nevrostimulator

A nevrostimulator, also known as a neurostimulator, is a medical device that uses electrical impulses to modify nerve activity. These devices are implanted in the body to treat a variety of chronic pain conditions and neurological disorders. The primary mechanism involves delivering electrical stimulation to specific nerves or areas of the central nervous system.

The use of nevrostimulators has expanded significantly in recent years. They are commonly employed for conditions such as chronic back pain, failed back surgery syndrome, and complex regional pain syndrome. In some cases, they are also used for conditions like Parkinson's disease, epilepsy, and urinary incontinence. The electrical impulses generated by the nevrostimulator can disrupt pain signals traveling to the brain or modulate abnormal nerve activity.

The implantation procedure typically involves surgery to place electrodes near the target nerves and a pulse generator, often referred to as a battery pack, under the skin. The patient can then control the device's settings, such as the intensity and frequency of stimulation, through an external remote. Different types of nevrostimulators exist, targeting various areas like the spinal cord (spinal cord stimulation), peripheral nerves, or the brain (deep brain stimulation). While generally considered safe, potential risks and side effects can include infection, lead migration, and changes in sensation.
