Can adjustments be done by a medical doctor, physical therapist or massage therapist?
No! (much emphasis added!) The above named people are perhaps well trained in their respective fields but not one of them has training in chiropractic philosophy, science or art. Of course if they went to chiropractic school that’s a different situation. Never allow anyone who is not a certified Doctor of Chiropractic in any way crack, pop or adjust you! You can be seriously injured.
