9/12/2019 1 Evidence Based Interventions for Beginning Stuttering MARYBETH ALLEN, M.A., CCC-SLP, BCS-F (RET) MAINE SPEECH LANGUAGE HEARING ASSOCIATION NOVEMBER 6, 2019 1 2 SPEECH FLUENCY Fluent Speech •Effortless flowing speech Disfluent Speech •Breaks in the flow of speech 2 Criteria for “stuttering speech behavior” as 3 a “disorder” Yairi & Seery (2015) Transcribe at least 2 contexts conversational speech sample At least 500 - 600 syllables 3-4 % SLDs in sample and Calculate frequency stuttered syllables. 2+ rep per unit is lowest level for stuttering. (SLDs= PWR, MWR, DysRPh, Blocks) Do not count # reps as individual stutters Any number of repetitions, prolongations, word breaks, tense pauses, or phonatory blocks can be associated with ONE stuttered word or syllables Categorize interjections/revisions if used as starters, avoiders, when connected to word production as avoidances and/or stutters. Use in description of severity and characteristics. Calculate average %age of both SLDs and NLDs. For severity, make observations of frequency, # reps, clusters, types of stutters, other secondary and non-verbal behaviors. 3 1 9/12/2019 4 Stuttered speech is disfluent speech but…not all disfluent speech is stuttering Least Normal-Like Disfluency (NLDs) Stuttering-Like Disfluency (SLDs) Hesitations & silent pauses Part-word/syllable repetitions Interjections: word & non- Sound repetitions word fillers Prolongations Whole word repetitions Blocks Phrase repetitions *Greater than average Revisions Tension Duration Effort & Struggle Most Gregory & Hill, 1993 ; Tumanova et al., 2014; Yairi & Seery, 2015; Yaruss & Reeves (2013) 4 5 Childhood Onset Fluency Disorder F80.81 Other term often seen is “Persistent Developmental Stuttering” Fluency Disorder in conditions classified elsewhere R47.82 Types of Parkinsons Stuttering TBI Fluency Disorder (stuttering) following ICD-10 CM cerebral vascular disease I 69 codes Stroke Adult Onset Fluency Disorder F98.5 A very small %age of adult onset appears psychogenic in origin 5 6 From now on… Childhood Onset Stuttering 6 2 9/12/2019 Childhood Onset Stuttering – 7 One simple definition Guitar 2014 Stuttering is characterized by an abnormally high frequency and/or duration of stuttering like disfluencies ( > 2% SLDs, > 2 repetitions per unit) PWS (people who stutter) react to their stutter with effort, force, and sometimes extra movements PWS react to their stutter with emotions such as frustration, surprise, embarrassment and fear. 7 Other Reported and Observed 8 Characteristics Guitar (2014), Manning (2010), Yairi & Ambrose (2013), Yaruss & Reardon-Reeves (2017), Vanryckeghema, M., (2004) Onset most often between ages 2 – 4, when complex speech begins to emerge Approx. 95% of children who stutter, do so before the age of 5 years. Incidence: 5% of all children 70-80% of children DX with early stuttering will recover with or without TX The other 25%?...Persistent, Chronic Stuttering 1% Prevalence in population Beginning stuttering often “comes and goes”, until it is there to stay Often results in delayed referrals Persistent stuttering is a chronic disorder Although much disinformation on “cures” is available to any who are looking for it 8 Other Reported and Observed Characteristics con’t 9 Bolyle (2015), Guitar (2014), Manning (2010), Yairi & Ambrose (2013), Yaruss & Reardon-Reeves (2017), Vanryckeghema, M., (2004 Several “conditions” in which stutterers ‘never’ stutter Choral reading, singing, automatic speech, “acting”, etc. Some theories related to a secondary motor trac for this kind of speech Consistently Inconsistent Contextual variables are extremely important Linguistic, Social, emotional, cognitive, physical Severity of disorder is NOT dependent upon observable stuttering Covert Stuttering – exists on a continuum Need to assess the “impact” of the disorder or you are not assessing the whole disorder.

Kraft and Yairi (2011) , Drayna & Kang (2011), Manning, Genetic (2010), Guitar & Conture (2013) predisposition “There is extensive evidence for genetic factors found through studies of affected families and twins, although most of the “factors” have yet to be found….Of the specific genes that have been found, however, it’s still not clear how they cause the disorder ” (Drayna, 2015) 15 5 9/12/2019 16 Using PET and fMRI, differences found in: blood flow and activations in cerebral speech centers sub cortical structures. hemispheric differences between stutterers and non stutterers Neurophysiological differences Differences in various measures of motor timing and integrating complex motor - Adults tasks Structural and anatomical differences. cortical folding and white matter connectivity DeNil (2004), DeNil et al (2007) Guitar (2014) Ingham et al.(2004) Manning (2010) 16 . 17 Reduced volumes of gray matter in left hemispheres.

It is the converging of several factors that the clinician must look for” 24 8 9/12/2019 The what, when, where & how 25 of therapy flows from where the client is in the cycle Beginning Stutterers Mostly a “speech behavior disorder” Isn’t it about Mostly easy repetitions and prolongations the age of Child carries little negative baggage about their speech client ???
