Introduction:
A few spinal manipulation techniques use paraspinal surface thermography as an examination tool that informs clinical-decision making; however, inter-examiner reliability of this interpretation has not been reported. The purpose of this study was to report inter-examiner reliability for classifying cervical paraspinal thermographic findings.
Methods:
Seventeen doctors of chiropractic self-reporting a minimum of 2 years of experience using thermography classified thermographic scans into categories (full pattern, partial +, partial, partial -, and adaptation). Kappa statistics (k) were calculated to determine inter-examiner reliability.
Results:
Overall inter-examiner reliability was fair (k=0.43). There was good agreement for identifying full pattern (k=0.73) and fair agreement for adaptation (k=0.55). Poor agreement was noted in partial categories (k=0.05-0.22).
Conclusion:
Inter-examiner reliability demonstrated fair to good agreement for identifying comparable (full pattern) and disparate (adaptation) thermographic findings; agreement was poor for those with moderate similarity (partial). Further research is needed to determine whether thermographic findings should be used in clinical decision-making for spinal manipulation.

Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
