Now I have enough information to give a comprehensive answer. Let me compile this.
Non-Speech Oromotor Exercises (NSOMEs/NSOMTs) Across Special Populations
Definition
Non-speech oral motor exercises (NSOMEs/NSOMTs) are therapeutic activities that do not require production of a speech sound but are used to influence the physiological underpinnings of the oropharyngeal mechanism. They involve sensory stimulation to, or active/passive movements of, the lips, jaw, tongue, soft palate, larynx, and respiratory muscles (ASHA/McCauley et al., 2009).
Common Types of NSOMEs Used Clinically
| Category | Examples |
|---|
| Lip exercises | Pucker/smile, lip stretching, lip pressing, lip vibration (raspberries), horn blowing, bubble blowing |
| Tongue exercises | Tongue push-outs, tongue wags (side to side), tongue tip elevation, tongue curling/lateralization, tongue resistance with depressor |
| Jaw exercises | Bite block grading, jaw opening/closing against resistance, chewing simulation |
| Cheek exercises | Cheek puffing, cheek sucking, cheek retraction |
| Blowing exercises | Blowing horns, windmills, whistles, bubbles (for breath support/VP function) |
| Sensory stimulation | Oral massage, vibration (vibratory devices/toothettes), icing, tapping |
| Suction exercises | Straw drinking with varying viscosities, suction on swabs |
| Palatal exercises | Yawn/swallow for soft palate elevation, K/G target placement |
NSOMEs by Special Population
1. Cerebral Palsy (CP)
Goals: Reduce hypotonia/hypertonia of orofacial muscles, improve jaw grading, lip closure, tongue control, and feeding.
- Jaw grading with bite blocks (increasing resistance levels) — Rosenfeld-Johnson hierarchy
- Lip closure exercises — lip press against spatula, horn blowing sequences
- Tongue lateralization — tongue to corner of mouth with/without resistance
- Oral sensory stimulation — icing, vibration to normalize tone before feeding/speech
- Cheek support (external) combined with oral motor tasks to assist jaw stability
- Straw hierarchies — progressive straw thickness/length to build lip/buccal strength
- Note: In spastic CP, tone-reduction techniques (slow, rhythmic massage) precede active exercises; in hypotonic CP, facilitory/alerting input (tapping, vibration) is used first
2. Down Syndrome
Goals: Address hypotonia, tongue protrusion, open mouth posture, drooling, and feeding difficulties.
- Tongue retraction exercises — encouraging posterior tongue placement; resistance tongue pushes
- Lip strengthening — lip press, button pull, Oral Motor Resistive Lip exercises
- Jaw stability work — bite blocks, jaw closure against light resistance
- Blowing exercises — bubbles, horns (for velopharyngeal function and breath support)
- Oral sensory input — vibration to increase sensory awareness and reduce tongue protrusion
- Cheek/buccal exercises — puff cheeks, cheek retraction
- Note: NSOMEs are among the most frequently used interventions for this population by SLPs (Lof 2008; Hodge 2005), though evidence remains limited
3. Autism Spectrum Disorder (ASD)
Goals: Address sensory hypersensitivity/hyposensitivity, feeding selectivity, and oral awareness deficits (not speech sound disorders per se).
- Desensitization hierarchy — gradual introduction of oral stimuli (finger, toothbrush, NUK tool) to normalize tactile tolerance
- Vibration applied externally (cheeks, lips) to increase sensory awareness
- Lip and tongue imitation games — used in structured play to build motor imitation skills
- Blowing/sucking — through straws, resistance tools, for breath control
- Note: NSOMEs in ASD are primarily justified for feeding/sensory goals rather than speech sound production; evidence for speech-specific outcomes is lacking
4. Traumatic Brain Injury (TBI) — Acquired Dysarthria
Goals: Remediate weakness, incoordination, or reduced range of motion from neurological damage.
- Lip strengthening — lip press, button pull, lip tug with button and string
- Tongue range of motion — tongue protrusion, lateralization, elevation to alveolar ridge against resistance
- Jaw exercises — progressive bite blocks for hypokinetic jaw
- Respiratory muscle exercises — diaphragmatic breathing, Expiratory Muscle Strength Training (EMST) — though EMST involves breath support and has better evidence than many NSOMEs
- Oral sensory facilitation — vibration/icing for reduced oral sensation
- Note: For TBI-related dysarthria, NSOMEs are often used as warm-up adjuncts; evidence for direct speech benefits remains insufficient (Kent 2015; Hodge 2002)
5. Stroke — Acquired Dysarthria/Dysphagia
Goals: Restore orofacial strength and coordination post-stroke, support swallowing rehab.
- Lip exercises — lip stretching, pursing, resistance exercises
- Tongue exercises — tongue push-outs, lateralization, elevation (using tongue depressor for resistance)
- Jaw exercises — active ROM, jaw open/close against resistance
- EMST (Expiratory Muscle Strength Training) — 75% effort threshold, has RCT evidence for both dysarthria and dysphagia post-stroke
- Masako maneuver / effortful swallow — though more swallowing-targeted, involves oral/pharyngeal motor exercise
- Oral massage — for facial hemiplegia, to maintain tone
- Note: NSOMEs are widely used by Australian and UK SLPs for acquired dysarthria (Gracia et al., 2020; Mackenzie et al., 2010), but high-quality RCT evidence supporting direct speech gains remains limited
6. Parkinson's Disease (PD)
Goals: Address hypokinetic dysarthria, hypomimia, and orofacial rigidity.
- Facial expression exercises — exaggerated smile, raised eyebrows, lip stretching
- Tongue ROM drills — maximum tongue protrusion, lateralization, elevation
- Loud/exaggerated articulation warm-ups (LSVT LOUD adjunct)
- Lip and cheek exercises — pucker/spread, cheek puffing
- Jaw ROM — exaggerated opening, resistance jaw exercises
- Note: NSOMEs in PD are most commonly used as a warm-up before speech tasks or LSVT LOUD sessions; they are not a standalone evidence-based treatment for hypokinetic dysarthria
7. Cleft Palate (Pre- and Post-Surgery)
Goals: Pre-surgically, maintain oral motor mobility; post-surgically, improve velopharyngeal function and reduce hypernasality.
- Blowing exercises (e.g., bubbles, horn kits) — to stimulate VP closure; historically common but evidence is poor (Ruscello & Vallino, 2020)
- Sucking exercises — straw hierarchies, maintaining sucking reflexes in infants
- Palatal lift stimulation — tactile stimulation to soft palate
- Lip strengthening — post-repair, when lip scarring limits mobility; lip press, button pull
- Note: NSOMEs for velopharyngeal inadequacy are not supported by current evidence; behavioral speech therapy (pressure consonant drilling) is preferred
8. Hearing Impairment
Goals: Build orofacial motor awareness for articulatory placement that cannot be adequately monitored auditorily.
- Lip and tongue placement exercises — tactile feedback tools (TalkTools), visual biofeedback (mirror)
- Jaw grading — bite blocks to establish stable jaw for vowel production
- Vibrotactile stimulation — vibration to lips/cheeks for sensory-motor awareness
- Breath control exercises — controlled blowing, controlled exhalation tasks
- Note: Tactile-kinesthetic approaches have rationale in hearing-impaired children where auditory feedback is limited, though direct evidence is sparse
9. Intellectual Disability (General) / Developmental Delay
Goals: Improve oral muscle tone, feeding skills, and drooling management.
- Oral sensory desensitization — graduated sensory stimulation (NUK brush, vibrator)
- Lip closure — lip press against depressor, horn blowing
- Tongue exercises — tongue clicks, tongue elevation with visual cue
- Chewing simulation — Tri-Chew or Z-Vibe tools for jaw grading and bilateral chewing
- Jaw stabilization — bite blocks, jaw support techniques
10. Voice Disorders (Functional/Neurological)
Goals: Improve breath-voice coordination and laryngeal muscle function.
- Straw phonation — semi-occluded vocal tract exercise (SOVTE); has evidence for resonance and vocal fold closure
- Lip trills / tongue trills — SOVTE for vocal warm-up and reducing laryngeal tension
- Humming with lip seal — gentle phonation with increased back-pressure
- Note: Straw phonation and lip/tongue trills are classified as "semi-occluded vocal tract exercises" and have stronger evidence than most other NSOMEs
Evidence Summary & Clinical Implications
| Population | NSOME Use | Evidence Level |
|---|
| Cerebral Palsy | Common (muscle tone, feeding) | Low–Moderate |
| Down Syndrome | Very common (hypotonia) | Low |
| ASD | Used for sensory/feeding goals | Very Low |
| Acquired Dysarthria (Stroke/TBI) | Used as adjunct warm-up | Low |
| Parkinson's Disease | Warm-up before LSVT | Low |
| Cleft Palate | Largely not supported for VP | Very Low–No evidence |
| Hearing Impairment | Tactile-kinesthetic rationale | Low |
| Intellectual Disability | Feeding/tone management | Low |
| Voice Disorders | SOVTE (straw/lip trills) | Moderate |
Key clinical consideration: The evidence base for NSOMEs improving speech sound production is consistently weak across all populations (McCauley et al., 2009; Lof 2008; Cochrane systematic review, 2019). NSOMEs are better justified for feeding, swallowing, sensory normalization, tone management, and drooling control — and should be used adjunctively rather than as standalone speech interventions. ASHA does not endorse NSOMEs as evidence-based practice for speech sound disorders.
