Brown-Séquard syndrome (also known as Brown-Séquard's hemiplegia, Brown-Séquard's paralysis, hemiparaplegic syndrome, hemiplegia et hemiparaplegia spinalis, or spinal hemiparaplegia) is caused by damage to one half of the spinal cord, i.e. spinal shock can last from several hours to around 6 weeks THEN: reflexes below the level of spinal cord injury become hyperresponsive . He is an internationally recognised Clinician Educator with a passion for helping clinicians learn and for improving the clinical performance of individuals and collectives. Spinal shock defined as temporary loss of spinal cord function and reflex activity below the level of a spinal cord injury. This may last for hours to weeks post-injury. Hypotension in a trauma patient is hemorrhagic until proven otherwise. Spinal stenosis is a term used to describe a narrowing of the spinal canal.

Spinal cord compression (SCC) results from processes that compress or displace arterial, venous, and cerebrospinal fluid spaces, as well as the cord itself. Functional recovery may improve after spinal shock resolves.
