Emphasize our own movements and ask them to imitate. Childhood Apraxia of Speech (CAS) is a motor speech disorder due to a deficit in motor planning and programming speech movements. CAS may occur as a result of known neurological impairment, in association with complex neurobehavioral disorders of known and unknown origin, or as an idiopathic neurogenic speech sound disorder. Invaluable for parents, speech language pathologists, teachers and all those who care about a child with apraxia. (Maas et al, 2008). Then as soon as they have success, we can have them repeat the movement without the external cueing and then move into an external focus of attention. Motor learning of volitional nonspeech oral movements: Interoral pressure and articulatory kinematics; Oral-motor learning, retention, and transfer as a function of attentional focus; Principles of Motor Learning Applied to the Treatment of Acquired Apraxia of Speech: Effects of Feedback Frequency and Timing Good control of pitch and loudness, not limited in inflectional range for speaking, May have Inappropriate vocal quality according to type of Dysarthria. But don’t provide high frequency feedback for too long! Research Quarterly for Exercise and Sport, 72, 132–142. Duffy goes on to say that specific feedback seems to be more helpful than general feedback. Omissions in final position more likely than initial position. Research indicates that providing feedback less often (low frequency) is better for long-term retention of the skill. Conclusions: These data suggest that people with dysarthria secondary to traumatic brain injury can respond positively to an intensive speech treatment implementing principles of motor learning. Therapy includes breathing sessions, phonetic training, and oral-facial exercises. Treatment of Developmental Apraxia of Speech: Application of Motor Learning Principles. Sept 8 Principles of Motor Learning Maas et al. Google Scholar. – Generalized Motor Programs (GMP) – Parameters • The . • Incorporate principles of motor learning, including practice and feedback schedules to enhance carry over and retention of acquired skills • Describe levels of evidence available to support several classes of interventions for dysarthria and identify sources for updates on EBP ©2018 MFMER | slide-4 Treatment of Dysarthria Evidence supports that motor learning principles may be associated with increases in speech intelligibility, precision of articulatory movements and voice quality and clarity for children with moderate and severe dysarthria” (Pennington, L., Parker, N. K., et al. New York: Thieme-Stratton. In general, we should try to direct our patients to focus on something task-related beyond how their mouth is moving. dysarthria treatment, Patients whose dysarthria is more severe, however, may have to learn to use alternative forms of communication. The principles of motor learning underlie evidence-based treatment programs for dysarthria (e.g., LSVT LOUD) and apraxia of speech (e.g., Sound Production Treatment). Summarize how the principles of motor learning affect the treatment of motor speech disorders. There’s more to articulation therapy for dysarthria than manipulating how your patient speaks. Both groups viewed visual-acoustic biofeedback (spectograms) of their auditory production in real-time. They go on to say that knowledge of results “may be critical later in therapy and for clients who can better evaluate their own errors” (p. 289). The limited gains on speech of patients with STN-DBS observed in our study can be due to differences in the pathophysiology of dysarthria, the sensory processing or the ability for motor learning. Dysarthria is a motor speech disorder resulting from neurological injury of the motor component of the motor–speech system and is characterized by poor articulation of phonemes. We should provide specific feedback about articulation errors rather than simply indicating it wasn’t correct. “Be Clear” is an intensive dysarthria treatment program for adults with nonprogressive dysarthria. Your five-year-old speaks in a very slow and halting manner and there does not appear to be a pattern to his errors: sometimes he says the word correctly and other times he does not. Learn how your comment data is processed. Google Scholar. A child can have too much tone (spasticity) or too little low tone (hypotonicity). Consistent errors that can usually be grouped into categories (fronting, stopping, cluster reduction, etc). Speech inconsistency is a core feature of CAS, according to Iuzzini-Siegel, Hogan, Green, JSHR, 2017 and Grigos, Moss, Lu, JSHLR, 2015. In other words, it is a condition in which problems effectively occur with the muscles that help produce speech, often making it very difficult to pronounce words. Some treatment approaches for dysarthria have strong research evidence to support them, while others are supported by theory and limited but (hopefully) growing evidence. Remediation of Severe Dysarthria. Encouraging an external focus of attention. Limbs: Did my client twist their hips correctly? For example: Alternatively, an external focus of attention means paying attention to some effect of the movement. from nonspeech motor-learning research. Purpose There has been renewed interest on the part of speech-language pathologists to understand how the motor system learns and determine whether principles of motor learning, derived from studies of nonspeech motor skills, apply to treatment of motor speech disorders. Motor Learning • Motor learning . Errors are generally consistent as length of words/phrases increases, Well rehearsed, “automatic” speech is easiest to produce, while “on demand” speech most difficult, No difference in how easily speech is produced based on situation, Receptive language skills usually better than expressive skills, Typically receptive and expressive language skills are commensurate, As phonological disorders are language based, there may be differences between receptive and expressive language. Treatment based on non-speech oral motor exercises has not by proven effective in working with children with CAS (McCauley, Strand, Lof, Schooling, Frymark, AJSLP, 2009). McAllister Byun, T., Swartz, M. T., Halpin, P. F., Szeredi, D., & Maas, E. (2016). Investigating the use of traditional and spectral biofeedback approaches to intervention for /r/ misarticulation. There are several types of pediatric dysarthria with varying characteristics. They also suggest that positive changes in behaviors that are associated … Slow rate of speech. Speech following STN-DBS can be perceptually different from the hypokinetic dysarthria initially described by Darley and colleagues 2 , 13 . Speech: Am I pressing my lips together correctly as I make the /p/ sound? If someone wants to improve talking, then they have to talk (a lot). The program was set up to complete 1 hour sessions 4x/week for 4 weeks. Giving frequent, immediate, and specific feedback. Shriberg, et.al., 2017 found that Lexical stress errors are a result of a deficit at the motor planning and / or programming stage. For example, we could give feedback related to: Knowledge of performance: the correctness of body movement. I’m sure we’ve all had the experience of a client improving their speech in the therapy room without carrying it over into their day-to-day life. The fine motor movements that control respiration (breathing), phonation (movement of the vocal cords during speech), resonance (nasality) and articulation (lips, cheeks, throat, velum, and larynx) are affected. Inappropriate prosody, especially in the realization of lexical or phrasal stress. (Brief Article), (This syndrome expresses itself, in part, as a form of dysarthria), Worster Drought Syndrome Speech: Did my client say the /p/ sound correctly? Tendency for omissions in initial position (difficulty achieving initial articulatory configurations), Errors may include substitutions, omissions, distortions, etc. For example, we could give feedback related to: Knowledge of results (feedback) is crucial to motor learning, especially in its early stages. (2016). The child’s speech may be slurred or distorted and the speech may range in intelligibility, based on the extent of neurological weakness. Why is this? Direction of attentional focus in biofeedback treatment for /r/ misarticulation. A child who has a phonological disorder has not learned how these sounds fit together to produce words. May be less precise in connected speech than in single words- resulting in reduced intelligibility with increased length of utterance. Childhood apraxia of speech may be the result of an inability to learn and control motor planning of speech. ( Duffy et al, 2005; Maas et al, 2008). ... Dysarthria and apraxia (pp. Knowledge of results: the correctness of the outcome in relation to the goal. Required fields are marked *. © 2018 Lisa A Murray | All rights reserved |, Our teaching should take motor learning into account, Internal focus of attention versus external, Two types of feedback: Results versus performance, When knowledge of performance may be helpful, What works best in therapy may not be best for outcomes, Articulation therapy for dysarthria: Part 1, How to plan cognitive therapy with 6 questions, 50 questions to ask in a home health SLP interview, 10 factors that increase risk of aspiration pneumonia. If your teaching isn’t in line with the principles of motor learning, consider trying out some new strategies. Rate, rhythm, and stress of speech (Prosody) are disrupted, some groping for placement, especially prior to and during intentional speech. Possible options include paying attention to how the speech sounds, observing an ultrasound of the tongue while talking, or watching a visual representation of the sound in real time. Limbs: Am I swinging the golf club correctly? ... Motor learning and practice.. Champaign, IL. These principles were derived from studies that involved nonspeech motor tasks, most with intact motor systems. We may use the above strategies in the earliest stages of learning, or at the very beginning of sessions early in treatment. An external focus of attention leads to more accurate and less variable performance. Learn principles of motor speech with free interactive flashcards. Research on learning skills involving the body indicates that, in most cases, knowledge of results is better than knowledge of performance. All five of these children are demonstrating a speech sound disorder that impacts their ability to communicate clearly. New York: Thieme-Stratton. Evidence supports that motor learning principles may be associated with increases in speech intelligibility, precision of articulatory movements and voice quality and clarity for children with moderate and severe dysarthria” (Pennington, L., Parker, N.
