Researchers in the Multidimensional Intervention for Early Osteoarthritis of the Knee study say that strength training regimens, self-management programs, or both, could help physically inactive middle-aged people with symptomatic osteoarthritis .
Osteoarthritis (OA) is the most common form of arthritis.
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 hypothesized that combining the 2 treatments might enhance the outcomes," said Patrick McKnight, lead author of the Knee Study.
The Knee Study, conducted at the University of Arizona Arthritis Center in Tucson, AZ, was a 24-month unblinded, randomized intervention trial to compare the effects of strength training programs, self-management programs, and a combination of both.
The 273 study participants were between the ages of 35 and 65 years, reported pain and disability due to knee pain on most days in one or both knees for a period of no more than 5 years, and had Kellgren/Lawrence classification grade 2 radiographic evidence of knee OA in one or both knees.
