Evaluating the effectiveness of intracortical microstimulation on fingertip sensations in a case of spinal cord injury

Takeaway

  • 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.
