A new five-level system standardizes gross motor function classification for children with cerebral palsy (CP). This reliable system, developed by experts, aids clinical practice, research, and teaching for CP assessment.

Area of Science:

  • Pediatrics
  • Neurology
  • Rehabilitation Medicine

Background:

  • Cerebral palsy (CP) affects children's motor function.
  • A standardized classification system for gross motor function in CP is needed.
  • Existing systems lack comprehensive standardization for clinical and research applications.

Purpose of the Study:

  • To develop and validate a standardized five-level gross motor function classification system for children with cerebral palsy.
  • To establish a reliable and applicable system for diverse professional use.

Main Methods:

  • Utilized nominal group process and Delphi survey consensus methods.
  • Involved 48 experts including physical therapists, occupational therapists, and developmental pediatricians specializing in CP.

  • Assessed content validity and interrater reliability.

    • Main Results:

    • Achieved expert consensus on the five-level classification system.
    • Demonstrated good interrater reliability: kappa = 0.55 (children < 2 years) and kappa = 0.75 (children 2-12 years).
    • The system showed applicability for clinical practice, research, teaching, and administration.

    Conclusions:

    • The developed five-level system provides a standardized approach to classifying gross motor function in children with CP.
    • The system is reliable and has broad applications across professional domains.
    • This classification system addresses a critical need in the field of cerebral palsy.
