目的:研究膝关节等速肌力训练对脑梗死偏瘫患者步行功能恢复的作用。方法:选取预后能恢复至社区性步行的早期脑梗死偏瘫患者作为研究对象,随机分为观察组和对照组,每组80人;对照组进行常规的系统康复治疗,观察组在对照组的基础上增加患侧膝关节的等速肌力训练;患者进入系统治疗前后采用Fugl-Meyer下肢运动功能评分、Berg平衡量表进行评定,治疗后评定10 m最大步行速度。结果:经过1周的系统治疗,两组患者的Fugl-Meyer评分、Berg评分、10 m最大步行速度比较差异无统计学意义(P>0.05)。结论:对于预后能恢复至社区性步行的早期脑梗死偏瘫患者,在接受常规系统康复治疗的同时,增加患侧膝关节的等速肌力训练,对步行能力的改善未见进一步获益。
Objective: To study the effect of isokinetic knee strength training on the recovery of walking function in hemiparetic patients with cerebral infarction. Methods: Patients with hemiplegia of early cerebral infarction whose prognosis could be recovered to community walk were randomly divided into observation group and control group, with 80 in each group. The control group received routine systematic rehabilitation, and the observation group was basal in the control group On the other hand, the isokinetic strength training of the ipsilateral knee joint was increased. The Fugl-Meyer lower extremity motor function score and the Berg balance scale were used before and after the treatment. The maximum walking speed of 10 m was evaluated after the treatment. Results: After one week of systemic treatment, there was no significant difference in Fugl-Meyer score, Berg score and maximum walking speed of 10 m between the two groups (P> 0.05). CONCLUSIONS: For patients with hemiplegia of early stage of cerebral infarction whose prognosis can be restored to community-based walking, increasing isokinetic strength training of the affected side knees while receiving conventional systematic rehabilitation does not further benefit the improvement of walking ability.
