Twenty years ago John Kelly, the owner of Austin Personal Training and New Orleans Fitness Trainers, had been living with chronic back pain for three years. Sitting was painful; he avoided long trips and going to the movies. Even at night school which would often last more than two hours he would stand the entire time. He did everything he could short of the recommended surgery to alleviate it; he walked, swam, stretched, and bought a new bed. About this time he began using the MedX Lumbar machine in a doctor's office twice a week and then once a week. Over several weeks his back finally became pain free. Studies show others have had similar results. For the last twenty years he has remained pain free except in rare times when he has strayed from a regime of regular exercise for his back. Others have had such profound improvement in the health of their lower back they have bought this $7000 piece of equipment for their home.
With ARRAY, each topic presented at a MEDX Regional Conference culminates in thorough analytics using multiple criteria and measurement techniques. Analytics are designed to accurately assess participant engagement, changes in participant knowledge, competence, and performance, while helping to identify needs, gaps, and barriers that can be addressed in future CME activities.
MedX reduces the friction of traditional equipment from 30% to 0 and 5% friction. This makes a big difference in the ‘positive’ and ‘negative’ phases of resistance–when you push the weight up, and when you let it back down again.  If you had 100 pounds on a machine with 2% friction, you would be pushing 102 pounds during the positive phase of the movement and resisting 98 pounds during the negative phase. This is a four pound difference between pushing the weight up and letting it down. On traditional equipment, with 30% friction, that 100 pounds turns into you having to push 130 pounds during the positive phase and resisting 70 pounds during the negative phase, for a total difference of 60 pounds. That gives your muscles plenty of time to recover on the downswing, which severely impacts your ability to properly stimulate your muscles.

Jed was raised in Salt Lake City, UT. Growing up, he always showed strong interest in the medical profession. In junior high and high school, he volunteered at a number of hospitals in Salt Lake where he gained invaluable experience that later resulted in a job as a Certified Nursing Assistant. After time working in the nursing field, he went on to work as a Physical Therapy Tech where he discovered an even deeper passion for physical therapy. Jed attended Brigham Young University-Idaho for his undergraduate degree in Biology, and then completed his Doctorate of Physical Therapy (DPT) at Missouri State University. He’s currently an active member of the American Physical Therapy Association, and loves helping his Patients return to pain-free living, and their normal routines and hobbies. When Jed is not in the clinic treating patients, he’s spending time with his family, and enjoys photography, boating, waterskiing, golfing, bowling, four-wheeling, and watching movies.

The district sweeps in the old Chicago Democratic machine wards of 11, 13, 14, 19 and 23 and meanders through a corridor to wide swathes of southwest suburban turf. The district was drawn to protect Lipinski, whose father, William — a former congressman — is close to House Speaker Mike Madigan, D-Chicago, who is also the chairman of the Democratic Party of Illinois.
A study by Dr. Brian Nelson from Minneapolis, MN, reflects how these results can be achieved. 935 patients were involved in the study. A majority of these patients suffered from chronic back pain (pain over a period of more than six months) and were previously unsuccessful with traditional therapy. After 18 sessions the success rate of MedX therapy strengthened 85% of patients’ previously weak lumbar muscles, with average strength gains of 63.91%.
Cams on strength training equipment need to support the strength curves in the body. The cams on most equipment are incorrect in this regard. On the MedX Lumbar Extension machine, for example, the cam/strength curve ratio is 1.4 to 1. That means that a normal lumbar muscle should be 1.4 times stronger in the flexed position than in the extended position. For example, if we put 100 pounds on the machine, then at the beginning of the movement you would be pushing 100 pounds. As you moved through the full range of motion to the fully extended position, the cam would be moving so that the weight would continue to lighten so that at the end of the movement that 100 pounds would have smoothly lightened to 71.4 pounds. Each muscle has a different natural strength curve so each piece of equipment should have a different cam. For example, if you put 140 pounds on the Leg Extension machine it would start at 120 pounds in the fully flexed position, increase to 150 pounds within the first fifty degrees, and then it would decrease to less than 50 pounds in the fully extended position. Each machine needs to be properly calibrated and designed to accommodate the muscle group it is targeting.
MedX offers a short one foot weight stroke, as compared to most equipment which has a weight stroke of two or more feet. This means that the weight stack movement of only one foot on a full-range repetition is safer and smoother than the competition with a longer weight stroke. A long weight stroke can also effect the amount of weight that you are effectively moving when you use the machine.
