In the present study, random block sampling will be done in two intervention and control groups. The sequence of random allocation and the list of blocks will be obtained by the statistical consultant and with the help of R software. At first, after obtaining the necessary permits and referring to the research environment, the participants will be available and according to the entry criteria and then After obtaining informed consent, they enter the research. Then, according to blocks of four, each patient was randomly assigned to group A (intervention) or group B (control group). For example, after randomly selecting a block such as the BABA block, patients will be randomly assigned to the control, intervention, control and intervention groups, and the next patients in the AABB group will be allocated to the intervention, intervention, control and control groups. The number of people assigned to the groups will be equal. In this research, in addition to random allocation, sequence concealment will also be done. For this purpose, first a random sequence was created, then based on the size of the research sample, a number of envelopes are prepared and each of the created random sequences is recorded on a card and the cards are placed inside the envelopes in order. In order to maintain the random sequence, the numbering will be done in the same order on the outer surface of the envelopes. Finally, the lids of the envelopes are glued and they will be placed in a box respectively. At the time of registration of participants, based on the order of entry of eligible participants into the study, one of the envelopes will be opened and the assigned group of that participant will be revealed. People will be assigned to the desired group in the order of their entry into the study and randomly through randomized blocks.
