This video demonstrates using the Motion Guidance system during open quad setting, adding visual cues to maximize performance of full knee extension: simply passively move the knee into full extension, set the laser at the toe, and have the user "get back there" with each quad set: if the laser doesn't hit the toe, they are not utilizing their full extension! A great MG application post TKA or ACLR.
