MedX Medical Machines For Rehabilitation

For the most part of his adult life Arthur Jones always, not matter where he was, experimented with different ways of strengthening his body through exercise. Beginning with dumbbells and barbells he always strove to find a better way. After years of research he developed the Nautilus strength training system and once he had perfected that strength training system he then founded his MedX company and initially the Lumbar Extension machine which was a design for rehabilitation of the lower back. His new strength and rehabilitation system was based on medical research and Jones wrote many research articles about the methods and reasonings for his designs.

The 3 areas of the body that Jones recognized as being the most vulnerable to injury, for any number of reasons, are the lumbar region or the lower part of the back, the cervical region of the neck area and the knee. The very first experimental machine that he developed was the Lumbar Spine machine and once Jones was satisfied that he had produced an effective device for measuring and strengthening the Lumbar spine he went on to design a similar exercise machine for the Cervical area of the spine. This was soon followed by the design of a medical knee machine.

Eventually Arthur Jones made 5 separate medical machines, Lumbar Extension, Cervical Extension, Cervical Rotation, Torso Rotation and the Knee Extension machines. Many clinics, hospitals, fitness centers, chiropractors, neck and back began using these medical exercise machines and the true benefits of using the medx medical rehabilitation system very soon became widely recognized. Today the two Medical MedX machines that are used most are the lumbar Extension and the Cervical extension. These machines are very costly and run many thousands of dollars to purchase new and so it is more financially viable for new clinics to find a second hand or used Medx machine.

MedX Medical Machines Are No Longer Being Manufactured

The original Medx Medical machines are no longer being manufactured as the patent has expired and so the Medical Medx Machines are actually going to become a rarity. We here at have the most comprehensive listing of used or pre owned Medx machines any where in the country and are the best source for locating or purchasing the rehabilitation or strength machine that you are searching for. Many of these Medx medical machines are now classed as being Rare and it is becoming increasingly difficult to source these for purchase. However we carry a listing on this of these Rare MedX machines

The following is an extract from one of the many papers that Arthur Jones wrote called The Lumbar Spine and The Cervical Spine and the Knee. Arthur breaks down the rehabilitation process into its simplest form of these 5 points.

Kind of Exercise
Frequency of Exercise
Level of Resistance
Number of Repetitions
Style of Performance


The value of exercise for rehabilitation has been recognized in Europe for more than two-thousand years, but was generally overlooked in this country […]
