Questions about LE neural tension/flossing
Hello, I just watched the Neural Tension Sensitivity & Testing Video from the mini-course and I have some questions. I guess they could apply some to the UE too. 1. From what I remember from PT school, I was only supposed to floss if there WAS NOT an adhesion. The rationale was that it is too sensitive to floss something that is stuck and moving a nerve that is not adhered improves the trophic factors and may provide pain relief and nutrition, AS LONG AS it was a "slider" technique not a "tensioner" technique so it stayed in a pain free range and was not too many reps (rec. was up to 15 reps maybe 3 times a day). It makes sense to me not to stretch a sensitive nerve, but why not floss it (with slider technique). As far as an adhered nerve, wouldn't pulling on it just worsen irritation unless I first did something to release the adhesion (address the "container")? (maybe I am thinking of nerve adhesion and compression as the same thing). Maybe I was supposed to remove the compression (not the adhesion) first: in the case from the video that could be moving the person out of extension if neural tension testing is positive in extension but not positive in flexion (or in loaded and unloaded positions). Is anyone familiar with the line of thinking I remember from PT school? How does it fit into what you are teaching in the video? is it just wrong, outdated? am I understanding wrong? Personally, I have had back pain (no neural symptoms) that felt slightly better after nerve stretching and seemed to help with my overall recovery, but I was completely not irritable in my nerve (could feel strong tension but no pathologic/concordant symptoms in my leg). My back symptoms were like discogenic pain at the time. I am trying to make this experience fit with the education as well (and it leads into my next question). 2 Asymmetry and severity: It makes sense to me that asymmetry is important for diagnosis, but is there a guide on how to determine positive if the person seems limited bilaterally, or how much asymmetry is really relevant? Also do the symptoms have to be concordant? In the video it seems that any pulling or reduced ROM would be positive. I treat a lot of people with many problems, so that it can be hard to choose what is relevant. I have previously thought the symptoms should be concordant for it to be relevant (outside of severe ROM loss) to what I am trying to examine and address, not just any feeling of tension in the nerve. Is there a specific range of motion loss that is normal or abnormal (like how Doc Rog says it is normal to have end range tension in an adult)? I am also curious about natural mild asymmetries that humans often have that are not particularly relevant. I am concerned about over-pathologizing something just because it is a little different from one side to the next. For example, one of my hips adducts more than the other which does more ER than the first hip (I noticed it when practicing the side splits). This does not bother me in my daily life (except when I was trying to be a ballet dancer) but it seems pretty unchangeable. It is not a pathology, just how my body moves (and it is likely fixed skeletal variation regardless). I would not want my PT to be distracted by this when trying to help me. Likewise, I don't want to get distracted by a small variance in sides with neural tension tests if that could just be pretty normal for the person. How do you decide if the findings are relevant?
