High-density force myography: A possible
alternative for upper-limb prosthetic control

Ashkan Radmand, PhD, et al.

Users have always had high expectations for the function of artificial upper limbs, often because of their portrayal in the popular media and comparisons with nondisabled people. Only a small percentage of patients with an upper-limb amputation regularly use a prosthesis, mainly because many patients perceive a lack of function. Externally powered prostheses can be controlled by muscle signals from the residual limb, but they can still be difficult for users to control. In this study, we investigated the use of novel high-density force sensors that measure pressure from muscle movements as a possible control input for an upper-limb prosthesis, with the goal of developing a more robust prosthetic control method. Our high-density force sensor method showed greater accuracy in recognizing movements of the wrist and hand than currently available control methods. Future work will focus on confirming these results in subjects with amputation and refining the techniques.
