A 64-slice CT with reconstructions does not entirely rule out ligamentous injury leading to instability, but is a practical means of identifying the majority of C-spine injuries in obtunded patients. MR C-spine has frequent false-positives, limiting its usefulness. [citation needed] In these cases, a consultation with a Spine Surgery specialist ...
Repetitive nerve stimulation is a variant of the nerve conduction study where electrical stimulation is delivered to a motor nerve repeatedly several times per second. By observing the change in the muscle electrical response (CMAP) after several stimulations, a physician can assess for the presence of a neuromuscular junction disease, and differentiate between presynaptic and postsynaptic ...

If there is a stenosis in the spine, there will be a damped, delayed response in the lumbar pressure, thus a positive Queckenstedt's maneuver. Nowadays this test has been made mostly superfluous by superior imaging modalities like MRI and CAT. [1] The test is named after Hans Heinrich Georg Queckenstedt who described it in 1916. [2]
