Systems and methods are disclosed which provide a way to diagnose frailty using an upper extremity (and/or other body portions) frailty assessment. Within this method, several parameters can be calculated based on the kinematics (e.g., pure motion without including forces) and kinetics (e.g., analysis of forces and moments) of, for example, joint flexion/extension. An ordinal and/or continuous frailty score can be determined based on calculated markers of frailty, such as slowness, weakness, flexibility, and/or exhaustion, while performing a short-duration upper extremity task. Patients can be classified as non-frail, pre-frail, or frail.
