Abstract
The sit-to-stand (STS) maneuver is a common aspect of mobility. In the following review, the mechanics of the maneuver are briefly reviewed. Thereafter, alternatives for measuring STS performance are described. The Five-Repetition STS Test (FRSTST) is discussed in detail. This discussion emphasizes the measurement properties of the test. For clinicians working with older adults, there is considerable support for using the FRSTST as a measurement of mobility.
