The Relationship Between Magnetic Resonance Imaging (MRI) Scores and Sensory Testing in Axial Spondyloarthritis

August 21, 2021 updated by: Marmara University

Investigation of the Relationship Between Sacroiliac Magnetic Resonance Imaging (MRI) Scores and Quantitative Sensory Testing in Patients With Axial Spondyloarthritis

Axial spondyloarthritis is one of the most common rheumatic diseases and chronic pain and morning stiffness are the main complaints of these patients. Central sensitization is defined as increased response to normal or sub-threshold stimuli of central nervous system and its close relationship with many rheumatological diseases has been demonstrated in several studies. There is no method for the diagnosis of central sensitization is accepted as a gold standard. The clinical scales and quantitative sensory testing (QST) widely is used for this purpose widely. The most commonly used QST types include pressure pain threshold (PPT), temporal summation (TS) and conditioned pain modulation (CPM). The well-known scale used for the evaluation of central sensitization is the Central Sensitization Inventory (CSI) , developed in 2011 for detect central sensitization in chronic pain patients. In this study, it was aimed to investigate the relationship between QST and CSI and sacroiliac MRI changes.

Detailed Description

Central sensitization is hypersensitivity and increased response to normal/painless stimuli due to dysfunction in endogenous pain pathways. Quantitative sensory testing is frequently used to detect pain sensitization, and pressure pain threshold (PPT) and temporal summation (TS) are often preferred for this purpose. Recently, in addition to these methods, conditional pain modulation (CPM), in which descending pain pathways are tested, is also preferred. With PPT and TS measurement, local/generalized sensitivity increase can be detected in patients who develop pain sensitization. Observation of increased nociceptor response and decrease in pressure pain threshold in the tissue damaged area is interpreted in favor of peripheral sensitization, while obtaining a similar response in adjacent or distant areas is defined as generalized increased sensitivity. Although it is known that local hyperalgesia is one of the main findings of inflammation, studies that have shown this quantitatively are limited. Inflammatory lesions are observed in patients with axial spondyloarthritis, especially in the active stages of the disease, and the relationship of these lesions with PPT, TS and CPM values and pain sensitization is unknown. Therefore, in this study, it was planned to investigate the relationship of inflammatory and structural lesions detected by sacroiliac MRI with regional PPT,TS, CPM and pain sensitization in patients diagnosed with axSpA.

Patients
Patients with Axial SpondyloArthritis
Diagnostic test: Central Sensitization Inventory
Standardized questionnaire to determine the level of central sensitization
Other Names:
  • CSI
Diagnostic test: Pressure pain threshold
The sacroiliac PPT scores will be obtained bilaterally from four measurement points; the first point is located 1 cm medially and caudally from spina iliaca posterior superior (SIPS) and 3 more laterally, medially and cranially.The left trapezius muscle will be used to evaluate distant control point .The 1 cm2 algometer probe will be placed vertically in the each selected point and pressure will be increased with 0.1 kg/sc until the participant reporting pressure became painful. The pressure value at which the pain is first felt will be accepted as the PPT of that point.
Other Names:
  • PPT
Other: Spondyloarthritis Research Consortium of Canada scoring system
SPARCC scoring consists of two subcomponents to detect sacroiliitis activation and structural damage. In the short tau inversion recovery (STIR) sequence, 6 consecutive coronal sections will be examined and the signal increase will be scored as 0 = normal signal and 1 = increased signal. In this way, the maximum score can be 12 in a single coronal section. Evaluations Total maximum score of 72 in 6 consecutive coronal sections. In structural scoring, similar to sacroiliitis scoring, the SI joint is divided into four quadrants to evaluate whether there is fatty change, erosion, backfill and ankylosis. Each lesion is scored as 0=absent or 1=present. In this way, fatty change and erosion can be scored between 0-40 and backfill and ankylosis can be scored between 0-20 in 5 consecutive sections in total scoring.
Other Names:
  • SPARCC
Diagnostic test: Temporal Summation
TS will be evaluated over the trapezius muscle and sacroiliac joints with manuel algometer. In the evaluation of TS, a pressure as much the PPT value of each point will be applied with pain pressure algometer ten times with a 1-second interstimulus interval. Patients will be asked to rate their pain using on a 0 to 10 visual analogue scale (VAS) at 0, 5, and 10 seconds. TS will be calculated by subtracting the rating at 0 seconds from the rating at 10 seconds. The point that is located 1 cm medially and caudally from SIPS was used for SI joint TS measurement on both sides.
Other Names:
  • TS
Diagnostic test: Conditioned pain modulation
First stimulus will be applied to trapezius with the pressure that induced a pain intensity of 4 point on a 10 point VAS as called a test stimulus. After that the right hand of the patient will be immersed in 7 Celsius water for 20 seconds to create a conditioning stimulus. Second test stimulus with the same intensity of first one will be applied to trapezius after the conditioning stimulus and patients will be asked to rate their pain. If the patients cannot hold their hand in the water for 20 seconds, the test stimulus will be applied immediately after the patients removed their hands out of water. The ratio between the first and second VAS values multiplied by 100 will be defined as CPM score

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Central Sensitization Inventory (CSI)
Time Frame: 1 months
25 somatic and psychosocial symptoms, which are frequently found in patients with central sensitization in part A, are questioned. In part B, the presence of diseases whose relationship with central sensitization is well defined is questioned in the patient without participating in scoring. Central sensitization is assumed in patients who score 40 or more over 100 points. As the score increases, the severity of sensitization is considered to increase.
1 months
Pressure pain threshold (PPT)
Time Frame: 1 months
The sacroiliac PPT scores were obtained from four measurement points; the first point was located 1 cm medially and caudally from spina iliaca posterior superior (SIPS) and 3 more laterally, medially, and cranially. Lower scores are interpreted in favor of increased pain sensitization.
1 months
Temporal summation (TS)
Time Frame: 1 months
TS will be evaluated over the trapezius muscle and sacroiliac joints with manuel algometer. In the evaluation of TS, a pressure as much the PPT value of each point will be applied with pain pressure algometer ten times with a 1-second interstimulus interval. Patients will be asked to rate their pain using on a 0 to 10 visual analogue scale (VAS) at 0, 5, and 10 seconds. TS will be calculated by subtracting the rating at 0 seconds from the rating at 10 seconds. The point that is located 1 cm medially and caudally from SIPS was used for SI joint TS measurement on both sides. As the score increases, the severity of sensitization is considered to increase.
1 months
Conditioned pain modulation (CPM)
Time Frame: 1 months
First stimulus will be applied to trapezius with the pressure that induced a pain intensity of 4 point on a 10 point VAS as called a test stimulus. After that the right hand of the patient will be immersed in 7 Celsius water for 20 seconds to create a conditioning stimulus. Second test stimulus with the same intensity of first one will be applied to trapezius after the conditioning stimulus and patients will be asked to rate their pain. If the patients cannot hold their hand in the water for 20 seconds, the test stimulus will be applied immediately after the patients removed their hands out of water. The ratio between the first and second VAS values multiplied by 100 will be defined as CPM score. Higher scores indicate better descending pain inhibition.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
