Overview

How A Spinal Cord Injury Affects The Body

Quick Answer

A spinal cord injury is damage to the nerve bundle running through your spine, which carries messages between the brain and the rest of the body. It can weaken or stop movement, feeling and organ control below the injured point. It's an emergency, but fast care and rehab can protect remaining function.

Spinal cord injury: a broken or displaced vertebra presses into the cord, cutting off signals to the body below that level.

Think of the spinal cord as a cable of millions of nerve fibres, protected by the bones of your spine. When those bones break or shift, the cord can be bruised or squeezed, and far less often, torn. Oddly, pain isn't what tells doctors the most. Two things do: how high the injury sits, and whether any signals still get through. Together, they shape almost everything that follows.

A spinal cord injury most often follows a road accident or a sports-related injury in younger adults, or a fall in older ones, and the neck is the most commonly injured area. Not every spinal cord injury needs surgery, either. Some settle with bracing, close monitoring and rehabilitation alone.

Severity

Complete vs Incomplete Spinal Cord Injury

Doctors describe every spinal cord injury in two ways. Spinal cord injury levels name where along the spine it happened. The ASIA scale grades how complete it is, and your report will name one grade.

Complete (AIS A)

No movement or feeling remains below the injury, including in the lowest spinal nerves that serve the bladder, bowel and the area around them.

Sensory Only (AIS B)

Some feeling survives below the injury, down to the lowest part of the spine, but the muscles there can't be moved on purpose.

Some Movement (AIS C)

Some muscles below the injury still work, but most of them are too weak to lift a limb fully against gravity.

Useful Movement (AIS D)

At least half the key muscles below the injury can move against gravity, and walking again is often a realistic goal with rehab.

Symptoms

Signs of a Spinal Cord Injury to Recognise

  • MUSCLE WEAKNESS

    Arms, legs or both can feel weak, heavy or impossible to move. How much of the body is affected depends on where along the spine the damage sits.

  • NUMBNESS OR TINGLING

    Pins and needles, burning, or a complete loss of feeling below the injury are common. Some people can't sense touch, heat or cold on parts of their skin.

  • BLADDER AND BOWEL

    The nerves that control the bladder and bowel run through the lowest part of the cord, so leaking, or being unable to pass urine at all, can follow an injury.

  • BREATHING DIFFICULTY

    Injuries high in the neck can weaken the muscles used for breathing and coughing. Shallow breaths or a weak cough after a neck injury need urgent attention.

  • PAIN AND SPASMS

    Burning nerve pain, and muscle spasms that jerk the legs without warning, often appear in the weeks and months after the injury as the nervous system adjusts.

When To Worry

A Suspected Spinal Cord Injury Is Always An Emergency

Don't wait and see. If you suspect a spinal cord injury, call emergency services straight away and don't move the person unless they're in immediate danger, such as a fire. Moving an unstable neck or back can turn a partial injury into a permanent one.

Call For Emergency Help If You Notice:

Causes

Spinal Cord Injury Causes

  1. 01

    Road Traffic Accidents

    Car, bike and two-wheeler crashes are among the leading causes worldwide, often injuring the neck through sudden, violent impact, especially without a helmet or seatbelt.

  2. 02

    Falls

    Falls from a height, such as a roof, ladder or tree, and even simple falls in older adults with fragile bones can fracture vertebrae and injure the cord.

  3. 03

    Sports and Diving

    Diving into shallow water is a classic cause of neck injury in young people, alongside contact sports and falls from horses or bicycles at speed.

  4. 04

    Non-Traumatic Causes

    Not every injury comes from an accident. Tumours, infections such as spinal tuberculosis, and severe spinal arthritis can slowly squeeze the cord over months or years. Spinal Tuberculosis →

Who's More Likely To Have A Spinal Cord Injury

  • YOUNG ADULT MEN

    Men are injured far more often than women, with risk highest in their twenties.

  • OLDER ADULTS

    People over 65 can injure the cord in a minor fall, especially with osteoporosis or a spinal canal already narrowed by arthritis. Spondylosis & Spondylitis →

  • RISKY ACTIVITIES

    Riding without a seatbelt, diving into water of unknown depth and working at height without a harness all raise the risk considerably.

  • EXISTING SPINE DISEASE

    Spinal tumours, bone infections and severe arthritis weaken the spine, so a smaller force can cause damage a healthy spine would withstand.

Diagnosis

How Spinal Cord Injury Is Diagnosed

  1. 01

    Emergency Assessment

    At the scene and in the emergency room, the spine is kept still while doctors check breathing, blood pressure, strength, feeling and reflexes to start working out the level of injury.

  2. 02

    CT And MRI

    A CT scan quickly shows broken or displaced bones in the spine. An MRI then shows the cord itself, along with any disc, blood clot or swelling pressing on it.

  3. 03

    ASIA Grading

    A detailed nerve exam, repeated over the first few days as early swelling settles, sets your ASIA grade and level. That tells you whether the injury is complete or incomplete.

Treatment

Treatment After A Spinal Cord Injury

Surgery isn't always part of the plan, and when it is, the aim is simple: take pressure off the cord and steady the spine. Care moves through three phases.

  • EMERGENCY CARE

    focuses on keeping the spine still, protecting breathing and holding blood pressure up so the cord gets enough oxygen.

  • SURGERY, IF NEEDED

    relieves pressure on the cord or stabilises a broken spine, usually within the first days, when scans show it will help.

  • REHABILITATION

    begins as soon as you're stable and continues for months, rebuilding strength, independence and daily skills with a dedicated therapy team.

Treatment Options After The Injury

  1. 01

    Spinal Immobilisation

    NON-SURGICAL

    A rigid collar, spine board or brace holds the injured section still, preventing further damage while scans are done and decisions are made.

  2. 02

    Decompression Surgery

    SURGICAL

    Removes the bone fragments, disc material or blood clot pressing on the cord, giving the surviving nerve fibres a better chance of recovering.

    See Spine Surgery →
  3. 03

    Stabilisation Surgery

    SURGICAL

    Screws and rods hold a fractured or unstable spine in place, often through small incisions, so you can sit up and start rehab sooner.

    See Spine Surgery →
  4. 04

    Rehabilitation Therapy

    NON-SURGICAL

    Physiotherapy, occupational therapy and bladder and bowel training help you regain as much function and independence as your injury allows.

Outlook

Can You Recover From A Spinal Cord Injury?

Often, yes, at least partly. Recovery depends mostly on three factors: whether the injury is complete or incomplete, how high it sits, and how early treatment started. People with incomplete injuries tend to regain more movement and feeling. Complete injuries usually bring lasting changes, and rehab helps you adapt to them with confidence.

  • 15 MILLION PEOPLE

    worldwide live with a spinal cord injury, and many work, travel and raise families with the right support.

  • MOST RECOVERY

    happens within the first 3 to 6 months, though smaller gains can continue for a year or more with steady rehab.

  • IF IGNORED

    a missed unstable fracture, or moving someone without supporting the neck, can turn a partial injury into permanent paralysis, so emergency care comes first.

Living With It

Before Your Appointment

Questions To Ask Your Doctor

  1. 01

    Is my injury complete or incomplete, and what's my ASIA grade?

  2. 02

    At what level is my spinal cord injured, and what does that affect?

  3. 03

    Is anything still pressing on my cord that surgery could relieve?

  4. 04

    How much recovery is realistic for me, and over what time frame?

  5. 05

    Which rehabilitation programme do you recommend, and when should it start?

Told Surgery Is Needed After An Injury?

A second opinion on your scans can confirm whether surgery will help before you or your family decide.
