Patients based on random numbers generated by the program (Excel version 2016 and RANDBETWEEN function) that values less than 5.0 (0.0009-0.000) will be assigned to the intervention group and more than 5.0 (0.500-999) will be assigned  to the control group, Blinding description: The project partner, who does not know how the volunteers are assigned in the groups, will evaluate the incidence and severity of low back pain in the project.</study_design>

      <i_freetext>Intervention 1: In the intervention group, patients will be asked to place an air mattress under the lumbar vertebrae according to the anatomical position before surgery and after performing spinal anesthesia in the supine position until the anesthetic effect wears off.
