Condition
Knee joint osteoarthritis
Intervention
The 12 week aquatic exercise was specifically directed to improve quadriceps and hamstring muscle strength, power and muscle mass, and thus mobility. The control group did not receive any intervention. Participants were encouraged to continue their lives as usual and maintain their level of physical activity during the trial. Sessions were conducted twice a week in small classes including 4 - 5 people. Measurements were performed before and after the 12 week training period for both study groups.

Primary outcome measure
Physical functional and mobility difficulties were assessed by Western Ontario and McMaster Universities osteoarthritis index (WOMAC) questionnaire, and mobility limitation by 10-metre habitual walking speed and stair ascending time. Measured 2 - 3 days before and after the 12 weeks training period both in exercise and control groups.
Secondary outcome measures
Knee extensor (KEP) and flexor power (KFP) were assessed isokinetically, and thigh muscle cross-sectional area (LCSA) by computed tomography (CT). Measured 2 - 3 days before and after the 12 weeks training period both in exercise and control groups.
