Abstract:

Summary Introduction There are many instruments designed to evaluate motor function in children with cerebral palsy ( CP ) . The purpose of this study is to provide a Spanish version of the Gross Motor Function Measure ( GMFM ) from its original English version , which is the first step of its cross - cultural adaptation process to the Spanish population . Material and methods The GMFM is an observational measure designed to evaluate change in gross motor function over time in children with CP . It is composed of 88 items grouped into five functional dimensions . In order to produce the Spanish version has been used a methodology that involves several steps : translation/back - translation by six bilingual independent translators , committee review and pilot study with three specialists in Physical Medicine and Rehabilitation . Results Fifty - eight items ( 66 % ) had literal translation , being classified as literal items ; 30 items ( 34 % ) suffered syntactic modifications , being classified as similar items . After pre - testing study 3 items were modified because its wording was confusing . Conclusions The Spanish version of the GMFM was obtained , easy to use and well accepted in the daily clinical practice , successfully completed the first step of its crosscultural adaptation process to the Spanish population ; we must carry out its validation to complete this pro cess , after checking its clinimetrics characteristics of validity and reliability .
