The DynaPort MT measures 3-dimensional accelerations and angular velocities. These signals are used to identify standing up and sitting down and other events during these actions, such as maximum flexion angle. Finally, maximum angular velocities and angular range of motion of the Sit-to-Stand and Stand-to-Sit are determined.


In comparison to force plate measurements the Sit to Stand method instrumented by the DynaPort MoveTest shows high agreement for both the sit-stand and stand-sit events in supervised conditions [1]. With the Sit to Stand module differences between young and elderly subjects have been shown [2]. Additionally, a method of seat-off and seat-on detection has been evaluated [3]. Recently the Sit-To-Stand test instrumented with the DynaPort MoveTest showed stronger associations with health status, functional status and daily physical activity of older adults than manually recorded test durations [4].
