Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This protocol will report on the validation of IASP clinical criteria for indentifying nociplastic pain. The study will include 2 phases. In the first phase, the vignette method will be used while the second phase will include the use of the algorithm in the evaluation of patients with chronic pain.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

For the purposes of the study, in the first phase, clinical vignettes will be created, ie short hypothetical scenarios of patients with chronic musculoskeletal pain. The vignettes will feature patients with and without nocipalstic pain. Initially, two experts will evaluate and characterize which vignettes concern patients with nociplastic pain.

Next, a team of physiotherapists with knowledge of chronic pain and CS will evaluate vignettes twice according to the IASP criteria. There will be an interval of 1 month between the two measurements. One month later, the evaluation will be repeated. The investigators will design an Android application "Algo (s) rithm" to enter the questions of the algorithm. In the second phase, Algo (s)rithm app will use to evaluate patients with chronic pain (including patients with fibromyalgia) and healthy. The investigators will compare the result with PPT measurements in the same population.In the present study the inter-rater and test-retest reliability, criterion validity, construct validity will be examined.
