Review article (meta-analysis)Therapeutic Effects of Whole-Body Vibration Training in Knee Osteoarthritis: A Systematic Review and Meta-Analysis
Section snippets
Data sources
The search for published studies was conducted using PubMed, CINAHL, Embase, Scopus, Physiotherapy Evidence Database (PEDro), and Science Citation Index using a combination of the keywords whole body vibration, vibration therapy, and vibratory exercise with osteoarthritis knee and the Medical Subject Headings osteoarthritis, knee combined with whole body vibration or vibration. The bibliographic search was restricted to randomized controlled trials (RCTs) published in the English language prior
Identified studies
The initial search resulted in 83 research studies. A total of 65 studies that appeared in >1 database or did not meet predetermined inclusion criteria were excluded. A total of 18 studies were assessed for eligibility. Thirteen studies were eliminated because they did not match the inclusion criteria or were not available in full text (fig 1).5, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 The final selection, made by consensus, resulted in the inclusion of 5 studies in the quality
Discussion
The present review evaluated 5 RCTs including a total of 165 participants to examine evidence regarding the therapeutic effect of WBV in the management of knee OA. Among the 5 studies evaluated using the PEDro Scale,14 4 were considered of high methodologic quality. Of the 5 included studies, 3 studies would be regarded as high risk of bias because they failed to fulfill the required criteria.7, 8, 10 Our evaluation showed that more than half of the studies performed adequate random sequence
Conclusions
WBV has demonstrated limited but beneficial therapeutic effects in individuals with knee OA. WBV training reduces pain and improves function in individuals with knee OA. In the present review there is a variation in the vibration protocol, training dose, and reported results. Therefore, more robust, well-designed studies are required for conclusive evidence of the beneficial therapeutic effects of WBV training in individuals with knee OA.
