There's a part in there were it shows the fascia clamping down around the nerves and blood vessels. I think that's a big issue if you've had TOS for a long period of time. The facsia tightens up to protect the nerves, and after a long period of time, it stays that way, causing pain and movement restrictions. That's why myofascial release is so important.

That video shows what healthy fascia looks like. I wonder if bound up, unhealthy fascia looks different?
