Spinal Cord Injury: Understanding Paralysis and Hope for Recovery
By Anshika
An in-depth look at spinal cord injury — mechanisms, levels of injury, current treatments, and groundbreaking research in neural regeneration.
Spinal cord injury (SCI) is damage to the bundle of nerves and nerve fibers that transmits signals between the brain and the rest of the body. It is one of the most devastating neurological injuries, affecting approximately 15 million people worldwide.
Classification by Level
**Cervical (Neck) Injuries:** Quadriplegia/Tetraplegia — affects all four limbs.
**Thoracic (Upper Back) Injuries:** Paraplegia — affects the trunk and legs but arm function is preserved.
**Lumbar and Sacral Injuries:** Affects hip flexion and leg movement.
Acute Treatment
Emergency management involves spinal immobilization, maintaining blood pressure, early surgical decompression (within 24 hours), and in some cases, high-dose methylprednisolone.
Rehabilitation
Comprehensive rehabilitation includes physical therapy, occupational therapy, bowel and bladder management, respiratory therapy (for cervical injuries), and psychological support.
Cutting-Edge Research
Stem cell therapies, epidural stimulation enabling standing and stepping in complete paralysis, brain-computer interfaces, and neuroprotective drugs are all advancing the field.
