Scoliosis is a musculoskeletal condition where the spine curves sideways into an “S” or “C” shape when viewed from behind. It most commonly develops during childhood or adolescence, particularly around growth spurts, although milder cases may not be detected until adulthood. The severity of scoliosis varies widely, with some individuals experiencing minimal physical impact and others developing more pronounced spinal deformity.
In addition to the sideways curve, the spine often rotates, which can lead to visible changes in posture such as uneven shoulders, hips, or rib prominence. Physiotherapy for scoliosis plays an important role in improving posture, strength, and function, as well as supporting long-term spinal health.
Key Facts
- Idiopathic scoliosis accounts for approximately 80% of scoliosis cases.
- Scoliosis most commonly develops during periods of rapid growth in childhood and adolescence.
Risk Factors
- Family history of scoliosis
- Rapid growth during adolescence
- Neuromuscular or connective tissue conditions
Symptoms
- Uneven shoulders or shoulder height
- One shoulder blade more prominent than the other
- Uneven hips or waist asymmetry
- Rib prominence on one side when bending forward
- Localised muscle aches or fatigue in the back
- Back pain, more common in adults with scoliosis
- Difficulty breathing
Aggravating Factors
- Prolonged sitting or standing
- Periods of rapid growth
- Physically demanding activities that increase spinal load
Causes
The cause of scoliosis is often unknown, and when this is the case, it is referred to as idiopathic scoliosis— accounting for 80% of cases. However, scoliosis can also be linked to certain medical conditions, including:
- Cerebral palsy: A neurological condition that affects muscle control, which can lead to uneven growth and development of the spine.
- Muscular dystrophy: A group of genetic disorders that weaken the muscles, leading to poor spine support and abnormal curvature.
- Marfan syndrome: A connective tissue disorder that can cause skeletal abnormalities, including scoliosis.
Scoliosis may also occur due to congenital defects in the spine, previous spinal surgeries, or traumatic injuries.
How Is It Diagnosed?
Diagnosis of scoliosis begins with a physical examination to assess posture and spinal symmetry. A commonly used screening tool is the Adam’s forward bend test, where the individual bends forward at the waist while the clinician observes for rib or spinal prominence.
Definitive diagnosis is confirmed using spinal X-rays, which allow measurement of the Cobb angle. The Cobb angle quantifies the degree of spinal curvature and is used to determine severity, guide treatment decisions, and monitor progression over time.
Investigations & Imaging
- X-ray
- Used to confirm scoliosis and measure the Cobb angle to determine severity and progression
Grading / Classification
- Mild
- Cobb angle of 10 to 20 degrees with minimal physical impact
- Moderate
- Cobb angle of 20 to 40 degrees where bracing and physiotherapy may be required
- Severe
- Cobb angle greater than 40 to 50 degrees with increased risk of progression and complications
Physiotherapy Management
Physiotherapy plays a significant role in managing scoliosis, particularly in mild to moderate cases. The aim of physiotherapy is to:
- Improve muscular endurance
- Increase coordination and control
- Correct posture and side shifts
One well-known physiotherapy approach is the Schroth method, which is a scoliosis-specific exercise regime designed to:
- Promote muscular symmetry
- Improve postural awareness
- Help with ease of breathing
- Optimise movement patterns and overall function
Several studies support the Schroth method, demonstrating improvements in back strength, respiratory function, and a reduction in the likelihood of needing surgical interventions.
Exercise
Scoliosis physiotherapy exercises are tailored to the individual’s curve pattern and functional presentation. Programs commonly include:
- Core strengthening exercises: To enhance the stability and support of the spine.
- Stretching routines: To improve flexibility and reduce muscle tension on the concave side of the curve.
- Breathing exercises: To improve lung function, especially in cases where the rib cage is compressed.
Activity Modification
Activity modification may be required during periods of pain or rapid growth. Physiotherapists provide guidance on managing training loads, maintaining regular movement, and avoiding prolonged asymmetrical postures.
Manual Therapy
Manual therapy may be used as an adjunct to exercise to address muscle tightness or joint stiffness associated with scoliosis. Techniques are used to improve comfort and support active rehabilitation rather than correct the structural curve.
Bracing & Taping
Physiotherapy bracing and taping in scoliosis is used to support spinal alignment, improve postural awareness, and complement active rehabilitation rather than replace exercise-based management. In adolescents with idiopathic scoliosis, rigid or semi-rigid spinal bracing is typically prescribed by a specialist, with physiotherapists playing a key role in brace education, fit optimisation, skin care advice, and integrating the brace into daily movement and exercise. Physiotherapists also help patients adapt scoliosis-specific exercises while braced to maintain strength, mobility, and breathing capacity. Taping techniques may be used as an adjunct in some cases to provide proprioceptive feedback, encourage postural correction, or assist with muscle activation around the trunk, particularly in milder curves or in adults where bracing is not indicated. Importantly, physiotherapy ensures that bracing is part of a broader scoliosis management plan focused on function, confidence, and long-term spinal health rather than passive correction alone.
Heat & Ice
Heat may be used to reduce muscle tension and discomfort associated with scoliosis-related muscle fatigue.
Education
Education is a key element of physiotherapy for scoliosis. Understanding the condition, expected progression, and the role of exercise and bracing empowers individuals and families to engage in long-term management.
Other
Breathing exercises may be included, particularly in thoracic scoliosis, to improve chest expansion and breathing efficiency.
Other Treatments
For moderate scoliosis (20–40 degrees), an orthopaedic specialist may recommend wearing a back brace. Braces help to stop the curve from worsening, particularly in children and adolescents who are still growing. The most common type of brace is the thoracolumbosacral orthosis (TLSO), which fits around the torso and must be worn for most of the day to be effective.
Surgery
Surgery is typically reserved for severe scoliosis (curves of 40–50 degrees or more) or for cases where the curve is rapidly progressing despite other treatments. The goal of surgery is to correct the spinal curvature and stabilise the spine. The most common surgical procedure is spinal fusion, where metal rods, screws, and bone grafts are used to fuse the curved part of the spine into a straighter position. While surgery can significantly reduce the curve, it is a major procedure and carries risks, so it is only recommended when absolutely necessary.
Prognosis & Return to Activity
The prognosis for scoliosis depends largely on the severity of the curve and the age at diagnosis. Children and adolescents diagnosed early and with mild curves tend to have better outcomes with less likelihood of curve progression. Regular monitoring is essential, especially during growth spurts when curves can worsen.
In adults, progression is less likely but may still occur, particularly if scoliosis was not treated during childhood or adolescence. With proper management, most people with scoliosis can lead normal, active lives. In severe cases, especially where the curve impacts respiratory function, more intensive interventions may be needed.
Complications
- Chronic back pain in adulthood
- Reduced respiratory function in severe thoracic curves
- Progressive spinal deformity if untreated
Preventing Recurrence
- Regular monitoring during growth spurts
- Maintain spinal strength and postural awareness
- Early physiotherapy intervention for asymmetry or pain
