Abstract:

Experiments performed in our laboratory revealed that able-bodied subjects use four high level control strategies to maintain stable quiet standing. A direct correlation between the control strategy used by a subject and the position of the subjectís center of pressure (COP) was established. Therefore, the overall COP area was divided into four zones: a high preference zone, a low preference zone, an undesirable zone and an unstable zone. Division of the COP surface into four distinct control zones is a new concept which should enable researches designing standing prostheses to better understand the basic design requirements for such devices. Potential standing prostheses, that will be designed to provide stable and safe "hand free" quiet standing, should maintain the COP position in the high and low preference zones.
