Chronic pain is pain whose duration usually exceeds a period of three months and standard treatment is ineffective. This pain brings many changes in physical and psychological functioning to the individual and can even lead to a reduction in the quality of life. The main goal of the project is to determine the impact of pain and treatment on the quality of life and patterns of physical activity in patients with chronic pain. Furthermore, evaluate specific changes in quality of life, disability, physical activity, BMI, and body composition after the application of therapeutic and educational measures. Another goal is to validate an assessment tool for assessing the activity patterns of patients with chronic pain. In the first phase, the Czech version of the Patterns of Activity Measures-Pain scale (POAM-P/CZ) will be validated to assess the activity patterns of individuals with chronic pain. Subsequently, a prospective observational study will be carried out with the aim of comparing differences in quality of life, disability, activity patterns, BMI (body composition), and psychosocial variables after the application of targeted treatment measures and educational interventions. The subjective assessment of pain will be supplemented by the assessment of the Analgesia Nociception Index. The results of the project can contribute to the development of effective long-term strategies for the optimization of educational programs to support the self-management of chronic pain and the specific focus of health care.
