Schroth therapy is a specialized form of physical therapy designed to treat scoliosis by correcting spinal curves in three dimensions. Rather than general stretching or strengthening, it uses a combination of targeted exercises and a unique breathing technique to de-rotate, elongate, and stabilize the spine. Originally developed in 1921 by Katharina Schroth, a German woman who had scoliosis herself, the method remains one of the most widely studied and practiced conservative treatments for scoliosis worldwide.
How the Method Works
Scoliosis isn’t just a side-to-side curve. The spine also rotates and shifts forward or backward, creating a three-dimensional deformity. Schroth therapy addresses all three planes of movement at once, which sets it apart from general physical therapy.
The exercises target a specific imbalance that develops in the muscles surrounding a scoliotic spine. On the concave side of the curve, muscles tend to weaken and waste away from disuse. On the convex side, they become overworked and prominent. Schroth exercises aim to restore muscular symmetry by lengthening shortened tissues on one side and strengthening weakened tissues on the other. Patients learn corrected postures tailored to their individual curve pattern and practice holding those positions during exercises and daily activities.
A hallmark of the method is rotational angular breathing, a technique where you deliberately direct your breath into the concave (collapsed) side of your ribcage. This expands the compressed area from the inside out, helping reshape the rib cage and the soft tissue around it over time. Katharina Schroth originally discovered this principle by experimenting on her own body, observing how changes in her breathing patterns altered the shape of her torso.
What a Session Looks Like
Schroth therapy typically begins with an individualized assessment. A trained therapist evaluates your specific curve pattern, because the exercises differ significantly depending on where the curve is and how it’s shaped. Sessions commonly last 60 to 90 minutes and take place one to three times per week, though protocols vary.
In clinical studies, a common structure involves an initial block of individual sessions (often around five) to learn the fundamentals, followed by a longer period of weekly group sessions combined with a daily home exercise program of 30 to 45 minutes. Some programs run for 6 weeks, others for 6 months. One study found measurable curve reduction after 12 weeks of supervised sessions performed three times per week for 60 minutes each.
Sessions use simple equipment: wall bars for traction and stretching, mirrors so you can monitor your posture in real time, and sometimes props to help you feel which muscles to activate. The mirror is particularly important because scoliosis distorts your sense of what “straight” feels like. Visual feedback helps you learn to recognize and maintain corrected alignment on your own.
What the Research Shows
A systematic review and meta-analysis published in the European Journal of Physical and Rehabilitation Medicine pooled results from six randomized controlled trials and found that Schroth exercises reduced spinal curvature (measured by Cobb angle) by an average of about 3.2 degrees compared to no treatment or other conservative approaches. The method also improved trunk rotation and quality-of-life scores.
That 3.2-degree improvement is meaningful context, but it falls short of the 5-degree threshold that clinicians typically consider the minimum for a clearly noticeable clinical change. This doesn’t mean the therapy is ineffective. For many people with scoliosis, the primary goals are stopping a curve from getting worse, reducing pain, and improving posture and function. In adolescents whose spines are still growing, even modest improvements or stabilization can make a significant difference in long-term outcomes. The studies analyzed generally lasted two to six months, so longer-term effects could potentially be larger with continued practice.
Who It’s Best Suited For
Schroth therapy is primarily designed for people with idiopathic scoliosis, the most common type, which has no identifiable underlying cause and typically appears in adolescence. The International Scientific Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) includes Schroth-based exercises in its guidelines for preventing scoliosis progression during growth. SOSORT also recommends these exercises as a complement to bracing and even during surgical treatment periods.
The method is generally not used for scoliosis caused by neurological or rheumatic diseases, nor for people who have already had corrective spinal surgery. Other situations where Schroth therapy may not be appropriate include any general contraindication for exercise or cases where surgery is already scheduled. Adults with scoliosis can and do use the method for pain management and postural improvement, though most of the clinical research has focused on adolescents.
Schroth Therapy and Bracing
Schroth exercises are often used alongside a brace rather than as a replacement for one. For moderate curves in growing adolescents, bracing remains the primary conservative intervention, and Schroth therapy serves as a complement. The exercises can help maintain muscle strength and mobility that might otherwise decline during prolonged brace wear. For mild curves that don’t yet meet the threshold for bracing, Schroth therapy may be used as a standalone treatment to try to prevent progression.
Finding a Qualified Therapist
Not every physical therapist is trained in the Schroth method. The technique requires specialized certification beyond a standard physical therapy degree. One of the main certifying organizations is the Barcelona Scoliosis Physical Therapy School (BSPTS), which teaches the Rigo Concept, a modern evolution of the original Schroth method. Their certification involves four levels of training, from a foundational online course through advanced hands-on levels. Only therapists who complete all four levels can identify themselves as certified members. SOSORT recognizes Schroth-based approaches as meeting the criteria for physiotherapy scoliosis-specific exercises.
When searching for a provider, look for therapists who specifically list Schroth certification or scoliosis-specific exercise training. General orthopedic physical therapists, even excellent ones, may not have the specialized knowledge to classify your curve pattern and prescribe the correct exercises. Since every exercise is tailored to your specific curve type, working with the wrong protocol could be ineffective or counterproductive.
