Spectral characterization of tremors using accelerometer and gyroscope inertial sensors

Introduction: Every human body has a tremor. The healthy condition (called basal tremor) is characterized by a low intensity shaking, whereas high intensity tremor might be pathologic or intentionally mimicked to simulate physical disability. The aim of this study is to characterize basal and mimicked tremors, using simultaneously accelerometer and gyroscope signals. Then, a machine learning approach has been applied to discriminate the two types of tremors and a new set of features is proposed.
