During a session, you will be asked to remove any jewellery or metal objects. The physiotherapist will then attach electrodes to the skin. The electrodes will send electrical impulses to the body. You may feel a tingling sensation or a slight buzzing sensation. You should not feel any pain. If you do, let the physiotherapist know. You will then be asked to relax and let the machine do its work. You may be asked to exercise or move around during the session.
