Measure	Time frame
The Effect of Protective Knee Brace on Ankle and Knee Joint Co-contractions. Timepoint: The current research was carried out in two stages: pre-test and post-test. In this way, first, all the subjects were justified in terms of information about the research, the benefits of using the knee brace, the risks of cross knee development and secondary injuries. Then, before starting the test, the subjects warmed up their joints and muscles for 15 minutes. Subjects were placed behind the specified location, which was marked on the floor with colored tape. Subjects were asked to jump as high as they could and land with both feet on the marked spot. Then the jump and landing test was repeated three times by the subjects. A correct effort was considered when the subjects maintained their balance, and the software correctly recorded the electrical activity data of the muscles. If the subjects lost their balance or their electrical activity was not recorded, the attempt was repeated. In the post-test phase, the subjects were asked to tie the studied knee brace to the knee of their superior leg. Then, jumping and landing using a knee brace was repeated as in the pre-test phase in three attempts. At the end, the subjects were busy cooling down to prevent possible injuries after performing the efforts. The brace used in this study was the BeActive model 1031 knee brace. This brace is a flexible type without arm and strap for adjustment. The subjects of both the crossed knee group and the healthy group used this type of brace. Method of measurement: The variables were measured using an electromyography device.	—
