Whole-Body Vibration Exercise Improves the Functionality in Postmenopausal Women: A Systematic Review.

Background: Menopause is a natural phase in a woman's aging process. Menopause leads to the decrease of the estrogen levels, and in consequence the functionality worsening. Physical exercise can improve the functionality of postmenopausal woman. This review aimed to assess the effect of whole-body vibration exercise (WBVE) on the functionality of postmenopausal women. Methods: PRISMA guideline were used. Only English language were considered. Searches were conducted using relevant keywords for papers prior to Sep 16th, 2021, in Embase, Pubmed, The Cochrane Library, PED-ro, SPORTDiscus, Scopus, Web of Science and CINAHL databases. Results: Eight articles were selected to be in this systematic review. The mean score of methodological quality was moderate, the risk of bias was low for two studies, high for four studies, and unclear for two studies. The level of evidence of the studies was II. Improvements on muscle strength, jump, balance and maximum trunk flexion strength in the post menopause woman were reported. Conclusion: This systematic review demonstrated the functionality increase in postmenopausal women through WBVE. WBVE has been recommended as a non-pharmacological option relevant to postmenopausal management, helping to control the decline in bone density and symptoms related to osteoporosis and sarcopenia. However, further studies are needed to reinforce these findings.

Effects of a Single Session of Systemic Vibratory Therapy on Flexibility, Perception of Exertion and Handgrip Strength in Chronic Obstructive Pulmonary Disease Individuals: A Quasi-Experimental Clinical Trial.

BACKGROUND: Whole-body vibration exercises (WBVE), that are generated in systemic vibratory therapy (SVT), may benefit individuals with chronic obstructive pulmonary disease (COPD). This study evaluated acute effects of SVT on the flexibility, on the perception of exertion to perform the anterior trunk flexion (ATF), and on the handgrip strength (HG). METHODS: Thirty-eight individuals, separated into two groups, performed a single session of SVT (five bouts, 25 Hz, 2.5 of amplitude) on a side-alternating vibrating platform (SAVP), in two postures: sitting (Sitting group-SitG, n = 21) or standing (Stand group-StandG, n = 17). In both positions, the feet were on the base of the SAVP. The HG and the AFT were performed before and after the session, and the perception of effort (RPE) was measured during the ATF. RESULTS: The ATF in the SitG (p ≤ 0.05) and in the StandG (p ≤ 0.05) was significantly improved, but in the comparison between both groups, no significant reduction was found (p = 0.14). The RPE was not influenced by the session. A significant increase of the HG in StandG post session (33.49 ± 10.30 kgf) p = 0.03 was found, but not in the SitG (p = 0.12) or between the two groups (p = 0.55). CONCLUSIONS: SVT, in a single acute session, would be capable of promoting some functional benefits for the COPD individuals without altering the perception of exertion to perform the ATF.

Therapeutic Approach of Whole-Body Vibration Exercise on Wound Healing in Animal Models: A Systematic Review.

Human skin wounds pose a gathering threat to the public health, carrying an immense epidemiologic and financial burden. Pharmacological and non-pharmacological (NP) treatments have been proposed to the management of wound healing. Physical exercise is a strong NP intervention considered for patients in wound healing. Particularly, a type of exercise intervention known as whole-body vibration (WBV) exercise has gained increasing interest. WBV exercise is generated due to the transmission of mechanical vibrations, produced by a vibrating platform, to the body. The aim of this review was to summarize studies in experimental animal models using WBV exercise in wound healing. Searches were performed in EMBASE, PubMed, Scopus and Web of Science including publications on 21 November 2022 using the string "whole body vibration" AND "wound healing" (animal or mice or mouse or rat or rodent). The SYRCLE tool was used to assess the risk of bias (RoB). From 48 studies, five studies met the inclusion criteria. RoB indicated that none of the studies fulfilled all methodological analyzed criteria, resulting in possible biases. The studies were homogeneous, and results suggest beneficial effects of WBV exercise in wound healing, mainly related to enhancing angiogenesis, granulation tissue formation, reducing the blood glucose level and enhancing blood microcirculation, by increasing myofiber growth and rapid re-epithelialization. In conclusion, the various biological effects of the response to the WBV exercise indicate the relevance of this intervention in wound healing in animals. Moreover, considering the translation approach, it is possible to speculate that the beneficial effects of this non-pharmacological therapy might justify clinical trials for wound healing also in humans, after criterion evaluation.

Evidence of Use of Whole-Body Vibration in Individuals with Metabolic Syndrome: A Systematic Review and Meta-Analysis.

(1) Background: Metabolic syndrome (MSy) is defined by a constellation of interconnected physiological, biochemical, clinical, and metabolic factors that directly increase the risk of cardiovascular disease. This systematic review with meta-analysis was conducted to assess the effects of whole-body vibration exercise (WBVE) in metabolic syndrome (MSy) individuals. (2) Methods: An electronic search in Pubmed, Embase, Scopus, Web of Science, ScienceDirect, PEDro, and CINAHL databases in December 2022 was performed. Data regarding the included studies were extracted. The level of evidence, the methodological quality, and the risk of bias of each selected publication were individually evaluated. (3) Results: Eight studies were included in the systematic review and four studies in the meta-analysis, with a mean methodological quality score on the Physiotherapy Evidence Database (PEDro scale) of 5.6, considered "fair" quality. The qualitative results suggested positive effects of the systemic vibration therapy in relevant outcomes, such as quality of life, functionality, pain level, trunk flexibility, cardiovascular responses (blood pressure and heart rate), neuromuscular activation, range of motion of the knees, rating of perceived exertion, and body composition. The quantitative results, with weighted mean differences, standard mean differences, and 95% confidence intervals (CIs), were calculated. Conclusions: WBVE may be an alternative capable of interfering with physical-mainly for flexibility with weighted mean differences (1.70; 95% CI 0.15, 3.25; n = 39)-functional, psychosocial, neuromuscular, emotional parameters, and consequently contribute to improvements in metabolic health and reduce the cardiovascular risk factor in MSy individuals. Nevertheless, further additional studies are required to understand the long-term effects of WBVE on MSy and its complications in a better way. Protocol study registration was as follows: PROSPERO (CRD 42020187319).

Use of surface electromyography to evaluate effects of whole-body vibration exercises on neuromuscular activation and muscle strength in the elderly: a systematic review.

PURPOSE: 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. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.
