To evaluate whether leg cycling training in subjects with chronic stroke can improve cycling performance, aerobic capacity, muscle strength, and functional performance and to determine if electric stimulation (ES) to the contralateral (paretic) leg during cycling has additional effects over cycling without ES.
A randomized controlled trial, with a partial double-blind design.
A rehabilitation center.
Twelve stroke patients (range, 18-70 y), more than 5 months poststroke, with lower-extremity hemiparesis.
Subjects were randomly assigned to groups that performed cycling exercise, one with ES evoking muscle contractions and a control group with ES not evoking muscle contractions. Subjects, blinded for group assignment, trained twice a week for 6 weeks.
Changes in aerobic capacity and maximal power output, functional performance, and lower-limb muscle strength.
Aerobic capacity and maximal power output significantly increased by 13.8%+/-19.1% and 38.1%+/-19.8%, but muscle strength was not significantly enhanced after training. Functional performance improved (ie, scores on the Berg Balance Scale increased by 6.9%+/-5.8% (P=.000) and the six-minute walk test improved by 14.5%+/-14.1% (P=.035). There was no significant effect on the Rivermead Mobility Index (P=.165). Training-induced changes were not significantly different between the 2 groups. Changes in cycling performance and aerobic capacity were not significantly related to changes in functional performance.
This study showed that a short cycling training program on a semirecumbent cycle ergometer can markedly improve cycling performance, aerobic capacity, and functional performance of people with chronic stroke. The use of ES had no additional effects in this specific group of subjects with chronic stroke.
评估慢性卒中患者进行腿部骑行训练是否能改善骑行表现、有氧能力、肌肉力量和功能表现，并确定骑行过程中对患侧（瘫痪）腿进行电刺激（ES）是否比不进行ES的骑行有额外效果。
一项随机对照试验，采用部分双盲设计。
一家康复中心。
12名卒中患者（年龄范围18 - 70岁），卒中后超过5个月，下肢偏瘫。
将受试者随机分为进行骑行运动的组，一组进行能诱发肌肉收缩的ES，另一对照组进行不诱发肌肉收缩的ES。对分组不知情的受试者每周训练两次，共6周。
有氧能力和最大功率输出、功能表现以及下肢肌肉力量的变化。
有氧能力和最大功率输出显著增加，分别为13.8%±19.1%和38.1%±19.8%，但训练后肌肉力量未显著增强。功能表现有所改善（即伯格平衡量表得分增加6.9%±5.8%（P = 0.000），6分钟步行试验改善14.5%±14.1%（P = 0.035）。对Rivermead活动指数无显著影响（P = 0.165）。两组间训练引起的变化无显著差异。骑行表现和有氧能力的变化与功能表现的变化无显著相关性。
本研究表明，在半卧位自行车测力计上进行的短期骑行训练计划可显著改善慢性卒中患者的骑行表现、有氧能力和功能表现。在这一特定的慢性卒中患者群体中，使用ES没有额外效果。
