Vibration training is a relatively new exercise intervention. This study investigated the effects of vibration exercise on strength (force-producing capacity) and power in older adults who are healthy.
Thirty participants (mean age=73.7 years, SD=4.6) were randomly assigned to a vibration exercise training (VIB) group or an exercise without vibration training (EX) group. The interventions consisted of 3 sessions per week for 8 weeks. Outcome measures included isokinetic flexor and extensor strength and power of the hip, knee, and ankle.
The VIB group significantly improved ankle plantar flexor strength and power compared with the EX group. However, there were no significant differences between the VIB and EX groups for knee flexor or extensor strength.
Vibration training contributed to an increase in plantar flexor strength and power. However, the strength gains for the knee and hip flexors and extensors for the VIB group and the EX group were comparable. Future vibration protocols should explore different body positions to target muscles higher up on the leg.

    • "Nonpharmacological therapies include physical therapies such as yoga, tai chi, walking, and whole-body vibration (WBV) [9]. WBV is a physical therapy that was shown to improve muscle strength [10], body balance [11], gait mobility [12], cardiorespiratory fitness [13], bone-density [14], and pain [15] in healthy and various clinical populations. WBV can be delivered by two types of exercise platform. "

    ABSTRACT: Objective. To review the literature on the effects of whole-body vibration therapy in patients with fibromyalgia. Design. Systematic literature review. Patients. Patients with fibromyalgia. Methods. An electronic search of the literature in four medical databases was performed to identify studies on whole-body vibration therapy that were published up to the 15th of January 2015. Results. Eight articles satisfied the inclusion and exclusion criteria and were analysed. According to the Dutch CBO guidelines, all selected trials had a B level of evidence. The main outcomes that were measured were balance, fatigue, disability index, health-related quality of life, and pain. Whole-body vibration appeared to improve the outcomes, especially balance and disability index. Conclusion. Whole-body vibration could be an adequate treatment for fibromyalgia as a main therapy or added to a physical exercise programme as it could improve balance, disability index, health-related quality of life, fatigue, and pain. However, this conclusion must be treated with caution because the paucity of trials and the marked differences between existing trials in terms of protocol, intervention, and measurement tools hampered the comparison of the trials.

    • "Lam et al.13) reported that whole body vibration (WBV) exercise improves elderly individuals’ balance and gait and is an effective intervention for fall prevention. Other researchers have reported that WBV exercise is effective in improving bone strength, muscle strength of the lower extremities, and functional mobility14, 15). In addition, Pollock et al.16) conducted an 8-week intervention of WBV exercise in participants over 80 years of age and found that balance, gait, and fall efficacy improved significantly in this group compared with a control group.

    ABSTRACT: [Purpose] The purpose of the present study was to investigate the effects of whole body vibration exercise in the horizontal direction on balance and fear of falling in the elderly. [Methods] This study was a case series of 17 elderly individuals. Participants performed whole body vibration exercise in the horizontal direction using a whole body vibration device for 15 minutes a day, 3 times a week, for 6 weeks. At baseline and after the 6-week intervention, balance was measured using the Berg Balance Scale and Timed Up and Go test, and fear of falling was assessed using the Falls Efficacy Scale. [Results] After the intervention, significant improvements from baseline values in the Berg Balance Scale, Timed Up and Go test, and Falls Efficacy Scale were observed in the study participants. [Conclusion] Elderly individuals who performed whole body vibration exercise in the horizontal direction showed significant improvements in balance and fear of falling. However, the observed benefits of whole body vibration exercise in the horizontal direction need to be confirmed by additional studies.

    • "In consequence some authors have demonstrated an improvement of the ankle plantar flexor strength and power [23] and the enhancement of the stability [24]. In keeping with the WBV working mechanism suggested and the findings reported in the literature [23] [24], it has already been tested in some patients disorders with neurological disorders [7] [8] [17] [25]. As no previous systematic reviews of the effects of WBV exercise on people with MS have been published, the purpose of this study was to systematically review the published research concerning the use of WBV in people with MS.

    ABSTRACT: 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.
