Comparison of Lumbo-Pelvic Stability between Patients with Chronic LowBack Pain and Healthy Subjects

Because of the importance of lumbo-pelvic stability as one of the suggested factors to prevent low back pain and since to date no study accomplished to compare lumbo-pelvic stability between chronic low back pain (CLBP) and healthy subjects, the aim of this study was to determine and to compare lumbo-pelvic stability, lumbar lordosis, and lumbar mobility between CLBP and healthy subjects. Thirty CLBP patients and thirty healthy subjects through simple non-probability sampling participated in this cross-sectional analytical study. Lumbar lordosis, lumbar flexion and extension range of motion, lumbo-pelvic stability was measured through flexible ruler, modifiedmodified schober test, and Pressure Biofeedback Unit (PBU) respectively. ANCOVA test were used for statistical analysis (p 0.05). Also lumbar lordosis, and lumbar flexion and extension range of motion did not significantly differ between two groups (p>0.05). There is no difference between CLBP and healthy subjects in terms of the lumbo-pelvic stability, lumbar lordosis, lumbar flexion and extension range of motion. The present study supported that lumbar lordosis, lumbar mobility, and lumbo-pelvic stability not affected by CLBP.
