This test has become a clinical standard with several variations:

• 30-Second Sit-to-Stand Test (30STS) – how many repetitions can be completed within 30 seconds?
• 5-Repetition Sit-to-Stand Test (5STS) – how quickly can 5 repetitions be completed?
• “Functional” Sit-to-Stand Test (FSTS) – assessment of the ability to perform the task and the quality of the movement (for example asymmetry, range of movement (ROM) and movement quality).
