Paraplegia, or paraparesis, is an impairment in motor or sensory function of the lower extremities. The word comes from Ionic Greek ( παραπληγίη ) "half-stricken". [ citation needed ] It is usually caused by spinal cord injury or a congenital condition that affects the neural (brain) elements of the spinal canal .
A person's level of injury is defined as the lowest level of full sensation and function. [11] Paraplegia occurs when the legs are affected by the spinal cord damage (in thoracic, lumbar, or sacral injuries), and tetraplegia occurs when all four limbs are affected (cervical damage). [12] SCI is also classified by the degree of impairment.
Paralysis. Specialty. Neurology, neurosurgery, psychiatry. Paralysis (pl.: paralyses; also known as plegia) is a loss of motor function in one or more muscles. Paralysis can also be accompanied by a loss of feeling (sensory loss) in the affected area if there is sensory damage. In the United States, roughly 1 in 50 people have been diagnosed ...
Neurology. Symptoms. Loss of motor skills on one side of body. Causes. Stroke. Hemiparesis, also called unilateral paresis, is the weakness of one entire side of the body (hemi- means "half"). Hemiplegia, in its most severe form, is the complete paralysis of one entire side of the body.
Hereditary spastic paraplegia (HSP) is a group of inherited diseases whose main feature is a progressive gait disorder. The disease presents with progressive stiffness (spasticity) and contraction in the lower limbs. [1] HSP is also known as hereditary spastic paraparesis, familial spastic paraplegia, French settlement disease, Strumpell ...
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. hemisection of the spinal cord resulting in paralysis and loss of proprioception on the same (or ipsilateral) side as the injury or lesion, and loss of ...
The U.N. agency estimates that 1 in 200 polio cases results in permanent paralysis, usually of the legs. Among children who are paralyzed, up to 10% die when their breathing muscles are paralyzed.
Other causes include vasculitis, polycythemia, sickle cell disease, decompression sickness, and collagen and elastin disorders. [1] A thrombus in the artery of Adamkiewicz can lead to an anterior spinal syndrome. This is the most feared, though rare complication of bronchial artery embolization done in massive hemoptysis. [6]
