Brown-Séquard syndrome is an uncommon incomplete spinal cord injury that can affect strength, sensation, balance and walking. Learn about its causes, symptoms, diagnosis, recovery and evidence-informed physiotherapy rehabilitation.

Brown-Séquard syndrome (BSS) is an uncommon neurological condition caused by damage affecting one side of the spinal cord. Because the spinal cord carries different types of movement, sensation and pain/temperature signals through different pathways, an injury to one side can produce a distinctive combination of neurological problems.

For patients and families, the condition can initially be confusing. Weakness may be more noticeable on one side, while loss of pain or temperature sensation may occur differently. Understanding these patterns can help patients recognize why rehabilitation is often an important part of recovery.

Physiotherapy does not repair a damaged spinal cord directly, but appropriately planned rehabilitation can help a person improve movement, balance, walking ability, functional independence and participation in everyday activities.

Important: Brown-Séquard syndrome requires medical and neurological assessment. New or rapidly worsening weakness, numbness, difficulty walking, bladder/bowel changes or other spinal cord symptoms should be assessed urgently.

What Is Brown-Séquard Syndrome?

Brown-Séquard syndrome is a partial spinal cord injury syndrome in which one side of the spinal cord is predominantly affected.

The spinal cord contains several pathways responsible for:

• Voluntary movement
• Position and vibration sensation
• Pain and temperature sensation
• Coordination of information between the brain and body

When one side of the spinal cord is damaged, these pathways can be affected in different ways. This produces a characteristic neurological pattern.

Brown-Séquard syndrome is sometimes described as spinal cord hemisection syndrome, although a complete anatomical hemisection is not present in every patient.

Why does one spinal cord injury cause different symptoms?

The key is that different nerve pathways travel through the spinal cord differently.

For example:

• Some motor pathways have already crossed before reaching the spinal cord.
• The pathway carrying vibration and position information crosses higher up, in the brainstem.
• Pain and temperature pathways generally cross within the spinal cord, often within a few spinal segments of entering it.

Therefore, damage to one side of the spinal cord can affect movement and certain sensations on the same side while affecting pain and temperature sensation on the opposite side.

Brown-Séquard Syndrome Symptoms

Symptoms depend on the level, severity and cause of spinal cord involvement.

A classic pattern may include:

1. Weakness on the affected side

Damage to descending motor pathways can cause weakness or paralysis on the same side of the body below the level of the spinal cord lesion.

Patients may experience:

• Difficulty standing
• Reduced leg strength
• Difficulty walking
• Poor foot control
• Reduced hand function when the cervical spinal cord is involved
• Reduced ability to perform daily activities

The severity varies considerably from one patient to another.

2. Loss of vibration and position sense

The affected side may have impaired:

• Joint-position sense
• Vibration sensation
• Fine touch discrimination

This can make walking and balance more difficult because the brain receives less accurate information about where the limbs are positioned.

3. Loss of pain and temperature sensation

Pain and temperature sensation may be reduced on the opposite side of the body, usually beginning several spinal segments below the lesion.

This is one of the features that can make Brown-Séquard syndrome clinically distinctive.

4. Changes in reflexes

Reflex findings can vary depending on:

• The level of the spinal cord injury
• Whether the lesion is acute or chronic
• Which neurological pathways are involved

An acute spinal cord lesion may initially produce different findings from those seen later during recovery.

5. Changes in muscle tone

Some patients may develop increased muscle tone or spasticity below the level of the lesion.

Spasticity may contribute to:

• Stiff movements
• Difficulty bending or straightening joints
• Abnormal walking patterns
• Muscle spasms
• Reduced functional movement

However, not every person with Brown-Séquard syndrome develops significant spasticity.

Causes of Brown-Séquard Syndrome

Brown-Séquard syndrome can occur due to different conditions that damage one side of the spinal cord.

Common causes include:

• Traumatic spinal cord injury
• Penetrating spinal injuries
• Spinal fractures or dislocations
• Spinal tumors
• Cervical or thoracic spinal cord compression
• Inflammatory conditions
• Multiple sclerosis
• Infections
• Vascular problems affecting the spinal cord
• Less commonly, other structural or neurological disorders

The cause is important because treatment and prognosis depend not only on the neurological pattern but also on the underlying condition.

Brown-Séquard Syndrome and Spinal Cord Level

The location of the spinal cord lesion strongly influences symptoms.

Cervical spinal cord involvement

A lesion in the neck region can affect:

• Arms
• Hands
• Trunk
• Legs
• Walking
• Balance

Higher cervical involvement can potentially affect more extensive motor and sensory functions.

Thoracic spinal cord involvement

Thoracic lesions may primarily affect:

• Trunk control
• Lower-limb strength
• Lower-limb sensation
• Standing and walking

Lumbar or lower spinal cord involvement

The clinical presentation can differ substantially because the anatomy of the spinal cord changes toward its lower end.

For this reason, a neurological examination is essential rather than assuming that every Brown-Séquard syndrome patient will have the same symptoms.

How Is Brown-Séquard Syndrome Diagnosed?

Diagnosis involves combining the patient’s history with a detailed neurological examination and appropriate investigations.

A doctor may assess:

• Muscle strength
• Muscle tone
• Deep tendon reflexes
• Superficial sensation
• Pain and temperature sensation
• Vibration
• Proprioception
• Coordination
• Balance
• Walking ability
• Bladder and bowel function
• Level of the spinal cord affected

Imaging

MRI of the spine is particularly important for evaluating the spinal cord and identifying conditions such as:

• Spinal cord compression
• Edema
• Hemorrhage
• Tumors
• Inflammatory lesions
• Other structural abnormalities

CT or other investigations may also be appropriate depending on the suspected cause, particularly after trauma.

Brown-Séquard Syndrome vs Complete Spinal Cord Injury

Brown-Séquard syndrome is generally considered an incomplete spinal cord injury.

This means that some neurological pathways remain intact.

In an incomplete spinal cord injury, a person may retain varying degrees of:

• Motor function
• Sensation
• Voluntary movement
• Trunk control
• Walking potential

The amount of preserved function differs significantly between individuals.

This is why rehabilitation should be based on the person’s actual neurological and functional presentation rather than the diagnosis alone.

Physiotherapy Management of Brown-Séquard Syndrome

Physiotherapy is an important component of multidisciplinary rehabilitation for many people with Brown-Séquard syndrome.

The treatment plan should be individualized after neurological and musculoskeletal assessment.

The primary goals may include:

• Maintaining joint mobility
• Preventing secondary complications
• Improving muscle strength
• Improving postural control
• Developing balance
• Improving walking
• Increasing functional independence
• Improving cardiovascular fitness
• Training safe transfers
• Improving participation in daily activities

1. Initial Physiotherapy Assessment

A physiotherapist may assess:

Motor function

• Manual muscle testing
• Functional movement
• Selective motor control
• Lower- and upper-limb strength

Sensory function

• Light touch
• Pain and temperature awareness
• Proprioception
• Vibration where appropriate

Tone and reflexes

Assessment for:

• Spasticity
• Hypotonia
• Abnormal reflex activity
• Clonus

Functional mobility

The physiotherapist may evaluate:

• Rolling
• Sitting
• Sit-to-stand
• Transfers
• Standing
• Walking
• Stair negotiation
• Bed mobility

Balance

Both static and dynamic balance should be assessed.

This is especially important when proprioception or lower-limb sensory information is impaired.

Exercise Therapy for Brown-Séquard Syndrome

Exercise selection should depend on the person’s neurological status, medical stability and functional goals.

1. Active and active-assisted exercises

These can help maintain movement and encourage motor control.

Examples may include:

• Hip flexion and extension
• Knee flexion and extension
• Ankle movements
• Shoulder movements
• Elbow flexion and extension
• Wrist and hand exercises

The exercises should be performed within safe ranges and adjusted according to strength and control.

2. Strengthening exercises

Progressive strengthening can be considered when adequate movement is available.

Examples include:

• Sit-to-stand practice
• Supported squats
• Resistance-band exercises
• Step-ups
• Bridging
• Hip strengthening
• Knee strengthening
• Ankle strengthening

Resistance and repetitions should be progressed gradually.

3. Balance training

Balance rehabilitation may include:

• Sitting balance
• Weight shifting
• Supported standing
• Reaching activities
• Standing with reduced upper-limb support
• Controlled stepping
• Dynamic balance activities

If proprioception is impaired, visual information may become particularly important during certain tasks.

4. Gait training

Walking rehabilitation may involve:

• Parallel-bar walking
• Weight-shifting practice
• Step training
• Assistive-device training
• Treadmill-based gait training when appropriate
• Overground walking
• Stair training

An appropriate walking aid may improve safety and independence.

The device should be selected after individual assessment rather than simply choosing one based on diagnosis.

Neurorehabilitation Techniques

Depending on the patient’s presentation, physiotherapy may incorporate principles from neurological rehabilitation such as:

• Task-specific training
• Repetitive movement practice
• Motor relearning
• Balance and postural training
• Functional strengthening
• Gait re-education
• Proprioceptive training
• Coordination exercises
• Facilitation techniques where clinically appropriate

The emphasis should be on meaningful, goal-directed practice rather than performing exercises without a functional purpose.

Management of Spasticity and Muscle Tightness

Some people with Brown-Séquard syndrome develop increased muscle tone.

Physiotherapy may include:

• Slow controlled movements
• Active range-of-motion exercises
• Positioning
• Functional weight-bearing
• Stretching when appropriate
• Strength and motor-control training
• Gait training
• Education about triggers that worsen symptoms

Persistent or severe spasticity may require medical management in addition to physiotherapy.

A sudden increase in spasticity should not automatically be treated by simply stretching harder. Possible triggers such as pain, infection, skin problems, bladder issues or other medical complications may need evaluation.

Physiotherapy for Walking Difficulties

Walking problems can result from a combination of:

• Muscle weakness
• Reduced proprioception
• Poor balance
• Altered muscle tone
• Reduced motor control
• Sensory loss
• Joint stiffness
• Reduced endurance

Therefore, gait rehabilitation should address the cause of the walking limitation, not just the walking pattern.

A physiotherapist may work on:

1. Trunk control
2. Standing alignment
3. Weight transfer
4. Foot placement
5. Step length
6. Knee control
7. Hip control
8. Ankle control
9. Balance
10. Walking endurance

Occupational and Functional Rehabilitation

Physiotherapy is only one part of rehabilitation.

Depending on the patient’s needs, a multidisciplinary team may include:

• Neurologist
• Neurosurgeon or spine specialist
• Physiotherapist
• Occupational therapist
• Rehabilitation physician
• Speech and language therapist when indicated
• Psychologist or counsellor when appropriate
• Nursing professionals

Occupational therapy can be particularly helpful for improving independence in activities such as dressing, bathing, feeding and household tasks.

Home Physiotherapy Advice for Brown-Séquard Syndrome

A structured home program can complement supervised rehabilitation.

Useful principles include:

• Perform prescribed exercises regularly.
• Practice safe transfers rather than attempting difficult movements without assistance.
• Use prescribed walking aids correctly.
• Keep frequently used household objects within safe reach.
• Remove loose rugs and other fall hazards.
• Wear appropriate footwear.
• Avoid walking alone if balance is significantly impaired.
• Inspect areas with reduced sensation regularly for injuries or pressure-related skin problems.
• Follow the medical team’s recommendations regarding spinal precautions.

Do not push through significant neurological symptoms

Exercise should not cause new or progressively worsening:

• Weakness
• Numbness
• Severe pain
• Dizziness
• Loss of balance
• Bladder or bowel changes

Such symptoms warrant medical assessment.

Precautions During Physiotherapy

Brown-Séquard syndrome requires careful rehabilitation planning.

Important precautions include:

• Follow spinal precautions when prescribed.
• Avoid aggressive spinal manipulation unless specifically medically indicated and appropriately cleared.
• Monitor fatigue during exercise.
• Protect areas with reduced sensation from heat and pressure injuries.
• Use appropriate support during standing and gait training.
• Progress exercise gradually.
• Monitor skin condition in patients with reduced mobility.
• Consider fall risk before balance or walking exercises.
• Coordinate rehabilitation with the treating medical team when significant neurological changes occur.

Heat-based modalities require particular caution when pain or temperature sensation is impaired because the patient may not adequately detect excessive heat.

Can Brown-Séquard Syndrome Improve?

Recovery varies considerably.

The outcome depends on factors such as:

• Cause of the spinal cord injury
• Level of injury
• Severity of neurological damage
• Completeness of the injury
• Time since injury
• Age and general health
• Presence of complications
• Early and appropriate rehabilitation
• Individual response to treatment

Some patients experience meaningful improvements in strength, sensation and walking ability, while others may have persistent neurological impairments.

It is therefore inappropriate to promise a specific recovery time or guaranteed cure.

Why rehabilitation matters

The nervous system has the capacity for adaptation and functional reorganization after injury. Rehabilitation takes advantage of this by providing repeated, appropriately challenging and meaningful practice.

Progress may be gradual, and functional improvements can occur in different areas at different rates.

When Should You Seek Urgent Medical Attention?

A person with spinal cord symptoms should seek urgent medical evaluation if they develop:

• Sudden or rapidly worsening weakness
• New loss of sensation
• New difficulty walking
• Severe spinal pain after trauma
• Loss of bladder or bowel control
• New urinary retention
• Rapidly increasing muscle spasms
• Breathing difficulties
• New neurological symptoms

These symptoms can indicate a potentially serious spinal or neurological problem.
