The DRX9000™ True Non-Surgical Spinal Decompression™ System was created to assist healthcare providers in their effort to treat low (lumbar) back pain. The DRX9000™ provides a primary treatment modality for the management of pain and disability for patients suffering with incapacitating low back pain and sciatica. The system is designed to apply spinal decompressive forces to compressive and degenerative injuries of the spine. It has been found to provide reflief of pain and symptoms associated with herniated discs, bulging or protruding intervertebral discs, degenerative disc disease, posterior facet syndrome, and sciatica.
The DRX9000 True Non-Surgical Spinal Decompression System™ provides a primary treatment modality for the management of pain and disability for patients suffering with incapacitating low back pain and sciatica. It is designed to apply spinal decompressive forces to compressive and degenerative injuries of the spine. Non-surgical spinal decompression treatment involves a series of stretching/relaxation cycles aimed to relieve the pain and symptoms associated with herniated discs, bulging discs, sciatica and facet syndrome through unloading due to distraction and positioning.
Nested Closed-Loop Feedback
The entire DRX line of products feature Closed-loop feedback which is defined as an automatic control system that can adjust and self-correct its operation according to differences between the actual and desired output. Closed-loop feedback systems improve overall system performance.
The effectiveness of closed-loop feedback systems vary based on the variables measured, how they're measured, and how often they're measured. With respect to spinal decompression systems, the measured variable is most often force, which is the amount of tension used to distract the spine.
High Speed Nested Closed Loop Feedback
The DRX™ device series incorporates closed-loop feedback within a closed-loop feedback system, referred to as nested closed-loop feedback. As illustrated above, one of the three stops on the closed-loop feedback path in the DRX™ devices is the servo-amplifier and servo-motor. The servo-amplifier receives corrective force commands from the treatment computer 13 x per second. The servo-motor itself contains very accurate devices that measure force, speed, and power consumption. The servo-amplifier monitors these variables, correcting the actions of the servo-motor 4,000 x per second. The nested closed-loop feedback system is one of the technological hallmarks of the DRX™ device series.
