Abstract

A shear force modulation system comprising an upper pad to which an upper slide is attached, and a lower pad to which a lower slide is attached, the top surface of the upper pad being adapted for contact with the skin surface and the bottom surface of the lower pad being adapted for contact with a skin abrasive surface. The upper slide is in slidable contact with the lower slide, and the upper and lower pads may be attached by coating, adhesives, and elastic, viscoelastic, or non-elastic connectors. The system may be adapted for use as an insole, bed pad, or other device which is used to modulate shear forces applied to a skin surface and thus reduce abrasion and ulceration. Time varying response to shear may also be provided by retaining a viscoelastic fluid between the upper and lower pads, or slides. Variable compliance to modulate shear forces may be provided by the application of connectors in various configurations.
