Guided Imagery for Arthritis and Other Rheumatic Diseases: A Systematic Review of Randomized Controlled Trials

The Effectiveness of Psychological Interventions for Rheumatoid Arthritis (RA): A Systematic Review and Meta-Analysis

Rheumatoid arthritis (RA) is a long-term disorder that significantly impairs somatic, emotional, and psychological functioning. The objective of this review is to identify, appraise, and synthesize the effects of psychological interventions (e.g., cognitive behavioral therapy (CBT), emotional disclosure (ED), group therapy (GT), mindfulness (M), patient education (PE), and relaxation (R)) on biopsychosocial outcomes in the treatment of rheumatoid arthritis (RA). A systematic search of all relevant existing randomized clinical trials (RCTs) was conducted using the following online bibliographic databases: JSTOR, PubMed, PsycNET, and The Cochrane Library. Reference lists were searched for additional reports. The Cochrane Risk of Bias tool (RoB 2.0) was used to assess the risk of bias in the included studies. After the selection process, 57 articles were included and 392 were excluded. Three separate meta-analyses were conducted involving psychological interventions as the main variables, showing: (1) significant positive medium effect sizes for average values (Hedges-g = 0.399, Z = 0.399, p = 0.009); (2) significant positive large effect sizes for maximum values (Hedges-g = 0.856, Z = 4.223, p < 0.001); and (3) non-significant results for minimum values (Hedges-g = -0.047, Z = -0.335, p = 0.738). These results demonstrate that, when grouped, psychological interventions are, on average, moderately effective in treating RA. Overall, this review shows consistent, supportive evidence that psychological interventions can significantly contribute to the standard medical care of RA patients. However, more high-quality, large-sample RCTs still need to confirm these findings.

Development and validation of audio-based guided imagery and progressive muscle relaxation tools for functional bloating

Mind-body techniques, including Guided Imagery (GI) or Progressive Muscle Relaxation (PMR), may effectively manage bloating. The current study aimed to develop and validate (psychometric and psychological responses) audio-based GI and PMR techniques for bloating. Audio scripts were first developed from literature reviews and in-depth interviews of participants with bloating diagnosed based on the Rome IV criteria. Scripts were validated using psychometric (content & face validity index) and physiological approaches (brain event-related potentials & heart rate variability). 45/63 participants completed the in-depth interview, and ‘balloon’ emerged as the synonymous imagery description for bloating, of which inflation correlated with a painful sensation. The final tools consisted of narrated audio scripts in the background of a validated choice of music. Overall, the content and face validity index for PMR and GI ranged from 0.92 to 1.00. For ERP and HRV, 17/20 participants were analyzed. For ERP, there was a significant difference between GI and PMR for alpha waves (p = 0.029), delta waves (p = 0.029), and between PMR and control for delta waves (p = 0.014). For HRV, GI and PMR exhibited similar autonomic responses over controls (overall p<0.05). The newly developed GI and PMR audio-based tools have been validated using psychometric and physiological approaches.

Modulatory Effects of Actual and Imagined Acupuncture on the Functional Connectivity of the Periaqueductal Gray and Ventral Tegmental Area

OBJECTIVE

Both acupuncture and guided imagery hold promise for treating pain. The mechanisms underlying these alternative interventions remain unclear. The reported study aimed to comparatively investigate the modulation effect of actual and imagined acupuncture on the functional connectivity of descending pain modulation system and reward network.

METHODS

Twenty-four healthy participants (mean [standard error], 25.21 [0.77] years of age; 66.67% female) completed a crossover study that included five sessions, a training session and four intervention sessions administered in randomized order. We investigated the modulation effect of real acupuncture, sham acupuncture, video-guided acupuncture imagery treatment (VGAIT) and VGAIT control on the resting-state functional connectivity (rsFC) of periaqueductal gray (PAG) and ventral tegmental area (VTA). These are key regions of the descending pain modulatory system and dopaminergic reward system, respectively.

RESULTS

Compared with sham acupuncture, real acupuncture produced decreased PAG-precuneus (Pcu) rsFC and increased VTA-amygdala/hippocampus rsFC. Heat pain threshold changes applied on the contralateral forearm were significantly associated with the decreased PAG-Pcu (r = 0.49, p = .016) and increased VTA-hippocampus rsFC (r = -0.77, p < .001). Compared with VGAIT control, VGAIT produced decreased PAG-paracentral lobule/posterior cingulate cortex/Pcu, middle cingulate cortex (MCC), and medial prefrontal cortex rsFC, and decreased VTA-caudate and MCC rsFC. Direct comparison between real acupuncture and VGAIT showed that VGAIT decreased rsFC in PAG-paracentral lobule/MCC, VTA-caudate/anterior cingulate cortex/nucleus accumbens, and VTA-MCC.

CONCLUSIONS

Results suggest that both actual and imagined acupuncture can modulate key regions in the descending pain modulatory system and reward networks, but through different pathways. Identification of different pain relief mechanisms may facilitate the development of new pain management methods.

The Impact of Guided Imagery on Pain and Anxiety in Hospitalized Adults

BACKGROUND

The use and impact of guided imagery in the acute care setting is limited.

AIMS

The purpose of this quality improvement project was to evaluate the feasibility of a guided imagery intervention to change pain scores, anxiety scores, and opioid analgesia usage among hospitalized adults in an acute care setting.

DESIGN

Quality improvement project using three measurements (baseline, 24 hours, and 48 hours).

SETTINGS

Acute care hospital.

PARTICIPANTS/SUBJECTS

Adult inpatients referred to an APRN-led pain management service.

METHODS

The intervention was the use of a 30-minute guided imagery recording delivered via MP3 player which patients used twice daily.

RESULTS

Limited changes were seen in pain scores, with no statistically significant results (p = .449). Statistically significant reductions were found in both anxiety scores (p < .001) and opioid analgesia usage (p = .043).

CONCLUSIONS

Findings from this quality improvement project support the impact of guided imagery on anxiety and opioid analgesia use. Changes in pain scores were not demonstrated in this project. Additional research with a rigorous design is needed to determine cause and effect conclusions.

CLINICAL IMPLICATIONS

The use of guided imagery as an adjunctive intervention for pain control may engage and empower the patient in self-care activities, which may have an impact on how care is perceived. Guided imagery is a low-cost, easily implemented approach that can be incorporated into patient care to reduce anxiety and, potentially, opioid analgesia use.

Applying the Power of the Mind in Acupuncture Treatment of Pain

Background: Healing is a complicated process that can have several components including the self-healing properties of the body, the nonspecific effects of treatment (e.g., the power of the mind), and the specific effects of an intervention. This article first discusses the brain imaging studies on placebo acupuncture analgesia and the modulation effects of expectancy on real acupuncture in healthy subjects. Then, it introduces some attempts to translate findings from healthy subjects to patient population using power of the mind as a way to enhance acupuncture's treatment effects on chronic pain. After that, a new alternative method which merges acupuncture and imagery, while also drawing on power of the mind, is presented. Finally, the specific effects of acupuncture are discussed. Conclusions: Elucidating the mechanism underlying power of the mind would provide new opportunities for boosting the therapeutic effect of acupuncture treatment and furthering the development of new alternative interventions.

Mind-Body Interventions for Rehabilitation Medicine: Promoting Wellness, Healing, and Coping with Adversity

Physical medicine providers work to cure organic aspects of disease while simultaneously enhancing quality of life and well-being. Mind-body interventions are evidence-based, cost-effective approaches to serve these aims. This article enhances provider knowledge and acceptance of the most effective and prevalent mind-body modalities: meditation, guided imagery, clinical hypnosis, and biofeedback. The scientific evidence is strongest for mind-body applications for chronic pain, primary headache, cardiac rehabilitation, and cancer rehabilitation, with preliminary evidence for traumatic brain injury and cerebrovascular events. Mind-body interventions are well-tolerated by patients and should be considered part of standard care in physical medicine and rehabilitation settings.

Imagined and Actual Acupuncture Effects on Chronic Low Back Pain: A Preliminary Study

Background

Research suggests that imagined experiences can produce brain responses similar to those produced by actual experiences. Shared brain responses that support both imagination and perception may underlie the functional nature of mental imagery. In a previous study, we combined acupuncture and imagery to develop a new treatment method, video-guided acupuncture imagery treatment (VGAIT). We found that VGAIT significantly increased pain thresholds in healthy subjects. The aim of this study is to extend our previous finding by investigating whether VGAIT can relieve symptoms in patients with chronic low back pain.

Methods

We first performed a single-arm study in which we administered video-guided acupuncture imagery treatment (VGAIT) on patients with chronic low back pain (cLBP) (Study 1, n = 18, 12 females). We then compared our findings to those from a recently published study in which real or sham acupuncture treatment was applied on patients with cLBP (Study 2, n = 50, 31 females) using a similar protocol. All patients in Studies 1 and 2 received 6 treatments over 4 weeks.

Results

All three treatments (VGAIT, real, and sham acupuncture) significantly reduced pain severity as measured by a low back pain bothersomeness score. VGAIT produced similar effects to real acupuncture (p = 0.97) and nonsignificantly greater pain bothersomeness relief compared to sham acupuncture (p = 0.14). Additional analysis showed that there was no significant difference on the sensations evoked by different treatment modalities.

Conclusion

These findings support VGAIT as a promising method for pain management.

Characterizing the analgesic effects of real and imagined acupuncture using functional and structure MRI

Acupuncture and imagery interventions for pain management have a long history. The present study comparatively investigated whether acupuncture and video-guided acupuncture imagery treatment (VGAIT, watching a video of acupuncture on the participant's own body while imagining it being applied) could modulate brain regional connectivity to produce analgesic effects. The study also examined whether pre-intervention brain functional and structural features could be used to predict the magnitude of analgesic effects. Twenty-four healthy participants were recruited and received four different interventions (real acupuncture, sham acupuncture, VGAIT, and VGAIT control) in random order using a cross-over design. Pain thresholds and magnetic resonance imaging (MRI) data were collected before and after each intervention. We first compared the modulatory effects of real acupuncture and VGAIT on intra- and inter-regional intrinsic brain connectivity and found that real acupuncture decreased regional homogeneity (ReHo) and functional connectivity (FC) in sensorimotor areas, whereas VGAIT increased ReHo in basal ganglia (BG) (i.e., putamen) and FC between the BG subcortical network and default mode network. The altered ReHo and FC were associated with changes in pain threshold after real acupuncture and VGAIT, respectively. A multimodality fusion approach with pre-intervention ReHo and gray matter volume (GMV) as features was used to explore the brain profiles underlying individual variability of pain threshold changes by real acupuncture and VGAIT. Variability in acupuncture responses was associated with ReHo and GMV in BG, whereas VGAIT responses were associated with ReHo and GMV in the anterior insula. These results suggest that, through different pathways, both real acupuncture and VGAIT can modulate brain systems to produce analgesic effects.

Anxiety and Osteoarthritis Disability: Updated Overview and Commentary

Introduction:

Osteoarthritis, a widespread highly painful often incapacitating joint disease continues to impose immense personal and societal challenges among adults of all ages, especially among older adults. In the absence of any effective cure or treatment, it has become essential to explore all correlates of this chronic disabling disease, especially those that might be preventable or modifiable. Anxiety, a potentially remediable state of mental distress - found linked to chronically disabling forms of arthritis, in various imperceptible ways, and which may have an immense bearing on the outcomes of osteoarthritis, has not received as much attention in the related literature as other topics, such as surgery.

Objective:

In line with previous promising work, this narrative review elected to explore the extent to which current researchers in the field are pursuing this topic, and if so, the degree to which prevailing peer-reviewed data sources support an important role for continued research in this realm, and in what regard.

Methods:

Primarily explored were the key databases housing relevant publications that emerged over Aug 1, 2018-Feb 26, 2020 using the keywords Osteoarthritis and Anxiety. Using a descriptive approach, the relative progress made over the past five previous years in this regard was assessed, in addition to what joints have been studied and with what frequency, and how the degree of interest compares to other currently researched osteoarthritis themes. The potential for intervening in the osteoarthritis pain cycle by addressing anxiety was also examined.

Results:

Findings show a high level of current interest in this topic, and that despite the paucity of prospective studies, studies on joints other than the knee and hip joints, some equivocal conclusions, small numbers of anxiety-related studies compared to other topics, and substantive design limitations, it appears that future research in this realm is strongly indicated.

Conclusion:

This topic if examined further is likely to produce highly advantageous results at all stages of the osteoarthritic disease process and in the context of primary, secondary, as well as tertiary measures to ameliorate osteoarthritis pain and disability.

Restoring body image after cancer (ReBIC): A group therapy intervention

OBJECTIVES

Body image (BI) remains a significant survivorship challenge among breast cancer (BC) survivors. We describe an 8-week group intervention-restoring body image after cancer (ReBIC)-developed to target BI distress for BC survivors.

METHODS

The intervention was informed by interviews with BC survivors and by a descriptive, exploratory approach which adapted guided imagery exercises to address BI. Educational material was selected to address sociocultural factors that may contribute to BI distress and affect adjustment. Videotape reviews and content analyses further refined the intervention.

RESULTS

The intervention incorporates three active components: psychotherapeutic group principles; guided imagery exercises to address BI; and psychoeducation on relevant socialization factors and gender-based messages internalized by women in Western society. The therapeutic group was a supportive and effective way to assist BC survivors to gain insight on BI impacts, their histories, and relevant sociocultural factors contributing to BI distress. The group also facilitated the working through of grief over multiple losses. Guided imagery was well-received, and appeared to help survivors identify negative and emerging self-schema, as well as facilitate new self-views. Specific themes included negative emotions associated with an altered body and self, grief and loss, isolation, difficulties with sexual intimacy, relationship challenges, and uncertainty around sense of self and future.

CONCLUSION

An empirically tested group therapy intervention is described and has implications for survivorship programs to help address BI-related challenges. Future work could consider testing a similar approach tailored for other cancer populations.

Benefits of a Home Treatment Program Using Guided Imagery Relaxation Based on Audio Recordings for People With Fibromyalgia

Despite the plethora of treatments available for patients with fibromyalgia, there is insufficient evidence to date as to what the ideal treatment approach is. This study sought to determine the effectiveness of a home program of audio-recorded guided imagery relaxation on people with fibromyalgia. This experimental 8-week longitudinal trial design was undertaken with 60 people diagnosed with fibromyalgia who were randomly assigned to either a guided imagery intervention group or a control group. Pain at tender points, anxiety, self-efficacy, quality of sleep, quality of life, and the impact of the fibromyalgia were determined at baseline, at 4 weeks, and at 8 weeks. After the guided imagery intervention, we found significant differences regarding trait anxiety, sleep quality, and tenderness at some of the tender points. There is a need, therefore, to develop and evaluate interventions that may enhance the quality of life of those affected by this disorder.

Evidence-Based Nonpharmacologic Strategies for Comprehensive Pain Care: The Consortium Pain Task Force White Paper

Medical pain management is in crisis; from the pervasiveness of pain to inadequate pain treatment, from the escalation of prescription opioids to an epidemic in addiction, diversion and overdose deaths. The rising costs of pain care and managing adverse effects of that care have prompted action from state and federal agencies including the DOD, VHA, NIH, FDA and CDC. There is pressure for pain medicine to shift away from reliance on opioids, ineffective procedures and surgeries toward comprehensive pain management that includes evidence-based nonpharmacologic options. This White Paper details the historical context and magnitude of the current pain problem including individual, social and economic impacts as well as the challenges of pain management for patients and a healthcare workforce engaging prevalent strategies not entirely based in current evidence. Detailed here is the evidence-base for nonpharmacologic therapies effective in postsurgical pain with opioid sparing, acute non-surgical pain, cancer pain and chronic pain. Therapies reviewed include acupuncture therapy, massage therapy, osteopathic and chiropractic manipulation, meditative movement therapies Tai chi and yoga, mind body behavioral interventions, dietary components and self-care/self-efficacy strategies. Transforming the system of pain care to a responsive comprehensive model necessitates that options for treatment and collaborative care must be evidence-based and include effective nonpharmacologic strategies that have the advantage of reduced risks of adverse events and addiction liability. The evidence demands a call to action to increase awareness of effective nonpharmacologic treatments for pain, to train healthcare practitioners and administrators in the evidence base of effective nonpharmacologic practice, to advocate for policy initiatives that remedy system and reimbursement barriers to evidence-informed comprehensive pain care, and to promote ongoing research and dissemination of the role of effective nonpharmacologic treatments in pain, focused on the short- and long-term therapeutic and economic impact of comprehensive care practices.

Guided imagery targeting exercise, food cravings, and stress: a multi-modal randomized feasibility trial

The purpose of this randomized wait-list controlled trial was to test the feasibility and preliminary efficacy of a guided imagery based multi-behavior intervention intended to address psychological stress, food cravings, and physical activity. Personalized guided imagery scripts were created and participants were instructed to practice guided imagery every day for 35 consecutive days. Of 48 women who enrolled, we report comparisons between 16 randomized to treatment with 19 who were wait-listed (overall Mage = 45.50; Mbodymassindex = 31.43). Study completers reported 89% compliance with practicing guided imagery during the intervention. A significant time-by-group interaction was observed with reductions in food cravings and increases in physical activity compared with wait-list controls. Telephone-based multi-behavior interventions that utilize guided imagery to address food cravings and exercise behavior appear to be acceptable for overweight and obese women. Future phone-based guided imagery research testing this skill to address multiple health behaviors is justified.

A Scoping Review of Health Outcomes Examined in Randomized Controlled Trials Using Guided Imagery

INTRODUCTION

Guided imagery involves the controlled visualization of detailed mental images. This integrative health technique is used for healing, health maintenance, or the treatment of specific conditions. Guided imagery is an integral part of mindfulness meditation, hypnosis, and various relaxation exercises. However, evidence to support the widespread use and dissemination of guided imagery interventions has been lacking. The purposes of this scoping review were to document the scope of health outcomes and disease processes examined by guided imagery researchers and the journal outlets where this work has been published. Secondary purposes were to review the efficacy of guided imagery, risk of bias from studies published in selected integrative health journals, and gain feedback from clinicians in a practiced-based research network (PBRN) about potential barriers for use in clinical settings.

METHODS

Ten bibliographic databases were searched for randomized controlled trials (RCTs) published between 1960 and 2013 that included adult participants. Descriptive and analytic methods were employed to document the journal outlets, diseases, and health outcomes investigated.

RESULTS

320 RCTs that included more than 17,979 adult participants were reviewed. The published studies appeared in 216 peer-reviewed journals from diverse disciplines largely representing psychology, the sport sciences, rehabilitation, nursing, and medicine. Major outcomes observed were coping with pain, stroke recovery, anxiety, coping with stress, and sport skills. Practitioner feedback from the PBRN revealed some interest but skepticism and time constraints were discussed as barriers.

CONCLUSIONS

Ongoing research and creative dissemination techniques are warranted.
