A single SENSUS device will often provide pain control in both legs, and in fact throughout the body. Although SENSUS is typically placed on the leg, transcutaneous electrical nerve stimulation is thought to work through the central nervous system. The optimal placement for SENSUS is on the upper calf, one to two inches below the knee. This placement allows the device to stimulate the sensory nerves that travel from the lower legs and feet to the brain through pathways in the spinal cord. The stimulation prompts the body to release natural peptides (i.e., small proteins) called enkephalins that decrease the perception of pain. Because these pain relieving chemicals are released from the central nervous system, the pain relief will typically be widespread, not just in the immediate area where the device is placed.
