Spinal Cord Stimulation
A Spinal Cord Stimulator(SCS) or Dorsal Column Stimulator (DCS) is an implantable medical device used to treat chronic pain of neurologic origin. An electric impulse generated by the device near the dorsal surface of the spinal cord provides a paresthesia (”tingling”) sensation that alters the perception of pain by the patient.
A trial is usually done before the permanent unit is placed. A temporary percutaneous lead is used and is connected to an external pulse generator. The trial is from 3 to 7 days. If the patient has at least 50% improvement in pain during the trial, the patient is considered a candidate for the permanent unit.
