The effects of flexion distraction on the segmental mobility and pain in chronic lumbar facet syndrome

M.Tech.Purpose: To determine what effects flexion distraction will have on males with chronic lumbar facet syndrome, in reference to intersegmental range of motion and pain. Method: Thirty male participants with chronic lumbar facet syndrome received flexion distraction technique. The trail consisted of seven visits over two to three weeks. Treatment was performed on the first to sixth visit, readings and questionnaires were completed on the first, fourth and seventh visits. Data collection was concluded before treatment on the mentioned visits. Subjective data consisted of the Oswestry Disability Index (ODI) and the Short-Form McGill Pain Questionnaire-2 (SF-MPQ-2). Objective data included global lumbar range of motion measurements using the Baseline Digital Inclinometer, and segmental lumbar range of motion by means of the Radiographical Midplane Angle method. Results: Objectively, clinical significance of the intersegmental lumbar range of motion increased from the L1/L2 to the L4/L5 level (2.2% - 17.7%), but showed no statistical significance. In relation to the maximal motion possible at these levels, the increase in motion escalated from 0.8% at the L1/L2 segment to 9.2% at the L4/L5 segment. The global lumbar range of motion showed clinical significant increase in all of the ranges except for extension, however statistical significance was found in right lateral flexion only (p = 0.045). The greatest increase in motion was observed in left lateral flexion (15.72%) and a decrease in extension (3.72%) was illustrated. Subjectively, the group showed statistical significant improvement in both the SF-MPQ-2 (p = 0.000) and ODI (p = 0.000). Clinical meaningful change was noted throughout the subjective data, which resultantly showed a 66% and a 67% change in pain respectively. Conclusion: Flexion distraction has shown to have clinical significant effects on segmental and thus global range of motion, and great clinical meaningful change in pain levels and pain perception. Thus specific segmental mobilisation does affect the segmental motion
