The total duration of each Sit-to-Stand cycle, from rising to sitting down again, is automatically calculated to replace manual timing.

Dynamic phases (trunk flexion and extension) and static phases (fully seated and fully standing) are identified separately, providing detailed timing for each component of the movement.

Trunk flexion and extension angles are calculated for both rising and sitting phases, offering insight into postural control during the transition.

Trunk angular velocities during flexion and extension are quantified for each cycle, capturing rotational movement patterns throughout the transitions.

Upward and downward velocities of the body’s vertical movement are derived for each rise and descent, reflecting the smoothness and vigor of the motion.

Estimated power output is calculated for both rising and sitting phases, providing an objective measure of strength and functional performance during the transition.
