Abstract

Introduction: Knee osteoarthritis (KOA) is a joint disease that can cause limitations or loss of physical function. Different nonpharmacological interventions have been recommended for the treatment of KOA. Whole-body vibration (WBV) exercises and auriculotherapy (AT) can be effective interventions for managing KOA. Objective: This study aimed to evaluate the effects of WBV, AT, and the combination of the two techniques on parameters related to functionality in KOA individuals. The hypothesis was that WBV and AT could improve the functional parameters of KOA individuals. Methods: Participants were randomized into four groups (n=108): (i) WBV (GV) using mechanical vibration (MV) with peak-to-peak displacement 2.5, 5.0, and 7.5 mm, frequencies from 5 to 14 Hz and peak acceleration from 0.12g to 2.95g, twice a week, for 5 weeks (n=29); (ii) AT (GA) was performed with mustard seeds at the knee, kidney and Shenmen acupoints on the ear (n=29); (iii) WBV+AT (GAV) (n=23), and; (iv) Control Group procedures (GC) (n=27). Results: As a result, significant improvements were observed in functional parameters of individuals with KOA in the Lysholm evaluation, and in the Timed Up and Go test. WBV and AT would be relevant to be included in primary care, as they are effective, and easy to be performed and have a low cost. Conclusion: The interventions (WBV, AT, and WBV+AT) can lead to physiological responses that can be associated with improvement in clinical-functional parameters in individuals with KOA.
