Study protocol for clinical trial to Compare the Effectiveness of 'Individualized Acupuncture' with 'Standardized Acupuncture' in Korean patients with Knee Osteoarthritis

Background : One of the characteristics of acupuncture, a popular modality for treating musculoskeletal pain, is a plurality in diagnosis and treatment that can profoundly influence the treatment outcome. This multiplicity in treatment modality has to be considered in any research on the effectiveness of acupuncture. Many practitioners stress the necessity for individualized patient treatment, including acupuncture point selection and manipulation technique. However, the importance of individualization in acupuncture treatment, compared with standardization, has received little attention in clinical trials. The aim of the future study described here is therefore to compare the effectiveness of individualized acupuncture for knee osteoarthritis with standardized acupuncture and no acupuncture in patients with knee osteoarthritis. Methods : A total of 195 patients aged 50 years and over with knee pain, will be randomly divided into three treatment groups: individualized acupuncture, standardized acupuncture, and waiting list. Outcome data will be collected through patient.completed questionnaires before randomization, and at 4, 8 and 12 weeks after randomization. The questionnaires will be investigated demographic details as well as information on pain, movement and function of the affected knee, general health and quality of life. Discussion : This paper presents details on the rationale, design, and methods of the trial.
