图测量：机器人行走，其中中风受试者在机器人辅助的步态矫形器中行走;同一组中风受试者的地上行走;以及对照受试者的地上行走。试验进行了比较，就选择腿部肌肉的肌电图振幅。结果：在地上行走与机器人行走相比，发现在几个肌肉在几个阶段的步态周期中的肌肉活动更高。一个显着的试验x腿的相互作用揭示了较小的差异，在机器人行走过程中，与地上行走的肌肉活动之间的麻痹和非麻痹腿。此外，控制行走和机器人行走之间的肌肉活动模式没有显着差异，而控制行走和地上walking.Conclusion：尽管较低的肌肉活动，机器人辅助跑步机训练可能会引起一个更对称的模式，腿部肌肉活动，这接近健全的个人。
Objective: There is increasing evidence that robot-assisted treadmill training might be useful for gait rehabilitation after stroke. The aim of this study was to evaluate the muscle activity of stroke patients during robot-assisted walking and overground walking, and of a group of able-bodied subjects during overground walking.Design: Case-control observational study.Subjects: Ten stroke subjects and 10 able-bodied control subjects.Methods: Electromyography measurements of 7 lower-limb muscles were made in 3 trials: robotic walking, in which stroke subjects walked in a robot-assisted gait orthosis; overground walking for the same group of stroke subjects; and overground walking for control subjects. Trials were compared with respect to electromyography amplitude of selected leg muscles.Results: Higher muscle activity during overground walking compared with robotic walking was found in several muscles during several phases of the gait cycle. A significant trial x leg interaction revealed smaller differences in muscle activity between the paretic and non-paretic leg during robotic walking compared with overground walking. Furthermore, the muscle activity pattern was not significantly different between control walking and robotic walking, while it was different between control walking and overground walking.Conclusion: Despite lower muscle activity, robot-assisted treadmill training may elicit a more symmetrical pattern of leg muscle activity, which approaches that of able-bodied individuals.
