Queckenstedt's maneuver is a clinical test, formerly used for diagnosing spinal stenosis. The test is performed by placing the patient in the lateral decubitus position, thereafter the clinician performs a lumbar puncture. The opening pressure is measured.

The person is usually placed on their side (left more commonly than right). The patient bends the neck so the chin is close to the chest, hunches the back, and brings knees toward the ...
Quincke's puncture" is a somewhat outdated eponym for lumbar puncture, [4] [5] used for the examination of the cerebrospinal fluid in numerous diseases such as meningitis and multiple sclerosis. In 1893 he described what is now known as idiopathic intracranial hypertension, which he labeled "serous meningitis". [6]
An epidural blood patch (EBP) is a surgical procedure that uses autologous blood, meaning the patient's own blood, in order to close one or many holes in the dura mater of the spinal cord, which occurred as a complication of a lumbar puncture or epidural placement. [1] [2] The punctured dura causes cerebrospinal fluid leak (CSF leak). [1]
For those children with spinal cord diseases, lumbar puncture may damage the spinal cord due to possibility of tethered spinal cord syndrome where the spinal cord is located below than the usual spinal termination level. [3] Therefore, lumbar puncture should be done at the lowest position as possible for such cases. However, spinal cord injury ...
Radionuclide cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...

The test involves removing 30–50 ml of CSF through a lumbar puncture, after which motor and cognitive function is clinically reassessed. [1] The name "Fisher test" is after C. Miller Fisher , a Canadian neurologist working in Boston, Massachusetts, who described the test.
