Persons affected by spinal cord injury lose their independence and have a severely deteriorated quality of life due to the functional impairments in their upper and lower limbs.

When the spinal cord, a thin bundle of nervous tissue, is damaged, signals from the brain that usually travel down the nerves spinal cord to the muscles are interrupted. The nerve fibers in these descending pathways are broken or destroyed and they undergo reorganization to regenerate essential pathways such as those involved
