Patronized sEMG Acquisition System Proposal Using Patient Journey Mapping for Upper Limb Prosthesis

Abstract:

Electromyographic signals are widely used in the study of control systems for prosthetic devices, but the way they are acquired hinders the replicability of the studies performed, generating a large variation between each measurement of the signals. One of the main problems in the acquisition of myoelectric signals is the location and repositioning of the surface electrodes, this is something that could be solved by analyzing the most common distributions and configurations of electrodes and rethinking the design of the acquisition systems, forms or methods for that are more comfortable for the patient. In this research, a prototype was built that has the acquisition points of standardized signals, which is easy to use and provides greater autonomy to the users of these systems. To develop this device, the design of the idea using the “Patient Journey Mapping” methodology, which allows finding interdependencies and friction points in the whole process of using the prototype of SEMG signal sensing, the solution is subsequently designed, building the prototype and the system for the tests performed on it.
