Abstract
Background Finding an optimal treatment strategy for adolescent idiopathic scoliosis (AIS) patients remains challenging because of its intrinsic complexity. For mild to moderate scoliosis patients with lower skeletal growth potential (Risser 3–5), most clinicians agree with observation treatment; however, the curve progression that occurs during puberty, the adolescent period, and even in adulthood, remains a challenging issue for clinicians. The aim of study is to investigate the efficacy of Schroth exercise in adolescent idiopathic scoliosis (AIS) patients with lower skeletal growth potential (Risser 3-5) and moderate scoliosis (Cobb angle 20-40°). Methods Data from 43 patients diagnosed with AIS and performed Schroth exercise were reviewed, and outcomes were measured by health-related quality of life (HRQOL) and radiographic parameters. HRQOL was assessed using the visual analog scale (VAS) scores for back, Scoliosis Research Society-22 (SRS-22) patient questionnaire. Radiographic spinopelvic parameters were obtained from anteroposterior and lateral X-rays. The pre-treatment and post-treatment HRQOL and radiographic parameters were tested to validate Schroth exercise efficacy.Results Vas back score, SRS-22 pain and SRS-22 self-image domain domain were significantly improved from pre-treatment 3.0±0.8, 3.6±0.5 and 3.5±0.7 to post-treatment 1.6±0.6, 4.0±0.3 and 3.7±0.4, respectively. No significant improvement of SRS-22 function domain and mental health domain. The mean Cobb angle decreased from 28.9±5.5° to 26.3±5.2° at the final follow-up, despite no statistical significance was observed. The mean C2-C7 sagittal vertical axis (SVA) value decreased from 21.7±8.4 mm to 17.0±8.0mm and mean T1 tilt decreased from 4.9±4.2 ° to 3.5±3.1°. No other significant improvement of radiographic parameters was observed.Conclusions For AIS patients with a Risser 3–5 and a Cobb angle 20°–40°, Schroth exercises improved HRQOL and halted curve progression during the follow-up period. Both cervical spine alignment and shoulder balance were also significantly improved after Schroth exercises. We recommend Schroth exercises for patients with AIS.
