The efficacy of Schroth exercises combined with the Chêneau brace for the treatment of adolescent idiopathic scoliosis: a retrospective controlled study.

PURPOSE

We aimed to determine the global effects of the Chêneau brace combined with Schroth exercises on adolescent idiopathic scoliosis (AIS).

METHODS

We analyzed 192 patients with AIS who underwent the Chêneau brace treatment alone or combined with Schroth best practice (SBP) from June 2013 to October 2019. There were 138 patients in the Brace group and 54 patients in the Brace + SBP group. Radiographs were obtained at various treatment durations. Answers to the health-related quality of life (HRQoL) questionnaire were recorded before the intervention and at the time of treatment wean.

RESULTS

The Cobb angle (-3.55°;  < 0.001) and C7-CSVL (-3.03 mm;  < 0.001) significantly decreased in the Brace + SBP group. Thoracic kyphosis (TK) decreased in both the Brace + SBP group (-1.85°;  = 0.0152) and the Brace group (-5.06;  < 0.001). Changes before and after treatment of TK were significantly different between groups ( < 0.001). The 22-item Scoliosis Research Society function score, self-image, mental health, and EuroQol 5-Dimension scores were significantly higher in the Brace + SBP group. The satisfaction score was higher in the Brace + SBP group (3.77 ± 0.63 vs. 3.13 ± 0.79;  < 0.001).

CONCLUSIONS

Compared to bracing alone, the Schroth exercises plus bracing had a better effect on coronal balance. Schroth exercises improve flatback deformity caused by bracing and positively influence the HRQoL in AIS patients who received the Chêneau brace treatment.Implications for RehabilitationBracing and physiotherapy are common treatments for adolescent idiopathic scoliosis (AIS).The Chêneau brace treatment causes flatback deformity and muscle stiffness in AIS patients.The Schroth method helps patients increase muscle strength, halt curve progression, increase vital capacity, and maintain improved posture.The Schroth exercises could improve flatback deformity caused by bracing and positively influence the health-related quality of life in AIS patients who received the Chêneau brace treatment.
