Summary
The POSNA questionnaire correlates with gait analysis in children with cerebral palsy (CP). The Log normalcy index (NI) predicts POSNA scores, offering a comprehensive assessment of function.
Area of Science:
- Pediatric Orthopedics
- Rehabilitation Medicine
- Biomechanical Engineering
Background:
- Cerebral palsy (CP) presents significant challenges in musculoskeletal function and mobility.
- Accurate assessment of functional health in pediatric CP is crucial for effective treatment planning and outcome evaluation.
Observation:
- This study investigated the correlation between the Pediatric Outcomes Data Collection Instrument (POSNA) Musculoskeletal Functional Health Questionnaire and computerized gait analysis in 63 children with spastic CP.
- Data included POSNA scales, gait parameters (Log normalcy index [NI], energy expenditure [EE]), and the Gillette Functional Assessment Questionnaire (FAQ).
Findings:
- The Log normalcy index (NI) was identified as a significant predictor of the POSNA Global Function and Comfort scale.
- POSNA scales demonstrated the ability to differentiate between various topographical types of cerebral palsy (hemiplegia, diplegia, quadriplegia, triplegia).
- Energy expenditure (EE) did not significantly contribute to predicting POSNA scores.
Implications:
- The POSNA scale is a valid and clinically useful tool for assessing children with CP.
- Integrating POSNA with gait analysis parameters like NI, EE, and FAQ provides a more comprehensive evaluation of functional changes in pediatric CP patients.
- This combined approach can enhance the appraisal of treatment effectiveness and patient progress.
