[Determination of kinesiographic parameters in phonation].
We have registered mandibular movements produced during the reading of a text in spanish with a Sirognathograph in a random sample of 71 subjects, aged between 24 and 35, on the three planes of space. The obtained curves have allowed to measure 7 variables in order to define the characteristics of mandibular movements during speech. The results demonstrate that determinant planes for this purpose are sagittal and frontal.
