Treating Vowels: A Tactile Treatment Program (Part III)

The second part of Sam’s treatment for vowels was the speech production or articulation portion.  We began by targeting the round vowels such as /Ʊ/.  A lesson plan was created that included auditory bombardment, production of the sound in isolation with PROMPT and tactile cues, production of the sound in words using a functional or communication task, and production of the sound in a word using drills.

For the round vowels multiple tactile cues were provided to elicit the lip rounding.  The TalkTools Tactile Tubes were particularly helpful.  Since they come in different diameters, different tubes were used to elicit different sounds.  Initially the use of Renee R. Hill’s and Sara R. Johnson’s Ice Stick was also very helpful to elicit lip rounding.  The added thermal stimulation provided by the cold Ice Stick yielded some good results.  The Ice Stick placed horizontally was used to elicit lip retraction for vowels such as /i/.  In addition, two Bite Blocks placed between the molars simultaneously on both sides also assisted with stabilizing the jaw height while aiding lip retraction.

Following the principals of Hodson and Paden’s Cycle’s Approach, a vowel was targeted for a few weeks and then a new vowel was selected.  Once all the sounds were targeted, the same targets were then re-cycled.  The functional or communication tasks were the highlight of the session.  This portion is important since it gives us as therapists the opportunity to shape the sound in one phonetic context using multiple trials.  For example, when targeting the “ee” sound, I used the Honey Bee Tree game.  I worked on the words “tree” and “leaf” when Sam placed the leaves on the tree.  When he pulled the leaves out and the bees fell, I targeted the word “bee.”  I try to elicit the word at least 8-10 times per activity.  In a half hour session, I try to include at least 4-5 similar communication activities.  Apart from being able to target the same word through multiple repetitions, the communication task also gives the child an opportunity to use the sound in a meaningful way rather than simply naming pictures in a drill.

As a part of the generalization portion of the lesson, I would have Sam’s parent lead one of the activities in the clinic (so Sam can produce the target word with a person other than me) and I also provided the parents with a copy of the drill pictures to practice at home.

Treating Vowels: A Tactile Treatment Program (Part II)

When Sam began therapy he had difficulty tolerating any sensory input in or near is mouth. Bringing a toothette close to his mouth would lead to an involuntary tongue protrusion to resist any stimulation. Placing a bite block between his molars would lead to gag reflex. My first goal therefore was to decrease his tactile defensiveness, while building his proprioceptive awareness (knowing where his lips, tongue and jaw are in space) of his oral structures. The first step of course, was to build his trust and comfort level with me and the tools I would use. We named the toothette with the vibrator “Mr. Tickles.” Mr. Tickles would always start the session. Sam could tell Mr. Tickles where he wanted to be tickled. We would usually start with the palm of his hand or his arm and gradually work our way to his mouth. Within a few sessions, Sam could tolerate several minutes of stimulation with a toothette without any negative reactions.

vibrator-tootethOnce Sam’s tactile defensiveness was significantly reduced, my next goal was to stabilize his jaw and increase jaw grading (i.e. opening and closing of his mouth to various jaw heights without jaw sliding or jerking). Since Sam tended to “fix” his jaw at jaw height 1 (closed mouth position) during speech, my objective was to move him gradually through Sara R. Johnson’s Bite Block hierarchy. Unless Sam was able to lower his jaw to jaw height 3 or 4, production of vowels such as /Ɔ/ would be challenging. We started with Bite Block #2 and within several weeks were able to move to Bite Block #6, which requires considerable jaw opening. Sam can now hold a lower jaw position without sliding. As a part of a comprehensive oral motor or oral placement program, we also worked on lip rounding, lip seal and tongue retraction. Sara R. Johnson’s Horn and Straw Hierarchy’s were employed for this purpose. In addition, a tongue depressor with added “weights” (pennies taped to both ends) were used to build lip strength and lip closure.

Treating Vowels: A Tactile Treatment Program (Part I)

Sam came in with a diagnosis of Autism Spectrum Disorder and Apraxia of Speech. During the initial intake over the phone, his mother informed me that her main concern for Sam’s speech was his vowel production. And sure enough, all of Sam’s vowels were substituted by a neutral /Ʌ/. There was no discrimination even for round vowels like /Ʊ/ or /Ɔ/. On further observation, it was evident that Sam had oral motor deficits. There was limited if any jaw grading. He tended keep his jaw height at 1 for all his words. His lips did not appear to dissociate from his jaw with no rounding or retraction. Similarly, tongue and jaw dissociation was also limited. Basically, he used his jaw to elevate his tongue. For vowels, the tongue stayed at the floor of his mouth with little to no tongue elevation. Sam had difficulty imitating non-speech oral postures such as a lip pucker, smile, a wide open mouth, even with visual cues like a mirror. It was clear that using purely auditory and visual models to increase his vowel repertoire was a path to frustration and limited success. I therefore planned a unique treatment program that used a two pronged approach:

  • Building sensory awareness, increasing strength, coordination, grading and dissociation skills,
  • Using tactile approaches (P.R.O.M.P.T, TalkTools Therapy Tactile Tools for Apraxia of Speech and TalkTools Ice Stick) to build speech production for vowels.

Cycles Approach

Cycles Approach to treating multiple articulation errors in children with poor speech intelligibility

Children often demonstrate errors in the production of sounds like /s/, /r/ and /l/. When a child presents with a few specific sound errors, a traditional articulation treatment is warranted. However, for some children the sound error includes a wide range of sounds and severely impacts their speech intelligibility. Their errors often follow patterns such as omission of final sounds in words (e.g. saying “ca” for “cat.”). Hodson and Paden (1991) proposed the “Cycles Approach” in which these patters are targeted in a specific sequence. The treatment includes specific treatment strategies used in each session such as auditory bombardment, a communication activity, drills and a generalization activity. Evidence suggests that treatment approaches that target patterns of sounds rather than each specific misarticulated sound for children with multiple errors are more efficient thereby reducing the overall treatment time. The more dramatic impact of using an approach such as the Cycles Approach is a significant impact in the child’s speech intelligibility. This video (Thank You, Sonali!) is a “Before and After Cycles Program” of a child (age 3 years). The little girl demonstrated multiple sound errors using essentially vowels to communicate. Following several months of intervention, she could produce complete sentences that are intelligible even to unfamiliar persons. The remarkable difference in her speech is impressive evidence of the overall effectiveness of the program.

Hello world!

I am so excited to finally launch my website. I want to officially thank everyone who helped make my vision a reality. I thought I’d write this blog to share ideas and techniques with parents and other speech language therapists. Thank you for reading and I can’t wait to hear your comments.
