BACKGROUND Patients with chronic pain often have limited access to comprehensive care that includes behavioral pain management strategies. Virtual reality (VR) is an immersive technology and emerging digital behavioral pain therapy with analgesic efficacy for acute pain. We found no scientific literature on skills-based VR behavioral programs for chronic pain populations. OBJECTIVE The primary aim of this study is to evaluate the feasibility of a self-administered VR program that included content and skills informed by evidence-based behavioral treatment for chronic pain. The secondary aim is to determine the preliminary efficacy of the VR program in terms of average pain intensity and pain-related interference with activity, stress, mood, and sleep, and its impact on pain-related cognition and self-efficacy. The tertiary aim was to conduct a randomized controlled trial (RCT) and compare the VR treatment with an audio-only treatment. This comparison isolated the immersive effects of the VR program, thereby informing potential mechanisms of effect. METHODS We conducted an RCT involving a web-based convenience sample of adults (N=97) aged 18-75 years with self-reported chronic nonmalignant low back pain or fibromyalgia, with an average pain intensity &gt;4 over the past month and chronic pain duration &gt;6 months. Enrolled participants were randomly assigned to 1 of 2 unblinded treatments: (1) VR: a 21-day, skills-based VR program for chronic pain; and (2) audio: an audio-only version of the 21-day VR program. The analytic data set included participants who completed at least 1 of 8 surveys administered during the intervention period: VR (n=39) and audio (n=35). RESULTS The VR and audio groups launched a total of 1067 and 1048 sessions, respectively. The majority of VR participants (n=19/25, 76%) reported no nausea or motion sickness. High satisfaction ratings were reported for VR (n=24/29, 83%) and audio (n=26/33, 72%). For VR efficacy, symptom improvement over time was found for each pain variable (all <i>P</i>&lt;.001), with results strengthening after 2 weeks. Importantly, significant time×group effects were found in favor of the VR group for average pain intensity (<i>P</i>=.04), pain-related inference with activity (<i>P</i>=.005), sleep (<i>P</i>&lt;.001), mood (<i>P</i>&lt;.001), and stress (<i>P</i>=.003). For pain catastrophizing and pain self-efficacy, we found a significant declining trend for both treatment groups. CONCLUSIONS High engagement and satisfaction combined with low levels of adverse effects support the feasibility and acceptability of at-home skills-based VR for chronic pain. A significant reduction in pain outcomes over the course of the 21-day treatment both within the VR group and compared with an audio-only version suggests that VR has the potential to provide enhanced treatment and greater improvement across a range of pain outcomes. These findings provide a foundation for future research on VR behavioral interventions for chronic pain.

Abstract Background Chronic pain is one of the most prevalent and disabling symptoms associated with multiple sclerosis (MS). Individuals with MS are interested in nonpharmacologic pain management approaches. Cognitive-behavioral therapy (CBT) is efficacious in improving MS-related pain outcomes. Mindfulness-based cognitive therapy (MBCT) is a promising, alternative approach. Little is known about moderators of these treatments’ outcomes, however. This article describes the study protocol for the first randomized controlled trial comparing MBCT, CBT, and usual care and examining treatment effect moderators in individuals with chronic pain and MS. Methods We will conduct a single-center, randomized, single blind, parallel-group trial comparing MBCT, CBT, and usual care in adults with MS and chronic pain. Both interventions will be delivered via eight group sessions using videoconferencing technology. Primary (average pain intensity) and secondary outcomes (including pain interference, depressive symptoms, fatigue, and sleep) will be assessed pre-treatment, mid-treatment, post-treatment, and at 6-month follow up. Potential treatment moderators will be assessed pre-treatment. We hypothesize that participants randomly assigned to MBCT or CBT will report significantly greater reductions in average pain intensity than participants assigned to usual care at post-treatment (primary study endpoint) and 6-month follow up. We also hypothesize that mindfulness, pain catastrophizing, and behavioral activation pre-treatment will moderate response to both active treatments, but not response to usual care. Discussion Findings will provide important new information about the efficacy and moderators of two nonpharmacologic pain management approaches delivered using technology to overcome common barriers to treatment access. The knowledge gained may lead to better patient-treatment matching and, ultimately, better pain treatment outcomes in MS. Trial registration ClinicalTrials.gov, NCT03782246.

Abstract Background: Pain in sickle cell disease (SCD) has been thought to be episodic, but more recent evidence has shown that individuals in this population also suffer from chronic pain likely resulting from central or peripheral neural damage (neuropathic pain). There is accumulating evidence from human and animal studies indicating potential neuropathic pain in SCD. A number of valid and reliable measures of neuropathic pain have been used to differentiate neuropathic from non-neuropathic types of pain. PAINReportIt, which takes about 10 to 18 minutes to complete, is a computer based self-report pain assessment tool based on the 1970 version of the McGill Pain Questionnaire. From PAINReportIt, a new subscale has been proposed as a measure of neuropathic pain that sums the number of neuropathic pain quality words selected. The PAINReportIt number of neuropathic pain (PR-NNP) scale, however, lacks validation in patients with SCD. Aim: The purpose of this study was to determine the construct validity for the PR-NNP by examining the associations between the PR-NNP and other valid and reliable measures of neuropathic pain (self-administered Leeds Assessment of Neuropathic Symptoms and Signs [S-LANSS] and the Neuropathic Pain Symptom Inventory [NPSI]) among adults with SCD. We hypothesized that the PR-NNP scores would be significantly correlated with S-LANSS and NPSI scores. Methods: This prospective instrument validation study was conducted in an ambulatory research setting with 79 adults diagnosed with SCD who had chronic pain within the prior 12 months (>3 on a 0-10 pain scale). The sample mean age was 36.0 ± 11.5 [ranged from 19-74 years], 63% were female, and 97% reported they were African American. The participants were asked to complete self-reported pain measures (PR-NNP, S-LANSS, NPSI, and PR-NNoc [number of nociceptive pain words]). Descriptive, correlational, and regression analyses were used. Results: Mean scores for average pain intensity, PR-NNP, NSPI, S-LANSS, and PR-NNoc appear in Table 1. Bivariate results indicated moderate correlation between the two validated measures of neuropathic pain (NPSI and S-LANSS; r= .57, p=.000). The NPSI was moderately correlated with PR-NNP (r= .43, p=.000), and weakly correlated with PR-NNoc (r=.35, p=.002). For S-LANSS, there was a moderate correlation with PR-NNP (r=0.41, p=.000) and a weak correlation with PR-NNoc (r=.30, p=.007). There was a weak correlation between average pain intensity and NPSI and S-LANSS, r=.37, p=.001 and r=.36, p=.001, respectively. Regression analysis including average pain intensity, PR-NNP, and PR-NNoc as predictors showed that controlling for PR-NNP and average pain, PR-NNoc was not significantly associated with either NPSI (p=.930) or S-LANSS (p=.731), while each point of increase in PR-NNP was associated with an increase of 1.9 (p=.004) in NPSI and of 0.8 (p=.003) in S-LANSS. The same analysis showed that a one point increase in the average pain intensity was associated with an increase of 2.7 (p=.001) in NPSI and of 1.0 (p=.001) in S-LANSS. Conclusions: Both average pain intensity and PR-NNP but not PR-NNoc have unique explanatory properties of both indicators of neuropathic pain (NPSI and S-LANSS). These findings support the construct validity of the PR-NNP as a potential screening tool for neuropathic pain in patients with SCD. Validation of PR-NNP is important for future neuropathic pain research in the sickle cell population, particularly in cases of multi-site trials, and in cases where the practitioner can detect the potential presence of neuropathic pain without use of expensive equipment. These findings are important because pain management in the sickle cell population often includes opioids, but easy and early detection of neuropathic pain could result in an opioid sparing pain management approach in this population. Disclosures No relevant conflicts of interest to declare.

Introduction: This study examined the prevalence, intensity, interference, and biopsychosocial correlates of pain in a large community-based sample of persons with multiple sclerosis (MS). Methods: Mail surveys were returned by 442 members of the King C ounty (WA) MS Association. Average pain intensity, pain-related activity interference, depressive symptoms and severity of MS were assessed. Results: Forty-four percent reported persistent, bothersome pain in the three months prior to completing the survey. Participants with pain reported an average pain intensity rating of 5.2 (SD =2.3) on the 0 (no pain) to 10 (pain as bad as could be) scale. Twenty-seven percent reported severe pain (score of 7-10), while 51% of those with pain rated the interference of their pain with daily activities as none to minimal. Twenty percent reported severe interference in activities as a result of pain. In multivariate modeling, MS illness severity, marital status, and self-ratings of overall health were significantly associated with pain-related interference with activities. Conclusions: A pproximately a fourth of this sample described having a chronic pain problem characterized by severe pain intensity and significant pain-related interference with activities. Disability due to pain may be more important than previously recognized for the MS population.

Abstract Objectives Sleep disturbances are highly prevalent in patients with chronic pain. However, the majority of studies to date examining sleep disturbances in patients with chronic pain have been population-based cross-sectional studies. The aims of this study were to 1) examine the frequency of sleep disturbances in patients referred to two interdisciplinary chronic pain clinics in Denmark, 2) explore associations between sleep disturbances and pain intensity, disability and quality of life at baseline and follow-up, and 3) explore whether changes in sleep quality mediated the relationships between pain outcomes at baseline and pain outcomes at follow-up. Methods We carried out a longitudinal observational study, examining patients enrolled in two chronic pain clinics assessed at baseline (n=2,531) and post-treatment follow-up (n=657). Patients reported on their sleep disturbances using the sleep quality subscale of the Karolinska Sleep Questionnaire (KSQ), their pain intensity using 0–10 numerical rating scales, their pain-related disability using the Pain Disability Index (PDI), and quality of life using the EuroQol-VAS scale. The average time between baseline and follow-up was 207 days (SD=154). Results At baseline, the majority of patients reported frequent sleep disturbances. We found a significant association at baseline between self-reported sleep disturbances and pain intensity, pain-related disability, and quality of life, where greater sleep disturbance was associated with poorer outcomes. At follow-up, patients reported significant improvements across all pain and sleep outcomes. In two mediation models, we showed that changes in sleep disturbances from baseline to follow-up were significantly associated with (i) pain intensity at follow-up, and (ii) pain disability at follow-up. However, baseline pain intensity and disability scores were not associated with changes in sleep disturbances and, we did not find evidence for significant mediation of either pain outcome by changes in sleep disturbances. Conclusions Self-reported sleep disturbances were associated with pain outcomes at baseline and follow-up, with greater sleep disturbances associated with poorer pain outcomes. Changes in sleep quality did not mediate the relationships between baseline and follow-up scores for pain intensity and disability. These findings contribute to a growing body of evidence confirming an association between sleep and chronic pain experience, particularly suggestive of a sleep to pain link. Our data following patients after interdisciplinary treatment suggests that improved sleep is a marker for a better outcome after treatment.

OBJECTIVE: To evaluate the effects of topical policresulen and cinchocaine in the postoperative pain behavior of open hemorrhoidectomy.METHODS: We conducted a prospective, double-blinded, controlled study. The control group received the usual guidelines with oral medications. The topical treatment group received, in addition, the application of the ointment and was comprised of two subgroups (policresulen + cinchocaine, and placebo). Pain intensity was recorded with the visual analogue scale.RESULTS: 43 patients were operated on: control group - n = 13, one excluded; placebo - n = 15; and policresulen + cinchocaine - n = 15. The mean age was 45.98 years and 37.2% were men. The average pain intensity was 4.09 (immediate postoperative), 3.22 (hospital discharge), 5.73 (day 1) , 5.77 (day 2), 5.74 (day 3), 5.65 (day 7), 5.11 (day 10), 2.75 (day 15) and 7.70 (first bowel movement), with no difference between groups in all periods.CONCLUSION: This study showed no reduction in pain after hemorrhoidectomy with the use of topical policresulen and cinchocaine.

The accuracy of retrospective ratings of pain intensity was examined in a sample of 72 men and 36 women undergoing rehabilitation following anterior cruciate ligament (ACL) reconstructive surgery. Participants completed daily ratings of current, worst, and average pain intensity for the first 42 days of rehabilitation. Participants provided retrospective ratings of worst and average pain intensity twice for a 7-day period (on Days 7 and 21) and once for a 30-day period (on Day 30). Correlations between concurrent and retrospective pain ranged from .74 to .88. Retrospective pain ratings consistently overestimated concurrent pain ratings, but were generally not biased by current pain. The results suggest that retrospective pain ratings can substitute for concurrent pain ratings if the tendency toward overestimation is taken into account.

Studies have shown that pain acceptance is associated with a better pain outcome. The current study explored whether changes in pain acceptance in the very early treatment phase of an interdisciplinary cognitive-behavioral therapy (CBT)-based treatment program for chronic pain predict pain outcomes. A total of 69 patients with chronic, non-malignant pain (at least 6 months) were treated in a day-clinic for four-weeks. Pain acceptance was measured with the Chronic Pain Acceptance Questionnaire (CPAQ), pain outcomes included pain intensity (Numeric Rating Scale, NRS) as well as affective and sensory pain perception (Pain Perception Scale, SES-A and SES-S). Regression analyses controlling for the pre-treatment values of the pain outcomes, age, and gender were performed. Early changes in pain acceptance predicted pain intensity at post-treatment measured with the NRS (B = −0.04 (SE = 0.02); T = −2.28; p = 0.026), affective pain perception at post-treatment assessed with the SES-A (B = −0.26 (SE = 0.10); T = −2.79; p = 0.007), and sensory pain perception at post-treatment measured with the SES-S (B = -0.19 (SE = 0.08); T = -2.44; p = 0.017) . Yet, a binary logistic regression analysis revealed that early changes in pain acceptance did not predict clinically relevant pre-post changes in pain intensity (at least 2 points on the NRS). Early changes in pain acceptance were associated with pain outcomes, however, the impact was beneath the threshold defined as clinically relevant.
