What is the difference between a chiropractor and a physiotherapist?

While both professions treat musculoskeletal conditions, only a chiropractor is a doctor allowing him/her to diagnose and treat the condition. A physiotherapist is able to use many modalities like ultrasound and interferential current. A chiropractor can use all these modalities as well as be able to perform manipulation of the joints when necessary. The physiotherapist may perform limited adjustments if they have some extra training.
