Introduction: Increasing the angle of curvature of the spine in the lumbar region is precursor from many musculoskeletal disorders. Therefore, the measurement of easy, fast and accurate angle of lumbar lordosis will an important role in the prevention of these discomforts. The purposes of this study are clinical examination, clinical examination, and Facilitate measurement of lumbar lordosis curvature and prevent unnecessary radiation exposure to individual body and design and manufacture of lumbar lordosis system. System designed in this study do not the risks and other methodological problems and is acceptable in compared with standard indicators of Delmax.

.

Methods and Materials: In this study, surveyed lumbar lordosis 50 participants of male and female using system of the measurement lumbar lorsosis and findings were compared with results of delmax index.

.

Results: The lumbar lordosis of natural based on Delmax index between 96% -94% and based on designed system is equivalent to 40 to 60 degrees. Participants had 78% of normal lumbar lordosis, 12% Kyphosis and 10% Lordosis. The sensitivity of system in identifying healthy individuals and patients 100% and 55.6% respectively and overall accuracy was 84% system.

.

Conclusion: The designed system had acceptable of accuracy in comparison with standard Delmax index.
