That’s a reasonable assumption, since a lot of them do it. That’s been part of how they’ve achieved so much legitimacy- they’ve gradually folded in more and more evidence-based practices over the decades. Massage Therapy is a big one, and some of them do legitimate nutrition counseling or even Physiotherapy as well.
However the core of the business is still the “cracking” thing they do, which is total nonsense. The problem is that the legitimate stuff muddies the waters. You might go in and get legitimate massage therapy for a sore shoulder, but then get sold on “electrical muscle stimulation” or a bunch of herbal supplements. When the legit is mixed with the nonsense, average folk can’t be expected to tell the difference. This is what makes them dangerous. If they simply didn’t exist and all those other legit disciplines remained doing what they do, the world would be a better place.
