Les réflexes archaïques et la paralysie cérébrale : une approche sensori motrice de cette rééducation
When discussing cerebral palsy, conversations often center on visible physical limitations. However, underlying each movement is unsuspected complexity—a network of sensorimotor patterns dependent on archaic reflex maturation. Rather than resolved in infancy, this reflex-based motor control persists in individuals with cerebral palsy, affecting daily movement. This article explores how careful observation of these reflexes contributes to more precise rehabilitation for affected patients. We examine how understanding these reflexes, though not constituting a method themselves, provides a complementary pathway for sensorimotor integration, improving overall function in children and adults alike.
Comprendre le rôle des réflexes archaïques dans la paralysie cérébrale
Cerebral palsy—the primary motor disability cause in French children—affects approximately four newborns daily and impacts 17 million people globally. This neurological disorder, stemming from central nervous system lesions, manifests through variable motor, sensory, and cognitive difficulties. To better support patients, observing and understanding archaic reflexes offers an essential perspective, often overlooked yet particularly relevant for clarifying therapeutic choices and objectives. For more on sensorimotor approaches presented in training programs, visit the blog. Multiple archaic reflexes are discussed there, including the tonic labyrinthine reflex and Pérez reflex, frequently hyperactive in this population.
Qu'est-ce que les réflexes archaïques ?
Archaic reflexes don't constitute a method per se—they're simply reflexes developing during intrauterine periods, with activity disappearing for most during early infancy. In typically developing infants, these reflexes gradually fade through neurological maturation and voluntary motor development. The asymmetrical tonic neck reflex and Moro reflex, for instance, normally diminish around four months.
However, in children with cerebral palsy, these reflexes persist and may interfere with motor development. Extension patterns in infants often remain more active in these children, subsequently affecting other archaic reflex integration.
This reflex persistence disrupts acquisition of fundamental motor skills like grasping, balance, and walking.
Les atteintes motrices de la paralysie cérébrale
Cerebral palsy presents in various clinical forms: diplegia, quadriplegia, monoparesis, or tetraplegia. Presentations may be spastic, dystonic, ataxic, or mixed. A common element is frequently axial hypotonia coexisting with peripheral hypertonia.
Voluntary motor command disorders, coordination difficulties, and pareses are frequent. Over time, these anomalies produce muscle structural changes, contractility reduction, and strength decrease, creating significant functional and orthopedic consequences.
L'observation des réflexes archaïques pour adapter la rééducation
Une approche complémentaire, non exclusive
Observing archaic reflexes fits within comprehensive rehabilitation approaches. It doesn't replace other methods but complements them. Task-oriented or muscle-strengthening rehabilitation don't provide identical benefits as sensorimotor rehabilitation; these approaches must combine for optimized functional rehabilitation results. To explore training on these approaches, visit the formations page.
This integrative vision enables rehabilitation adaptation based on persistent motor patterns. For example, a child with non-integrated tonic labyrinthine reflex struggles dissociating head movements from trunk movements, directly influencing sitting, standing, and object-grasping abilities.
L'identification des schémas prioritaires
A major advantage of this approach involves identifying priority schemas. During therapeutic sessions offered, one priority schema receives focused work weekly. This method precisely targets blockages preventing child progression, whose maturation impacts multiple functional aspects.
For a three-month-old like Cassandra, presenting bilateral adductor spasms and cerebral lesions, work concentrates on "axis across three spatial planes" for postural tone regulation. This three-dimensional movement perspective helps integrate excessive extension schemas common in these children. Posterior chain lengthening contributes to archaic reflex activity regulation, but optimal relaxation of hyperactive extension patterns requires working across inclination and rotation planes.
Similarly, activating functional active spine straightening requires more than extension work alone (often deficient in these hypotonic children). Working across inclination and rotation planes facilitates hyperactive extension schema regulation AND functional spine extension. For better understanding this connection and distinctions between hyperactive extension schemas and functional spine extension, review these articles:

Des cas cliniques d'enfants atteint de paralysie cérébrale
Théo, 3 ans : intégrer l'hémicorps droit
Théo's case—a three-year-old with right hemiparesis—perfectly illustrates this approach's contribution. Despite previous quality care and multiple intensive sessions from different methods proving beneficial, Théo maintained his right hand constantly closed during walking with his right arm withdrawn.
Work concentrated on two priority schemas: asymmetrical tonic neck reflex and segmental rolling. Four-point positioning strengthening improved flexor-extensor muscle coactivation, while segmental rolling work promoted head, shoulder, and pelvis rotation coordination, encouraging scapular antepulsion and right hemipelvis anterior positioning.
Within one week, Théo maintained four-point position with both hands open, and his right hand opened during walking (though not running). Upon returning home, he opened a yogurt container independently for the first time—concrete evidence of right hemibody retro-positioning schema regulation. This postural adjustment consequently affected his distal tone regulation and standing balance.
I emphasize these conclusions reflect my result interpretation, embodying Bobath and Feldenkrais method fundamentals: both methods address proximal tone regulation affecting distal function.
Léa, 5 ans : dépasser les limitations posturales
Léa, a five-year-old with spastic quadriplegia, faced a major obstacle: inability to sit independently, her head systematically extending backward. Standing, her knees involuntarily flexed when viewing her feet, and four-point positioning remained impossible.
Tonic labyrinthine reflex integration became Léa's breakthrough point. This reflex linking head movements to trunk and limb movements prevented dissociating neck flexion from trunk and lower limb flexion.
In merely three days of targeted work, progress proved impressive: Léa maintained four-point positioning on a wheeled board, with neck extension and lower limb flexion. Three weeks post-session, Léa sat independently, improved lower limb alternation for more functional walking, and initiated four-point movement with ventral support. This schema maturation impacted her grasping, enabling upper limb lengthening without head extension.
L'adaptation pour les enfants atteints de polyhandicap
For Léandre, age two, with quadriplegia and severe intellectual disability, adaptation considered limited active participation capacity. Intervention relied more on tactile stimulation and sensory games.
Addressing head control—an unreached rehabilitation objective—archaic reflex observation identified hyperactive or hypoactive muscle groups and which sensory stimulation (tactile/visual/vestibular/auditory) maintains tone imbalances. Archaic reflex knowledge enables action across sensory AND motor planes, facilitating function maturation, even for children with greater limitations.
La rééducation sensori-motrice : un élément clé
A fundamental dimension involves sensorimotor integration. Rehabilitation work transcends purely motor aspects, incorporating sensory information processing.
L'impact sur le traitement sensoriel
Archaic reflex integration helps children process sensory information better. For instance, with hyperactive Pérez reflex, each vertebral column tactile stimulation triggers involuntary body extension. Working on this reflex, children learn dissociating tactile stimulation from stereotyped motor responses.
This approach benefits tactile or vestibular hypersensitive children. Regulating these reflexes enables more appropriate sensory information processing, reducing hyperreactivity limiting environmental interactions.
La régulation tonique proximale et distale
For children with hyperactive extension schemas, proximal tone maturation work assists distal tone regulation.
This clinical observation proves striking: children showing significant peripheral spasticity reduction following week-long extension schema work concentrated on axial regions. Their hands open more easily and feet are less gripped, despite work focusing mainly on proximal regions.
This approach acknowledges bidirectional tone influences: proximal-to-distal work isn't always necessary; the reverse sometimes functions. Distal work may also assist proximal maturation.

These practices integrate well into weekly child follow-ups or intensive rehabilitation sessions.
Les théories d'apprentissage moteur et leur intégration
Diversité des approches d'apprentissage
Sensorimotor rehabilitation fits broader motor learning theory frameworks.
Some theories include cognitive learning, particularly suited to adults and older children, where intellectual movement comprehension improves gestures. For infants or polyhandicapped children, other approaches gain priority, such as experiential learning, incorporating maturation and sensory information processing.
This cognitive learning, founded on "predictive" motor learning theory, benefits certain ages but remains complementary to more somatic experiential learning based on sensorimotor experience. Feldenkrais method theory entirely grounds itself in this more organic learning, independent of intellect but dependent on our brain's capacity, regardless of age, selecting sensorimotor schemas appearing most adjusted to various situations (without intellectual movement control).
This second learning type exists exclusively in infants and polyhandicapped children. Yet we tend forgetting it continues in older individuals. I'll write a forthcoming article better explaining different learning modes.
The rehabilitation founded on archaic reflex observation offers precious perspective in cerebral palsy children's care. Rather than miraculous methodology, it constitutes comprehensive, complementary approaches to other therapeutic techniques. Its effectiveness resides in sensorimotor priority schema targeting capacity, permitting sometimes astonishing functional breakthroughs, even in children previously benefiting from other intensive rehabilitation forms. By targeting sensorimotor priority schemas, significant progress remains possible, even in complex cases.
