Measure
Yoga Intervention
Participants completed a yoga strengthening program designed for knee osteoarthritis (OA). This program was taught by a certified yoga instructor who was trained to deliver the strengthening program. Participants were asked to attend 3 classes per week for 12 weeks. Each class was 1 hour in duration.

PRIMARY outcome

Timeframe: 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.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 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).

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 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.

SECONDARY outcome

Timeframe: 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.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 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.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 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.

Outcome measures

SECONDARY outcome

Timeframe: 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.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 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.
