ABSTRACT
Background: Non-specific low back pain (NSLBP) is a leading cause of disability worldwide. Traditional physiotherapy often focuses on general strengthening and posture correction, whereas core and diaphragmatic strengthening exercises target both spinal stability and respiratory function. However, the comparative effects of these two approaches on core stability, forced vital capacity (FVC), and clinical outcomes have not been adequately studied.
Objective: To compare the effects of core and diaphragmatic strengthening exercises versus standard physiotherapy on core stability, forced vital capacity, and clinical outcomes in individuals with non-specific low back pain.
Methods: This prospective cohort study involved 60 participants diagnosed with NSLBP. Participants were assigned to two groups based on their treatment preferences or clinical indication: Group 1 (Core and Diaphragmatic Strengthening) and Group 2 (Standard Physiotherapy). Group 1 received exercises aimed at improving core stability and diaphragmatic function, while Group 2 received standard physiotherapy focused on general strengthening, stretching, and postural education. Outcomes were measured at baseline, 4 weeks, and 8 weeks, including core stability (McGill Trunk Muscle Endurance Test), forced vital capacity (spirometry), and clinical outcomes (Visual Analog Scale for pain and Oswestry Disability Index).
Results: Both groups showed significant improvements in core stability, FVC, and clinical outcomes. Group 1 demonstrated greater improvements in trunk endurance (p<0.05) and forced vital capacity (p<0.05) compared to Group 2. Additionally, pain and disability scores improved more significantly in Group 1, with a greater reduction in VAS (p<0.05) and ODI (p<0.05).
Conclusion: Core and diaphragmatic strengthening exercises appear to be more effective than standard physiotherapy in improving core stability, forced vital capacity, and clinical outcomes in individuals with non-specific low back pain. These findings suggest that incorporating core and diaphragmatic exercises into rehabilitation programs for NSLBP may lead to better outcomes.
