Background: Autism Spectrum Disorder (ASD) is characterized by social communication deficits, restricted/repetitive behaviors, sensory processing atypicalities, and impaired adaptive functioning. Neuropsychomotor Therapy of Early Development (TNPEE) integrates motor, cognitive, and socio-emotional domains, promoting functional skills, while Therapy in Aquatic Motor Activities (TAMA) targets motor and sensory engagement. This multicenter, 18-month study compared TNPEE, TAMA, and their combination, hypothesizing that TNPEE would drive core symptom and adaptive improvements, with TAMA providing complementary benefits. Methods: Seventy-seven children with Autism Spectrum Disorder (31.6% females) were recruited from four Italian centers (Palermo, Perugia, Sarno, Messina) and allocated to three groups: TAMA only, TNPEE combined with TAMA, and TNPEE only. Assessments included the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2), the Childhood Autism Rating Scale, Second Edition (CARS-2), Vineland Adaptive Behavior Scales, Sensory Processing Measure and HAARS at baseline, 6, 12, and 18 months. Results: By 18 months, children receiving TNPEE, alone or combined with TAMA, exhibited significant reductions in autism severity, significant improvements in adaptive functioning, and enhanced sensory processing. In contrast, the TAMA-only group demonstrated improvements in aquatic competence (HAARS) but no statistically significant changes in ASD severity or adaptive functioning. Conclusions: TNPEE was the intervention most consistently associated with improvements in ASD severity, adaptive functioning, and sensory processing, whereas TAMA alone showed a more limited impact on broader developmental outcomes.
