If there's little knowledge or consensus then we should be cautiously optimistic about any perceived progress, we shouldn't run headlong into X fixes everything territory. It's important to keep in mind that we may not know why something works because that is also how science progresses, it's the motivation to continue refining a process or experiment until we have fully explained the method of action. Doing this often leads to important improvements in the method of application. The epitome of how science progresses is diligently applying the scientific method (repeatedly) and not fucking with the results to generate hype or feed a pet theory. The biggest news out of this is that stretching and exercise are still good for your health and you should do them more often. Massage probably won't hurt but if you have serious health problems you should probably still see a doctor.
