The extrinsic and intrinsic laryngeal
muscles are exquisitely sensitive to emotional
stress. Their hypercontraction is the common
denominator behind the dysphonia and aphonia in
virtually all psychogenic voice disorders.
The
yawn-sigh as a voice therapy technique
has had increased usage in recent years,
particularly with voice problems related to
vocal hyperfunction. The technique appears to be
especially effective in counteracting the
tension symptoms of elevated larynx and
constricied vocal tract that so often
characterize vocal hyperfunction that is
defined as the involvement of too much muscle
force and physical effort in the systems of
respiration, phonation, and resonance. Natural
functions to overcome vocal constriction are the
sigh and the yawn, both useful in overcoming,
the upward pull of the larynx. These vocal
techniques are designed to open up the vocal
tract, permitting an easier phonation with a
minimum of muscular effort.
Le
bâillement - sifflement comme
thérapeutique des
dysphonies
La musculature extrinsèque et
intrinsèque de larynx est
particulièrement sensible au stress
émotionnel. Son hypercontraction est le
dénominateur commun de toutes les formes
de dysphonies et aphonies fonctionnelles ou
psychogènes.
Le
bâillement - sifflement est une
technique qui s'impose peu à peu depuis
quelques années, en particulier comme
thérapeutique des surmenages vocaux.
Cette technique est particulièrement
efficace pour combattre
l'élévation excessive du larynx et
la constriction de la glotte qui
caractérisent le surmenage vocal.
Celui-ci correspond à un effort
musculaire excessif des systèmes
respiratoires, vocaux, et de résonance
qui tend à élever le larynx. Cette
technique cherche à ouvrir la glotte et
à repositionner le larynx au plus bas de
sa course afin de réduire l'effort
musculaire au minima.
