NOTE: There are several methods for measuring the range of motion of the
lumbar and thoracic spines. Each method has its own advantages and disadvantages
(no method is completely valid or reliable, and normal values are not well
established for any method). The method illustrated here is a good compromise.
Test Position
Subject sitting
Stabilize pelvis
Do not allow sidebending, forward bending or backward bending
Rotate thoracic and lumbar spines
Normal Range (unilateral)
45o (American Medical Association)
Goniometer Alignment
Axis - center of superior aspect of head
Stationary arm - aligned with anterior superior iliac spines
