I joined this community because I had seen this question and felt able to answer it. However even though I had a textbook on martial arts vital points to hand AND had used the methods from the book before to treat the kind of pain/stiffness described in the question, it seems to have attracted negative attention as I am unable to quote clinical trials of this method.
After answering one or two other questions and meeting similar if not worse negative response. I am starting to think that this community has a problem.
If only truly evidence based answers are accepted by the community as objective (and by this I mean quantitatively analysed video footage or reference to textbooks or equivalent) how can any questions get asked or answered? In other words how can this community function? There isn't enough evidence to really know what works when trained people fight the untrained. Let alone some kind of theoretical street fight between people who would obviously know better.
Martial arts are essentially an aural tradition in that you can only learn them from other people who know them. Much like folk stories.
If I asked a question on here about something as simple as how to punch correctly I am sure I would get many conflicting answers each based on a different style. We cant run trials about the effectiveness of different strikes to the cause damage. no one would agree to get punched for science.
In other words I can't think of any question that could be answered in the manner stack exchange seems to require. I think some people more senior than myself in the community need to discuss what direction they are going to take this site to make it more useful and accessible.
