ObjectiveThe purpose of this preliminary study was to examine whether collateral meridian (CM) therapy was feasible in treating knee osteoarthritis (OA) pain.MethodsTwenty-eight patients with knee OA and knee pain were randomly allocated to 2 groups. The CM group patients received CM therapy, whereas the control patients received placebo treatment for knee pain relief. Patients in the CM group received 2 CM treatments weekly for 3 weeks. The outcome measures were pain intensity on a visual analog scale, and knee function was determined using the Western Ontario and McMaster Universities Osteoarthritis Index.ResultsIn the CM group, the posttreatment visual analog scale and Western Ontario and McMaster Universities Osteoarthritis Index scores were lower than those of the control group; a significant reduction in pain intensity (P = .02, P = .01, respectively) and improvement in knee function (P = .04, P = .03, respectively) were shown in the CM group at the second and third week.ConclusionCollateral meridian therapy may be feasible and effective for knee OA pain relief and knee function recovery. Therefore, additional randomized control trials are warranted.Copyright © 2013 National University of Health Sciences. Published by Mosby, Inc. All rights reserved.
