Background: Back pain has become an important health issue now days. Patients with chronic non-specific low back pain (CNSLBP) have pain, disability, and decreased functional capacity, however, the association is still unknown. Objective: Assessment of disability by using Oswestry Disability Index in chronic non- specific low back pain patients. Methodology: This is a descriptive type of cross-sectional study was conducted in the department of PM & R, DMCH from both outpatient and inpatient. Total 103 patients having with low back pain, seeking treatment in department of Physical Medicine & Rehabilitation during the study period, fulfilling enrollment criteria was enrolled in this study. All the cases were evaluated properly with complaint of chronic non-specific low back pain. The quantitative observations were indicated by frequencies. Chi square test was used to analyze the categorical variables, shown with cross tabulation. ANOVA test was used for continuous variables. A “p” value <0.05 was considered as significant. Results: Of the patients, over half (52.4%) had severe disability, followed by moderate (27.2%), crippled (13.6%), and little (7-8%). A statistically significant increase in pain intensity (p <0.001) corresponds to an increase in the degree of disability. Conclusion: The severity of impairment worsens as pain intensity and duration increase. The length and degree of pain are significantly associated with disability.
