Which test is most appropriate to differentiate neural tissue involvement from hamstring tightness?

• A. Kemp's test
• B. Stork standing test
• C. Slump test
• D. Straight leg raise

Answer: (C)

Neural tissue mobility is what this test isolates. The slump test places the nervous system under controlled tension along the posterior chain by slumping the spine, maintaining neck position, then extending the knee and sometimes adding ankle dorsiflexion. The key is that you can modulate neural tension with neck position: symptoms that are produced when the knee is extended but relieved when the neck is extended or later relaxed point to neural tissue involvement rather than muscle (hamstring) tightness. If the problem were purely hamstring tightness, changing neck position wouldn’t relieve the symptoms, because the limitation is at the muscle level, not in the neural pathway. Other tests don’t target neural tissue in this differentiating way: some primarily assess hamstring length or other spinal structures. That’s why the slump test is the most appropriate for distinguishing neural tissue involvement from hamstring tightness.
