Study of Phantom Limb Pain Suppression Using Neuromodulation Methods

Recruiting now · Not applicable

Conditions studied: Phantom Limb Pain

In brief

This study assesses the effectiveness of neuromodulation in alleviating pain through the stimulation of peripheral nerves. The research involves implanting electrodes for test stimulation of peripheral nerves (PNS - Peripheral Nerve Stimulation), spinal cord (SCS - Spinal Cord Stimulation), dorsal root ganglia (DRGS - Dorsal Root Ganglion Stimulation), and motor cortex (MCS - Motor Cortex Stimulation). The study aims to explore the use of neuromodulation for pain relief in patients experiencing pain due to upper or lower limb amputation.
