Understanding Motor Speech Disorders in Children
Motor speech disorders occur when the neurological pathways responsible for planning, programming, or executing speech movements are disrupted. Unlike language disorders—where a child struggles with vocabulary or grammar—or simple articulation errors, motor speech disorders affect the fundamental ability to coordinate the rapid, precise movements of the jaw, tongue, lips, and soft palate required for intelligible speech.
At Front Range Speech in Greeley, Colorado, we specialize in the differential diagnosis and treatment of pediatric motor speech disorders. Accurate identification is critical because these conditions require fundamentally different therapeutic approaches than other speech and language diagnoses. Our clinicians hold advanced training in motor speech assessment protocols and evidence-based treatment methods.
Childhood Apraxia of Speech (CAS)
Childhood Apraxia of Speech is a neurological motor speech disorder that affects approximately 1–2 children per thousand. The core deficit in CAS lies in the brain's ability to plan and program the spatiotemporal parameters of speech movements—the sequences, timing, force, and range of articulatory gestures needed to transition smoothly between sounds and syllables.
Children with CAS typically present with three consensus-based features identified by the American Speech-Language-Hearing Association (ASHA): inconsistent error patterns on both consonants and vowels, disrupted coarticulatory transitions between sounds and syllables, and inappropriate prosody, particularly in lexical and phrasal stress patterns. Many children also demonstrate vowel distortions, limited phonetic inventories, and a significant expressive-receptive language gap.
Families throughout Greeley, Loveland, Fort Collins, Windsor, and the broader Northern Colorado region trust Front Range Speech for CAS evaluation and treatment because we follow the latest research from leaders in the field and apply motor learning principles systematically to every session.
Evidence-Based Treatment Approaches
Tailored protocols for each child's unique motor speech profile
DTTC (Dynamic Temporal and Tactile Cueing)
DTTC is an evidence-based treatment designed specifically for children with moderate to severe CAS. Developed by Dr. Edythe Strand, DTTC uses a systematic cueing hierarchy that begins with simultaneous production and gradually fades support as the child gains motor control. Tactile cues guide articulatory placement, while temporal cues shape the rhythm and rate of speech movements, building accurate, independent motor plans through carefully scaffolded practice.
PROMPT Therapy
PROMPT (Prompts for Restructuring Oral Muscular Phonetic Targets) is a tactile-kinesthetic approach that uses precise touch cues on the face, jaw, and neck to guide the articulatory movements needed for speech. By providing direct physical input to the motor system, PROMPT helps children develop and refine the motor maps for speech sounds, syllable shapes, and connected speech. This approach is particularly effective for children who struggle with volitional control of speech movements and benefit from external sensory feedback.
ReST (Rapid Syllable Transition Treatment)
ReST is a treatment protocol developed at the University of Sydney that specifically targets two hallmark deficits of CAS: difficulty with smooth transitions between syllables and impaired control of speech rhythm and stress. Using nonsense words of increasing length and complexity, ReST trains children to produce accurate syllable sequences with appropriate prosodic patterns. Research demonstrates that ReST produces gains that generalize to untrained words, making it a powerful tool for building flexible motor speech skills.
Dysarthria in Children
Pediatric dysarthria results from weakness, spasticity, or incoordination of the muscles used for speech, typically secondary to neurological conditions such as cerebral palsy, traumatic brain injury, or neuromuscular disorders. Unlike CAS, where the muscles themselves are not weak, dysarthria involves impaired muscular execution that can affect respiration, phonation, resonance, articulation, and prosody—any or all of the speech subsystems.
Treatment for dysarthria focuses on maximizing the strength, coordination, and efficiency of the speech mechanism. Depending on the type and severity, intervention may include respiratory-phonatory coordination exercises, rate control strategies, articulatory strengthening, and compensatory techniques. For children with severe dysarthria, we integrate augmentative and alternative communication (AAC) to ensure functional communication while continuing to develop oral speech skills.
Ataxic Speech and Cerebellar Involvement
Ataxic dysarthria, associated with cerebellar dysfunction, produces a distinctive speech pattern characterized by irregular articulatory breakdowns, excess and equal stress on syllables, and a scanning or robotic quality to speech rhythm. Children with ataxic speech may sound as though they are producing each syllable with equal emphasis, losing the natural melody and flow of conversational speech. Our clinicians are experienced in identifying and treating the unique prosodic and coordinative challenges that cerebellar involvement presents.
The Importance of Differential Diagnosis
Distinguishing between CAS, dysarthria, phonological disorders, and other speech conditions is one of the most challenging tasks in pediatric speech-language pathology—and one of the most consequential. A child misdiagnosed with a phonological disorder who actually has CAS will receive treatment that is unlikely to produce meaningful progress, leading to frustration for the child and family and lost time during critical developmental windows.
At Front Range Speech, our motor speech evaluations include dynamic assessment of volitional speech movements, analysis of error consistency across repeated productions, assessment of prosodic accuracy, oral mechanism examination, and standardized testing. We serve families across Greeley, Evans, Garden City, Johnstown, Milliken, and surrounding Northern Colorado communities who are seeking answers about their child's speech development.
What to Expect from Motor Speech Therapy
Motor speech therapy at Front Range Speech is structured around principles of motor learning: high repetition, distributed practice, variable practice conditions, and appropriate feedback schedules. Unlike traditional articulation therapy, which may target individual sounds in isolation, motor speech therapy focuses on movement sequences—helping the child's brain build and refine the motor programs needed for connected, functional speech.
Sessions are intensive, engaging, and tailored to each child's current level of motor speech control. We set measurable goals, track progress with data at every session, and adjust our approach as the child advances. Parent involvement is essential—we train caregivers in cueing strategies and structured home practice so that motor learning continues between sessions.
Serving Greeley and Northern Colorado
Front Range Speech provides specialized motor speech therapy to families throughout the Northern Colorado region, including Greeley, Fort Collins, Loveland, Windsor, Johnstown, Milliken, Evans, and surrounding communities. If your child has been diagnosed with Childhood Apraxia of Speech, dysarthria, or another motor speech disorder—or if you suspect a motor speech difficulty—contact us for a comprehensive evaluation. Early, accurate diagnosis and intensive, evidence-based treatment give children the best opportunity to develop clear, confident communication.
