A paraplegic and a quadriplegic are individuals suffering from some sort of damage to the spinal cord, whether it was caused by injury or by congential problems. This damage results in some degree of paralysis, or the inability to move, as well as changes in sensory function. The difference stems from the location and the extent of damage.
Para- being two and quad- being four. Either two limbs or all for limbs are paralyzed. it means that one has lost the use of two limbs
That would be a paraplegic person.
