How is that misleading? I'm summing up the latest research. Childs and Fritz defined 5 CPR's for manip. I.e the more of the following symptoms, the better they will respond to no more that THREE (3) trials of manipulation. The Clinical Predication Rules for SMT include:
1) Pain <16 days
2) Hip IR >35 degrees of at least one hip
3) No symtoms distal to the knee
4) Fear Avoidance belefs questionaire (FABQ) score <19
5) Lumbar segmental hypomobility as judged by a PA of a spinous process (this last one is debatable because the inter and intra-rater validity of palpation is poor at best)
patients who present with 4/5 of these symptoms the patient has a 92% success rate with manipulation....problem is, a great number of chiro patients do not fit the aforementioned criteria and thus would not respond as favourably to manipulation...especially the 3X a week for the rest of your life some chiros like to prescribe! Don't get me started on the whole "the onus is on the patient to get better" idea that some chiros refuse to acknowledge...they make patients passive bystanders in their own healthcare.
Basically, SOOO many chiros manip every patient that comes into their office...that, in my opinion, is unethical. There are MANY more patients that would benefit much more from say deep core stabilizer exercises (TrA, pelvic floor, multifidus etc). So yes, i did generalize and i know there are some fantastic evidenced based chiros out there but from my experience, they are far and few between... and trust me, i have plenty of chiro-related experiences!
