The spine, columna vertebralis, is the central bony pillar that represents the main system that supports the whole body and plays an important role in almost all movements of our body. Lumbar pain syndrome is of multifactorial etiology. It is divided into specific and non-specific. Patients with non-specific LBS (90%) are those who feel pain, but whose life and work ability are not compromised, and by improving your quality of life, exercising and occasionally going to physical therapy, they can return to their work and life opportunities. The cause of pain can come from several or different places such as adjacent muscles, ligaments, tendons, fascia and from the spine itself. Diagnostic examination is rarely required during treatment of non-specific lumbar pain syndrome. Physiotherapy assessment, short or extensive, is an important part of pain management. It is done before the beginning of rehabilitation and after the end of therapy and includes: assessment of spinal mobility (eg index of sagittal mobility of the spine, Schober test, etc.), assessment of pain intensity (VAS scale, numerical pain scale, etc.), assessment of muscle strength and strength and the use of various questionnaires that include examining the functional abilities of the respondents in carrying out daily activities. The assessment begins with observation as soon as the patient arrives at the office. Physiotherapy interventions are methods that can increase functionality and reduce pain. Medications should not be the primary treatment for non-specific lumbar pain syndrome. The education of patients is of special importance and it is performed by a doctor in cooperation with a physiotherapist.
