Association between sensory processing and activity performance in children with cerebral palsy levels I-II on the gross motor function classification system

Background: Investigating the influence of sensory processing disorders on the level of function of children with cerebral palsy (CP) may help therapists identify specific impairments that impact activity and participation in these children. This may provide direction on selection of interventions to improve function and quality of life. Objectives: To investigate if sensory processing disorders in children with CP levels I and II on the Gross Motor Function Classification System (GMFCS) are associated with activity performance. Methods: Sensory processing and activity performance of 28 children with CP between 5 and 15 years (mean +/- standard deviation; 9.9 +/- 3.2 years) were evaluated using the Sensory Profile (SP) and Pediatric Evaluation of Disability Inventory (PEDI), respectively. Associations between the components of the SP and PEDI were assessed with Spearman correlation coefficients. Multiple linear regression analysis using backward stepwise method was used to determine the variables of sensory processing that are associated with activity performance on the PEDI. Results: The category of Behavioral Outcomes of Sensory Processing was the only variable associated with Functional Abilities in self-care and social function (r(2) = 0.30 and r(2) = 0.39, respectively) and Caregiver Assistance (r(2) = 0.36 and r(2) = 0.37, respectively), (p < 0.05). Conclusion: Sensory processing in children with CP levels I-II on the GMFCS is associated with their ability to perform daily living activities and in their social interaction with the environment.
