During the first 5 minutes, researchers will explain with pictures how the exercise is done and show it to the patient. The patient will then be asked to perform the exercise for 10 minutes under the supervision of the researchers. If the patient has performed the DBE correctly, the procedure will be discontinued. Otherwise, the patient will be asked to practice for another 5 minutes. If at the end of this period the patient still cannot perform the exercise correctly, he will be removed from the sample. DBE will be performed according to Cleveland Clinic guidelines.
