Acupuncture Analgesia: Analgesia produced by the insertion of ACUPUNCTURE needles at certain ACUPUNCTURE POINTS on the body. This activates small myelinated nerve fibers in the muscle which transmit impulses to the spinal cord and then activate three centers - the spinal cord, midbrain and pituitary/hypothalamus - to produce analgesia.Acupuncture Therapy: Treatment of disease by inserting needles along specific pathways or meridians. The placement varies with the disease being treated. It is sometimes used in conjunction with heat, moxibustion, acupressure, or electric stimulation.Acupuncture Points: Designated locations along nerves or organ meridians for inserting acupuncture needles.Analgesia: Methods of PAIN relief that may be used with or in place of ANALGESICS.Acupuncture: The occupational discipline of the traditional Chinese methods of ACUPUNCTURE THERAPY for treating disease by inserting needles along specific pathways or meridians.Analgesia, Epidural: The relief of pain without loss of consciousness through the introduction of an analgesic agent into the epidural space of the vertebral canal. It is differentiated from ANESTHESIA, EPIDURAL which refers to the state of insensitivity to sensation.Analgesia, Obstetrical: The elimination of PAIN, without the loss of CONSCIOUSNESS, during OBSTETRIC LABOR; OBSTETRIC DELIVERY; or the POSTPARTUM PERIOD, usually through the administration of ANALGESICS.Acupuncture, Ear: Acupuncture therapy by inserting needles in the ear. It is used to control pain and for treating various ailments.Analgesia, Patient-Controlled: Relief of PAIN, without loss of CONSCIOUSNESS, through ANALGESIC AGENTS administered by the patients. It has been used successfully to control POSTOPERATIVE PAIN, during OBSTETRIC LABOR, after BURNS, and in TERMINAL CARE. The choice of agent, dose, and lockout interval greatly influence effectiveness. The potential for overdose can be minimized by combining small bolus doses with a mandatory interval between successive doses (lockout interval).Analgesics, Opioid: Compounds with activity like OPIATE ALKALOIDS, acting at OPIOID RECEPTORS. Properties include induction of ANALGESIA or NARCOSIS.Electroacupuncture: A form of acupuncture with electrical impulses passing through the needles to stimulate NERVE TISSUE. It can be used for ANALGESIA; ANESTHESIA; REHABILITATION; and treatment for diseases.Moxibustion: The burning of a small, thimble sized, smoldering plug of dried leaves on the SKIN at an ACUPUNCTURE point. Usually the plugs contain leaves of MUGWORT or moxa.Pain Measurement: Scales, questionnaires, tests, and other methods used to assess pain severity and duration in patients or experimental animals to aid in diagnosis, therapy, and physiological studies.Meridians: Classical loci in ACUPUNCTURE. They are main and collateral channels, regarded as a network of passages, through which vital energy (Qi) circulates and along which acupoints (ACUPUNCTURE POINTS) are distributed. The meridians are a series of 14 lines upon which more than 400 acupoints are located on the body.
