No doubt that you're referring to applied kinesiology and NOT kinesiology.
Because kinesiology is actually very sound medical science.
Even if a physical therapist is not a kinesiologist, they apply kinesiology to their actions. Being a strict kinesiologist, though, is not the same as a physical therapist.
So, back to what you probably meant (you should request that the mods modify your thread title), applied kinesiology...
It should be quite obvious that it is quackery. The "positive" from patients on this are almost completely anecdotal and are really just the placebo effect. There are plenty of empirical studies done that more than prove that AK is quackery.
