Scoliosis
What Is Scoliosis?
Scoliosis is a spinal condition characterized by a sideways curvature of the spine measuring more than 10 degrees when viewed from behind. While a healthy spine appears straight, scoliosis causes it to curve either to the right or left, often forming an “S” or “C” shape.
However, scoliosis is more than a simple lateral bend—it’s a complex, three-dimensional structural deformity that may also involve spinal rotation and changes in posture when viewed from the side or front. Scoliosis can affect people of all ages, from children to adults, and varies widely in severity.

What Are the Symptoms of Scoliosis?
Scoliosis is often painless in its early stages, especially in children, which makes early detection critical. Parents or caregivers often notice physical asymmetries before a diagnosis is made. Common signs and symptoms include:
- Uneven shoulders (one higher than the other)
- One shoulder blade more prominent than the other
- Asymmetry in the waist or hips
- A visible curve in the spine when bending forward
- One side of the rib cage appearing higher
- Back pain or lower back discomfort in adults
- Fatigue or shortness of breath (in advanced cases)
- In adolescents, scoliosis may worsen rapidly during growth spurts
Although the condition progresses in only about 10% of cases, more severe curves may require surgical intervention.

What Causes Scoliosis?
- Idiopathic Scoliosis – Most common, with no known cause (typically appears in adolescence)
- Congenital Scoliosis – Caused by vertebral malformations present at birth
- Neuromuscular Scoliosis – Associated with conditions like cerebral palsy or muscular dystrophy
- Degenerative Scoliosis – Often occurs in adults due to age-related disc degeneration
Scoliosis Strength & Physical Therapy Exercises
A cornerstone of non-surgical scoliosis treatment, physical therapy aims to:
- Improve posture and spinal alignment
- Strengthen muscles supporting the spine
- Reduce discomfort and fatigue
- Slow or stop curve progression
Physical therapists create personalized programs that include core-strengthening, postural correction, and flexibility exercises—tailored to the patient’s age, curvature severity, and overall health.
Popular scoliosis-specific exercise methods include:
- Schroth Method
- SEAS (Scientific Exercises Approach to Scoliosis)
- Functional and postural training programs
Treatment Options for Scoliosis
Treatment plans are based on several factors: the patient’s age, curve degree and location, symptom severity, and risk of progression.
- Observation: For mild curves (under 20°), especially in growing children, doctors often recommend regular follow-ups to monitor changes over time.
- Bracing: In children or teens with moderate scoliosis (20°–40°), wearing a spinal brace may prevent curve progression during growth spurts.
- Physical Therapy: Tailored exercises help manage posture, reduce pain, and enhance muscle symmetry. Best suited for mild to moderate cases and adults with degenerative scoliosis.
- Surgical Treatment: In severe scoliosis (over 45°–50°), particularly when the curve progresses or causes functional limitations, spinal fusion surgery may be recommended. This is generally considered a last resort.
Causes of Scoliosis
Understanding the Underlying Factors Behind Spinal Curvature
Scoliosis can develop for a variety of reasons, and in many cases, the exact cause remains unknown. The condition can be congenital, neuromuscular, degenerative, or idiopathic—each with distinct origins and characteristics. Understanding these causes is essential for accurate diagnosis and personalized treatment planning.
1. Idiopathic Scoliosis (Most Common – Unknown Cause)
Idiopathic scoliosis accounts for up to 80% of all scoliosis cases, particularly in children and adolescents. It develops gradually during the growth spurt before puberty and is more common in girls. Although the exact cause is unclear, it is believed to involve genetic and hereditary factors.
There are three types:
- Infantile (0–3 years)
- Juvenile (4–10 years)
- Adolescent (11–18 years) — most common type
2. Congenital Scoliosis (Present at Birth)
This form of scoliosis results from abnormal spinal development in the womb. One or more vertebrae may be incompletely formed or fused together. Congenital scoliosis is often detected early and may progress as the child grows.
Possible causes include:
- Spinal malformations during fetal development
- Environmental or genetic factors affecting embryonic growth
3. Neuromuscular Scoliosis
This type is associated with neurological or muscular disorders that impair the spine’s ability to stay aligned. When muscles are weak or uncoordinated, they can’t support the spine properly.
It is commonly seen in individuals with:
- Cerebral palsy
- Muscular dystrophy
- Spinal cord injury
- Polio
- Spina bifida
This type usually progresses rapidly and often requires surgical intervention.
4. Degenerative Scoliosis (Adult-Onset)
Also known as adult scoliosis, this occurs due to age-related changes in the spine. As the discs and joints in the spine wear down over time, the spine can begin to curve.
Common contributing factors include:
- Osteoarthritis
- Disc degeneration
- Osteoporosis
- Spinal fractures or trauma
- Vertebral instability
This form of scoliosis is often accompanied by back pain, stiffness, and nerve compression symptoms such as leg numbness.
5. Functional or Postural Scoliosis
This is a temporary form of scoliosis caused by an external factor such as:
- Poor posture
- Leg length discrepancy
- Muscle spasms
- Herniated disc or inflammation
In these cases, the spine is structurally normal, and the curvature resolves once the underlying cause is treated.
Scoliosis in Children and Teenagers
Early Detection and Treatment for a Healthier Future
Scoliosis most commonly begins during the growth spurt just before puberty—typically between the ages of 10 and 18. This type is known as Adolescent Idiopathic Scoliosis (AIS) and accounts for nearly 80% of all scoliosis cases.
Why Early Detection Matters
In children and teenagers, scoliosis often progresses silently. Because it typically doesn’t cause pain in its early stages, it may go unnoticed until physical signs become more visible—such as uneven shoulders, an off-centered head, or a curved posture. That’s why routine scoliosis screenings at school or pediatric check-ups are essential.
What to Watch For
- Uneven shoulders or shoulder blades
- One hip higher than the other
- Ribs sticking out more on one side
- Tilted waistline or leaning to one side
- Clothes not fitting evenly
Treatment Options for Youth
Treatment depends on the degree of curvature, age, and stage of skeletal maturity. Options include:
- Observation: Mild curves under 20° are monitored regularly.
- Bracing: For curves between 20° and 40°, bracing may prevent further progression.
- Physical Therapy: Targeted scoliosis exercises (e.g., Schroth Method) can help realign posture and build core strength.
- Surgery: Only considered for curves over 45–50° or if the curve progresses rapidly.
Early intervention can prevent lifelong complications, reduce the need for surgery, and help children maintain a confident and active life.

Adult-Onset Scoliosis: Causes and Care
When Spinal Curvature Develops Later in Life
Adult scoliosis typically develops after age 40, and it’s often very different from adolescent scoliosis. This condition, known as Degenerative Scoliosis, is caused by age-related wear and tear on the spine, not growth.
What Causes Adult-Onset Scoliosis?
- Disc degeneration (the soft, cushioning discs between vertebrae shrink)
- Osteoarthritis and facet joint deterioration
- Bone loss due to osteoporosis
- Old injuries or spinal surgeries
- Poor posture or spinal imbalance over years
These factors can lead to an S- or C-shaped curve in the spine, often accompanied by pain, stiffness, nerve compression, or leg numbness.
Common Symptoms
- Chronic lower back pain
- Muscle fatigue or tightness
- Tingling or weakness in the legs
- Limited mobility or walking endurance
- Uneven hips or shoulders
How Is It Treated?
Treatment depends on severity and how much the condition affects daily life:
- Physical Therapy: To strengthen core and spinal muscles
- Pain Management: NSAIDs, cortisone injections, manual therapy
- Posture Training: Ergonomics and back bracing when needed
- Surgical Intervention: Recommended only when spinal instability or nerve compression causes major disability
Most adult scoliosis cases can be managed conservatively with personalized therapy programs, lifestyle adjustments, and non-invasive support. The goal is to improve quality of life and mobility without unnecessary surgery.
Frequently Asked Questions (FAQ)
Scoliosis is a medical condition where the spine curves sideways, usually in an “S” or “C” shape. It often develops during growth spurts in childhood or adolescence, but it can also occur in adulthood due to aging or spinal degeneration.
In most children and teenagers, scoliosis is painless. However, adults with scoliosis may experience chronic back pain, stiffness, or nerve compression.
Doctors perform a physical examination, including the “forward bend test,” and confirm the diagnosis with X-rays to measure the degree of spinal curvature (Cobb angle).
Treatment depends on age, curvature degree, and symptoms:
Observation for mild cases
Bracing to prevent progression in adolescents
Physical therapy for posture and muscle support
Surgery for severe or progressive curves
There is no proven way to prevent scoliosis, especially idiopathic types. However, early detection can prevent worsening of the curve.
Exercise cannot fully "correct" the spinal curve, but scoliosis-specific physical therapy can improve posture, muscle balance, and pain management.
No. Surgery is typically reserved for severe scoliosis (over 45–50°), rapid progression, or when the condition significantly affects quality of life or breathing.
Yes. Degenerative scoliosis occurs in older adults due to age-related spinal changes like disc degeneration, arthritis, or osteoporosis.
