Design and Implementation of an Electrogoniometer System for Ankle and Knee Motion Assessment in Health Care

In this paper, the design and implementation of a novel electrogoniometer system called WHITE is presented. First, the specifications of the system were gathered based on interviewing health professionals in public and private health centers. Then, the development was divided into mechanical design, electronics hardware and user interface, and its design is explained in detail. Finally, the implementation and preliminary test is performed showing that the sensory system has an error lesser than 1%, in addition it is suggested potential applications of the system. Further work will be focused on using the system for assessing functional activities and compare results with advanced motion tracking system to test its reliability and robustness.
