Abstract: Objective: To assess the effects of whole body vibration for pain, stiffness and physical functions in patients with knee osteoarthritis. Data sources: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Physiotherapy Evidence Database (PEDro) and EMBASE (up to October 2014) to identify relevant randomized controlled trials. The outcome measures were pain, stiffness and physical functions. Review methods: Two investigators identified eligible studies and extracted data independently. The PEDro score was used to evaluate the methodological quality of the selected studies. Standard mean differences (SMDs) and 95% confidence intervals (CIs) were calculated, and heterogeneity was assessed using the I2 test. Results: A total of five randomized controlled trials involving 170 patients with knee osteoarthritis met the inclusion criteria. Only four studies involving 144 patients were deemed to be good quality trials (PEDro score = 6-7). Meta-analysis revealed that whole body vibration has a signicant treatment effect in Western Ontario and McMaster Universities index physical function score (SMD = '0.72 points, 95% CI = '1.14 to '0.30, P = 0.0008), 12 weeks whole body vibration improved the 6-minute walk test (SMD 1.15 m, 95% CI 0.50 to 1.80, P = 0.0006) and balance (SMD = '0.78 points, 95% CI '1.40 to '0.16, P = 0.01). Whole body vibration was not associated with a signicant reduction in Western Ontario and McMaster Universities index pain and stiffness score. Conclusion: Eight-week and 12-week whole body vibration is beneficial for improving physical functions in patients with knee osteoarthritis and could be included in rehabilitation programs.
