Spanish-Language Cross-Cultural Validation of the Bimanual Fine Motor Function Classification System, BFMF 2

Introduction: Independent performance in infantile cerebral palsy is affected in daily life by the alteration in fine motor function and gross motor function. The function of the hand, expressed by the fine motor function, is essential to manipulate objects in daily life. The objective of this study was to translate and transculturally validate the bimanual fine motor function classification system, BFMF 2 for the Spanish population, as an instrument for the classification of bimanual fine motor function in children aged 3 to 18 years diagnosed with infantile cerebral palsy.

Material and Methods: The BFMF 2 consists of 5 levels of fine manual skill classification. For the execution of the Spanish version, a specific methodology of translation and back translation was used, reviewed by a group of experts in the upper extremity and approval of the Spanish version by the authors.

Results: the 5 levels of the scale were considered equivalent with the original version, being 100% literal, which gives a reliability of use at the scale for the Spanish population.

Conclusion: Having the Spanish version of this bimanual fine motor function classification system for infant cerebral palsy in the school stage allows the functioning of both hands to be defined in a more exhaustive way

Key words: Infantile cerebral palsy; Bimanual fine motor function; Transcultural adaptation
