The rigid relief orthosis was developed to protect vulnerable sites on the plantar surface of the insensitive foot against reulceration by providing both a nonyielding relief under the healed lesion site and a total contact fit. Clinically, the rigid relief orthosis has been effective in protecting the foot against the trauma induced by the repetitive mechanical stress of walking. This study used both the Hercules and F-Scan pressure transducer systems to measure pressure at the first metatarsal head in three orthotic treatments. Both measurement systems recorded significant reductions in pressure at the first metatarsal head with the rigid relief orthosis, establishing a quantitative rationale explaining its clinical effectiveness. Significant pressure differences were also recorded at the secondary sites of the heel, midfoot, and third metatarsal head.
