Gross Motor Function Measure (

The Gross Motor Function Measure (GMFM) has become the best evaluative measure of motor function designed for quantifying change in the gross motor abilities of children with cerebral palsy. The new version of the scoring programme has now been released, and includes two abbreviated methods of estimating GMFM-66 scores using the GMFM-66-Item sets and the GMFM-66-Basal & Ceiling.

The measure is very widely used internationally, and is now the standard outcome assessment tool. This new edition builds on the wide success of the first edition and:

• Is now based on an updated version of the GMFM scoring program (GMAE-2)
• Includes an update on the psychometric properties of the GMFM-88 and GMFM-66
• Covers development and validation of two abbreviated methods of estimating GMFM-66 scores using the GMFM-66 Item sets (GMFM-66-IS) and the GMFM-66-B&C (Basal and Ceiling)
• Includes a new longitudinal case illustration of the development, application and interpretation of the measure
• Presents a forward look to an upward extension of the GMFM to assess skill development in highly functional young people with cerebral palsy
• Presents a forward look to Quality Function Measure to quantify changes in quality of gross motor function

Readership

• Physical Therapists and other health professionals working with children, youth and adults with cerebral palsy
• Clinical and health services researchers as an outcome measure to assess the impact of numerous interventions that are proposed as methods of enhancing gross motor function in this population
• Any clinician who is assessing and describing current gross motor function and evaluating its change over time
• It serves the needs of clinical and health services researchers as an outcome measure to assess the impact of any of a host of interventions that are proposed as methods of enhancing gross motor function in this population.

Dianne J. Russell is Research and Knowledge Exchange Specialist with CanChild Centre for Childhood Disability Research.  She has been a health services researcher for over 20 years and a key individual in the development, evaluation and dissemination of clinical outcome measures such as the Gross Motor Function Measure (GMFM). Her current focus is on facilitating the use of research evidence in practice by engaging with research users throughout the research process and by making research results easily accessible in multiple formats to families, service providers, and policy decision-makers.
