Oral-Facial Practices: Complete Guide for Speech Therapists
The bucco-facial practices and oro-facial praxies are a fundamental pillar of modern speech therapy rehabilitation. These voluntary and coordinated movements of the oro-facial structures - tongue, lips, cheeks, jaw, and soft palate - are essential for articulation, feeding, swallowing, and facial expression. This comprehensive guide presents the latest therapeutic approaches, standardized assessment protocols, and a complete collection of scientifically validated progressive exercises. Aimed at speech therapists, this manual integrates recent evidence and offers practical tools that can be immediately used in practice. The application COCO THINKS and COCO MOVES from DYNSEO perfectly complements this approach with its adapted cognitive and motor stimulation modules.
1. Definition and Neurophysiological Bases of Oro-Facial Praxies
The term "praxis" originates from ancient Greek "praxis" meaning "action" or "practice." Oro-facial praxies represent the neurological ability to perform voluntary, coordinated, and finalized movements of the oro-facial structures. These non-verbal movements, distinct from actual articulation, nonetheless constitute the essential motor substrate for speech production.
From a neuroanatomical perspective, oro-facial praxies involve a complex neural network including the primary motor cortex, premotor cortex, Broca's area, basal ganglia, and cerebellum. This hierarchical organization allows for the planning, initiation, and precise execution of oro-facial movements.
Contemporary research in neuroscience demonstrates that oro-facial praxies constitute a specialized motor system, anatomically and functionally distinct from other praxic systems. This specificity justifies the importance of targeted assessment and rehabilitation in modern speech therapy practice.

2. Detailed Classification of Oro-Facial Praxies
The modern classification of oro-facial praxies is based on an anatomical and functional approach, distinguishing five main areas of therapeutic intervention. This taxonomy allows for systematic assessment and targeted therapeutic planning.
Lingual Praxies
Lingual praxies constitute the most complex and diverse group. The tongue, a highly innervated muscular organ, allows for a multitude of precise movements essential for articulation and swallowing. The assessment of lingual praxies includes the analysis of elevation, lowering, protrusion, retraction, and lateralization movements.
| Type of Movement | Examples of Exercises | Clinical Applications |
|---|---|---|
| Elevation | Touching the nose, licking the upper lip | Palatal sounds [j], [ɲ] |
| Lowering | Touching the chin, licking the lower lip | Open vowels [a], [ɔ] |
| Lateralization | Right-left movement, cheek sweeping | Lateral sounds [l], chewing |
| Protrusion | Maximum extension, vibrations | Apical consonants [t], [d] |
The use of taste substances (honey, spread) on different oral areas stimulates lingual proprioception and facilitates the learning of targeted movements. This multisensory approach optimizes gesture memorization and accelerates therapeutic progress.
Labial Praxies
Labial praxies involve the orbicular muscles and surrounding skin muscles. Mastery of these is crucial for the articulation of bilabial and labiodental consonants, as well as for saliva control and facial aesthetics.
The assessment of labial praxies includes the analysis of stretching, protrusion, compression, and labial vibration. These movements should be evaluated in terms of amplitude, precision, speed, and maintenance.
Recent research demonstrates a significant correlation between the quality of lip praxies and the articulatory precision of bilabial consonants [p], [b], [m]. Prior praxic rehabilitation can facilitate the acquisition of these phonemes in the dyspraxic child.
1. Standardized praxic evaluation
2. Targeted praxic rehabilitation (6-8 weeks)
3. Progressive articulatory integration
4. Consolidation in functional context
3. Standardized Evaluation Protocols and Diagnostic Tools
The evaluation of oro-facial praxies is a fundamental step in the speech therapy assessment. It must be systematic, standardized, and based on scientifically validated tools. The modern diagnostic approach integrates clinical observation, formal evaluation, and instrumental analysis.
Structured Clinical Observation
Clinical observation begins with the analysis of oro-facial posture at rest. This static evaluation provides information on muscle tone, facial symmetry, spontaneous tongue position, and lip competence. The examiner looks for signs of hypotonia, hypertonia, asymmetry, or dyskinesias.
Dynamic observation analyzes spontaneous movements during saliva swallowing, conversational speech, and eating. This ecological approach allows for the identification of pathological compensations and actual functional difficulties.
📊 Standardized Observation Grid
DYNSEO recommends the use of a structured observation grid comprising 25 items divided into 5 categories: posture at rest, isolated movements, gestural sequences, execution speed, and precision. This systematic approach ensures a comprehensive and reproducible evaluation.
Formal Tests and Evaluation Batteries
Formal tests allow for an objective quantification of praxic abilities. They include tasks based on imitation, verbal command, and sequences. The analysis focuses on success/failure, execution quality, and compensatory strategies used.
Contemporary evaluation batteries integrate rigorous psychometric criteria: test-retest reliability, concurrent validity, sensitivity to change. These tools enable objective monitoring of therapeutic progress and optimized interprofessional communication.
Quantitative Analysis Criteria:
- Gestural amplitude (0-100% of the expected movement)
- Spatial precision (deviation from the target)
- Execution speed (reaction time + motor time)
- Gestural fluidity (number of interruptions/corrections)
- Postural maintenance (duration of maintenance in seconds)
- Motor dissociation (associated parasitic movements)
4. Therapeutic Indications and Target Populations
The indications for oro-facial praxic rehabilitation extend to many developmental and acquired pathologies. The therapeutic approach must be personalized based on the etiology, the patient's age, and the priority functional objectives.
Developmental Disorders
In children, oro-facial praxic disorders can be part of verbal dyspraxia, global developmental delay, or specific oral language disorders. Early intervention is crucial to optimize neural plasticity and prevent the establishment of pathological compensations.
Verbal dyspraxia represents the main indication for intensive praxic rehabilitation. These children present specific difficulties in planning and executing articulatory gestures, requiring a multimodal and intensive therapeutic approach.
The integration of COCO THINKS and COCO MOVES into developmental rehabilitation protocols allows for complementary global cognitive stimulation. The visuo-spatial training modules and eye-hand coordination enhance the child's general praxic abilities.
Acquired Neurological Pathologies
Acquired neurological pathologies (Stroke, traumatic brain injury, tumors) can selectively or globally affect oro-facial praxic functions. A comprehensive neuropsychological evaluation guides therapeutic orientation and functional prognosis.
Peripheral facial paralysis constitutes a specific indication for praxic rehabilitation. The therapeutic objective aims at recovering voluntary facial motor skills, preventing synkinesis, and optimizing aesthetic function.
Post-stroke oro-facial praxic rehabilitation requires a progressive and multimodal approach. The integration of neuromuscular facilitation techniques, sensory stimulation, and functional exercises optimizes neurological recovery.
Phase 1: Passive stimulation and mobilizations
Phase 2: Assisted contractions and facilitation
Phase 3: Isolated active movements
Phase 4: Complex gestural sequences
Phase 5: Functional integration
5. Advanced Rehabilitation Techniques and Therapeutic Exercises
The rehabilitation of oro-facial praxias is based on validated neurophysiological principles: intensive repetition, graduated progression, multisensory feedback, and functional transfer. Therapeutic effectiveness depends on the quality of planning, training intensity, and patient motivation.
Basic Exercises and Progressions
Basic exercises form the foundation of praxic rehabilitation. They aim at the acquisition or recovery of elementary movements before their integration into complex sequences. Therapeutic progression follows an order of increasing difficulty: isolated movements, simple sequences, complex chains, functional integration.
Each exercise must be precisely defined in terms of objective, execution modality, success criteria, and possible progressions. This standardization ensures the reproducibility and effectiveness of the therapeutic intervention.
| Level | Objectives | Exercise Examples | Duration |
|---|---|---|---|
| Beginner | Simple isolated movements | Lingual protrusion, symmetrical smile | 2-3 weeks |
| Intermediate | Bi-gestural sequences | Right-left tongue, smile-pout | 4-6 weeks |
| Advanced | Complex chains | Sequences of 4+ movements | 6-8 weeks |
| Functional | Ecological integration | Exercises in food context | Ongoing |

Virtual reality opens new perspectives in oro-facial rehabilitation. It allows the creation of motivating immersive environments and real-time visualization of oro-facial movements. This technology facilitates gestural learning and improves body awareness.
Electromyographic biofeedback quantifies oro-facial muscle activity and guides motor training. This objective approach allows for precise control of contraction intensity and prevents pathological compensations.
7. Progress Evaluation and Success Criteria
Evaluating therapeutic progress requires objective tools that are sensitive to change and clinically relevant. This measurement guides therapeutic adaptations, motivates the patient, and justifies the continuation or cessation of rehabilitation.
Quantitative and Qualitative Indicators
Quantitative indicators include gestural accuracy (success percentage), execution speed (reaction time and motor time), range of motion (degrees or millimeters), and endurance (number of repetitions before fatigue). These objective measures allow for precise longitudinal tracking.
Qualitative indicators assess gestural fluidity, naturalness of movements, motor economy, and functional integration. This subjective yet structured analysis complements quantitative evaluation and guides priority therapeutic objectives.
Therapeutic Success Criteria:
- Improvement ≥ 20% in standardized assessment scores
- Generalization to daily functional activities
- Maintenance of gains at 3 months post-therapy
- Patient/family satisfaction ≥ 8/10
- Significant reduction in pathological compensations
Validated Measurement Tools
Validated measurement scales ensure the reliability and comparability of assessments. They include standardized tests, quality of life questionnaires, and behavioral observation grids. The choice of tools depends on the patient's age, pathology, and therapeutic objectives.
The integration of automated measurement technologies (mobile applications, motion sensors) facilitates data collection and increases the frequency of assessment. This longitudinal approach improves diagnostic and therapeutic accuracy.
8. Interdisciplinary Integration and Interprofessional Collaboration
The rehabilitation of oro-facial praxia is part of an interdisciplinary approach involving speech therapists, physiotherapists, occupational therapists, neuropsychologists, and specialist doctors. This collaboration optimizes overall care and prevents therapeutic inconsistencies.
Specific Roles and Skills
The speech therapist coordinates the assessment and rehabilitation of language and swallowing aspects. The physiotherapist works on general motor skills and cervico-cephalic posture. The occupational therapist optimizes functional integration and daily autonomy. The neuropsychologist evaluates associated cognitive functions.
This distribution of roles requires regular communication, shared objectives, and common assessment tools. The use of collaborative digital platforms facilitates exchanges and improves therapeutic coordination.
The establishment of a structured interdisciplinary protocol significantly improves therapeutic outcomes. This coordinated approach allows for comprehensive and coherent patient care.
1. Initial multidisciplinary assessment
2. Definition of common goals
3. Coordinated therapeutic planning
4. Regular joint evaluations
5. Collaborative adaptation of the therapeutic project
9. Developmental Considerations and Pediatric Adaptations
Pediatric rehabilitation of oro-facial praxies requires specific adaptations considering the child's neuromotor, cognitive, and emotional development. The therapeutic approach must be playful, progressive, and respectful of the individual developmental pace.
Developmental Specificities
The development of oro-facial praxies follows a precise timeline, from birth to adolescence. Primitive reflexes gradually give way to voluntary movements, with complete maturation by 8-10 years. This developmental knowledge guides the establishment of realistic and adapted goals.
The child's limited attentional capacities impose short (15-20 minutes), frequent, and varied sessions. The use of visual supports, games, and rewards maintains engagement and facilitates motor learning.
🎈 Specialized Playful Approach
DYNSEO develops specific pediatric modules in COCO THINKS and COCO MOVES, integrating endearing characters, interactive stories, and challenges adapted to each age group. This natural gamification transforms rehabilitation into a moment of shared enjoyment.
Parental and Environmental Involvement
Parental involvement is a major predictive factor for therapeutic success in pediatrics. Parents become co-therapists, ensuring the continuity of exercises at home and reinforcing learning in a natural context.
Parental training includes teaching exercises, recognizing progress, managing difficulties, and adapting daily activities. This ecological approach optimizes the generalization of skills and prevents regressions.
10. Management of Associated Disorders and Comorbidities
Oro-facial praxic disorders are often accompanied by comorbidities requiring integrated management. These associated disorders include attentional difficulties, sensory disorders, behavioral problems, and cognitive deficits.
Attentional Disorders and Praxies
Attentional disorders compromise praxic learning by limiting concentration, task persistence, and gesture memorization. The therapeutic adaptation includes reducing session duration, increasing frequency, using motivating supports, and integrating regular breaks.
The use of interactive digital tools like COCO THINKS and COCO MOVES naturally captures the child's attention and maintains their engagement over time. The integrated reward mechanisms enhance intrinsic motivation.
The integration of relaxation exercises, controlled breathing, and mindfulness improves attentional capacities and optimizes the effectiveness of praxic rehabilitation. These techniques prepare the child for motor learning.
Hypersensitivities and Sensory Defenses
Oro-facial hypersensitivities complicate praxic rehabilitation by causing avoidance reactions, nausea, or defensive behaviors. Gradual desensitization, using varied textures, moderate temperatures, and graded stimulations, helps overcome these difficulties.
The therapeutic approach respects the individual tolerance threshold and progresses in successive stages. The use of relaxation and distraction techniques facilitates the acceptance of sensory stimulations necessary for rehabilitation.
11. Prevention and Oro-Facial Hygiene Recommendations
Prevention of oro-facial praxic disorders begins in early childhood by promoting good dietary, postural, and behavioral habits. This preventive approach reduces the incidence of dysfunctions and optimizes natural motor development.
Dietary Habits and Praxic Development
Early and gradual dietary diversification naturally stimulates oro-facial praxies by offering varied textures, consistencies, and flavors. This ecological stimulation promotes harmonious motor and sensory development.
Avoiding harmful habits (prolonged thumb sucking, excessive use of bottles or pacifiers) prevents the establishment of dento-skeletal deformities and motor dysfunctions. Early parental education is a major preventive issue.
Preventive Recommendations:
- Progressive dietary diversification starting at 4-6 months
- Limitation of pacifier use after 12 months
- Encouragement of bilateral chewing
- Prevention of mouth breathing
- Stimulation of babbling and vocal games
- Preventive consultation in case of risk factors
Early Detection and Warning Signs
Early detection of oro-facial praxic difficulties allows for optimal therapeutic intervention. Warning signs include delays in food acquisition, persistent articulation difficulties, swallowing disorders, and facial asymmetries.
Training of frontline professionals (pediatricians, nursery nurses, teachers) to recognize these signs improves early screening and facilitates specialized therapeutic orientation.
Contemporary research shows that oro-facial praxia exercises alone are not sufficient to improve articulation, as speech movements differ from non-verbal movements. However, they provide excellent therapeutic preparation by developing body awareness, motor coordination, and gestural dissociation. In certain specific pathologies (verbal dyspraxia, dysarthria, facial paralysis), they are an integral part of the rehabilitation protocol. Optimal effectiveness is achieved by combining praxic exercises and direct articulatory work on target phonemes.
Imitation games and facial expressions can start as early as 18-24 months in a playful and spontaneous manner. Structured exercises become feasible around 3-4 years old, when the child can understand and follow simple instructions. The approach should be adapted to the developmental level: sensory and food games for toddlers, directed but playful exercises for preschool children, more formal protocols for school-aged children. The use of applications like COCO THINKS and COCO MOVES facilitates children's engagement from the age of 5 due to their playful and interactive nature.
Research shows that short but frequent practice is more effective than a long weekly session. We recommend 10-15 minutes, 3-4 times a day for children, and 15-20 minutes, 2-3 times a day for adults. This distribution respects attention capacities, avoids muscle fatigue, and optimizes neuroplasticity. Integrating into daily routines (before meals, after brushing teeth) facilitates adherence. Monitoring with digital tools allows for adjusting frequency according to the patient's progress and motivation.
Oro-facial hypersensitivity requires a gradual and respectful desensitization approach. Start with external stimulations (around the mouth) before addressing the inside of the mouth. Use pleasant textures (soft brushes, silky fabrics), neutral temperatures, and light pressures. Self-stimulation (the patient controls it themselves) is better tolerated than passive stimulations. Integrate relaxation techniques, deep breathing, and distraction. Progression should be very gradual, respecting the individual pace. The use of enjoyable foods can facilitate acceptance of stimulations.
Digital applications like COCO THINKS and COCO MOVES are a valuable complement but do not replace the clinical expertise of the speech therapist. They offer unique advantages: daily autonomous practice, immediate feedback, personalized progression, motivation enhanced by gamification. However, clinical evaluation, fine therapeutic adaptation, management of specific difficulties, and human support remain irreplaceable. The optimal approach combines professional supervision and the use of digital tools, creating maximum therapeutic synergy.
