Non-Surgical Spinal Decompression is said to create a negative pressure within the spinal discs causing a vacuum effect. Decompression is aimed to treat the root cause of the diseased or pathological disc.Ideally this vacuum effect is suppose to pull the bulged disc material back inside, and relieve the pressure on the nerve. This decompression procedure is typically performed using with a high tech mechanical traction machine (comprised of a computer controlled traction machine and a number of straps used to stabilize the body). Decompression machines are designed to trick the body and reduce its natural response to resist the pressure from the machine. This is the main difference between the machines and rudimentary inversion tables that basically allow a person to hang upside down.
