Free-Living Sit-to-Stand Characteristics as Predictors of Lower Extremity Functional Decline among Older Adults.

Performing STS transitions at higher velocities in the free-living environment can prevent a future decline in lower extremity function. This indicates that changes in daily STS behavior may be useful in the early identification of functional loss. Free-living peak STS angular velocity may be a factor underlying the longitudinal association of lower extremity strength and performance.
