ORTHOSES INSERT FOR METATARSALGIA AND DIABETIC PATIENTS

摘要

A novel insole orthoses pad that may be inserted into a shoe alleviates the formation of ulcers aggravated by plantar shear forces and vertical forces. The insole orthoses pad, has vertically aligned strips of a material that support and cushion vertical forces alternated with a more flexible material that allows the supporting material to move from proximal-lateral to distal medial in response to shear forces without abrading the plantar surface. The combination of alternating strips of material are aligned so as to anticipate the orientation of the shear forces generated during the execution of a step by the wearer. ;Arcs of cushioning material are provided on a pad to protect likely sites of ulcer formation, having an orientation direction that is the average of the locus of maximum pressure in order to reduce the rubbing of the cushion material due to shear forces.
