Detaillierte Beschreibung
Fibromyalgia is characterized by altered pain processing mechanisms, including impaired descending pain inhibition and central sensitization. Although both mechanisms have been independently associated with symptom severity and functional impairment, their interrelationship and relative contributions to disease impact are not fully understood.
This study aims to examine the associations between conditioned pain modulation, central sensitization symptoms, and fibromyalgia impact. In particular, the study evaluates whether central sensitization symptoms act as a mediator in the relationship between impaired pain modulation and clinical disease burden. Participants with fibromyalgia are assessed using standardized clinical and psychological measures, including the Fibromyalgia Impact Questionnaire, Central Sensitization Inventory, and Hospital Anxiety and Depression Scale. Quantitative sensory testing is performed to evaluate conditioned pain modulation, pressure pain threshold, and temporal summation.Statistical analyses are conducted to explore bivariate associations and to identify independent predictors of fibromyalgia impact. A mediation framework is applied to assess whether central sensitization symptoms explain the relationship between pain modulation and clinical outcomes.

Primäre Ergebnismessungen

Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Conditioned Pain Modulation
Zeitfenster: Baseline
|
Objective determination of the pain modulation phenotype and the severity of central sensitization.
Scores above 100 are considered a normal CPM response; higher scores indicate greater pain inhibition.
|

Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Pressure Pain Threshold
Zeitfenster: Baseline
|
Lower values are associated with pain sensitization
|
Baseline
|
|
Slowly Repeated Evoked Pain Assessment Protocol
Zeitfenster: Baseline
|
The SREP protocol consists of 9 painful stimuli above the pain threshold, each applied to the nail for 5 seconds at approximately 30-second intervals.
|
Baseline
|
|
Central Sensitization Inventory
Zeitfenster: Baseline
|
It is preferred for investigating pain sensitivity through symptoms associated with CS and related comorbidities.
CS severity can be classified into 5 different groups based on the score obtained from Section A of the scale: scores of 0-21 indicate a subclinical level, 22-30 indicate a mild level, 31-37 indicate a moderate level, 38-51 indicate a severe level, and scores above 51 indicate a very severe level of CS .
|
Baseline
|
|
Revised Fibromyalgia Impact Questionnaire
Zeitfenster: Baseline
|
It consists of three sections-daily physical activities, general condition, and symptoms-and a total of 21 questions.
It assesses limitations and functional disability in patients with fibromyalgia.
All questions are rated on a 0-10-point Visual Analog Scale (VAS).
A higher total score indicates an increase in disability associated with fibromyalgia.
|
Baseline
|
|
Self-administered Leeds Assessment of Neuropathic Symptoms and Signs
Zeitfenster: Baseline
|
The Neuropathic Symptoms and Signs Questionnaire is a 7-item self-report questionnaire completed by the individual, scored on a scale of 0 to 24.
A score of 12 or higher indicates the likelihood of neuropathic pain .
|
Baseline
|
|
Tampa Kinesiophobia Scale
Zeitfenster: Baseline
|
A 17-item questionnaire developed to measure the fear of movement and re-injury .
The total score ranges from 17 to 68.
Higher scores are associated with an increase in kinesiophobia.
|
Baseline
|
|
Hospital Anxiety and Depression Scale
Zeitfenster: Baseline
|
It consists of a total of 14 items, with 7 items each for anxiety and depression.
Scores for the anxiety and depression subscales range from 0 to 21. Scores between 8 and 10 indicate moderate symptom presence, while a score greater than 11 indicates anxiety and depression symptoms that likely correspond to a clinical diagnosis.
|
Baseline
|
|
SF-12 Quality of Life Scale
Zeitfenster: Baseline
|
It was developed to assess health-related quality of life.
Two separate scores are obtained: the Physical Component Summary (PCS) and the Mental Component Summary (MCS).
The physical score reflects the individual's perception of overall health, physical limitations, and pain levels.
The mental score, on the other hand, reflects the individual's emotional problems, energy levels, and social activities.
|
Baseline
|
|
Fatigue Severity Scale
Zeitfenster: Baseline
|
This is a 9-item questionnaire in which each item is rated on a scale of 1 to 7; it assesses the severity, frequency, and impact of fatigue on daily life.
The total score ranges from 7 to 63.
As the score decreases, fatigue decreases.
