Sarcopenia, a progressive loss of muscle mass and function with advancing age, is a prevalent condition among older adults. As most older people are too frail to do intensive exercise and vibration therapy has low risk and ease of participation, it may be more readily accepted by elderly individuals. However, it remains unclear whether vibration therapy would be effective among older adults with sarcopenia. This systematic review and meta-analysis examined the effect of vibration therapy including local vibration therapy and whole-body vibration therapy, for enhancing muscle mass, muscle strength and physical function in older people with sarcopenia.
A systematic literature search was conducted in March 2019 in the following 5 electronic databases: PubMed, CINAHL, Embase, PEDro, and the Cochrane Central Register of Controlled Trials, with no restriction of language or the year of publication. Randomized controlled trials and quasi-experimental studies examining effects of vibration therapy on muscle mass, muscle strength or physical function in older adults with sarcopenia were included in this systematic review. Two reviewers independently assessed the methodological quality of the selected studies.
Of the 1972 identified studies, seven publications from six studies involving 223 participants were included in this systematic review. Five of them conducted whole-body vibration therapy, while two conducted local vibration therapy. A meta-analysis of randomized controlled studies indicated that muscle strength significantly increased after whole-body vibration therapy (SMD 0.69, 95% CI 0.28 to 1.11, I = 0%, = 0.001) and local vibration therapy (SMD 3.78, 95% CI 2.29 to 5.28, < 0.001). Physical performance measured by the sit-to-stand test and the timed-up-and-go test were significantly improved after the intervention (SMD -0.79, 95% CI - 1.21 to - 0.37, I = 0%, < 0.001) and SMD -0.83, 95% CI - 1.56 to - 0.11, I = 64%, = 0.02, respectively).
Vibration therapy could be a prospective strategy for improving muscle strength and physical performance in older adults with sarcopenia. However, due to the limited number of the included studies, caution is needed when interpreting these results. More well-designed, large sample size studies should be conducted to further explore and validate the benefits of vibration therapy for this population.
肌肉减少症是一种随着年龄增长肌肉质量和功能逐渐丧失的疾病，在老年人中普遍存在。由于大多数老年人过于虚弱而无法进行高强度运动，且振动疗法风险低、易于参与，可能更容易被老年人接受。然而，振动疗法对患有肌肉减少症的老年人是否有效仍不清楚。本系统评价和荟萃分析探讨了包括局部振动疗法和全身振动疗法在内的振动疗法对患有肌肉减少症的老年人增加肌肉质量、肌肉力量和身体功能的影响。
2019年3月在以下5个电子数据库中进行了系统的文献检索：PubMed、CINAHL、Embase、PEDro和Cochrane对照试验中央注册库，不受语言或出版年份限制。本系统评价纳入了研究振动疗法对患有肌肉减少症的老年人肌肉质量、肌肉力量或身体功能影响的随机对照试验和准实验研究。两名评价者独立评估所选研究的方法学质量。
在1972项已识别的研究中，本系统评价纳入了来自6项研究的7篇文献，涉及223名参与者。其中5项进行了全身振动疗法，2项进行了局部振动疗法。对随机对照研究的荟萃分析表明，全身振动疗法（标准化均数差0.69，95%置信区间0.28至1.11，I² = 0%，P = 0.001）和局部振动疗法（标准化均数差3.78，95%置信区间2.29至5.28，P < 0.001）后肌肉力量显著增加。干预后，通过坐立试验和计时起立行走试验测量的身体表现显著改善（标准化均数差-0.79，95%置信区间-1.21至-0.37，I² = 0%，P < 0.001）和标准化均数差-0.83，95%置信区间-1.56至-0.11，I² = 64%，P = 0.02）。
振动疗法可能是改善患有肌肉减少症的老年人肌肉力量和身体表现的一种前瞻性策略。然而，由于纳入研究的数量有限，在解释这些结果时需要谨慎。应进行更多设计良好、大样本量的研究，以进一步探索和验证振动疗法对该人群的益处。
