CLINICAL ASPECT OF SPINAL MOTOR SYSTEM - THE BROWN SEQUARD SYNDROME

Brown-Séquard syndrome, also known as Brown-Séquard's

hemiplegia and Brown-Séquard's

paralysis, is a loss of sensation and motor function (paralysis and anesthesia) that is caused by the lateral hemisection

(cutting) of the spinal

cord. This may be

seen most often in the cervical (neck) or thoracic spine. Other synonyms are hemiparaplegic syndrome, hemiplegia ethemiparaplegiaspinalis,

and spinal hemiparaplegia. Brown-Séquard syndrome is

characterized by loss of motor function(i.e.

hemiparaplegia), loss of vibration sense and fine touch, loss ofproprioception (position sense), loss

of two-point discrimination, andsigns

of weakness on the ipsilateral (same side) of the spinal injury.
