Whole body vibration improves core muscle strength and endurance in ambulant individuals with multiple sclerosis: A randomized clinical trial

The objective of this work was to investigate the effects of whole-body vibration on people with multiple sclerosis (MS). PubMed, CINAHL and Scopus databases were systematically searched for studies on the use of whole-body vibration (WBV) exercise in people with MS. These searches were supplemented with material identified in the references and in the authors’ personal files. A qualitative analysis was performed to summarize the findings. Five studies with a total of seventy-one subjects were identified. All of these studies had small numbers of subjects (3–25), and two of the studies had no control groups. Some investigations have shown significant improvements of the muscle strength, of the functional mobility, and of the timed get up and go test in patients with MS. The number of publications found in the databanks searched is small, and in general, they have limitations in the design of protocols with a weakness to the interpretation of the findings. However, the analysis of the findings in these studies permits to conclude that some papers indicate that WBV exercises could benefit patients with MS. In addition, we suggest further larger scale investigations with controlled parameters and well-designed protocols into the effects of WBV exercises in people with MS.

Body Vibration

Multiple sclerosis (MS) is a type of degenerative syndrome that causes impaired physical function, decreased walking, imbalance, spasticity, sensory impairment, muscle weakness, fatigue, and demyelination of the central nervous system. The purpose of this review was to critically examine available studies on the efficacy of whole-body vibration (WBV) in patients with MS during rehabilitation training to increase strength, balance, and functional mobility. An organized literature search was performed on databases from various sources, including PubMed, MEDLINE, CINAHL, and EMBASE, to identify relevant randomized clinical trials (RCTs). Eight studies were finally selected based on exclusion and inclusion criteria. Attempts were made to identify factors affecting the improvement in muscle strength, balance, and functional mobility in MS patients as a result of WBV. A meta-analysis was performed if two or more studies measured the same outcome of interest. The meta-analysis found that the WBV intervention showed significant improvement over control groups in Body Balance Score (BBS) (MD = [Formula: see text]2.86, 95%CI = [Formula: see text]5.29 [Formula: see text] 0.43; [Formula: see text], [Formula: see text], heterogeneity ([Formula: see text]%). In addition, walking endurance (6MWT) favored control groups over WBV intervention (MD [Formula: see text], 95%CI [Formula: see text][Formula: see text] 99.41; [Formula: see text] = 2.97, [Formula: see text]). Timed-Up-and-Go Test (TUG) and Expanded Disability Status Scale (EDSS) ([Formula: see text]) had no significant effect on WBV. Restoration of balance and functional mobility appeared to respond better to WBV with additional exercise protocols compared to WBV alone. Although there is evidence of an overall effect of WBV on strength and some measures of balance and mobility, its impact remains inconclusive. Therefore, more robust RCTs examining exposure to WBV on balance and functional mobility in patients with MS are warranted.
