This multi-site study aims to investigate the feasibility, safety, and efficacy of using embodied virtual reality graded motor imagery software to treat adults with diagnosed chronic central pain conditions in two bodily regions: chronic pain in the lower back and in the upper limbs. The research will be conducted in two phases, the second of which is contingent upon successful completion of the first. The first phase will involve piloting a novel virtual reality treatment for chronic pain to investigate feasibility and safety with a smaller number of patients (N=30 for each condition). The second phase of the research will investigate efficacy using a single-blinded randomized control study design with sham control. Chronic pain conditions of the lower back and upper limbs will be investigated separately, and power analyses have been conducted to determine optimal study size, which is N=200 for each portion. Central pain is defined as pain that originates in the central nervous system, and is not immediately due to injury, but is possibly a delayed reaction to injury. Example conditions eligible for this study include chronic lower back pain, as well as phantom limb pain, complex regional pain syndrome, carpal tunnel syndrome, post-stroke limb pain, and repetitive strain injuries of the shoulder, arm or hand. In the pilot phase of the study, 30 subjects with chronic lower back pain and 30 subjects with chronic upper limb pain will receive 8 sessions of graded motor imagery virtual reality therapy. Contingent on the success of the pilot, defined as completion of 8 session with no adverse events, and trends indicating improvement of range of motion, pain, fear/avoidance, and depression symptoms, the randomized control trial phase of the research will proceed. In the randomized phase, subjects will be randomized into active or control conditions. Active condition subjects will receive 8 sessions of graded motor imagery in virtual reality, and control condition subjects will receive a non-embodied sham virtual reality experience. This study will investigate the safety and feasibility of this approach, as well as its effects on pain symptoms. This product is considered a non-significant risk device, as is explained in the accompanying letter from the sponsor, Karuna Labs Inc. A request for feedback from the presubmission program of the U.S. Food and Drug Administration has additionally been submitted.
