The model may have utility for collaboration with families and community providers, determining goals for participation, and providing evidence-informed interventions.

Supporting children's adaptive behaviour, family ecology, and access to community recreational programmes may foster participation in family and recreational activities for young children with CP. Implications for Rehabilitation Participation in family and recreational activities for young children with CP is complex and influenced by child, family and environmental factors. Practitioners are encouraged to support children's adaptive behaviour and access to community programs and family relationships, involvement in community activities and expectations of their children. Optimizing gross motor function for children who have limitations in self-mobility may enhance their participation in family and recreational activities. For children with a good prognosis for walking, providing services perceived by parents to meet their children's needs may enhance children's enjoyment of participation.

AIM To explore the relationship between rehabilitation therapies and development in children with cerebral palsy (CP). METHODWe conducted a prospective, longitudinal study involving 656 children with CP (mean age [SD] 6y [2y 8mo] at study entry; 1y 6mo-11y 11mo; 287 females, 369 males), and their parents. Children were assessed two to five times over 2 years by therapists using standardized measures of balance and walking endurance. Parents completed questionnaires on demographics, rehabilitation therapies, and their children's performance in self-care and participation in recreation. Therapists and parents collaboratively classified children's Gross Motor Function Classification System (GMFCS) levels. We created longitudinal graphs for each GMFCS level, depicting change across time using centiles. Using multinomial models, we analyzed the relationship between therapies (amount, focus, family-centeredness, and the extent therapies met children's needs) and whether change in balance, walking endurance, and participation was 'more than' and 'less than' the reference of 'as expected'. RESULTSChildren were more likely to progress 'more than expected' when participating in recreation when therapies were family-centered, met children's needs, and focused on structured play/recreation. A focus on health and well-being was positively associated with participation and self-care. The amount of therapy did not predict outcomes.

AIM The aim of this study was to test a model of determinants of gross motor function of young children with cerebral palsy (CP).METHOD Four hundred and twenty-nine children with CP (242 males, 187 females; mean age 3y 2mo, SD 11mo) representing all levels of the Gross Motor Function Classification System (GMFCS) participated. Children in levels I to II and III to V were classified as Groups 1 and 2 respectively. Distribution of CP was quadriplegia, 44%; hemiplegia, 24%; diplegia, 23%; triplegia, 6%; and monoplegia, 2% (data not available for 1%). Impairment and motor function data were collected by reliable assessors; parents completed questionnaires on health conditions and adaptive behavior. Seven months later, parents were interviewed about family life and services received. One year after the study onset, motor function was re-evaluated. Analysis involved structural equation modeling. RESULTSThe well-fitting model explained 58% and 75% of the variance in motor function at study completion for Groups 1 and 2 respectively. Primary impairments (spasticity, quality of movement, postural stability, and distribution of involvement; b=0.52-0.68) and secondary impairments (strength, range of motion limitations, and reduced endurance; b=0.25-0.26) explained the most variance. Adaptive behavior was a significant determinant only for Group 2 (b=0.21) and participation in community programs was significant only in Group 1 (b=0.13).INTERPRETATION Motor function is supported by optimizing body structures and function for all children and enhancing adaptive behavior for children with greater motor challenges.Cerebral palsy (CP) is a complex condition resulting from damage to the immature brain with the primary features of movement limitations and impairments of postural control.

Supporting children's gross motor function, health and adaptive behaviour may optimize self-care participation.

Background Children with cerebral palsy (CP) frequently present with secondary impairments in spinal alignment and extremity range of motion, endurance for activity, and muscle strength. Creation of developmental trajectories for these impairments will help guide clinical decision-making. Objective For children in each level of the Gross Motor Function Classification System (GMFCS) this study aimed to: (1) create longitudinal developmental trajectories for range of motion (Spinal Alignment and Range of Motion Measures [SAROMM]), endurance (Early Activity Scale for Endurance [EASE]), and functional strength (Functional Strength Assessment [FSA]); and (2) develop age-specific reference percentiles and amount of change typical over 1 year for these outcomes. Design This study used a longitudinal cohort design. Methods Participants comprised 708 children with CP across GMFCS levels, aged 18 months up to the 12th birthday, and their families. In 2 to 5 assessments every 6 months over 2 years, trained therapists performed the SAROMM and FSA, and parents completed the EASE questionnaire. For children in each GMFCS level, longitudinal trajectories using linear and nonlinear mixed-effects models from all visits, and reference percentiles using quantile regression from the first, 12-month, and 24-month visits were created for each measure. Results Longitudinal trajectories and percentile graphs for SAROMM, FSA, and EASE were primarily linear, with different performance scores among GMFCS levels. There was much variability in both longitudinal trajectories and percentiles within GMFCS levels. Limitations Limitations included a convenience sample and varying numbers of participants assessed at each visit. Conclusions The longitudinal trajectories and percentile graphs have application for monitoring how children with CP are performing and changing over time compared with other children with CP. The resources presented allow therapists and families to collaboratively make decisions about intervention activities targeted to children's unique needs.

Purpose: The purposes of this study were to: 1) document longitudinal developmental trajectories in 6MWT distances and 2) develop age-specific reference percentiles for children across different Gross Motor Function Classification System (GMFCS) levels. Methods: 456 children with CP ages 3 to 12 years of age, GMFCS Levels I-III participated. Children's motor function was classified on the GMFCS, and children completed the 6MWT two to five times across 2 years. Nonlinear mixed effect models and quantile regression were used to analyze the data. Results: Longitudinal developmental trajectories demonstrated 6MWT distances increase with age followed by a tapering as children approach their functional limit relative to their GMFCS level. Reference percentile graphs were created to monitor change over time. Conclusions: The 6MWT longitudinal developmental trajectories, reference percentiles and interpretation of percentile change presented in this paper should assist collaborative and proactive intervention planning relative to functional walking capacity for children with CP.

This perspective article provides an example of a study planned using guidelines for comprehensive rehabilitation outcomes research, an approach that is believed to give service providers meaningful evidence to support practice. This line of investigation has been guided by the World Health Organization's International Classification of Functioning, Disability and Health. The short title of a study under way is Move & PLAY (Movement and Participation in Life Activities of Young Children). The article briefly describes the conceptual model, provides guidelines on how indicators and measures are selected, alludes to the details of selected measures, and describes processes of preparing for data collection, including obtaining ethics approval, preparing data collection booklets, training assessors and interviewers, and sampling. The aim of this investigation is to gain a better understanding of the multiple child, family, and service factors associated with changes in mobility, self-care, and play of preschool children with cerebral palsy as a result of using this research method. Comprehensive rehabilitation outcomes research holds promise in providing evidence that supports the complexities of planning rehabilitation services with clients with chronic conditions, such as children with cerebral palsy.
