Insights
Children with cerebral palsy (CP) show varying self-care development based on manual ability. Higher function (MACS I-III) improves self-care, while severe impairment (MACS V) leads to decline.
Area of Science:
- Pediatric rehabilitation
- Developmental pediatrics
- Neurology
Background:
- Cerebral palsy (CP) affects motor skills, impacting daily activities.
- Understanding self-care development is crucial for children with CP.
- Manual Ability Classification System (MACS) categorizes functional ability.
Purpose of the Study:
- To examine self-care development trajectories in children with CP.
- To analyze development across all Manual Ability Classification System (MACS) levels.
- To identify factors influencing self-care progression in pediatric CP.
Main Methods:
- Prospective longitudinal population-based study of 71 children with CP (2.5 to 12 years).
- Utilized Pediatric Evaluation of Disability Inventory (PEDI) and PEDI-Computer Adaptive Test (PEDI-CAT) for self-care assessment.
- Employed multilevel mixed-effects regression modelling to analyze age and MACS interaction.
Main Results:
- Children in MACS levels I-III demonstrated consistent self-care progress (0.48-0.72 change/year).
- MACS level IV showed a non-significant upward trend in self-care (0.42 change/year).
- Children in MACS level V experienced a significant decline in self-care (-0.65 change/year).
Conclusions:
- Self-care attainment by late childhood correlates with manual ability severity in CP.
- The study highlights potential limitations of PEDI-CAT at the lower functional end.
- Recommendations include adding items to PEDI-CAT to mitigate floor effects in CP self-care assessment.
Aim:
To investigate self-care developmental trajectories in children with cerebral palsy (CP) across all functional ability levels, according to Manual Ability Classification System (MACS) levels.
Method:
This was a prospective longitudinal population-based study of 71 children aged from 2 years 6 months to 12 years, with CP (47 [66%] males, 24 [34%] females). Pediatric Evaluation of Disability Inventory (PEDI) measures were taken at 2 years 6 months, 3, 4, and 5 years, and the PEDI - Computer Adaptive Test (PEDI-CAT) between 8 and 12 years. At 8 to 12 years, children were classified in MACS levels I (21; 30%), II (22; 31%), III (16; 23%), IV (6; 8%), and V (6; 8%). Longitudinal analysis of the PEDI Functional Skills Scale self-care and PEDI-CAT daily activities domains used the published linking equation, and multilevel mixed-effects regression modelling with interaction between age and MACS.
Results:
Between 5 and 12 years of age, children classified in MACS levels I to III continued to show progress in self-care development (PEDI-CAT scaled scores estimated change per year: I, 0.72; II, 0.49; III, 0.48). Children classified in MACS level IV showed an upward non-significant trend between 5 and 8 to 12 years (estimated change 0.42; 95% confidence interval [CI] -0.04 to 0.88). Children in MACS level V showed a decline in self-care (estimated change: -0.65; 95% CI -1.16 to -0.14).
Interpretation:
Self-care development attained by 8 to 12 years of age was related to the severity of manual ability impairment. Application of the linking equation from PEDI to PEDI-CAT is somewhat uncertain at the extreme lower end of the scale. Our study supports recommendations for items to be added to the PEDI-CAT to address floor effect.
