Fallacies in Interpretation of Queckenstedt's Test

The rise and fall of Queckenstedt's test between 1916 and 1970, a milestone in spinal cord diagnostics and why it matters

“…Still, to our best knowledge, findings from myelography and Queckenstedt's test overlap to a large extent. Most failures of Queckenstedt's test were related to tumor at the cranio‐cervical junction and the lumbosacral cord, due to the larger spinal canal size there, as well as small tumors that were not affecting CSF flow [ 39 , 40 , 41 ]. Several studies advanced the value of Queckenstedt's test through refinement and advanced recording methods.…”

Queckenstedt’s test repurposed for the quantitative assessment of the cerebrospinal fluid pulsatility curve

“…One cause for the drop of interest in QT was its low to moderate sensitivity to detect spinal cord compression based solely on absolute values of mean CSFP rise from the resting state to peak QT [ 15 , 45 , 47 ]. In a cohort of patients with chronic spinal canal narrowing, we found that RPPC-Q was more sensitive to detect effective stenosis than rise of CSFP during Queckenstedt's test [ 28 ].…”

Study protocol for an observational study of cerebrospinal fluid pressure in patients with degenerative cervical myelopathy undergoing surgical deCOMPression of the spinal CORD: the COMP-CORD study

“…The evaluation of CSFP and especially Queckenstedt's test has a longstanding tradition in the diagnosis of spinal neurological disorders. When reviewers reported about low sensitivity of CSFP for spinal obstruction compared with myelography and intraoperative findings, they mostly referred to lesions at or above the foramen magnum, 50 which is indeed not an ideal subject CSFP analyses. 51 Despite all obstacles, 39 CSFP analysis was considered a useful method for the diagnosis of cervical obstruction before the introduction of myelography.…”
