Boyer Lab Seeks Subjects for Study of Knee Osteoarthritis

Researchers in assistant professor of kinesiology Katherine Boyer's lab are seeking adults age 50-75 in good general health who have osteoarthritis in at least one knee, can walk without assistive devices, and are able to walk on a treadmill for 20 minutes.

"We're investigating the relationship between exercise-induced pain associated with knee osteoarthritis and knee joint mechanics. We hope to learn more about how the body's motor system adapts to a painful stimuli to gain a better understand of the potential risks or benefits of treating pain and the potential for injury of uninvolved joints," Boyer said.

Participants will be asked to complete a four-hour visit during which researchers will collect data on the way they walk over ground and on a treadmill. Total walking time will be approximately 60 minutes, with rest breaks throughout the visit. Participants will also be asked to complete questionnaires about their health and knee pain. Individuals will receive $50 for taking part in the study.

"Those who take part will gain insight into their exercise tolerance with respect to the change in joint pain severity and the reduction of pain with a rest period. This may help participants plan with help from their physician a manageable exercise program," Boyer said.

Those who have received a joint injection within four weeks or made other similar changes to the management of osteoarthritis symptoms are not eligible for this study. If interested, contact the Boyer Biomechanics lab at or by calling 545-1717 or (269) 588-0226.
