After preparing a list of all patients with inclusion criteria, a simple random sampling method of a random number table will be used. Thus members of the community are numbered from 1 to N, then a row and a column are randomly selected, the intersection of the row and the column is the starting point for sampling. From this point and at the choice of the researcher, one direction (top, bottom, right or left) will continue to select the samples until the desired number (60) is reached.Because the samples were obtained from a larger population and based on the allocation of numbers to individuals, they are placed in the table from the beginning, and even the researcher himself does not know from the beginning of the study who the assigned number belongs to, using a random table of numbers to get a sample of the homogeneous community (the community has similar conditions for entering the study) so that the chances of being selected as a sample are the same for all and the condition of random selection of the sample is observed, in the next step, after obtaining the required 60 samples, the odd and even methods will be used to assign the samples to the intervention and control groups. In this way, based on the contractual procedure, the obtained odd numbers (thirty persons obtained from the random table of numbers) are assigned to the intervention group and the obtained even numbers (thirty pairs obtained from the random table of numbers) are assigned to the control group. That is, the randomization process is first selected to select the required sample based on the random table of numbers, and in the next step, the sample obtained based on the odd and evenness of the specific number obtained from the random table of numbers is assigned to two groups of intervention and control. The purpose of this work is to observe randomness and equal chance in both stages
