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 ANDMETHODS:
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 doneRESULTS:
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.
