Using stabilometry, our experimental protocol was designed to demonstrate a quantitative parameter of posture to study forcing of the voice. Analysis of the graphs has shown a perfect correlation between increases in variance of the speed of displacement of the centre of gravity and the increase in the electrical signal from the postural muscles, which is evidence their activation during forcing of the voice . As well as the clinical applications of this protocol, it seems necessary to undertake other studies such cinematographie recording of respiration.
