This research project in the field of augmentative aids for disabled people has as its main objective the assessment of motor routines training in persons with traumatic amputation on the distal side by a virtual trainer controlled by myoelectric signals. This research study is important, since it prepares the individual for the use of a real prosthesis and, thus, on a cognitive level, the virtual coach can create a system of self-representation, which is a point of convergence in the visual feedback system and is proprioceptive. In addition, because of the relationship of manipulationidentification- transformation of objects, the brain provides new ways of approaching prior tasks and the possibility of starting new ones. For this investigation, a system for capturing and recognizing myoelectric signals and the observational learning model proposed was designed, developed and validated.
