      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: After the initial evaluations, patients will be allocated to either the intervention or control group using block randomization. Randomization will be conducted via Randomization.com. Considering the two groups (intervention A and control B), six blocks of four participants each will be generated. Each allocation sequence will be documented on a card and placed in a sealed envelope. As participants are enrolled, the envelopes will be opened sequentially to reveal the group assignment. This study is double-blind: both the participants and the outcome assessor will remain unaware of group allocation. Randomization and outcome assessment will be performed by an individual who is not involved in the treatment of the patients, ensuring that the assessor is blinded to the intervention type, Blinding description: In this double-blind study, patients and the evaluator are unaware of the type of group assigned. Randomization and intervention will be performed by a person who is not involved in the patient assessment process, and the evaluator is also unaware of the type of intervention. Patients in both groups receive the same treatment. The intervention group receives real treatment and the control group receives sham. The intervention is performed for all patients in the same location and in the morning shift.</study_design>

      <i_freetext>Intervention 1: Intervention group: Routine physiotherapy and exercise therapy and impulse therapy will be used. Impedance mode impulse therapy, 900 kHz frequency will be used on the affected points with the aim of vascularization, three times a week for ten sessions. The training includes: a disorder-based exercise and stretching program and disorder-based manual therapy. Intervention 2: Control group: Routine physiotherapy and exercise therapy will be used three times a week for ten sessions. Exercise includes: a disorder-based exercise and stretching program and disorder-based manual therapy.</i_freetext>
