Abstract
PURPOSE: To investigate the change of pulmonary function in adult scoliosis patients with respiratory dysfunction undergoing HGT combined with assisted ventilation. METHODS: 21 adult patients were retrospectively reviewed with a mean age of 26.2 years. Inclusion criteria were as follows: age over 18 years old; coronal Cobb angle greater than 100°; with respiratory failure; and duration of HGT more than 1 month. All patients underwent respiratory training. RESULTS: The Cobb angle averaged 131.21° and was reduced to 107.68° after HGT. Significantly increased mean forced vital capacity (FVC) was found after HGT (P = 0.003) with significantly improved percent-predicted values for FVC (P < 0.001). Meanwhile, significantly increased forced expiratory volume in 1 s (FEV1) was also observed (P < 0.001) with significantly improved percent-predicted values for FEV1 (P = 0.003) after HGT. CONCLUSION: The results of our study revealed that combined HGT and assisted ventilation would be beneficial to pulmonary function improvement in severe adult scoliosis cases, most of which were young adults.
