Which examination test is commonly used to reproduce radicular symptoms by nerve root tension?

Radicular symptoms arise when the nerve roots along the lumbar spine are irritated or compressed. The straight leg raise test directly assesses nerve root tension by passively lifting the straight leg, which lengthens the spinal nerves and sciatic nerve. If disc herniation or nerve irritation is present, this stretching often reproduces the characteristic shooting pain down the leg, sometimes radiating below the knee. This direct elicitation of radicular-type pain is what makes it the best choice for assessing nerve root tension. The other tests target different conditions: the Kernig sign looks for meningeal irritation rather than nerve root tension; Phalen test screens for carpal tunnel syndrome; and the McMurray test checks for meniscal tears in the knee.
