Abstract
Background: Obesity is recognized as a major public health problem and it is associated with various musculoskeletal disorders, including impairment of the spine and osteoarthritis. Objectives: to investigate the correlation between different degrees of obesity and non-specific low back pain as well as the mechanical factors that may affect this correlation. Methodology: Ninety obese females suffering from non-specific low back pain participated in this study; their ages ranged from 20 to 45 years. Subjects were subdivided into three groups according to their Body mass index (BMI), thirty patients in each group. group A, B and C represent grade I, II and III obesity respectively. Outcome measures were Visual analogue scale (VAS),Oswestry Disability index(ODI), lumbar lordotic angle (LLA) and Lumbar mobility, Results: There was moderate positive significant correlation between BMI, VAS, ODI and lumbar mobility during extension, while there was moderate negative significant correlation between BMI and LLA as well as lumbar mobility during flexion. Conclusions: Different degrees of obesity correlate with non-specific low back pain as well as the mechanical factors that may affect this correlation
