Abstract :In individuals with diabetes reducing the contact pressure can significantly decrease the occurrence of ulcers of diabetic foot. The primary objective of this study was to ascertain the optimal characteristics of insole design that effectively alleviates pressure on the plantar foot. In this study, a comparative plantar pressure analysis was performed on four types of medical insoles such as silicone medical insoles with a universal fluid layer, customized three-layer medical insoles, flat silicone insoles, and prefabricate common silicone medical insoles using experimental data obtained through the PEDAR system in both standing and gait positions. The PEDAR system in gait condition findings indicate that silicone medical insoles with a universal fluid layer, customized three-layer medical insoles (Plastazote-Silicone- Ethylene Vinyl Acetate), flat silicone insoles, and prefabricate common silicone medical insoles reduce plantar pressure by 32%, 54%, 2.5%, and 6%, respectively, compared to without insoles condition. The PEDAR system findings during the stance phase, in conjunction with medical insoles, indicate that silicone medical insoles with a universal fluid layer, customized three-layer medical insoles, flat silicone insoles, and prefabricate common silicone medical insoles reduce plantar pressure by 30%, 75%, 6%, and 23%, respectively, compared to the without insoles condition. Evidence suggests that a universal medical insole is not suitable for all patients. Therefore, individual assessments are essential to identify insoles tailored to specific patient needs.
