Chronic Low Back Pain, Fear of Injury, Fear of Pain
Conditions
Brief summary
This study will measure the effects of interactive, whole-body video games on movement behavior in people with chronic low back pain.
Detailed description
A fundamental clinical problem in individuals with chronic low back pain is the significant alteration in movement patterns that restrict lumbar spine motion. This restriction of lumbar motion is particularly evident in patients with kinesiophobia; that is, a fear of movement due to possible injury or reinjury. For chronic back pain patients with kinesiophobia it is critical to develop an effective intervention to increase spine motion while minimizing concerns of pain and harm. Accordingly, we have developed a innovative video games that track whole-body motion and are designed to encourage spinal flexion while reducing concerns of pain and harm among individuals with low back pain. Our games have two distinct advantages. First, within this video game environment, visual feedback can be altered by changing the feedback gain of a given movement (e.g., the magnitude of a given joint movement could appear on screen as either larger or smaller than the actual movement). Thus, gain manipulation will result in progressively larger amounts of lumbar spine flexion during game play. Second, video games are potent distractors that can reduce attention to pain.
Interventions
Participants will complete 18 intervention visits over 9 weeks with the number of sessions tapered across weeks (i.e., 3 sessions/week in weeks 1-3, 2 sessions/week in weeks 4-6, and 1 session/week in weeks 7-9).

Study design
Masking description
The principal investigators, the statistician, and members of the data collection team will remain blinded to intervention assignment throughout the duration of the study. They will be given the identifying codes only at the end of the study when it is necessary to interpret the results. The un-blinded study coordinator, who is responsible for scheduling testing and treatment sessions, will serve to receive the study patients and escort them to the various testing and treatments sites to minimize the interaction between patients; however, the study coordinator will not participate in the assessments.
Intervention model description
Participants will be randomly assigned to one of two intervention arms. Both intervention arms involve immersive video games that encourage participants to produce progressively larger lumbar flexion excursions at each game level and across treatment sessions. The two groups are distinguished by the amount of lumbar flexion needed to achieve game objectives. One is a control group and the other is the experimental.

| Percent Change in Pain Reduction on The Numerical Pain Rating Scale (NPRS) | Baseline measure through the 48-weeks post-treatment measure | The Numerical Pain Rating Scale (NPRS) is a pain assessment tool that uses a 11 point scale of 0-10 to help patients rate the intensity of their pain: 0: No pain and 10: The worst pain imaginable. The NPRS is the most commonly used unidimensional pain scale. It can be administered verbally or graphically, and patients are asked to select the number that best reflects their pain intensity over the past 24 hours. The smaller the number (closer to 0), the less pain the subject is enduring, and the larger the number, the more pain they are enduring. Percent change in NPRS rather than raw score change may provide more meaningful information regarding a patient's response to pain treatment. |

The patient is asked to tick a statement when it applies to him that specific day, this makes it possible to follow changes in time. The end score is the sum of the ticked boxes. The items of the questionnaire are assessed on a 0-10 numeric rating scale in which 0 means no disability and 10 is maximum disability. The sum of the seven items equals the total score of the PDI, which ranges from 0 to 70, with higher scores (closer to 70) reflecting higher interference of pain with daily activities and a lower score (closer to 0) has less interference of pain with daily activities..
