Neuropathic pain
Neuromodulation is an innovative method used to treat chronic neuropathic pain that does not respond to conventional treatment. Major neuromodulation techniques include spinal cord stimulation (SCS), dorsal root ganglia (DRG) stimulation, and radiofrequency ablation (RFA) therapy. These neuromodulation techniques provide new opportunities for patients suffering from chronic neuropathic pain, improving their quality of life and providing an alternative to traditional pharmaceutical treatments.
Spinal cord stimulation (SCS) is a widely used technique in which electrodes are implanted near the spinal cord. These electrodes send electrical impulses that interfere with the transmission of pain signals to the brain, thereby reducing the sensation of pain. SCS is often used to treat pain in the back, neck, and limbs, especially after failed spinal surgeries.
Dorsal root ganglia (DRG) stimulation is a newer method that targets specific nerve ganglia that transmit pain signals. Stimulating the DRG can provide more precise control of pain in specific areas of the body, making this technique particularly useful for localized pain, such as in the leg or hip.
Radiofrequency generator uses radio waves to control pain. This technique involves using radio waves to stimulate and "switch off" the nerves that send pain signals. The RF generator delivers the RF energy through compatible cannulas and electrodes to the treatment site. The RF energy is used to raise the temperature at the therapy site and ablate the nerve tissue (thermocoagulation). This is a minimally invasive procedure that can provide long-lasting pain relief.
