Evaluation of shoulder complex motion-based input strategies for endpoint prosthetic-limb control using dual-task paradigm

Yves Losier, MScEE, PhD, PEng, et al.


Figure 5. Experimental apparatus setup. Flex/Ext = flexion/extension.

In this study, we designed and evaluated two different approaches to control the endpoint of powered upper-limb prostheses. One method used the position of residual shoulder motion; the other used the myoelectric signal produced by the shoulder muscles. Both approaches were tailored for individual users through a short training protocol. The two control systems were assessed with a functional test experiment. The results showed that the residual motion-based strategy outperformed the myoelectric signal-based strategy and that neither strategy significantly increased the users' mental burden.
