Abstract EN

This study aimed to verify the Validity and Reliability for (Al-Qudah,2011) test (which relied on expert arbitration) and to identify the effect of the formed angle degrees (45),(90) and (120) between the thighs and legs on the level of axial rotation in the lumbar spine; as in the description of that test.

This study was conducted on (12) healthy males volunteers using a radiographic apparatus (XRay) at the Posterior view using three different Somatic positions during rotating trunk axially to the right and left.

The Researcher used a form to describe the axial lumbar rotation level for each vertebrae {no rotation (Absent), the existence of a simple rotation (Minimal), and existence of a large rotation (Significant)}, to describes the Axial Rotation from the Tenth Thoracic (T10), to the first Sacral (S1).

All grades were collected for each single (X ray) picture, the grades averages were taken and analyzed statistically using tests: means, standard deviations, one way ANOVA, Scheffe.

Results showed that when the formed angle degree between the thighs and legs was (45), an axial rotation was found in the thoracic spine vertebras (rotation was Significant): (T10), (T11), (T12), while the lumbar spine region was stable (rotation was absent): (L1), (L2), (L3), (L4), (L5) and (S1).

Also, at the same formed angle degree, there was significant difference between vertebras: (T12) and (L1) at the aspect of axial rotation.

Conclusion: the current form of (Al-Qudah, 2011) test for measuring the Lumbar Axial range of motion is not showing the properties of a Valid test specification.

So, the condition was modified.

The Axial Lumbar range of motion between (T12) and (L1) vertebras {when the formed angle degree between the thighs and legs is (45)} can be measured only by using the modified test of (AlQudah, 2011).

Recommendation: It was suggested to publish the modified test of (Al-Qudah, 2011) for measuring the Lumbar Axial range of motion between (T12) and (L1) vertebras; when the formed angle degree between the thighs and legs is (45).

Also Research in this field is deemed necessary using the same modified test during multi acute angles formation; to identify there effect on the segmental axial rotation in the lumbar spine; in both males and females subjects.
