The development of a platform for the evaluation of control algorithms of functional stimulators commanded by the surface electromyogram of the same electro-stimulated muscle is described. It is conformed by a stage of conditioning and other processing. The first carries out the removal of the electrical stimulus artifact and the amplification and filtering of the signal. The second stage provides a processing environment for the implementation of algorithms and allows the creation of a control signal to the stimulator. The prototype was tested with simulated and real signals, evaluating the removal of the artifact, signal amplification, the frequency response of the filters, adquisition and storage of data. The results showed good performance of the artifact's suppressor, very good SNR of the signal conditioned and high reliability in storing the digitized data, obtaining a suitable tool for rapid assessment of algorithms.
