Abstract
BackgroundShoulder pain is an uncomfortable feeling in the muscle around the shoulder. The cause of myalgia is the accumulation of lactic acid in muscles and impaired blood circulation, which is called blood stasis in traditional East Asian medicine. This study aimed to explore the therapeutic effect of Gyejibongnyeong-Hwan (GBH) for shoulder discomfort related to blood stasis before and after treatment.Methods/designThis study will be a double-centre, randomised, wait-list controlled pilot trial. Participants with shoulder pain and with a visual analogue scale score of 4 or higher out of 10, blood stasis score of 9 or higher, and triglyceride level of ≥150 mg/dl or total cholesterol level of ≥200 mg/dl will be recruited from two university hospitals. A total of 40 participants will be assigned to the immediate and waiting treatment groups. The immediate treatment group will receive GBH for 8 weeks on enrolment while the waiting treatment group will receive GBH for 8–16 weeks after 8 weeks of controlled waiting. The primary outcome is shoulder pain, and the secondary outcomes are the blood stasis score, blood pressure, ankle–brachial pressure index, brachial–ankle pulse wave velocity, body mass index, waist circumference, indexes of oximetry, and levels of blood lipid, blood sugar, resistin, C-reactive protein, serum amyloid P, and D-dimer.DiscussionThe results of this pilot trial will be the bases for a full-scale clinical trial of GBH.Trial registrationClinical Research Information Service, KCT0003837.
