Psychometric Properties of Pain Scale in Low Back Pain

Demographic and clinical information of the participants will be recorded using a standardized form. The cognitive status of the patient will be evaluated according to the answers to the questions asked to the patient during the questioning of demographic data and reading and signing the consent form. The participants will be asked to complete a series of questionnaires to assess pain intensity and characteristics, pain-related functional disability, and pain-related fear-avoidance behavior. To record the presence and severity of pain behaviors exhibited during physical performance tests, patients will be asked to complete 5 functional tests (repetitive trunk flexion, repetitive sit-to-stand, timed get-up-and-go test, reach with load, 50-step walk test) and observers will simultaneously complete the Pain Behavior Scale. Each participant will be asked to attend two testing sessions separated by one week and occurring before the start of treatment.
