In hemiparetic patients, the skeletal muscle is mainly affected with a combination of abnormalities (denervation, remodeling, spasticity, and eventually muscular atrophy).
This study examined the role of eccentric exercise in strengthening muscles of the lower extremity and ultimately improving autonomy in patients with post-stroke hemiparesis during gait.
Thirty-seven patients hemiparetic adults were recruited, randomized into a control group (n = 19) and an intervention group receiving eccentric muscle strengthening (n = 18). The protocol consisted of three sets of five repetitions of eccentric contraction of the paretic limb after determining the maximum repetition (1 MRI). Evaluation of the 1RM, 10 meters and 6WMT was performed before and after the exercise for each group. Manova test was used to compare the differences between the control and intervention groups.
The paretic limb showed significant increase in one-repetition maximum (1RM) between before and after rehabilitation (p≤0.00003). The two groups of Patients increased their walking speed (p≤0.0005), but we observed a significant difference between groups only for the 6MWT and not on the 10 meters Test.
Eccentric training can be useful in strengthening the muscles of the lower limbs, and promoting gait performance. Eccentric training could complement other methods of managing patients with post-stroke hemiparesis.
在偏瘫患者中，骨骼肌肉主要受到异常的影响（去神经支配、重塑、痉挛，最终导致肌肉萎缩）。
本研究探讨了离心运动在强化下肢肌肉以及最终改善脑卒中后偏瘫患者步态自主能力方面的作用。
共招募了 37 名偏瘫成年患者，随机分为对照组（n=19）和接受离心肌肉强化干预组（n=18）。方案包括在确定最大重复次数（1MRI）后对患侧肢体进行五组、每组五次的离心收缩。在每组患者进行锻炼前后，进行 1RM、10 米和 6WMT 的评估。使用 Manova 检验比较对照组和干预组之间的差异。
患侧肢体的最大重复次数（1RM）在康复前后均有显著增加（p≤0.00003）。两组患者的行走速度都有所提高（p≤0.0005），但我们仅观察到 6MWT 组之间存在显著差异，而 10 米测试则没有。
离心训练可以有效增强下肢肌肉力量，提高步态表现。离心训练可以作为管理脑卒中后偏瘫患者的其他方法的补充。
