BACKGROUND: Hypertension occurs in nearly 10 percent of pregnancies, and is associated with higher risk of infant and maternal morbidity and mortality than in normal pregnancies. Previous studies have suggested that relaxation therapies reduce blood pressure in nonpregnant adults. The objectives of this pilot randomized trial were to provide preliminary evidence of whether relaxation by means of guided imagery would reduce blood pressure in hypertensive pregnant women, and to assess the feasibility of a larger trial.
METHODS: A total of 69 pregnant women with hypertension were randomized to periods of guided imagery or of quiet rest, twice daily for 4 weeks or until delivery, whichever came first. Daytime ambulatory mean arterial pressure, systolic and diastolic blood pressure, and anxiety were measured weekly for up to 4 weeks.
RESULTS: Women allocated to guided imagery had lower mean arterial pressure elevations over time than those allocated to quiet rest (guided imagery: M = 1.58 mmHg, SD = 7.63; quiet rest: M = 5.93 mmHg, SD = 6.55; t = 2.36, p = 0.02). However, when adjusted for baseline mean arterial pressure and gestation, the effect was not significant (p = 0.14). Numbers of women prescribed antihypertensive medication postrandomization were similar (guided imagery: n = 16; quiet rest: n = 13, χ(2) = 0.74, p = 0.46). There was also no evidence of an effect on women's anxiety. Nearly 90 percent (n = 26) of the guided imagery group indicated that they would use it again.
CONCLUSIONS: Further rigorous study is warranted to determine effects of guided imagery on maternal blood pressure and perinatal health outcomes.

Relaxation and guided imagery in Hispanic persons diagnosed with fibromyalgia: a pilot study.
Fam Community Health. 2008 Jul-Sep;31(3):204-12. PMID: 18552601

Fibromyalgia (FM) is a chronic pain disorder affecting 2% of the population in the United States. Another 16 million Hispanics suffer from generically identified rheumatic diseases that likely include FM. Because there are few reported studies of Hispanics with FM, a pilot study using a repeated-measures pretest-posttest design investigated the effects of a 10-week mind-body intervention (visual imagery with relaxation) on symptom management. The change in means from baseline to week 10 demonstrated improvement in self-efficacy for managing pain and other symptoms and functional status. Visual imagery with relaxation is a mind-body intervention that may be used for symptom management in this population.

INTRODUCTION: In the United States, more than 1 million women and men are affected with interstitial cystititis (IC), which is a clinical syndrome involving urinary urgency, frequency, and pelvic pain. A review of the literature revealed that there are no studies showing the effect of guided imagery in women with IC. The purpose of this clinical investigation was to explore the effect of guided imagery on pelvic pain and urinary symptoms in women with IC symptoms.
METHODOLOGY: Thirty (30) women with diagnosed IC were randomized into 2 equal groups. One group (treatment) listened to a 25-minute guided imagery compact disc (CD), that was created specifically for women with pelvic pain and IC, twice a day for 8 weeks. The control group rested for 25 minutes twice daily for 8 weeks. Because no guided imagery CDs specifically for women with IC were found on the commercial market, the authors created a script and recorded the CD specifically for women with IC and pelvic pain. The focus of this guided imagery CD was on healing the bladder, relaxing the pelvic-floor muscles, and quieting the nerves specifically involved in IC. Baseline and end-of-study assessment questionnaires (Interstitial Cystitis Symptom Index&Problem Index [IC-SIPI], IC Self-Efficacy Scale, a visual analogue [VAS] scale for pain, and a global response assessment [GRA]), 2-day voiding diaries, and 24-hour pain diaries were completed by the subjects and were evaluated using SPSS (Chicago, IL).
RESULTS: More than 45% of the treatment group were responders to guided imagery therapy noting a moderate or marked improvement on the GRA. Pain scores and episodes of urgency significantly decreased in the treatment group. Responders had significant reductions in IC-SIPI scores (problem index, p = 0.006; symptom index, p = 0.004). In addition, responders on the GRA had significant (p = 0.039) improvements in mean pain scores from 5.50 to 2.57 at the end of the study in contrast to the nonresponders, whose pain levels remained the same (4.89 to 4.39).
CONCLUSIONS: This is the first study providing preliminary data supporting the use of guided imagery as a potential therapy for IC. Guided imagery may be a useful tool to offer women with IC for pain and IC symptom management. It is an intervention without negative side-effects, is readily available, and shows a trend toward improvement of IC symptoms.

OBJECTIVES: (1) To investigate the effects of a 6-week intervention of guided imagery on pain level, functional status, and self-efficacy in persons with fibromyalgia (FM); and (2) to explore the dose-response effect of imagery use on outcomes.
DESIGN: Longitudinal, prospective, two-group, randomized, controlled clinical trial.
SETTING AND SUBJECTS: The sample included 48 persons with FM recruited from physicians' offices and clinics in the mid-Atlantic region.
INTERVENTION: Participants randomized to Guided Imagery (GI) plus Usual Care intervention group received a set of three audiotaped guided imagery scripts and were instructed to use at least one tape daily for 6 weeks and report weekly frequency of use (dosage). Participants assigned to the Usual Care alone group submitted weekly report forms on usual care.
MEASURES: All participants completed the Short-Form McGill Pain Questionnaire (SF-MPQ), Arthritis Self- Efficacy Scale (ASES), and Fibromyalgia Impact Questionnaire (FIQ), at baseline, 6, and 10 weeks, and submitted frequency of use report forms.
RESULTS: FIQ scores decreased over time in the GI group compared to the Usual Care group (p = 0.03). Ratings of self-efficacy for managing pain (p = 0.03) and other symptoms of FM also increased significantly over time (p =<0.01) in the GI group compared to the Usual Care group. Pain as measured by the SF-MPQ did not change over time or by group. Imagery dosage was not significant.
CONCLUSIONS: This study demonstrated the effectiveness of guided imagery in improving functional status and sense of self-efficacy for managing pain and other symptoms of FM. However, participants' reports of pain did not change. Further studies investigating the effects of mind-body interventions as adjunctive self-care modalities are warranted in the fibromyalgia patient population.

For the past several decades, papers in the nursing literature have advocated the use of cognitive interventions in clinical practice. Increasing consumer use of complementary therapies, a cost-driven health care system, and the need for evidence-based practice all lend urgency to the validation of the efficacy of these interventions. This review focuses specifically on guided imagery intervention studies identified in the nursing, medical and psychological literature published between 1966 and 1998. Included were 46 studies of the use of guided imagery for management of psychological and physiological symptoms. There is preliminary evidence for the effectiveness of guided imagery in the management of stress, anxiety and depression, and for the reduction of blood pressure, pain and the side effects of chemotherapy. Overall, results of this review demonstrated a need for systematic, well-designed studies, which explore several unanswered questions regarding the use of guided imagery. These include the effects of different imagery language, symptoms for which guided imagery is effective, appropriate and sensitive outcome measures, method of delivery of the intervention and optimum dose and duration of the intervention, and individual factors that influence its effectiveness.

Prospective memory intervention using visual imagery in individuals with brain injury.
Neuropsychol Rehabil. 2019 Mar;29(2):289-304

Prospective memory deficits are common after brain injury and can create impediments to independent living. Most approaches to management of such deficits are compensatory, such as the use of notebooks or electronic devices. While these can be effective, a restorative approach, in theory, could lead to greater generalisation of treatment. In the current study a metacognitive technique, using visual imagery, was employed under conditions of rote repetition and spaced retrieval. Treatment was provided in an AB-BA crossover design with A as the active treatment and B as a no-treatment attention control to 20 individuals with brain injury. A group of 20 healthy participants served to control for effects of re-testing. Individuals with brain injury demonstrated improvement on the main outcome measure of prospective memory, the Memory for Intentions Screening Test, only after the active treatment condition. In addition, some generalisation of treatment was measured in daily life. Moreover, treatment gains were maintained for one year after treatment was completed.

Electroencephalographic Motor Imagery Brain Connectivity Analysis for BCI: A Review.
Neural Comput. 2016 06;28(6):999-1041
Authors: Hamedi M, Salleh ShH, Noor AM
Recent research has reached a consensus on the feasibility of motor imagery brain-computer interface (MI-BCI) for different applications, especially in stroke rehabilitation. Most MI-BCI systems rely on temporal, spectral, and spatial features of single channels to distinguish different MI patterns. However, no successful communication has been established for a completely locked-in subject. To provide more useful and informative features, it has been recommended to take into account the relationships among electroencephalographic (EEG) sensor/source signals in the form of brain connectivity as an efficient tool of neuroscience. In this review, we briefly report the challenges and limitations of conventional MI-BCIs. Brain connectivity analysis, particularly functional and effective, has been described as one of the most promising approaches for improving MI-BCI performance. An extensive literature on EEG-based MI brain connectivity analysis of healthy subjects is reviewed. We subsequently discuss the brain connectomes during left and right hand, feet, and tongue MI movements. Moreover, key components involved in brain connectivity analysis that considerably affect the results are explained. Finally, possible technical shortcomings that may have influenced the results in previous research are addressed and suggestions are provided.
