Pressure pain threshold assessed by pressure algometry

Assessed by questionnaire (FACT-BP) on a scale from 0 to 4. Higher scores mean a worse outcome.

Assessed by questionnaire (Brief Pain Inventory) on a scale from 0 to 10. 0 meaning no pain, 10 meaning worst pain ever.

Assessed by questionnaire (painDETECT) on a scale from 0 to 10. 0 meaning no pain, 10 meaning worst pain ever.

Assessed by questionnaire (SF36v2) on a scale from 1 to 5. Higher scores meaning a worse outcome.

Assessed by tonometry using SphygmoCor system

Assessed by tonometry using Arteriograph24

Handgrip strength, elbow and knee flexion and extension assessed by dynamometer chair (Good Strength; Metitur Ltd, Finland).

Measures the time to stand up, walk three metres in a straight line, and immediately return to the chair.

Measures the time for ten consecutive chair rises.

Inflammatory Back Pain and Gluten Free Diet

Musculoskeletal (back pain) evaluation, from baseline at 12 months of GFD, according to the scores calculated on the basis of Visual Analogue Scales for Musculoskeletal (back pain), taking into account whether the patients adhered or not to the GFD.

Changes in cytokines production from peripheral blood mononuclear (PBMC), from baseline (i.e. at diagnosis) at 12 months of GFD, taking into account whether the patients adhered or not to the GFD.
