Abstract: There is provided a system and method for determining a fall risk of a subject a gait stability score for the subject from at least two gait metrics or a walking orientation randomness metric (WORM) score. If one or more of the scores falls outside a predetermined range or above a predetermined threshold the subject is at risk of falling.

Abstract: There is provided a system for determining a quantitative gait score, the system comprising an accelerometer, a magnetometer, a gyroscope; and a processor configured to receive output signals from the accelerometer, a magnetometer, a gyroscope and analyse the signals to determine the quantitative gait score for the subject from one or any combination of daily step count; step cadence; step time; step time asymmetry; step length; stride length; step length asymmetry; single support time variability; walking orientation randomness metric (WORM Score); and gait velocity or gait velocity variation. Methods of determining the quantitative gait score are also provided.

Abstract: A surgical tool for positioning a surgical device including a gripping portion; a rod protruding from the gripping portion; and a coupling system. The coupling system comprises an axial retention assembly comprising, at a free end of the rod, two opposite semispherical portions, wherein the respective flat surfaces are separated from each other by an axial notch made partially along the rod, and a central clutch movable between a locking position and a disengagement position. In the locking position, the central clutch approaches the free end of the rod and is interposed between the two semispherical portions, preventing the reciprocal approach thereof so as to block the two semispherical portions within a seat of said surgical device. In the disengagement position, the central clutch moves away from the free end and the two semispherical portions can approach to allow the tool to come out of the surgical device.

Abstract: There is provided a system for determining severity of an impact and/or a post impact risk score for a subject, the system comprising an accelerometer configured to output signals indicative of movement of the subject along one or any combination of an x-axis, a y-axis, and a z-axis; a magnetometer configured to output signals indicative of variations in position of the subject in a space defined by the x-axis, the y-axis, and the z-axis; and a gyroscope configured to output signals indicative of angular velocity of the subject around one or any combination of the x-axis, the y-axis, and the z-axis; and a processor configured to receive the output and analyse the output signals to determine for the subject one or any combination of Impact Force, Stun Time, Sway Time, Slow Time and Sway Score, wherein the x-axis is a horizontal axis to the ground directed forward of the subject's body; the y-axis being a horizontal axis to the ground directed laterally of the subject's body; and the z-axis is vertical axis to
