      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Simple non-probability randomization is done using the numbered and sealed envelope method. With the help of physiotherapist 1 (evaluator), patients are randomly divided into 2 intervention and control groups through the sealed envelope method. be. For this purpose, 38 envelopes are prepared, which are filled with the numbers 1 and 2 (19 envelopes containing the number 1 and 19 envelopes containing the number 2). The numbers 1 and 2 each separately means entering one of the intervention and control groups, which only physiotherapist 2 (therapist) knows about. Before the patient chooses the envelope, we will change the order of the envelopes several times, and after the patient chooses the envelope, its number is noted on the evaluation sheet, Blinding description: The participants and the evaluating physiotherapist are blinded to the study groups. Both groups of patients receive whole body vibration treatment, and in one group, the cuff around the thigh is filled with air, and in the other group, it is simply closed without filling with air, and the patients do not see any difference between the two groups. The evaluating physiotherapist does not know which treatment group each patient is in, and the assignment of patients to two groups is done by the treating physiotherapist.</study_design>
