Impact of Different Resistance Training Protocols on Pain in Knee Osteoarthritis

This study aim to evaluate pain after different resistance training protocols (placebo, 4 sets of 10RM, 8 sets of 10 RM and 12 sets of 10RM) in patients with severe knee osteoarthritis.

Inclusion Criteria:

• men and women at least 55 years old
• diagnosed with severe knee OA

• another hip or knee joint replacement in the previous year
• any medical condition in which exercise was contraindicated
• participated in exercise programs (>2 days/week, training at intensities of 10-15RM) in the 6 months prior to the study
• history of stroke, brain surgery, major depression, or any self-perceived cognitive alterations that could affect the performance of study tasks
