Which test is most sensitive for detecting cervical radiculopathy?

• A. Spurling's test
• B. ULTT (Upper Limb Tension Test)
• C. Shoulder abduction test
• D. Median nerve compression test

Answer: (B)

Focusing on sensitivity helps you understand why this test stands out. Sensitivity is about catching as many true cases as possible; a highly sensitive test gives a negative result that meaningfully reduces the likelihood of disease when the result is negative (SnNout concept). The Upper Limb Tension Test works by placing controlled tension along the entire neural pathway from the cervical roots to the hand. If cervical nerve roots are irritated, this neural strain often reproduces the patient’s dermatomal symptoms, and it tends to do so across different arm positions that stress the nerves rather than just a single joint maneuver. Because it systematically loading the nerve pathways can reveal irritation that local provocative tests might miss, it tends to identify cervical radiculopathy more consistently than other tests. Spurling’s test focuses on foraminal compression with neck movements. It can be very specific when positive, but it misses many cases, so its sensitivity is lower. The shoulder abduction test can alleviate symptoms by reducing neural tension, but it isn’t as reliable for detecting radiculopathy itself. The median nerve compression test targets peripheral nerve entrapment in the arm or forearm, not cervical root irritation, so it isn’t appropriate for detecting radiculopathy at the cervical level. So, the Upper Limb Tension Test is the best choice for sensitivity in detecting cervical radiculopathy.
