Integrative medicine for chronic pain: A cohort study using a process-outcome design in the context of a department for internal and integrative medicine

[Complementary methods in the treatment of complex regional pain syndrome]

BACKGROUND

Complex regional pain syndrome (CRPS) affects 10-15% of patients following injuries (fractures, surgery) to the outer extremities and people after a stroke. The affected area hurts, is inflamed and lacks strength, while mobility and sensitivity are restricted. Complementary medicine as part of integrative medicine offers additional effective treatment options.

RESEARCH QUESTION

Complementary therapies that extend the guideline recommendations, demonstrate clinical evidence and/or are plausible are presented.

RESULTS

Mind-body medicine procedures (mindfulness, relaxation, yoga, Qi Gong, etc.) support the patient's self-efficacy and stimulate the vagus nerve as well as promoting the reduction of pain, depression and anxiety and improving quality of life. Phytotherapeutics such as turmeric or stinging nettle have an anti-inflammatory effect. Water treatments reduce pain, and acupuncture and neural therapy can be tried.

CONCLUSIONS

Integrative, complementary medical therapy options support the CRPS patient in coping with their disease and the related pain. These options can play an important role in the multimodal, interdisciplinary treatment of this disease.

The Scale of Body Connection: A Multisample Study to Examine Sensitivity to Change Among Mind-Body and Bodywork Interventions

Purpose: The purpose of this measurement study was to examine the Scale of Body Connection (SBC) sensitivity to change among mind-body or bodywork interventions and to explore the concurrent validity in relation to emotion dysregulation and mindfulness skills. Methods: This study was based on multiple clinical trials that had used the SBC to evaluate changes in body awareness (BA) and bodily dissociation (BD) in response to a mind-body or bodywork intervention. To test for sensitivity to change, t tests were used to examine change and estimate effect sizes. To explore convergent validity, Pearson's product-moment correlations between the SBC subscales and Five-Facet Mindfulness Questionnaire (FFMQ) and Difficulties in Emotion Regulation Scale (DERS) were calculated among a subset of the studies, which also included these measures. Results: The BA and BD scales consistently detected significant positive responses to a range of intervention types (yoga, mindfulness meditation, BA, multimodal therapy, and bodywork), demonstrating SBC sensitivity to change. With a few exceptions, the effect sizes across studies for BA were above 0.35, indicating near moderate-to-large effect sizes. The effect sizes for BD, as a measure of responsiveness, were much smaller than for BA; however, four of the studies had effect sizes between 0.54 and 0.86. Concurrent validity with the DERS was supported by moderate-to-large correlations, and with the FFMQ, it was significant with the BA scale in one included study. Conclusions: The results of this study further establish SBC validity and sensitivity to change across a range of mind-body therapies and confirm prior findings of moderate-to-strong internal consistency reliability. The findings support the use of this brief scale to assess key dimensions of BA and BD in practice and research.

Trends in complementary and alternative medicine for the treatment of common mental disorders: A bibliometric analysis of two decades

OBJECTIVE

To investigate the trend of scientific production in relation to the modalities of CAM adopted for the treatment of common mental disorders (CMD), and the evolution and distribution of relevant articles.

MATERIAL AND METHODS

A bibliometric analysis of studies published between 2001 and 2020 was performed, extracted from the Scopus database, using the terms: integrative medicine, complementary therapy, common mental disorders, anxiety and depression, and synonyms. The relationship between the number of publications, and the years studied were analyzed using Pearson's correlation, followed by linear regression to estimate the number of articles along with the year. The VOSviewer software was used to analyze scientometric data. The study looked at countries with the highest number of publications and citations, co-authorships, most frequent keywords, and leading research organizations.

RESULTS

In the analysis of the two decades, we identified a high positive correlation between the number of publications and year (r = 0.945). In trend analysis, the linear regression equation predicted the growth of publications along with the year, with R² = 0.8949 explaining most of the data variability. Spirituality was the most frequent term among the modalities. The concentration of publications and the number of citations were significantly higher in developed countries.

CONCLUSION

The rise in the number of publications in the past two decades on the application of CAM among individuals with CMD suggests a growing scientific interest in Integrative practices. These bibliometric indicators suggest that new studies are warranted, as well as improvements in public health policies.

Characteristics of patients who dropped out after multidisciplinary pain management in Japan: A prospective cohort study

BACKGROUND

Because regular visits to distant hospitals may be a burden to patients, both in terms of time and cost, some patients with chronic musculoskeletal pain may discontinue multidisciplinary pain treatment, unable to maintain motivation to attend.

OBJECTIVE

To evaluate and compare the pre-program characteristics of patients who dropped out and patients who continued treatment, thereby clarifying the characteristics of patients at risk of dropping out.

METHODS

A multidisciplinary pain management treatment program was implemented for patients at the Pain Management Center, Hoshi General Hospital. From April 2015 to March 2018, 23 patients participated in the program. Twelve of the 23 patients lived outside the prefecture where the hospital is located. Of these 12 patients, five completed the program, while seven did not. We compared the dropout and continuation groups in terms of patient characteristics, pain severity, pain-related psychosocial factors, and quality of life.

RESULTS

We found significant differences (p< 0.05) in median age, Japanese Orthopaedic Association Back Pain Evaluation Questionnaire walking ability dysfunction score, and Roland-Morris Disability Questionnaire score.

CONCLUSIONS

The characteristics of patients who dropped out were older age, walking ability dysfunction, and low quality of life associated with low back pain.

Health Disparities in Access to Nonpharmacologic Therapies in an Urban Community

OBJECTIVE

The overuse of prescription opioids for chronic pain is recognized as a public health crisis. Yet, poor access to nonpharmacologic treatments is the norm in low-income, racially and ethnically diverse patients with chronic pain. The main objective of this study was to understand how chronic pain impacts low-income individuals with chronic pain and their communities from multiple perspectives.

DESIGN

This was a qualitative study using a Science Café methodology.

SETTING

The Science Café event was held at an urban community center in Boston, MA.

SUBJECTS

Inclusion criteria included the following: having the ability to attend the event, being at least 18 years of age or older, and participating in English.

METHODS

Data were collected through self-reported questionnaires and audio or video recordings of two focus groups. Quantitative and qualitative data were analyzed with SAS 9.3 and NVivo 10.

RESULTS

Thirty participants attended the Science Café event. The average age was 45 years, 77% reported as female, 42% identified as black, and 19% as Hispanic. Participants identified themselves as either patients (46%) or providers (54%) to the chronic pain community. Our forum revealed three major themes: (1) nonpharmacologic options for chronic pain management are warranted, (2) larger sociodemographic and contextual factors influence management of chronic pain, and (3) both patients and providers value the patient-provider relationship and acknowledge the need for better communication for patients with chronic pain.

CONCLUSIONS

Future research should consider identifying and addressing disparities in access to nonpharmacologic treatments for chronic pain in relation to underlying social determinants of health, particularly for racially and ethnically diverse patients.

A Multidisciplinary Integrative Medicine Team in the Treatment of Chronic Low-Back Pain: An Observational Comparative Effectiveness Study

OBJECTIVES

Chronic low-back pain (CLBP) is burdensome and costly, and a common condition for which adults use integrative therapies. The effectiveness of multidisciplinary integrative approaches has not been well studied. The purpose of this observational study was to compare characteristics and outcomes of CLBP patients treated at the Osher Clinical Center (OCC) versus other clinics at Brigham and Women's Hospital.

DESIGN

Observational comparative effectiveness study.

SETTING

Tertiary care hospital.

SUBJECTS

Patients ≥21 years with 3+ months of CLBP or 6+ months of intermittent low-back pain.

INTERVENTION

All patients were observed for 12 months. OCC patients received care at the integrative clinic (7.3 visits on average over 13 weeks); non-OCC patients received usual care at other clinics of the same hospital.

OUTCOME MEASURES

Primary outcomes: change from baseline to 6 months in functional status (Roland Disability Questionnaire [RDQ]) and bothersomeness of pain (BOP).

SECONDARY OUTCOMES

change in RDQ and BOP at 3 and 12 months, percentages of patients with clinically meaningful (≥30%) improvements.

RESULTS

One hundred fifty-six OCC and 153 non-OCC participants were enrolled; follow-up was 90.4 and 98.0%, respectively, at 12 months. There were substantial differences in baseline characteristics between groups. For RDQ, the adjusted mean group difference was nonsignificant at 6 months; for BOP, the differences were significant, but clinically small. At 12 months, the observed benefit on RDQ was significant and clinically meaningful; for BOP, there were significant, but clinically small differences. Percentages of patients with ≥30% improvements in RDQ were significantly greater in the OCC group only at 12 months, and both 6 and 12 months for BOP.

CONCLUSIONS

Baseline characteristics can differ between those who select different sources of healthcare for CLBP. While benefits seen in the OCC versus non-OCC clinics were not large, further evaluation through randomized trials might be warranted to provide a more definitive evaluation.

Postural awareness and its relation to pain: validation of an innovative instrument measuring awareness of body posture in patients with chronic pain

Background

Habitual postural patterns are associated with musculoskeletal pain, and improving a maladaptive posture requires postural awareness in order to lead to clinical improvements. This study aimed to develop and evaluate the psychometric properties of an innovative postural awareness scale.

Methods

A 12-item Postural Awareness Scale (PAS) was developed and administered to 512 chronic pain patients (50.3 ± 11.4 years, 91.6% female, 37.1% spinal/shoulder pain) to assess its factor structure and reliability. To determine convergent validity, measures of body awareness, body responsiveness, body image, and mindfulness were correlated with the PAS, as were clinical measures of pain intensity, disability, and mental health. Sensitivity to change was assessed in 202 outpatients participating in a 10-week multimodal mind-body program.

Results

Factor analysis revealed two factors (Ease/Familiarity with Postural Awareness and Need for Attention Regulation with Postural Awareness) that explained 50.8% of the variance. Cronbach’s alpha for the complete scale was 0.80; Spearman-Brown coefficient of split-half reliability was 0.67; and intra-class correlation was ICC_2,1 = 0.75 (95% confidence interval = 0.71, 0.78). Significant positive correlations were found for body awareness (r = 0.23), body responsiveness (r = 0.41), body image (r = 0.22–0.32), and mindfulness (r = 0.38); negative correlations for pain intensity (r = − 0.14), disability (r = − 0.12), depression (r = − 0.23), and stress (r = − 0.29). Postural awareness scores increased with a mind-body program (p < 0.001); changes in the PAS were negatively correlated with changes in pain intensity (r = − 0.35) in patients with spinal/shoulder pain.

Conclusion

Self-reported postural awareness is associated with clinical symptoms in chronic pain patients; improvements in postural awareness are longitudinally associated with reduced pain in patients with spinal/shoulder pain.

Being aware of the painful body: Validation of the German Body Awareness Questionnaire and Body Responsiveness Questionnaire in patients with chronic pain

Body awareness is an attentional focus on and awareness of internal body sensations. This study aimed to validate German versions of the Body Awareness Questionnaire (BAQ) and the Body Responsiveness Questionnaire (BRQ) in chronic pain patients and to assess their associations with pain-related variables and to assess their responsiveness to intervention. The instruments were translated to German and administered to 512 chronic pain patients (50.3±11.4 years, 91.6% female) to assess their factor structure and reliability. Cronbach’s α for the BAQ total score was 0.86. Factor analysis of the BRQ revealed the two factors Importance of Interoceptive Awareness (Cronbach’s α = 0.75) and Perceived Connection (Cronbach’s α = 0.75) and the single-item Suppression of Bodily Sensations. The BAQ was independently associated with lower mindfulness, self-esteem, stress, and depression; Importance of Interoceptive Awareness with mindfulness, self-acceptance, self-esteem, and physical contact; Perceived Connection with self-acceptance, vitality, and lower sensory pain; Suppression of Bodily Sensations with lower self-esteem, physical contact, and higher depressive symptoms. After a 10-week multimodal mind-body program (n = 202), the BAQ and Importance of Interoceptive Awareness increased and pain intensity and Suppression of Bodily Sensation decreased. In conclusion, body awareness and body responsiveness are associated with pain-related variables in patients with chronic pain. Mind-body interventions may positively influence both pain and body awareness, hinting at a potential mechanism of action of these interventions to be tested in further research.

Development and implementation of an inpatient multidisciplinary pain management program for patients with intractable chronic musculoskeletal pain in Japan: preliminary report

Introduction

Multidisciplinary pain management is a useful method to treat chronic musculoskeletal pain. Few facilities in Japan administer a multidisciplinary pain management program, especially an inpatient program. Therefore, we implemented a multidisciplinary pain management program in our hospital based on biopsychosocial factors guided by the recommendations of the International Association for the Study of Pain. The purpose of this study is to describe our inpatient pain management program for Japanese patients, which uses the biopsychosocial method of pain self-management.

Materials and methods

Fourteen patients with intractable chronic musculoskeletal pain, who were implemented a multidisciplinary pain management program in our hospital, were studied using the evaluation of the pain and associated factors and physical function.

Results

Significant improvement in outcomes were seen in the brief pain inventory, the pain catastrophizing scale (rumination, magnification, and helplessness), the pain disability assessment scale, the hospital anxiety and depression scale (anxiety and depression), the pain self-efficacy questionnaire, the EuroQol five dimensions questionnaire, and muscle endurance and physical fitness. We found no statistically significant differences in static flexibility or walking ability.

Conclusion

We developed an inpatient chronic pain management program for Japanese patients. Our results suggest that our program improves chronic musculoskeletal pain coping mechanisms, and that the program can improve patients' quality of life and some physical function. This inpatient pain management program is being expanded to better help intractable chronic musculoskeletal pain patients.
