For the treatment of Rheumatoid Arthritis and Hand Osteoarthritis, focused on optimal hand coordination, feedback regarding the coordination of the intrinsic and extrinsic muscles is essential.
We have developed a new device to provide this feedback, by means of pressure sensors attached to a cone that register and visualize the distribution of hand pressure on a screen: the E-cone. In clinical practice, the E-cone has been successfully used as a treatment device; patients can easily interpret the image on the screen, and use this as cue to improve their handgrip.
