Abstract
A system for determining pivot centers for proximal and intermediary articulations of an appendicular skeleton. The system includes a single marker affixed to a bone, the marker having a signal transmitter; a sequence involving at least one movement for moving a portion of the appendicular skeleton; a signal receiver for collecting data points correlating to the position and orientation of the marker; at least one processing device for selecting a number of skeletal positions during the sequence using the collected data points; and for assigning a value to each posture representing the position and orientation of the marker in a predetermined point of reference, and an algorithm for determining the coordinates of the rotational centers of the proximal and intermediary articulations using the assigned values.
