Validation of the Central Sensitisation Algorithm: Vignette Methods and Utilization to Patients With Chronic Pain
Study Details
Study Description
Brief Summary
This protocol will report on the validation process of the Central Sensitisation Algorithm. 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 pain. The vignettes will feature patients with and without Central Sensitisation (CS). Initially, two experts will evaluate and characterize which vignettes concern patients with CS.
Next, a team of physiotherapists with knowledge of chronic pain and CS will evaluate vignettes twice: 1) according to their clinical reasoning and 2) according to the algorithm. There will be an interval of at least 2 weeks between the two measurements. One month later, the evaluation according to the Algorithm 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.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Chronic Pain Patients Adult patients 18-65 years, with chronic pain lasting for 3 or more months, with a pain intensity of at least 3 on a 0-10 numerical pain rating scale on most days. |
Diagnostic Test: Algo(s)rithm
Specialized Algorithm for the categorization of Central Sensitisation. The algorithm is completed by the healthcare professional and includes questions about the patient's clinical picture.
Diagnostic Test: Pressure Pain Threshold
The pain pressure threshold (PPT) is used to measure the sensitivity of specific 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.

Outcome Measures
Primary Outcome Measures
- Algo(s)rithm [through study completion, an average of 1 year]
Specialized Algorithm for the categorization of Central Sensitisation. The algorithm is 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 the sensitivity of specific 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 (Correa-Rodriquez et al. 2019; Coronado et al. 2018; Wang-Price et al. 2019; Jakorinne et al. 2018; Balaguier et al. 2016)
