Abstract
Background
Manual functions affect more than a half of children with Cerebral palsy (CP). Asymmetric involvement of hands may also affect unilateral and bilateral activities of daily life. The Bimanual Fine Motor Function version 2.0 (BFMF-2.0) is a unique functional classification that categorizes the capacity of each hand (what the child can do) during bimanual functions.
Purpose
The aim of this study was to investigate the validity and reliability of the Turkish version of the BFMF-2.0 in children with CP.
Study Design
Clinical measurement and cross-sectional study.
Methods
The study included 91 children with CP (56 girls, mean age; 7.41 ± 4.23 years [4–18 years]) and their parents. The Manual Ability Classification System (MACS), the Quality of Upper Extremity Skills Test (QUEST), and the Box and Block Test (BBT) were used for construct and concurrent validity. Experienced/inexperienced therapists and parents classified fine motor capacities of the children via live or video-based observation to assess inter-rater reliability. Three weeks later, the children were reclassified for intra-rater reliability.
Results
The Turkish version of the BFMF-2.0 classification was strongly correlated with the MACS (rho = −0.88, p < 0.001), the QUEST (rho = 0.80, p < 0.001), and the BBT (rho = −0.77, p < 0.001). The inter-rater reliability scores were weak to excellent between the parents and the therapists (via live observation, κw = 0.57) and also between experienced/inexperienced therapists (via live or video-based observation, κw = 0.66–0.79). Intra-rater reliability scores were good to excellent (Intraclass Correlation Coefficient [ICC] = 0.87–0.95).
Conclusions
The Turkish version of the BFMF-2.0 classification is valid and reliable and could be applied by experienced and inexperienced therapists via live or video-based observation and by parents via live observation.
