Reduction of muscle strength and lean mass, increase in the risk of falls, higher mortality, and morbidity are observed in geriatric syndromes. Physical activity is an effective intervention in reducing signs and symptoms of geriatric syndromes. Whole-body vibration exercise (WBVE) is an intervention with low cost and has been effective.
The aim of this systematic review aimed to determine the effects of WBVE on neuromuscular activation and muscle strength in the elderly. Searches in PubMed, Embase, Science direct, and Scopus databases were conducted. Six studies, that analyzed the use of surface electromyography evaluating effects of WBVE on neuromuscular activation and muscle strength in the elderly, published in English, were included.
Six studies were included. One hundred forty-six individuals participated in the studies and 24 were males (16.43%), with an average age of 74.20 ± 7.66 years. Five publications were defined as "fair" methodological in the PEDro scale, the risk of bias was high and the risk of bias for non-randomized studies was moderate/high. In general, increased strength muscle was reported in the studies.
This systematic review suggests that WBVE might promote desirable neuromuscular responses in healthy elderly. However, it is necessary to perform further studies to reinforce the reported findings.IMPLICATIONS FOR REHABILITATIONThe reduction in lean mass and consequent reduction in muscle strength are present in healthy elderly people and the whole-body vibration exercise can reduce or alleviate these symptoms caused by the geriatric syndrome.Whole-body vibration exercise is a training modality that increases neuromuscular activation and muscle strength.Surface electromyography is a useful tool for the evaluation of the neuromuscular activation of the muscle fibers.
在老年综合征中观察到肌肉力量和瘦体重减少、跌倒风险增加、死亡率和发病率更高。身体活动是减少老年综合征体征和症状的有效干预措施。全身振动训练（WBVE）是一种成本低且有效的干预措施。
本系统评价的目的是确定全身振动训练对老年人神经肌肉激活和肌肉力量的影响。在 PubMed、Embase、Science Direct 和 Scopus 数据库中进行了检索。纳入了 6 项研究，这些研究使用表面肌电图分析了全身振动训练对老年人神经肌肉激活和肌肉力量的影响，均为英文发表。
纳入了 6 项研究。146 名个体参与了这些研究，其中 24 名是男性（16.43%），平均年龄为 74.20±7.66 岁。PEDro 量表中，有 5 项研究被定义为“中等”方法学质量，偏倚风险高，非随机研究的偏倚风险为中度/高度。总体而言，研究报告称肌肉力量增强。
本系统评价表明，全身振动训练可能会促进健康老年人的理想神经肌肉反应。然而，有必要进行进一步的研究来加强报告的发现。
瘦体重减少和随之而来的肌肉力量下降在健康老年人中很常见，全身振动训练可以减少或缓解老年综合征引起的这些症状。全身振动训练是一种增加神经肌肉激活和肌肉力量的训练方式。表面肌电图是评估肌肉纤维神经肌肉激活的有用工具。
