等速肌力训练对脑卒中患者步行能力的影响

将60例脑卒中后偏瘫患者以区组随机方法分为对照组和治疗组，对照组采用常规康复训练，治疗组在此基础上进行膝关节等速肌力训练，治疗8周。研究结果显示，治疗组膝关节屈、伸肌峰力矩较对照组有明显改善（P〈0．01），屈伸肌力量与对照组比较差异亦有统计学意义（P〈0．01），步行能力亦明显好于对照组（P〈0．01）。说明等速肌力训练可以明显改善脑卒中偏瘫患者膝关节稳定性，对步行能力也有明显的改善作用。

Effects of isokinetic training on walking ability in hemiplegic patients after stroke

A total of 60 hemiplegic patients after stroke were divided randomly into 2 groups. The control group received conventional rehabilitation training while the treatment group isokinetic training based on conventional rehabilitation training. Both groups were trained for 8 weeks. Results showed the differences of peak torque of knee flexors and extensors were significant between two groups （ P 〈 0. 01 ）. The ratio of flexion and extension showed significant difference （ P 〈 0.01 ）. The treatment group was superior to control group in walking ability （ P 〈 0. 01 ）. Therefore isokinetic training provides significant improvement in stability of knees and walking ability in hemiplegie patients after stroke.
