Whole-body vibration is a modality of exercise that uses high-frequency mechanical stimuli to enhance motor functions. Previous studies have demonstrated benefits of whole-body vibration in older adults. However, prolonged use of this modality of exercise may be detrimental to certain conditions. : to verify the acute effects of a single whole-body vibration session on mobility and postural control in community-dwelling older adults. : In this two-arm, single-blind clinical trial, fifty-two participants were randomly allocated to either the experimental (subject to a single whole-body vibration session with a vibration amplitude of 2 mm and a frequency of 40 Hz) or placebo group. The exercise sessions were conducted using a tri-planar vibration platform. The tri-plane plates were adjusted to vibrate up and down, side to side, and front to back. The assessments included mobility and postural control tests. Repeated-measures analyses of variance were performed to examine the main effect of group (experimental vs. placebo), time (baseline vs. after the intervention), and group × time interaction effect. Significance was set at 5%. : Compared with the placebo group, participants who underwent whole-body vibration showed positive outcomes in terms of mobility ( = 0.014, effect size: 0.115). Contrastingly, no significant differences were observed between the groups in terms of postural control ( > 0.05). : Benefits of a single whole-body vibration session were observed on mobility. Using whole-body vibration to improve postural control may require additional sessions. Contraindications typical of aging should be taken into account.
全身振动是一种运动方式，它利用高频机械刺激来增强运动功能。先前的研究已经证明了全身振动对老年人有益。然而，长期使用这种运动方式可能对某些情况有害。目的：验证单次全身振动对社区居住老年人的活动能力和姿势控制的急性影响。方法：在这项双臂单盲临床试验中，52名参与者被随机分配到实验组（接受一次振动幅度为2毫米、频率为40赫兹的全身振动）或安慰剂组。运动课程使用三平面振动平台进行。三平面平板被调整为上下、左右和前后振动。评估包括活动能力和姿势控制测试。进行重复测量方差分析以检验组（实验组与安慰剂组）主效应、时间（基线与干预后）以及组×时间交互效应。显著性设定为5%。结果：与安慰剂组相比，接受全身振动的参与者在活动能力方面显示出积极结果（P = 0.014，效应大小：0.115）。相反，在姿势控制方面两组之间未观察到显著差异（P > 0.05）。结论：单次全身振动对活动能力有益。使用全身振动改善姿势控制可能需要额外的课程。应考虑典型的衰老禁忌证。
