Based on the table of random numbers, the patients included in the study will receive random numbers. By receiving codes 1, 2, 3, etc., they are placed in each of the three treatment groups. By receiving the number 1 (4, 7, 10, etc.), it enters group one. At first, he enters the pre-test stage and then begins the respiratory muscles training . By receiving code 2 (5, 8, 11, etc.), it is placed in the second group. They enter the pre-test stage. Then they participate in the peripheral muscles training . By receiving code 3 (6, 9, 12, etc.), it is placed in the third group (control). They enter the pre-test stage. They then continue to study. The treatment starts with the main therapist, but the results and interpretation are the responsibility of the people who are blind to the groups.
