Evaluation of an interdisciplinary program for chronic pain after spinal cord injury

Disparities Based on Demographic Features in the Intensity and Treatment of Chronic Pain in US Patients With Spinal Cord Injury

OBJECTIVE

Informed by Minority Stress Theory, to investigate disparities in pain intensity, interference, and care in patients with spinal cord injuries (SCI) based on demographic features.

DESIGN

Cross-sectional survey.

SETTING

Outpatient SCI clinics in 2 academic medical centers in the northwestern United States.

PARTICIPANTS

Sample of 242 SCI clinic patients who endorsed SCI-related pain, were ≥18-years-of-age, English-fluent, not diagnosed with bipolar or psychotic disorders, and able to make their own medical decisions. Participants were 74.8% men, an average of 48.5 years (range 18.1-89.8 years), 76.2% White, 31.9% privately insured, and 64.7% making <$50,000 per year.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Exploratory analyses of screening data from a randomized controlled trial for pain treatment. Primary outcomes included pain intensity, pain interference, and the patient report of recommended pain treatments by a medical provider, tried by the patient, or that the patient would be willing to try.

RESULTS

More treatments recommended was associated with younger age (ρ=-0.14, 95% confidence interval [CI]: -0.01 to -0.27, P=.03) and private insurance (ρ=-0.15, 95% CI: 0.02-0.27, P=.03), whereas more treatments tried was associated with private insurance alone (ρ=0.20, 95% CI: 0.07-0.32, P=.003). Number of treatments willing to be tried was associated with lower income (ρ=-0.15, 95% CI: -0.02 to -0.28, P=.03). SCI patients of color (PoC) reported higher pain intensity (Cohen's d=0.41, 95% CI: 0.11-0.71) and greater odds of receiving psychotherapy for pain (odds ratio: 7.12, 95% CI: 1.25-40.46) than their White peers.

CONCLUSIONS

These exploratory findings indicate differences in SCI-related pain intensity based on identifying as PoC, and differences in SCI-related pain treatment modalities based on identifying as PoC, age, insurance type, and income. Further work exploring differences in SCI-related pain care based on patient social identities is warranted.

The effect of neuropathic pain treatments on pain interference following spinal cord injury: A systematic review

CONTEXT

Neuropathic pain is a common and debilitating condition following SCI. While treatments for neuropathic pain intensity have been reviewed, the impact on pain interference has not been summarized.

OBJECTIVE

To systematically review the effect of neuropathic pain interventions on pain interference in individuals with spinal cord injury.

METHODS

This systematic review included randomized controlled trials and quasi-experimental (non-randomized) studies which assessed the impact of an intervention on pain interference in individuals with spinal cord injury and neuropathic pain. Articles were identified by searching MEDLINE (1996 to April 11, 2022), EMBASE (1996 to April 11, 2022), PsycInfo (1987 to April, week 2, 2022). Studies were assessed for methodologic quality using a modified GRADE approach and were given quality of evidence (QOE) scores on a 4-point scale ranging from very low to high.

RESULTS

Twenty studies met the inclusion criteria. These studies fell into the following categories: anticonvulsants (n = 2), antidepressants (n = 1), analgesics (n = 1), antispasmodics (n = 1), acupuncture (n = 2), transcranial direct current stimulation (n = 1), active cranial electrotherapy stimulation (n = 2), transcutaneous electrical nerve stimulation (n = 2), repetitive transcranial magnetic stimulation (n = 1), functional electrical stimulation (n = 1), meditation and imagery (n = 1), self-hypnosis and biofeedback (n = 1), and interdisciplinary pain programs (n = 4).

CONCLUSION

When considering studies of moderate to high quality, pregabalin, gabapentin, intrathecal baclofen, transcranial direct current stimulation, and transcutaneous electrical nerve stimulation (in 1 of 2 studies) were shown to have beneficial effects on pain interference. However, due to the low number of high-quality studies further research is required to confirm the efficacy of these interventions prior to recommending their use to reduce pain interference.

Perspectives of people with spinal cord injury on a pain education resource

Introduction

Spinal cord injury (SCI) often leads to neuropathic pain that negatively affects quality of life. Several qualitative research studies in individuals with SCI who experience neuropathic pain indicate the lack of adequate information about pain. We previously developed an educational resource, the SeePain, based on scientific literature and a series of qualitative interviews of people with SCI, their significant others/family members, and SCI healthcare providers.

Methods

However, to quantitatively evaluate the utility of this educational resource in a larger sample, we examined the agreement and usefulness ratings of statements regarding clarity/comprehensibility, content, and format of the SeePain, derived from the thematic analysis of our previous qualitative interviews. Participants completed a survey that provided a digital version of the SeePain and then rated their agreement/usefulness with the statements using numerical rating scales.

Results

There were overall high perceived agreement and usefulness ratings regarding the SeePain's clarity, content, and format. A factor analysis reduced the agreement and usefulness ratings into 4 components (content, clarity, format, and delivery medium). Group comparisons showed that individuals with higher education were more likely to endorse electronic and website formats, and the usefulness of a shorter version of the SeePain; females and younger individuals showed greater endorsement for clarity. Finally, higher pain intensity ratings were associated with greater agreement and usefulness of the content of the SeePain.

Discussion

Overall, these results support the utility of the SeePain as a source of information regarding pain that may facilitate communication about pain and its management following SCI.

Psychologically based interventions for adults with chronic neuropathic pain: a scoping review

OBJECTIVE

As psychologically based interventions have been shown to have clinical utility for adults with chronic pain generally, a similar benefit might be expected in the management of chronic neuropathic pain (NeuP). However, to date, this has not been established, with existing systematic reviews on this topic being hampered by the scarcity of randomized controlled trials (RCTs). This review aimed to identify the type of psychologically based interventions studied for adults with chronic NeuP. It also aimed to assess whether there are enough RCTs to justify undertaking an updated systematic review.

METHODS

Seven databases and 2 clinical trial registries were searched for NeuP and psychologically based interventions from database inception to December 2021, and the search was updated in February 2023. The search was broadened by reviewing the reference list of included studies and contacting field experts. Predetermined study characteristics were extracted.

RESULTS

Of 4682 records screened, 33 articles (less than 1%) met the eligibility criteria. Four broad intervention approaches were observed, including cognitive-behavioral approaches (n = 16), mindfulness/meditation (n = 10), trauma-focused therapy (n = 4), and hypnosis (n = 3). Thirteen RCTs were identified, and of these, 9 retained 20 participants in each arm after treatment.

CONCLUSIONS

Cognitive-behavioral therapy was the most common therapeutic approach identified, whereas mindfulness/meditation was the most frequently used technique. Almost half to two-thirds of the studies reported significant improvements in pain, disability, or distress, which suggests that psychologically based interventions are potentially beneficial for adults with chronic NeuP. An updated systematic review seems warranted.

Pain in the Context of Sensory Deafferentation

Pain that accompanies deafferentation is one of the most mysterious and misunderstood medical conditions. Prevalence rates for the assorted conditions vary considerably but the most reliable estimates are greater than 50% for strokes involving the somatosensory system, brachial plexus avulsions, spinal cord injury, and limb amputation, with controversy surrounding the mechanistic contributions of deafferentation to ensuing neuropathic pain syndromes. Deafferentation pain has also been described for loss of other body parts (e.g., eyes and breasts) and may contribute to between 10% and upwards of 30% of neuropathic symptoms in peripheral neuropathies. There is no pathognomonic test or sign to identify deafferentation pain, and part of the controversy surrounding it stems from the prodigious challenges in differentiating cause and effect. For example, it is unknown whether cortical reorganization causes pain or is a byproduct of pathoanatomical changes accompanying injury, including pain. Similarly, ascertaining whether deafferentation contributes to neuropathic pain, or whether concomitant injury to nerve fibers transmitting pain and touch sensation leads to a deafferentation-like phenotype can be clinically difficult, although a detailed neurologic examination, functional imaging, and psychophysical tests may provide clues. Due in part to the concurrent morbidities, the physical, psychologic, and by extension socioeconomic costs of disorders associated with deafferentation are higher than for other chronic pain conditions. Treatment is symptom-based, with evidence supporting first-line antineuropathic medications such as gabapentinoids and antidepressants. Studies examining noninvasive neuromodulation and virtual reality have yielded mixed results.

Pain and quality of life in athletes vs non-athletes with spinal cord injury: Observational study

Spinal Cord Injuries (SCI) may cause non-motor symptoms, such as chronic pain, which impair quality of life (QoL)Objective: To investigate the relationship between adapted competitive sports, pain, and QoL in people with SCI in a limited resources setting population.Methods: This prospective cross-sectional observational study involved 16 athletes and 24 non-athletes with SCI and collected data on demographic and clinical variables including scores for pain and pain interference in daily life (Brief Pain Inventory, BPI), neuropathic pain severity (Neuropathic Pain Symptoms Inventory, NPSI) and Quality of life (Word Health Organization Quality of Life Assessment, WHOQOL-BREF). Non-parametric testing was used to compare the groups, and due to athletes being younger, multiple linear regression analyses were used to adjust for the effect of sports practice on the outcome variables when adjusting for age.Results: Athletes were younger (median age 36y) than non-athletes (median age 41.5y; Mann-Whitney U test P = 0.011), and QoL was superior in athletes for the Physical, Psychological, Social Relationships, Self-Evaluation domains, and Total Score when adjusted for age (P < 0.01). Despite having no significant differences in pain intensity scores (NPSI, P = 0.742 and BPI, P = 0.261) athletes had less pain interference on "Relationship with Others", "Enjoyment of Life", and Total score (P < 0.05). Participation in competitive adapted sports (P = 0.004) and Total Pain Interference (P = 0.043) were significantly associated with QoL scores in the multiple linear regression analyses.Conclusion: Athletes with SCI have better QoL and less pain interference in some aspects of life when compared to non-athletes.

Development of a pain self-management intervention framework for people with spinal cord injury

BACKGROUND

 Pain is the most common reason for medical visits to primary health care practitioners. Pain self-management interventions are encouraged and there is no known self-management intervention framework available that clinicians and people with spinal cord injury (PWSCI) can use to guide treatment selection.

AIM

 This study aimed to develop a pain self-management intervention framework for PWSCI.

SETTING

 Online and facilitated in Gauteng, South Africa.

METHODS

 A three-round modified e-Delphi method was used to reach an 80% consensus among a 21-expert panel. Fifty-nine interventions were distributed via REDCap and a final online audio meeting was held to either include or exclude interventions in the final framework. SPSS v27 was used to analyse descriptive data and content analysis was used for qualitative responses.

RESULTS

 The final developed pain self-management framework consists of 56 interventions and includes interventions from multiple health professions to encompass medical, psychological, therapeutic and social interventions. Interventions are also specified for nociceptive and/or neuropathic pain and grouped according to the biopsychosocial model.

CONCLUSION

 The interprofessional framework may be used as a guideline for PWSCI to alleviate pain, as well as assist health professionals in clinical decision-making, by providing them with the freedom to choose acceptable and adequate interventions that may be appropriate to treat the affected individual's pain.Contribution: Pain management is a basic need at the primary healthcare level and PWSCI need access to the broad range of interventions available to manage their pain. The framework highlights the variety of appropriate interventions to guide both health professionals and PWSCI with pain relief options.

A six-participant pilot single-subject study of an individualized pain management program for people with spinal cord injury

STUDY DESIGN

Single-subject repeated measures design.

OBJECTIVES

To explore the impacts of a novel individualized interdisciplinary pain self-management program for persons living with spinal cord injury pain.

SETTING

A large rehabilitation institute for adults with physical disabilities in Quebec city (Quebec, Canada).

METHODS

Six persons having sustained a spinal cord injury and experiencing chronic pain participated. Following a five-week pre-intervention phase (baseline repeated measures) and a clinical evaluation, individualized intervention objectives were developed in collaboration with each participant. Then, participants completed a ten-week intensive intervention and a six-month consolidation phase. The program included cognitive behavioral therapy, and physical and pharmacological interventions, which were group- and individual-based. Outcome measures were the Canadian Occupational Performance Measure (COPM), the French-Canadian Chronic Pain Self-efficacy Scale (FC-CPSES), the Brief Pain Inventory (BPI), and the Hospital Anxiety and Depression Scale (HADS).

RESULTS

For five out of the six participants, a majority of outcomes improved during either of the intervention phases or both. Improvements in occupational performance were clinically significant for three participants. Pain interference and anxiety improved significantly in five participants, while pain self-efficacy and depressive symptoms improved in four participants.

CONCLUSIONS

The results suggest that the pain self-management program was effective to reduce the impact of spinal cord injury pain. Further research is needed to replicate these results in a larger study and comprehend the factors favoring or undermining improvements with such programs, as well as their persistence over time.

Exploration of the Experiences of Persons in the Traumatic Spinal Cord Injury Population in Relation to Chronic Pain Management

Chronic pain amongst individuals with traumatic and nontraumatic spinal cord injury (SCI) has high prevalence rates, with severe impact on the activities of daily living, mood, sleep and quality of life. This study aimed to explore the experiences and challenges of chronic pain management amongst the traumatic spinal cord injury (TSCI) population in the Western Cape region of South Africa. A qualitative descriptive approach was chosen for the study, in which 13 individuals living with TSCI were purposively recruited and interviewed telephonically. An inductive thematic analytic approach was used. The results indicate ineffectiveness of standard pain management, with a lack of education regarding pain physiology and pain management strategies as well as unbalanced decision-making between clinician and patient. Thus, patients develop coping strategies to survive with pain. Current pain regimes are suboptimal at best, underpinned by the lack of clarity or a mutually agreed plan to mitigate and eradicate pain. There is a need for chronic pain management beyond pharmacological prescription. Future practices should focus on adopting a holistic, biopsychosocial approach, which includes alternative pain therapy management. In addition, advances in pain management cannot be achieved without adopting a therapeutic alliance between the clinician and patient.

Pharmacological and non-pharmacological therapeutic interventions for the treatment of spinal cord injury-induced pain

Spinal cord injury (SCI) is a complex neurophysiological disorder, which can result in many long-term complications including changes in mobility, bowel and bladder function, cardiovascular function, and metabolism. In addition, most individuals with SCI experience some form of chronic pain, with one-third of these individuals rating their pain as severe and unrelenting. SCI-induced chronic pain is considered to be "high impact" and broadly affects a number of outcome measures, including daily activity, physical and cognitive function, mood, sleep, and overall quality of life. The majority of SCI pain patients suffer from pain that emanates from regions located below the level of injury. This pain is often rated as the most severe and the underlying mechanisms involve injury-induced plasticity along the entire neuraxis and within the peripheral nervous system. Unfortunately, current therapies for SCI-induced chronic pain lack universal efficacy. Pharmacological treatments, such as opioids, anticonvulsants, and antidepressants, have been shown to have limited success in promoting pain relief. In addition, these treatments are accompanied by many adverse events and safety issues that compound existing functional deficits in the spinally injured, such as gastrointestinal motility and respiration. Non-pharmacological treatments are safer alternatives that can be specifically tailored to the individual and used in tandem with pharmacological therapies if needed. This review describes existing non-pharmacological therapies that have been used to treat SCI-induced pain in both preclinical models and clinical populations. These include physical (i.e., exercise, acupuncture, and hyper- or hypothermia treatments), psychological (i.e., meditation and cognitive behavioral therapy), and dietary interventions (i.e., ketogenic and anti-inflammatory diet). Findings on the effectiveness of these interventions in reducing SCI-induced pain and improving quality of life are discussed. Overall, although studies suggest non-pharmacological treatments could be beneficial in reducing SCI-induced chronic pain, further research is needed. Additionally, because chronic pain, including SCI pain, is complex and has both emotional and physiological components, treatment should be multidisciplinary in nature and ideally tailored specifically to the patient.

The descending pain modulation system predicts short term efficacy of multimodal pain therapy - an observational prospective cohort study

OBJECTIVES

Treating chronic pain patients with multimodal pain therapy (MMPT) alters perception, awareness, and processing of pain at multiple therapeutic levels. Several clinical observations suggest that the effects of therapy may go beyond the possible sum of each level of therapy and may be due to a central descending inhibitory effect measurable by conditioned pain modulation (CPM). Thus, we investigated whether CPM is able to identify a group of patients that benefit particularly from MMPT.

METHODS

This was an observational prospective cohort study. Patients were hospitalized on a special pain medicine ward with specially trained staff for 10 days. The patients were questioned and had investigations before and shortly after MMPT and were followed-up on 3 months post discharge. Before and after treatment, subjects were investigated via CPM and quantitative sensory testing (QST) as well as completing questionnaires. The study was registered in the German Clinical Trials Register (DRKS00006850).

RESULTS

During the study period of 24 months, 224 chronic pain patients were recruited. 51 percent of patients completed the study period. There was an improvement in overall groups regarding all domains assessed, lasting beyond the end of the intervention. Patients with a sufficient CPM effect, defined as a reduction in pain during the conditioning stimulus, at baseline did show a more pronounced reduction in mean pain ratings than those without. This was not the case 3 months after therapy. Furthermore, sufficient CPM was identified as a predictor for pain reduction using a linear regression model.

CONCLUSION

In conclusion, this study shows that while a heterogeneous group of patients with chronic pain disorders does sustainably benefit from MMPT in general, patients with a sufficient CPM effect do show a more pronounced decrease in pain ratings directly after therapy in comparison to those without.

The CanPain SCI clinical practice guidelines for rehabilitation management of neuropathic pain after spinal cord injury: 2021 update

STUDY DESIGN

Clinical practice guidelines.

OBJECTIVES

The objective was to update the 2016 version of the Canadian clinical practice guidelines for the management of neuropathic pain in people with spinal cord injury (SCI).

SETTING

The guidelines are relevant for inpatient, outpatient and community SCI rehabilitation settings in Canada.

METHODS

The guidelines were updated in accordance with the Appraisal of Guidelines for Research and Evaluation II tool. A Steering Committee and Working Group reviewed the relevant evidence on neuropathic pain management (encompassing screening and diagnosis, treatment and models of care) after SCI. The quality of evidence was scored using Grading of Recommendations Assessment, Development and Evaluation (GRADE). A consensus process was followed to achieve agreement on recommendations and clinical considerations.

RESULTS

The working group identified and reviewed 46 additional relevant articles published since the last version of the guidelines. The panel agreed on 3 new screening and diagnosis recommendations and 8 new treatment recommendations. Two key changes to these treatment recommendations included the introduction of general treatment principles and a new treatment recommendation classification system. No new recommendations to model of care were made.

CONCLUSIONS

The CanPainSCI recommendations for the management of neuropathic pain after SCI should be used to inform practice.

An interdisciplinary chronic pain rehabilitation program effectively treats impairment in sexual function, depression, alexithymia, and pain in women with chronic pelvic pain

PURPOSE

Chronic pelvic pain (CPP) in women is often associated with marked emotional distress and disability, with particular impairments in sexual functioning. Research supports the efficacy of interdisciplinary chronic pain rehabilitation programs (ICPRPs) in treating chronic pain, however less is known about their utility in CPP.

METHODS

This retrospective study examined pain-related sexual impairment, emotional symptoms, and pain severity in CPP patients before and after completing a 3-4 week ICPRP. Predictors of post-treatment sexual impairment were also investigated. Participants included 58 female CPP patients and 58 age-matched females with non-pelvic chronic pain (NPCP).

RESULTS

All participants reported robust improvements across outcome measures. Women with CPP reported greater pre- and post-treatment impairment in sexual function than NPCP patients, despite significant treatment-related improvements. In contrast, CPP patients also reported higher levels of depression at baseline but showed greater treatment related-improvements. In participants with CPP, treatment-related improvements in depression, alexithymia, and pain severity significantly explained decreases in pain-related sexual impairment following treatment, whereas none of these variables explained sexual impairment outcomes in women with NPCP.

CONCLUSION

Results demonstrate that ICPRPs can effectively treat CPP, particularly through changes in depression and alexithymia. Future research should examine whether specific interventions can be added in ICPRPS to address CPP-related sexual impairment.

Motor cortical excitability behavior in chronic spinal cord injury neuropathic pain individuals submitted to transcranial direct current stimulation-case reports

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.

Guideline "diagnosis and non interventional therapy of neuropathic pain" of the German Society of Neurology (deutsche Gesellschaft für Neurologie)

2019 the DGN (Deutsche Gesellschaft für Neurology) published a new guideline on the diagnosis and non-interventional therapy of neuropathic pain of any etiology excluding trigeminal neuralgia and CRPS (complex regional pain syndrome). Neuropathic pain occurs after lesion or damage of the somatosensory system. Besides clinical examination several diagnostic procedures are recommended to assess the function of nociceptive A-delta and C-Fibers (skin biopsy, quantitative sensory testing, Laser-evoked potentials, Pain-evoked potentials, corneal confocal microscopy, axon reflex testing). First line treatment in neuropathic pain is pregabalin, gabapentin, duloxetine and amitriptyline. Second choice drugs are topical capsaicin and lidocaine, which can also be considered as primary treatment in focal neuropathic pain. Opioids are considered as third choice treatment. Botulinum toxin can be considered as a third choice drug for focal limited pain in specialized centers only. Carbamazepine and oxcarbazepine cannot be generally  recommended, but might be helpful in single cases. In Germany, cannabinoids can be prescribed, but only after approval of reimbursement. However, the use is not recommended, and can only be considered as off-label therapy within a multimodal therapy concept.

A Scoping Review of Self-Management Interventions Following Spinal Cord Injury

Objective: To conduct a scoping review to identify what components of self-management are embedded in self-management interventions for spinal cord injury (SCI). Methods: In accordance with the approach and stages outlined by Arksey and O'Malley (2005), a comprehensive literature search was conducted using five databases. Study characteristics were extracted from included articles, and intervention descriptions were coded using Practical Reviews in Self-Management Support (PRISMS) (Pearce et al, 2016), Barlow et al (2002), and Lorig and Holman's (2003) taxonomy. Results: A total of 112 studies were included representing 102 unique self-management programs. The majority of the programs took an individual approach (52.0%) as opposed to a group (27.4%) or mixed approach (17.6%). While most of the programs covered general information, some provided specific symptom management. Peers were the most common tutor delivering the program material. The most common Barlow components included symptom management (n = 44; 43.1%), information about condition/treatment (n = 34; 33.3%), and coping (n = 33; 32.4%). The most common PRISMS components were information about condition and management (n = 85; 83.3%), training/rehearsal for psychological strategies (n = 52; 51.0%), and lifestyle advice and support (n = 52; 51.0%). The most common Lorig components were taking action (n = 62; 60.8%), resource utilization (n = 57; 55.9%), and self-tailoring (n = 55; 53.9%). Conclusion: Applying self-management concepts to complex conditions such as SCI is only in the earliest stages of development. Despite having studied the topic from a broad perspective, this review reflects an ongoing program of research that links to an initiative to continue refining and testing self-management interventions in SCI.

An internet-delivered cognitive behavioural therapy pain management programme for spinal cord injury pain: A randomized controlled trial

BACKGROUND

Chronic pain is common after spinal cord injury (SCI) and dedicated SCI cognitive behavioural therapy pain management programmes (CBT-PMPs) have a growing evidence base to support their uptake clinically. The development of internet-delivered treatment options may overcome barriers to the access and uptake of centre-based programmes. This study examines such an approach on quality of lie (QoL), pain, mood and sleep.

METHODS

Adults with SCI pain (>3 months) were recruited and randomly assigned to the intervention or control group. The intervention comprised a six module CBT-PMP delivered once weekly. A blinded assessor determined changes in self-reported outcome measures post-intervention and at 3 months. Linear mixed models and effect sizes based on changes between groups were reported. Significance was set p < 0.05.

RESULTS

The recruitment rate was 32% (intervention n = 35, control n = 34), and the drop-out rate at 3 months was 26%. On average, participants accessed three (SD 2.1) of six modules. While no difference in QoL was reported, a significant group*time interaction was found for NRS of current pain (χ²  = 8.22, p = 0.016), worst pain (χ²  = 11.20, p = 0.004), and Brief Pain Inventory (interference) (χ²  = 6.924, p = 0.031). Moderate to large effect sizes favouring the intervention were demonstrated at each time point for the pain metrics (Cohen's d: 0.38-0.84). At 3-month follow-up, 48% of the intervention group rated themselves improved or very much improved (p < 0.05).

CONCLUSIONS

This study demonstrates the potential of an internet-delivered SCI specific CBT-PMP in reporting significant statistical and clinical benefit in pain intensity and interference. Strategies to improve engagement are needed.

Medicate or Meditate? Greater Pain Acceptance is Related to Lower Pain Medication Use in Persons With Chronic Pain and Spinal Cord Injury

OBJECTIVES

There is little information about whether use of pain self-management skills that are common targets of psychosocial interventions for pain are associated with reduced reliance on pain medications. The aim of this study was to test whether higher chronic pain acceptance, which is a readily modified pain self-management approach, is related to lower use of pain medications (eg, opioid medications, and gabapentinoids) in a sample with chronic pain and spinal cord injury (SCI).

MATERIALS AND METHODS

This is a cross-sectional survey study of pain medication use, pain severity and distribution (Brief Pain Inventory [BPI]), depressive symptoms (Patient Health Questionnaire-9 [PHQ-9]), and chronic pain acceptance (Chronic Pain Acceptance Questionnaire [CPAQ]) administered to a sample of 120 adults with chronic pain and SCI.

RESULTS

Regression results indicated that, above and beyond the effects of pain intensity, pain distribution, and depressive symptoms, higher pain acceptance was related to lower use of all types of pain medications, and lower odds of using opioid medications or gabapentinoids. Pain intensity was not related to pain medication use, but greater pain distribution was related to using more pain medications in general and to greater odds of using gabapentinoids.

DISCUSSION

Findings from this study indicate that those with chronic pain and SCI who have a more accepting orientation to pain are less reliant on pain medications, and thereby experience lower risks associated with medication consumption. Longitudinal, daily process, and clinical trial studies are needed to better understand the association between pain acceptance and pain medication consumption.

What determines low satisfaction with life in individuals with spinal cord injury?

OBJECTIVE

To examine variables associated with satisfaction with life (SWL) in individuals with a spinal cord injury (SCI).

DESIGN

Cross-sectional, national survey to assess SWL, demographic and injury characteristics, health care utilization, chronic conditions (obesity, diabetes, heart problems, lung problems, hypertension, high cholesterol), symptoms (poor sleep, pain, depression), social support, grief/loss, and independence.

SETTING/PARTICIPANTS

Community-dwelling Veterans with SCI. Outcome Measures/Analyses: Bivariate analyses were conducted to assess differences in demographics, injury characteristics, chronic conditions, symptoms, social support, grief/loss, and independence in individuals who reported low SWL (≤20) vs. average/high SWL (21-35). Multivariate logistic regression assessed factors independently associated with low SWL.

RESULTS

896 Veterans with SCI (62%) responded. Average age was 62 years, the majority were male (94%), Caucasian (77%), and had paraplegia (61%). Odds of low SWL were 2.4 times greater for individuals experiencing pain (OR = 2.43, CI95: 1.47-4.02, P = 0.0005). Odds of low SWL were increased for individuals reporting greater grief/loss due to their SCI (OR = 1.14, CI95: 1.10-1.18, P < 0.0001). Lesser odds of low SWL were seen for individuals reporting greater emotional social support (OR = 0.97, CI95: 0.96-0.99, P < 0.0001) and independence (OR = 0.94, CI95: 0.90-0.97, P < 0.0001).

CONCLUSIONS

Pain and feelings of grief/loss due to injury were associated with low SWL. Self-perceived independence and good social support were associated with better SWL. Along with addressing pain and facilitating independence and social support, these findings suggest that interventions to improve SWL should focus on helping individuals deal with grief/loss due to injury.

Pain profiles in a community dwelling population following spinal cord injury: a national survey

CONTEXT

While as many as 60% of patients with spinal cord injury (SCI) develop chronic pain, limited data currently exists on the prevalence and profile of pain post-SCI in community dwelling populations.

STUDY DESIGN

A cross-sectional population survey.

SETTING

Primary care.

PARTICIPANTS

Community dwelling adults with SCI.

METHODS

Following ethical approval members registered to a national SCI database (n=1,574) were surveyed. The survey included demographic and SCI characteristics items, the International Spinal Cord Injury Pain Basic Data Set (version 1) the Douleur Neuropathique 4 questionnaire (interview) and questions relating to health care utilisation. Data were entered into the Statistical Package for the Social Sciences (version 20) Significance was set P < 0.05 for between group comparisons.

RESULTS

In total 643 (41%) surveys were returned with 458 (71%) respondents experiencing pain in the previous week. Neuropathic pain (NP) was indicated in 236 (37%) of responses and nociceptive pain in 206 (32%) Common treatments for pain included medications n=347 (76%) massage n=133 (29%) and heat n=115 (25%). Respondents with NP reported higher pain intensities and increased healthcare service utilisation (P= < 0.001) when compared to those with nociceptive pain presentations. A higher proportion of females than males reported pain (P = 0.003) and NP (P = 0.001) and those unemployed presented with greater NP profiles compared with those in education or employment (P = 0.006).

CONCLUSION

Pain, in particular NP post SCI interferes with daily life, increases health service utilisation and remains refractory to current management strategies. Increased availability of multi-disciplinary pain management and further research into management strategies is warranted.

Self-management of pain and depression in adults with spinal cord injury: A scoping review

Context: Pain and depression are two prevalent secondary complications associated with spinal cord injury (SCI) that negatively impact health and well-being. Self-management strategies are growing in popularity for helping people with SCI to cope with their pain and depression. However, there is still a lack of research on which approaches are best suited for this population.Objective: The aim of this scoping review was to determine what is known about the self-management of pain and depression through the use of pharmacological and non-pharmacological therapies in adults with SCI.Methods: Seven electronic databases were searched for articles published between January 1, 1990 and June 13, 2017. Grey literature was searched and additional articles were identified by manually searching the reference lists of included articles.Results: Overall, forty-two articles met the inclusion criteria; with the majority reporting on the self-management of pain, rather than on depression or on both complications. Non-pharmacological interventions were more likely to include self-management strategies than pharmacological interventions. A limited number of studies included all of the core self-management tasks and skills.Conclusions: There are significant knowledge gaps on effective self-management interventions for pain and depression post-SCI. There is a need to develop interventions that are multi-faceted, which include both pharmacological and non-pharmacological therapies to address multimorbidity.

Quality of life after spinal cord injury: The impact of pain

BACKGROUND

Pain is a common complication after spinal cord injury (SCI). A mixture of nociceptive and neuropathic pain (NP) can present. Limited studies have investigated the impact of different pain phenotypes on quality of life (QoL) post-SCI.

METHODS

Members registered to a national support group for those with SCIs were surveyed (n = 1574). The survey comprised questions relating to demographics and SCI characteristics, The Douleur Neuropathique 4 (DN4) (interview), the International SCI Pain Basic Data Set recording the worst pain and the World Health Organisation Quality of Life BREF (WHOQOL-BREF). An ANCOVA model with post hoc analysis explored between group factors of pain type and intensity of pain categories on QoL, controlling for additional confounding variables. Significance was set p < 0.05. A linear regression explored whether pain intensity, type or interference best predicted QoL.

RESULTS

The response rate was 41% (n = 643), 70% (n = 447) were male. The mean age of respondents was 52 years (SD 14.2) and mean time from SCI was 17 years (SD 12.4). In the previous week, 71% (n = 458) experienced pain, 37% (n = 236) of which had NP as defined in the study. Respondents experiencing NP demonstrated significantly poorer QoL than those without pain (p < 0.001) or nociceptive pain (p < 0.05). Those reporting high pain intensity had significantly lower QoL than those with moderate or no pain (p < 0.001). Pain interference consistently and best-predicted domains of QoL (p < 0.001).

CONCLUSION

High-intensity pain and NP negatively impacts QoL post-SCI. However pain interference more than intensity or type best explains the variance in QoL reported.

SIGNIFICANCE

Neuropathic pain type and severe pain intensities negatively impact QoL after SCI. Pain interference items better predict reported QoL than either pain type or intensity, suggesting better pain management strategies are warranted.

Measuring pain phenomena after spinal cord injury: Development and psychometric properties of the SCI-QOL Pain Interference and Pain Behavior assessment tools

OBJECTIVE

To develop modern patient-reported outcome measures that assess pain interference and pain behavior after spinal cord injury (SCI).

DESIGN

Grounded-theory based qualitative item development; large-scale item calibration field-testing; confirmatory factor analyses; graded response model item response theory analyses; statistical linking techniques to transform scores to the Patient Reported Outcome Measurement Information System (PROMIS) metric.

SETTING

Five SCI Model Systems centers and one Department of Veterans Affairs medical center in the United States.

PARTICIPANTS

Adults with traumatic SCI.

INTERVENTIONS

N/A.

OUTCOME MEASURES

Spinal Cord Injury - Quality of Life (SCI-QOL) Pain Interference item bank, SCI-QOL Pain Interference short form, and SCI-QOL Pain Behavior scale.

RESULTS

Seven hundred fifty-seven individuals with traumatic SCI completed 58 items addressing various aspects of pain. Items were then separated by whether they assessed pain interference or pain behavior, and poorly functioning items were removed. Confirmatory factor analyses confirmed that each set of items was unidimensional, and item response theory analyses were used to estimate slopes and thresholds for the items. Ultimately, 7 items (4 from PROMIS) comprised the Pain Behavior scale and 25 items (18 from PROMIS) comprised the Pain Interference item bank. Ten of these 25 items were selected to form the Pain Interference short form.

CONCLUSIONS

The SCI-QOL Pain Interference item bank and the SCI-QOL Pain Behavior scale demonstrated robust psychometric properties. The Pain Interference item bank is available as a computer adaptive test or short form for research and clinical applications, and scores are transformed to the PROMIS metric.

Outcomes and reflections on a consensus-building workshop for developing a spinal cord injury-related chronic pain research agenda

Context/ Objective: Chronic pain following spinal cord injury (SCI) is a prevalent secondary health condition that significantly impacts quality of life (QoL). Although growing, the number of available effective pain management approaches for SCI is limited. Recognizing the need to "kick-start" activity on this topic, a consensus-building workshop on developing a research agenda for SCI-related chronic pain was held in 2006 with an expert panel. The present paper describes the processes of the consensus-workshop and its associated outcomes towards advancing the research agenda for SCI-related pain in Canada. A commentary on the current state of knowledge regarding SCI-related pain is also provided.

METHODS

Thirty-nine stakeholders (researchers, clinicians, policy-makers, SCI advocates, and people with SCI) attended the consensus-workshop. A modified Delphi approach was employed to gain consensus on identifying the top five SCI pain research priorities for improving QoL post-SCI. As well, project planning along with infrastructure support opportunities were discussed.

RESULTS

The top five pain research priorities were: 1) pain management and treatment; 2) measurement tools; 3) health services policy and advocacy; 4) knowledge transfer; and 5) mechanisms of pain. Recommendations related to the priorities and related resources were generated, and pilot work was initiated.

CONCLUSIONS

The consensus workshop provided an initial roadmap for research on SCI-related chronic pain, and supported five pilot projects on the identified priorities. Reflections on the current research landscape in Canada and abroad suggest increased activity towards addressing pain post-SCI but evidence-based approaches are still lacking.

Change Narratives That Elude Quantification: A Mixed-Methods Analysis of How People with Chronic Pain Perceive Pain Rehabilitation

Chronic pain negatively impacts health, well-being, and social participation. Effective rehabilitation often hinges on long-term changes in pain-related perceptions and behaviors. However, there are important gaps in understanding how patients perceive these changes. The present pilot study addresses this gap by using qualitative and quantitative methodologies to explore how patients perceive and experience changes in function, participation, and pain-related factors following a chronic pain rehabilitation program. A mixed-method design was used in which the core method was qualitative. Descriptive quantitative data was used to further characterize the sample. Semistructured interviews were conducted 1-6 months following treatment completion. Questionnaires were administered before and after treatment and at follow-up. Interview data was analyzed thematically. Participants' individual descriptive data was compared to established cut-scores and criteria for change. A major theme of personal growth emerged in the qualitative analysis. Participants also discussed the factors that facilitated personal growth and the ongoing challenges to this growth. The quantitative data revealed limited improvement on measures of pain, disability, catastrophizing, and depression. These findings suggest that, despite limited improvement on treatment-related questionnaires, patients can experience an important and enduring sense of personal growth. Clinical and theoretical implications are discussed.
