As speech is a complex motor skill, the principles of motor learning (PMLs) should also be applied to dysar-thria management in order to improve treatment efficacy and maximize patient outcomes. Many factors tend to improve immediate performance during our sessions: However, while these teaching strategies can improve accuracy during the session, they can hinder long-term learning! Data on motor and verbal learning suggest that frequent feedback during acquisition may actually degrade performance on long-term retention and generalization. • 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 Read more about Motor Learning Principles in Speech Production Treatment for Persons with Dysarthria; Hypernasality in Dysarthrias. The Principles of Motor Learning are not unique to Childhood Apraxia of Speech. McAllister Byun, T., Swartz, M. T., Halpin, P. F., Szeredi, D., & Maas, E. (2016). Research indicates that providing feedback less often (low frequency) is better for long-term retention of the skill. 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. Lengthened and disrupted coarticulatory transitions between sounds and syllables. The core impairment in planning and/or programming spatiotemporal parameters of movement sequences results in errors in speech sound production and prosody” (ASHA, 2007). Childhood Apraxia of Speech (CAS) is a motor speech disorder due to a deficit in motor planning and programming speech movements. Both groups viewed visual-acoustic biofeedback (spectograms) of their auditory production in real-time. Focusing attention inward means paying attention to how the body is moving (Maas et al). We should be careful when providing feedback about performance. (2016). Providing feedback to enhance knowledge of results. Rate, rhythm, and stress are disrupted in ways specifically related to the type of dysarthria (e.g. Articulation therapy for dysarthria: Part 1. Learning Outcomes You will be able to determine which treatment approach is most appropriate based on type of dysarthria impairment determine when to apply principles of motor learning, including practice and feedback schedules Our patient’s focus of attention can be internal to their own body or external. Did you know that you can improve your patient’s outcomes by using the right focus and feedback? 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. Free download: Motor learning for articulation therapy (cheat sheet). Motor learning for articulation: Focus and feedback. They also suggest that positive changes in behaviors that are associated … due to muscle weakness and incoordination, No difficulty with involuntary motor control for chewing and swallowing, Inconsistencies in speech performance – the same word may be produced several different ways. Feedback can be provided by the clinician (or other people) or be instrumental. New York: Thieme-Stratton. 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. Listen to a baseline recording, then make a new recording and compare. Omissions in final position more likely than initial position. Treatment of articulation errors may follow a “traditional” articulation therapy approach. Teaching methods in line with the principles of motor learning include: Using these teaching methods is likely to reduce the accuracy during our sessions, particularly in the beginning. Motor execution is controlled by areas such as the cerebellum, basal ganglia, motor cortex and the motor units in the muscles. “Be Clear” is an intensive dysarthria treatment program for adults with nonprogressive dysarthria. 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). Repeating the same movement many times in a row. Timed Agenda Minutes 1-3 Introduction Minutes 4 … AB - This systematic review of the literature addresses interventions for dysarthria that focus on the global aspects of speech. treatment that incorporates principles of motor learning on speech characteristics of an individual with spastic dysarthria secondary to a traumatic brain injury (TBI). is a set of processes associated with practice or experience leading to relatively permanent changes in the capability for movement (Schmidt & Lee, 2005). Differential Diagnosis of Pediatric Speech Disorders Apraxia, Dysarthria, Phonological Disorder and Articulation Disorder, No difficulty with involuntary motor control for chewing, swallowing unless there is an oral apraxia, Difficulty with involuntary motor control for chewing, swallowing, etc. Individuals with dysarthria may benefit from frequent and intense practice consistent with the principles of motor learning to enhance retention of speech skills (Bislick, Weir, Spencer, Kendall, & Yorkston, 2012; Kleim & Jones, 2008; Maas et al., 2008). ( Duffy, 2005; Maas et al, 2008). Investigating the use of traditional and spectral biofeedback approaches to intervention for /r/ misarticulation. Principles of motor learning (PMLs) refer to a set of concepts which are considered to facilitate the process of motor learning. Although it is possible that principles of motor learning affect speech and nonspeech motor learning differently, this is an empirical question that warrants further research. Because how we direct our patient’s attention and the feedback we give can have a big influence on the outcomes. Delaying feedback by a few seconds appears to be more beneficial than providing immediate feedback. For example: We don’t actually know what the best external focus of attention on speech would be. powerpoint presentation, Speech, Physical Clues Guide Dysarthria Dx. All five of these children are demonstrating a speech sound disorder that impacts their ability to communicate clearly. Why is this? As speech-language pathologists, our goal is to help people regain the ability to talk as normally as possible. Providing feedback to enhance knowledge of performance. Monotone voice, difficulty controlling pitch and loudness. 3. Speech: Am I pressing my lips together correctly as I make the /p/ sound? Vowel distortions not as common, Number of errors increases as length of word/phrase increases. Your four-year-old says, “I do” for “I go” and “tup” for “cup.” And your five-year-old says, “wabbit” for “rabbit.”. Simply, the child knows what they want to say, but cannot plan the motor movements or move their articulators with the right speed at the right time with the right force. 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. High frequency feedback works well with blocked practice. Research on learning skills involving the body indicates that, in most cases, knowledge of results is better than knowledge of performance. The child’s speech may be slurred or distorted and the speech may range in intelligibility, based on the extent of neurological weakness. However research indicates that long-term outcomes will be better. An external focus of attention leads to more accurate and less variable performance. 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. This program was developed to take into account the new knowledge of both neuroplasticity AND principles of motor learning, using the strategy of “Clear Speech.” Shriberg, et.al., 2017 found that Lexical stress errors are a result of a deficit at the motor planning and / or programming stage. Learning Outcomes 1. But we don’t yet have a solid understanding of how all the principles apply to speech production. But as soon as our patient is achieving success, we should switch our teaching strategies to enhance long-term learning. ARTICULATION DISORDER There was no different between groups, and 6 of 9 children showed improvement. Speech: Did my client say the /p/ sound correctly? The correct diagnosis will allow for the appropriate treatment approach. 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. Phonology is the study of the sound system of a language and it tells us the rules that govern how sounds fit together to form words. Slow rate of speech. WDS/Congenital Suprabulbar Paresis. Pay attention to own speech production and make occasional judgments. Research Quarterly for Exercise and Sport, 72, 132–142. The external focus group was instructed to watch the monitor, while the internal focus group received articulatory placement cues. (Maas et al, 2008). - Sequential Motor Rate (SMR) (sensitive, especially when compared with Alternating Motion Rate (AMR) tasks) - Conversational speech and reading aloud (determine the effects of prosodic errors) - Repeating words of increasing length (fan - fancy -fanciful - fancifully) Learn how your comment data is processed. Tendency for omissions in initial position (difficulty achieving initial articulatory configurations), Errors may include substitutions, omissions, distortions, etc. Limbs: Did my client swing the golf club correctly? (Duffy et al, 2005; Maas et al, 2008), High frequency feedback may be better in the earliest stages of learning, and should be immediate and specific. We should provide specific feedback about articulation errors rather than simply indicating it wasn’t correct. Summarize how the principles of motor learning affect the treatment of motor speech disorders. Hodges, N. J., & Franks, I. M. (2001). (Brief Article), (This syndrome expresses itself, in part, as a form of dysarthria), Worster Drought Syndrome Speech: Did my client move their lips correctly? Giving frequent, immediate, and specific feedback. May be less precise in connected speech than in single words- resulting in reduced intelligibility with increased length of utterance. 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. • Schema Theory – A prominent theory of motor control and learning. The Principles of Motor Learning are not unique to Childhood Apraxia of Speech. Yet, these children are presenting with very different speech disorders, each one requiring a specific treatment. If someone wants to improve talking, then they have to talk (a lot). Invaluable for parents, speech language pathologists, teachers and all those who care about a child with apraxia. DOI: 10.1044/1058-0360(2008/025) Corpus ID: 2981254. New York: Thieme-Stratton. Principles of motor learning in treatment of motor speech disorders. Following principles of motor learning, feedback: focuses on the results – did you hit the target: yes or no? Limbs: Am I moving my arm correctly as I swing the golf club? An exception is in the earliest stages of learning, when specific, immediate, and frequent feedback can help people. Limbs: Did my client twist their hips correctly? AOS may involve a … …recovery of speech in people with MSDs, at least when they have a nonprogressive disease, requires speaking, and probably lots of it. Errors include substitutions, omissions, additions and repetitions. It is hypothesized that these principles can be applied to support disordered motor … (Maas et al, 2008; McAllister Byun et al, 2016), The research for limb movement strongly supports an external focus of attention. The four-year-old may be diagnosed with a phonological disorder and the last child likely presents with an articulation disorder. Second, it is unknown whether impaired motor systems are sensitive to the same principles of learning as intact motor systems. 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 Motor speech disorders: Substrates, differential diagnosis, and management. Therapy would focus on practicing syllables, words, and phrases using varying prosodic contours. ... Motor learning and practice.. Champaign, IL. Phonological treatment approaches (e.g., Distinctive Features, Cycles, Minimal Contrasting Pairs) target a group of sounds with similar error patterns (e.g., fronting: d/g: do/go, t/k “tup”/cup), although the actual treatment may target individual sounds. “Be Clear” is an intensive dysarthria treatment program for adults with nonprogressive dysarthria. The program was set up to complete 1 hour sessions 4x/week for 4 weeks. Treating Dysarthria in Children.
