Abstract

Background:An estimated one-tenth of the population suffered  from Rheumatoid Arthritis (RA), the most prevalent chronic inflammatory arthritis. The purpose of this study is to identify the risk factors for dysfunctional low back pain in RA patients, as well as to examine the relationship between these variables and the severity, activity, and clinical symptoms of the illness. Methods: This study included 40  RA patients and 40 age and sex matched healthy individuals with low back discomfort. All patients were subjected to back examination, assessment of RA disease activity using the disease activity score (DAS28), clinical assessment of RA disease severity using RA severity score (RASS) and the modified Larsen score (MLS). Structural radiographic changes were evaluated by plain radiograph and magnetic resonance image (MRI) on lumbar spine. Results: RA patients had higher DAS, visual analogue score (VAS), RASS, increased Platelet count, low Hemoglobin percentage and total leukocyte count, vertebral endplate and/or facet erosion, disc bulge and disc prolapse in MRI of the back which are  linked to dysfunctional lower back pain. Conclusion: Radiological lumbar abnormalities, particularly lumbar spondylolisthesis, are common among RA patients. Furthermore, despite the fact that LBP in RA patients was effectively managed, the activity of daily living may be more influenced by LBP, which was higher among patients with active disease status. These findings show that RA patients' lumbar therapy should focus on disease management as well.
