Tactile function in children with unilateral cerebral palsy compared to typically developing children

Area of Science:

• Neuroscience
• Developmental Pediatrics
• Rehabilitation Medicine

Background:

• Unilateral cerebral palsy (UCP) affects approximately 35% of children with cerebral palsy (CP), a leading childhood physical disability.
• While motor impairments are the primary focus, sensory deficits, particularly tactile impairments, are common in UCP.
• Limited research has comprehensively assessed tactile function in children with UCP.

Purpose of the Study:

• To comprehensively characterize tactile registration and perception abilities in children with UCP.
• To compare tactile performance between children with UCP and typically developing children (TDC).
• To identify the prevalence and nature of tactile deficits in children with UCP.

Main Methods:

• Fifty-two children with UCP and 34 TDC were evaluated using a battery of tactile assessments.
• Tactile registration was assessed using Semmes Weinstein Monofilaments.
• Tactile perception was evaluated through tests including single-point localization, double simultaneous, two-point discrimination, stereognosis, and texture perception.

Main Results:

• Children with UCP demonstrated significantly poorer performance with their impaired hand compared to their unimpaired hand (p < 0.005).
• Both hands of children with UCP performed worse than the hands of TDC (p = 0.037–< 0.001).
• Forty percent of children with UCP had deficits in both tactile registration and perception, 37% had only perception deficits, and 23% had no tactile deficits. A larger tactile registration deficit correlated with poorer tactile perception (r = 0.568–0.670; p < 0.001).

Conclusions:

• The majority of children with UCP exhibit impaired tactile perception, with over a third also having impaired tactile registration.
• Tactile dysfunction in UCP is prevalent and may significantly contribute to overall functional limitations.
• Addressing tactile impairments through targeted interventions could potentially improve functional outcomes and motor abilities in children with UCP.
