Despite the increasing utilization of pharmacopuncture therapy, there is still a lack of high-quality research to support its effectiveness. This pilot study aimed to assess the feasibility of pharmacopuncture therapy adjuvant to acupuncture treatment for rotator cuff disease.Patients and Methods: This was a parallel-grouped, pragmatic randomized controlled, pilot study. Forty patients were randomly allocated to either the experimental or the control group. All patients received acupuncture treatment for four weeks, and pharmacopuncture was additionally administered to the experimental group. After eight treatments were delivered over four weeks, follow-up assessments were performed. The primary outcome was the mean change in the visual analog scale (VAS) score for shoulder pain from baseline to visit 8. Secondary outcomes included shoulder pain and disability index (SPADI) at visits 4, 8, and 9, shoulder range of motion (ROM) at visits 4, 8, and 9, EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L) at visits 8 and 9, patient global impression of change (PGIC) at visits 8 and 9, and mean rescue medication consumption at visits 8 and 9.Results: Both groups showed that each treatment effectively improved rotator cuff disease in most assessments. Particularly, the group that received acupuncture plus pharmacopuncture required fewer rescue medications than the group that received acupuncture alone. However, there was little statistically significant difference between the two groups. There were no serious adverse events experienced by patients in this study.Conclusion: Although there was little statistical difference between the two groups, the combination of acupuncture and pharmacopuncture for rotator cuff disease was associated with a reduction in the rescue medicine dosage compared with acupuncture alone. Also, it confirmed the safety of pharmacopuncture therapy. This pilot study would help design future research on the effectiveness of pharmacopuncture in rotator cuff disease.Keywords: rotator cuff disease, pharmacopuncture, acupuncture, pragmatic trial, randomized controlled trial
