Gross Motor Function Measure (GMFM-66 and GMFM-88) User's Manual

The Gross Motor Function Measure (GMFM) is the leading standardized tool for evaluating gross motor abilities in children with cerebral palsy. Recognized internationally as the standard outcome measure, it quantifies changes in motor function over time and assesses the effectiveness of therapeutic interventions. This edition builds on prior versions by integrating an updated scoring program and new methods for abbreviated scoring, alongside enhanced guidance for clinical and research applications.

Key Features:

• Uses the updated GMFM scoring software (GMAE-2) for accurate assessment.
• Provides updated psychometric data for both GMFM-88 and GMFM-66 versions.
• Introduces two abbreviated scoring methods: GMFM-66 Item Sets (GMFM-66-IS) and GMFM-66 Basal & Ceiling (GMFM-66-B&C).
• Includes a new longitudinal case study demonstrating practical application and interpretation of GMFM scores.
• Offers a forward-looking extension to assess skill development in highly functional children with cerebral palsy.
• Introduces the Quality Function Measure to quantify changes in the quality of gross motor function.
• Serves physical therapists, pediatric clinicians, and researchers assessing motor function and evaluating intervention outcomes.
• Internationally validated and widely adopted as the standard tool for clinical and research use in cerebral palsy.
