Investigation of the Effects of Inspiratory Muscle Training on Patients With Mechanical Low Back Pain.

When initial assessment will be completed, patients will be assigned to one of two possible sequences by simple randomization: study group (SG) or control group (CG). All participants will receive the core stabilization exercise program designed for mechanical low back pain for 8 weeks. Additionally, the study group will receive inspiratory muscle training for 8 weeks. All studies will be evaluated both at the beginning and end of the study in terms of pain, quality of life, sleep quality, disability level, muscle endurance and functional capacity. All data will be collected by the same physiotherapist at baseline and at the end of the study (8 weeks). The same physiotherapist will also supervise the exercises and inspiratory training.
