Chapter 2: Assessment Flashcards
Professionals concerned with voice
Medical Team: physician, neurologist, radiologist
School Team: teacher, school psychologist, school nurse
Professional Voice Team: Otolaryngologist, singing teacher, nurse
Methods of Approaching Voice Assessment
- Tests and Scales
Validity, reliability, standardization, norm-ref, listener’s perceptions, auditory perception scales, eval of voice samples - Research that Informs Clinical Assessment Methods
perceptual judgments of pitch/roughness, acoustic measures (amplitude, frequency, glottal noise measures), calculating fundamental frequency, acoustic measures and auditory-perceptual dimensions. No international guidelines - Instrumental Analysis of Voice Production
Electromyographic assessment, aerodynamic assessment, photographs, videoendoscopy, laryngeal mirror exam - Instrumental Analysis of Velopharyngeal Funciton
- Indirect methods of measuring correlates of vocal fold vibratory behavior
EGG, PGG, Transillumination, Inverse filtered signal, acoustic measures - Behavioral Analysis of Production
Hearing screening, position and posture, oral-periph exam, elicitation of reflexes, resonance and swallowing patterns, respiration, artic, prolonged vowels - Analysis of Product
Frequency, amplitude, aperiodicity, coordination and timing - Analysis of the Producer
Medical history, psychological history - Analysis of Processor
client description, self-perception scales, others’ perceptions
Appraisal History/background
leading questions use reflecting statements observe nonverbal behavior listen to audible characteristics note consistency and variability of symptoms
Selecting Diagnostic Strategies
Testing hypothesis during interview
Confirmation of clinical impressions
Manipulation of key variables
Eval of nose and nasopharynx
signs of allergies, infection clefts enlarged adenoids palatal tremor velopharyngeal closure VPI
Eval of oropharynx and hypopharynx
mass or lesion infection neurologic disease tremor tongue weakness/incoordination
Eval of larynx with scope above epiglottis
reflux
tremor
motion of folds during breathing
vocal fold adduction which occurs irregularly
observation of folds during sustained vowels, various pitches, whistling, repeated vowels
MTD (muscle tension dysphonia)
Eval of larynx with scope above folds
inspect folds, epiglottis
detect masses, scarring
observe sustained vowel
request sofy, high pitch to reveal lesions, weakness
Eval of singing
focal tremor (folds or arytenoids) general tremor
Eval of spasmodic dysphonia
periodic breaks in voicing
normal phonation during some specific tasks
Objective means of voice assessment
Acoustic analaysis Electroglottography Stability of measures Instrumental analysis profile Interpretation of measures
