Introduction:
Whether there is the long-term effect of acupuncture on patients with knee osteoarthritis (KOA) or not is controversial. According to the basic theory of traditional acupuncture, deqi is the key to the efficacy of acupuncture. This randomized controlled trial aims to evaluate the existence of long-term effects caused by deqi in patients with KOA.
Methods And Analysis:
A three-armed, parallel-design, randomized controlled trial is underway in China.108 KOA patients recruited by the rehabilitation center of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine will be randomly assigned to the acupuncture with deqi group (A group), the acupuncture without deqi group (B group) and the waiting-list group (C group). Each patient will receive 5 30-minute sessions per week for 4 consecutive weeks and rest for 2 days between treatments, and undergo a 20-week follow-up. The primary outcome is the Western Ontario and McMaster Universities Osteoarthritis index (WOMAC score). The secondary outcomes include Western Ontario and McMaster Universities Osteoarthritis index (WOMAC score), Knee Injury and Osteoarthritis Outcome Score (KOOS), arthritis quality of life measurement scale simplified scale (AIMS2-SF), emotional monitoring and expectation scale. The pain visual analogue scale (VAS) and the Chinese version of modified Massachusetts General Hospital Acupuncture Sensation Scale (C-MMASS) will be used to evaluate the deqi sensation after each acupuncture treatment. At the same time, adverse events (AEs) occurred in the whole process will be recorded and analyzed. We will perform an intention-to-treat analysis and protocol (PP) analysis to statistically analyze the results of the trial.
Discussion:
This trial will be useful to study the long-term effect of acupuncture and the influence of the deqi sensation on the long-term in the treatment of KOA, and to provide a clinical basis for treatment of patients with mild to moderate knee osteoarthritis in clinic.
