drx9000 300x200The DRX9000 True Non-Surgical Spinal Decompression System™ provides a primary treatment modality for the management of pain and disability for patients suffering with incapacitating neck, low back pain and sciatica. It is designed to apply spinal decompressive forces to compressive and degenerative injuries of the spine. It has been found to provide relief of pain and symptoms associated with herniated discs, bulging or protruding intervertebral discs, degenerative disc disease, posterior facet syndrome and sciatica.

As it relates to Axiom Worldwide’s DRX technology, the theory behind non-surgical 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 causing a vacuum effect which is believed to facilitate the movement of fluid, carrying nutrients and oxygen inside the disc. Additionally, the reductions in pressure may help draw in herniated disc fluids, reducing the size of the herniation.

DRX9000™ Nested Closed-Loop Feedback System

All of Axiom’s DRX™ devices contain Nested Closed- Loop Feedback Systems that ensure therapy stays true to each patient’s spinal decompression treatment curve.

Closed-loop feedback can be 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 or traction systems, the measured variable is most often force, which is the amount of tension used to distract the intervertebral segments of the spine.

In systems where the lower back is forced to move with the table or motor, fixed measurements are made between the motor and the patient. In systems that incorporate a floating lower mattress, force is usually measured via the tension strap. How often feedback is monitored varies significantly between currently marketed devices. These rates range from several times per minute, to several times per second, to thousands of times per second.

The DRX™ device series uses a very accurate force measurement device to record force on the tension strap during treatment. This measurement is sent to the treatment computer and is used to calculate corrective spinal decompressive forces. The treatment computer sends corrective force commands 13 x per second to the servo-amplifier and servo-motor, which then apply the spinal decompressive forces to the patient. The closed-loop feedback system runs from the force measurement device, to the treatment computer, to the servo-amplifier / servo motor and back again, 13 x per second. Therapy on the DRX™ series of spinal decompression devices takes this concept one step further.

The DRX™ device series incorporates a closed-loop feedback system within a closed-loop feedback system, referred to as nested closed-loop feedback. As described 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 measurement devices that measure position, speed, and power consumption. The servo-amplifier monitors these variables, correcting the actions of the servo-motor 4,000 x per second. This explains the nested closed loop feedback difference that separates the DRX™ series from all other decompression devices. The nested closed-loop feedback system is one of the technological hallmarks of the DRX™ device series.
