ABSTRACT
Background: Cerebral palsy (CP) is a neurodevelopmental disorder characterized by impaired motor control, coordination deficits, and functional limitations. Bilateral coordination skills are essential for participation in daily activities, yet their reliable measurement remains challenging. The Bruininks–Oseretsky Test of Motor Proficiency, Second Edition (BOT-2) and the Developmental Coordination Disorder Questionnaire (DCDQ) are commonly used to evaluate motor skills. However, the minimal detectable change (MDC) and minimal clinically important difference (MCID) for BOT-2 bilateral coordination subtest in children with CP remain underexplored.
Objective: To establish the MDC and MCID for the BOT-2 bilateral coordination subtest in children with CP and to compare them with DCDQ values.
Methods: This cross-sectional study involved 78 children with CP (mean age 10.35 ± 2.73 years; GMFCS Levels I–II) recruited from special schools. Participants underwent the BOT-2 bilateral coordination subtest and DCDQ at baseline, one week, and four weeks. Reliability was analyzed using intraclass correlation coefficients (ICC). Standard error of measurement (SEM), MDC at 95% confidence (MDC95), and MCID were calculated using distribution- and anchor-based approaches.
Results: The BOT-2 bilateral coordination subtest showed excellent reliability (ICC = 0.99, 95% CI: 0.98–0.99). SEM was 0.30, yielding an MDC95 of 0.84. The MCID, derived using anchor-based methods, was 1.92. In comparison, the DCDQ demonstrated an SEM of 0.97, MDC95 of 2.69, and distribution-based MCID of 2.31. Standardized response mean was higher for BOT-2 (0.80) than for DCDQ (0.21), indicating superior responsiveness.
Conclusion: The BOT-2 bilateral coordination subtest is a reliable and sensitive tool for detecting meaningful improvements in children with CP. A change of ≥1.92 points represent clinically significant progress, whereas DCDQ complements BOT-2 by capturing parent-perceived outcomes. Together, they offer a robust framework for outcome evaluation in pediatric neurorehabilitation.
