CHANGES IN BODY BALANCE AND FUNCTIONAL PERFORMANCE FOLLOWING WHOLE-BODY VIBRATION TRAINING IN PATIENTS WITH FIBROMYALGIA SYNDROME: A RANDOMIZED CONTROLLED TRIAL

Objective: To determine whether an 8-week exercise programme supplemented with whole-body vibration improves body balance and dynamic strength in women with fibromyalgia. Design: Randomized controlled trial. Patients: Forty-six participants diagnosed with fibromyalgia. Methods: Participants were randomly assigned to: (i) an exercise training group with whole-body vibration (n=15), which performed twice-weekly exercise sessions (aerobic exercise, strengthening and flexibility) combined with 3 whole-body vibration training sessions a week (bilateral squats: 6-9 sets of 30 s with 45-s recovery between sets; and unilateral squat: 4-7 sets of 30 s, 30 Hz-4 mm); (ii) an exercise group (n=15) with the same combined exercise therapy; and (iii) a usual-care control group (n=16). Results: Statistically significant improvements in the Medio-Lateral Stability Index and Medio Lateral Mean Deflection with open eyes were found in the whole-body vibration exercise group compared with the control group. Non-significant effects were found for lower-limb physical function. Conclusion: The results show that a traditional exercise programme, supplemented with whole-body vibration training, improved balance in women with fibromyalgia. This may represent a key factor for falls prevention in this patient group.
