Physical activity, quality of life and parenting stress in children with cerebral palsy.

ABSTRACT

BACKGROUND: Children with cerebral palsy (CP) are less physically active than their typically developing peers. The effects of decreased physical activity on children's quality of life (QOL) or caregiver's lives are not well understood. This study aimed to investigate the association between physical activity, QOL, and parenting stress in children with CP. METHODS: A prospective cross-sectional study was done in children with CP. Daily physical activity was measured over 7 days using an accelerometer (ActiGraph™). Caregivers completed the Child Health Questionnaire - Parent Form 50 and Parenting Stress Index - Short Form. Multiple regression analysis was used. RESULTS: In total, data from 65 children with Gross Motor Function Classification System (GMFCS) levels I-V, aged 4-13 years, were analyzed. Non-ambulatory (GMFCS IV-V) children had significantly lower activity counts and moderate to vigorous physical activity (MVPA) in comparison with ambulatory (GMFCS I-II) and marginally ambulatory (GMFCS III) children. The ambulatory group had better physical QOL than the non-ambulatory group. Caregivers of the non-ambulatory or marginally ambulatory children with CP reported higher parenting stress levels than those of the ambulatory group. Time spent in MVPA and activity counts were positively associated with physical QOL in children with CP. Low activity counts and low amounts of MVPA of children with CP were significant predictors of high parenting stress. CONCLUSIONS: Physical activity in children with CP is associated with children's QOL and parenting stress. These results suggest that clinicians should conduct physical activity assessment and counseling to promote physical activity.
