EXPERIENCE WITH SILICONE SUCTION SOCKETS USI NG MYOELECTRIC CONTROL

Abstract

The use of silicone or similar material with distal attachment as a suspension system has gained great acceptance and usage for lower limb amputees. Since its introduction in the mid 1980’s by Kristinsson, the silicone suction socket (3S) has undergone extensive development and the options available have proliferated due to its popularity. Benefits for the lower limb include: reduced shear forces on the skin, better pressure distribution especially when a gel type liner is employed, and excellent suspension. Shortly after its introduction, 3S technology was applied to upper limb fittings. [2] Some early success was achieved and results were promising. Problems existed related to inappropriate sizing of liners and locking system for utilization in upper limb applications and difficulty interfacing myoelectric control in combination with 3S suspension.
