Which set of tests are described as assessing spine mobility?

• A. Slump test
• B. SLR
• C. Gillet's march test
• D. All of the above

Answer: (D)

Movement tests for the spine are not limited to isolating the vertebral segments; they rely on how the spine, pelvis, and sacroiliac region move in coordination with limb movements. In the slump test, the patient sits and allows the spine to flex, then progressively unloads neural tissue with knee extension and ankle movements; this sequence depends on the thoracic and lumbar regions sliding and flexing to load and release neural structures, so spinal mobility is central to the test. The straight leg raise also requires the hip to flex while maintaining or adjusting lumbar spine posture to tension the neural tissues along the sciatic pathway, making lumbar and lumbosacral mobility a factor in what is produced. Gillet’s march assesses how the pelvis and sacroiliac joints move relative to the lumbar spine as the patient marches, directly evaluating lumbopelvic motion and how SI joint movement interacts with spinal mechanics. Since each test involves movement that engages spine or lumbopelvic mobility to reproduce symptoms or assess motion, all of them describe spine mobility. Therefore, all of the above is the best answer.
