The present study aims to use the SensMode System - a system composed of wearable devices for upper and lower limb movement analysis and electronic device for data acquisition and processing - on healthy subjects, subjects with idiopathic hyposmia, patients with Parkinson's disease, and subjects with de-novo drug-naïve extrapyramidal syndrome. The purpose is to identify normative data of objective motor measures obtained with such a system, as well as to increase knowledge about the potential contribution such a solution can make to the preclinical diagnosis of Parkinson's disease and the management of patients with this disease.

Motor Data Analysis
DeviceThe SensMode System includes wearable devices for upper and lower limb motion analysis. The upper limb device, SensHand, consists of 3 sensorized elements: 2 sensorized rings to be placed at the level of the distal phalanx of the thumb and forefinger of the hand and 1 sensorized wristband to be placed at the level of the distal portion of the forearm near the wrist. Each element of SensHand allows the acquisition of inertial data with respect to the biomechanics of the arm-forearm-wrist and the first three fingers of the hand, measuring the 3 components in space of linear acceleration, angular velocity, and magnetic field. The lower limb device, SensFoot, is a device that integrates the same electronic components as the bracelet and is placed in a plastic housing shaped like a small rectangular parallelepiped that is placed over the shoe.
