In this research a system of virtual training for transradial myoelectric prosthesis was developed by using surface electrodes placed on the brachioradialis muscle to control the movements of apprehension and prehension and the supinator muscle to control the rotational movement. With analog filters the signal was procesing and through a microcontroller was performing a temporal analysis of the fundamental EMG signal. It was performed to determine the classification of patterns to determine the intention of movement to perform and to emulate the movement to control the transradial myoelectric prosthess. These signals are sent to the computer by RS232 communication where it is displayed on a user interface developed in Blender 2.4. There it is observed, in a didactic way, the increase or decrease of force applied to each movement of muscle control and actuation of the movement performed. The project aims to provide training of movements, prehension and apprehension and rotation of upper limb of amputee users of prosthesis. It will facilitate its use and adaptations also in order to assess candidates adopt prosthesis of this type before it is prescribed, avoiding unnecessary costs to the health system and the frustration of the amputee.
