There is a danger in relying on a patient's own report of his or her abilities. Patients may not recognize a decline in physical function. Or if they see the change, they may not think it's a problem. Tests to measure performance and physical function are available. Such tests may help identify problems earlier and more often than self-report by the patient.

A physical therapist can carry out tests of strength, balance, motion, and coordination. Finding out what changes have occurred in the patient's daily activities will help guide the therapist. A program to regain lost skills or prevent decline of current skills is important for all aging adults.
