Objectifying Specific and Nonspecific Effects of Acupuncture: A Double-Blinded Randomised Trial in Osteoarthritis of the Knee

Figure 3

WOMAC pain scores before and after acupuncture. The figure compares the WOMAC pain scores for classical acupuncture, semistandardised modern acupuncture, and non-specific needling. Pain was assessed immediately prior to acupuncture, directly thereafter, by self-administered questionnaire at home at 3 days after acupuncture, and at a recall visit after 7 days. Data display the means adjusted for Kellgren classification, prior intake of medication, and patient gender. Error bars indicate the standard error of the mean.
