The NormaTec system is comprised of a control unit, and separate attachments that can go either on the legs, hips, or arms. The device inflates so it is molded to the limbs exact shape. Instead of using static compression (squeezing) to transport fluid out of the limbs, NormaTec Pulse Technology uses dynamic compression (pulsing). Feeling similar to a massage the patented pulsing action effectively mimics the muscle pump of the legs and arms, greatly enhancing the movement of fluid and metabolites out of the limbs after an intense workout.
