Forty adolescents with idiopathic scoliosis (Cobb angles 10°–25°) were randomised to receive either spinal mobilisation combined with core stabilisation exercises (CSE) (n=20) or CSE alone (n=20). The primary outcome of interest was the Cobb angle, while secondary outcomes included angle of trunk rotation (ATR) and pulmonary function tests (PEF, FEV1, FVC, and FEV1/FVC). Outcomes were assessed at baseline and after 10 weeks of treatment. Overall, the study found that both groups showed significant improvements in Cobb angle, ATR, PEF, and FVC, with the experimental group demonstrating significantly greater reductions in Cobb angle compared to the control group. The experimental group also showed an improvement in FEV1, whereas the control group did not. No significant changes were observed in FEV1/FVC in either group. These findings suggest that spinal mobilisation can enhance the conservative management of AIS by improving spinal alignment and respiratory function.
