背景/目的：运动功能障碍是中风患者的常见问题，并且关于振动疗法在神经系统患者中的应用仍然存在许多问题。本研究旨在验证振动训练对中风患者下肢功能的影响。方法：这是一项临床前瞻性研究。该研究的受试者是通过巴西波苏阿莱格里塞缪尔利巴尼奥医院物理治疗和神经科门诊的方便样本选择的。该样本由 27 名因中风而出现痉挛性偏瘫的个体组成。参与者接受频率为 50 Hz、幅度为 2 mm 的全身振动训练，为期 8 周。在前 4 周内，参与者以以下姿势进行一系列 4 次 60 秒的振动周期：在直立姿势下，首先将膝盖半弯曲 30 度，然后将膝盖半弯曲 90 度，然后将受影响的膝盖半弯曲 30 度，最后再次保持直立姿势，将膝盖半弯曲 30 度。在过去的 4 周中，我们将振动系列的数量增加了一倍，但使用了相同的位置。采用六分钟步行测试（6MWT）、爬楼梯测试（SCT）和定时起立行走测试（TUG）来评估下部成员的运动功能。在干预前后以及1个月后的随访后进行测试。结果：本研究发现6MWT（P=0.00）、SCT（P=0.00）和TUG（P=0.00）有统计学差异，表明参与者的下肢运动功能得到改善。结论：振动疗法有助于脑卒中患者下肢运动功能的改善。
Background/aim: Motor function impairment is a frequent problem in stroke patients and many questions remain about the application of vibration therapy for neurological patients. This study aims to verify the effects of vibration training on lower limb function in patients affected by stroke.Methods: This was a clinical, prospective study. The study's subjects were selected via a convenience sample from Samuel Libanio Hospital's Physical Therapy and Neurology Out-patient clinics in Pouso Alegre, Brazil. The sample comprised of 27 individuals presenting with spastic hemiparesis due to stroke. Participants received whole body vibration training at a frequency of 50 Hz and 2 mm amplitude, for 8 weeks. In the first 4 weeks, participants underwent a series of four 60-second periods of vibration in the following positions: in orthostatic posture, first with the knees semi-flexed at 30 degrees, then with the knees semi-flexed at 90 degrees, and then with the affected knee semi-flexed at 30 degrees, and finally in orthostatic posture again with the knees semi-flexed at 30 degrees. In the last 4 weeks, we doubled the number of series of vibration, but used the same positions. The six minute walking test (6MWT), the stair climbing test (SCT) and the timed get up and go test (TUG) were applied to evaluate the lower members' motor function. The tests were applied before and after the intervention, as well as after a follow-up, which was performed 1 month later.Results: This study found statistical differences in the 6MWT (P=0.00), SCT (P=0.00), and TUG (P=0.00), indicating improvement in the participants' lower limbs motor function.Conclusion: Vibration therapy can contribute to the improvement of the lower limbs' motor function in patients affected by stroke.
