Identifying Body Awareness-related Brain Network Changes During Cognitive Multisensory Rehabilitation for Reduced Neuropathic Pain in People With Spinal Cord Injury
In Brief
A clinical study evaluating Cognitive Multisensory Therapy, Usual Care, and 3 other interventions for Spinal Cord Injuries and Neuropathic Pain. Completed, enrolled 58 participants across 1 site.
Detailed Summary
Many adults with spinal cord injury (SCI) suffer from long-term debilitating neuropathic pain. Available treatments, including opioids, are ineffective at eliminating this pain. Based on preliminary data from Dr Morse and from Dr Van de Winckel, we have demonstrated that brain areas that are important for body awareness and pain perception (parietal operculum, insula) have weaker brain connectivity in adults with spinal cord injury than in able-bodied healthy adults and that Cognitive Multisensory Rehabilitation (CMR) can restore these networks. This study uses a delayed treatment arm phase I randomized controlled trial (RCT) for adults with SCI and a comparison of baseline outcomes in adults with SCI vs able-bodied healthy adults to address two aims: AIM 1: Determine baseline differences in resting-state and task-based fMRI activation and connectivity in adults with SCI compared to able-bodied healthy controls. AIM 2: Identify changes in brain activation and connectivity, as well as behavioral outcomes in pain and body awareness in adults with SCI after CMR versus standard of care.

Timeline
Interventions
Cognitive multisensory rehabilitation (CMR) is a type of physical therapy that incorporates conscious perception of body positions and movements during (multi)sensory discrimination exercises. The treating therapists will give 40 minutes of discrimination exercises embedded in functional movements followed by 5 minutes of applying the learned strategies during activities of daily living. CMR uses several types of discrimination exercises: Participants discriminated shapes, length, weight, distance, resistance, textures or compare kinesthetic information with visual information for integration of multisensory information. Solving the discrimination task is combined with reflection and a learning process, prompted by the therapist on how the limb (was) moved or was positioned.
Standard of care treatment for neuropathic pain after spinal cord injury
Clinical assessments are detailed below. Screening will include demographic and general health data; mini mental state evaluation (MMSE)-short version; Edinburgh handedness inventory; and the kinesthetic and visual imagery questionnaire (KVIQ).
The MRI scanning will include structural scans, resting-state functional MRI, and 4 task-based functional MRI.
This part is OPTIONAL: 38ml of blood will be taken one time (for able body adults) or at 3 time points (for adults with spinal cord injury and neuropathic pain.
