This study evaluates whether progressive relaxation exercises can reduce fear of movement, pain, and improve quality of life in patients with lumbar disc herniation. Participants are randomly assigned to either a control group receiving standard care or an intervention group performing supervised relaxation exercises in addition to standard care. The exercise program is conducted three times per week for 15 sessions. Outcomes are measured before and after the intervention using validated scales assessing kinesiophobia, pain intensity, disability, and quality of life. The goal is to determine whether adding relaxation exercises provides additional benefits for patients with lumbar disc herniation.
