Getting up from a chair is an important aspect of ADL. It is therefore a necessary quality for independent living. The sit to stand is widely used for evaluating a person's ability to stand up from a chair. Traditionally, the time needed for 5 chair rises is the only parameter that is measured. However, research with force plates and camera systems has shown that a qualitative evaluation based on kinematic and kinetic movement parameters can yield many new insights.
The DynaPort SitToStandTest, which is based on a body fixed motion sensor (DynaPort Hybrid) enables you to obtain such a qualitative evaluation. The advantage of the DynaPort Hybrid over more complex measurement systems is that the measurement can be performed by a clinician in the hospital or even in the patient's home.
the DynaPort SitToStandTest extends the clinician's view on human movement by offering reliable and objective measures. Data acquisition is based on a small and light (74g) sensor which is easy to operate and does not disturb the subject in any way. If you want to evaluate the quality (and not just the speed) of standing up from a chair and sitting down, without being confined to a motion lab, the DynaPort SitToStandTest is the tool for you.

The DynaPort Hybrid collects accelerations and angular velocities in three planes. Accelerations and angular velocity in the sagittal plane are used to calculate the trunk angle. These signals are used to identify standing up and sitting down and other events during these actions, such as seat off (the moment the body leaves the chair). Finally, several signal characteristics of the whole sit to stand, stand to sit and parts of both are determined.
