Background: The application of mechanical multifocal vibration (MFV) at targeted frequencies and short duration produce positive effects on bone structure, muscles and joints regulating neuromuscular response. Objective: The purpose of this study was to investigate the effects of the global proprioceptive resonance (GPR) by MFV on muscle performance and body balance in healthy subjects. Materials and Methods: Sixty volunteers (26 males and 24 females, aged 19-25 years) underwent, in a randomized order, both the electromyography- electrognatography (EMG-EGN) and stabilometry before the GPR and immediately after it. GPR was the ergonomic structure used in this protocol: it gives a psyco-physical release thanks to multifocal vibrations. Results: The effects of GPR on the surface EMG of masseters and anterior temporalis muscles did not induce any statistically significant change, except to masseters muscles (p<0.05). The results showed a significant improvement in the neuromuscular activity. Muscular activity meanly decreased, while the Freeway Space increased in 53% of cases: this was the evidence of a muscular release after GPR. From a postural point of view, there was an improvement in the loads distribution and in the position of the barycenter according to the ideal axis.There were effects in body balance tests, too (p<0.05). Conclusions: In this preliminary study it was concluded that the GPR induced changes both in neuromuscular and in postural tests. Further and future studies should focus on evaluating the effects on orthodontic and temporomandibular disease patients, as well as the long term effects.
