Diabetic peripheral neuropathy (DPN) affects up to 1/2 of diabetics, both type I and II. It contributes to limb amputation, and can cause painful symptoms which are difficult to treat. Application of a high intensity, DC electromagnetic field, as supplied by the investigational device the Magnetic Molecular Energizer (MME) has shown in a pilot study with participants having DPN in their feet, to have created significant improvement in painful symptoms and improved measures of neurologic function in 7 of 10 participants. This study will enroll participants and evaluate them at baseline with regard to pain levels, nerve function and quality of life. They will then be randomized to receive 120 hr exposure to either active MME procedure, or sham procedure. Following the 120 hrs the participants will then receive the same evaluation for pain level, nerve function and quality of life. These evaluations will be repeated a final time 6 months following. The participants will be blinded to whether they receive the active or sham procedure.
