Bodywork is an umbrella term for the many techniques, both ancient and modern, that promote relaxation and treatment of ailments (especially those of the musculoskeletal system.) through lessons in proper movement, postural re–education, exercise, massage and other forms of bodily manipulation. Some types of bodywork – including massage, qigong, reflexology, shiatsu and t’ai chi–can be practiced at home. Others may require the guidance of a trained professional.
