MPDD- An instrument to find what causes your pain.In order to move a muscle and see if it is painful, I developed an instrument with the cooperation of the Stevens Institute of Technology that can move one muscle at a time and find which muscle in a region of the body is the cause of your pain. It is called the Muscle Pain Detection Device (MPDD). It works by being able to stimulate the nerve fibers that produce muscle pain in the area where they are most often found, the parts of the muscle that attach to the tendon and the tendon to the bone as well as stimulating the trigger points. By stimulating the muscle in this way we can more accurately identify the muscle that causes your pain and my colleagues at NYU School of Medicine Pain Center actually tested the instrument in comparison with pressure to the suspected muscle (manual palpation) and showed that MPDD was much better.
Once you have found the muscle that causes your pain instead of an area where you only feel the pain, any treatment that you receive will work better-because you’re now treating the right spot. I have had many patients who were thought to have pain in their low back that actually came from their buttock or thigh muscles.
Even more unusual are the patients who have been diagnosed with serious problems, where overlooked muscles, diagnosed with the MPDD, were actually the major reason for their pain. Some of the diagnoses they had were Herniated Discs, Rotator Cuff Tear, Spinal Stenosis, Reflex Sympathetic Dystrophy now called Complex Regional Pain Syndrome, and many more. In future blogs I will be giving you examples of these patients’ experiences and how they eventually got better.
