Project Overview

The project seeks to measure spatio-temporal parameters suitable for accurately detecting gait instability in elderly individuals. Using one tri-axial accelerometer located on the S2 vertebra and two dual-axis accelerometers on the heel columns, the data obtained can be used to make accurate conclusions on the gait instability of the subject. With a focus on trunk acceleration to maximize accomplishments, the team purchased a commercial logging device with customized accelerometers. To venture into the possibility of simplifying the commercial product, a circuit was designed and constructed to accommodate further adjustments and reductions in size in accordance with the client’s needs and possible variability among subjects. An attachment device was also made to fix the tri-axial accelerometer and data logger securely to the subject.
