Veterans' Insights on Heart Rate Variability Biofeedback to Treat Fibromyalgia-Related Pain.

BACKGROUND: Heart rate variability biofeedback (HRVB) is a self-management strategy that guides individuals to breathe at a designated resonance frequency of the cardiovascular system. Resonant breathing may reduce FM-related symptoms as well as improve physical functioning and quality of life. Although prior research recommends HRVB for chronic pain, we found no studies testing the feasibility for individuals with FM regarding protocol adherence or acceptability of the treatment. AIMS: To determine the feasibility and acceptability of a heart rate variability biofeedback (HRVB) protocol in a group of Veterans with fibromyalgia (FM). DESIGN: A multi-method feasibility and acceptability study. SETTINGS: A Veterans Health outpatient pain medicine clinic. PARTICIPANTS/SUBJECTS: We enrolled 7 women and 3 men between the ages of 33 and 68 years with a diagnosis of FM. METHODS: We enrolled 10 veterans in a HRVB study using a recommended protocol to treat FM. Veterans were given a HRVB device, emWave2, and instructed to practice at home twice daily for 20 minutes per session. Following a 7-week intervention period, we conducted an end of study focus group. We used content analysis to develop themes to determine the feasibility of engaging in HRVB and adhering to the intervention protocol, as well as insights of veterans about the intervention. RESULTS: Three common themes emerged: intervention implementation, protocol adherence, and self-awareness. CONCLUSIONS: Results of this study suggest difficulties operating the emWave2 and scheduling challenges interfered with HRVB implementation. However, veterans reported self-awareness of the benefits of HRVB, positive physiological effects, and improved psychological effects. Future studies require a larger sample size to provide a deeper insight.

Heart Rate Variability Biofeedback to Treat Fibromyalgia: An Integrative Literature Review.

OBJECTIVES: Fibromyalgia (FM) is associated with debilitating pain and a reduced heart rate variability (HRV), reflecting decreased emotional adaptability and resistance to stress. Common pharmacological treatments are ineffective, and opioids are highly addictive and cause an estimated 15,000 overdose deaths per year. Effective recommendations include patient-centered interventions like physical activity, cognitive behavioral therapy, and biofeedback. Heart rate variability biofeedback (HRVB) may be effective in improving HRV, thus increasing stress resistance and emotional adaptability and reducing pain. DESIGN: This integrative literature review was conducted to examine the relationship between HRVB and FM-related chronic pain using the Theory of Symptom Self-Management and to identify available HRVB technology. DATA SOURCES: We searched PubMed, EBSCOhost, and Google Scholar electronic databases for relevant publications. Manuscripts were selected using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses strategy, and study quality was assessed using the Critical Appraisal Skills Programme guidelines. The relationship between HRVB and FM was analyzed and evaluated based on the methodological framework proposed by Whittemore and Knafl. REVIEW/ANALYSIS METHODS: We reviewed 22 articles and included six in this review. Five reported HRVB as a treatment for chronic pain, and one for FM pain. RESULTS: Overall, the articles in this review support the claim that HRVB is related to decreased pain. The researchers evaluated five HRVB programs, three on handheld devices and two on desktop computers. CONCLUSIONS: The reviewed studies had methodological flaws. However, HRVB is a promising treatment for chronic pain. Larger, randomized controlled studies are needed to thoroughly evaluate the relationship between HRVB and FM pain.

A Scoping Review of Measures Utilized to Assess Patient Satisfaction with Acupuncture Treatments Within Randomized Controlled Trials.

Objective: Patient satisfaction is an increasing priority for health care facilities in ensuring reimbursement for services, high-quality access to care, and transparent communication. Cumulatively, these metrics guide patient-centered care and facilitate optimal service delivery. The purpose of this scoping review was to evaluate measures of patient satisfaction with acupuncture treatments. Materials and Methods: This scoping review was guided by the Arksey and O'Malley methodological framework. Analysis was performed based on the multidimensional hierarchical model of perceived service-quality conceptual framework. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement was used to organize included publications and to display search processes in a flow diagram. An academic reference librarian conducted a literature search, using electronic databases that included PubMed,® Cumulative Index to Nursing and Allied Health Literature, EMBASE,® and Web of Science. Results: A total of 384 publications were initially identified and screened; 26 met the eligibility criteria and were included in the synthesis. Discrepancies in the use of patient-satisfaction measures among studies were found in only 1 study demonstrating holistic assessment. Conclusions: There is a need for consistent measurement of patient satisfaction with acupuncture treatments. Future studies may evaluate development of a satisfaction tool to measure patient satisfaction with acupuncture treatments comprehensively.

Feasibility and Acceptability of Heart Rate Variability Biofeedback in a Group of Veterans with Fibromyalgia.

Objectives: To determine the feasibility and acceptability of a heart rate variability biofeedback (HRVB) protocol in a focus group of Veterans with fibromyalgia (FM). Design: A multimethod feasibility and acceptability study. Settings/location: A Veterans Health outpatient pain medicine clinic in the southern United States. Subjects: The researcher enrolled seven women and three men between the ages of 33 and 68 years with a diagnosis of FM. Interventions: Participants practiced HRVB on the emWave2 at home for 20 min twice daily for 7 weeks. Outcome measures: Feasibility to adhere to the HRVB protocol was measured using the practice frequency and time (minutes) data collected from the emWave2. The author compared the individual reports from participants with the Credibility/Expectancy Questionnaire to measure the acceptability of the intervention. In addition, the principal investigator evaluated data from the Short-form McGill Pain Questionnaire (SFMQ) and the Revised Fibromyalgia Impact Questionnaire (FIQR) at the baseline and weekly study visits for a signal of efficacy for pain control, functional status, and quality of life (QOL). Results: The majority of participants (80%) expected 50% or more improvement in their pain, and (70%) felt HRVB would reduce their FM-related pain by 50%-80%. The mean daily practice frequency rate was 0.80. The mean practice duration was 19.36 min. Pain score differences from the SFMQ were insignificant preintervention and postintervention. The mean total FIQR scores postintervention improved by 18.1 points. Conclusions: Findings suggest twice-daily HRVB practice protocol is not feasible. However, 20-min HRVB sessions were feasible and acceptable. Improved FIQR scores post-treatment suggest HRVB may be an effective strategy to improve functional status and QOL for Veterans with FM.
