Assessment of Modified Toe-to-Palm Transfer

To the best of our knowledge a validated, widely-implemented, objective, tool to evaluate outcome of such procedures in children is yet to be established. However, to enable comparability of our results with those reported previously, we have used a modified version of the assessment tool developed by Percival et al. [13 (link), 14 (link)]. We also evaluated whether MTP transfer impacts on hand dominancy and assessed whether patients showed preference for using the hand that was operated on. The sensibility was examined and recorded in terms of having a two-point discriminatory capacity of < 5 mm.
We certify that all applicable institutional and governmental regulations concerning the ethical use of human volunteers were followed during this research. Informed written consent was obtained from all participants parents and the Ethical Committee of Tehran University of Medical Sciences approved this study. Parents of the children of whom pictures or videos are to be published have given their written consent. The study protocol conforms to the ethical guidelines of the 1975 Declaration of Helsinki.
The parents/guardians of the children provided informed written consent to participate. We obtained consent for publication from the parents/guardians of the children included in the study to publish the photos of participants.
