Claim:
1. A system for automatically quantifying mobility of a user when the user is performing a mobility diagnostic procedure whereby the user transitions from a sitting position to a standing position, wherein the diagnostic procedure includes a leaning forward phase whereby the user leans to a leaning forward position prior to standing, followed by a lift-up phase whereby the user transitions from the leaning forward position to the standing position, the system comprising: at least one sensor for sensing angular movement of the user, the at least one sensor configured to provide sensor data indicative of the angular movement; a processing element for executing logic, the logic configured to automatically identify, based on the sensor data, a transition from the leaning forward phase to the lift-up phase and to quantify, based on the sensor data, at least one first mobility parameter for the user during the leaning forward phase and at least one second mobility parameter for the user during the lift-up phase, the logic further configured to determine and display a mobility indicator indicative of the mobility of the user based on the at least one first mobility parameter and the at least one second mobility parameter; and wherein the at least one first mobility parameter is indicative of angular movement of the user during the leaning forward phase and is indicative of a duration of the leaning forward phase, wherein the at least one second mobility parameter is indicative of angular movement of the user during the lift-up phase and is indicative of a duration of the lift-up phase, and wherein the logic is configured to determine the mobility indicator by summing the duration of the leaning forward phase multiplied by a first weight and the duration of the lift-up phase multiplied by a second weight that is different than the first weight.
