We report on a unilateral transradial amputee who used a bebionic hand which is a myoelectric prosthesis capable of multiple grasp functions. Intensive training was carried out for the application of the bebionic hand considering its characteristics, resulting in the number of practical grasp functions increasing from three to five. The patient was able to perform bilateral actions, and function became easier, with the proficiency level on the Myoelectric Prosthetic Hand Skill Assessment scale improving from 72.6% to 87.3%. Furthermore, on the Japanese version of the Michigan Hand Outcome Questionnaire, the ADL score on the affected side improved from 40 to 65 points, and the bilateral action score rose from 53 to 75 points. The most used grasping function was thumb abduction with the column of the thumb. These results indicate that the bebionic hand could be a practical compensatory measure.
