Abstract

|
|
Objective : Acupuncture has been widely used throughout the world for the treatment of knee osteoarthritis (knee OA). This study investigated whether acupuncture, particularly Sa?am acupuncture, could be effective in relieving pain and improving the symptoms of knee OA.
Method : This study was conducted as a prospective, randomized, controlled, and patient? and investigator?blinded clinical trial. Forty volunteers with knee OA participated in the study. All participants were screened through an inclusion and exclusion criteria. Thirty four participants completed the clinical trial. In total, forty subjects were randomly selected to receive Sa?am acupuncture. Eight sessions of acupuncture were given at the contralateral side of the problematic knee for 4 weeks. Korean translation of Western Ontario and McMaster Universities Osteoarthritis Index (KWOMAC) scores were measured twice: at the beginning and end of the clinical trial period. Both the Patient Global Assessment and physical health scores based on the 36?Item Short?Form Health Survey were also used to measure the results.
Results : Compared to the pre?trial scores, the Sa?am acupuncture group (n=34) showed a significant decrease in KWOMAC total scores according to a paired t?test. The Sa?am acupuncture group also showed significant improvement in the Patient Global Assessment when compared to the pre?trial.
Conclusions : Sa?am acupuncture for knee OA resulted in an improved KWOMAC total score. This was mostly driven by the function component score that was greatly affected by acupuncture. However, further studies with expanded designs are needed to solidify this finding with scientific rigor.
