Does Changes in the Electrical Resistance of an Acupuncture Meridian Predict Pain Intensity Following Orthopedic Surgery?

Abstract: BackgroundSeveral methods for assessment of severity of pain have been proposed but all of them are subjective.ObjectivesThis study evaluated the association concerning changes in electrical resistance (ER) between two acupuncture points and severity of postoperative pain in order to define an objective measurement of pain.Patients and MethodsIn a cross-sectional study, 50 patients undergoing lower extremity orthopedic surgery with postoperative moderate to severe pain (VAS > 4,) were consecutively enrolled. I… Show more

“…However, since there were no significant different changes in ESR imbalance ratio as well as raw ESR value between PD patients and healthy women, changes in ESR of acupuncture points did not reflect menstrual pain according to this study. Our result was similar to another study, which also showed that there was no significant association between pain intensity and change in ESR of acupuncture meridians [ 39 ].…”

“…The mechanism of acupuncture is not fully clarified yet and different mechanisms have been proposed. Some studies revealed that acupuncture could stimulate different types of afferent fibers, which cause inhibition in pain transmission within the central nervous system (10, 11). It also eases the release of some pain suppressors including opiate chemical substances (such as endorphin), serotonin, dopamine, neurotrophins, and nitric oxide in the central nervous system (9).…”

“…In addition, studies conducted using functional MRI have concluded that acupuncture effects are linked to specific regions of the brain and their placement impacts important brain structures and function (59). Different methods for acupuncture have been tested; clinical trials have shown efficacy in many fields, including chronic back pain, headache, and recovery time from general anesthesia (56,(60)(61)(62)(63)(64).…”
