To examine the effectiveness of task-oriented progressive resistance strength training on lower extremity strength and functional performance in chronic stroke subjects.
Single-blind, randomized controlled trial.
Medical centre and district hospital.
Forty-eight subjects at least one year post stroke.
Participants randomly allocated to two groups, control (n-/24) and experimental (n-/24). Subjects in the control group did not receive any rehabilitation training. Subjects in the experimental group were put on a four-week task-oriented progressive resistance strength training.
Lower extremity muscle strength, gait velocity, cadence, stride length, six-minute walk test, step test, and timed up and go test.
Muscle strength significantly improved in the experimental group for strong side muscle groups (ranged from 23.9% to 36.5%) and paretic side muscle groups (ranged from 10.1% to 77.9%). In the control group muscle strength changes ranged from 6.7% gain to 11.2% decline. The experimental group showed significant improvement in all selected measures of functional performance except for the step test. In the control group, the number of repetitions of the step test significantly decreased (-20.3%) with no change in other functional tests. There was a significant difference between groups for muscle strength and all functional measures. The strength gain was significantly associated with gain in the functional tests.
The task-oriented progressive resistance strength training programme could improve lower extremity muscle strength in individuals with chronic stroke and could carry over into improvement in functional abilities.
探讨任务导向渐进性抗阻力量训练对慢性卒中患者下肢力量及功能表现的有效性。
单盲随机对照试验。
医疗中心和地区医院。
48名卒中后至少一年的患者。
参与者随机分为两组，对照组（n = 24）和试验组（n = 24）。对照组患者未接受任何康复训练。试验组患者接受为期四周的任务导向渐进性抗阻力量训练。
下肢肌肉力量、步速、步频、步幅、6分钟步行试验、台阶试验及计时起立行走试验。
试验组健侧肌肉群力量显著改善（提高幅度为23.9%至36.5%），患侧肌肉群力量也显著改善（提高幅度为10.1%至77.9%）。对照组肌肉力量变化范围为增加6.7%至下降11.2%。试验组除台阶试验外，所有选定的功能表现指标均显著改善。对照组台阶试验重复次数显著减少（-20.3%），其他功能测试无变化。两组在肌肉力量和所有功能指标上存在显著差异。力量增加与功能测试中的改善显著相关。
任务导向渐进性抗阻力量训练方案可改善慢性卒中患者的下肢肌肉力量，并可转化为功能能力的提高。
