Research study |
| Subjects |
6 males, 2 females;
ages 12-29; |
| Diagnoses |
Severe TBI with traumatic midbrain syndrome |
Speech
Condition |
Traumatic mutism |
| Purpose |
To document the recovery of phonation
following traumatic mutism and to identify patterns in the recovery of
normal laryngeal function.
To establish characteristics of dysphonia
following traumatic mutism. |
| Methods |
Phoniatric exam-Evaluation of sensory
and motor functions of the laryngeal and pharyngeal musculature, laryngoscopic
exam, and magnifying laryngoscopic exam to exclude lesions
Aphasia exam-Short form of the
Token Test
Phonetic exam-Every 3 weeks the
following were assessed: articulators, articulatory testing with words,
phonatory skills, pitch range, and glottal onset
Two phoneticians rated the recordings
to assess changes in phonation and pathological vocal behavior. |
| Results |
Onset of voiced phonation was high in
pitch then decreased.
The subject's normal pitch returned before
normal loudness.
Volitional nonspeech laryngeal function
returned with normal voice functions.
Duration of expiration extended to the
normal length.
There was a reduction or disappearance
of breathiness.
Strained voice was present with raising
and lowering pitch which disappeared in some and in others it remained. |
