Muscle weakness in the lower limbs is a motor consequence of stroke that causes functional impairment. The aim of this study was to assess the effectiveness of an individualized isokinetic strengthening programme, using the moment-velocity profile, on functional recovery during post-stroke rehabilitation of older patients. A further objective was to describe the effects of the individualized isokinetic strengthening on muscular parameters.
Retrospective study.
Older post-stroke patients.
Using the Barthel Index, functional abilities in basic daily tasks were assessed and retrospectively analysed for 88 patients in a post-stroke rehabilitation unit. Of these, 44 patients received conventional rehabilitation (conventional group) and 44 received individualized isokinetic strengthening in addition to conventional rehabilitation (isokinetic group). A 2-Group (isokinetic, conventional) × 2-Time (before, after intervention) repeated measures analysis of variance (ANOVA) was conducted. For muscular parameters, Student t-tests and Wilcoxon tests were performed.
The Barthel Index score increased more in the isokinetic group (61.59 ± 26.34 to 88.18 ± 12.16) than in the conventional group (61.70 ± 26.5 to 76.93 ± 18.12). A significant Time × Group interaction was found (F(1,86) = 5.95, p = 0.02). In the isokinetic group all muscular parameters improved.
This retrospective clinical study suggests that lower limb isokinetic strengthening, individualized using the moment-velocity profile, is clinically efficient for functional recovery during post-stroke rehabilitation of older patients. Intragroup effects of isokinetic strengthening also suggest benefits for muscular parameters.
下肢肌肉无力是中风的运动后果，导致功能障碍。本研究旨在评估使用力矩-速度曲线的个体化等速强化方案对老年脑卒中患者康复后功能恢复的有效性。另一个目的是描述个体化等速强化对肌肉参数的影响。
回顾性研究。
老年脑卒中患者。
使用巴氏指数（Barthel Index）评估基本日常生活活动能力，并对脑卒中康复病房的 88 例患者进行回顾性分析。其中 44 例接受常规康复（常规组），44 例在常规康复的基础上接受个体化等速强化（等速组）。采用 2 组（等速组、常规组）×2 时间（干预前、干预后）重复测量方差分析（ANOVA）进行分析。对于肌肉参数，采用学生 t 检验和 Wilcoxon 检验进行分析。
等速组的巴氏指数评分增加更多（61.59±26.34 至 88.18±12.16），常规组增加较少（61.70±26.5 至 76.93±18.12）。发现时间×组间存在显著交互作用（F(1,86)=5.95，p=0.02）。在等速组中，所有肌肉参数均得到改善。
这项回顾性临床研究表明，使用力矩-速度曲线个体化的下肢等速强化对老年脑卒中患者康复后功能恢复具有临床效果。等速强化的组内效应也表明对肌肉参数有益。
