What is the difference between an osteopath and a chiropractor?

The types of conditions that osteopaths and chiropractors treat are very similar. The main difference is that Osteopaths diagnose patients to have functional lesions; stiffness and immobility of joints, muscular spasm surrounding the joints causing pain, postural changes and irregular movements, whereas Chiropractors tend to focus on positional lesions of the vertebrae ie, bones out of place. Therefore you will generally find that Chiropractors use mainly manipulation during treatment whereas Osteopaths also combine soft tissue and articulation of joints as well as manipulation.
