ABSTRACT

BACKGROUND: Posttraumatic growth refers to positive psychological change following trauma. However, there is a need to better understand the experience of posttraumatic growth in the palliative care setting as well as the availability and efficacy of interventions that target this phenomenon. AIMS: To provide a review of the prevalence, characteristics and interventions involving posttraumatic growth in adults receiving palliative care and to collate recommendations for future development and utilisation of interventions promoting posttraumatic growth. DESIGN: We performed a systematic scoping review of studies investigating posttraumatic growth in palliative care settings using the Arksey and O'Malley six-step scoping review criteria. We used the PRISMA guidelines for scoping reviews. DATA SOURCES: Articles in all languages available on Ovid Medline [1946-2022], Embase [1947-2022], APA PsycINFO [1947-2022] and CINAHL [1981-2022] in November 2022. RESULTS: Of 2167 articles located, 17 were included for review. These reported that most people report low to moderate levels of posttraumatic growth with a decline towards end-of-life as distress and symptom burden increase. Associations include a relationship between posttraumatic growth, acceptance and greater quality-of-life. A limited number of interventions have been evaluated and found to foster posttraumatic growth and promote significant psychological growth. CONCLUSION: Posttraumatic growth is an emerging concept in palliative care where although the number of studies is small, early indications suggest that interventions fostering posttraumatic growth may contribute to improvements in psychological wellbeing in people receiving palliative care.

ABSTRACT

CONTEXT: Pain management in palliative care remains inadequate; the development of innovative therapeutic options is needed. OBJECTIVES: To determine the feasibility and preliminary effectiveness for larger randomised controlled trials of 3D head-mounted (HMD) virtual reality (VR) for managing cancer pain (CP) in adults. METHODS: Thirteen people receiving palliative care participated in a single-session randomised cross-over trial, after which they completed a qualitative semi-structured interview. We also compared the effects of 3D HMD VR and 2D screen applications on CP intensity and levels of perceived presence. Feasibility was assessed with recruitment, completion rates and time required to recruit target sample. RESULTS: Although recruitment was slow, completion rate was high (93%). Participants reported that the intervention was acceptable and caused few side effects. Although participants reported significantly reduced CP intensity after 3D HMD VR (1.9 Ā± 1.8, P = .003) and 2D screen applications (1.5 Ā± 1.6, P = .007), no significant differences were found between interventions (-.38 Ā± 1.2, 95% CI: -1.1-.29, P = .23). Participants reported significantly higher levels of presence with the 3D HMD VR compared to 2D screen (60.7 Ā± SD 12.4 versus 34.3 Ā± SD 17.1, mean 95% CI: 16.4-40.7, P = .001). Increased presence was associated with significantly lower pain intensity (mean 95% CI: -.04--0.01, P = 0.02). CONCLUSIONS: Our preliminary findings support growing evidence that both 3D and 2D virtual applications provide pain relief for people receiving palliative care. Given the relative lack of cybersickness and increasing access to portable VR, we suggest that larger clinical studies are warranted.

ABSTRACT

Neuropathic pain in people with spinal cord injury is thought to be due to altered central neuronal activity. A novel therapeutic intervention using virtual reality (VR) head-mounted devices was investigated in this study for pain relief. Given the potential links to neuronal activity, the aim of the current study was to determine whether use of VR was associated with corresponding changes in electroencephalography (EEG) patterns linked to the presence of neuropathic pain. Using a within-subject, randomised cross-over pilot trial, we compared EEG activity for three conditions: no task eyes open state, 2D screen task and 3D VR task. We found an increase in delta activity in frontal regions for 3D VR with a decrease in theta activity. There was also a consistent decrease in relative alpha band (8-12 Hz) and an increase in low gamma (30-45 Hz) power during 2D screen and 3D VR corresponding, with reduced self-reported pain. Using the nonlinear and non-oscillatory method of extracting fractal dimensions, we found increases in brain complexity during 2D screen and 3D VR. We successfully classified the 3D VR condition from 2D screen and eyes opened no task conditions with an overall accuracy of 80.3%. The findings in this study have implications for using VR applications as a therapeutic intervention for neuropathic pain in people with spinal cord injury.

ABSTRACT

CONTEXT: Existential and spiritual factors are known to play an important role in how people cope with disability and life-threatening illnesses such as cancer. However, comparatively little is known about the impact of pain on factors such as meaning and purpose in one's life and their potential roles in coping with pain. OBJECTIVES: The aim of this study was to determine spiritual well-being scores in people with persistent pain and to compare these with people with cancer and healthy controls. METHODS: We assessed 132 people with chronic pain, 74 people with cancer (49 with pain and 25 without pain) and 68 control participants using standardised measures of pain-related variables including pain intensity, physical function, mood and cognitions. Spiritual well-being was also assessed using a validated and widely used questionnaire, the Functional Assessment of Chronic Illness Therapy - Spirituality Scale (FACIT-Sp). RESULTS: Spiritual well-being scores were significantly lower in people with persistent pain when compared with controls and were no different when compared with people with cancer, including those who had cancer and pain. In addition, low levels of meaning and purpose were significant predictors of depression, anxiety, and stress across all groups. CONCLUSION: The findings demonstrate that persistent pain is associated with spiritual distress that is equal to those observed in people who have cancer. Furthermore, those who have higher levels of meaning and purpose are less likely to develop mood dysfunction when experiencing pain, indicating they may have a protective role.

ABSTRACT

STUDY DESIGN: Within-subject, randomised cross-over trial. OBJECTIVES: To determine whether a commercially available 3D head-mounted (HMD) virtual reality (VR) device results in significant reductions in neuropathic pain compared to using a 2D screen device in people with spinal cord injury (SCI). SETTING: Greenwich Hospital, Sydney, Australia. METHODS: Sixteen men with established SCI and chronic neuropathic pain participated in a single-session randomised cross-over trial. We compared the effects of 3D HMD VR and a 2D screen application on SCI neuropathic pain intensity and levels of perceived presence. RESULTS: Participants reported significantly lower pain intensity after 3D HMD VR compared to 2D screen application (1.9 Ā± SD 1.8 versus 3.4 Ā± SD 1.6, mean 95% CI: 1.5, P < 0.0001). Participants reported significantly higher perceived levels of presence with the 3D HMD VR compared to 2D screen of (49.6 Ā± SD 8.9 versus 32.8 Ā± SD 11.1, mean 95% CI: 16.6, P < 0.0001). Increased perceived presence was associated with significantly lower pain intensity regardless of randomised sequencing of the two conditions (mean 95% CI: 0.06, P = 0.005). Effect size for pain reduction using 3D HMD VR was 0.80. CONCLUSIONS: We suggest that 3D HMD VR may provide neuropathic pain relief for people with SCI. Given the lack of cybersickness and ease of access, we propose that immersive VR could be a helpful adjunct to current pharmacotherapy. Further research is required to show that VR can be effective for more long-term reductions in SCI pain.

ABSTRACT

This systematic review summarises evidence assessing endogenous pain inhibition in people with irritable bowel syndrome (IBS) compared with healthy controls using conditioned pain modulation (CPM) and offset analgesia (OA). Evidence regarding the role of psychological variables is also examined. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Four electronic databases were searched to retrieve studies assessing CPM or OA in adults diagnosed with IBS according to the ROME II/III criteria. Standardized mean differences were calculated for each study and a random effects model was used for meta-analysis. Eleven studies were included, 5 of which reported results on the relationship between CPM and psychological variables. None of the studies assessed OA. The risk of bias assessment found a lack of assessor blinding in all studies. The pooled effect estimate was 0.90 (95% CI, 0.40-1.40) indicating a significantly lower CPM effect in people with IBS compared with controls. This effect was reduced to 0.51 when 1 outlier was excluded from the analysis. In addition, reduced CPM responses were significantly correlated with higher anxiety (r=0.17 to 0.64), stress (r=0.63), and pain catastrophizing (r=0.38) in people with IBS; however, the evidence available was limited and the strength of these associations variable. Depression was not found to be associated with CPM in these IBS cohorts. The results of this review suggest that people with IBS, as a group, demonstrate reduced pain inhibition measured by CPM. The preliminary evidence about the association between psychological factors and CPM warrants further investigations.

ABSTRACT

BACKGROUND: Pain in people with dementia is a common occurrence. Providing evidence-based pain management for people with dementia in residential aged care services is imperative to providing quality care. However, it remains unclear from current research how various aged care staff (Registered Nurses (RNs), Enrolled Nurses (ENs), Personal Care Assistants (PCAs)) engage at specific points of the pain management pathway. With structural changes to the residential aged care workforce over the past two decades, understanding the relative contributions of these aged care staff to pain management practices is crucial for future practice development. AIM: To investigate the quality and completeness of pain documentation for people living with dementia, and assess the extent to aged care staff are engaged in documentation processes. DESIGN: A three-month retrospective documentation audit. SETTING AND PARTICIPANTS: The audit was conducted on the files of 114 residents with moderate to very severe dementia, across four Australian residential aged care facilities. METHODS: Data was collected on each resident's pain profile (n=114). One hundred and sixty-nine (169) pain episodes were audited for quality and completeness of pain documentation and the extent to which aged care staff (RNs/ENs and PCAs) were engaged in the documentation of pain management. RESULTS: Twenty-nine percent of pain episodes had no documentation about how resident pain was identified and only 22% of the episodes contained an evidence-based (E-B) assessment. At least one intervention was documented for 89% of the pain episodes, the majority (68%) being non-pharmacological. Only 8% of pain episodes had an E-B evaluation reported. Thirteen percent (13%) of episodes contained information across all four pain management domains (Identification/ problems, assessment, intervention and evaluation). Documentation by PCAs was evident at all points in the pain management pathway. PCAs were responsible for considerately more episodes of assessment (50% vs 18%) compared to nursing staff. CONCLUSION AND CLINICAL IMPLICATIONS: Despite the high prevalence of pain in people with dementia in aged care settings, current pain management documentation does not reflect best practice standards. Future capacity building initiatives must engage PCAs, as key stakeholders in pain management, with support and clinical leadership of nursing staff.

ABSTRACT

Trauma to the spinal cord rarely results in complete division of the cord with surviving nerves sometimes remaining silent or failing to function normally. The term motor or sensory discomplete has been used to describe this important but unclassified subgroup of complete SCI. Importantly, silent motor or sensory pathways may contribute to aversive symptoms (spasticity, pain) or improved treatment success. To demonstrate more objectively the presence of subclinical preserved somatosensory pathways in clinically complete SCI, a cross-sectional study using functional MRI (fMRI) was undertaken. The presence of brain activation following innocuous brushing of an insensate region below-injury (great toe) was analyzed in 23 people (19 males (83%), mean Ā± SD age 43 Ā± 13 years) with clinically complete (AIS A) SCI with (n = 13) and without (n = 10) below-level neuropathic pain and 21 people without SCI or pain (15 males (71%); mean Ā± SD age 41 Ā± 14 years). Location appropriate, significant fMRI brain activation was detected in 48% (n = 11/23) of subjects with clinically complete SCI from below-injury stimulation. No association was found between the presence of subclinical sensory pathways transmitting innocuous mechanical stimuli (dorsal column medical lemniscal) and below-level neuropathic pain (χ2 Ā =Ā 0.034, P = 0.9). The high prevalence of sensory discomplete injuries (Ć¢ĀˆĀ¼50% complete SCI) strengthens the case to explore inclusion of this category into the international SCI taxonomy (ISNCSCI). This would ensure more widespread inclusion of discomplete SCI in ongoing pain and motor recovery research. Neurophysiological tests such as fMRI may play a role in this process.

ABSTRACT

BACKGROUND: For many years, spirituality has been regarded as an integral aspect of patient care in fields closely allied to pain medicine such as palliative and supportive care. Despite this, it has received relatively little attention within the field of pain medicine itself. Reasons for this may include a lack of understanding of what spirituality means, doubtfulness of its relevance, an uncertainty about how it may be addressed, or a lack of awareness of how addressing spirituality may be of benefit. METHODS: A review of the literature was conducted to determine the changing conceptual frameworks that have been applied to pain medicine, the emergence of the biopsychospiritual approach and what that means as well as evidence for the benefits of incorporation of this approach for the management of pain. RESULTS: Although the concept of spirituality is broad, there is now greater consensus on what is meant by this term. Many authors and consensus panels have explored the concept and formulated a conceptual framework and an approach that is inclusive, accessible, relevant, and applicable to people with a wide range of health conditions. In addition, there is accumulating evidence that interventions that address the issue of spirituality have benefits for physical and emotional health. CONCLUSIONS: Given the firm place that spirituality now holds within other fields and the mounting evidence for its relevance and benefit for people with pain, there is increasing evidence to support the inclusion of spiritual factors as an important component in the assessment and treatment of pain.

ABSTRACT

PURPOSE: Rebuilding a strong sense of meaning and purpose following trauma is a vital contributor to post-traumatic growth and adapting well to a spinal cord injury. This project aimed to develop an intervention that used the concept of post-traumatic growth to foster a stronger sense of meaning and purpose in people with a spinal cord injury. METHODS: Using participatory action research methodology, the intervention was designed in an iterative process with health professionals and people with lived experience of spinal cord injury. We developed a ten-week online group program and delivered two pilot programs to 13 participants. We used their feedback to further refine the program before finalisation. RESULTS: A participatory action research approach resulted in a positive intervention well received by participants and consumer organisations. Feedback suggests the intervention shows promise for improvements in functional and psychosocial outcomes and has long-term viability. CONCLUSIONS: The project successfully developed and delivered a novel program that uses the concept of post-traumatic growth to foster a stronger sense of meaning and purpose. Further implementation of the program with larger numbers will allow for evaluation of the program's effectiveness.


Group-based intervention programs based on principles of post-traumatic growth can help people with spinal cord injury explore meaning and purpose.Co-design, development and implementation of interventions help to ensure such programs appeal to consumers, meet their needs, and are sustainable.Interventions can be delivered effectively online.

ABSTRACT

PURPOSE: To date, no evidence-based, community-based online group intervention has been designed specifically to enhance posttraumatic growth (PTG), quality of life (QoL), sense of meaning and purpose, and satisfaction with life following a spinal cord injury (SCI). This qualitative study aims to describe participants' experiences of participating in such a program. METHODS: Semi-structured interviews were conducted with 17 people with SCI and analysed using a thematic analysis approach. RESULTS: Five major themes were identified: longing for connection; empowerment through education and participation; journeying through common experiences; connecting to the program content; and continuing to contemplate PTG and meaning and purpose. The themes represent how participants were drawn to the program because they longed to connect with others in similar situations. Participants engaged in a shared group process of learning and reflection as well as an individual journey in which they connected with different elements of the program. As a result, PTG was seen as a continuous and individual process that evolved out of shared group processes. CONCLUSIONS: This study highlights the importance of addressing psychological needs alongside physical rehabilitation for individuals with SCI. Shared experiences and strength-based approaches can be valuable tools in promoting positive psychological outcomes.


This article reports on the impact of a novel community-based, online, group intervention, the Engage program, aimed at facilitating the recognition or generation of post-traumatic growth for people with spinal cord injuries.The program offers a safe space where participants can explore the impact that acquiring a spinal cord injury can have on their sense of meaning and purpose and identify where they could build this again in their lives.Breaking down the concepts of posttraumatic growth (PTG) and meaning and purpose into questions like "what gets me out of bed in the morning" and "what fills my cup" helps people with spinal cord injuries understand and relate to these existential topics.Engaging participants in group conversation and reflection on the concepts of PTG and meaning and purpose helps stimulate individual reflection outside the group.Individual coaching sessions are vital to putting the program content into practice for participants individually.

ABSTRACT

Loss of somatosensory drive results in functional reorganization of the primary somatosensory cortex (SI). While the phenomenon of functional cortical reorganization is well established, it remains unknown whether in humans, functional reorganization results from changes in brain anatomy, or simply reflects an unmasking of already existing dormant synapses. In 20 subjects with complete thoracic spinal cord injuries (SCIs) and 23 controls, we used functional and structural magnetic resonance imaging to determine whether SI reorganization was associated with changes in SI anatomy. SCI resulted in a significant SI reorganization, with the little finger representation moving medially toward the lower body representation (i.e., area of sensory loss). Furthermore, although SCI was associated with gray matter volume loss in the lower body representation, this loss was minimized as reorganization increased. That is, the greater the medial shift in little finger representation, the greater the gray matter preservation in the lower body representation. In addition, in the region of greatest SI reorganization (little finger), fractional anisotropy was correlated with SI reorganization. That is, as SI reorganization increased, the extent of aligned structures decreased. Finally, although thalamocortical fibers remained unchanged, the ease and direction of water movement within the little finger representation was altered, being directed more toward the midline in SCI subjects. These data show that SI reorganization following SCI is associated with changes in SI anatomy and provide compelling evidence that SI reorganization in humans results from the growth of new lateral connections, and not simply from the unmasking of already existing lateral connections.

ABSTRACT

The effective management of pain is a complex and costly global issue, requiring a range of innovative educational strategies to enable culturally appropriate and high-quality health care provision. In response to this issue, the Pain Management Research Institute at the University of Sydney (Sydney, Australia) has established several strategic alliances with other overseas universities to deliver online postgraduate education in pain management. The present article discusses the rationale for joining forces, and the approach adopted in creating and maintaining these alliances. It also provides insights into the benefits, challenges and opportunities associated with collaborative educational initiatives of this nature, from institutional, academic and student perspectives.

ABSTRACT

Context: Virtual and augmented imagery are emerging technologies with potential to reduce the severity and impact of neuropathic pain in people with spinal cord injury (SCI).Objective: We aimed to identify and discuss studies using virtual and augmented reality applications for the management of neuropathic pain in people with spinal cord injury.Methods (data sources, data extraction): A systematic literature search was conducted using PRISMA scoping review guidelines. Articles were searched in PubMed, Embase and Web of Science databases using search terms relating to SCI, virtual and augmented reality and neuropathic pain. With no strong evidence for visual imagery in the treatment of pain in SCI patients, we selected exploratory, feasibility and more rigorous methodologies such as randomized controlled trials and case-control studies. We only selected studies evaluating the effects of visual imagery on neuropathic pain at or below the spinal cord injury level.Results: Of 60 articles located, we included nine articles involving 207 participants. All studies were exploratory using head-mounted devices or 3D and 2D screens with virtual walking or limb movement imagery. Outcomes included pain sensitivity, motor function and body ownership. Eight of the nine studies reported significant reductions in neuropathic pain intensity. However, given small sample sizes in all studies, results may be unreliable.Conclusion: Although the number of studies and individual sample sizes are small, these initial findings are promising. Given the limited options available for the effective treatment of neuropathic SCI pain and early evidence of efficacy, they provide valuable incentive for further research.

ABSTRACT

Spinal cord injury (SCI) can be accompanied by chronic pain, the mechanisms for which are poorly understood. Here we report that magnetic resonance spectroscopy measurements from the brain, collected at 3T, and processed using wavelet-based feature extraction and classification algorithms, can identify biochemical changes that distinguish control subjects from subjects with SCI as well as subdividing the SCI group into those with and without chronic pain. The results from control subjects (n=10) were compared to those with SCI (n=10). The SCI cohort was made up of subjects with chronic neuropathic pain (n=5) and those without chronic pain (n=5). The wavelet-based decomposition of frequency domain MRS signals employs statistical significance testing to identify features best suited to discriminate different classes. Moreover, the features benefit from careful attention to the post-processing of the spectroscopy data prior to the comparison of the three cohorts. The spectroscopy data, from the thalamus, best distinguished control subjects without SCI from those with SCI with a sensitivity and specificity of 0.9 (Percentage of Correct Classification). The spectroscopy data obtained from the prefrontal cortex and anterior cingulate cortex both distinguished between SCI subjects with chronic neuropathic pain and those without pain with a sensitivity and specificity of 1.0. In this study, where two underlying mechanisms co-exist (i.e. SCI and pain), the thalamic changes appear to be linked more strongly to SCI, while the anterior cingulate cortex and prefrontal cortex changes appear to be specifically linked to the presence of pain.

ABSTRACT

Background and aims The purpose of this study was to (a) develop and (b) conduct exploratory factor analysis on a novel self-report instrument for symptoms associated with altered central pain processing. Methods We first developed a 25-item questionnaire based on previous literature identifying symptoms and behaviours that may reflect altered spinal and supraspinal pain processing. We then administered this questionnaire to 183 people with chronic pain (n = 99) and healthy individuals (n = 84). Exploratory factor analysis was conducted to identify the factor structure of the questionnaire. Results Our results support a two-factor solution for the 25-item questionnaire that accounted for 57.2% of the total variance of responses in people with and without chronic pain. Factor one (11 items) included items related to alterations in sensation of pain, while factor two (seven items) included items associated with emotional and fatigue symptoms. Seven items showed weak factor loadings and were eliminated. Reliability was excellent, while both factors showed strong correlations with previously-validated self-report Instruments: (pain catastrophising, mood, vigilance, pain self-efficacy) and conditioned pain modulation, providing evidence for their validity. Conclusions We have developed a questionnaire containing two factors that appear to be related to two different symptom clusters, one of which is specifically related to pain and one of which contains other health-related symptoms related to mood and fatigue. These factors show excellent internal consistency and validity. This questionnaire may be a quick, easy and reliable instrument to assess central pain processing in clinical settings.

ABSTRACT

Chronic pain is one of the more disturbing sequelae of spinal cord injury, often interfering with the basic activities, effective rehabilitation, and quality of life of the patient. Pain in the cord-injured patient is often recalcitrant to treatment. This dilemma is amplified by the limited availability of effective pharmacological and nonpharmacological treatment options. We identified relevant articles regarding pain after spinal cord injury from the Medline database from 1975 to 2005 using the search terms "spinal cord injury" or "spinal cord injuries" and "pain" or "spasticity or "muscle spasms." We also searched by hand the review articles in a recently published book from the International Association for the Study of Pain Press on spinal cord injury pain, and identified relevant articles through reference lists. We present a patient with intractable spinal cord injury pain who was successfully treated with a pain management plan that addressed the various aspects of spinal cord injury pain. The evidence for treatment options is reviewed.
