When a patient goes to the MD and ends up needing physical therapy, all that the MD does is order PT. They do not do extensive testing on patients they simply send orders to a PT to 'eval and treat.' Granted MDs have a more knowledge in disease processes, PTs also have knowledge. Furthermore, PTs are experts in musculoskeletal disorders. PTs know when the issue that a patient is presenting with is not PT treatable and will refer out. On a side not, how is it that if we are the experts in the field of musculoskeletal disorders that chiropractors, dentist, and podiatrist can refer to PT? By allowing these professions to refer to PT, the law is stating that it is not necessary to hold an MD to refer to physical therapy. Correct me if I am wrong, but do these professions have more knowledge in disease processes than physical therapists? Also, massage therapist see patients directly. More often than not these patients are getting a massage to alleviate 'aches and pains'. Is their education substantial enough to know whether the pain the patient is experiencing renal disease, ovarian cancer, etc.?
