Abstract
RATIONALE Central neuropathic pain resulting from spinal cord injury is notoriously debilitating and difficult to treat with few currently available treatments. A novel molecule with intrathecal administration: Ziconotide has been approved for treatment of refractory neuropathic pain in general. It acts as a presynaptic calcium channel blocker. A pilot study has shown its potential in SCI neuropathic pain patients. OBJECTIVE The aim of this study is to determine the long-term (6 months) efficacy of chronic intrathecal ziconotide for the treatment of neuropathic SCI pain. STUDY DESIGN Multicenter, Randomized, Comparative, Placebo controlled, Double blind clinical trial, with a crossover of random alternated periods of 6 months (placebo or ITZ) for a total of 15 months including a total of 44 patients. STUDY POPULATION • Patients with SCI of various etiologies exhibiting neuropathic pain refractory to non-invasive treatments. • > 18 years. INTERVENTION Intrathecal administration of ziconotide via an implanted pump. STUDY OUTCOMES Primary study outcome Difference in pain intensity for all patients between effective treatment and placebo periods. Secondary study outcomes 1. Continuous evaluation of pain intensity. 2. Percentage of patients with at least 30% of pain reduction. 3. Satisfaction level of the patient pain relief. 4. Declarations of serious adverse events. 5. Duration and intensity of spontaneous and provoked pain. 6. Quality of life. 7. Patient global impression of change. 8. Quantification of daily dosages of analgesic drug intake. 9. Long term memory and neurocognitive effects. 10. Assessment of the patient's physical and emotional distress. NATURE AND EXTENT OF THE BURDEN AND RISKS ASSOCIATED WITH PARTICIPATION, BENEFIT, AND GROUP RELATEDNESS: Participation in this study is in accordance with current treatment protocols for SCI neuropathic pain in France therefore it proposes a treatment that would currently be considered regular practice even though no RCT evidence is yet available. The study gives patients the advantage of directly testing versus placebo a treatment that otherwise entails significant constraints. A Data Safety Monitoring board (DSMB) will be created for continuous safety analysis. Furthermore, patients will be followed in specialized pain centers offering the possibility of continuing their treatment after the study period.

Socio-ecological Barriers to Leisure Time Physical Activity in Spanish Wheelchair Users With Spinal Cord Injury: Associations With Sociodemographic Characteristics and Functional Independence. Arch Phys Med Rehabil 2024; 105:1239-1246. [PMID: 38417776 DOI: 10.1016/j.apmr.2024.02.719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 02/09/2024] [Accepted: 02/13/2024] [Indexed: 03/01/2024]
Abstract
OBJECTIVE (1) To assess prevalence and severity of socio-ecological barriers to leisure time physical activity (LTPA) in a sample of adults with spinal cord injury (SCI); (2) to examine the association of these barriers with sociodemographic characteristics and functional independence (FI); and (3) to explore which socio-ecological levels of barriers might be associated with LTPA. DESIGN Cross-sectional study. SETTING Neurorehabilitation Hospital specialized in SCI. PARTICIPANTS 207 wheelchair users with SCI living in the community who attended a comprehensive check-up (22.7% women, 47.5±10.7 mean age; N=207). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The short version of the Barriers to Physical Activity Questionnaire for People with Mobility Impairments was used to measure socio-ecological barriers to LTPA. The Spinal Cord Independence Measure III was used to measure FI. The Physical Activity Recall Assessment for People with SCI was used to quantify LTPA. Several multiple linear regression models were computed to examine the associations between socio-ecological barriers and sociodemographic factors, LTPA and FI. RESULTS A high prevalence of barriers to LTPA was found. Seven of these barriers (2 intrapersonal, 3 organizational, and 2 community) were present for >60% of the participants. Intrapersonal and organizational barriers had a higher effect on participants with lower FI and women. Interpersonal barriers were higher for older participants and with lower FI, while community barriers were higher for unemployed participants. Finally, intrapersonal and interpersonal barriers were negatively associated with LTPA, and FI revealed as a moderator of the intrapersonal barriers-LTPA relation. CONCLUSIONS Given their high prevalence and their association with LTPA, the development of interventions targeting socio-ecological barriers to LTPA in people with SCI becomes crucial. The associations of these barriers with FI and sociodemographic characteristics should also be considered for these interventions to be as specific and effective as possible.

Abstract
BACKGROUND In our published randomized controlled trial, we revealed that patients with acute ASIA Grade C incomplete cervical spinal cord injury (SCI) who underwent early surgery (within 24 h post-injury) had accelerated motor recovery at six months than those with delayed surgery (>2 weeks post-injury); however, neuropathic pain (NeP) worsened regardless of surgery timing. Here, we conducted post-hoc analyses to intensively assess NeP development and maintenance. METHODS Of 44 patients (median 64.5 years; three female; early intervention, n = 26), NeP was categorized into at-level and below-level pain and evaluated at two weeks and one year after injury using the Neuropathic Pain Symptom Inventory (NPSI). We compared the two groups based on background characteristics. A mixed-design analysis of variance with sex as a covariate was conducted to analyze motor recovery and Health-related quality of life (HRQOL) in groups with severe (NPSI ≥ 10) or mild (NPSI < 10) pain. RESULTS Upper and lower limb motor impairments were comparable between both groups regardless of pain severity. Severe at-level pain remained stable and worsened at one year than mild at-level pain; however, the upper- and lower-limb motor scores and HRQOL had comparable recovery. Background characteristics did not affect severity or time course of NeP. Patients with severe below-level pain demonstrated slower lower-limb motor recovery than those with mild below-level pain, whereas HRQOL improved regardless of pain severity. CONCLUSIONS Both at-level and below-level NeP developed and persisted relatively early in the course of traumatic SCI with incomplete motor paralysis; their severities worsened over time or remained severe since onset.

Abstract
OBJECTIVE To identify mediating roles of mindfulness, self-efficacy, social support, and functional independence in the relationship between pain and quality of life (QOL) in persons with spinal cord injury (SCI). METHODS A cross-sectional descriptive study was conducted using a sample of 272 persons with SCI living in the United States. The participants completed self-report standardized questionnaires on a Qualtrics survey. A parallel mediation analysis adjusting for covariates was performed to test the hypotheses. RESULTS Findings showed significant direct effects of pain on functional independence, self-efficacy, mindfulness, and social support. Self-efficacy, mindfulness, and social support had significant direct effects on QOL. In the mediation analysis, mindfulness, self-efficacy, and social support significantly mediated the relationship between pain and QOL, controlling for other variables in the model. CONCLUSIONS This study adds to the extant literature by providing evidence that mindfulness, self-efficacy, and social support not only directly contribute to QOL but are likely to mitigate the negative effect of pain on QOL in persons with SCI. Identifying these potential factors that can assuage the adverse effects of pain on QOL is a first step toward active intervention to facilitate the adjustment of persons with SCI.

Abstract
Background Pain after spinal cord injury (SCI) is debilitating and has been reported to be difficult to treat, despite pharmacological interventions. Pain medication misuse (PMM) and associated individual factors among people with spinal cord injury (PWSCI) are scarce. Aim To determine PMM and the associated factors in PWSCI. Setting Homes of community-dwelling manual wheelchair users with SCI in South Africa. Methods Community-dwelling PWSCI (n = 122) were consecutively sampled and the Pain Medication Questionnaire (PMQ) was used to determine PMM. Descriptive statistics, Fisher's exact test, independent t-tests, and simple linear regression tests were performed using SPSS v27. Testing was conducted at the 0.05 level of significance. Results Eighty-five per cent of the participants reported the presence of pain and 48.1% of them used pain medication. Forty-four percent of people who used pain medication scored ≥ 30, indicative of serious aberrant drug-taking behaviours. Opioids were mainly used for neuropathic pain and in combination with other types of medications such as anticonvulsants and non-steroidal anti-inflammatories (44.0%). Pain severity and the type of pain medication were found to be predictors of PMM (p < 0.01 respectively). Conclusion Pain relief after SCI remains difficult to achieve, with an evident high risk of PMM, which may lead to long-lasting side effects, dependency, or overdose. Contribution This study has shown the need for the assessment of the potential risk of dependency before prescribing pain medication, particularly opioids to PWSCI.

Abstract
In recent decade microglia have been found to have a central role in the development of chronic neuropathic pain after injury to the peripheral nervous system. It is widely accepted that peripheral nerve injury triggers microglial activation in the spinal cord, which contributes to heightened pain sensation and eventually chronic pain states. The contribution of microglia to chronic pain arising after injury to the central nervous system, such as spinal cord injury (SCI), has been less studied, but there is evidence supporting microglial contribution to central neuropathic pain. In this systematic review, we focused on post-SCI microglial activation and how it is linked to emergence and maintenance of chronic neuropathic pain arising after SCI. We found that the number of studies using animal SCI models addressing microglial activity is still small, compared with the ones using peripheral nerve injury models. We have collected 20 studies for full inclusion in this review. Many mechanisms and cellular interactions are yet to be fully understood, although several studies report an increase of density and activity of microglia in the spinal cord, both in the vicinity of the injury and in the spared spinal tissue, as well as in the brain. Changes in microglial activity come with several molecular changes, including expression of receptors and activation of signalling pathways. As with peripheral neuropathic pain, microglia seem to be important players and might become a therapeutic target in the future.

Abstract
Our goal was to test the effectiveness of collaborative care (CC) versus usual care (UC) to improve treatment of pain, depression, physical inactivity, and quality of life in outpatients with spinal cord injury (SCI). We conducted a single blind parallel group randomized controlled trial. The setting was two outpatient SCI rehabilitation clinics within a large academic medical center. Participants were 174 outpatients who were on average 47.7 years old, 76% male, 76% white, 8% Hispanic, 47% tetraplegic, 95% more than 1 year post-SCI, and 45% on Medicare. The intervention consisted of a mental health-trained collaborative care manager (CM) integrated into two SCI rehabilitation medicine clinics and supervised by content experts in pain and mental health treatment. The CM provided assessment, medical care coordination, adherence support, outcome monitoring, and decision support along with brief psychological interventions to the patients via up to 12 in-person or telephone sessions. Among all participants, 61% chose to focus on pain; 31% on physical activity and 8% on depression. The primary outcome was quality of life as measured by the World Health Organization Quality of Life-BREF at the end of treatment (4 months). Secondary outcomes were quality of life at 8 months and pain intensity and interference, depression severity, and minutes per week of moderate to vigorous physical activity at 4 and 8 months. A total of 174 participants were randomized 1:1 to CC (n = 89) versus UC (n = 85). The primary analysis, a mixed-effects linear regression adjusting for time since injury and sex, revealed a non-significant trend for greater improvement in quality of life in CC versus UC at 4 months (p = 0.083). Secondary analyses showed that those receiving CC reported significantly greater improvement in pain interference at 4- and 8-months and in depression at 4-months, but no significant effect on physical activity. We conclude that in an outpatient SCI care setting, CC is a promising model for delivering integrated medical and psychological care and improving management of common, chronic, disabling conditions such and pain and depression.

Abstract
OBJECTIVE To examine change in pain interference and depression over a 10-year time period in individuals with long-term traumatic spinal cord injury (SCI) and to identify the extent to which changes in pain interference over time predicts change in depressive symptoms. DESIGN Longitudinal analyses of self-report assessment data. SETTING Specialty and university hospitals in the Southeastern and Midwestern United States. PARTICIPANTS Adults with a history of traumatic SCI (n = 504) who responded to the three most recent data collection periods of the SCI Longitudinal Aging Study (2008 [Time 1], 2013 [Time 2], and 2018 [Time 3]). The participants averaged 59 years of age and 32 years since injury onset at Time 3. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Patient Health Questionnaire (PHQ-9) assessed depressive symptom severity. The 7-item Pain Interference scale from the Brief Pain Inventory assessed pain interference. RESULTS Over the three study timepoints, the sample averaged moderate levels of pain interference and mild depressive symptom severity. Unconditional linear growth models, reflecting changes in central tendency, indicated that pain interference significantly decreased and depressive symptom severity significantly increased over time. Multiple independent variables random coefficient modeling based on correlations suggested that change in pain interference was positively associated with change in depressive symptom severity over the 10-year study follow-up. CONCLUSION Average depressive symptom severity worsened over time. Change in pain interference was positively associated with change in depressive symptom severity. These results point to the complexity of aging related changes in depressive symptoms and pain interference. They further support the need for continued assessment of mood and pain experiences, particularly among individuals reaching aging milestones with SCI.

Abstract
OBJECTIVES To evaluate the clinical characteristics, hospital courses, outcomes after hospitalization, and factors associated with outcomes in patients with nontraumatic spinal cord injuries (NTSCI). DESIGN Retrospective analysis. SETTING A large for-profit United States health care system. PARTICIPANTS 2807 inpatients with NTSCI between 2014 and 2020 were identified using International Classification of Disease codes. MAIN OUTCOME MEASURE Demographic, clinical characteristics, hospital course, and disposition data collected from electronic health record. RESULTS The mean age was 57.91 ± 16.41 years with 69.83% being male. Incomplete cervical level injury was the most common injury type, spinal stenosis was the most common diagnostic etiology and central cord syndrome was the most common clinical syndrome. The average length of stay was 9.52 ± 15.8 days, with the subgroup of 1308 (46.6%) patients who were discharged home demonstrating a shorter length of stay (6.42 ± 10.24 days). Falls were the most common hospital-acquired complication (n = 424, 15.11%) and 83 patients deceased. There were increased odds of non-home discharge among patients with the following characteristics: older age, Medicare insurance, non-black racial minority, increased Charlson Comorbidity Index (CCI), intensive care unit (ICU) stay, use of steroid or anticoagulant medications, and hospital-acquired pulmonary complications. Increased in-hospital mortality was observed in those with Medicaid insurance, ICU stay, increased CCI, diagnosis of degenerative spine disease, other unspecified level of injury, and hospital-acquired pulmonary complications. CONCLUSIONS NTSCI in this sample were predominantly incomplete cervical central SCIs. Increased CCI, ICU stay, and hospital-acquired pulmonary complications were associated with poorer outcomes after acute care hospitalization among patients with NTSCI.

Abstract
Chronic pain is a very common problem in patients with spinal cord injury (SCI) as it affects 80% of these patients, which negatively affects their quality of life. Despite many advantages that exist in the management of any type of pain (neuropathic, nociceptive, mixed) in these patients, there is no cure, and the analgesic effect of some treatments is inadequate. This study aims to conduct an evidence-based systematic review regarding the various interventions used for the management of pain after SCI. The PubMed, Physiotherapy Evidence Database (PEDro), and Cochrane Library databases were searched from 1969 to 2023. The risk of bias was assessed using the PEDro scoring system. A total of 57 studies met the inclusion criteria and were included in this systematic review. Among the different interventions at present, 18 studies examined the role of oral medications, 11 studies examined the role of minimally invasive methods (injection and infusion), 16 studies investigated physiotherapy and alternative treatments, and 12 studies examined the role of repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS), and cranial electrotherapy stimulation (CES) in the management of pain in patients after SCI. Gabapentin and pregabalin are very effective in managing chronic neuropathic pain after SCI, and pregabalin also seems to reduce anxiety and sleep disturbances in the patients. It is noteworthy that lamotrigine, valproate, and carbamazepine do not have an analgesic effect, but mirogabalin is a novel and promising drug. Antidepressants (selective serotonin reuptake inhibitors and serotonin and noradrenaline reuptake inhibitors) did not reduce the pain of the patients, although some studies showed an efficacy of amitriptyline especially in depressed patients and tramadol should be considered short-term with caution. Also, tDCS and rTMS reduced pain. Moreover, botulinum toxin type A, lidocaine, ketamine, and intrathecal baclofen significantly reduced pain intensity, although the sample of the studies was small. Physiotherapy and alternative treatments seem to relieve pain, and transcutaneous electrical nerve stimulation had the greatest reduction of pain intensity. In conclusion, several pharmaceutical and non-pharmaceutical methods exist, which can reduce pain in patients after SCI. The type of intervention can be considered by the physician depending on the patients' preference, age, medical history, type of pain, and associated symptoms. However, more studies with greater samples and with better methodological quality should be conducted.

Abstract
OBJECTIVE To examine risk factors related to death by suicide among installation, maintenance, and repair (IMR) workers compared with workers in other occupational groups. METHODS The National Violent Death Reporting System (NVDRS) data for the years 2013 to 2018 was used to identify suicide deaths. Circumstance variables were used to examine differences between IMR workers and other workers. RESULTS Having a physical health problem (1.13; 95% confidence interval [CI], 1.03 to 1.23) or a diagnosis of posttraumatic stress disorder (1.24; 95% CI, 1.03 to 1.50) was more likely to contribute to IMR worker suicide compared with other occupations. Installation, maintenance, and repair workers were less likely to receive treatment for a mental health diagnosis or substance use disorder (0.88; 95% CI, 0.81 to 0.94). CONCLUSIONS Additional support for physical health problems, posttraumatic stress disorder diagnoses, and mental health care access among IMR workers may reduce suicide deaths.

Abstract
BACKGROUND The incidence of spinal cord injury is increasing worldwide. Patients with spinal cord injury and their families face many difficulties during the disease course. Caregivers are more involved with these patients than anyone else, so recognizing patients' care requirements based on caregivers' opinions can facilitate care provision to these people. The purpose of this study was to explore caregivers' perceptions of the community-based services requirements of patients with spinal cord injury. METHODS This qualitative research was conducted in Iran from Apr 2021 to Dec 2022 using the conventional content analysis method. The participants in the study included family caregivers and providers of home care services to patients with spinal cord injury, who were selected by purposeful sampling. Data were collected by conducting 14 face-to-face interviews and analyzed based on the method proposed by Lundman and Graneheim. RESULTS Data analysis led to the extraction of 815 primary codes, which were organized into two themes: community reintegration (with two categories, including the need to provide a suitable social platform and lifelong care) and palliative care (with two categories, including family conference and survival management). CONCLUSION Social facilities and infrastructure should be modified in a way that patients with spinal cord injury can appropriately benefit from community-based care services and an independent satisfactory life. Palliative care should be continuously provided from the time of lesion development until the patient's death.

Abstract
PURPOSE To evaluate how Canadian clinicians involved in trauma patient care and prescribing opioids perceive the use and effectiveness of strategies to prevent long-term opioid therapy following trauma. Barriers and facilitators to the implementation of these strategies were also assessed. METHODS We conducted a web-based cross-sectional survey. Potential participants were identified by trauma program managers and directors of the targeted departments in three Canadian provinces. We designed our questionnaire using standard health survey research methods. The questionnaire was administered between April 2021 and November 2021. RESULTS Our response rate was 47% (350/744), and 52% (181/350) of participants completed the entire survey. Most respondents (71%, 129/181) worked in teaching hospitals. Multimodal analgesia (93%, 240/257), nonsteroidal anti-inflammatory agents (77%, 198/257), and physical stimulation (75%, 193/257) were the strategies perceived to be the most frequently used. Several preventive strategies were perceived to be very effective by over 80% of respondents. Of these, some that were reported as not being frequently used were perceived to be among the most effective ones, including guidelines or protocols, assessing risk factors for opioid misuse, physical health follow-up by a professional, training for clinicians, patient education, and prescription monitoring systems. Staff shortages, time constraints, and organizational practices were identified as the main barriers to the implementation of the highest ranked preventive strategies. CONCLUSIONS Several strategies to prevent long-term opioid therapy following trauma are perceived as being effective by those prescribing opioids in this population. Some of these strategies appear to be commonly used in everyday practice and others less so. Future research should focus on which preventive strategies should be given higher priority for implementation before assessing their effectiveness.

Abstract
More than half of spinal cord injury (SCI) patients develop central neuropathic pain (CNP), which is largely refractory to current treatments. Considering the preclinical evidence showing that polyphenolic compounds may exert antinociceptive effects, the present work aimed to study preventive effects on SCI-induced CNP development by repeated administration of two vegetal polyphenolic extracts: grape stalk extract (GSE) and coffee extract (CE). Thermal hyperalgesia and mechanical allodynia were evaluated at 7, 14 and 21 days postinjury. Then, gliosis, ERK phosphorylation and the expression of CCL2 and CX3CL1 chemokines and their receptors, CCR2 and CX3CR1, were analyzed in the spinal cord. Gliosis and CX3CL1/CX3CR1 expression were also analyzed in the anterior cingulate cortex (ACC) and periaqueductal gray matter (PAG) since they are supraspinal structures involved in pain perception and modulation. GSE and CE treatments modulated pain behaviors accompanied by reduced gliosis in the spinal cord and both treatments modulated neuron-glia crosstalk-related biomolecules expression. Moreover, both extracts attenuated astrogliosis in the ACC and PAG as well as microgliosis in the ACC with an increased M2 subpopulation of microglial cells in the PAG. Finally, GSE and CE prevented CX3CL1/CX3CR1 upregulation in the PAG, and modulated their expression in ACC. These findings suggest that repeated administrations of either GSE or CE after SCI may be suitable pharmacologic strategies to attenuate SCI-induced CNP development by means of spinal and supraspinal neuroinflammation modulation.

Abstract
Spinal cord injury (SCI) is a complex syndrome that has profound effects on patient well-being, including the development of medically-resistant chronic pain. The mechanisms underlying SCI pain have been the subject of thorough investigation but remain poorly understood. While the majority of the research has focused on changes occurring within and surrounding the site of injury in the spinal cord, there is now a consensus that alterations within the peripheral nervous system, namely sensitization of nociceptors, contribute to the development and maintenance of chronic SCI pain. Using an ex vivo skin/nerve/DRG/spinal cord preparation to characterize afferent response properties following SCI, we found that SCI increased mechanical and thermal responding, as well as the incidence of spontaneous activity (SA) and afterdischarge (AD), in below-level C-fiber nociceptors 24 hr following injury relative to naïve controls. Interestingly, the distribution of nociceptors that exhibit SA and AD are not identical, and the development of SA was observed more frequently in nociceptors with low heat thresholds, while AD was found more frequently in nociceptors with high heat thresholds. We also found that SCI resulted in hindpaw edema and elevated cutaneous calcitonin gene-related peptide (CGRP) concentration that were not observed in naïve mice. These results suggest that SCI causes a rapidly developing nociceptor sensitization and peripheral inflammation that may contribute to the early emergence and persistence of chronic SCI pain.

Abstract
OBJECTIVE To assess the feasibility and potential benefits of clinical meditation and imagery (CMI) for people with chronic spinal cord injury (SCI) and chronic pain. DESIGN Pilot randomized, controlled trial. SETTING Outpatients with SCI in the United States. PARTICIPANTS 24 adults with chronic SCI (>1 year) and a >3 month history of pain rated ≥4/10 on average over the last week. INTERVENTIONS 4-week program of once-weekly 2-hour group classes, offered in-person and online. CMI group participants were taught mindfulness, mantra meditation, and guided imagery practices. Control group participants received education on topics related to health and function after SCI. OUTCOME MEASURES Pain interference (primary outcome), pain cognitions, pain intensity/unpleasantness, depressive symptomology, perceived stress. RESULTS Pain interference decreased to a greater extent in the control group at both Day 42 and Day 70, with a large effect size (d > 1.0). Several secondary outcome measures showed changes consistent with more favorable outcomes in the CMI group at both Day 42 and Day 70, with a large effect size d > 0.80, including worst pain intensity over the last week, depressive symptomology, belief in pain as a sign of harm and perceived control over pain. Perceived stress improved to a greater extent in the control group (d = 1.16 at Day 42, d = .20 at Day 70). CONCLUSION CMI is feasible and acceptable to implement with people with SCI and chronic pain. Further study is warranted to assess potential benefits for pain-related outcomes.

Abstract
In addition to helping individuals with spinal cord injury (SCI) regain the ability to ambulate, the rapidly evolving capabilities of robotic exoskeletons provide an array of secondary biophysical benefits which can reduce the complications resulting from prolonged immobilization. The proposed benefits of increased life-long over-ground walking capacity include improved upper body muscular fitness, improved circulatory response, improved bowel movement regularity, and reduced pain and spasticity. Beyond the positive changes related to physical and biological function, exoskeletons have been suggested to improve SCI individuals' quality of life (QOL) by allowing increased participation in day-to-day activities. Most of the currently available studies that have reported on the impact of exoskeletons on the QOL and prevention of secondary health complications on individuals with SCI, are of small scale and are heterogeneous in nature. Moreover, few meta-analyses and reviews have attempted to consolidate the dispersed data to reach more definitive conclusions of the effects of exoskeleton use. This scoping review seeks to provide an overview on the known effects of overground exoskeleton use, on the prevention of secondary health complications, changes to the QOL, and their effect on the independence of SCI individuals in the community settings. Moreover, the intent of the review is to identify gaps in the literature currently available, and to make recommendations on focus study areas and methods for future investigations.

Abstract
STUDY DESIGN Case-control study. OBJECTIVES To identify factors associated with neuropathic pain (NP) in patients with spinal cord injury of traumatic origin (TSCI). SETTING University Hospital of Valle, Cali, Colombia. METHODS Study participants were individuals with diagnosis of TSCI who visited a trauma referral center from January 1st, 2016, to December 31st, 2016. Information was retrospectively extracted from the Hospital's Spinal Cord Injury registry and patients' medical records. Cases were defined as patients with NP and controls were those without NP. The exposure of interest was intentional injuries. Individuals were matched by age and stratified into 11 groups of ±3 years each. RESULTS We found 164 participants with an average age of 34 ± 13 years, of whom 95.1% were male, and 53.6% had NP. Neurogenic bladder and bowel occurred in 94.3% of NP patients. Cause of injury was not associated with NP. Older injuries were protective for NP (>10 years since injury OR = 0.10, 95% CI = 0.03-0.37, p < 0.0001) and neurogenic bladder and bowel were found as risk factors (OR = 5.89, 95% CI = 1.84-18.88; p = 0.003). CONCLUSIONS Our study uniquely shows time since injury as a protective factor for NP and neurogenic bladder and bowel as a risk factor, while violence was not found associated. This could help guide the scope of future research about NP secondary to SCI.

Abstract
Endowed with inherent flexibility, wearable robotic technologies are powerful devices that are known to extend bodily functionality to assist people with spinal cord injuries (SCIs). However, rather than considering the specific psychological and other physiological needs of their users, these devices are specifically designed to compensate for motor impairment. This could partially explain why they still cannot be adopted as an everyday solution, as only a small number of patients use lower-limb exoskeletons. It remains uncertain how these devices can be appropriately embedded in mental representations of the body. From this perspective, we aimed to highlight the homeostatic role of autonomic and interoceptive signals and their possible integration in a personalized experience of exoskeleton overground walking. To ensure personalized user-centered robotic technologies, optimal robotic devices should be designed and adjusted according to the patient's condition. We discuss how embodied approaches could emerge as a means of overcoming the hesitancy toward wearable robots.

Abstract
Purpose: Spinal cord injury-related pain is often a severe debilitating condition that adversely affects the patient's physical health, psychological wellbeing and quality of life. Opioid medications have historically been prescribed to this population with great frequency. As opioid abuse disorder becomes an ever-worsening public health issue, more attention must be placed upon non-opioid options. This paper reviews non-opioid medications to be considered when treating spinal cord injury-related pain. The pertinent literature is reviewed, and the advantages and pitfalls of various medication options are discussed in the complicated context of the individual with a spinal cord injury.Methods: Peer-reviewed journal articles and medication package insert data are reviewed.Results:. The non-opioid medications with the greatest evidence for efficacy in the treatment of chronic spinal cord injury-related pain are drawn from the antiepileptic drug and antidepressant categories though the specific selection must be nuanced to the particular individual patient. More research is required to understand the role of calcitonin, lithium, and marijuana in treating spinal cord injury-related pain.Conclusions: The complex clinical situation of each individual patient must be weighed against the risks and benefits of each medication, as reviewed in this paper, to determine the ideal treatment strategy for chronic spinal cord injury-related pain.

Abstract
Background Pain after spinal cord injury (SCI) is common and is likely to continue throughout life with varying levels of severity. Objective To determine the presence of pain, the sociodemographic and injury profile of community-dwelling manual wheelchair users. Method This quantitative correlational study used a sociodemographic and injury profile sheet and the Douleur Neuropathique 4 Questions (DN4) questionnaire to document demographic, SCI profiles as well as pain characteristics. Pain severity was determined using the Numeric Rating Scale. Data were analysed using the Statistical Package for the Social Sciences (SPSS) v27 at 0.05 level of significance. Results The pain rate was 104; 85% of 122 participants and mainly in those with complete SCI (77.9%). Neuropathic pain was more common (76; 62.5%) and significantly associated (p < 0.05) with higher pain severity. Pain was mainly in one area of the body (59; 48.4%) but occurring in up to five areas. The most painful area had a mean severity of 6.7/10; was more common in the lower limbs below the injury level (48; 39.4%); and was burning in nature (40; 32.7%). Conclusions Pain after SCI is as problematic in the South African context as it is globally. With the rising SCI prevalence in the country, understanding pain and its presentation is important for holistic management of a person with SCI. Clinical implications In-depth assessment of pain should be conducted and appropriate management interventions for specific pain types be prescribed to effectively reduce pain.

Abstract
ABSTRACT Chronic neuropathic pain (NP) is a common and often debilitating secondary condition for persons with spinal cord injury (SCI) and is minimally responsive to existing pharmacological and nonpharmacological treatments. The current preliminary investigation describes the feasibility and initial comparative efficacy of an interactive virtual reality walking intervention, which is a novel extension of visual feedback/illusory walking therapies shown to reduce SCI NP. Virtual reality walking intervention builds on previous research by, for the first time, allowing individuals with SCI NP to volitionally control virtual gait to interact with a fully immersive virtual environment. The current pilot study compared this interactive, virtual walking intervention to a passive, noninteractive virtual walking condition (analogous to previous illusory walking interventions) in 27 individuals with complete paraplegia (interactive condition, n = 17; passive condition, n = 10; nonrandomized design). The intervention was delivered over 2 weeks in individuals' homes. Participants in the interactive condition endorsed significantly greater reductions in NP intensity and NP-related activity interference preintervention to postintervention. Notable improvements in mood and affect were also observed both within individual sessions and in response to the full intervention. These results, although preliminary, highlight the potentially potent effects of an interactive virtual walking intervention for SCI NP. The current study results require replication in a larger, randomized clinical trial and may form a valuable basis for future inquiry regarding the mechanisms and clinical applications of virtual walking therapies.

Abstract
STUDY DESIGN Survey OBJECTIVES: Better understand the demographics of pain after spinal cord injury (SCI). SETTING Academic Level 1 trauma center and SCI Model System. METHODS A survey including general demographic questions, questions of specific interest to the authors, the standardized SCI Pain Instrument (SCIPI), International SCI Pain Data Set, Basic form (ISCIPDS:B), Patient Reported Outcomes Measurement Information System (PROMIS) neuropathic 5a (PROMIS-Neur), and PROMIS nociceptive 5a (PROMIS-No). RESULTS 81% of individuals with SCI experience chronic pain and 86% of individuals with pain have neuropathic pain. 55% of individuals had shoulder pain. Females and those who recall >5/10 pain during initial hospital stay had significantly higher PROMIS-Neur scores. Completeness of injury correlates inversely with the degree of neuropathic pain. Those who recall >5 pain during the initial hospital stay and those who reported the worst or second worst pain as being shoulder pain had significantly higher PROMIS-No scores. Lumbosacral injuries trended towards higher PROMIS-No scores and had the highest PROMIS-Neur scores. Those with tetraplegia were more likely to develop shoulder pain and those with shoulder pain had higher PROMIS-No scores. CONCLUSIONS Chronic pain is almost universal in patients with SCI. Pain is more commonly reported as neuropathic in nature and females reported more neuropathic pain than males. Physicians should monitor for nociceptive shoulder pain, particularly in those with tetraplegia. Patients with incomplete injuries or lumbosacral injuries are more likely to report higher levels of neuropathic pain and pain levels should be monitored closely. Those with more neuropathic and nociceptive pain recall worse pain at initial hospitalization. Better understanding pain demographics in this population help screen, prevent and manage chronic pain in these patients.

Abstract
Objectives: Tract-based spatial statistics (TBSS) is a diffusion tensor imaging (DTI)-based processing technique that aims to improve the objectivity and interpretability of analysis of multisubject diffusion imaging studies. This study used TBSS to measure quantitative changes in brain white matter structures following spinal cord injury (SCI). Methods: Eighteen SCI subjects aged 8-20 years old (mean age, 16.5 years) were scanned using a conventional single-shot EPI DTI protocol using a 3.0T Siemens MR scanner. All participants underwent a complete International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) examination to determine the level and severity of injury. Five participants were classified as American Spinal Injury Association Impairment Scale (AIS) A, nine as AIS B, and four as AIS C/D. Imaging parameters used for data collection were as follows: 20 directions, b = 1000 s/mm2, voxel size = 1.8 mm x 1.8 mm, slice thickness = 5 mm, TE = 95 ms, TR = 4300 ms, slices = 30, TA = 4:45 min. To generate TBSS, nonparametric permutation tests were used for voxel-wise statistical analysis of the fractional anisotropy (FA) skeletons between AIS groups. A two-tailed t test was applied to extract voxels with significant differences at p < .05. Results: Notable significant changes occurred throughout the corticospinal, spinothalamic, and dorsal column/medial lemniscus tracts. Altered regions in the temporal, occipital, and parietal lobes were also identified. Conclusion: These results suggest that white matter structures are altered differently between people with different AIS classifications. TBSS has the potential to serve as a screening tool to identify white matter changes in regions of interest.

Abstract
OBJECTIVE Secondary health conditions (SHCs) are long-term complications that frequently occur due to traumatic spinal cord injury (tSCI) and can negatively affect quality of life in this patient population. This study provides an overview of the associations between the severity and level of injury and the occurrence of SHCs in tSCI. METHODS A systematic search was conducted in PubMed and Embase that retrieved 44 studies on the influence of severity and/or level of injury on the occurrence of SHCs in the subacute and chronic phase of tSCI (from 3 months after trauma). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. RESULTS In the majority of studies, patients with motor-complete tSCI (American Spinal Injury Association [ASIA] Impairment Scale [AIS] grade A or B) had a significantly increased occurrence of SHCs in comparison to patients with motor-incomplete tSCI (AIS grade C or D), such as respiratory and urogenital complications, musculoskeletal disorders, pressure ulcers, and autonomic dysreflexia. In contrast, an increased prevalence of pain was seen in patients with motor-incomplete injuries. In addition, higher rates of pulmonary infections, spasticity, and autonomic dysreflexia were observed in patients with tetraplegia. Patients with paraplegia more commonly suffered from hypertension, venous thromboembolism, and pain. CONCLUSIONS This review suggests that patients with a motor-complete tSCI have an increased risk of developing SHCs during the subacute and chronic stage of tSCI in comparison with patients with motor-incomplete tSCI. Future studies should examine whether systematic monitoring during rehabilitation and the subacute and chronic phase in patients with motor-complete tSCI could lead to early detection and potential prevention of SHCs in this population.

Abstract
BACKGROUND Chronic opioid use has been documented in up to 20% of patients with traumatic injuries. Hence, we developed the Tapering Opioids Prescription Program for high-risk Trauma (TOPP-Trauma) patients. AIMS To assess the feasibility and acceptability of TOPP-Trauma, examine the feasibility of the research methods, and describe its potential efficacy in reducing long-term opioid use. DESIGN A two-arm pilot randomized controlled trial. METHODS Fifty participants discharged home were assigned to TOPP-Trauma or an educational pamphlet. Feasibility was assessed based on ability to provide the program components. The acceptability was assessed with the Treatment Acceptability and Preference Questionnaire. The feasibility of the research methods was evaluated according to standard parameters. Self-reported morphine equivalent dose (MED) and MEDs supplied by pharmacies were measured at 6 and 12 weeks. RESULTS Eighty percent or more of TOPP-Trauma components were delivered as planned, and the program was deemed highly acceptable. Approximately 10% of screened patients were eligible. Eighty-five percent of eligible patients agreed to participate with 20% attrition rates. TOPP-Trauma participants used less MED/day compared to the control group at 6 and 12 weeks (1.2. vs. 12.2 mg; 0.4. vs 4.0 mg), and pharmacies supplied less than half of cumulative MEDs to those who received the program at 12 weeks, but the differences were not statistically significant. CONCLUSIONS Some challenges need to be addressed before testing TOPP-Trauma. These include creating strategies to decrease attrition, offering the program throughout the care continuum to higher risk patients, and evaluating the impacts of reduced opioid use.

Abstract
OBJECTIVE Compare prevalence, intensity ratings, and interference ratings of neuropathic pain (NeuP) and nociceptive pain in people with chronic spinal cord injury (SCI) DESIGN: Cross-sectional survey SETTING: Six SCI Model System centers in the US PARTICIPANTS: Convenience sample of 391 individuals with traumatic SCI, aged 18 years or older, 81% male, 57% white INTERVENTIONS: Not applicable MAIN OUTCOME MEASURES: Survey based on the International Spinal Cord Injury Pain Basic Data Set (ISCIPBDS) and the Spinal Cord Injury Pain Instrument (SCIPI), including 0-10 numerical ratings of pain intensity and pain interference with daily activities, mood, and sleep RESULTS: 80% of those surveyed reported having at least one pain problem; 58% reported two or more pain problems; 56% had probable NeuP; and 49% had non-NeuP. When comparing ratings for all pains (n=354 for NeuP, n=290 for non-NeuP) across subjects, probable NeuPs were significantly more intense (6.9 vs. 5.7) and interfered more with activities (5.2 vs. 3.7), mood (4.9 vs. 3.2), and sleep (5.4 vs. 3.6) than non-NeuPs (all p<0.001). However, when comparing ratings for probable NeuPs and non-NeuPs within subjects, for the subgroup of 94 participants with both pain types, only ratings for sleep interference were found to be significantly different between the pain types . Additionally, we found significantly greater prevalence of NeuP and non-NeuP for women compared to men, and of NeuP for those with paraplegia compared to those with tetraplegia. CONCLUSIONS Independent assessment of the pain conditions experienced by an individual with SCI is useful in understanding the differential impact that pain type has on quality of life. This is particularly important with regard to sleep interference and should be kept in mind when determining treatment strategies for meeting patient-centered outcome goals.

Abstract
Objective: The majority of individuals with spinal cord injury (SCI) experience chronic pain. Chronic pain can be difficult to manage because of variability in the underlying pain mechanisms. More insight regarding the relationship between pain and physical activity (PA) is necessary to understand pain responses during PA. The objective of this study is to explore possible relationships between PA levels and secondary conditions including pain and fatigue.Design: Prospective cohort analysis of a pilot study.Setting: Community.Participants: Twenty individuals with SCI took part in the study, and sixteen completed the study.Interventions: Mobile-health (mHealth) based PA intervention for two-months during the three-month study.Outcome measures: Chronic Pain Grade Scale (CPGS) questionnaire, The Wheelchair User's Shoulder Pain Index (WUSPI), Fatigue Severity Scale (FSS), and PA levels measured by the mHealth system.Results: A positive linear relationship was found between light-intensity PA and task-specific pain. However, the relationship between moderate-intensity PA and pain interference was best represented by a curvilinear relationship (polynomial regression of second order). Light-intensity PA showed positive, linear correlation with fatigue at baseline. Moderate-intensity PA was not associated with fatigue during any phase of the study.Conclusion: Our results indicated that PA was associated with chronic pain, and the relationship differed based on intensity and amount of PA performed. Further research is necessary to refine PA recommendations for individuals with SCI who experience chronic pain.Trial registration: ClinicalTrials.gov identifier: NCT03773692.

Abstract
OBJECTIVE To evaluate whether pain interference mediates the relationship between pain intensity and probable major depression (PMD) among persons with spinal cord injury (SCI), accounting for differences in the frequency of prescription medication use and resilience. DESIGN Cross-sectional analysis using self-report assessment. SETTING Medical university in the Southeastern United States. PARTICIPANTS There were a total of 4670 participants (N=4670), all of whom had traumatic SCI of at least 1-year duration, identified from the Southeastern Regional SCI Model System and 2 state-based surveillance systems. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The Patient Health Questionnaire-9 was used to define PMD. Covariates included demographic and injury characteristics, pain severity, pain interference, and resilience. Separate sets of multistage logistic regression analyses were conducted for 3 levels of prescription pain medication use (daily, occasional/weekly, none). RESULTS Pain intensity was related to a greater risk of PMD (odds ratio [OR]daily pain medication user, 1.28; 95% confidence interval [CI], 1.21-1.35; ORoccasional/weekly pain medication user, 1.26; 95% CI, 1.16-1.36; ORnonpain medication user, 1.44; 95% CI, 1.33-1.56), but this relationship disappeared after consideration of pain interference (ORdaily pain medication user, 0.97; 95% CI, 0.90-1.04; ORoccasional/weekly pain medication user, 0.94; 95% CI, 0.84-1.05; ORnonpain medication user, 1.07; 95% CI, 0.95-1.20), which indicates pain interference was a mediator between pain intensity and PMD and there was no direct relationship between pain intensity and PMD. Resilience was protective of PMD in each model but was not a mediator. CONCLUSIONS Although pain intensity was associated with PMD, the relationship was mediated by pain interference. Resilience was an important protective factor. Therefore, clinicians should assess pain interference when screening for PMD and direct treatment at reducing pain interference. Building resilience may further reduce the risk of PMD.

Treatments that are perceived to be helpful for non-neuropathic pain after traumatic spinal cord injury: a multicenter cross-sectional survey. Spinal Cord 2021; 59:520-528. [PMID: 33742116 DOI: 10.1038/s41393-021-00621-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 02/23/2021] [Accepted: 02/26/2021] [Indexed: 12/19/2022]
Abstract
STUDY DESIGN Cross-sectional survey. OBJECTIVES The objective of the study was to identify the treatments that people with traumatic spinal cord injury (SCI) used for their non-neuropathic pains (nonNeuPs) and how they subjectively rated the helpfulness of those treatments. SETTING Six centers from the Spinal Cord Injury Model Systems. METHODS Three hundred ninety one individuals who were at least 1-year post-traumatic SCI were enrolled. A telephone survey was conducted for pharmacologic and non-pharmacologic treatments utilized in the last 12 months for each participant's three worst pains and the perceived helpfulness of each treatment for each pain. RESULTS One hundred ninety (49%) participants reported at least one nonNeuP (Spinal Cord Injury Pain Instrument score < 2) in the previous 7 days. NSAIDs/aspirin, acetaminophen, opioids, and cannabinoids were the most commonly used and helpful pharmacologic treatments for overall nonNeuP locations (helpful in 77-89% of treated pains). Body position adjustment, passive exercise, massage, resistive exercise, and heat therapy were reported as the most commonly used non-pharmacological treatments for nonNeuPs. Heat therapy, aerobic exercise, massage, and body position adjustment were the most helpful non-pharmacological treatments for overall nonNeuP locations (helpful in 71-80% of treated pains). Perceived helpfulness of treatments varied by pain locations, which may be due to different mechanisms underlying pains in different locations. CONCLUSIONS Results of the study may help guide clinicians in selecting pain-specific treatments for nonNeuPs. The self-reported helpfulness of heat therapy, exercise, and massage suggests a possible direction for clinical trials investigating these treatments of nonNeuP while limiting the side effects accompanying pharmacologic treatments.

Abstract
Spinal cord injury (SCI) affects an estimated three million persons worldwide, with ∼180,000 new cases reported each year leading to severe motor and sensory functional impairments that affect personal and social behaviors. To date, no effective treatment has been made available to promote neurological recovery after SCI. Deficits in motor function is the most visible consequence of SCI; however, other secondary complications produce a significant impact on the welfare of patients with SCI. Spasticity is a neurological impairment that affects the control of muscle tone as a consequence of an insult, trauma, or injury to the central nervous system, such as SCI. The management of spasticity can be achieved through the combination of both nonpharmacological and pharmacological approaches. Baclofen is the most effective drug for spasticity treatment, and it can be administered both orally and intrathecally, depending on spasticity location and severity. Interestingly, recent data are revealing that baclofen can also play a role in neuroprotection after SCI. This new function of baclofen in the SCI scope is promising for the prospect of developing new pharmacological strategies to promote functional recovery in patients with SCI.

Abstract
STUDY DESIGN Cross-sectional. OBJECTIVES To examine the association between post-traumatic stress disorder (PTSD) symptoms and pain intensity, taking symptoms of anxiety and depression into account within persons with spinal cord injury (SCI). SETTING Persons with SCI, who visited a Dutch rehabilitation centre between 2005 and 2010, were invited to complete a survey. METHODS PTSD symptoms were measured with the Trauma Screening Questionnaire (TSQ), pain intensity with an 11-point Numerical Rating Scale (NRS), and symptoms of anxiety and depression with the Hospital Anxiety and Depression Scale (HADS). To determine associations between PTSD symptoms and pain intensity, linear regression analyses were performed. Confounding variables representing anxiety and depression were added to the final model. RESULTS In total, 175 participants (55.8% traumatic, 29.1% complete) were included (response rate of 31.7%). Of them, 11.4% had clinically relevant symptoms of probable PTSD (TSQ score ≥ 6) 69.8% experienced moderate to severe pain levels (NRS ≥ 4), 14.9% had symptoms of anxiety and 20.8% symptoms of depression (HADS scores ≥ 11). Levels of PTSD symptoms were strongly associated with symptoms of anxiety (0.54) and depression (0.49). Bivariate analyses showed a moderate significant association (0.30) between PTSD symptoms and pain intensity. This association became small (0.10) when anxiety and depression comorbidity were factored into the final regression model. CONCLUSIONS No independent association between PTSD symptoms and pain intensity was shown when adjusted for anxiety and depression. Results of this study suggest the usefulness of screening for PTSD in persons with SCI (regardless of injury cause or type/level) who score high on symptoms of anxiety/depression.

Reg Anesth Pain Med 2021; 46:328-336. [PMID: 33408161 DOI: 10.1136/rapm-2020-101960] [Citation(s) in RCA: 47] [Impact Index Per Article: 15.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 12/04/2020] [Accepted: 12/07/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND The reported prevalence of chronic pain after spinal cord injury (SCI) varies widely due, in part, to differences in the taxonomy of chronic pain. A widely used classification system is available to describe subcategories of chronic pain in SCI, but the prevalence of chronic pain in SCI based on this system is unknown. OBJECTIVE The primary objective of this systematic review and meta-analysis is to determine the prevalence of chronic pain after SCI based on the International Spinal Cord Injury Pain (ISCIP) classification system. EVIDENCE REVIEW A comprehensive search of databases from January 1980 to August 2019 was conducted. The risk of bias was assessed using a modified tool developed for uncontrolled studies. The Grading of Recommendations, Assessment, Development and Evaluation approach was used to assess certainty in prevalence estimates. FINDINGS A total of 1305 records were screened, and 37 studies met inclusion criteria. The pooled prevalence of overall chronic pain was 68% (95% CI 63% to 73%). The pooled prevalence of neuropathic pain in 13 studies was 58% (95% CI 49% to 68%); the pooled prevalence of musculoskeletal pain in 11 studies was 56% (95% CI 41% to 70%); the pooled prevalence of visceral pain in 8 studies was 20% (95% CI 11% to 29%) and the pooled prevalence of nociceptive pain in 2 studies was 45% (95% CI 13% to 78%). Meta-regression of risk of bias (p=0.20), traumatic versus non-traumatic etiology of injury (p=0.59), and studies where pain was a primary outcome (p=0.32) demonstrated that these factors were not significant moderators of heterogeneity. Certainty in prevalence estimates was judged to be low due to unexplained heterogeneity. CONCLUSION This systematic review and meta-analysis extends the findings of previous studies by reporting the prevalence of chronic pain after SCI based on the ISCIP classification system, thereby reducing clinical heterogeneity in the reporting of pain prevalence related to SCI.

Abstract
The prevalence of obesity and of neuropathic pain are both estimated at above 50% in the population of people with chronic spinal cord injury (SCI). These secondary consequences of SCI have significant negative impact on physical functioning, activities of daily living, and quality of life. Investigations of relationships between weight or body composition and chronic neuropathic pain in people with SCI are lacking, but investigations in non-SCI cohorts suggest an association between obesity and the presence and severity of neuropathic pain conditions. In the present article, we present a review of the literature linking obesity and neuropathic pain and summarize findings suggesting that metabolic syndrome and chronic, systemic inflammation due to excess adiposity increase the risk for neuropathic pain after an SCI.

Abstract
After spinal cord injury (SCI), intestinal dysfunction has a serious impact on physical and mental health, quality of life, and social participation. Recent data from rodent and human studies indicated that SCI causes gut dysbiosis. Remodeling gut microbiota could be beneficial for the recovery of intestinal function and motor function after SCI. However, few studies have explored SCI with focus on the gut microbiota and "microbiota-gut-brain" axis. In this review, the complications following SCI, including intestinal dysfunction, anxiety and depression, metabolic disorders, and neuropathic pain, are directly or indirectly related to gut dysbiosis, which may be mediated by "gut-brain" interactions. Furthermore, we discuss the research strategies that can be beneficial in this regard, including germ-free animals, fecal microbiota transplantation, probiotics, phages, and brain imaging techniques. The current microbial research has shifted from descriptive to mechanismal perspective, and future research using new technologies may further demonstrate the pathophysiological mechanism of association of SCI with gut microbiota, elucidate the mode of interaction of gut microbiota and hosts, and help develop personalized microbiota-targeted therapies and drugs based on microbiota or corresponding metabolites.

Abstract
PURPOSE Positive emotions have been found to be analgesic and can be induced by positive psychology exercises. This study tested if positive psychology exercises provide beneficial effects on pain, responses to pain, physical (pain interference), and emotional function. METHODS Randomized parallel-group controlled single-blinded superiority-trial including community-dwelling individuals with chronic pain secondary to spinal cord injury. Participants in the intervention group were instructed to practice 4 personalized positive psychology exercises for 8 weeks. Participants in the control group were asked to be mindful and write about current life events. RESULTS 108 (64%) completed the study. At post-treatment, the intervention participants reported significant reductions in pain intensity and improvements in pain catastrophizing and pain control, relative to baseline. Both groups reported significant decreases in pain interference and negative emotions. Significant between-group differences emerged for pain intensity at post-treatment. At 3-months follow-up, improvements maintained for the intervention group and improvements in positive emotions reached statistical significance. Between-group differences were identified for pain intensity at post-treatment. CONCLUSION Positive psychology exercises represent a potential effective complementary treatment that result in benefits on pain which can be readily implemented into daily living. Trials designed with an inactive control condition should be conducted to further address efficacy. TRIAL REGISTRATION Swiss ethics committee (EKNZ 2014-317)/clinicaltrials.gov (NCT02459028) Registration date: Ethics approval 25.10.2014/Study start date: May 2015 URL of the record: https://clinicaltrials.gov/ct2/show/NCT02459028?term=NCT02459028&cntry=CH&draw=2&rank=1IMPLICATIONS FOR REHABILITATIONPain engenders negative emotions (e.g., fear, anger, sadness) which can negatively affect psychological, social, and physical function.Positive emotions have been found to be analgesic and can be induced by practicing positive psychology exercises.The findings of the current randomized controlled trial provide support for practicing positive psychology exercises (beyond the effects of pain medication intake), in particular on the reduction of pain intensity, but also in improving pain catastrophizing and pain control.The majority of the positive psychology exercises are brief and self-administered positive activities that have no known negative side effects nor financial cost, can be tailored to a person's preferences in activities and can be readily implemented into daily living with chronic pain, complementing standard treatment of pain.

Abstract
INTRODUCTION Increased excitability of the motor cortex through transcranial direct current stimulation (tDCS) has been described as a non-pharmacological strategy for the treatment of Spinal Cord Injury neuropathic pain (SCINP). It is also believed that the ability to enhance motor cortex excitability (MCE) could be impaired within chronic SCINP individuals. The following case reports describe the MCE behavior in individuals with chronic SCINP submitted to electrical non-invasive neuromodulation. CASE PRESENTATIONS This article reports 11 cases with chronic SCINP in which each individual was submitted to a 5-day pre-post MCE analysis in order to evaluate its behavior after the anodal tDCS sessions. All cases maintained ongoing pharmacological treatment. Four individuals have shown negative variation of the MCE, two of which reported pain intensity reduction. Three other individuals had MCE-positive variation along 5 days, from which only one reported a VAS 0.5 pain reduction after the 5th day of observation. The other four individuals did not present significant variation of the MCE. DISCUSSION The positive variation of MCE was significantly altered by adjunctive tDCS only in three individuals, though no clinically relevant reduction in pain intensity was reported among these participants. Key factors such as pain and injury duration, age, chronic medication use and underlying maladaptive neuroplasticity may influence responsiveness to brain stimulation within this population. These case reports try to add evidence for cautious recommendation of tDCS in chronic SCINP individuals and to the necessity of identifying groups of individuals that are most susceptible to neuromodulation.

Abstract
Individuals with spinal cord injury (SCI) often develop debilitating neuropathic pain, which may be driven by neuronal damage and neuroinflammation. We have previously demonstrated that treatment using 670 nm (red) light irradiation alters microglia/macrophage responses and alleviates mechanical hypersensitivity at 7 days post-injury (dpi). Here, we investigated the effect of red light on the development of mechanical hypersensitivity, neuronal markers, and glial response in the subacute stage (days 1-7) following SCI. Wistar rats were subjected to a mild hemi-contusion SCI at vertebra T10 or to sham surgery followed by daily red-light treatment (30 min/day; 670 nm LED; 35 mW/cm2) or sham treatment. Mechanical sensitivity of the rat dorsum was assessed from 1 dpi and repeated every second day. Spinal cords were collected at 1, 3, 5, and 7 dpi for analysis of myelination, neurofilament protein NF200 expression, neuronal cell death, reactive astrocytes (glial fibrillary acidic protein [GFAP]+ cells), interleukin 1 β (IL-1β) expression, and inducible nitric oxide synthase (iNOS) production in IBA1+ microglia/macrophages. Red-light treatment significantly reduced the cumulative mechanical sensitivity and the hypersensitivity incidence following SCI. This effect was accompanied by significantly reduced neuronal cell death, reduced astrocyte activation, and reduced iNOS expression in IBA1+ cells at the level of the injury. However, myelin and NF200 immunoreactivity and IL-1β expression in GFAP+ and IBA1+ cells were not altered by red-light treatment. Thus, red-light therapy may represent a useful non-pharmacological approach for treating pain during the subacute period after SCI by decreasing neuronal loss and modulating the inflammatory glial response.

Abstract
STUDY DESIGN A qualitative study with an emergent design using semi-structured interviews in focus groups. OBJECTIVES To explore the expectations, experiences and desires among individuals who are prescribed drugs for spinal cord injury (SCI) neuropathic pain (NP). SETTING SCI rehabilitation centre. METHODS Eighteen informants with SCI and NP were enrolled. The informants originated from large and small cities in southern Sweden. Data were collected in focus groups consisting of 4-5 individuals in four separate sessions. An emergent design was employed using an interview guide containing open questions. The interviews were transcribed verbatim and data were analyzed according to qualitative content analysis. RESULTS A model of three themes emerged: "Balancing between pain and side-effects" described the difficult choices the informants had to make between drugs and their unwanted side-effects and pain, "Desiring competence and structure in pain management" described the informants wishes regarding pain management and "From hope to personal solutions" described the process from hope of total pain relief from drugs to the development of personal strategies. CONCLUSIONS There is a great need for improvement of SCI-related neuropathic pain management since recommended drugs are insufficiently effective and accompanied by severe side-effects that impact quality of life but also due to structural limitations and physicians' lack of competence in pain management.

Abstract
STUDY DESIGN Scoping review of experimental and quasi-experimental studies. OBJECTIVE To systematically synthesize research testing the effects of leisure time physical activity (LTPA) interventions on chronic pain and subjective well-being (SWB) among adults with spinal cord injury (SCI). METHODS Literature searches were conducted using multiple databases (Web of Science, Embase, CINAHL, Medline, PsychINFO and SPORTDiscus) to identify studies involving persons with SCI that measured and reported the effects of LTPA interventions on both chronic pain and at least one measure of SWB (e.g., affect, life satisfaction, satisfaction with various life domains). Relevant data were extracted from the studies and synthesized. RESULTS A total of 3494 articles were screened. Fifteen published articles, consisting of 12 different studies met the review inclusion criteria. Four different patterns of findings were observed regarding the effect of LTPA on chronic pain and SWB outcomes: (1) increased chronic pain, decreased SWB (1 article); (2) decreased chronic pain, improved SWB (12 articles); (3) increased chronic pain, improved SWB (1 article); and (4) unchanged levels of pain, improved SWB (1 article). CONCLUSIONS Results of most articles included in this scoping review suggest that LTPA interventions can reduce chronic pain and improve SWB for persons with SCI. Further research is needed to identify the mechanisms by which LTPA affects pain and SWB, in order to formulate LTPA prescriptions that maximize improvements in these outcomes.

[PMID: 32891422 DOI: 10.1016/j.apmr.2020.06.020] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Revised: 06/22/2020] [Accepted: 06/23/2020] [Indexed: 11/17/2022]
Abstract
OBJECTIVES To examine prescription opioid claims among individuals with traumatic spinal cord injury (SCI) and to identify factors associated with both chronic opioid and chronic high-dose opioid use. DESIGN Retrospective cohort study using population-level administrative data. SETTING Ontario, Canada. PARTICIPANTS Individuals (N=1842) with traumatic SCI between April 1, 2004 and March 31, 2015. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Proportion of cohort with chronic opioid use (≥90d supply) and proportion with chronic high-dose opioid use (≥90d supply exceeding 90 mg morphine equivalent) between April 1, 2016 and March 31, 2017 (observation period). RESULTS A total of 1842 individuals with traumatic SCI were identified (74% men), with a median age of 51 years (interquartile range [IQR], 34-64y) and median duration of injury of 6 years (IQR, 4-9y). During the observation period, 35% were dispensed at least 1 opioid and 19.8% received chronic opioids, 39% of whom received more than 90 mg daily (chronic high dose). The median daily morphine equivalent dose was 212 mg morphine equivalent (IQR, 135.5-345.3 mg) for chronic high-dose users. Significant risk factors for chronic opioid use were male sex; age between 40 and 60 years; lower income; multimorbidity; thoracic, lumbar, or sacral level of injury; and having a previous diagnosis of osteoarthritis. Risk factors for chronic high-dose opioid use were an extended time since injury, age between 40 and 50 years, and increasing comorbidity. CONCLUSIONS A large proportion of individuals with traumatic SCI were dispensed an opioid in a recent 1-year period. A substantial proportion were dispensed more than 90 mg of morphine equivalents, which is the maximum recommended by the Canadian opioid guideline. Further research is needed to understand the risk factors associated with chronic, high-dose opioid use in this population.

Abstract
Opioid use for chronic pain is limited by severe central adverse effects. We examined whether activating mu-opioid receptors (MORs) in the peripheral nervous system attenuates spinal cord injury (SCI) pain-like behavior in mice. We produced a contusive SCI at the T10 vertebral level and examined motor and sensory dysfunction for 6 weeks. At 6 weeks, we tested the effect of subcutaneous (s.c.) injection of dermorphin [D-Arg2, Lys4] (1-4) amide (DALDA), a peripherally acting MOR-preferring agonist, on mechanical and heat hypersensitivity. Basso mouse scale score was significantly decreased after SCI, and mice showed hypersensitivity to mechanical and heat stimulation at the hind paw beginning at 2 weeks, as indicated by increased paw withdrawal frequency to mechanical stimulation and decreased paw withdrawal latency to heat stimulation. In wild-type SCI mice, DALDA (1 mg/kg, s.c.) attenuated heat but not mechanical hypersensitivity. The effect was blocked by pretreatment with an intraperitoneal injection of methylnaltrexone (5 mg/kg), a peripherally restricted opioid receptor antagonist, and was also diminished in Pirt-MOR conditional knockout mice. DALDA did not adversely affect exploratory activity or induced preference to drug treatment in SCI mice. In vivo calcium imaging showed that DALDA (1, 10 mg/kg, s.c.) inhibited responses of small dorsal root ganglion neurons to noxious heat stimulation in Pirt-GCaMP6s mice after SCI. Western blot analysis showed upregulation of MOR in the lumbar spinal cord and sciatic nerves at 6 weeks after SCI. Our findings suggest that peripherally acting MOR agonist may inhibit heat hypersensitivity below the injury level with minimal adverse effects.

Abstract
Spinal cord injury (SCI) causes neurodegeneration, impairs locomotor function, and impacts the quality of life particularly in those individuals in whom neuropathic pain develops. Whether the time course of neurodegeneration, locomotor impairment, or neuropathic pain varies with sex, however, remains understudied. Therefore, the objective of this study in male and female C57BL/6 mice was to evaluate the following outcomes for six weeks after a 75-kdyn thoracic contusion SCI: locomotor function using the Basso Mouse Scale (BMS); spinal cord tissue sparing and rostral-caudal lesion length; and mechanical allodynia and heat hyperalgesia using hindpaw application of Von Frey filaments or radiant heat stimuli, respectively. Although motor function was largely similar between sexes, all of the males, but only half of the females, recovered plantar stepping. Rostral-caudal lesion length was shorter in females than in males. Mechanical allodynia and heat hyperalgesia after SCI developed in all animals, regardless of sex; there were no differences in pain outcomes between sexes. We conclude that contusion SCI yields subtle sex differences in mice depending on the outcome measure but no significant differences in behavioral signs of neuropathic pain.

Abstract
Spinal cord injury (SCI) is a devastating event with a tremendous impact in the life of the affected individual and family. Traumatic injuries related to motor vehicle accidents, falls, sports, and violence are the most common causes. The majority of spinal lesions is incomplete and occurs at cervical levels of the cord, causing a disruption of several ascending and descending neuronal pathways. Additionally, many patients develop chronic pain and describe it as burning, stabbing, shooting, or shocking and often arising with no stimulus. Less frequently, people with SCI also experience pain out of context with the stimulus (e.g., light touch). While abolishment of the endogenous descending inhibitory circuits is a recognized cause for chronic pain, an increasing number of studies suggest that uncontrolled release of pro- and anti-inflammatory mediators by neurons, glial, and immune cells is also important in the emergence and maintenance of SCI-induced chronic pain. This constitutes the topic of the present mini-review, which will focus on the importance of neuro-immune dysregulation for pain after SCI.

Abstract
Chronic pain is prevalent in intensive care survivors and in patients who require acute care treatments. Many adverse consequences have been associated with chronic post-intensive care and acute care-related pain. Hence, interest in interventions to prevent these pain disorders has grown. To improve the understanding of the mechanisms of action of these interventions and their potential impacts, this article outlines the pathophysiology involved in the transition from acute to chronic pain, the epidemiology and consequences of chronic post-intensive care and acute care- related pain, and risk factors for the development of chronic pain. Pharmacological, nonpharmacological, and multimodal preventive interventions specific to the targeted populations and their levels of evidence are presented. Nursing implications for preventing chronic pain in patients receiving critical and acute care are also discussed.

Abstract
BACKGROUND Pain is common and refractory in spinal cord injury (SCI). Currently, most studies evaluated pain in male-predominant traumatic-SCI. Also, concomitant secondary pain syndromes and its temporal evolution were seldom reported. METHODS We aimed to prospectively describe the main and secondary pain and its associated factors in inflammatory-SCI evaluating neuromyelitis optica (NMO) patients. In-remission NMO patients underwent neurological, imaging and autoantibody evaluations. Questionnaires detailing main and secondary pains, functional state, mood, catastrophizing, quality of life (QoL) and "non-motor symptoms" were used at two time points. RESULTS Pain was present in 53 (73.6%) of the 72 patients included. At-level neuropathic pain was the most common main pain syndrome, affecting 32 subjects (60.4% of those with pain). Over 70% (n = 38) of this cohort reported two pain syndromes. Those without pain were significantly younger (26.1 ± 12.7 y.o. in those without pain and 40.1 ± 12.5, 37.2 ± 11.4 y.o. in those whose main pain was neuropathic and non-neuropathic, respectively, p = .001), and no differences in the inflammatory status were observed between groups. On follow-up, one-fifth (n = 11) had a different main pain syndrome from the first visit. Pain impacted QoL as much as disability and motor strength. CONCLUSION Pain is a prevalent and disabling non-motor symptom in NMO-SCI. Most patients experience more than one pain syndrome which can change in time even in the absence of clinical relapse. Age of the inflammatory-SCI was a major determinant of pain. Acknowledging temporal changes and multiplicity of pain syndromes in NMO-SCI may give insights into more precise designs of clinical trials and general management of pain in SCI. SIGNIFICANCE In this longitudinal study with NMO-related SCI, pain affected almost three-quarters of patients with NMO. Over 70% have more than one pain syndrome and at-level neuropathic pain is the most common type of pain syndrome. Patients without pain were significantly younger but had the same burden of inflammatory lesions than those with pain. During follow-up, up to one fifth of patients presented with changes in the main pain syndromes, which can occur even in the absence of clinical activity of the inflammatory disease. In this cohort, Pain affected quality of life as much as disability or motor strength.

Abstract
INTRODUCTION Globally every year, millions of patients sustain traumatic injuries and require acute care surgeries. A high incidence of chronic opioid use (up to 58%) has been documented in these populations with significant negative individual and societal impacts. Despite the importance of this public health issue, optimal strategies to limit the chronic use of opioids after trauma and acute care surgery are not clear. We aim to identify existing strategies to prevent chronic opioid use in these populations. METHODS AND ANALYSIS We will perform a scoping review of peer-reviewed and non-peer-reviewed literature to identify studies, reviews, recommendations and guidelines on strategies aimed at preventing chronic opioid use in patients after trauma and acute care surgery. We will search MEDLINE, EMBASE, PsycINFO, CINHAL, Cochrane Central Register of Controlled Trials, Web of Science, ProQuest and websites of trauma and acute care surgery, pain, government and professional organisations. Databases will be searched for papers published from 1 January 2005 to a maximum of 6 months before submission of the final manuscript. Two reviewers will independently evaluate studies for eligibility and extract data from included studies using a standardised data abstraction form. Preventive strategies will be classified according to their types and targeted trauma populations and acute care surgery procedures. ETHICS AND DISSEMINATION Research ethics approval is not required as this study is based on the secondary use of published data. This work will inform research and clinical stakeholders on the required next steps towards the uptake of effective strategies aimed at preventing chronic opioid use in trauma and acute care surgery patients.

Abstract
Background Chronic pain (CP) is a real public health concern. It is a common cause of poor quality of life and workplace absenteeism. It is well studied in many medical and surgical fields. However, only few data are available as regards to its occurrence in trauma patients. Purpose To assess the prevalence, associated factors, and psychosocial impact of CP following chest trauma. Methods This is an observational, descriptive, and analytic cross-sectional study performed in a Tunisian department of anesthesia and intensive care over a two-month period. Adult patients admitted one year ago for isolated chest trauma were enrolled. Data were collected by a phone interview. Studied variables were sociodemographic characteristics, traumatic injuries and their management, the occurrence of CP, and its psychosocial impact. CP was diagnosed by the Brief Pain Inventory (BPI) considering an evolution period of at least 3 months. Its impact was assessed by the BPI and the Posttraumatic stress disorder Checklist Scale (PCLS). Results Fifty-four patients were included in the study. The prevalence of CP was 79.6%. The average CP intensity was 3.18 ± 1.4. It was neuropathic in 90.7%. Its main associated factors were pleural effusion (p=0.016), time to ICU admission (p=0.016), time to ICU admission (p=0.016), time to ICU admission (p=0.016), time to ICU admission (. Conclusion CP following chest trauma is frequent and severe requiring preventive measures such as high risk patients screening, better management of acute pain, and a multidisciplinary approach for patients with diagnosed CP.

Abstract
The goal of stem cell therapy for spinal cord injury (SCI) is to restore motor function without exacerbating pain. Induced pluripotent stem cells (iPSC) may be administered by autologous transplantation, avoiding immunologic challenges. Identifying strategies to optimize iPSC-derived neural progenitor cells (hiNPC) for cell transplantation is an important objective. Herein, we report a method that takes advantage of the growth factor-like and anti-inflammatory activities of the fibrinolysis protease, tissue plasminogen activator tPA, without effects on hemostasis. We demonstrate that conditioning hiNPC with enzymatically-inactive tissue-type plasminogen activator (EI-tPA), prior to grafting into a T3 lesion site in a clinically relevant severe SCI model, significantly improves motor outcomes. EI-tPA-primed hiNPC grafted into lesion sites survived, differentiated, acquired markers of motor neuron maturation, and extended βIII-tubulin-positive axons several spinal segments below the lesion. Importantly, only SCI rats that received EI-tPA primed hiNPC demonstrated significantly improved motor function, without exacerbating pain. When hiNPC were treated with EI-tPA in culture, NMDA-R-dependent cell signaling was initiated, expression of genes associated with stemness (Nestin, Sox2) was regulated, and thrombin-induced cell death was prevented. EI-tPA emerges as a novel agent capable of improving the efficacy of stem cell therapy in SCI.
