Neurosensorimotor Reflex Integration in Autism Spectrum Disorder: A Case Report

Abstract

Background: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social communication, behavioral regulation, sensory processing, and adaptive functioning. Persistent primitive reflexes and sensorimotor integration difficulties have been reported in some children with ASD and may contribute to functional limitations.
Objective: To evaluate the clinical outcomes of Neurosensorimotor Reflex Integration (NSMRI) on autism severity, primitive reflex integration, and sensory responsiveness in a child with ASD.
Methods: This single case report involved an 8-year-old boy diagnosed with ASD. NSMRI was administered twice weekly for three weeks, resulting in six treatment sessions. Outcomes were evaluated using the Childhood Autism Rating Scale (CARS), Children’s Primitive Reflex Integration Measurement Scale (CPRIMS), and structured clinical observation. Data were analyzed descriptively by comparing pre- and post-intervention findings.
Results: Following intervention, the CARS score decreased from 50 to 39, representing a reduction of 22.0%, while the CPRIMS score decreased from 12 to 9, representing a reduction of 25.0%. Clinical observations indicated improvements in eye contact, compliance with simple instructions, emotional regulation, attention during activities, cooperation throughout therapy sessions, and tolerance to tactile stimulation. Despite these improvements, the participant remained within the severe ASD category. No adverse events were reported during the intervention period.
Conclusion: NSMRI may provide potential benefits as a complementary physiotherapy intervention for improving primitive reflex integration, sensory responsiveness, and behavioral regulation in children with ASD. However, findings should be interpreted cautiously because they are derived from a single case without long-term follow-up.
