Understanding chronic pain and the mind-body connection

Physical healing as a function of perceived time

In this study we wounded study participants following a standardized procedure and manipulated perceived time to test whether perceived time affected the rate of healing. We measured the amount of healing that occurred across three conditions using a within-subjects design: Slow Time (half as fast as clock time), Normal Time (clock time), and Fast Time (twice as fast as clock time). Based on the theory of mind-body unity-which posits simultaneous and bidirectional influences of mind on body and body on mind-we hypothesized that wounds would heal faster or slower when perceived time was manipulated to be experienced as longer or shorter respectively. Although the actual elapsed time was 28 min in all three conditions, significantly more healing was observed in the Normal Time condition compared to the Slow Time condition, in the Fast Time condition compared to the Normal Time condition, and in the Fast Time condition compared to the Slow Time condition. These results support the hypothesis that the effect of time on physical healing is directly affected by one's psychological experience of time, independent of the actual elapsed time.

Effect of effleurage massage therapy on sleep disturbance, fatigue, pain, and anxiety in patients with multiple sclerosis: A quasi-experimental study

BACKGROUND

Fatigue, pain, sleep disturbance, and anxiety are prevalent symptoms of multiple sclerosis (MS) and frequent complaints in MS patients, which reduce their quality of life. Many studies have shown that massage therapy improves MS patients' symptoms. However, the effect of effleurage massage on sleep disturbance, fatigue, pain, and anxiety in patients with MS is not studied in Egypt.

AIM

To examine the effect of Effleurage massage therapy on sleep disturbance, fatigue, pain, and anxiety in patients with multiple sclerosis (MS).

METHODS

This research study has a quasi-experimental design, with control and intervention groups, and pre and post-tests conducted at the multiple sclerosis in-patient clinic at one Egyptian hospital between May 2019 and January 2020. Sixty adult female patients with MS were recruited, with 30 patients in the control group and 30 in the intervention group. The intervention group received Effleurage massage therapy intervention three times a week for two weeks, and each session lasted about 20 min. Patients in the control group received routine hospital care. Data were collected using the patient's demographic and medical data sheet, Insomnia Severity Index, Modified Fatigue Impact Scale, Numeric Pain Rating Scale, and Beck Anxiety Inventory before and after the intervention.

RESULTS

Significant improvement was observed in pain, sleep, fatigue, and anxiety in the massage group (P < 0.001).

CONCLUSION

Based on the current study, Effleurage massage intervention for MS patients could have possible clinical value for improving sleep disturbance, palliating pain, fatigue, and reducing anxiety. Egyptian nurses can integrate massage therapy into the routine nursing care of patients with MS. Effleurage massage could be an adjunct treatment modality for MS patients; however, more significant studies are needed.

Compensatory coping and depression in women with interstitial cystitis/bladder pain syndrome

INTRODUCTION

Women with genitourinary pain, a hallmark symptom of interstitial cystitis/bladder pain syndrome (IC/BPS), are at a two- to four-fold risk for depression as compared to women without genitourinary pain. Despite the pervasive impact of IC/BPS on psychological health, there is a paucity of empirical research on understanding the relation between IC/BPS and psychological distress. It has been previously reported that women with overactive bladder use increased compensatory coping and these behaviors are associated with heightened anxiety and stress. However, it is unknown whether a similar pattern emerges in IC/BPS populations, as ICBPS and OAB share many similar urinary symptoms. The current study examined the relationship between compensatory coping behaviors and symptoms of psychological distress in a sample of women with IC/BPS to inform understanding of risk and potential mechanisms for intervention.

METHOD

This was a secondary analysis of an observational cohort of women with bladder symptoms. Fifty-five adult women with IC/BPS completed validated assessments of genitourinary symptoms, emotional distress, and bladder coping behaviors. Five compensatory coping behaviors were summed to create a total Bladder Coping Score. Linear regression examined associations between individual coping behaviors, total compensatory coping scores, and other risk variables.

RESULTS

Most (93%) participants reported use of at least one compensatory coping behavior. Age, education level, history of vaginal birth, and symptom severity were all associated with greater compensatory coping scores, and anxiety was not. Beyond the influence of symptom severity, higher levels of depression were significantly associated with higher compensatory coping scores.

DISCUSSION

Greater compensatory coping was associated with increased depression but not anxiety, suggesting different profiles of coping and psychological distress may exist among different types of bladder dysfunction.

A qualitative analysis of pain meaning: results from the Oklahoma Study of Native American Pain Risk (OK-SNAP)

The most widely accepted definition of pain considers it a sensory and emotional experience associated with potential or actual physical harm. However, research tends to generalize findings from predominantly European American samples thereby assuming universality across cultures. Because of the high prevalence of pain within the AI group, it is important to consider whether their conceptualization of pain is similar to the universal definition. To accomplish this aim, a semi-structured interview was conducted with 152 AIs (primarily Southern Plains and eastern Oklahoma tribes) and 150 NHWs. Both groups were asked questions including what words describe hurtful experiences, the purpose of painful experiences, individual and culture-specific meanings of pain, and what constituted the opposite of pain. Many similarities were found between groups as well as differences. For example, NHWs used the word pain more often to describe physically hurtful experiences and were more likely to consider pain to be a signal or warning of an abnormality or pathology. By contrast, only AIs reported culture-specific meanings of pain, such as references to AI rituals or ceremonies. These observed differences are attenuated by small effect sizes. These findings are important to consider when hypothesizing the differences in pain among cultural groups.

Interventions with Music in PECTus excavatum treatment (IMPECT trial): a study protocol for a randomised controlled trial investigating the clinical effects of perioperative music interventions

INTRODUCTION

Pectus excavatum repair is associated with substantial postoperative pain, despite the use of epidural analgesia and other analgesic regimens. Perioperative recorded music interventions have been shown to alleviate pain and anxiety in adults, but evidence for children and adolescents is still lacking. This study protocol describes a randomised controlled trial that evaluates the effects of recorded music interventions on postoperative pain relief in children and adolescents after pectus excavatum repair.

METHODS

A multicentre randomised controlled trial was set up comparing the effects of perioperative recorded music interventions in addition to standard care with those of standard care only in patients undergoing a Nuss procedure for pectus excavatum repair. One hundred and seventy subjects (12-18 years of age) will be included in three centres in the Netherlands. Patient inclusion has started in November 2018, and is ongoing. The primary outcome is self-reported perceived pain measured on the visual analogue scale. Secondary outcomes are anxiety level, analgesics consumption, vital parameters such as heart rate, blood pressure and respiratory rate, length of hospital stay, postoperative complications, quality of life and cost-effectiveness.

ETHICS AND DISSEMINATION

This study is being conducted in accordance with the Declaration of Helsinki. The Medical Ethics Review Board of Erasmus University Medical Centre Rotterdam, The Netherlands, has approved this protocol. Results will be disseminated via peer-reviewed scientific journals and conference presentations.

Yoga for People With Chronic Pain in a Community-Based Setting: A Feasibility and Pilot RCT

The purpose of this feasibility pilot study was to assess benefits of 8 weeks of yoga in people with chronic pain. Participants completed baseline assessments and were randomized to yoga or usual care. Yoga was offered twice a week for 8 weeks. We assessed feasibility and the Brief Pain Inventory (BPI) was the primary outcome, assessing pain-severity and pain interference on daily activities. Eighty-three people were recruited; 67 people completed the study and were included in the analyses. Average age of participants was 50.78 ± 10.43 years and most participants had pain >10 years. The intervention appeared feasible and there were significant improvements (P < .05) in multiple measures for the yoga group, including a decrease in BPI interference scores from 7.15 ± 1.70 to 6.14 ± 2.21 (P = .007). There was a significant difference in body responsiveness and pain management scores between groups at 8 weeks. It appears that yoga was feasible and positively influenced multiple outcome measures for people with chronic pain.

Yoga improves occupational performance, depression, and daily activities for people with chronic pain

BACKGROUND

Chronic pain is a complex accumulation of physical, psychological, and social conditions, thus interventions that address pain and promote occupational performance are needed. A holistic intervention, with mind and body components, is likely necessary to best treat the complexities of chronic pain. Thus, we developed and tested a yoga intervention for people with chronic pain.

OBJECTIVES

In a randomized control trial (RCT), participants with chronic pain were randomized to a yoga intervention or usual care group. Between and within group differences for pre-and post-outcome measure scores were assessed for: occupational performance, completion of activities, and depression.

METHODS

Pilot RCT with participant allocation to 8 weeks of yoga or usual care. Both groups received ongoing monthly self-management programming. Data were collected before and after the 8-week intervention. Participants were randomized to yoga or usual care after baseline assessments. Demographics were collected and measures included: Canadian Occupational Performance Measure (COPM) to assess occupational performance; the 15-item Frenchay Activities Index (FAI)(activities); and the 9-item Patient Health Questionnaire (PHQ-9) for depression. Independent t-tests were used to assess differences between groups. Paired t-tests were used to assess differences between pre- and post 8-week intervention for both the yoga and the usual care groups. Percent change scores and effect sizes were calculated.

RESULTS

83 people were recruited for the study and completed baseline assessments; 44 individuals were randomized to yoga and 39 to the control group. The average age of all participants was 51.4±10.5 years, 68% were female; and 60% had at least some college education. There were no significant differences in demographics or outcome measures between groups at baseline or 8 weeks; however, the study was not powered to see such differences. Individuals randomized to the control group did not significantly improve in any outcome measure over the 8 weeks. There were significant improvements in COPM performance and COPM satisfaction scores for individuals randomized to the yoga group; both scores significantly improved. COPM performance improved by 27% with a moderate to large effect size (3.66±1.85 vs 4.66±1.93, p < 0.001, d = 0.76). COPM satisfaction significantly improved by 78% (2.14±2.31 vs. 3.80±2.50, p < 0.001) and had a large effects size (d = 1.02). FAI scores improved, indicating increased activity or engagement in daily occupation during the 8-week intervention. Scores increased by 5% (38.13±8.48 vs. 39.90±8.57, p = 0.024) with a small effect size (d = 0.37). Depression significantly decreased from 13.21±5.60 to 11.41±5.82, p = 0.041, with a small effect size.

CONCLUSION

Data from this pilot RCT indicate yoga may be an effective therapeutic intervention with people in chronic pain to improve occupational performance, increase engagement in activities, and decrease depression. Occupational therapy practitioners may consider adding yoga as a treatment intervention to address the needs of people with pain.

Factor structure of the Arthritis-Related Health Belief instrument in ethnically diverse community-dwelling older adults with chronic pain

Nonpharmacological treatment of chronic pain in older people can be effective but attitudes and adherence to use of this treatment may differ by ethnicity. This study supports that a modified 14-item instrument based on the modified Health Belief Model-the arthritis-related health belief instrument (AHBI)-can be used across ethnically diverse older adults (i.e., European Americans, Hispanics, African Americans, and Afro-Caribbeans). Confirmatory factor analysis tested the factor structure of the AHBI to eliminate items inappropriate for this population. Structural equation modeling tested expected relationships among four latent variables-severity, susceptibility, barriers, and benefits-across the four ethnic groups. Findings suggest that the modified 14-item AHBI (eliminating two items from the original AHBI) adequately described the four latent factors pertaining to use of nonpharmacological pain therapy in this sample. All items registered substantial loadings (.41-.95) on the hypothesized factors, operating similarly across the four ethnic groups. The modified 14-item AHBI may be useful in (a) assessing how individual perceptions influence access to nonpharmacological pain therapy among ethnically diverse community-dwelling older adults, with the goal to develop and implement effective pain treatment for this population; and (b) measuring the likelihood of using nonpharmacological pain therapy by older adults. The modified 14-item AHBI can help health care providers to provide accurate pain assessment and examine domains that could affect use of nonpharmacological pain therapy by ethnically diverse older adults and guide practice with them by identifying barriers to use of such therapies and providing education to encourage their use.

The effects of massage therapy on multiple sclerosis patients' quality of life and leg function

Background. Massage therapy is a noninvasive treatment that many individuals with multiple sclerosis (MS) use to supplement their conventional treatment. Objective. We hypothesize that massage therapy will improve the leg function and overall quality of life (QoL) of MS patients. Design. A two-period (rest, massage) crossover design was used. Twenty-four individuals with MS ranging from 3.0 to 7.0 on the Expanded Disability Status Scale (EDSS) received Swedish massage treatments for four weeks. Exercise capacity and leg function as well as QoL were assessed using the Six-Minute Walk Test (6MWT) and the Hamburg Quality of Life in Multiple Sclerosis (HAQUAMS) instrument, respectively. Assessments were measured before and after a massage period and a rest period where no massages were employed. Results. The results displayed no significant changes in 6MWT distances or HAQUAMS scores. However, the participants perceived improvement in overall health as expressed in written comments. Conclusions. Massage is a safe, noninvasive treatment that may assist MS patients in managing the stress of their symptoms. Future studies with larger sample size and cortisol measures are warranted.

A narrative approach to explore grief experiences and treatment adherence in people with chronic pain after participation in a pain-management program: a 6-year follow-up study

OBJECTIVE

The aim of this study was to explore grief caused by chronic pain and treatment adherence, and how these experiences are integrated into ongoing life stories.

METHODS

A 6-year follow-up using a qualitative mixed-methods design based on written narratives and image narratives was performed. Five women suffering from chronic pain comprised the purposive sample. They had completed an 8-week group pain-management program with two follow-ups, and thereafter continued as a self-help group. A narrative approach was used to analyze the written and image narratives guided by three analytic steps.

RESULTS

Findings showed that experiences of grief over time were commonly associated with chronic pain. The participants' past experiences reflected their grief at having to abandon jobs and social networks, and revealed loneliness and despair. The present life situation seemed to reflect adaptation, and hope for the future had been established. Overall, forward progression means an ongoing struggle towards a reintegrated body and a meaningful life.

CONCLUSION

Through such narratives, health-care workers can identify treatment adherence related to grief and pain, and learn how people might regain their lives beyond using traditional interviews.

Centering as a model for group visits among women with chronic pelvic pain

Providing comprehensive care for chronic pelvic pain is impeded by time and resource constraints of the standard health care visit. To provide patient education, psychosocial support, and health care assessment, we developed group visits for women with chronic pelvic pain using an evidence-based, holistic nursing approach. In this article, we describe the structure of group visits, the process of conducting Centering group visits focused on empowerment, and the content of a holistic curriculum for women with chronic pelvic pain.

Understanding the paradox of patient pain and patient satisfaction

Pain, in all probability, is the most common symptom experienced by individuals who interact with health care providers. It is understood as a complex and highly individual experience. This complexity is reflected in the paradoxical relationship between patient satisfaction and patient reported pain scores. Using a holistic, caring approach, nurses can optimize the effect of analgesia and facilitate comfort for the person living in pain. Caring for the patient in pain begins with heartfelt compassion and intention to help the person who is suffering. The author describes how the complex relationship and interchange between the patient and the holistic nurse explains the paradox.

Evaluating distance education of a mindfulness-based meditation programme for chronic pain management

Summary

Patients with chronic pain were recruited from two large urban hospitals and from rural hospitals in Ontario. Patients on the waiting list served as controls. The intervention was a Mindfulness-Based Chronic Pain Management course, delivered to patients for two hours per week for 10 weeks. Pre- and postcourse measures of quality of life, pain catastrophizing and usual pain ratings were collected over a period of two years. Patients received the course via traditional face-to-face, in-person teaching (Present site group) or via videoconferencing at their local hospital site (Distant site group). In all, there were 99 Present site participants, 57 at Distant sites and 59 waitlist controls. Patients at Present and Distant sites achieved similar gains in mental health ( P < 0.01) and pain catastrophizing levels ( P < 0.01) relative to controls. However, the Present site group obtained significantly higher scores on the physical dimension of quality of life ( P < 0.01) and lower usual-pain ratings ( P < 0.05) than the Distant site group. The results suggest that videoconferencing is an effective mode of delivery for the Mindfulness course and may represent a new way of helping chronic pain patients in rural areas manage their suffering.

Do Bach flower remedies have a role to play in pain control?

This paper explores the potentiality of Bach flower remedies as a means of pain relief through a retrospective case-study analysis to establish how clients suffering with painful conditions responded to the therapy.

RESULTS

Of 384 subjects, 41 suffered pain. Of these, 46% felt treatment had relieved their pain; in 49% the physical outcome was unknown. About 88% of all subjects reported an improvement in their emotional outlook.

DISCUSSION

The role of placebo and its influence on the study's key features: focus shift from physical pain to emotional outlook, and the importance of the client-practitioner relationship and belief in the therapy.

CONCLUSION

The use of Bach flower remedies has brought about positive emotional changes in the majority of clients in this study. Whilst it is difficult to draw a definitive conclusion as to significance of the therapeutic value of these remedies in relation to pain above that of a placebo, the results are encouraging. In particular, relief of negative emotions and promotion of positive thought including how clients opened up about, and dealt with, emotional issues. The indication is that potential for Bach flower remedies as a therapeutic agent in the relief of pain does exist and is worthy of further qualitative and quantitative investigation through robust, purpose-designed studies to replicate and progress the results shown here.

A structured literature review of pain assessment and management of patients with chronic kidney disease

AIMS AND OBJECTIVES

This paper reviews the literature concerning nurses' assessment and management of pain in adult patients with chronic kidney disease, and proposes implications for clinical practice to support the control of pain in these patients.

BACKGROUND

Chronic kidney disease is a worldwide public health concern with increasing incidence and prevalence, poor patient outcomes and high cost. Patients with kidney disease often experience pain. Optimal pain assessment and management are key clinical activities; however, inadequate pain control by health professionals persists. Renal failure compounds this problem because of the small margin between pain relief and toxicity, and the patient's concomitant health problems.

CONCLUSIONS

The literature review uses 93 articles that were published in medical- and other health-related journals, including 12 medical and pharmaceutical studies specifically relating to pain control in adults with kidney disease. Very little research has been conducted on pain in patients with kidney disease prior to requiring dialysis or kidney transplantation for survival. However, past research showed pain is common and analgesics are underprescribed in patients on dialysis in end-stage kidney disease. The review indicates that an interest in nephrotoxicity and analgesic-induced morbidity dominates over an interest in pain relief in patients with kidney disease. Most analgesics are excreted renally or by the liver, and the use of simple analgesics such as paracetamol is cautioned.

RELEVANCE TO CLINICAL PRACTICE

Findings from the literature review highlight specific difficulties relating to effective pain control in patients with chronic kidney disease. Research is required to identify and overcome barriers to effective pain management, including the development of specific tools to facilitate interventions that optimize analgesic outcomes in patients with chronic kidney disease.

Understanding pain, part 1: physiology of pain

This article is the first in a two-part series which explores pain and its management from a physiological perspective. Pain is a common experience which is often inadequately managed in hospital and community settings. While nurses are in a key position to contribute to successful pain management there are frequent accounts in the literature that nurses lack knowledge about pain management. Knowledge of pain physiology is fundamental to its successful management. This article introduces nurses to the components in the pain pathway and describes nociceptors which respond to pain stimuli and identifies pain fibres which carry pain information to the spinal cord. The processing of pain in the spinal cord is explained and the role of the brain in the manifestation of the pain experience is also explored. The gate control theory of pain and the more recent neuromatrix theory are discussed.

Psychometric Evaluation of Selected Pain Intensity Scales for Use with Cognitively Impaired and Cognitively Intact Older Adults

The purpose of this study was to determine the reliability and validity of selected pain intensity scales such as the Faces Pain Scale (FPS), the Verbal Descriptor Scale (VDS), the Numeric Rating Scale (NRS), and the Iowa Pain Thermometer (IPT) to assess pain in cognitively impaired older adults. A descriptive correlational design was used, and a convenience sample of 66 volunteers age 60 and older residing in assisted living facilities in the South was recruited for this study. The sample included 22 (33%) men and 44 (67%) women, with a mean age of 76. Ninety-eight percent (65) of the sample comprised Caucasian participants, with the exception of 1 African-American man. Seventy percent (47) completed high school and/or college. The mean Mini Mental State Exam (MMSE) score was 16, with a range of 1 to 29. Eighty-five percent scored 24 or lower, indicating some degree of cognitive impairment. The remaining 15% were cognitively intact. All but one participant could use each scale to rate their pain. Concurrent validity of the VDS, NRS, and IPT was supported with Spearman rank correlation coefficients ranging from .78 to .86 in the cognitively impaired group. The FPS, however, demonstrated weak correlations with other scales when used with the impaired group, ranging from .48 to .53. In the cognitively intact group, strong correlations ranging from .96 to .97 were found among all of the scales. Test-retest reliability at a 2-week interval was acceptable in the cognitively intact group (Spearman rank correlations ranged from .67 to .85) and unacceptable for most scales in the cognitively impaired group (correlations ranged from .26 to .67). When asked about scale preference, both the cognitively impaired and the intact groups preferred the IPT and the VDS. This study revealed that cognitive impairment did not inhibit participants' ability to use a variety of pain intensity scales, but the stability issue must be considered.
