| |  Strength Training, Self-Management Improve Outcomes for Knee Osteoarthritis HOBOKEN, NJ -- January 5, 2010 -- Researchers participating in the Multidimensional Intervention for Early Osteoarthritis of the Knee (Knee Study) determined that physically inactive, middle-aged people with symptomatic osteoarthritis benefitted equally from strength training regimens, self-management programs, or a combination of the two. Details of this study are published in the January 2010 issue of Arthritis Care & Research. A number of studies have compared strength training protocols with self-management programs in older patient populations, but few have examined the potential benefit of using both approaches in conjunction. “We hypothesised that combining the 2 treatments might enhance the outcomes,” said lead author Patrick McKnight, University of Arizona Arthritis Center, Tucson, Arizona. The Knee Study was a 24-month unblinded, randomised intervention trial to compare the effects of strength training programs, self-management programs, and a combination of both. The 273 study participants were aged 35 to 65 years, reported pain and disability due to knee pain on most days in 1 or both knees for a period of no more than 5 years, and had Kellgren/Lawrence classification grade 2 radiographic evidence of knee osteoarthritis (OA) in 1 or both knees. Patients were randomly assigned to 1 of 3 treatment groups. The strength training group engaged in a 9-month initial phase designed to improve the core areas of stretching and balance, range of motion and flexibility, and isotonic muscle strength. The second, 15-month phase of this group concentrated on developing independent, long-term exercise habits. The second study group participated in a 2-phase self-management program designed to educate participants and provide one-on-one treatment advice. The combined group participated in both the complete strength training and self-management programs. A total of 201 out of 273 participants completed the 2-year trial, with the self-management group achieving the highest compliance rates. The study team set out to demonstrate that a combination of OA treatment programs would prove most effective, however, the study failed to uncover significant differences in results among the 3 study participant groups. All 3 groups demonstrated improvements in physical function tests and decreased self-reported pain and disability. “The logic behind the combined treatment was that the different factors addressed in physical and psychological treatments might produce an additive effect if administered together,” said Dr. McKnight. “These results suggest otherwise. Instead, the comparison of the 3 treatment arms showed no difference, suggesting similar benefits for all 3 over a 2-year period.” Given the higher rate of compliance in the self-management group, the Knee Study researchers suggest that self-management may be a less intrusive and equally effective early treatment for knee OA.
