I have not taken the survey yet, and here is why: I would like to know if you ask specific two questions on this survey, which I cant check because it only shows you one of four pages before you can continue (a feature I think was poorly thought out, as we should be able to see the whole survey in order to ask questions about it before answering). This doesnt mean I dont appreciate the hard work! Here are the two questions I believe need to be on this survey, and I will explain why if they are not:
1) Do you have an overbite?
2) Have you had chronic neck pain or neck muscle strain since puberty?
I do apologize for not bringing this up before in regards to the creation of this survey, which is lazy on my part. Now here is why I think it should be on the survey if it is not, especially in regards to this specific research study:
This research study is targeting the vaso-vagal response, which is a function controlled in part by stimulai received by the vagus nerve. The vagus nerve travels through the neck, where constriction of the nerve is known to occurr but is a rarely diagnosed condition that can affect the stimulai reveived by said nerve. Constriction of major branches of this nerve can also occurr in lower areas within the body, but are also much more rare, and even far rarer still to show up in diagnosis. Current testing has a hard time showing whether the vagus nerve constriction is a problem (nerve conduction study?). Anyways I know you cant ask questions covering every little thing, but I think this one has huge implications for ruling out a significant possible cause.
The reason for the first questiobn, is that unadressed overbites can also cause neck problems severe enough to cause permanent muscle tension and spinal misalignment, and therefore maybe the vagus nerve as well.
If the questions arent included on the survey, I will answer it in the section "List any other medical conditions that you think might be important" which I am positive you must have included on the survey. But I at least wanted to bring it up in hopes that if it ISNT included, people will voluntarily answer them in said section.
