Evoking referred sensations of missing digits by electro-tactile stimulation: Preliminary tests

Abstract

Sensory feedback is an important component in a prosthetic device. However, due to technological limits, current prosthetic digits aimed to treat partial hand amputations do not provide individuals with cutaneous touch feedback. In this work, we propose to employ electro-tactile stimulation to promote, by the application of stimulation electrodes on the palm, sensations relative to the missing digits. The promising findings of tests on 20 able-bodied participants are presented in this abstract.
