Erector Spina Plan Block (ESPB) is a technique used in surgical interventions, acute and chronic pain. The aim of this study was to investigate the effect of ESPB and core stabilization exercises on functionality in patients with Lumbal Disc Herniation. ESPB will be applied to the patients in the study group. Stabilization exercises will be applied together with ESPB treatment. Only stabilization exercises will be applied to the patients in the control group. Patients will be asked to complete a questionnaire inquiring sociodemographic data (age, height, weight, BMI, smoking and alcohol use), VAS and Modified Oswestry Questionnaire at initial presentation and after 8 weeks of exercise (8 weeks 3 days a week).

Low back pain is defined as pain in the lower back and/or legs that negatively affects comfort. Low back pain lasting less than 6 weeks is defined as acute, 6-12 weeks as subacute, and more than 12 weeks as chronic low back pain. The goals of the exercise program include reducing pain, strengthening weak muscles, stretching tense muscles, reducing mechanical stress on spinal structures, mobilizing hypomobile segments and stabilizing hypermobile segments. Erector Spina Plan Block (ESPB) is a technique used in surgical interventions, acute and chronic pain. The aim of this study was to investigate the effect of ESPB and core stabilization exercises on functionality in patients with Lumbal Disc Herniation. ESPB will be applied to the patients in the study group. Stabilization exercises will be applied together with ESPB treatment. The needle will be inserted between the erector spinae muscle and the transverse process structures.The local anesthetic will be monitored to spread along the erector spinae muscle. Only stabilization exercises will be applied to the patients in the control group. Patients will be asked to complete a questionnaire inquiring sociodemographic data (age, height, weight, BMI, smoking and alcohol use), VAS and Modified Oswestry Questionnaire at initial presentation and after 8 weeks of exercise (8 weeks 3 days a week).
