Summary
The Spurling test shows low sensitivity but high specificity for diagnosing cervical radiculopathy. While not ideal for screening, it is a valuable tool for confirming this condition.
Area of Science:
- Neurology
- Orthopedics
- Physical Examination
Background:
- The Spurling test is a commonly used physical examination for cervical radiculopathy.
- Limited data exists regarding the diagnostic accuracy of the Spurling test.
Purpose of the Study:
- To evaluate the sensitivity and specificity of the Spurling test in diagnosing cervical radiculopathy.
Main Methods:
- A cross-sectional study involving 255 patients undergoing electrodiagnosis for upper extremity nerve disorders.
- The Spurling test was administered, and results were analyzed using chi-squared analysis.
- Sensitivity and specificity were calculated based on electrodiagnostic findings.
Main Results:
- The Spurling test demonstrated a sensitivity of 30% and a specificity of 93% for cervical radiculopathy.
- Positive Spurling test results varied across diagnostic groups, being highest in certain radiculopathy (40%).
Conclusions:
- The Spurling test is not a sensitive diagnostic tool for cervical radiculopathy.
- However, its high specificity makes it clinically useful for confirming the diagnosis when positive.
