Objectives : This study was designed to estimate the effects of BU herbal acupuncture theraphy on low back pain of sprain patients by using Visual Analogue Scale(VAS) and pressure algometer. Methods : 13 volunteers were applied to BU herbal acupuncture stimulation on the BL23, BL24, BL25 and BL26 acupoints. The degree of improvement of low back pain of sprain was evaluated by VAS and pain pressure threshold(at the points of BL23 and BL24 before treatment, before 3rd treatment(after herbal acupuncture). Results : In VAS scores, there were significant differences between before and after herbal acupuncture stimulation. But there was no significant difference between before and after herbal acupuncture stimulation in pain threshold. Conclusions : The effectiveness of BU herbal acupuncture theraphy on low back pain of sprain was shown through VAS and pressure algometer. These imply that BU herbal acupuncture theraphy may be useful for low back pain of sprain. Further study is needed about BU herbal acupuncture.
