Physical therapy, just on a very surface level could be considered an alternative type or natural treatment for certain conditions like back pain. Unlike aromatherapy, herbal remedies etc, physical therapy has been recognized as a legitimate treatment for many physical or bodily problems resulting from disease, accidents and other things that can affect our life.
It is different from Occupational therapy. Occupational therapists treat people who are considered to have much more permanent physical or developmental problems. The physical therapist however may be considered a shorter term solution for people in need of temporary assistance and treatments.
