Many prosthetic limb users experience problems related to prosthetic socket fit and phantom limb pain. The use of prosthetic socks can reduce discomfort from wearing a prosthetic limb. Electrodes integrated in the sock can be used to pick up muscle activity signals to control a virtual arm in phantom limb pain therapy. As no two residual limbs are exactly the same, a mass-produced sock won´t fit everyone. The MedTech West associated researcher Li Guo from Smart Textiles at the University of Borås has received a grant from The Knowledge Foundation for investigating textile methods to address these problems. This project- ongoing for two years- aims to develop smart textile solutions to improve user comfort by developing a personalized prosthetic sock.
– If the prosthesis is uncomfortable, the person won´t wear it, says Li Guo. Smart Textiles enable the design and production of a functional textile interface between the residual limb and the socket of the prosthetic device to improve wearability and comfort.
The project will combine cutting edge technology with smart textiles, and, in addition to the University of Borås, the knowledge of the three industrial partners Integrum AB, Bola AB and Lindhe Xtend AB.
