Spinal cord injury can cause partial or complete paralysis below the injury level. Dr. Anand Karnam and Dr. Harisha explain the classification system, what determines recovery potential, and the rehabilitation approach.
Key Points
- Spinal cord injuries are classified by level (cervical, thoracic, lumbar) and completeness — both determine recovery potential.
- The ASIA impairment scale grades injury from A (complete — no motor/sensory below injury) to E (normal).
- Early rehabilitation (within 24–72 hours) prevents complications: pneumonia, pressure sores, DVT, contractures.
- Incomplete injuries have significant recovery potential — aggressive early physiotherapy is critical.
- FES (functional electrical stimulation) and robotic gait training are advancing recovery possibilities significantly.

"Spinal cord injury rehabilitation is one of the most technically demanding and emotionally important things I do. The family who commits to intensive rehabilitation — visits every day, learns the exercises, manages positioning — gets a very different outcome from the one who waits."
Spinal cord injury (SCI) occurs when damage to the spinal cord — from trauma (road accidents, falls, sports injuries), disease (tumour, transverse myelitis, ischaemia), or surgery — interrupts the transmission of motor and sensory signals between the brain and the body below the injury level. In India, road traffic accidents are responsible for the majority of traumatic SCI, with young working-age men disproportionately affected. The physical, psychological, and socioeconomic consequences are profound — making early, comprehensive, specialist rehabilitation essential.
Classification: Complete vs Incomplete Injury
The ASIA (American Spinal Injury Association) Impairment Scale classifies injury severity: ASIA A (complete): No motor or sensory function below the injury level, including the sacral segments (S4-S5) — no anal sensation or voluntary anal contraction. Below the injury level, everything is paralysed. ASIA B (sensory incomplete): Some sensory preservation below the injury level including sacral segments, but no motor function. ASIA C and D (motor incomplete): Motor function is preserved below the level — graded by strength. ASIA D means most key muscles below the level can work against gravity. ASIA E: Normal function.
What Determines Recovery
Completeness of injury at 72 hours is the most important prognostic factor — complete injuries (ASIA A) rarely recover motor function below the level; incomplete injuries have significantly better potential. Injury level: cervical injuries (above C4) affect breathing; lower injuries spare the diaphragm. Neurological recovery continues for 6–24 months — rehabilitation must be intensive during this period.
Rehabilitation Goals
Physiotherapy: maintaining joint range of motion; strengthening of preserved and recovering muscles; training transfers, wheelchair mobility, and gait (with assistive devices for incomplete SCI); respiratory physiotherapy for cervical injuries. Pressure ulcer prevention (repositioning every 2 hours). Bladder and bowel management. Spasticity management (physiotherapy, baclofen, botulinum toxin). Psychological support. Assistive technology — wheelchairs, standing frames, FES systems. Sri Anand CNC, Chanda Nagar, Hyderabad. Call +91 90633 66983.
