| Abstract | Introduction: Electromyographic activity of lower limb muscles decreases in knee osteoarthritis. Whole body vibration is a suitable intervention in strengthening muscles, whose effect on the electromyographic activity of lower limb muscles during functional activity has not been properly investigated. The purpose of this study is to investigate the effects of whole-body vibration on the electromyography of the lower limb muscles of people with knee osteoarthritis during functional activity. Materials and Methods: This clinical trial study was conducted on 30 people with knee osteoarthritis who were included in the study based on the inclusion and exclusion criteria. The participants were randomly divided into intervention and control groups (15 people in each group). Both groups were subjected to routine physiotherapy treatment, and the intervention group was subjected to whole-body vibration with a frequency of 30 Hz and an amplitude of 2 mm for 4 weeks and 3 times a week. Before and after the intervention, the EMG of the vastus medialis, vastus lateralis, biceps femoris, and semitendinosus muscles were recorded using surface electromyography while walking. Results: The results of this study showed that the RMS activity of the lower limb muscles increased significantly in both the intervention and control groups, and no statistically significant difference was observed between the two groups. Conclusion: Whole body vibration has no significant effect on electromyography of lower limb muscles of people with knee osteoarthritis. Another study with a larger sample size is recommended. | en |
