My anecdotal experience has been similar. The orthopedist I occasioanlly go to use chiropractic methods only sometimes. Other times he just tells me to take some pain medicine and to rest. Besides, I don't have back pain often anyway (luckily).
edit: Just to clarify, there is no scientific evidence that chiro is effective as anything other than placebo. All evidence provided is anecdotal and hence useless.
I say this as a long time skeptic of chiropractic; my dad, in fact, had a terrible moment in his youth where he had lower body paralysis for 2 days after a chirp visit... My partner has ahhh unusual wrist physiology and when we moved to a new city (near where she grew up), she wanted to go visit her old chiropractor to get her wrist looked at (the same guy had looked at it 30 years ago). I bit my tongue and didn't say anything. His advice: you need to get X-rays and I'll schedule you to see a (mainstream MD) specialist.
I'm still skeptical, but it gives me a little faith that in spite of whatever quackery exists, some of them do at least recognize problems that are the domain of conventional medicine.

The weakness of heuristics is that they don't turn into reusable models but vice versa models can leave you blind. The constant disdain for heuristics is a huge weakness of many scientifically minded people IMO.
this the silliest misinterpretation of Fourier analysis I've ever seen and I'm not going to try refute it except to say that with the clarity you're implying Fourier decomposition applies only to periodic signals (ie saying that a signal that has a continuous time FT "has most of its information expressed as a sine wave would be an egregious exaggeration so you must talking about series expansion and that only applies to periodic signals [and I'm at a loss for how to interpret info about chiropractors as periodic]).
