A peripheral neurostimulator is a medical device designed to manage chronic pain by sending mild electrical impulses directly to specific peripheral nerves—those outside the brain and spinal cord. These impulses interfere with pain signals, preventing them from reaching the brain and reducing the perception of pain in targeted areas. The system typically includes a small pulse generator, implanted under the skin, and thin leads positioned near the affected nerves. Patients or clinicians can adjust the intensity, frequency, or pattern of stimulation to achieve the most effective relief.
Peripheral neurostimulators are often used for localized pain that is difficult to manage with medications alone. Because the stimulation is highly targeted, it can provide relief to specific areas such as a limb, shoulder, or joint without affecting the rest of the body. While the device does not treat the underlying cause of pain, it can significantly improve quality of life by allowing greater mobility, comfort, and participation in daily activities. Many patients also have the option to trial the device temporarily before permanent implantation to ensure it provides meaningful pain relief.
