The Five Times Sit-to-Stand Test (5xSTS) measures lower-limb functional strength, balance integration, and transitional mobility by timing how long a person needs to stand up and sit down five times from a chair. Slower performance is associated with falls, frailty, and disability risk, and it is commonly used in geriatrics and rehabilitation settings.
Formula: 5xSTS result is the measured time in seconds to complete five full sit-to-stand cycles.
5xSTS cutoffs vary by setting and population; values around 12-15 seconds are commonly used pragmatic risk bands in older-adult screening.
Longer completion times suggest lower functional reserve and support targeted exercise, fall-prevention, and mobility planning.
Use in older adults and mobility-limited patients in primary care, geriatric clinics, and rehab assessment pathways.
Results depend on standardized chair height, arm-use instructions, and safety considerations; severe pain or neurologic deficits can confound interpretation.

Calculate usual gait speed over 4 meters (m/s), a key functional vital sign in older adults.
GeriatricsAssess mobility and fall risk with the Timed Up and Go (TUG) test. TUG >12 seconds indicates high fall risk. Times the performance of standing, walking 3 meters, turning, and returning to seated.
GeriatricsEstimate lower-extremity functional performance with SPPB total score (0-12) from balance, gait speed, and chair stands.
GeriatricsScreen frailty using the 5-item FRAIL scale (Fatigue, Resistance, Ambulation, Illnesses, Loss of weight).
