Which assessment technique is commonly used to evaluate lumbar radiculopathy?

The straight-leg raise test is a widely recognized assessment technique specifically used to evaluate lumbar radiculopathy. This test is effective because it helps to determine if there is nerve root involvement related to compression or irritation, often suggested by conditions such as a herniated disc or spinal stenosis.

During the straight-leg raise test, the patient is asked to lie flat while the examiner lifts the leg of the affected side straight up to a point where pain is reproduced, usually around 30 to 70 degrees of elevation. If the patient experiences radiating pain down the leg, it indicates positive findings that suggest lumbar nerve root involvement. This response can correlate with conditions like sciatica, helping clinicians to localize the area of nerve irritation or compression.

The other assessment techniques serve different purposes. Brudzinski's sign is primarily used to assess for meningeal irritation and is thus more relevant in conditions like meningitis. Spurling's test is utilized to evaluate cervical radiculopathy rather than lumbar issues, as it involves the cervical spine. The Neer test is focused on shoulder pathologies, particularly rotator cuff injuries, and is unrelated to lumbar radiculopathy. Thus, the straight-leg raise is the most appropriate and effective technique for evaluating lumbar rad
