Newswise — DURHAM, N.C. -- Patients with arthritis in their knees experienced significant improvement in pain and mobility after undergoing a weekly, whole-body massage for two months, according to a study led by researchers at Duke Health.
The finding, appearing online in the Journal of General Internal Medicine, suggests that massage could offer a safe and effective complement to the management of knee osteoarthritis, at least in the short term.
“Osteoarthritis is a leading cause of disability and affects more than 30 million people in America,” said lead author Adam Perlman, M.D., program director of the Leadership Program in Integrative Healthcare at Duke University School of Medicine. “Medications are available, but many patients experience adverse side effects, raising the need for alternatives. This study demonstrates that massage has potential to be one such option.”
Perlman and colleagues at four institutions enrolled approximately 200 patients with osteoarthritis in their knees. Patients were randomly divided into three groups: those who received a one-hour, weekly Swedish massage for eight weeks; those who received a light-touch control treatment; and those who received no extra care other than their usual regimen.
After eight weeks, each of the groups were again randomized to continue with massage or light-touch every other week, or to receive no treatment for the remainder of the study, which spanned 52 weeks.
Patients were assessed every two months using a standardized questionnaire called the Western Ontario and McMaster Universities Osteoarthritis Index. The questioinnaire measures pain, stiffness and functional limitations, including how well patients can climb stairs, stand up from sitting or lying down, bend, walk or get out of a car, among other activities.
At eight weeks, massage significantly improved patients’ scores on the questionnaire compared to light-touch and usual care. Massage improved pain, stiffness, and physical function.
At 52 weeks, the twice-monthly massages maintained the improvements observed at eight weeks, but did not provide an additional benefit. There were no significant differences between the groups at 52 weeks.
“Massage therapy is one of the most popular complementary medicine interventions,” Perlman said. “At a time when people are looking for effective non-medication options for pain, this study provides further evidence that massage has a potential role, at least for those suffering with osteoarthritis.”
In addition to Perlman, study authors include Susan Gould Fogerite, Oliver Glass, Elizabeth Bechard, Ather Ali, Valentine Y. Njike, Carl Pieper, Natalia O. Dmitrieva, Alison Luciano, Lisa Rosenberger, Teresa Keever, Carl Milak, Eric A. Finkelstein, Gwendolyn Mahon, Giovanni Campanile, Ann Cotter and David L. Katz.
The study received funding the National Center for Complementary and Integrative Health (NCCIH), part of the National Institutes of Health (R01AT004623).
