Abstract: Flat back syndrome (FBS) is a sagittal imbalance wherein the normal spinal curvature is reduced. This study aimed to compare the effects of different exercise programs on the cross-sectional area (CSA) of the lumbar muscles, lumbar lordosis angle (LLA), lumbar disability, and flexibility in patients with FBS. Thirty-six females with flexible FBS were randomly allocated to the corrective exercise group (CEG, n = 12), resistance exercise group (REG, n = 12), and physical therapy group (PTG, n = 12). CEG and REG patients participated in a 12-week exercise intervention for 60 min three times per week. The CSA, LLA, Oswestry disability index (ODI), and sit-and-reach test were measured before and after intervention. CSA showed a significant difference between groups ( p < 0.01), with CEG and REG demonstrating a significant increase ( p < 0.05 and p < 0.05, respectively). LLA showed a significant difference between groups ( p < 0.001); CEG showed a higher increase than did REG ( p < 0.01) and PTG ( p < 0.001). ODI also showed a significant difference between groups ( p < 0.001), being lower in CEG than in REG ( p < 0.001) and PTG ( p < 0.001). Lumbar flexibility significantly improved in all groups, albeit with a significant difference ( p < 0.001). Although corrective and resistance exercise programs effectively improve these parameters, corrective exercise is superior to other interventions for patients with FBS.
