A spinal cord injury occurs when there is damage to the spinal cord, which is a bundle of nerves that runs down the back and connects the brain to the body. This injury can result from trauma, such as a car accident or a fall, and can lead to loss of movement, sensation, or function below the injury site. The severity of the injury can vary, affecting different parts of the body. The effects of a spinal cord injury depend on the location and extent of the damage. Injuries in the neck area, known as cervical spinal cord injuries, can lead to paralysis in all four limbs, while injuries in the lower back, or lumbar spinal cord injuries, may affect only the legs. Rehabilitation and therapy are often necessary to help individuals regain as much function as possible.
