A fall and/or concussion prediction system includes: (i) a measurement assembly configured to receive a subject having a surface for receiving at least one portion of a body of a subject and at least one measurement device, the at least one measurement device configured to sense one or more measured quantities and output one or more signals that are generated based upon the subject's contact with the surface; (ii) a visual display device, the visual display device configured to display a task, an interactive game, a virtual reality scenario, and/or an immersive graphic environment that is visible to the subject; and (iii) a data processing device operatively coupled to the at least one measurement device of the measurement assembly and the visual display device. In one embodiment, a dual-task protocol is used to assess a person's risk for falling and/or predict whether or not a person has sustained a concussion.
