Brief summary
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
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.
Interventions
DIAGNOSTIC_TESTAlgo(s)rithm/ IASP clinical criteria
IASP clinical criteria for identifying nociplastic pain. The criteria is completed by the healthcare professional and includes questions about the patient's clinical picture.
DIAGNOSTIC_TESTPressure Pain Threshold
The pain pressure threshold (PPT) is used to measure pain sensitivity in body areas. The test quantifies the minimum amount of pressure in a given area, during an increasing skin pressure stimulus, which is capable of altering the feeling of pressure in pain.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| IASP clinical criteria | through study completion, an average of 1 year | IASP clinical criteria for indentifying nociplastic pain. The criteria are completed by the healthcare professional and includes questions about the patient's clinical picture. |
| Pressure Pain Thresholds PPT | through study completion, an average of 1 year | The pain pressure threshold (PPT) is used to measure pain sensitivity in body areas. The test quantifies the minimum amount of pressure in a given area, during an increasing pressure of the skin, which is able to change the feeling of pressure in the pain. Measurements will be performed according to protocols used in previous studies. |
