Closed-loop Spinal Cord Stimulation: Restoring Foot Sensory Feedback and Alleviating Phantom Limb Pain
Researchers have demonstrated the successful restoration of sensory feedback from the foot and reduction of phantom limb pain in individuals with lower-limb amputations through closed-loop spinal cord stimulation. By stimulating the spinal cord in response to pressure sensors on the sole of the foot, the study participants were able to perceive sensations in their missing limb and experience relief from phantom limb pain. This breakthrough could significantly improve the quality of life for amputees and pave the way for the development of more advanced neuroprosthetic devices.
