Low back pain is a leading cause of disability with functional and occupational impact. This quantitative cross-sectional study evaluated the prevalence of low back pain and its relationship with lumbar mobility in the staff of Universidad Internacional SEK (UISEK), Miguel de Cervantes campus, Quito. Of the 137 employees, 71 completed the Nordic Musculoskeletal Questionnaire, and 60 underwent biomechanical lumbar flexion mobility measurements. 73% reported having experienced low back pain in the past 12 months. Regarding mobility, 53.3% had poor mobility (<40°), 43.3% normal (40–70°), and 3.3% excellent (>70°). A chi-square goodness-of-fit test was applied to compare observed versus expected values in a healthy population, and a Wilcoxon test was used to compare mobility angles between those with and without pain. A significant deviation was found (p < 0.001) in the distribution of mobility, and lower mobility in those with pain (p = 0.0009, r = 0.40). These findings support an association between low back pain and restricted mobility, possibly influenced by sedentary behavior and occupational factors.The main limitations of this study include the reduced sample size and the single-center design, which may limit the generalizability of the findings
