A spinal cord stimulator (SCS) or dorsal column stimulator (DCS) is a type of implantable neuromodulation device (sometimes called a "pain pacemaker") that is used to send electrical signals to select areas of the spinal cord (dorsal columns) for the treatment of certain pain conditions.

Neurostimulation for chronic pain is primarily through the use of spinal cord stimulators. [11] These devices deliver electrical stimulation to different areas of the spine based on where they are implanted. Since 2012, Medtronic has produced spinal cord stimulators with accelerometers that can predict the patient's position. The device can be ...
Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...

Injuries to the spinal cord interfere with electrical signals between the brain and the muscles, resulting in paralysis below the level of injury. Restoration of limb function as well as regulation of organ function are the main application of FES, although FES is also used for treatment of pain, pressure, sore prevention, etc.
In the majority of cases, spinal cord injury leaves the lower limbs either entirely paralyzed, or with insufficient strength, endurance, or motor control to support safe and effective physical training. Therefore, most exercise training employs the use of arm crank ergometry, wheelchair ergometry, and swimming. [21]
The injured spinal cord is an “altered” spinal cord. After a SCI, supraspinal and spinal sources of control of movement differ substantially from that which existed prior to the injury, [20] thus resulting in an altered spinal cord. The automaticity of posture and locomotion emerge from the interactions between peripheral nervous system ...
