The treatments will be administered by a Realief Neuropathy Center therapist. The target surface area and treatment durations will be dictated by the Realief Therapy protocol according to their proprietary algorithm, which includes assessment of geographic areas involved and the degree of neuropathy experienced. For the trial, each patient will be given 18 treatments of 30-minute duration, scheduled every three times weekly. The treatments will include laser exposure of any or all of 27 differentiated areas of the legs, feet, cervical spine region and lumbar spine region, for durations of 3 to 30 minutes, based on the symptom presentation at the time. Power densities will vary from 5 to 12 watts, based on the symptom presentations through the course of therapy.
