OBJECTIVE: To examine the relation between walking performance and participation
in mobility-related habits of daily life in children with cerebral palsy (CP). To
date, walking outcomes in CP have been capacity-based (what a child does in
structured setting). Physical activity performance (what a child really does in
daily life) has been documented to affect the relation of capacity-based gross
motor measures and participation. DESIGN: Cross-sectional prospective cohort
study. SETTING: Regional pediatric specialty care centers. PARTICIPANTS: A cohort
of ambulatory children with CP (N=128; age, 2 to 9y; 41% girls; 49% having
hemiplegia) participated. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES:
Walking performance was quantified from a 5-day sample of accelerometry data.
Stride activity was summarized through the outcomes of the average number of
total strides per day (independent of intensity) and the average number of total
strides per day at >30 strides/min (marker of intensity). Mobility-based
participation was assessed by using the Assessment of Life Habits for Children
questionnaire categories of personal care, housing, mobility, and recreation.
Regression models were developed controlling for sex, age, cognition,
communication, pain, and body composition. RESULTS: The average number of total
strides per day was positively associated with the personal care, housing,
mobility, and recreation Assessment of Life Habits for Children questionnaire
categories (beta=.34-.41, P<.001). The average number of total strides per day at
>30 strides/min was associated with all categories (beta=.54-.60, P<.001).
CONCLUSIONS: Accelerometry-based walking activity performance is significantly
associated with levels of participation in mobility-based life habits for
ambulatory children with CP. Evaluation of other factors and the direction of the
relation within the International Classification of Functioning, Disability and
Health is warranted to inform rehabilitation strategies.
