Summary

This clinical trial is designed to assess the effectiveness of advanced neuromodulation techniques in reducing phantom limb pain by improving sensory feedback in bionic prostheses. The study will explore the use of Peripheral Nerve Stimulation to evaluate their impact on pain relief and sensory restoration. The trial aims the development of neuroprostheses that can provide sensory feedback through stimulation.

Conditions

• Phantom Limb Pain

Interventions

Type	Name	Description
PROCEDURE	Peripheral Nerve Stimulation	Peripheral Nerve Stimulation (PNS) is a neuromodulation technique used to treat chronic pain. The procedure starts with a preoperative assessment, including imaging to identify the target peripheral nerve. Under local anesthesia, a thin, insulated electrode is implanted near the nerve, usually with the help of fluoroscopic or ultrasound guidance for precision.
PROCEDURE	Spinal cord stimulation	Spinal Cord Stimulation (SCS) is a neuromodulation that involves the implantation of a device that delivers electrical impulses to the spinal cord through an electrode placed in the epidural space. The stimulation alters pain signals before they reach the brain, effectively masking or reducing the sensation of pain.
PROCEDURE	Dorsal Root Ganglion Stimulation	Dorsal Root Ganglion Stimulation (DRGS) is a targeted neuromodulation technique for managing chronic pain. The procedure begins with a thorough preoperative assessment, including imaging to locate the specific dorsal root ganglion (DRG) associated with the pain. Under local anesthesia, a small electrode is implanted near the DRG. This is done through a minimally invasive procedure, often guided by fluoroscopy or CT imaging to ensure precise placement.
PROCEDURE	Motor Cortex Stimulation	Motor Cortex Stimulation (MCS) is a neuromodulation technique that involves the surgical implantation of electrodes over the motor cortex, typically targeting the precentral gyrus, to deliver electrical stimulation. The procedure involves placing an electrode grid or strip on the dura mater overlying the motor cortex, which is identified via neuroimaging techniques such as functional MRI or neuronavigation. Once implanted, the electrodes are connected to an implanted pulse generator (IPG), which delivers adjustable electrical impulses.
