The Sit-to-Stand Movement recovery after stroke and objective assessment

The Sit-to-Stand (STS) movement can be described as the change in body posture\nfrom a sitting to standing position. In more biomechanical terms, it can be defined\nas a transitional movement to the upright posture requiring movement of the center\nof mass from a stable to a less stable position over extended lower extremities. The\nSTS movement is an important skill because it is related to functioning and mobility,\nand is a prerequisite for walking. The execution of the STS movement varies within\nand between persons, because many factors influence the way how people perform\nan STS movement, e.g. seat height, arm rests, feet position, age, and lower extremity\nmuscle strength. Literature indicates that also health condition, e.g. neuromuscular\ndisorders, joint disorders and stroke, can result in specific changes in the execution\nof the STS movement.
