The Kinematic analysis of gait using three-dimensional analysis laboratories utilizes a system of cameras in standard fixed positions that capture the movement of reflective markings attached to the skin of the individual, forwarding it to a computer in order to create threedimensional movement simulations, models and visualization of real movements in a virtual environment. At least three mark...
