Chiropractic removes stress to the nervous system by delivering specific chiropractic adjustments. Chiropractic does not treat symptoms, rather it aims to take the stress off the body so the body can heal itself.
On the other hand, Physiotherapy treats symptoms with exercises and other physical treatments and fits in with the medical model. It is especially helpful with rehabilitation after accidents, surgery or other minor injuries. They do not adjust!
Osteopathy is a system of diagnosis and treatment, usually by manipulation, that mainly focuses on musculo-skeletal problems to enhance blood supply activity, thereby resolving mechanical problems of the body. It is more similar to chiropractic, however techniques, philosophy and intentions are different.
Chiropractors are very specific about which joint complex they are adjusting to remove stress, instead of looking generally to improve blood flow, like an Osteopath. The intention is also different. The nervous system supplies the musculo-skeletal system by enhancing the nervous system function, so chiropractic usually corrects the musculo-skeletal dysfunction. So the intention is once again with allowing the nervous system to function optimally.
Chiropractic is effective for achieving and maintaining optimal health, reducing pain and other symptoms of the body malfunctioning; as well as general injury prevention and improved injury recovery, especially in sport and enhanced physical performance.
