The Schroth Method Halts Curve Progression
and Avoids Spinal Fusion Surgery
A growing literature written by physical therapists documents the results of Schroth exercise therapy for scoliosis. Abundant evidence in clinical studies, some of them cited below, demonstrates that the Schroth method can stop curve progression in adolescents, reverse abnormal curves, reduce pain, increase vital capacity, and avoid surgery.
Treatment is not uniformly successful in every case. Success is influenced by factors that include diagnostic and treatment skill, the degree of curvature, age of the patient, and patient compliance in performing the exercises.
Schroth Therapy Reduces Curves, Avoids Surgery
A Schroth clinic in Spain reports surgery rate as low as 5.6%
Since 1991, Dr. Manuel Rigo's clinic in Barcelona has practiced bracing and physical therapy for adolescent idiopathic scoliosis (AIS). His scoliosis database was searched for patients with AIS who were at least 15 years of age at last review and who had adequate documentation of their Cobb angle.
Of 106 braced cases ( 97 followed up), only six cases (5.6%) ultimately underwent spinal fusion.
Even if all nine cases from whom data could not be obtained had undergone surgery, the greatest number of spinal fusion cases would be 15 (14.1%). In contrast, published data from an Irish center with a policy of non-intervention reported surgeries on 28.1% of their AIS patients.

Schroth patients are much less likely
to suffer curve progression
Two independent patient groups matched by age and sex at diagnosis were analyzed using the outcome parameter, incidence of progression (> or =5 deg ). One group was untreated and the other received scoliosis in-patient rehabilitation (SIR) at the Katharina-Schroth-Klinik, Bad Sobernheim, Germany. Untreated patients progressed 1.5 to 2.9 times more than those treated with SIR, even though some SIR-treated patients had more severe curvatures

No curve progression in Schroth patients
3 years after treatment
This preliminary study begun in 1989 included 181 scoliosis patients, average age 12.7 years, average Cobb angle curvature 27 degrees, average risser sign 1.4, average follow-up 33 months.
Results of the preliminary study were compared to natural history as known from literature. For the worst-case analysis additionally a questionnaire was sent to the non-repeaters who had been treated at the same time (1989 and 1990) as the patient sample, using essentially the same inclusion criteria.
Results showed no curve progression (defined as increase in curvature of 5+ deg/yr). The lack of progression of the 181 patients from the preliminary study and the 116 questionnaire patients together exceeded natural history even if all drop-outs were considered failures.

Some Schroth exercises for spinal fusion patientsSpinal fusion surgery does not eliminate the need for physical therapy to correct patients' posture and maintain stability above and below the fused segment. Nine exercises are described and depicted.

A review of the literature finds high rate of complications for spinal fusion surgery, and no evidence for recommending surgeryThe authors find no evidence that spinal fusion can alter health related signs and symptoms of scoliosis in the long term, thus we cannot derive a clear medical indication for surgery.
For this review, English-language articles and bibliographies in Pub Med and the SOSORT scoliosis library were searched for the terms: 'scoliosis'; 'rate of complications'; 'spine surgery'; 'scoliosis surgery'; 'spondylodesis'; 'spinal instrumentation' and 'spine fusion.' An electronic search on the keywords "scoliosis", "surgery", and "rate of complications" found 287 titles.
Rates of complication varied between 0 and 89% depending on the etiology of the entity investigated. There are no reports on long-term rates of complications from surgery.
This varying but high rate of complications may be even higher than reported. A medical indication for surgical treatment cannot be established, because of lack of evidence to support it. This study recommends mandatory, standardized reporting for all spinal implants using a spreadsheet list of all recognized complications to show a 2-year, 5-year, 10-year and 20-year rate of complications.

Comparison study: Schroth patients had surgery at only 25% to 43% the rate of untreated patients (1993-1996)
The study compares incidence of surgery in two groups of scoliosis patients: 343 who had conservative treatment at the Schroth clinic between 1993 and 1996, and 153 patients reported by a center in Ireland in 2001.* All were at least 15 years of age at the time they were last investigated or questioned.
Schroth subjects were 343 females, curvature averaged 33.4 deg (standard deviation = 18.9), followed up by questionnaire. Forty-one of them (12%) had gone on to have surgery, as recommended by their home physician. But this incidence of surgery was only 7.3% of Schroth AIS paitents, compared with 28% in the control group with the same diagnosis. Our conservatively treated early-onset and congenital scoliosis patients had a higher incidence of surgery (20.8% and 22.2%), yet still lower than the control group.
Statistically, the incidence of surgery in the Schroth groups was significantly lower than the incidence of surgery in the control group from Ireland and other centers described in literature.

Literature review validates conservative treatmentA review of clinical literature reveals that scoliosis normally does not have such dramatic effects that would justify immediate surgery. Out-patient physiotherapy, intensive in-patient rehabilitation, and bracing have proven effective in conservative scoliosis treatment in central Europe. The positive outcomes of this practice validate a policy of offering conservative treatment as an alternative to scoliosis patients.

Review of literature finds evidence to support conservative treatment of AIS, but no controlled study supports surgery for scoliosisTraditional treatment options (in Germany) for adolescent idiopathic scoliosis (AIS) are exercises; in-patient rehabilitation; braces; and surgery.
The largest medical databases were searched for the outcome parameter "'rate of progression," targeting prospective controlled studies that considered the treatment versus natural history.
Search strategy included the terms: ''adolescent idiopathic scoliosis''; ''idiopathic scoliosis''; ''natural history''; ''observation''; ''physiotherapy''; ''physical therapy''; ''rehabilitation''; ''bracing''; ''orthotics;'' and ''surgery''.
Prospective short-term studies were found to support outpatient physiotherapy. One prospective controlled study supported scoliosis in-patient rehabilitation (SIR). Bracing is supported by one prospective multi-center study, a long-term prospective controlled study, and a meta-analysis.
No controlled study over any time span produced substantial evidence to support surgery as a scoliosis treatment. No evidence in prospective controlled studies supports surgical intervention.
Because of unknown long-term effects of surgery, a randomized controlled trial (RCT) seems necessary. However, due to evidence supporting conservative treatments, a RCT for conservative treatment options may be unethical.
Some evidence supports conservative treatment for AIS. However, this evidence for conservative treatment is admittedly weak in number and length of studies.

Arguments for and against spinal fusion surgery for scoliosisDespite vast clinical research and published treatment guidelines and algorithms, the optimal therapeutic choice for AIS patients remains controversial. Advocates of early surgery emphasize the benefits of surgical deformity correction with regard to physical and psychological outcome. Opponents base their arguments on the high risk of complications and a lack of documented subjective long-term outcome.

Patients with congenital scoliosis benefit from Schroth treatmentThe paper addresses current practice of recommending early surgery for patients with congenital scoliosis (CS), even in mild cases of formation failures in the first three years of life.
Two patients with rib synostosis denied surgery before entering the pubertal growth spurt. These patients were treated with braces and Scoliosis In-Patient Rehabilitation (SIR) and now are beyond the pubertal growth spurt. One patient with a formation failure and a curve of greater than 50 degrees lumbar was treated with braces and physiotherapy from 1.6 years and was still under treatment at age 15.
Severe decompensation was prevented in the two patients with failure of segmentation. However, a severe thoracic deformity is evident, with underdeveloped lung function and severe restrictive ventilation disorder.
The patient with failure of formation is well developed, currently with no cosmetic or physical complaints, although his curve progressed at the end of the growth spurt due to final malcompliance.
CONCLUSIONS: Failures of segmentation should be advised to have surgery before entering the pubertal growth spurt. If they refuse, c onservative treatment can be partially beneficial. Conservative rather than surgical treatment should be recommended for patients with failures of formation, because long-term outcomes of early surgery beyond pubertal growth spurt are still undocumented.
