I have found when it comes to traction. It matters how its set up and were the pain is as to if it helps me. The are many other types of PT we can use, and I’ve used quite a few. You might even try a tens machine . It was very beneficial to me. I need to figure out how to get it useable for me again. And when it comes to the cognitive issues. My problems with cognitive started after the second head injury. I think it just makes a difference were your injury is, and how bad it is.
