Abstract
An assessment device is provided which allows for measurement of a position of interest, e.g., a body part, while a subject is in a functional position, such as may be required for the demands of an activity of interest without also requiring a lengthy setup time, tethered connection to other equipment external to the subject or tedious manual measurements. Moreover, an indicator such as an alarm or other output may be provided for receiving immediate, real time feedback, such as when a functional activity falls outside a tolerance or threshold.
