Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Keeping individuals with knee osteoarthritis physically active is critically important. Exercise is effective at reducing pain while improving physical function. However some exercises can overload the knee, and as a result, worsen knee pain and health of the knee joint. Yoga offers a foundation of static postures that improve muscle strength and joint flexibility. Using sophisticated technology that allows us to calculate the loads inside the knee, the investigators have selected yoga exercises that do not overload the knee joint. The investigators have designed a yoga exercise class that is ideal for people with knee osteoarthritis. The purpose of the study is to investigate whether these yoga exercises increase muscle strength and reduce knee pain in women with knee osteoarthritis. In addition, the investigators aim to show that these yoga exercises will also improve knee loads during activities, mobility and heart health. The investigators will ask 50 women with knee osteoarthritis to participate in a 12 week yoga exercise intervention, that requires attendance to 3 classes each week. The investigators will test strength of the leg muscles, pain, knee joint loads, mobility and cardiovascular health before and after the 12 week yoga exercise intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is an uncontrolled intervention study with repeated measures. The intervention is a 12-week supervised exercise class featuring biomechanically sound exercises for people with knee osteoarthritis. Measures of strength of the knee muscles, pain, biomechanics during walking and yoga, mobility and cardiovascular health will be included. Strength will be measured on a dynamometer. Pain will be assessed with questionnaires. Walking and three yoga postures will be observed using motion capture system integrated with force measurements from the floor. Mobility will be assessed during walking, stair-climbing and chair standing tasks. Cardiovascular health will be measured during a submaximal bicycle task.
