研究了23例慢性脑卒中患者全身振动对体位控制的短期影响。当患者站在商业平台上时，在额平面接受振幅为3mm的30hz振荡。使用双板力平台评估平衡性，每隔45分钟评估四次，同时静静地站着，睁开或闭上眼睛，同时在压力中心运动的视觉反馈下进行自愿的体重转移任务。在第二次和第三次评估之间，给予四次45秒的全身振动。结果表明，从第一次评估到第二次评估，所有任务的基准表现都是稳定的。全身振动后，第三次评估显示闭眼站立时前后方向的均方根（RIMS）压心速度降低（P < 0.01），这种情况在第四次评估中持续存在。此外，患者在第三次平衡评估时的体重转移速度有所增加（P < 0.05），而其精度保持不变。未观察到全身振动的不良反应。综上所述，全身振动可能是改善脑卒中患者本体感觉控制的一个有希望的候选人。
The short-term effects of whole-body vibration as a novel method of somatosensory stimulation on postural control were investigated in 23 chronic stroke patients. While standing on a commercial platform, patients received 30-Hz oscillations at 3 mm of amplitude in the frontal plane. Balance was assessed four times at 45-min intervals with a dual-plate force platform, while quietly standing with the eyes opened and closed and while performing a voluntary weight-shifting task with visual feedback of center-of-pressure movements. Between the second and third assessments, four repetitions of 45-sec whole-body vibrations were given. The results indicated a stable baseline performance from the first to the second assessment for all tasks. After the whole-body vibration, the third assessment demonstrated a reduction in the root mean square (RIMS) center-of-pressure velocity in the anteroposterior direction when standing with the eyes closed (P < 0.01), which persisted during the fourth assessment. Furthermore, patients showed an increase in their weight-shifting speed at the third balance assessment (P < 0.05) while their precision remained constant. No adverse effects of whole-body vibration were observed. It is concluded that whole-body vibration may be a promising candidate to improve proprioceptive control of posture in stroke patients.
