Electrical stimulation of regenerative peripheral nerve interfaces
(RPNIs) induces referred sensations in people with upper limb loss
Abstract
In four participants with upper limb loss, we characterized the quality
and location of sensation elicited through electrical stimulation of
regenerative peripheral nerve interfaces (RPNIs) over time (up to 54
months post implantation of wires). We also measured sensory perception
and discomfort thresholds, sensitivity to changes in stimulation
amplitude, and ability to differentiate objects of different stiffness
and sizes.
