During intracortical microstimulation (ICMS) in a patient with spinal cord injury, sensations were observed on 8 digits across both hands, and projected field sizes were comparatively focal.
Why this matters
Individuals with spinal cord injury experience loss of independence, partially caused by loss of touch, which impairs ability to manipulate objects.
ICMS has been shown to restore touch in non-human primates and to evoke sensations in areas other than fingertips.
This interim report from the larger MiCNS study provides promise for ICMS as a method to provide functional tactile feedback with prosthetic hands.
