This paper is better than the video.

The "methods" section basically says that the model proposed was derived from some Google searches.

I know!
Even so, there are fucking tons of these videos of this shit happening.

I'm sure there's no scientific basis for this stuff but it doesn't mean it doesn't actually make people feel better or in less pain, for whatever reason. Chiropractics is a TOTAL sham but insurance companies often pay for it because it makes people feel better. The anecdotal evidence you post (the original link to that blog post is dead) is about as convincing as this:

See outrage in the comments.

I would just like to point out there is such a thing as medical massage. Not everyone who practices massage is a quack.

This is simply a technique for (allegedly) simulating the effect given by a practitioner. I read a little about it, and it is apparently an acquired skill.
