Abstract/OtherAbstract:
OBJECTIVE: To investigate the effects of squat exercises combined with whole-body vibration on the plasma concentration of inflammatory markers and the functional performance of elderly individuals with knee osteoarthritis. DESIGN: Clinical, prospective, randomized, single-blinded study. SETTING: Exercise Physiology Laboratory. PARTICIPANTS: Thirty-two elderly subjects with knee osteoarthritis were divided into three groups [i.e., squat exercises on a vibratory platform (platform group N= 11), squat exercises without vibration (squat group N= 10) and the control group (N=11)]. INTERVENTIONS: The structured program of squat exercises in the platform and squat groups was conducted three times per week, on alternate days, for 12 weeks. MAIN OUTCOME MEASURES: Plasma sTNFR1 and sTNFR2 were measured using immunoassays (the ELISA method). The Western Ontario and McMaster University Osteoarthritis Index (WOMAC) questionnaire was used to evaluate self-reported physical function, pain and stiffness. The 6-minute walk test, the Berg balance scale, and gait speed were used to evaluate physical function. RESULTS: In the group that performed squat exercises on a vibratory platform, there were significant reductions in the plasma concentrations of the inflammatory markers sTNFR1 and sTNFR2 (p<0.001 and p<0.05, respectively) and self-reported pain (p<0.05) compared with the control group; however, there was an increase in balance (p<0.05) and speed and distance walked (p<0.05 and p<0.001, respectively). In addition, the group that performed squat exercises on a vibratory platform walked faster than the group that only performed squat exercises (p<0.01). CONCLUSION: The results suggest that whole-body vibration training improves self-perception of pain, balance, gait quality and inflammatory markers in elderly subjects with knee osteoarthritis.
