Long-term Effectiveness of Integrative Scoliosis-specific Rehabilitation in High-risk Adolescent Idiopathic Scoliosis
Long-term Effectiveness of Integrative Scoliosis-specific Rehabilitation in High-risk Adolescent Idiopathic Scoliosis
Adolescent idiopathic scoliosis (AIS) is one of the most common spinal deformities diagnosed in adolescents, especially female, with the prevalence in general population ranging from 0.93% to 12%, 80% of which are idiopathic. The management and treatment of AIS includes observation, physiotherapy (or therapeutic exercise), brace application, and surgery. Evidence of the conservative management of AIS has been stronger in recent years. However, the best combination therapy has not been well established. Moreover, the investigator has demonstrated an innovation of pattern-specific manual therapy to treat AIS. Different from previous conservative treatment, the investigators applied specific treatment for different patterns of AIS according to the Lehnert-Schroth (LS) scoliosis classification. Therefore, the investigators aim to determinate the long-term effects of the integrative scoliosis-specific rehabilitation program combining pattern-specific manual therapy, Schroth Best Practice (SBP) exercise, and Gensingen brace application in treating AIS patients.
Adolescent idiopathic scoliosis (AIS) is one of the most common spinal deformities diagnosed in adolescents, especially female, with the prevalence in general population ranging from 0.93% to 12%, 80% of which are idiopathic. It is a complex 3D structural disorder, diagnosed when the Cobb angle is equal to or greater than 10 degrees, accompanied by vertebral rotation. The risk factors of curve progression include growth spurt, positive family history, laxity of skin and joints, flat back, and angle of trunk rotation more than 10 degrees. Curve progression can lead to aesthetic concerns, spinal pain syndromes, and respiratory dysfunction.
The management and treatment of AIS includes observation, physiotherapy (or therapeutic exercise), brace application, and surgery. According to Lonstein et al, a progression factor, which is used for the risk assessment of curve progression of progression, is calculated using the Risser sign, age at presentation, and magnitude of the curve. A probability for progression of under 40% is indicated for observation only, while the probability for progression of 40% - 60% is indicated for physiotherapy, and the probability for progression of over 60% is considered indicated for bracing application. Current evidence recommended that bracing be applied in evolutive AIS patients (Risser 0 to 3) with curves above 20° ± 5° Cobb.
Current studies have investigated the efficacy of conservative treatment for AIS. In terms of bracing, previous studies have shown that AIS patients treated with Rigo Chêneau orthoses had lower major curve progression versus those with Boston-style orthoses. Furthermore, the Gensingen brace is developed from Chêneau brace with individual computer-aided design, which exhibits efficacy in decreasing Cobb angle and angle of trunk rotation. There are a wide range of physiotherapeutic scoliosis-specific exercise methods, among which the Schroth exercise program is the mostly studied and is proven to be effective. The Schroth method consists of postural, sensorimotor, and corrective breathing exercises in daily activities for three-dimensional correction of the patients' specific curve patterns.
A randomized-controlled study in 2016 revealed that Schroth exercise program was superior to home exercise and control groups in decreasing the Cobb and rotation angles. In addition, a randomized-controlled study in 2016 revealed that adding Schroth physiotherapeutic scoliosis-specific exercises to standard care of bracing can lead to better reduction of curve severity than bracing alone in treating AIS patients. Also, long-term improvement of combining Schroth exercise and Chêneau orthoses has been observed. On the other hand, manual therapy in treating AIS is less studied, and current evidence is insufficient to confirm the benefit of manual therapy in AIS patients. This study applied a pattern-specific manual therapy to mobilize and realign the asymmetry of the spine and extra-spinal regions.
