Diabetic ulcers: the effect of thermal biofeedback-mediated relaxation training on healing

The present study was a preliminary investigation into the effect of thermal biofeedback-mediated relaxation training on healing of diabetic ulcers. Subjects were three males who had nonhealing diabetic ulcers of the toe, ankle, and leg, respectively. Treatment consisted of thermal biofeedback training at the ulcer site, handwarming training (in two of the three subjects), and home relaxation practice. Two subjects showed significant healing. Thermal biofeedback-mediated relaxation training may be a useful adjunct to traditional treatments for diabetic foot ulcers.
