Abstract

Recently, several multi-grip myoelectric prosthetic hands have become available in clinical practice in Japan. However, the indications for these novel myoelectric hands are still unclear. Here we report the experience of training and evaluation of two types of myoelectric prostheses, a traditional myoelectric hand (Ottobock Healthcare Products GmbH, myobock system) and a multi-grip myoelectric prosthetic hand, for a male with unilateral transradial amputation. Both prosthetic trainings have been completed successfully, and the multi-grip myoelectric prosthetic hand has been superior to the traditional myoelectric hand in various activities of daily living (ADLs) and vocational evaluations. Work efficiency was much better in the multi-grip myoelectric prosthetic hand than in traditional myoelectric hand in his workplace. As a result, the multi-grip myoelectric prosthetic hand was prescribed, and he reintegrated into a full-time job as a salesperson. For appropriate prescription of upper limb prosthesis, it is important to evaluate the need of each case in ADL and vocational activities, and to provide appropriate prosthetic training. The multi-grip myoelectric prosthetic hand could be a solution to improve work-related bimanual activities that are difficult to perform with the traditional myoelectric hand.
