A spinal cord injury occurs when the spinal cord is damaged, often from an impact, which can lead to paralysis below the site of injury. In the US there are 12,000 to 15,000 spinal cord injuries per year, most occurring in young people aged 15 to 35. Recovery depends on the severity of injury but may involve surgery, rehabilitation, and care from medical professionals like physical therapists and psychologists. An example is NFL player Kevin Everett who suffered a spinal cord injury during a game but was able to move his limbs a few days later, showing signs of potential recovery.
