Pediatric Phonatory Disorders 1 Evaluation Procedures • No standardized test is available • Diagnostic results form (5-2) –respiration –phonation –resonance –high risk factors 2 Eliciting Samples of Respiratory Behavior • Length of inhalation- straw with tissue paper • Depth of inhalation- Birthday cake candles • Depth & length of inhalation- blowing through a straw in a glass of water • Number of syllables in an exhalation-alphabet in one breath • Replenishing breaths- cars need to stop for gas, trains stop at stations, older children mark reading passage 3 Eliciting Samples of Phonatory Behavior • Count from 1-40 softly than loudly • Sustain the vowel /a/ for as long as they can (about 10 sec.)- “keep going until my pencil stops” • Produce /s/ and /z/ for as long as they can- “sammy snake goes /s/”, “keep going until he gets into his house”, “the motorcycle goes /z/” • Onset of phonation affected by loudness level- “Uncle Eddie eats eggs” soft & loud (hard glottal attacks) 4 Eliciting Samples of Phonatory Behavior • Excessive effort- ask child to swallow than phonate vowel (same muscles used may be excessive tension) • Excessive effort due to edema or lesion- best during loud speech or stressed syllable, (repeat multisyllabic words, note aphonia on unstressed syllable- Mississippi, Alabama) • Vary loudness- soft to loud, police car going farther away “whoo..” 5 Eliciting Samples of Phonatory Behavior • Vary pitch- sing “Happy Birthday” • Understands loud vs. soft- big puppet (loud voice), small puppet (soft voice), repeat sound, ask child to identify puppet • Aphonia or adduction problem- loud and soft description of picture 6 Eliciting Samples of Resonance Behaviors • Hypernasality1) Say [an, am] vigorously- velum up for /a/ and down for /m,n/, symmetrical movement 2) Sustain nonasal sounds, occlude nostrils (no difference with adequate v-p closure) 3) Sounds requiring oral breath pressure-“Chip bits of ice”, “Kitty has fleas”, “Freeze the peas” -V-P closure problems will show 7 Eliciting Samples of Resonance Behaviors • Hyponasality1) Mouth breather- indicates nasal obstruction 2) Produce nasals with appropriate nasal resonance and vibration in nasal area? 3) Nasal sentences- “My mommy make me mad”, “My nose never runs”, do you here proper resonance 4) Inability to hum- nasal obstruction 8 Eliciting Samples of Interpersonal Behavior • Conversation with one or more children- “Some people say that school should be all summer” (Turn taking, amount of talking, interruptions) • Notice feedback- ask children to tell the true meaning of sentences spoken different ways: – “I like school” (flat intonation or questioning inflection) – “He’s a good person” (negative facial expression, questioning intonation) 9 Eliciting Samples of Interpersonal Behavior • Interpret vocal patterns used by clinician pretending to be different people (young child, elderly person, police officer etc.) • Sample story & have child tell you why things happened, retell story (analyze child’s needs and interests of others) 10 Eliciting Samples of Voice During Conversational Speech • Describe your best friend. • Tell me four things you did in school today. • Describe the plan of your house. Start at the front door. • Tell me about a movie you saw recently. • Say something you like about yourself. • What are you looking forward to this week. 11 Professional Voice 12 Speech-Language Pathologist’s Role • When compared with voice disorders in a nonperformer, will the SLP find that there is anything significantly different about evaluating and remediating voice problems in the performer? 13 Special Considerations • Range of vocal activities extends beyond functional parameters • Signaled by subtle changes in quality, pitch range, loudness extreme etc. • Knowledge of music: styles and vocal characteristics called for by music school, composer or dramatist • Understanding of physical demands 14 Goals of Therapy • Less latitude with respect to desired outcome • Become familiar with the technical rudiments of these disciplines, terminology and imagery • Stage direction, set and costume design • Special environmental contributors to professional voice • Psychosocial pressures: competition, pressure to succeed, judgment 15 Interdisciplinary Voice Team • • • • • • • Speech-Language PathologistSinging specialist/ Vocal TeacherVoice Scientist or Singing CoachSpeech/Drama CoachPsychologistHypnotherapistPhysicians- 16 Evaluation • Expectations of normal are heightened • Case history – description of circumstances – laryngologist & SLP collect info – activities in daily professional life – daily vocal usage patterns – smoking, passive smoking, alcohol – type of music (rock, jazz, classical, gospel, night club, jazz/blues) – professional career goals 17 Evaluation- Examination • Objective Voice Measures 1. Audio recording (protocol App. IV) 2. Sample of sustained spoken & sung vowels, conversational speech and reading 3. Acoustic parameters: Fo, jitter, shimmer, harmonics/noise ratio, percent voicing, physiological and musical frequency range and maximum phonation or expiration time 4. Respiration measured by PFT 18 Subjective Evaluation • Respiration 1. Observed in conversational speech -pattern of breath support -posture -phrasing -respiration 19 Subjective Evaluation • Phonation 1. Voice quality 2. Harsh glottal attacks are counted during reading 3. Measures of respiratory & phonatory efficiency are obtained: -MPT for: /a/, /I/, /u/, /s/, /z/ 4. s/z ratio 20 Subjective Evaluation • Resonance 1. Presence of hypo- or hypernasal speech 2. Functional or regional resonance deviations- reading 3. Tongue position observed during sustained /a/ 4. Posterior tongue tension- responsible for pharyngeal resonance quality 21 Subjective Evaluation • Articulation 1. General judgment on precision 2. Smooth transition of articulators 3. “hyperfunctional” articulation or tension sites • Prosody 1. Rhythm, fluency, timing, rate, pauses and intonation are generally assessed 2. Laryngeal strap tension- demonstrate faulty flow & blending of words 22 Subjective Evaluation • Sites of muscular tension 1. poor respiratory control 2. tension sites? • Oral/Facial 1. screening to rule out structure, symmetry, strength, range of motion or coordination difficulty • Singing 1. Unless trained not qualified to evaluate singing 2. observation in consistency of techniques from singing to speaking 3. checklist 23 Therapy • Designed to have patient feel and sound better • Initial focus is on speaking technique • Facilitate “learning to speak by feel” • Identify the factors which have created voce problem • Education- vocal hygiene, anatomy 24 Establishing good vocal hygiene • Throat clearing – dry swallow – small sips of water – “silent cough” – pant lightly then swallow – hum lightly – laugh lightly & swallow – talk through the mucous – vocalize lightly on five-note scales in a comfortable range on /a/ or slide up an octave softly on /a/ 25 Establishing good vocal hygiene • Whispering – avoid – anterior 2/3 approximate – forced most harmful • Grunting/ Noisy Vocalizations – exhale slowly on the exertion phase of exercise – adduct the vocal folds gently, prior to initiating each exercise • Yelling/ Screaming or loud talking – use whistle or bell – engage the help from others for monitoring 26 Establishing good vocal hygiene • Noisy environments – – – – facing the listener gently overarticulate rather than increase loudness slowing speaking rate speak in normal pitch • Excessive talking – schedule vocal “naps”. 20 minutes of silence 2-3 times daily – digital watch alarms to signal reminder to check vocal behavior – limit time on telephone 27 Establishing good vocal hygiene • Caffeine consumption – avoid caffeinated beverages before heavy vocal use – glass of water for every cup of coffee • Systematic dryness – – – – “sing wet- pee pale” drink water every time you eat keep water on hand try bottled water with a twist • Environmental dryness – superhydrate prior to air travel – use humidifier – moist environment 28 Relaxation • Yawn-sigh • Improving sensory awareness of soft palate, muscles of pharynx, and tongue • Create open, relaxed pharynx • Establish a high soft palate position, useful for oral resonance improvement 29 Range of Motion • • • • • • • • head forward and back head side to side looking over each shoulder shoulder rolls shoulder shrugs jaw relaxation tongue stretch chewing 30 Self-Massage • Facial massage • Posterior neck and shoulder massage • Body posture & head/neck alignment 31 Breath Control & Support • Description of breathing • Count pacing for during breathing • Differences in support for speaking and singing • Warm-up and cool down routines • Speech breathing for non-speech tasks • Nonspeech to speech tasks • Support for ongoing speech 32 Easy Onset Exercises • • • • • • • • Negative practice Single words Minimal Pairs Long versus short vowels delay approach Downward slide “Key word” approach Blending 33 Tonal Focus/ Vocal Placement in Speech • 2 axis: up/down & front/back • Difference between pitch & placement • Consonants first (alveolar ridge or anterior) • Contrast back and front words • “buzzing” in front of mouth 34 Loudness vs. Projection • Projection- maximizing listener intelligibility with minimal speaking effort • Perception of increased loudness • Single words (increasing breath support) • Using speech sounds in phrasing • Combination • Prosody 35 Warm-up and Cool-Down • Consistent practice each morning prepares the vocal mechanism • Outline of the daily practice exercises • Muscular stretch & range of motion • Vocalize scales 36 • Nonspeech tasks
