Postmenopausal women with breast cancer whose treatment generally includes an aromatase inhibitor, or AI, often experience joint pain or stiffness known as AI-associated arthralgia. An estimated 20 to 32 percent of these women stop taking their AI due to this side effect. Researchers at the University of North Carolina at Chapel Hill conducted a pilot study to assess the potential positive effects of physical activity on joint pain and stiffness in these patients, as a potential alternative or adjunctive approach to arthralgia management that would enable them to continue their cancer therapy while living as pain- free as possible. "We were interested in seeing if a physical activity program that is evidence-based for reducing joint pain, stiffness and fatigue in adults with arthritis might have similar benefits for women experiencing AI- associated arthralgia," says Kirsten A…
