A system may include a calibration module that measures a range of limb and trunk movements made by a human subject during a calibration phase of the system. A customization module may customize pre-determined performance criteria based on the measured range of limb and trunk movements. An activity task presentation module may present an activity task to the human subject for performance during an activity phase. An activity assessment module may assess the human subjects performance of that activity task during the activity phase based on the pre-determined performance criteria.
