A chiropractor has an expansive diagnostic education, while a physical therapist has a therapeutic, or intervention-based education. Although a chiropractor can provide rehabilitative exercise and modality treatments to the client, his/her main type of treatment is spine manipulation.
A physical therapist may also provide manual therapy-type techniques to their patients, but activity modification, therapeutic exercise and modalities are the foundation and focus of a physical therapy practice.
