Comparative Study of Sacroiliac Joint Dysfunction and Lumbar Flexibility between Normal Subjects and Sacroiliac Joint Dysfunction Patients

Abstract
Background: Low Back Pain (LBP) is a symptom rather than a disease diagnosis. Pathology in the low back might affect the pattern of movement rather than only the range of movement ROM. Approximately 10% with LBP do not respond to treatment and develop chronic LBP. The cause for this non-response to treatment is lack of specific diagnosis and inability to distinguish, in some people, pain arising from the Sacroiliac Joints (SIJs) or the lumbar spine.
Aim of Study: This study was conducted to identify the relationship between Sacroiliac joint dysfunction SIJD and lumbar spine movement in sagittal and frontal plan.
Subjects and Methods: Forty participants aging 20:40 years divided into 2 groups. Group (A) consisted of 20 healthy participants, Group (B) SIJD consisted of 20 subjects were positive of at least 3 SIJ provocative test. All the participants on the study, pelvic asymmetry was measured by PALM device also spinal flexibilityof lumbar spine was assessed in sagittal and frontal plan.
Results: There was negative weak significant correlation between mean difference of pelvic inclination and Extension-Flexion E-F of lumbar (r=–0.405, p=0.014*). While, no significant correlation between mean difference of pelvic inclination and lumbar flexion, left side bending, right side bending, and over all side bending L-R of lumbar.
Conclusion: There was change of lumbar spine mobility in sagittal plan on extension and overall sagittal ROM with SIJD patients, though in comparison between groups it showed that patient with SIJD had less overall frontal plan ROM.
