[Multi-dimensional study of the voice in the teaching professionals of La Rioja].

The vocal pathology is very frequent among the teaching professionals. We have selected 140 teachers, 70 normals, and 70 with dysphonia. To all of them we have realised a complete voice exploration: aerodyinamic tests, tone and extension of the voice, perceptual evaluation of the voice with the GRBAS scale and also a videolaringostroboscopy to diagnose the teachers. Among the dysphonic teachers there is a poor neumophonologic coordination, a major use or an inadequate use of the respiratory and/or laryngeal musculature. The dysphonic teachers present a more pathological voice in the GRBAS scale than the normal teachers.
