Quadriplegia is defined as a loss of function in the legs, trunk, and arms, resulting from injury or illness that affects the spinal cord. This condition often leads to a complete or partial inability to move or feel in these areas, due to disruption in the signals between the brain and the body. It is commonly caused by spinal cord injuries or diseases that impact the nerve pathways responsible for motor function and sensation.
