Objectives : The purpose of this study was to examine whether or not Postural Yinyang Correction of TMJ(Temporomandibular joint) using Standard Intraoral Appliance could decrease Chronic Low Back Pain.

Methods : Clinical studies were reviewed the medical records of 40 patients who were treated in Chronic Low Back Pain from the Dept. of Acupuncture and Moxibustion, performed at Dongeui University from November 1st, 2015 to June 5th, 2016. The patients were divided into 2 groups: an experimental group(Group A, n=20), and a control group(Group B, n=20). In the experimental group(Group A), we treated the patients with acupuncture, Sweet Bee Venom Treatment and FCST (Functional Cerebrospinal Therapy) through Standard Intraoral Appliance from ABA(Accurate Balancing Appliance), Full Body Exercise Therapy, and Upper Cervical Alignment Balance Therapy. In the control group (Group B), we treated the patients with acupuncture and Sweet Bee Venom Treatment.
1. To estimate the efficacy in controlling pain, we analyzed the Visual Analog Scale (VAS).
2. To evaluate functional change of patients, we analyzed the Oswestry Low Back Disability Questionnaire (ODI).

Results : In both groups, VAS and ODI decreased significantly.
1. In the VAS, the result of the experimental group (Group A) is significantly more effective than that of control group (Group B).
2. In the ODI, the result of the experimental group (Group A) is statistically less effective compared to that of the control group (Group B), but not significantly.

Conclusion : According to the results, Postural Yinyang Correction of TMJ using Standard Intraoral Appliance may be effective treatment for Low Back Pain.
