In Canada, acupuncture is a regulated medical practice that involves inserting thin needles at specific points on the body to alleviate pain and other health conditions. Acupuncture is a controlled act in physiotherapy practice. Therefore, physiotherapists who incorporate acupuncture into their practice should have the necessary education and roster this controlled act with the regulatory college in their province. Although acupuncture can be helpful, potential complications can arise, ranging from minor bruising to life-threatening conditions such as pneumothorax and cardiac tamponade. This article provides information on the potential adverse effects of acupuncture and provides recommendations for physiotherapists regarding prevention and management of any incidents that may arise during treatment.
