A small device is implanted under the skin, usually in the lower back, which sends electrical impulses to the spinal cord. These impulses interfere with pain signals, reducing the sensation of pain before it reaches the brain.
Patients control the stimulation through a handheld device, allowing them to adjust the intensity based on their pain levels. SCS is typically used for chronic back pain, leg pain (such as that caused by sciatica), and complex regional pain syndrome (CRPS).
Similar to SCS but focuses on specific peripheral nerves outside the spinal cord. Electrodes are placed near the affected nerve, and electrical impulses are delivered to block pain signals from that nerve. PNS is often used for localized pain, such as headaches, facial pain, or pain following surgery.
A non-invasive form of nerve stimulation where electrodes are placed on the skin over the painful area. Electrical impulses are delivered through the skin, helping to reduce pain by stimulating the nerves and promoting the release of endorphins. TENS is used for various pain conditions, including musculoskeletal pain and nerve pain.
