Many times one symptom can relate to tons of different problems a person could possibly have. For instance, a patient coming in after a car accident with back and neck pain, could be suffering from whiplash, a ruptured disk, a broken vertebrae, or many other things. The therapist has to be able to look at the whole situation and determine the problem. To do this they have to have knowledge of how all of the neck and back muscles and bones work together. Physical therapists have to be very competent in their work so they are helping people and not having them do things that will make it worse.
Physical therapy is a very dedicated job field.
One must be hard working, compassionate, and competent to be successful in this field of medicine. A person with these qualities will go far in physical therapy.
