背景和目的-使用跑步机的运动训练（LT）可以改善轻偏瘫患者的步行能力，尽管提供LT所需的人员要求可能会限制其应用。机器人设备，提供一致的对称援助已被开发，以促进LT，虽然他们在改善运动能力的有效性还没有得到很好的established.Methods-Forty八个门诊慢性中风幸存者分层的严重程度运动缺陷完成了随机对照研究的影响，机器人与治疗师辅助LT。两组接受12 LT会议为30分钟，在类似的速度，使用机器人矫形器的引导对称运动辅助与使用按需辅助范例的单个治疗师的手动辅助。结果的措施，包括步态速度和对称性，活动和participation.Results的临床措施，在速度和单肢站立时间受损leg观察到更大的改善，在受试者谁接受治疗师辅助LT，与较大的速度改善那些不太严重的步态缺陷。身体限制对生活质量的影响的感知评级的改善，只有在严重的步态缺陷谁收到治疗师辅助LT的主题。结论治疗师辅助LT有利于更大的改善步行能力在步行中风幸存者相比，一个类似的剂量的机器人辅助LT。
Background and Purpose-Locomotor training (LT) using a treadmill can improve walking ability over conventional rehabilitation in individuals with hemiparesis, although the personnel requirements often necessary to provide LT may limit its application. Robotic devices that provide consistent symmetrical assistance have been developed to facilitate LT, although their effectiveness in improving locomotor ability has not been well established.Methods-Forty-eight ambulatory chronic stroke survivors stratified by severity of locomotor deficits completed a randomized controlled study on the effects of robotic-versus therapist-assisted LT. Both groups received 12 LT sessions for 30 minutes at similar speeds, with guided symmetrical locomotor assistance using a robotic orthosis versus manual facilitation from a single therapist using an assist-as-needed paradigm. Outcome measures included gait speed and symmetry, and clinical measures of activity and participation.Results -Greater improvements in speed and single limb stance time on the impaired leg were observed in subjects who received therapist-assisted LT, with larger speed improvements in those with less severe gait deficits. Perceived rating of the effects of physical limitations on quality of life improved only in subjects with severe gait deficits who received therapist-assisted LT.Conclusions-Therapist-assisted LT facilitates greater improvements in walking ability in ambulatory stroke survivors as compared to a similar dosage of robotic-assisted LT.
