Objectives
Narrative objectives1
Endogenous analgesic system plays an important role when the excessive pain is applied to the body. It involves descending pain inhibitory system and endogenous opioid. Dysfunction of the endogenous analgesic system causes chronic pain. Low back pain has a large number of affected patients, so establishment of appropriate low back pain treatment is required. It has been reported that the function of the endogenous analgesic system is decreased in various chronic pain patients including chronic arthralgia (Lewis et al., J Pain 2012; 10: 936-44.). In these cases, the medicine that activates the endogenous analgesic system is considered to be suitable as a treatment. However, there have been no reports that evaluate the function of the endogenous analgesic system of patients with chronic low back pain. In this study, we will evaluate the function of endogenous analgesic system of chronic low back pain patients. If the dysfunction of endogenous analgesic system is revealed, new evidence-based therapies can be established.
