A DEVICE AND RELATIVE METHOD FOR DETERMINING EXTRAPYRAMIDAL SYMPTOMS, IN PARTICULAR MOTOR SYMPTOMS OF PARKINSON'S DISEASE

摘要

The present invention refers to a method, and a related device, which determines a kinetic state of a subject and includes the following operations: The determination of a signal indicative of the acceleration trend (a_x, a_y, a_z) on the three Cartesian axes (X, Y, Z); - The signal processing to limit the frequency band and preferably reduce artifacts and compensate the offset of the output signals from the multi-axial measurement system; The frequency analysis and spectral analysis through the transformation of the signal with the Fournier transform; The computation of the power spectral density (E) for each axis (S_x, S_y, S_z); And in which a comparison is made between said power spectral density (E) with a characteristic pattern of a movement.
