Effect of biofeedback-assisted relaxation training on foot ulcer healing

A prospective, randomized study was conducted to determine the effect of biofeedback-assisted relaxation training on foot ulcer healing. For patients with chronic nonhealing foot ulcers, medical care was combined with a standardized biofeedback-assisted relaxation training program in the experimental group. The intervention was designed to increase peripheral perfusion, thereby promoting healing. A total of 32 patients with chronic nonhealing ulcers participated in the study. In the experimental group, 14 out of 16 ulcers (87.5%) healed, as compared with 7 out of 16 ulcers (43.8%) in the control group.
