Infant walkers and cerebral palsy

Area of Science:

• Pediatric neurology
• Developmental pediatrics
• Orthopedic rehabilitation

Background:

• Early intervention is crucial for infants diagnosed with spastic cerebral palsy (CP).
• Developmental milestones include the fading of primitive reflexes and the emergence of protective responses and equilibrium reactions.
• Standard infant walkers are commonly used for entertainment but may impact motor development.

Observation:

• A 1-year-old infant with early-stage spastic cerebral palsy was observed using an infant walker.
• The walker use was noted to elicit a positive support reflex, a primitive reflex typically diminishing within the first year of life.
• The infant's ability to practice developing equilibrium reactions and protective responses was impeded by walker use.

Findings:

• Infant walker use perpetuated a primitive reflex (positive support reflex) in an infant with spastic cerebral palsy.
• The walker prevented the infant from developing crucial equilibrium reactions and protective responses.
• Specific positions in the walker contributed to common adverse sequelae of spastic cerebral palsy, including heel cord contractures, hip subluxations/dislocations, and upper extremity pronation contractures.

Implications:

• The use of infant walkers may be detrimental for infants with spastic cerebral palsy, potentially exacerbating motor and orthopedic issues.
• Clinical recommendations should consider the impact of assistive devices on reflex development and motor learning in infants with CP.
• Further research is warranted to explore safer alternatives and therapeutic strategies for supporting motor development in infants with cerebral palsy.
