Experimental: intervention group

Participants in this group receive individualized sensory integration therapy sessions once a week for 8 weeks, in addition to their routine physiotherapy program. Each session lasts approximately 45 minutes and is based on the core principles of sensory integration therapy. The intervention includes activities involving tactile, vestibular, proprioceptive, auditory, and visual stimuli, tailored to each child's sensory processing needs. Therapy is provided in a sensory-enriched and safe environment, and aims to promote adaptive responses, motor planning, self-regulation, and functional skills. Sessions are play-based and structured to support engagement and motivation.

No_intervention: control group

Participants in this group will not receive any sensory integration therapy during the 8-week study period. Instead, they will continue with their existing routine physiotherapy program, which may include general motor exercises, range of motion activities, and other standard therapeutic practices. No additional sensory-based interventions will be introduced. This group serves as a comparator to assess the effects of sensory integration therapy provided to the experimental group
