Modifying Lumbar Flexion Pain Thresholds in Chronic LBP Using Virtual Reality and Visual-Proprioceptive Manipulation

The normal condition IS measured as a lumbar extension without VR until the onset of pain.

It involves an illusion with virtual reality where the patients perform a lumbar flexion until the onset of pain and they feel a 20% less movement in the VR (understated visual feedback)
