What is Visual Parallax and how does it affect gait analysis? : Is your video gait analysis really telling you what you think it is telling you ?
/We recently were asked by a student at a physical therapy school to help with a teaching case. They asked us to look at a gait video to assist in outlining some things in the case. Here was our response.
“Hello Jane Doe
We are happy to look at the video for you so you and others can learn.*This blog article (link below) which we wrote 18 month ago is the heart of what we wanted you to read today. Visual parallax and binocular vision both need to be understood so that you can better understand why what you see on your gait analysis video might not be what you think you are seeing. Seeing is one thing, knowing what you are seeing is another, knowing the limitations and the “why” of what you are seeing is yet another.
So, we can tell you what we see………but without an exam we cannot tell you with great accuracy why you are seeing what we see.best
