This paper reports the construction of gross motor development curves for children and youth with cerebral palsy (CP) in order to assess whether function is lost during adolescence. We followed children previously enrolled in a prospective longitudinal cohort study for an additional 4 years, as they entered adolescence and young adulthood. The resulting(More)
BACKGROUND The use of measurement tools is an essential part of good evidence-based practice; however, physiotherapists (PTs) are not always confident when selecting, administering, and interpreting these tools. The purpose of this study was to evaluate the impact of a multifaceted knowledge translation intervention, using PTs as knowledge brokers (KBs) to(More)
OBJECTIVES To describe the Rasch analysis of the Gross Motor Function Measure (GMFM-88) and to demonstrate how the assumptions of unidimensionality, sample-free measurement, and test-free measurement were validated to create an interval level measure. DESIGN Cross-sectional and longitudinal (12-mo) data from a prospective study of motor development in(More)
AIM To develop an algorithmic approach to identify item sets of the 66-item version of the Gross Motor Function Measure (GMFM-66) to be administered to individual children, and to examine the validity of the algorithm for obtaining a GMFM-66 score. METHOD An algorithmic approach was used to identify item sets of the GMFM-66 (GMFM-66-IS) using data from 95(More)
AIM To explore associations between clinical variables and decline in motor capacity in adolescents with cerebral palsy (CP). METHOD Participants included 76 males and 59 females, whose mean age at the beginning of the study was 14 years 6 months (SD 2.4, range 11.6-17.9); 51 at Gross Motor Function Classification System (GMFCS) level III, 47 at level IV,(More)
AIM The aim of this study was to compare the accuracy of two abbreviated approaches for estimating Gross Motor Function Measure 66 (GMFM-66) scores against the full GMFM-66 and to explore their strengths and limitations. METHOD An existing dataset (n=224) comprising children aged 1 to 13 years (mean age 6y 11mo, SD 4y 6mo; 132 males, 92 females) with(More)
OBJECTIVE To test the effect of personal and environmental factors on children's participation across 3 different settings (home, school, community); to ascertain the interrelations between these factors; and to propose and test 3 models, 1 for each setting, using structural equation modeling. DESIGN Survey, cross-sectional study, and model testing. (More)
PURPOSE To examine geographical variation in the leisure participation of children/youth with cerebral palsy (CP), using Children's Assessment of Participation and Enjoyment (CAPE) data from Australia, Canada (Ontario and Quebec) and the U.S. METHOD Data from 1076 children/youth ages 6-20 years with CP were included. Analyses examined CAPE diversity(More)
AIMS To describe the focus of therapy practices in occupational and physical therapy for school-aged children with cerebral palsy, and better understand whether it is congruent with recommended practices. METHODS A Canada-wide Web-based survey was completed by 62 occupational and 61 physical therapists to identify problems, assessments, and treatment(More)
The Ease of Caregiving for Children is a parent-completed measure of how difficult it is for them to safely help their children participate in activities of daily living. The objectives of this study were to determine the internal consistency, test–retest reliability, and construct validity (known groups methods) of the Ease of Caregiving for Children and(More)
