Electromyographic signals as analytical and hardware tool for alternative communication

Abstract

The present study shows electromyography interface as positive control for Alternative and Augmentative Communication (AAC). The aim of this work was to relatio electromyography signal as entrance dipositive for positive control to choose switchs on AAC. Tthis had support on clinical-qualitative and descritive methods, three subjects were selected for this research, two with cerebral palsy and one with Spinal Muscular Atrophy. After the selection of the subjects, were made evalutions with Alternative Augmentive Communication Neurofunctional for Choosing Switchs Protocol (AACNS). In this context, the neurofunctional evalution using the AACNS guided the selection of switchs regions; after the switchs were made, electromyography test in instrumentalization day was realized. The results found using EMG confirm the group muscle group chose by AACNS indicate the correct switchs. EMG tests facilitate and confirm the switchs chooses with support of positive control.
