目的：确定步态训练 (GT) 机是否影响偏瘫患者的步行时间和耗氧量。设计：重复测量并比较 2 组。地点：康复医院的生理实验室。参与者：7 名中风相关偏瘫患者（2 名男性，5 名女性；年龄，46 +/- 1 1 年；中风后时间，12 +/- 9 周）和 7 名健康受试者（3 名男性，4 名）干预措施：地板行走 (FW) 和有或没有 50% 体重支撑 (BWS) 的 GT 辅助行走。主要结果指标：行走时间、耗氧量 (Vo(2))、每分钟通气量 (VE) 和心率。结果：从组中独立分析状况影响时，FW 测试期间的平均 Vo(2) 高于 GT 测试期间（事后分析：FW 与 GT 相比， P=.017 FW 与 GT+BWS，P；
Objective: To determine whether a gait-training (GT) machine influenced walking time duration and oxygen consumption in hemiplegic patients.Design: Repeated measures with comparison of 2 groups.Setting: Physiology laboratories in a rehabilitation hospital.Participants: Seven patients with stroke-related hemiplegia (2 men, 5 women; age, 46 +/- 1 1y; time since stroke, 12 +/- 9wk) and 7 healthy subjects (3 men, 4 women; age, 30 +/- 7y).Interventions: Floor walking (FW) and GT-assisted walking with and without 50% body-weight support (BWS).Main Outcome Measures: Walking time duration, oxygen consumption (Vo(2)), minute ventilation (VE), and heart rate.Results: When the condition effect was analyzed independently from the group, mean Vo(2) was higher during FW than during the GT tests (post hoc analysis: FW vs GT, P=.017; FW vs GT+BWS, P
