The gait pattern classification system for children with spastic cerebral palsy (sCP) shows good validity. Refined rules and clinical phenotypes support its use in practice for better decision-making.

Area of Science:

  • Biomedical Engineering
  • Clinical Biomechanics
  • Pediatric Orthopedics

Background:

  • The "gait pattern classification system for children with spastic cerebral palsy" (GaP-CP) was developed to classify gait deviations in children with spastic cerebral palsy (sCP).
  • The system includes a novel "mild deviations" category, developed from a systematic review and expert consensus.
  • Validation of the GaP-CP's content and construct validity is crucial for its clinical utility.

Purpose of the Study:

  • To examine the content validity of the GaP-CP by comparing kinematic and kinetic data of children with sCP to typically developing children.
  • To assess the construct validity of the GaP-CP by analyzing differences between neighboring gait patterns and exploring pattern-specific clinical phenotypes.

Main Methods:

  • Non-parametric statistical comparisons were used to analyze kinematic (N=270) and kinetic (N=208) data from children with sCP and typically developing children (N=56).

  • Kruskal-Wallis and Mann-Whitney U tests were employed to differentiate between gait patterns and explore patient- and impairment-specific characteristics.
  • Analysis focused on identifying differences between adjacent gait patterns (construct validity) and all patterns (phenotype exploration).

    • Main Results:

    • The GaP-CP demonstrated good content validity, with most classification rules confirmed by patient data; apparent equinus was most prevalent.
    • Construct validity was supported by the system's ability to distinguish between neighboring gait deviations and identify pattern-specific phenotypes based on patient characteristics.
    • Clear differentiation of pattern-specific phenotypes based solely on impairment characteristics was not achieved.

    Conclusions:

    • The findings support the validity of the GaP-CP for classifying gait patterns in children with sCP.
    • Refined classification rules and precise terminology provide a clear path for clinical implementation.
    • The identified pattern-specific clinical phenotypes enhance the system's utility in clinical practice and aid in decision-making.
