A Kinematic Comparison Between Sit-to-Stand Movements and Individual Cycles of the 5-Cycle Sit-to-Stand Test.

Objective: The 5-cycle sit-to-stand (5XSTS) test is frequently used to test physical function for different clinical populations, with time to complete as the measured outcome. This study evaluated the similarity of kinematics between a single cycle of the STS movement and individual cycles of the 5XSTS test.

Methods: Lower extremity, pelvis, and thorax kinematic data were monitored as 20 participants (aged 18-40) completed 5 trials of the STS movement and 1 trial of the 5XSTS test.
