What is the primary purpose of the slump test?

• A. To measure hamstring flexibility
• B. To assess neural tissue mechanosensitivity and possible lumbar nerve root involvement
• C. To evaluate hip joint range of motion
• D. To test cervical spine mobility

Answer: (B)

Neural tissue mechanosensitivity and lumbar nerve root involvement are what the slump test is designed to uncover. By guiding the patient into seated spinal flexion, then adding neck flexion, knee extension, and ankle dorsiflexion, the test tensions the nerves along the spine and down the leg. If symptoms are reproduced or intensified with this systematic neural loading, it suggests that the neural tissue is sensitive to tension and that a lumbar nerve root or neural pathway irritation may be contributing to the pain. This helps distinguish radicular or neurogenic pain from purely musculoskeletal issues. It’s not a measure of hamstring flexibility, hip range of motion, or cervical spine mobility; those areas are assessed with different tests.
