Paraplegia: Understanding a Life-Changing Injury

Paraplegia: What It Means, Causes, and What Families Can Do

Did a doctor just use the word paraplegia about you or someone you love? If so, your family’s world has probably shifted. You may be sitting in a hospital hallway. You may be trying to picture the next months and years.

This page is written for that moment. Plain language first. Plus answers to the questions people really ask.

Paraplegia is paralysis of the lower half of the body. It usually affects the legs. It often affects part of the trunk too. The arms and hands keep working. It most often follows damage to the spinal cord in the mid or lower back.

This is general education. It is not medical or legal advice. But it will help you understand what the word means and what caused it. Near the end, we explain your options if someone else’s carelessness caused this.

What paraplegia actually means

Paraplegia describes what is affected. It is not a single disease. Two people with the same diagnosis can move and feel very differently. The word comes from Greek roots meaning “beside.” It points to both legs being involved.

Doctors describe each injury in two ways:

• Complete or incomplete. In a complete injury, there is no movement or feeling below the injury. In an incomplete injury, some signals still get through.
• Level. This is where on the spine the damage sits.

Medical teams grade this with the ASIA Impairment Scale. It is a standard A-through-E system kept by the American Spinal Injury Association. Have you seen “AIS A” or “T10 ASIA B” in a chart? That is what those letters mean.

This page sits inside our injury glossary. So you can jump between related terms as questions come up — paralysis, tetraplegia, and cauda equina syndrome.

Why the spinal cord causes it

The spinal cord is a bundle of nerves. It carries messages between the brain and the body. When it is damaged, signals stop below the injury.

The level of the injury matters a lot:

• Damage to the thoracic, lumbar, or sacral spine (mid-back down) usually causes paraplegia. The arms are spared.
• Damage higher up, in the cervical (neck) region, affects the arms too. This causes quadriplegia.

The Mayo Clinic notes something important. The higher the injury on the spine, the more function tends to be lost.

What causes traumatic paraplegia

Most cases our attorneys see follow a sudden event. Common causes include:

• Truck and car crashes. In a heavy-truck crash, the force can break the spine or drive bone into the cord.
• Serious falls. These happen from height at a worksite, or on unsafe property.
• Violence. This includes gunshot wounds and assaults.
• Diving and sports incidents.

There are also non-traumatic causes. These are tumors, infections, and diseases that damage the cord over time. Hereditary spastic paraplegia is a genetic condition. It develops slowly, not from a single event. These are different from the sudden, trauma-based paraplegia our firm focuses on.

The line comes down to timing and cause. Traumatic paraplegia happens in an instant. When that instant traces back to someone else’s carelessness, families have legal questions. We address those below.

How paraplegia affects the body

The loss of movement and feeling in the legs is the most visible effect. But the secondary changes often catch families off guard. The Mayo Clinic says these can include:

• Changes in bladder and bowel control
• Spasticity (muscle tightness) or spasms
• A higher risk of pressure sores from sitting or lying in one position
• Changes in sexual function, and sometimes in blood pressure control

How much a person is affected comes back to those two factors. First, complete versus incomplete. Second, how high on the spine the injury sits. Every person is different. A care team looks at each case on its own.

Can someone with paraplegia walk again?

It depends on the injury. No one can promise an answer in advance.

Some people with incomplete injuries regain limited movement. Braces, leg supports, and rehab help some people stand or take steps. Powered exoskeletons (robotic support suits) are used in some rehab programs. They are still being studied. Many people with paraplegia use wheelchairs and adaptive equipment to live on their own.

We will not promise any specific recovery. No one honestly can. What movement returns — if any — is a medical question. A person’s own doctors and therapists answer it over time.

Paraplegia vs. quadriplegia (tetraplegia)

Paraplegia affects the lower body. Quadriplegia affects all four limbs — both arms and both legs. The difference is where the cord is injured. Quadriplegia usually comes from a neck (cervical) injury. That is high enough to cut off signals to the arms as well as the legs.

The Mayo Clinic confirms this. Paralysis of both arms and legs is called quadriplegia or tetraplegia. The two words mean the same thing. Learn more in our tetraplegia glossary entry.

The four types of paralysis

Paralysis is grouped into four types. The groups are based on which body parts are affected:

• Monoplegia — one limb (a single arm or leg)
• Hemiplegia — one side of the body (the arm and leg on the same side)
• Paraplegia — the lower body, usually both legs
• Quadriplegia (tetraplegia) — all four limbs

Paraplegia vs. hemiplegia: Hemiplegia affects one side — for example, the right arm and right leg together. It often follows a brain injury or stroke, not a spinal cord injury.

Paraplegia vs. diplegia: Diplegia affects the same area on both sides, such as both legs. It is often linked to a brain cause like cerebral palsy. See our paralysis glossary entry for the full overview.

Treatment and long-term management

Care usually starts with emergency treatment to stabilize the spine. Then comes rehab. Rehab focuses on independence and preventing complications. There is no current treatment that reverses a spinal cord injury.

Rehab often combines:

• Physical therapy to build strength and function
• Occupational therapy to relearn daily tasks
• Assistive devices — wheelchairs, braces, and home or vehicle changes
• Ongoing medical care for spasticity, bladder health, and skin protection

Researchers keep studying spinal-cord regeneration. But it is not yet something patients can rely on. We say that plainly, so no one is misled by hopeful headlines.

Here is what is clear. Paraplegia often needs lifelong care, and that care is expensive. The Christopher & Dana Reeve Foundation’s cost-of-living resources show how costs add up over a lifetime. That reality matters directly when someone else caused the injury.

Related terms in our glossary

Are you researching paraplegia? These related entries help fill in the picture:

• Cauda equina syndrome — pressure on the nerves at the base of the cord. It is a medical emergency. It can cause lower-body paralysis and bladder problems.
• Paralysis — the parent term, and how the four types differ
• Tetraplegia (quadriplegia) — when all four limbs are involved

When someone else caused the injury

Sometimes paraplegia isn’t just bad luck. Picture a few situations:

• A truck ran a light and crushed the driver’s side of a car.
• Someone was shot or attacked in an apartment complex parking lot. The gate had been broken for months. The lights were out. There were no cameras and no security on duty.
• A worker fell because a property was left in a dangerous state.

Look at that second situation. A person is assaulted, robbed, or shot on someone else’s property. That could be an apartment complex, a parking garage, a hotel, a store, a bar, or a gas station. The owner failed to provide reasonable security. That means working locks and gates, lighting, cameras, or guards. In that case, the property owner may share the blame for the harm.

Lawyers call this a negligent security claim. You don’t need to know that term to ask whether you have a case.

Catastrophic-injury claims often center on the huge costs of a permanent injury. These include future medical care, lost income, home and vehicle changes, and the human toll on the whole family. Two Florida rules matter early on:

• Deadlines. Many negligence claims must be filed within two years under Fla. Stat. §95.11. A 2023 change in Florida law shortened this deadline from four years. Waiting can cost you the claim entirely.
• Shared fault. Under Fla. Stat. §768.81, someone found more than 50% at fault generally recovers nothing.
