This paper presents an occupational therapy method for training children fitted with myoelectric prostheses. It is based upon a structured way of describing the accomplishments of a child fitted with a myoelectric prosthesis, called the Skill Index Ranking Scale (SIRS). By using the SIRS when designing the training session, the therapist can progressively increase the demands presented to the child. Furthermore, the SIRS facilitates for the therapist the documentation and communication of the childs ability with the myoelectric prosthesis.
