Foundation

What is Spinal Cord Injury?

Spinal cord injury (SCI) damages the bundle of nerves that carries signals between the brain and the rest of the body. The result is loss of movement, sensation, and body functions below the level of injury.

Two Key Questions

1. How severe?

Complete vs incomplete — determines if any signals get through

2. How high?

Cervical, thoracic, lumbar, sacral — determines which functions are affected

🦽

Tetraplegia

Injury in cervical spine — affects arms, trunk, legs

🪑

Paraplegia

Injury below cervical — affects trunk and legs

🧠 Spinal Cord Basics

Cervical (8)

Thoracic (12)

Lumbar (5)

Sacral (5)

Higher injury = more extensive loss of function. Each vertebral level corresponds to specific muscle groups and sensation.

Classification System

The AIS Scale: What the Grade Means

The ASIA Impairment Scale (AIS) is the international standard for classifying SCI severity. It determines prognosis and guides rehabilitation approach.

Complete

No motor or sensory in S4-S5

Sensory Incomplete

Sensation preserved, no motor below

Motor Incomplete

Most key muscles grade <3/5

Motor Incomplete

Most key muscles grade ≥3/5

Normal

Neurologically intact

👨‍⚕️ Dr. Pandey's Clinical Note

"The AIS grade at 72 hours post-injury is highly predictive of long-term recovery. AIS A patients rarely convert, while AIS B-D patients have significant potential for improvement — especially in the first 6-12 months."

Critical Distinction

Complete vs Incomplete: What Changes?

This single distinction changes everything — from rehabilitation goals to technology choices to recovery expectations.

Complete Injury (AIS A)

No nerve signals cross the injury site. The spinal cord is completely severed or damaged beyond function below that level.

Rehabilitation Goals:

Maximise independence with remaining function
Compensatory strategies (use arms for everything)
Wheelchair skills and transfers
Prevent secondary complications
Adaptive equipment training

Recovery Potential:

Minimal motor recovery below injury level

Incomplete Injury (AIS B-D)

Some nerve signals still get through. The spinal cord is partially damaged but some connections remain intact.

Rehabilitation Goals:

Retrain and strengthen existing connections
Task-specific practice to promote neuroplasticity
Ambulation training (walking potential)
Return to previous level of function
Minimise compensatory strategies

Recovery Potential:

Significant potential — 70-80% may regain walking

Factor	Complete (AIS A)	Incomplete (AIS B-D)
Walking potential	Rare — typically wheelchair dependent	Good — 70-80% may ambulate
Recovery timeline	Plateau at 6-12 months	Continued improvement for years
Therapy approach	Compensatory + prevention	Restorative + task-specific
Technology focus	Adaptive equipment, smart wheelchairs	Exoskeletons, FES, gait training

By Injury Level

Function at Different Spinal Levels

The higher the injury, the more extensive the loss. Here's what function looks like at each level.

C1-C4

High Tetraplegia

Ventilator dependent, minimal arm movement

Tetraplegia

Elbow flexion, no wrist/hand

Tetraplegia

Wrist extension, tenodesis grasp

C7-C8

Tetraplegia

Hand function, independent transfers

T1-T6

Paraplegia

Full arm function, impaired trunk

T7-T12

Paraplegia

Good trunk control, independent

L1-L3

Paraplegia

Hip flexion, knee extension

L4-S1

Cauda Equina

Ankle/foot weakness, bladder issues

📌 Key Point

Even within the same level, function varies. AIS grade and individual factors matter. This is a general guide — your physiotherapist will assess your specific abilities.

Recovery Journey

SCI Rehabilitation Phases

Rehabilitation begins immediately after injury and continues throughout life. Here's what each phase focuses on.

🏥

Acute Phase

Days 1-14

Spinal stabilisation (surgery/collar)
Respiratory care and prevention
Passive range of motion
Pressure relief positioning
Bowel and bladder management

🔄

Rehab Phase

Weeks 2-12

Strengthening of preserved muscles
Mobility and transfer training
Wheelchair skills
ADL training (dressing, bathing)
Family training and home preparation

🏠

Community Reintegration

3+ months

Home modification implementation
Return to work/education planning
Driving assessment
Sports and recreation
Lifelong maintenance programme

Practical Guide

Essential Exercises for SCI Rehabilitation

Exercise selection depends entirely on injury level and completeness. These are examples — always work with your physiotherapist.

💪

Upper Body Strengthening

All levels with arm function

Resistance training for shoulders, chest, and arms — essential for transfers and wheelchair propulsion.

🪑

Pressure Relief Lifts

Paraplegia, low tetraplegia

Lifting body with arms to relieve sitting pressure — prevents pressure sores.

↔️

Weight Shifts

All wheelchair users

Leaning side to side or forward to change pressure points, performed every 15-30 minutes.

🦵

Passive Range of Motion

All levels — caregiver assisted

Gentle movement of legs and feet to prevent contractures and maintain joint health.

🌬️

Breathing Exercises

Cervical and high thoracic

Deep breathing, incentive spirometry to maintain lung function and prevent pneumonia.

🔄

Mat Activities

Varies by level

Rolling, sitting balance, transfers practice on a mat with appropriate support.

⚠️ Critical Safety

Never force movement beyond available range
Monitor for autonomic dysreflexia (sudden hypertension)
Check skin daily for pressure areas
Ensure proper transfer techniques to prevent falls
Watch for shoulder overuse injuries

Modern Approaches

Technology in SCI Rehabilitation

Advanced technology is transforming what's possible for spinal cord injury recovery.

🦿

Exoskeletons

Robotic suits enabling standing and walking

⚡

FES

Functional electrical stimulation for muscle activation

🖥️

Body-weight support

Overhead harness systems for gait training

🧠

BCI

Brain-computer interfaces for control

🦽

Smart wheelchairs

Powered with obstacle avoidance

📱

Telerehab

Remote monitoring and therapy

🎮

VR training

Virtual reality for motivation

🔌

Epidural stimulation

Emerging research therapy

🔬 Dr. Pandey on Technology

"Technology is a tool, not a cure. Exoskeletons and FES are excellent for task-specific practice, but they work best when combined with intensive, goal-directed therapy. At APARC, we integrate technology with hands-on rehabilitation based on each patient's needs."

Common Questions

SCI Rehabilitation FAQ

Answers to questions patients and families ask most frequently.

❓ Will I ever walk again?

This depends entirely on whether your injury is complete or incomplete. For complete injuries, walking is unlikely — focus shifts to independence in a wheelchair. For incomplete injuries, 70-80% regain some walking ability with intensive rehabilitation.

❓ How long does recovery take?

Most motor recovery occurs in the first 6-12 months. However, functional improvements (learning new ways to do things) continue for years. Rehabilitation is a lifelong process of adaptation and maintenance.

❓ Can the spinal cord heal?

Unlike peripheral nerves, the spinal cord does not regenerate spontaneously. Research is ongoing, but currently no cure exists. Rehabilitation focuses on maximizing function with the connections that remain.

❓ What is autonomic dysreflexia?

A life-threatening condition in injuries T6 and above. Noxious stimuli below injury (full bladder, pressure sore) cause sudden hypertension. Symptoms: pounding headache, sweating, hypertension. Emergency treatment required.

❓ Will I have normal bladder function?

Most SCI patients require bladder management — intermittent catheterization, indwelling catheters, or in some cases, reflex voiding. A urologist will help determine the safest approach for you.

❓ Can I have children?

Yes. Fertility in men is often reduced, but assisted reproduction techniques exist. Women typically retain fertility, though pregnancy requires high-risk management. Discuss with a specialist.
