*Abstract

Sensory devices have the potential to impact monitoring balance tests and providing quantitative supports for activity analysis. The Wearable Gait Lab system has been developed to monitor activities of legs and feet during static and dynamic balance tests. In this system, a wearable underfoot force sensing unit in the form of a wearable insole, is used to record motions of the feet and plantar pressure data; a joint angular and EMG (electromyographic) sensing unit is used to record leg motions and muscular data; and an android application is implemented to control all units, monitor data recording process, and upload recorded data to a cloud server, which allows medical professionals to review it remotely. An array of various embedded sensors can be deployed to assign a clinical parameter to a risk of a slip, trip, or fall event. The system provides adequate data for balance ability analysis and simplifies the scoring processes in balance tests, which improves medical professionals' work efficiencies. The proposed system is evaluated with standard balance tests (Limits of Stability, Unilateral Stance and Sit-To-Stance), whereas the data collected are analyzed with data mining techniques to verify the reliability of the designated process. Certain parameters are computed such as center of gravity (COG), standard deviation, and sway velocities. The results show that the system is informational and reliable in the process of determining balance status during tests with additional advantages of simple procedures and efficient review communications.
