LEGSys™ is a wireless wearable system based on 9 degree-of-freedom inertial measurement sensors. LEGSys™ is intended for measuring spatiotemporal parameters of gait based on the joint angles of the lower limbs during human walking over ground or on a treadmill. Additionally for patients aged 70 and up, LEGSys™ is intended to assess a patient’s risk of falling based on measured spatiotemporal parameters of gait and published, publicly available, scientific data regarding fall risk.
An electrically-powered, wearable device (e.g., wristband, watch, finger probe, head-worn sensor) designed to continuously or intermittently measure and record multiple physiological parameters [e.g., heart rate, respiration rate, electrocardiograph, haemoglobin oxygen saturation (Sp02), routine body movement] using one or more technologies [e.g., photoplethysmography (PPG), reflectance pulse oximetry, electrocardiography, accelerometry). The data is typically transferred to a local application (e.g., smartphone) or central database for analysis, which might include evaluation of lifestyle factors (e.g., energy expenditure, activity level, sleep patterns).
