Abstract |
Objective To measure the lumbar segmental range of motion (ROM) with 3-dimensional motion analysis system and compare the results with radiologic ROM measurements. Method Ten healthy adult volunteers were included. We attached surface markers at the corresponding skin surface of each lumbar vertebral bodies and measured lumbar segmental ROM in flexion-extension, right bending, left bending, axial rotation with 3-D motion analysis. We compared some of the results with radiologic segmental ROM measurements.
Results In 3-D motion analysis, segmental ROM of flexion and extension, right bending, left bending, right rotation, left rotation were, respectively: 10.1o, 45o, 3.5o, 1.7o and 1.9o (L1-L2); 17.9o, 6.2o, 5.1o, 1.4o and 1.1o (L2-L3); 15.0o, 7.2o, 4.9o, 2.1o and 1.1o (L3-L4); 14.9o, 5.8o, 4.6o, 1.7° and 1.6° (L4-L5); 10.6o, 4.9o, 3.8°, 2.6° and 0.8° (L5-S1). There was no statistically significant difference in segmental ROM between 3-D motion analysis measurements and radiologic measurements except L5-S1 right bending, L2-L3 and L5-S1 left bending. No statistical significant difference in lumbar flexion and bending ROM was found between two methods.
Conclusion 3-D motion analysis is a useful method when measuring the lumbar segmental range of motion and it has an advantage to analyze segmental lumbar motion with three directions simultaneously. (J Korean Acad Rehab Med 2003; 27: 424-432)
