Tetraplegia is also known as quadriplegia which is the dysfunction or loss of motor and or sensory function in the cervical area of your spinal cord.
The loss of motor function can present as either paralysis or weakness which can lead to partial loss or total loss of function in your legs, arms, trunk and pelvis.
The words "tetraplegia" and "quadriplegia" mean the same thing which is paralysis below the neck that affects all of a person's limbs.
The reason there's 2 terms that mean the same thing is because of differences in the ancient languages.
The Greek word for four is “Tetra.” Combine that with “plegia” and you have a word with Greek roots for both halves.
The British have also always used the term “Tetraplegia” for four-limb paralysis, so they are not combining Latin and Greek words.
Around 80 percent of people with incomplete spinal cord injuries can regain some ambulatory ability after going through a rehabilitation program.
Although most of the people can walk non functionally and require a walking device.
There is no cure for tetraplegia, so instead treatment focuses on addressing symptoms and also improving a persons quality of life.
