1. A kinematic system including a plurality of kinematic devices comprising:
- a first kinematic device comprising;
an attachment mechanism to attach the first kinematic device securely to a subject at a first movement segment of the subject'"'"'s body location, the location selected based on a type of motion of the subject to be evaluated;
a projector to project a first light line and a second light line perpendicular to the first light line; and
a multi-directional joint to enable a portion of the first kinematic device to move independently of the attachment mechanism, the multi-directional joint enabling an adjustment of the first kinematic device so that the first line of light is aligned along a horizontal axis and the second line of light is aligned along a vertical axis; and
a second kinematic device for attachment to a second movement segment of the subject'"'"'s body, the second kinematic device designed to project a first light line and a second light line, wherein the first and second kinematic devices demonstrate motion of one or more joints between the first and second movement segments;
wherein movements of the subject cause movements in the first and second lines of light of the first kinematic device and the second kinematic device, the movements in the lines of light used to evaluate a movement quality of the subject showing rotation, anterior-posterior tilt, and lateral tilt at the one or more joints, based on the relationship of the movements of the lights from the first and the second kinematic device, thereby providing immediate visual feedback.
