OBJECTIVE The goal of this study is to characterize the phenomenon of evoked tactile sensation (ETS) on the stump skin of forearm amputees using transcutaneous electrical nerve stimulation (TENS). APPROACH We identified the projected finger map (PFM) of ETS on the stump skin in 11 forearm amputees, and compared perceptual attributes of the ETS in nine(More)
The future development of artificial limb is to provide sensory feedback for amputee users. Cutaneous electrical stimulation is a convenient and energy efficient way to produce substituted sensory information. In this paper, we present the results of psychophysical experiments of electrotactile stimulation in normal human subjects. The purposes of these(More)
