项目摘要
It is generally believed that "vocal hyperfunction" is an underlying
component in a majority of voice disorders, but there is a paucity of hard
data concerning: l) specific physiologic and acoustic manifestations of
vocal hyperfunction, and 2) the actual role of hyperfunction in the
development and maintenance of various voice disorders. Thus, the primary
goals of this project are to develop and use measures to: l) provide
objective descriptions of conditions referred to as "vocal hyperfunction",
and 2) add to existing knowledge concerning "normal" voice production in a
way which will aid in interpreting data on hyperfunctional voice
production. These goals will be accomplished through the use of a unique
combination of non-invasively obtained indirect measures which should
delineate relationships between underlying physiological mechanisms and
acoustic characteristics of voice production. These measures will
include: parameters derived from inverse-filtered approximations of the
glottal air flow waveform, estimates of glottal resistance and vocal
efficiency, measures of vocal intensity and fundamental frequency, and
electroglottographic estimates of vocal-fold contact patterns. These
measures will be related to information gathered from medical examination
of the larynx and auditorily-based judgements of voice quality. Data will
be obtained from five groups of subjects (2 non-pathologic and 3
pathologic) designed so that the nature of hyperfunction can be studied in
dysphonias that exist: l) in the absence of organic pathology, and 2) in
benign vocal pathology believed to be the result of abuse/misues of the
voice.
The experimental design is motivated by a set of interrelated hypotheses
which form a descriptive "model" of vocal hyperfunction. Data analysis and
interpretation will be related to this model. The results are expected to
provide new information about hyperfunctionally-related voice disorders
which is based on objective measures. Such information should help in the
differential diagnosis and in understanding the role of hyperfunction in
the development and maintenance of various voice disorders. Measures which
turn out to be the mose relevant for describing vocal hyperfunction should
also have future clinical utility as diagnostic tools and as means for
studying therapeutic efficacy.
