Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: Knee estensor and flexor muscle strength and power enhancement, measured through isokinetic knee extension and flexion strength test using an isokinetic dynamometer at angular velocities of 60°/s and 180°/s, from at least 15% variation between pre and post intervention measures. ;Observed outcome 1: After the exercise program there was an increase of 24,1% in total work of knee flexor muscles; 16,8% in knee flexor muscles peak torque; 15,6% increase in knee extensor muscle power; and 26,8% increase in knee flexor muscle power.;Expected outcome 2: Enhancement in physical function, represented by increased usual gait speed measured in a linear 4-meter course; decreased time to perform five times Sit-to-Stand Test; increased distance in the 6minute Walking Test, performed in a linear 30 meter course; decreased time to perform the Timed Up and Go Test; increased gait speed measured through 10-meter Walking Test in maximum velocity, from at least 5% variation between pre and post intervention measures. ;Observed oucome 2: After the intervention was observed 10,1% reduction on time to perform the sit-to-stand test; 9,2% reduction on time to perform the TUG test; and 13,2% on covered distance in 6 minute walking test. There were no changes in gait speed on 4m and 10m walking tests.;Expected outcome 3: Reduction in KOA symptoms of pain, joint stiffness and functional limitations, measured through Western Ontario and McMaster Universities Index (WOMAC), from at least 10% variation between pre and post intervention measures. ;Observed outcome 3: Reduction of 22% in joint stiffness; 12% enhancement in physical function; and 15% on WOMAC total score. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome 1: Perceived pain measured through a visual analog scale, from at least 50% variation between pre and post intervention measures.;Observed outcome 1: Perceived knee pain reduction of 75%.;Expected outcome 2: Decreased postural sway measured through static balance test in a force plate, from 10% variation in pre and post intervention measures.;Observed outcome 2: there were no changes in postural sway after the intervention.;Expected outcome 3: Enhancement on usual gait spatial and temporal paramenter, measured through kinetic and kinematic gait evaluation, using a camera system, a force plate and an image processing software, from 5% variation in observed parameters between pre and post intervention measures. ;Observed outcome 3: There were no changes in usual gait spatial and temporal parameters after the intervention. | — |
