Acupuncture is a very safe treatment with little or no side effects. However, certain people should be cautious. People with pacemakers for example, should not have electrical stimulation. Women in early pregnancy and haemophiliacs should consult their doctor before embarking on acupuncture treatment. If you are considering acupuncture, get a referral to a trained practitioner.
Acupressure is a variation of acupuncture.
Shiatsu, also related, involves deep massage. Literally translated, shiatsu is Japanese for finger pressure. A therapist applies sustained pressure, primarily with the thumbs, to selected points. He or she may also use their palms, elbows and occasionally the knees. In some provinces, shiatsu therapists are certified, designating them as members of a professional association.
