I would say that All Chiropractic practitioner ought to
1. Be expert in handling dislocation of other bodily joints.
2. Show in their office, the number of dislocation treatment he has successfully treated.
Chiropractic handles your spine with care.
So do a normal qualified medical doctor.
So why do we need a Chiropractic? Chiropractic must have a value-add.
As far as I know, normal medical doctor may be good at diagnosis and prescribing a proper medication. But I bet, they are, poor in handling a simple dislocation of joints. My encounter was that the doctor don't even bothered to treat my dislocation in my wrist. He just asked the nurses to do it. And they did not succeed despite many painful and feeble attempts. I think the doctor would do no better. In my case, a "famous" chinese joint dislocation specialist in old china town did the job. Quick, fast, single-handedly, confidence inspiring. I guess he do many cases every hour until he is quite skilled.
I think making it a mandatory requirement for Chiropractic to handle common limbs dislocation is good for the following reasons:
1. They fill a gap the normal doctors are poor in.
2. They get lots of practices, treating dislocation.
3. If they cannot even put back a simple dislocated arm, properly, painlessly, and confidently, all their customer will shy away from asking him to handle their spine.
4. If he is unpopular in treating normal dislocation of arm and leg joints, his certification should be reevaluated. If he is unable to handle joint dislocation, his knowledge about the spine is "useless". This is because normal doctor would be better positioned to handle it.
5.There would be more and more people doing high quality dislocation treatement.
6. More People will go to "chiropractor" for simple, basic once off dislocation treatment.
7. If the customer wishes to pay extra for daily message to aid the healing of a broken bone, it is up to them. At least we know that they are paying extra to a person who is an expert dislocation specialist.
