Blood Stasis Therapy for Traumatic Injury: A Prospective, Single-Arm, Pre-Post Pilot Study.

Objectives: Blood stasis is an important pathophysiologic concept in Traditional East Asian Medicine. It has been considered to be a pathogenic factor in chronic and incurable conditions such as pain, infertility, cancer, coronary heart disease, and others. The aim of this study was to investigate the effects of pain reduction by blood stasis treatment for blood stasis syndromes with traumatic injury.

Methods: A single-center prospective pretest-post-test pilot study included 73 patients with a trauma that occurred within the past 2 weeks who were admitted into Jaseng Hospital of Korean Medicine from August 2015 through December 2015. Of the 50 patients analyzed in this study, 42 were women (mean age, 33.52). Triple Energizer-reinforcing Saam acupuncture set, herbal medicine (Dangkwisoo-san), and wet cupping on tender point, which are Korean medical therapies generally executed to treat post-traumatic pain, were performed. The patients had to receive at least six sessions of treatment during the 2 weeks, with subsequent treatment being performed within 3 ± 1 days after the previous treatment. Numeric rating scale (NRS) score and general pain severity indicator was measured as a primary outcome measure. The blood stasis questionnaire, oximetry, and patient's satisfaction were also measured.

Results: The mean size of subcutaneous bleeding (width and length) and NRS score as a general pain indicator significantly decreased over the visits (all p < 0.01, visit 1 vs. visit 6). Among the blood stasis symptoms in the questionnaire, 11 blood stasis indicators significantly decreased (all p < 0.05). The patients showed significant improvement in the minimum and maximum value of peripheral perfusion index after the treatment (p = 0.011 and p = 0.15, respectively).

Conclusions: This study reveals that blood stasis treatment may help improve the pain of patients with traumatic injury by enhancing the peripheral blood flow. The significant results observed in this study support some evidence of the theories of diagnosing blood stasis pattern and treatments of that pattern in Korean Medicine.
