The aim of the present study was to analyze the effects of whole-body vibration on lower limb muscle architecture, muscle strength, and balance in stroke patients during a period of 3 mos.
The inclusion criteria were having had ischemic or hemorrhagic stroke at least 6 mos before the study and a National Institutes of Health Stroke Scale score of greater than 1 and less than 20. The patients were randomly divided into two groups: an experimental group (n = 11, six men and five women; age, 62.4 ± 10.7 yrs; height, 1.64 ± 0.07 m; mass, 69.4 ± 12.9 kg) and a sham group (n = 9, five men and four women; age, 64.4 ± 7.6 yrs; height, 1.62 ± 0.07 m; mass, 75.0 ± 15.8 kg). The experimental group received a whole-body vibration treatment, with an increase in frequency, sets, and time per set during 17 sessions. The sham group performed the same exercises as that of the experimental group but was not exposed to vibration. Outcome variables included the muscle architecture (the rectus femoris, the vastus lateralis, and the medial gastrocnemius), the maximal isometric voluntary contraction of the knee extensors, and the Berg Balance Scale.
There were no significant differences between the groups on the primary outcomes of lower limb muscle architecture, muscle strength, and balance.
It seems that whole-body vibration exercise does not augment the increase in neuromuscular performance and lower limb muscle architecture induced by isometric exercise alone in stroke patients.
本研究旨在分析全身振动对下肢肌肉结构、肌肉力量和平衡的影响，在 3 个月的时间内对脑卒中患者进行治疗。
纳入标准为在研究前至少 6 个月发生缺血性或出血性脑卒中，且美国国立卫生研究院卒中量表评分大于 1 分且小于 20 分。患者被随机分为两组：实验组（n = 11，6 男 5 女；年龄 62.4 ± 10.7 岁；身高 1.64 ± 0.07 m；体重 69.4 ± 12.9 kg）和假手术组（n = 9，5 男 4 女；年龄 64.4 ± 7.6 岁；身高 1.62 ± 0.07 m；体重 75.0 ± 15.8 kg）。实验组接受全身振动治疗，在 17 次治疗中逐渐增加频率、组数和每组时间。假手术组进行与实验组相同的运动，但不接受振动。主要观察指标包括股直肌、股外侧肌和腓肠肌的肌肉结构、膝关节伸肌的最大等长随意收缩力和 Berg 平衡量表。
两组下肢肌肉结构、肌肉力量和平衡的主要结果无显著差异。
全身振动运动似乎不会增强单独等长运动引起的脑卒中患者神经肌肉性能和下肢肌肉结构的增加。
