The goal of this clinical trial is to test a home-based virtual reality rehabilitation application in patients with chronic low back pain. The main question it aims to answer are: Is a prototype of a novel VR software application effective at reducing pain, improving daily function, improving range of motion, and reducing fear of movement in adult patients with chronic low back pain compared with a passive VR intervention? Participants in the treatment group will use the application daily for 20 minutes for a period of 3 weeks at home and unsupervised. Researchers will compare use of the VR application with a control group that watches 2D video to see if the treatment group have improved pain, disability, range of motion, and fear of movement.
