- Brief Summary
The aim of this study is to provide critical information about the efficacy of Immersive Virtual Reality (IVR) to decrease the experience of neuropathic pain in the upper and lower extremities of people with a spinal cord injury.
- Detailed Description
When a spinal cord injury occurs, the spinal somatosensory circuit is thought to generate aberrant nociceptive impulses that the brain interprets as pain. Neuropathic pain (NP) affects 40 to 70% of people with SCI and is a very disabling clinical condition. Many treatment options have been offered, but provide limited effects, leaving people with SCI with a reduced quality of life. The study team believes that Immersive Virtual Reality (IVR) neurorehabilitation has the potential to be an effective treatment for chronic neuropathic pain. For this reason, the objective of this study is to evaluate the feasibility of using a virtual reality device to decrease chronic neuropathic pain in individuals with spinal cord injury.

Group Intervention Description Distractive IVR Distractive IVR (dIVR) Participants with participate in Distractive IVR protocol three times per week for four weeks. Control IVR Control IVR (cIVR) Participants with participate in Control IVR protocol three times per week for four weeks. Somatic IVR Somatic IVR (sIVR) Participants with participate in Somatic IVR protocol three times per week for four weeks.
- Primary Outcome Measures
Name Time Method Neuropathic Pain Symptom Inventory (NPSI) Up to 10 Weeks Neuropathic Pain Symptom Inventory (NPSI): This scale was developed to assess both the quantitative and qualitative qualities of neuropathic pain (NP). It includes 12 items, assessing spontaneous pain, brief attacks of pain, provoked pain and abnormal sensations in the painful area. This is a sensitive tool for measuring changes in neuropathic pain after a therapeutic intervention. Total score range for NPSI is 0-100, higher scores indicate more severity.
- Secondary Outcome Measures
Name Time Method Spinal Cord Independence Measure (SCIM III) Up to 10 Weeks Spinal cord independence measure (SCIM III) measures the ability of patients with SCI to perform everyday tasks. SCIM is used for quantitative functional outcome assessment following interventions designed to promote recovery from spinal cord injury and to increase functional achievement; it covers 19 tasks in 16 categories, with a score range 0-100; all activities of daily living, grouped into four areas of function (subscales): Self-Care (scored 0-20), Respiration and Sphincter Management (0-40), Mobility in Room and Toilet (0-10), and Mobility Indoors and Outdoors (0-30). VR neurorehabilitation has shown to improve motor function as well as to reduce neuropathic pain in incomplete SCI patients. The study team is planning to monitor the effects that this IVR protocol has in motor recovery. Total score range for SCIM II is 0 - 100, where a score of 0 defines total dependence and a score of 100 is indicative of complete independence.
Immersive Tendencies Questionnaire (ITQ) Up to 10 Weeks Immersive tendencies questionnaire (ITQ): In the field of virtual reality, presence and immersion are standard measures of an individual's sense of engagement and involvement in an activity. The study team expects that high levels of immersion might indicate greater engagement and therefore reduction of the pain. Total score range for ITQ: 18 - 126.
User Experience Score (UES) 14 Days Participants rate their experience using the technology on a scale with a total score range of 0 to 10, where 0 means no enjoyment and 10 means very high levels of enjoyment.
Numerical Pain Rating Scale (NPRS) 16 Days Users report the score of both neuropathic and other pain. The total score range is from 0 to 10, lowest score indicating 0, "No pain" and highest score indicating 10, "Pain as bad as it could be". The type of "other" pain will also be recorded (musculoskeletal, etc).
Beck Depression Inventory (BDI) Up to 10 Weeks Beck Depression Inventory (BDI): Depression symptoms are estimated to be highly prevalent in SCI population and are associated with a myriad of negative outcomes including lower functional independence, and greater incidence of pain. This questionnaire is a 21-item, self-report rating inventory that measures characteristic attitudes and symptoms of depression. Depression may be a major contributor to a lack of reduction of pain, the study team expects subjects with high BDI score may have worse results after the IVR. Total score range for BDI is 0 - 63; scores from 0 through 9 indicate no or minimal depression; from 10 through 18 indicate mild to moderate depression; from 19 through 29 indicate moderate to severe depression; and from 30 through 63 indicate severe depression.
Patient's Global Impression of Change (PGIC) Up to 10 Weeks Self-reported relieving effect: At the end of the treatment (post-intervention), the Patient's Global Impression of Change (PGIC) will evaluate both motor function and pain. The total score range includes no change (score 0-1), minimally improved (score 2-3), much improved (score 4-5), and very much improved (score 6-7) as the highest score. The patients will answer the following question: "Since beginning treatment at this program, how would you describe the change (if any) in activity limitations, symptoms, emotions, and overall quality of life related to your condition?".
UQO- Presence Questionnaire (UPO-PQ) 16 Days The UQO Presence questionnaire (UQO-PQ): Presence can be a major factor that determines the quality and success of a virtual environment implementation. Several factors such as impression of being present, realness, and discomfort are measured in this questionnaire. The questionnaire has users rank the extent the agree with each question with the total score range of 0 - 100; the lowest score indicating 0 - "Not at all" and the highest score indicating 100- "Totally".
Neuropathic Pain Scale (NPS) Up to 10 Weeks Neuropathic Pain Scale (NPS): This scale was developed to assess both the quantitative and qualitative qualities of neuropathic pain (NP). It includes 11 items, assessing global pain intensity, unpleasantness, and one item which allows the patient to describe the temporal aspects of their pain and its qualities in their own words.The remaining 8 items assess specific NP qualities: "Sharp," "Hot," "Dull," "Cold," "Sensitive," "Itchy," "Deep," and "Surface." This is a sensitive tool for measuring changes in neuropathic pain after a therapeutic intervention. Total score range for NPS is 0 - 100, higher scores indicate more severity.
