Effect of whole body vibration exercise on muscle strength and proprioception in females with knee osteoarthritis

Abstract Background Knee osteoarthritis (KOA) is among the most common osteoarthritis diseases that affect adults older than 65 years old. Impaired neuromuscular function contributes to the development and/or progression of KOA. As a new modality in strength training, whole-body vibration (WBV) training is considered in the management of KOA. However, the inconsistent results of previous studies dampened the enthusiasm for the clinical application of WBV.Methods Eligible participants with KOA were randomly allocated to WBV, strength training (ST) and health education (HE) groups. Finally, 57 participants completed the intervention and measurements. The participants in each group were encouraged to perform the WBV training, similar strength training or health education program. These supervised interventions were performed three times per week for 8 weeks. Physical function was assessed with Timed Up and Go (TUG) and 6-min Walk Distance tests. Neuromuscular function was measured with isokinetic muscle strength and proprioception. Results All variables of physical function and neuromuscular function failed to change significantly among three groups. However, compared with the baseline, the time of TUG and isokinetic muscle strength improved significantly only in WBV group. Conclusion WBV training has been recommended for strength training in elderly people and patients with musculoskeletal diseases. The 8-week WBV training under the protocol of our study was not superior to ST and HE. Hence, more clinical studies are required in the future to develop an optimal training protocol.

Objectives. To assess the effects of WBV exercise on patients with KOA.Methods. Eight databases including Pubmed, EMBASE, Cochrane Library, CINAHL, Web of Science, the Physiotherapy Evidence Database, CNKI, and Wanfang were searched up to November 2014. Randomized controlled trials (RCTs) of WBV for KOA were eligible. The outcomes were pain intensity, functional performances, self-reported status, adverse events, and muscle strength. A meta-analysis was conducted.Results. Five trials with 168 participants provided data for the meta-analysis. No significant difference was shown in pain intensity and self-reported status between WBV and other forms of exercise. Improvement in functional performance (evaluated by BBS; WMD, 2.96; 95% CI, 1.29 to 4.62;P=0.0005) was greater in WBV group, but the other parameters of functional performance (including 6MWT and TGUG) revealed no statistically significant difference. Adverse events were only reported in one trial and no significant difference was discovered in muscle strength. The overall quality of evidence was very low.Conclusion.Currently there is only limited evidence that suggested that WBV is effective in the treatment of KOA. Large, well-designed RCTs with better designs are needed.Erratum to “Whole-Body Vibration Exercise for Knee Osteoarthritis: A Systematic Review and Meta-Analysis”
