Abstract
［Objective］The recurrence rate of diabetic foot ulcers is high and is related to kinetic factors. We examined the changes in load on the plantar surface and performed gait measurements before and after ATL.
［Methods］A female in her 60s had five recurrent plantar ulcers over a 3-year period and was treated in a hospital. The cause of the recurrences was thought to have a kinetic component. We measured foot pressure before and after ATL and evaluated gait using a 3D motion analysis device.
［Results］Postoperatively, foot pressure measurements using a walkway showed a reduction in load on the plantar surface. Gait evaluation using the 3D motion analysis device revealed increases in the range of motion of ankle dorsiflexion, knee flexion, and hip extension in the terminal stance as well as in walking rate, gait speed, and step length.
［Discussion］Gait pattern changes due to ATL extension were evaluated using a 3D motion analysis device. By increasing the dorsiflexion angle of the ankle joint, the load on the plantar surface was reduced, and the compensatory movements of the hip and knee joints during walking were corrected, contributing to an improvement in walking speed, step length, and walking rate.
