Tetraplegia - Definition

Ask a question


Tetraplegia, also known as quadriplegia, is a state of paralysis affecting all four limbs. This is due to a lesion in the spinal cord located high up on the spinal column, above the fifth cervical vertebra, mostly due to trauma or an accident. This condition affects the spinal cord and thus the nerve impulse transmission is damaged in the nerve roots below the lesion site. Paralysis, defining the total inability to move, is accompanied by loss of sensation in the same areas, involving the capacity to feel pain and touch. This leads to severe disability, with the patient becoming dependent on others for the slightest day-to-day gesture.
