Feasibility of an Augmented Reality Novel Approach for the Rehabilitation of Chronic Low Back Pain Patients With Kinesiophobia

The goal of this clinical trial is to evaluate the feasibility, safety, and initial effectiveness of a new augmented reality (AR) system in adults over 18 years old suffering from chronic low back pain and kinesiophobia (fear of movement). The main questions it aims to answer are: Is the AR system safe to use and well-tolerated by participants without causing significant motion sickness or discomfort? Can the visual "illusion" provided by the AR technology help patients increase their range of motion and reduce their fear of bending forward? Participants will: * Perform 10 to 12 repetitions of spinal bending exercises while wearing an AR headset that shows a video of them moving further than they actually are. * Complete questionnaires regarding their pain levels, physical disability, and fear of movement. * Report any symptoms of "cybersickness" (like dizziness or nausea) experienced during the use of the technology. * Participate in a brief interview to discuss their experience, how they felt using the device, and provide suggestions for improvement.
