Design outcomes

Primary

Measure	Time frame
Landing jump pattern. Timepoint: Pre-test at the beginning of the study and post-test after 6 weeks. Method of measurement: Subjects will be assessed using the Vine test to identify individuals with valgus dynamic knee defects. To perform the vine, the athlete stood with his legs shoulder-width apart and jumped vertically, raising his knees as high as possible. At the highest point of the jump, the thighs will be parallel to the ground. When landing, the athlete must start the next vine jump. This test will run for 10 seconds.;Static balance. Timepoint: Pre-test at the beginning of the study and post-test after 6 weeks. Method of measurement: In the stork test, the subject will stand on his / her superior foot, and in this position, he / she will place the sole of the non-superior foot in the inner part of the knee of the superior foot and place his / her hands on the crown of the sides. In this position, the subject is asked to stand on his toes and the time he can maintain this position is recorded with a stopwatch. The method of performing the Y test for dynamic balance was that the person stood on his superior foot and performed the achievement operation three times in the anterior path, this method is repeated in the internal posterior and posterior external paths.;Dynamic balance. Timepoint: Pre-test at the beginning of the study and post-test after 6 weeks. Method of measurement: The modified Y-balance test will be used to assess the dynamic balance. The subjects stand on one leg at the center of the intersection of the lines. Have achievements. The method of performing the test is that the person stands on his superior foot and the achievement operation is repeated three times in the anterior, posterior and external posterior paths.;Motor function screening test score. Timepoint: Pre-test at the beginning of the study and post-test after 6 weeks. Method of measurement: How to score in this test is as follows: correct movement without compensatory movements	—
