Functioning and activity outcomes of the Akwenda Intervention Program for children and young adults with cerebral palsy in Uganda: A cluster-randomized trial.

Abstract

Aim: To evaluate the efficacy of the Akwenda Intervention Program on motor, self-care, and social function of children and young people with cerebral palsy (CP).

Method: This was a cluster-randomized, controlled, single-blinded, intervention study of 100 participants with CP (2-23 years; 52 males) in rural eastern Uganda. Half were allocated to the intervention program, the remainder served as waitlist controls. Gross Motor Function Measure-66 (GMFM-66) and the Ugandan version of Pediatric Evaluation of Disability Inventory (PEDI-UG) were collected before group allocation and after intervention. General linear models and t-tests were used to compare changes within and between groups. Cohen's d estimated the effect size of group differences. Change scores were evaluated by age and mobility subgroups.

Results: Significant group by time interactions were found for GMFM-66 (p =0.003) and PEDI-UG outcomes (p <0.001), except mobility, with the intervention group demonstrating greater changes. Both groups increased their scores on the GMFM-66 and child PEDI-UG, while only the intervention group had significant increases in caregiver assistance scores and across all age and mobility subgroups. Cohen's d showed large effect sizes (d >0.8) of differences for PEDI-UG outcomes except mobility.

Interpretation: The Akwenda Intervention Program had a large positive impact on functioning and activity across age and mobility levels.
