Scoliosis

Physiotherapist assessing shoulder rib-cage and pelvic symmetry for scoliosis

A physiotherapist checks shoulder, rib-cage and pelvic symmetry during a scoliosis assessment.

Quick Answer

Scoliosis is a sideways curvature and rotation of the spine. It often develops during adolescence, although adults can also develop or live with scoliosis. Many curves remain mild and cause few problems. Others may progress, affect posture or contribute to muscle fatigue, back discomfort and reduced activity tolerance.

Physiotherapy may help manage pain, movement, strength, breathing mechanics and physical function. However, exercise does not reliably straighten every structural curve. Children and teenagers with a suspected or changing curve may also need medical imaging, growth monitoring, bracing advice or orthopaedic review.

Scoliosis physiotherapy focuses on how a spinal curve affects posture, movement, muscle control, comfort and daily activity. Treatment should match the person rather than using one standard exercise programme for every curve.

Scoliosis can affect the thoracic spine, lumbar spine or both regions. The vertebrae may also rotate, which can change the position of the ribs, shoulders, waist or pelvis. Explore our broader spinal conditions information for other causes of back and spinal symptoms.

What Is Scoliosis?

Scoliosis describes an abnormal sideways spinal curve when viewed from the front or back. A structural scoliosis usually also includes some vertebral rotation. This three-dimensional change may create a visible rib prominence, uneven shoulders, a shifted waist or uneven hips.

Doctors generally confirm scoliosis using a standing spinal X-ray. They measure the curve with the Cobb angle. A curve greater than 10 degrees generally meets the radiographic definition of scoliosis.

The Cobb angle is important, but it is not the only treatment factor. Age, remaining growth, curve location, curve progression, symptoms, physical function and overall health also guide management.

Scoliosis Is More Than Poor Posture

A structural scoliosis does not occur simply because someone sits badly, carries a schoolbag on one shoulder or has weak posture muscles. Posture may affect comfort and appearance, but it does not explain most adolescent idiopathic scoliosis.

What Are the Main Types of Scoliosis?

Idiopathic scoliosis

Idiopathic means there is no single known cause. Adolescent idiopathic scoliosis is the most common form diagnosed during the teenage growth period.

Congenital or neuromuscular scoliosis

Some curves relate to vertebral development, neurological conditions, muscle disorders or other health conditions. These presentations require coordinated medical care.

Adult or degenerative scoliosis

Adults may have a curve that began earlier in life or develop a curve through age-related spinal and joint changes. Pain, stiffness and walking tolerance may become more relevant.

What Is a Non-Structural or Compensatory Curve?

A non-structural curve may appear because of positioning, pain-related guarding, pelvic asymmetry or a leg-length difference. It may reduce when the contributing factor or position changes. A clinician should assess the cause rather than assuming that a visible asymmetry is either structural or harmless.

What Causes Scoliosis?

Most adolescent scoliosis is idiopathic, which means no single cause can be identified. Current evidence suggests that growth, genetics and several biological and mechanical factors may contribute. It is not usually caused by everyday posture, sport or normal physical activity.

Other scoliosis types may relate to:

differences in vertebral development present from birth
neurological or muscular conditions
connective tissue or genetic conditions
age-related spinal joint and disc changes
previous spinal surgery, injury or disease
a compensatory response to another musculoskeletal problem

What Are the Signs of Scoliosis?

Scoliosis does not always cause pain. A parent, teacher, coach or clinician may first notice a change in body symmetry.

Common posture signs

one shoulder sitting higher than the other
one shoulder blade appearing more prominent
uneven waist creases or hip height
the body leaning or shifting to one side
the head appearing off-centre over the pelvis
one side of the rib cage becoming more prominent during forward bending

Possible physical symptoms

back muscle fatigue or tightness
aching after prolonged sitting or standing
reduced spinal or rib-cage mobility
difficulty maintaining one position
reduced tolerance for walking, work or exercise
concerns about body shape or confidence

How Does Scoliosis Affect Children and Teenagers?

For children and teenagers, the main concern is whether the curve may progress during growth. Progression risk varies. It generally depends on remaining skeletal growth, curve size, curve pattern and whether measurements change over time.

Many young people with scoliosis can continue school, sport and normal physical activity. A clinician may modify exercises when pain, fatigue, balance, breathing mechanics or movement control limit participation.

Arrange an Assessment During Growth If You Notice:

a new or increasing rib prominence
rapidly changing shoulder, waist or hip symmetry
a visible curve that appears to be progressing
ongoing pain that limits school, sleep, sport or activity
weakness, altered sensation, poor balance or changes in walking

Our guide to back pain in teenagers explains other reasons a young person may develop back symptoms.

How Does Scoliosis Affect Adults?

Adults may have adolescent scoliosis that has continued into later life, or they may develop degenerative scoliosis as spinal discs and joints change with age. The curve itself does not always determine symptom severity.

Adult scoliosis symptoms may include:

local back pain or muscle fatigue
stiffness after sitting or standing
reduced walking or standing tolerance
leg pain, tingling or weakness where nerves are affected
difficulty with lifting, work, exercise or household tasks
changes in balance or confidence with movement

Management often focuses on pain, function, strength, mobility, activity tolerance and confidence rather than trying to make the spine appear perfectly straight.

Does Scoliosis Cause Back Pain?

Scoliosis may contribute to back discomfort, but it is not always the only cause. Some people with substantial curves have little pain, while others with smaller curves experience symptoms from muscle fatigue, joint sensitivity, reduced conditioning or another spinal condition.

A physiotherapy assessment considers the pain pattern, spinal movement, strength, nerve symptoms, daily loads and other possible sources. The broader back pain section may also help when pain is the main concern.

How Is Scoliosis Diagnosed?

A physiotherapist or doctor may begin by reviewing growth, symptoms, health history and any family history of scoliosis. The physical examination may include posture, spinal movement, rib-cage position, shoulder and pelvic symmetry, leg length, strength, balance and neurological testing.

Forward-Bend Assessment

During a forward-bend test, the clinician looks for trunk or rib-cage asymmetry. A scoliometer may help measure trunk rotation. This test can identify a pattern that needs further investigation, but it does not replace an X-ray diagnosis.

Standing Spinal X-Rays

When scoliosis is suspected, a doctor may request standing spinal X-rays. These images show the full curve under normal weight-bearing and allow the Cobb angle to be measured. Repeat imaging may be recommended when growth or progression needs monitoring.

When Are MRI or CT Scans Used?

MRI or CT is not required for every scoliosis presentation. A doctor may consider further imaging when neurological findings, unusual curve patterns, very young onset or another medical concern requires investigation.

Can Scoliosis Get Worse?

Some curves remain stable, while others progress. Growth is an important risk period for adolescent idiopathic scoliosis. Larger curves and curves identified earlier in skeletal development may require closer monitoring.

In adults, progression may relate to the original curve, age-related spinal changes and overall spinal balance. Regular review is not necessary for every adult, but reassessment may help when posture changes, symptoms increase or function declines.

How Is Scoliosis Treated?

Treatment depends on the type of scoliosis, age, growth, curve size, progression, symptoms and personal goals. Management may include observation, physiotherapy, scoliosis-specific exercise, bracing, medical review or surgery.

Monitoring

Mild curves may only need periodic clinical or imaging review, particularly while a young person is growing.

Exercise and physiotherapy

A tailored programme may address spinal control, breathing, mobility, strength, endurance, pain and activity goals.

Specialist treatment

Bracing or surgery may be considered when progression risk, curve severity, health or function warrants specialist care.

Can Physiotherapy Help Scoliosis?

Physiotherapy cannot promise to straighten a structural scoliosis. However, it may help a person understand their curve, manage symptoms and build the physical capacity needed for everyday life, work and sport.

A scoliosis physiotherapy programme may include:

education about the individual curve and symptom pattern
scoliosis-specific or active self-correction exercises where appropriate
breathing exercises and rib-cage expansion strategies
trunk, hip and shoulder-girdle strengthening
spinal and lower-limb mobility work
balance and movement-control exercises
graded walking, gym, work or sport conditioning
strategies for sitting, standing, lifting and load management
pain-management strategies for adult scoliosis
rehabilitation before or after spinal surgery where required

Exercise selection should reflect the curve pattern, symptoms, age, health and goals. A structured exercise programme can then progress as control, strength and activity tolerance improve.

What Are Scoliosis-Specific Exercises?

Scoliosis-specific exercise uses the person’s individual curve pattern to guide posture, active correction, breathing and movement practice. Several recognised approaches exist. The clinician should select and teach exercises carefully rather than giving a generic list from the internet.

Research suggests these programmes may improve some measures of posture, function and quality of life in adolescents. However, results vary, and exercise should not delay medical monitoring or bracing when those treatments are recommended.

Do General Strength Exercises Help?

General strength and aerobic exercise may improve fitness, muscle endurance, bone health and confidence. These benefits matter even when the spinal curve itself does not change. Exercise should remain comfortable and progressive, with modifications where pain, fatigue or another health condition affects tolerance.

When Is Bracing Considered?

Bracing is mainly used for selected children and adolescents who still have skeletal growth remaining and have a meaningful risk of curve progression. The aim is usually to reduce progression risk rather than permanently force the spine into a perfectly straight position.

An orthopaedic or spinal specialist determines whether bracing is appropriate. The decision considers the Cobb angle, remaining growth, curve pattern, progression and individual circumstances. Brace fit, wearing time and follow-up all influence the result.

Physiotherapy may support comfort, strength, breathing, exercise participation and movement while a brace is being used. It does not replace specialist brace management.

When Is Scoliosis Surgery Considered?

Surgery may be considered for severe or progressing curves, significant imbalance, neurological compromise, breathing concerns or substantial effects on health and function. The recommendation depends on much more than one number.

Before surgery, physiotherapy may help maintain strength, fitness and confidence. After surgery, rehabilitation follows the surgeon’s restrictions and may gradually address walking, mobility, strength, daily tasks, school, work and return to exercise.

Can You Exercise and Play Sport With Scoliosis?

Most people with scoliosis can remain physically active. Walking, swimming, cycling, gym exercise, running and team sport may all be suitable, depending on symptoms, medical advice and treatment stage.

Sport does not usually need to stop simply because scoliosis has been diagnosed. A physiotherapist may help modify training when pain, fatigue, brace use, surgery or another health condition changes what is currently safe or comfortable.

Focus on Function, Not Perfect Symmetry

A useful rehabilitation plan aims to improve comfort, movement, strength, confidence and participation. Small posture differences do not automatically mean that activity is unsafe or that treatment has failed.

What Can You Do at Home?

Home management should support, rather than replace, appropriate assessment and monitoring.

Follow the exercises prescribed for your curve and symptoms.
Stay active through comfortable walking, sport or general exercise.
Change position regularly during long periods of sitting or standing.
Build strength progressively rather than suddenly increasing load.
Use school, work or lifting modifications only when they make activity easier.
Track meaningful changes in pain, posture, walking tolerance or nerve symptoms.
Attend recommended medical, imaging, brace or orthopaedic reviews.

General posture strategies may improve comfort, but they should not be presented as a cure for structural scoliosis.

When Should You Seek Medical Advice?

Seek Prompt Medical Assessment If Scoliosis Is Associated With:

new or progressive limb weakness
loss of sensation or worsening pins and needles
changes in walking, coordination or balance
new bowel or bladder control changes
numbness around the groin or saddle region
significant breathing difficulty
severe, constant or rapidly worsening pain
fever, unexplained weight loss or significant illness
a rapidly changing curve or asymmetry during growth
an unusual curve identified in a very young child

Call emergency services for severe neurological symptoms, major breathing difficulty or sudden symptoms that may represent a medical emergency.

What Happens During a Physiotherapy Assessment?

Your physiotherapist will ask about symptoms, growth or diagnosis history, imaging, medical management, activity, work or school demands and personal goals. The physical assessment may include posture, spinal movement, rib-cage mobility, strength, balance, walking and relevant neurological tests.

From there, the physiotherapist can explain which findings may respond to rehabilitation and whether medical, imaging, orthopaedic or other specialist input is needed. A broader musculoskeletal physiotherapy approach may help when scoliosis overlaps with back pain, reduced conditioning or another joint or muscle problem.

Scoliosis FAQs

What is scoliosis?

Scoliosis is an abnormal sideways curvature and rotation of the spine. It may affect the thoracic spine, lumbar spine or both. Doctors generally confirm scoliosis on a standing spinal X-ray using the Cobb angle.

Is scoliosis caused by poor posture?

Most structural scoliosis is not caused by poor sitting posture, carrying a schoolbag or weak posture muscles. Posture may affect comfort and appearance, but it does not explain most adolescent idiopathic scoliosis.

Can physiotherapy help scoliosis?

Physiotherapy may help improve spinal control, strength, breathing mechanics, mobility, comfort and physical function. It may also support sport, work and daily activity. Physiotherapy does not replace medical monitoring, bracing or surgery when those treatments are indicated.

Can exercises straighten scoliosis?

Exercises do not reliably straighten every structural scoliosis curve. Scoliosis-specific exercise may improve posture control, function, quality of life and some clinical measurements for selected people. Results depend on the curve, age, growth, adherence and treatment plan.

Does scoliosis always cause back pain?

No. Many people with scoliosis have little or no pain. Others experience muscle fatigue, aching, stiffness or reduced tolerance for prolonged activity. Assessment can help determine whether symptoms relate to the curve or another spinal problem.

Can a child with scoliosis continue playing sport?

Most children and teenagers with scoliosis can remain active and play sport. Medical advice may change during bracing, after surgery or when neurological, respiratory or other health concerns are present.

When should scoliosis be reviewed?

Arrange a review when visible asymmetry appears, a known curve seems to change, pain persists or symptoms affect school, sleep, work, walking or sport. Children and teenagers may need closer monitoring while they are growing.

What to Do Next

Book a physiotherapy assessment if scoliosis is affecting comfort, movement, exercise, work or confidence. A physiotherapist can assess function, explain which findings may respond to rehabilitation and help identify when medical or orthopaedic review is appropriate.

For a child or teenager with a new or changing spinal curve, arrange a medical assessment rather than relying on exercise alone.
