ABSTRACT
STUDY DESIGN: The lumbar segmental motions were analysed in asymptomatic volunteers. OBJECTIVES: To obtain normative data on flexibility and Graf's instability degree in sagittal plan of the normal lumbar spine. SUMMARY OF LITERATURE REVIEW: Although several clinical and radiological measurement tech niques are available, little is known about the normal range of lumbar spine motion. As a consequence, the diagnostic evaluation of radiographs are frequently based on subject opinions rather than object reality. MATERIALS AND METHODS: The authors have checked lumbar flexion-extension Yiews of 95asymptomatic volunteers who were divided into 5 groups by the age, and then their flexibility and Graf's instability degree were calculated by Graf's method with using Graf/Bar Mark II(digitalizing table) and personal computer program(RachisR). Evaluation of the sexual difference and comparison of the difference of each age group in spine level were done RESULTS: 1. There were significant differences in flexibility among age groups(p0.05). 3. Graf's instability degree was not different among 5 age groups(p>0.05), and between male and female(p>0.05). 4. The mean Craf's instability degree was below 8o in L2-3, L3-4, and L4-5 segment, but above 8 in L5-S1 segment(male: 11.62+/-9.27 , female. 11.11+/-8.70). CONCLUSIONS: Although we observed small subjects, these results are the basic steps toward more objective and careful interpretation of flexibilty and Graf's instability degree.
