Spinal decompression is a process whereby forces are applied to the spine in a manner that maximizes spinal elongation. Spinal elongation is maximized when paraspinal muscles, the muscles that guard the spine from injury, are relaxed. When paraspinal muscles relax, applied spinal decompressive forces spread apart the bony vertebra of the spine. This relieves pressure on nerves and intervertebral discs. Where this spinal elongation occurs, the pressure may drop within the disc, which facilitated movement of fluid, carrying nutrients and oxygen inside the disc. Additionally, the reduction in pressure may help draw in herniated disc material, reducing the size of the herniation.
The NSSD (our lumbar spinal decompression machine) utilizes high-speed treatment computers to calculate the spinal decompression treatment curve for each patient. A servo-motor / servo amplifier takes the treatment curve and applies the forces to the patient. The servo-amplifier constantly checks (several thousand times per second) and corrects the servo-motor's movement. Measurement devices inside the NSSD monitor changes in the decompressive force experienced by each patient.
All of this data is constantly fed back into the treatment computers. The treatment computers continually calculate corrections and ensure the therapy is true to each patient’s treatment curve. This constant monitoring, measuring, and correcting process is called a Nested Closed-Loop Feedback system.
