Quality of life (QoL) is one of the most important health outcome concepts expressed subjectively. Chronic pain (CP) is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Taking into account the poor QoL and the CP already described in metabolic syndrome (MSy) individuals, this study aimed to evaluate the effects of WBVE on these parameters in this population. Thirty-three MSy patients were divided in subgroup A (WBVeG, n=17, 15 females/02 males, 61.1±8.4 yrs) and B (control group, CG, n=16, 14 females/02 males, 58.2±9.1 yrs). The subgroup A performed 10 sessions (twice per week) of WBVE (18 minutes/each session, with a frequency from 5 up to 14 Hz and a peak to peak displacement (PPD) of 2.5, 5.0 and 7.5 mm) on the side alternating vibrating platform (VP) (Novaplate, Fitness Evolution ®, São Paulo, Brazil). The subgroup B did the same protocol, but the VP was turned off. The individuals answered the World Health Organization Quality of Life bref (WHOQoL-bref) questionnaire, before the first and after the 10 session. The CPL was measured by a numeric rating scale (NRS) (0-10), before and at the end of each session. Significant improvements were found in physical health (=0.05) and psychological health (=0.04) domains of WHOQoL-bref in WBVeG. A significant acute reduction of the CPL was found in the WBVeG after the protocol, considering the first session (FS) and at the last session (LS). WBVE marginally improved physical health and psychological health and decrease the CPL in acute interventions.
