摘要: STUDY DESIGN A descriptive design of posteroanterior stiffness in the lumbosacral spine. OBJECTIVES To measure between L1 and S1 to establish pattern individuals with no history low back pain. SUMMARY OF BACKGROUND DATA In clinical examination for pain, manual assessment abnormal is used determine site pain-producing lesion. However, there little objective evidence variation levels normal spines or factors that stiffness. METHOD Posteroanterior was measured a specially developed measuring device at each six vertebral S1. Force-displacement relations were computed level. The gradient linear part force-displacement relation as coefficient stiffness, amount displacement 5 N 30 applied force (D5-30) length toe region. RESULTS Overall significant trend increasing from Ninety percent difference scores adjacent level comparisons less than 3.6 N/mm. There considerable patterns found different individuals. D5-30 correlated significantly skinfold thickness measurements body mass index. CONCLUSION S1, but this influenced by variables related type (adiposity).
