Tetraplegia in the context of "Spinal cord injury"

A spinal cord injury (SCI) is damage to the spinal cord that causes temporary or permanent changes in its function. It is a destructive neurological and pathological state that causes major motor, sensory and autonomic dysfunctions.

Symptoms of spinal cord injury may include loss of muscle function, sensation, or autonomic function in the parts of the body served by the spinal cord below the level of the injury. Injury can occur at any level of the spinal cord and can be complete, with a total loss of sensation and muscle function at lower sacral segments, or incomplete, meaning some nervous signals are able to travel past the injured area of the cord up to the Sacral S4-5 spinal cord segments. Depending on the location and severity of damage, the symptoms vary, from numbness to paralysis, including bowel or bladder incontinence. Long term outcomes also range widely, from full recovery to permanent tetraplegia (also called quadriplegia) or paraplegia. Complications can include muscle atrophy, loss of voluntary motor control, spasticity, pressure sores, infections, and breathing problems.

The Sea Inside (Spanish: Mar adentro) is a 2004 psychological drama film co-written and directed by Alejandro Amenábar, who also co-produced, scored and edited. It is based on the real-life story of Ramón Sampedro (played by Javier Bardem), who was left quadriplegic after a diving accident, and his 28-year campaign in support of euthanasia and the right to end his life. The film won the Academy Award for Best Foreign Language Film and won the Grand Jury Prize at the 61st Venice International Film Festival.

Sheikh Ahmed Ismail Hassan Yassin (Arabic: الشيخ أحمد إسماعيل حسن ياسين; June 1936 – 22 March 2004) was a Palestinian politician and imam who founded Hamas, an Islamist political and military organization. He also served as the first chairman of the Hamas Shura Council and de facto leader of Hamas since its inception from December 1987 until his assassination in March 2004.

Yassin was born in Ashkelon, in Mandatory Palestine in 1929 or 1936. His family fled or were expelled during the 1948 Palestine War to Gaza City. Yassin, a quadriplegic who was nearly blind, had been reliant on a wheelchair due to a sporting accident at the age of 12.

Paraplegia, or paraparesis, is an impairment in motor or sensory function of the lower extremities. The word comes from Ionic Greek (παραπληγίη)"half-stricken". It is usually caused by spinal cord injury or a congenital condition that affects the neural (brain) elements of the spinal canal. The area of the spinal canal that is affected in paraplegia is either the thoracic, lumbar, or sacral regions. If four limbs are affected by paralysis, tetraplegia or quadriplegia is the correct term. If only one limb is affected, the correct term is monoplegia. Spastic paraplegia is a form of paraplegia defined by spasticity of the affected muscles, rather than flaccid paralysis.

The American Spinal Injury Association classifies spinal cord injury severity in the following manner. ASIA A is the complete loss of sensory function and motor skills below the injury. ASIA B is having some sensory function below the injury, but no motor function. In ASIA C, there is some motor function below the level of injury, but half of the muscles cannot move against gravity. In ASIA D, more than half of the muscles below the level of injury can move against gravity. ASIA E is the restoration of all neurologic function.
