Application of the Gross Motor Function Measure-66 (GMFM-66) in Dutch clinical practice: a survey study

Background The Gross Motor Function Measure-66 (GMFM-66) is an observational clinical measure designed to evaluate gross motor function in children with Cerebral Palsy (CP). It is a shortened version of the GMFM-88. A free computer program, the Gross Motor Ability Estimator (GMAE), is required to calculate the interval level total score of the GMFM-66. The aim of this study was to explore pediatric physiotherapists’ experiences with the GMFM-66 and application of the measure in Dutch clinical practice.
