Scientific titleEffects of progressive aquatic resistance training on mobility limitation and lower leg impairments after unilateral knee replacement
Study objectivesProgressive aquatic resistance training improves mobility ability, muscle power and mass after knee replacement.
Ethics approval(s)The Ethical Committee of the Kymenlaakso Central Hospital gave approval on the 16th February 2004
Health condition(s) or problem(s) studiedKnee joint osteoarthritis
InterventionThe 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.
Intervention typeOther
Primary outcome measurePhysical 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 measuresKnee 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.
