Background. Evaluation of the result of functional prosthetics in patients with different upper limb defects is a topical problem of modern prosthetics. Providing patients with non-functional hand stumps with functional prostheses is not wide-scale and refers to atypical and experimental prosthetics. While new functional prosthetic hands appear, there is no algorithm for evaluating the results of prosthetics. Aim. This study aimed to evaluate the result of functional prosthetics in children with congenital defects of the hand and fingers by active prostheses. Materials and methods. We observed 67 children with congenital hand defects, of which 22 were included in the experimental prosthetics group. Bench test station was used for an objective assessment of the residual function of the hand. The booth imitated the tasks of an international competition for the users of Cybathlon rehabilitation equipment and allowed users to perform a series of tests, for each of which a certain number of evaluation points were awarded. Samples at the stand were supplemented with a subjective assessment of the function of the hand using the DASH questionnaire validated in Russia. Results. The best subjective assessment of the supply of an active prosthetic hand was determined in the patients with underdeveloped hand similar to the truncation of the hand proximal to the metacarpophalangeal joints. The lowest functionality score of the active prosthetic hand was obtained in cases of ectrodactyly and hypoplasia of 1–5 fingers, which was associated with a high residual functionality of the hand. Conclusions. In addition to training functions, the developed bench test station serves a diagnostic function as it evaluates the results of functional prosthetics in patients with upper limb defects in different levels, including defects on the hand and fingers. The results of the study on the station correlate with the results of the DASH questionnaire.
