ObjectivesTo assess aspects of hand function and manual capacity that influence bimanual performance in children with congenital hand differences (CHD), ranging from surgically corrected polydactyly or syndactyly to radial dysplasia. Secondly, to assess whether in this population the number of items on the Prosthetic Upper Extremity Functional Index (PUFI) can be reduced without losing information on bimanual performance.DesignCross-sectional designSettingUniversity Hospital's Outpatient clinicParticipants and Methods10-14 year-old children with CHD (N= 106)InterventionsNot applicableMain outcome measuresBimanual performance was evaluated with child self-reports on an adapted version of the PUFI, calculating ease of performance and actual use of the affected hand. Additionally, we assessed hand function and manual capacity.ResultsWe found that the median score on ease of performance was high and that, on average, children used their affected hand actively in 97% of all activities. Manual capacity of the non-dominant hand and lateral pinch strength of the dominant hand predict attainment of maximum PUFI scores. Non-maximum PUFI scores were predicted by opposition strength of the non-dominant hand and lateral pinch strength of the dominant hand. In addition, we found that in this patient group, only six items of the PUFI explain all variance in PUFI scores.ConclusionsChildren with a CHD generally have good bimanual performance and, on average, perform activities with active use of the affected hand. Therapy directed towards increasing manual capacity and finger muscle strength might assist to improve bimanual performance in children with CHD. Furthermore, we found that the number of items on the PUFI could be reduced from 38 to 6 items in children with CHD.
