The Bimanual Fine Motor Function (BFMF) is currently the principal classification of hand function recorded by the Surveillance of Cerebral Palsy in Europe (SCPE) register. The BFMF is used in a number of epidemiological studies, but has not yet been validated.
To examine aspects of construct and content validity of the BFMF.
Construct validity of the BFMF was assessed by comparison with the Manual Ability Classification System (MACS) using register-based data from 539 children born 1999-2003 (304 boys; 4-12 years). The high correlation with the MACS (Spearman's rho = 0.89, CI: 0.86-0.91, p<.001) supports construct validity of the BFMF. The content of the BFMF was appraised through literature review, and by using the ICF-CY as a framework to compare the BFMF and MACS. The items hold, grasp and manipulate were found to be relevant to describe increasingly advanced fine motor abilities in children with CP, but the description of the BFMF does not state whether it is a classification of fine motor capacity or performance.
Our results suggest that the BFMF may provide complementary information to the MACS regarding fine motor function and actual use of the hands, particularly if used as a classification of fine motor capacity.
双手精细运动功能（BFMF）目前是欧洲脑瘫监测（SCPE）登记册记录的手部功能的主要分类。BFMF被用于多项流行病学研究，但尚未得到验证。
检验BFMF的结构效度和内容效度。
通过与手动能力分类系统（MACS）比较，利用1999 - 2003年出生的539名儿童（304名男孩；4 - 12岁）的登记数据评估BFMF的结构效度。与MACS的高度相关性（斯皮尔曼等级相关系数rho = 0.89，置信区间：0.86 - 0.91，p <.001）支持了BFMF的结构效度。通过文献综述，并以国际功能、残疾和健康分类儿童版（ICF - CY）为框架比较BFMF和MACS来评估BFMF的内容。发现抓握、握持和操作项目与描述脑瘫儿童日益高级的精细运动能力相关，但BFMF的描述未说明它是精细运动能力还是表现的分类。
我们的结果表明，BFMF可能在精细运动功能和手部实际使用方面为MACS提供补充信息，特别是如果将其用作精细运动能力的分类时。
