2. Spinal stenosis - Wikipedia

   en.wikipedia.org/wiki/Spinal_stenosis

   Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]

3. Queckenstedt's maneuver - Wikipedia

   en.wikipedia.org/wiki/Queckenstedt's_maneuver

   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]

4. Lumbar spinal stenosis - Wikipedia

   en.wikipedia.org/wiki/Lumbar_spinal_stenosis

   Forward displacement of a proximal vertebra in relation to its adjacent vertebra in association with an intact neural arch, and in the presence of degenerative changes, is known as degenerative spondylolisthesis, [9] [10] which narrows the spinal canal, and symptoms of spinal stenosis are common. Of these, neural claudication is most common.

5. Romberg's test - Wikipedia

   en.wikipedia.org/wiki/Romberg's_test

   Romberg's test is not a test of cerebellar function, as it is commonly misconstrued. Patients with severe cerebellar ataxia will generally be unable to balance even with their eyes open; [ 6 ] therefore, the test cannot proceed beyond the first step and no patient with cerebellar ataxia can correctly be described as Romberg's positive.

6. Neurogenic claudication - Wikipedia

   en.wikipedia.org/wiki/Neurogenic_claudication

   Less commonly, the cause of spinal stenosis may be present at birth as seen in achondroplasia, spina bifida, and certain mucopolysaccharidoses. [15] In addition to spinal stenosis, other lower back conditions such as spondylosis, tumors, infections and herniated or ruptured discs can cause NC. These conditions contribute to the potential ...

7. Lordosis - Wikipedia

   en.wikipedia.org/wiki/Lordosis

   This allows for a much more efficient walking gait than that of other primates, whose inflexible spines cause them to resort to an inefficient forward-leaning "bent-knee, bent-waist" gait. As such, lordosis in the human spine is considered one of the primary physiological adaptations of the human skeleton that allows for human gait to be as ...
