Identifying Body Awareness-related Brain Network Changes During Cognitive Multisensory Rehabilitation for Reduced Neuropathic Pain in People With Spinal Cord Injury

April 12, 2024 updated by: University of Minnesota

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 cross-over study 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.

Detailed Description

One of the reasons for the current lack of effective therapies is that underlying mechanisms of neuropathic pain after SCI are not yet fully understood. Nonetheless, as suggested by numerous studies, because of the spinal injury, the inflow of sensory information is dramatically altered. Therefore, the brain is missing sensory information or receiving incorrect sensory information, which may alter the brain circuitry related to pain sensation, which in turn may drive the perception of neuropathic pain.

Cognitive multisensory rehabilitation (CMR), developed for motor recovery after stroke, has shown to be effective for treating adults with chronic pain, i.e., after shoulder impingement when compared to traditional physical therapy; or in a case study of severe phantom limb pain after below the knee amputation, resulting in such substantial pain reduction that the patient could finally be fitted with a prosthesis and walk. CMR is thought to be effective because it restores mental body representations by recalibrating sensations in combination with a focus on body awareness. Body awareness is often impaired in people with chronic pain and with dysfunctions in the sensory and motor networks, such as after SCI.

This study uses a cross-over study 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.

Participants in this arm will be able-bodied healthy adults who will not receive an intervention.

This is just a one time testing of clinical assessments (over zoom), one MRI scan, and an optional blood draw test.
Behavioral: Clinical Assessment
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).
Behavioral: Magnetic Resonance Imaging (MRI)
The MRI scanning will include structural scans, resting-state functional MRI, and 4 task-based functional MRI.
Other: OPTIONAL: blood draw
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.
Experimental: Usual Care, then Cognitive Multisensory Therapy - adults with spinal cord injury + neuropathic pain.
This is a cross-over study for participants with spinal cord injury and neuropathic pain. Participants in this arm will first receive usual care and then switch over to the experimental cognitive multisensory therapy training.

Behavioral: Cognitive Multisensory Therapy
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.

There are 9 items scored from 0 to 3 based on the frequency of occurrence of depression symptoms in the past two weeks, 0= not at all, 1=several days, 2=more than half the days, 3= nearly every day. Total score is a sum of all items scores and should be interpreted as follows:

5-9 Minimal Symptoms 10-14 Moderate depression 15-20 Moderately Severe depression >20 Severe depression

And a single question rates how difficult problems have made it to do work, take care of things at home or get along with other people, using a 4-level scale ranging from not difficult at all to externally difficult.

Patient Specific Functional Scale
Time Frame: baseline - mid evaluation (after 12 weeks) - final evaluation (after second period of 12 weeks)
The participants will self-identify goals related to activities in daily life that are important to them. The participants will rate them at each time point between 0 (i.e., unable to do the activity without pain) and 10 (able to do the activity without pain).This is a valid measure to assess disability in individuals with chronic pain.101 Time to administer: 5 minutes
