OBJECTIVES. The purpose of this study was to investigate the effects of an ergonomic structure using multi focal vibrations (MFV) on muscle performance and body balance in healthy subjects. MATERIALS AND METHODS. 30 volunteers (16 males and 14 females, aged 19-25 years) underwent, in a randomized order, both electromyography (EMG) and stabilometry before being subjected to global proprioceptive MFV resonance and immediately after it. RESULTS. The effects of MFV on the surface EMG of masseter and anterior temporalis muscles induced statistically significant changes in masseter muscles (p <0.05). Similar effects were recorded by postural and stabilometric tests (p <0.05). CONCLUSIONS. MFV induced changes in both neuromuscular and postural tests.
