Condition

Reflex Sympathetic Dystrophy Syndrome (Rsds)

Treatment

Infrared Imaging

Study Summary

The goal of this interventional study is to explore the use of InfraRed (FLIR) imaging in determining pain intensity and severity in newly diagnosed complex regional pain syndrome patients. The main questions it aims to answer are:

Question 1: Can Infrared (FLIR) imaging be used to determine the severity of CRPS in newly diagnosed patients? Question 2: Is there any correlation with the quantification of 'the Δ thermal index value' measured by FLIR imaging with pain intensity (NRS) in newly diagnosed patients? Question 3: Is there any correlation between the quantification of 'the Δheat index value' measured by FLIR imaging between the two extremities with the severity (the severity score for CRPS) in newly diagnosed patients? Participants will have a picture of their foot taken using the forward looking infrared (FLIR) camera and answer questionnaires regarding their pain and complex regional pain syndrome (CRPS).

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • The patient is between 18 and 85 years old

  • Providing CRPS diagnostic criteria using the Budapest Clinical Diagnostic Criteria.

  • The patients affected with CRPS in a unilateral limb

  • The patient has had pain and other symptoms for more than 3 months

Exclusion

Exclusion Criteria:

  • Patients with suspected disc herniation, spinal stenosis, myelopathy, and suspectedradiculopathy in detailed examinations and examinations (MRI, CT).

  • Systemic or local infection

  • Malignancy

  • Pregnancy

  • Uncontrollable medical and psychiatric condition

  • The patients diagnosed with dysautonomia, sympathetic dysfunction(such as Raynauddisease or Buerger disease), and patients on vasoactive drugs, the mechanism ofaction is directly on the vasculartone.

Study Description

Patients with CRPS have a better chance of remission if they receive treatment early in the disease's progression. Similarly, determining the severity of the disease early on is critical for planning effective treatment to prevent progression. The lack of an objective method for determining the severity and potential progression of CRPS is a major reason for postponing CRPS treatment.

The purpose of this interventional study is to investigate whether or not near-infrared (FLIR) imaging can be used to evaluate the level of pain experienced by patients who have recently been diagnosed with complex regional pain syndrome. Its primary goals are to provide responses to the following questions:

Question 1: Can Infrared (FLIR) imaging be used to determine the severity of CRPS in newly diagnosed patients? Question 2: Is there any correlation with the quantification of 'the Δ thermal index value' measured by FLIR imaging with pain intensity (NRS) in newly diagnosed patients? Question 3: Is there any correlation between the quantification of 'the Δheat index value' measured by FLIR imaging between the two extremities with the severity (the severity score for CRPS) in newly diagnosed patients? The forward looking infrared (FLIR) camera will be used to take a picture of each participant's foot, and they will also be asked to fill out questionnaires regarding their level of pain and complex regional pain syndrome (CRPS).

If infrared (FLIR) imaging can be used to determine the severity of CRPS in newly diagnosed patients, and if there is a correlation between the quantification of the heat index value' measured by FLIR imaging and the severity score for CRPS in newly diagnosed patients, the findings of this study could be useful in daily clinical practice.
