Experimental: Yoga For Knee Osteoarthritis
An tailored arthritis-specific yoga program for women with knee osteoarthritis with the aim of increasing leg strength and alleviating knee pain related to the disease.
Other: Yoga For Knee Osteoarthritis
Yoga program specifically for women with knee osteoarthritis.
- Change in Knee Extensor Torque [ Time Frame: Week 1 and Week 13 ]Knee extensor torque (Newton*meter) is calculated on a Biodex dynamometer using an isometric protocol. Trials are completed as a voluntary maximum effort.
- Change in Knee Pain [ Time Frame: Week 1 and Week 13 ]Knee pain is assessed subjectively via the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Intermittent and Constant Osteoarthritis Pain (ICOAP) questionnaires.
- Change in Six Minute Walk Test (6MWT) [ Time Frame: Week 1 and Week 13 ]Participants are asked to walk as far as possible for a total of six minutes at a self-selected pace in an obstruction-free rectangular hallway. Distance traveled is recorded in metres (m).
- Change in 30-second Chair Stand [ Time Frame: Week 1 and Week 13 ]Participants are asked to cross their arms over their chest and rise and sit back down in a chair as many times as possible in 30 seconds.
- Change in Timed Up and Go (TUG) [ Time Frame: Week 1 and Week 13 ]Participants are asked to raise from a standard chair, walk forward 3-metres until an orange cone is reached, walk around the cone, then walk back to the chair and sit down. The test is to be completed as quickly and safely as possible without running. The trial is repeated a second time and the quickest time (in seconds) is recorded.
- Change in Stair Ascent and Descent [ Time Frame: Week 1 and Week 13 ]Participants are asked to climb a standard flight of 9 stairs as quickly and safely as possible without compromising safety. Stair ascent and descent are assessed individually. Time to climb the stairs are recorded (in seconds) and averaged over two trials.
- Change in Subjective Scales [ Time Frame: Week 1 and Week 13 ]The Centre of Epidemiologic Studies Depression Scale (19-items), the Athens Insomnia Scale (8-items), and the Perceived Stress Scale (10-items) will be given to the participants to gather information on feelings of depression, sleeping patterns, and perceived stress, respectively.
- Change in Cardiovascular Fitness [ Time Frame: Week 1 and Week 13 ]Cardiovascular fitness is assessed using a sub maximal oxygen consumption cycle ergometer test. Heart rate is monitored using a Polar Heart Rate monitor and the test is terminated upon one of two conditions: a) volitional fatigue, or b) within 10 beats of 85% of the age-predicted maximum heart rate is achieved. Values are recorded in mL/kg/min.
- Change in Biomechanical Outcomes [ Time Frame: Week 1 and Week 13 ]Participants will be asked to partake in a complete kinematic, kinetic, and electromyographic analysis of gait and static postures using floor-embedded force plates, a 9-camera motion capture system, and a wireless electromyography system. Knee adduction moment (KAM; Nm/kg), normalized electromyography to a percentage of their maximal effort (%MVIC), and muscular co-activation (%) are the variables of interest.
