Use of Experimental Padded Hosiery to Reduce Abnormal Foot Pressures in Diabetic Neuropathy

Abstract

High pressures under the feet of diabetic patients with neuropathy are associated with the development of plantar ulceration. The aim of management is the reduction of such stresses with orthoses and insoles. An American hosiery manufacturer has developed socks designed to reduce stress on athletes' feet, and we report a preliminary evaluation of this technique in the reduction of elevated plantar pressure in 27 neuropathic diabetic patients. With a computerized optical pedobarograph, three footsteps on each side were recorded under three conditions: 1) barefoot, 2) wearing the patients' own hosiery, and 3) wearing experimental patented padded hosiery. The patients' own hosiery did not have a significant effect on plantar pressure, but the experimental hosiery reduced both peak forefoot pressure and the area under the timepressure curve (P < .001) by a mean of 26 and 29%, respectively. We conclude that the experimental hosiery is effective in reducing vertical pressures under the diabetic foot and, in conjunction with established orthotic techniques, may be a useful addition to the treatment of the diabetic patient at risk for foot ulceration.
