The dorsal root ganglion (DRG) stimulation device is a pacemaker-like implant that targets specific nerves along the spine to relieve chronic pain. It works by sending small electrical pulses through wires placed near nerve clusters called dorsal root ganglions, which act as gateways for pain signals between the body and brain. Research shows this treatment can be quite effective - patients experienced an average 33% reduction in pain levels and 27% reduction in disability. About 94% of study participants found it beneficial. The device can provide sustained pain relief for 18+ months and may help reduce reliance on pain medications. However, some patients did experience complications requiring additional procedures. DRG stimulation has advantages over traditional spinal cord stimulation because it can target specific pain sources rather than sending pulses along the entire spine. It also requires less electrical current to achieve pain relief. The stimulation replaces pain sensations with mild tingling or numbness.
