Effects of a Spinal Cord Injury
A spinal cord injury can cause a loss of sensation, a loss of motor function and strength, or both. If an injury completely severs the spine, then the nerve endings below the injury site will no longer transmit signals to the brain. A complete injury like this will lead to a permanent loss of function and sensation in the affected areas.
If an injury does not completely sever the spinal cord, some signals may still work, and the victim may experience reduced sensation, strength, or function, or a combination of these symptoms. Unlike the rest of the human body, the spinal cord cannot self-heal. Any injury to the cord is permanent, as are the resulting symptoms.
Considering that motor vehicle accidents are responsible for more than half of all recorded spinal injuries, the best way to prevent such injuries is to drive safely, refrain from driving under the influence of alcohol, and wear your seatbelt. Limiting risky behavior is a personal choice, but it is crucial to understand the risks you are assuming if you choose to partake in extreme sports or dangerous recreational activities.
