Analysis of subtle movements related to neurodegenerative diseases using wearable inertial sensors: A study in healthy subjects

Evaluation of movement disorders is a useful tool for the diagnostic and monitoring of diseases related with damage of the motor control systems, such as Parkinson's disease. The evaluation of well characterized movement disorders has been proposed using different techniques each one with their advantages and limitations. This document propose the use a system based on inertial sensors and wireless technology for the measurement and evaluation of three of the most common movement disorders related with Parkinson's disease. Measurement of Anticipatory Postural Adjustments (APAs), Postural Sway and hand's tremor were carried out using inertial sensors modules (IMU). Results obtained from measurements in elderly and young subjects are presented, as well as the set up and parameters suggested for quantitative analysis.
