A study entitled, "evaluation of ankylosing spondylitis spinal mobility measurements in the assessment of spinal involvement in psoriatic arthritis" found that similar methods used in AS patients for measuring spinal involvement also worked in psoriatic arthritis.

The authors of the study write, "Modified Schober test, lumbar side flexion, and cervical rotation were the more suitable measurements for assessing axial PsA."

They conclude that, "The spinal measurements used to evaluate AS performed well to assess spinal involvement in PsA. These measurements, notably the modified Schober test, lumbar side flexion, and cervical rotation, should be used in daily clinical practice to assess PsA patients with spinal involvement."
