Acupuncture fails to hit the mark for chronic knee pain By Lucy Piper, Senior medwireNews Reporter Research findings do not support the use of needle or laser acupuncture for treating chronic knee discomfort in patients over the age of 50 years. The findings support suggestions by The American Academy of Orthopaedic Surgeons and the National Institute for Health and Care Excellence against the use of acupuncture for knee osteoarthritis. For the study, which followed a Zelen design, 282 people, aged at least 50 years, volunteered to be observed for a full year. They were then randomly assigned to receive no acupuncture, needle acupuncture, laser acupuncture or sham laser beam acupuncture. Consent for the methods was sought after randomisation to be able to minimise the positive effects of sufferers knowingly volunteering for an acupuncture trial.For the per-protocol analyses, all sufferers who underwent randomization, got the assigned study stent implanted, and experienced 1-12 months follow-up data available were included. Relative risk and risks variations were calculated for the principal end point, and 95 percent confidence intervals were built.05. For tests the superiority of the everolimus-eluting stent to the paclitaxel-eluting stent, a two-sided alpha level of 0.05 was used. Hazard ratios and the corresponding 95 percent confidence intervals were also calculated. The consistency of treatment effects in prespecified subgroups was assessed with the use of logistic regression with exams for conversation. All statistical analyses were performed with the use of SAS software, version 9.3 .
