Background: Incorrect postures of adolescents caused by the use of smart devices have been noted as a factor causing spinal diseases.
Objectives: To examine the effect of joint mobilization and stretching on Cobb’s angle and respiratory function in adolescent idiopathic scoliosis (AIS).
Design: Cluster-randomized controlled trial.
Methods: A total of 22 subjects with AIS were enrolled. They were allocated to two groups: the joint mobilization (n=11) and the stretching (n=11). All interventions were conducted for 30 minutes, three times a week for six weeks. Outcome measures were the Cobb’s angle and respiratory function. The Cobb’s angle and respiratory function measured using the X-ray and Micro- Quark.
Results: Joint mobilization group showed significant differences in Cobb’s angle and respiratory function, but stretching group showed significant differences Cobb’s angle. The differences in peak expiratory flow (PEF) between the two groups were significant.
Conclusion: This study proved that joint mobilization is a more effective intervention for AIS to improve Cobb’s angle and respiratory function, when compared to stretching.
