Design outcomes

Primary

Measure	Time frame
Proprioception. Timepoint: Before and after treatment. Method of measurement: Using a digital camera, the patient must estimate the angles defined for the injured knee.;Balance. Timepoint: Before and after treatment. Method of measurement: Using the plate machine, the static balance is measured in four positions: standing on two legs with open eyes, standing on two legs with closed eyes, standing on one with open eyes, standing on one with closed eyes, and dynamic balance of activities. Used to transfer weight along the anterior-posterior, internal, or external surfaces of a computer screen.;Strength of the quadriceps. Timepoint: Before and after treatment. Method of measurement: Quadriceps muscle strength using a dynamometer.;Knee function. Timepoint: Before and after treatment. Method of measurement: KOOS questionnaire.	—
