Randomization (investigator's opinion)
Randomized
Randomization description
Randomization is done based on the Random Number Generator software and based on the allocation concealment using the SNOSE method, They will be assigned to two groups. We ask the software to randomly assign numbers 1 to 50 to two groups A and B. Group A is the combined group of gluteus medius and short foot strengthening exercises and group B is the short foot exercises group. We put numbers in sealed envelopes, the range of numbers is 1 to 50. The number of subjects is 50 and they will be divided into two groups of 25. Then we ask the participants to take the envelopes containing the numbers and the number that each participant chooses is divided according to the division that we have already done ourselves, which number is in which group, the person will enter the desired group and we perform this kind of randomization of the participants.
Blinding (investigator's opinion)
