Rheumatoid Arthritis (RA) is a chronic autoimmune disease that often results in debilitating pain for those afflicted. Accurate pain assessment is crucial for effective management and treatment of RA patients. This review aims to provide a concise overview of the various pain assessment scales and tools utilized in the evaluation of pain among RA patients. These scales encompass both self-report and clinical assessment tools, each with its unique strengths and limitations. The assessment scales discussed in this review include the Visual Analog Scale (VAS), the Numerical Rating Scale (NRS), the Disease Activity Score (DAS), the Health Assessment Questionnaire (HAQ), and the Rheumatoid Arthritis Pain Assessment Scale (RAPAS). Special attention is given to the RAPAS, a relatively newer instrument designed to comprehensively evaluate pain in RA patients by incorporating both selfreport and physician assessment components. Understanding the nuances of these pain assessment tools is essential for healthcare providers in optimizing pain management strategies and improving the quality of life for individuals living with RA. This review provides a valuable resource for clinicians and researchers seeking to enhance their understanding of RA pain assessment methodologies.


Rheumatoid arthritis • Visual analog scale (VAS) • Numerical rating scale (NRS) • Rheumatoid arthritis pain assessment


Rheumatoid Arthritis (RA) is a chronic autoimmune disease characterized by inflammation of the synovial joints, leading to joint pain, swelling, stiffness, and progressive joint damage. One of the primary challenges in managing RA is the assessment and management of pain, which significantly impacts the quality of life of affected individuals. Accurate pain assessment is crucial for tailoring treatment strategies, monitoring disease progression, and evaluating the effectiveness of interventions. This review provides a comprehensive overview of various pain assessment scales and tools used in the context of Rheumatoid Arthritis. The effective evaluation of pain in RA patients requires a multidimensional approach, considering both patient-reported outcomes and clinical assessments. This review highlights the key pain assessment scales commonly employed in clinical practice and research [1].

We will delve into the Visual Analog Scale (VAS) and Numerical Rating Scale (NRS), which are frequently used self-report tools for quantifying pain intensity. Additionally, we will explore the Disease Activity Score (DAS) and the Health Assessment Questionnaire (HAQ) as tools that encompass pain assessment as part of a broader disease evaluation [2]. Furthermore, we will place particular emphasis on the Rheumatoid Arthritis Pain Assessment Scale (RAPAS), a relatively newer instrument designed to comprehensively assess pain in RA patients by integrating patient self-reports and physician assessments. RAPAS offers a holistic view of pain, considering its impact on various aspects of daily life. This review aims to provide healthcare professionals, researchers, and clinicians with a concise yet informative resource for understanding and selecting appropriate pain assessment tools in the management of Rheumatoid Arthritis. By enhancing our understanding of these tools, we can better tailor treatment plans and improve the overall well-being of RA patients [3].

Numerical rating scale

The Numerical Rating Scale (NRS) is a pain assessment tool commonly used in healthcare settings to measure pain intensity. It typically involves a scale where the individual is asked to rate their pain on a numerical scale, with 0 indicating no pain and a higher number representing increasing pain severity. However, you mentioned "without point," which suggests a modification or variation of the NRS. If you meant to refer to a simplified version of the NRS that doesn't involve specific numerical points, you might be describing a simple verbal pain rating scale. In this case, individuals are asked to describe their pain using words such as "no pain," "mild pain," "moderate pain," or "severe pain" without assigning numerical values. This verbal description approach can be more accessible for certain individuals, especially those who might find it challenging to assign a precise numerical rating. It provides a qualitative assessment of pain intensity based on descriptive terms rather than numerical values. In summary, a Numerical Rating Scale without specific numerical points would likely involve using verbal descriptors to assess pain intensity, providing a more qualitative assessment of pain severity [4].

Visual analog scale

The Visual Analog Scale (VAS) is a widely used pain assessment tool in healthcare and clinical research. It is a simple and effective method for individuals to self-report their pain intensity. The VAS typically consists of a 10 cm (or longer) horizontal or vertical line on a piece of paper or a visual display. The two endpoints of the line are labeled, with one end representing "no pain" and the other end representing "worst pain imaginable." The individual is asked to mark or point to a spot on the line that best represents their current pain level. They can make a vertical mark on the line to indicate their pain intensity. The distance (in millimeters or centimeters) from the "no pain" end of the line to the individual's mark is then measured. This measurement is taken as the pain score. The score typically ranges from 0 (indicating no pain) to 100 (indicating the worst pain imaginable). The VAS provides a continuous scale for assessing pain intensity, allowing for a more precise measurement compared [5].

Materials and Methods

Describe the characteristics of the study participants, including demographics, sample size, and inclusion/ exclusion criteria if applicable. Explain the overall design of the study, such as whether it's observational, experimental, cross-sectional, longitudinal, etc. Detail the data collection methods, instruments, or tools used in the study, including any surveys, questionnaires, or measurements. Specify how and where the data were collected (e.g., clinical settings, laboratory, online surveys). If applicable, describe any ethical considerations and approvals related to participant recruitment and data collection. Define the variables examined in the study, including independent, dependent, and control variables. Outline the step-by-step procedures followed during the study.
