Feasibility trial of guided imagery and control interventions in mock subjects

Effect of Guided Imagery on Pain and Health-Related Quality of Life in Musculoskeletal Medicine: a Comprehensive Narrative Review

PURPOSE OF REVIEW

Guided imagery (GI) is a non-pharmacological method used to reduce pain, stress, and anxiety. No comprehensive review has yet investigated the application of GI in musculoskeletal medicine, its various types, and potential mechanisms. The aim of this comprehensive narrative review was to examine the types of GI used in musculoskeletal medicine and GI effect on pain and health-related quality of life.

RECENT FINDINGS

A comprehensive narrative review of the English language scientific literature. PubMed, Google Scholar, ProQuest, and PEDro databases were searched from inception until August 2020 using keywords related to GI, musculoskeletal disorders, pain, and health-related quality of life. The search results generated 133 articles. After a critical analysis, 12 publications were included in this review. GI characteristics and protocols varied significantly between studies. Based on the reviewed studies, we advocate GI as a safe, non-invasive technique that can assist in managing pain, depression, stress, fatigue, anxiety, reducing medication use, improving general well-being, wellness, and quality of life in patients with musculoskeletal disorders. We recommend further investigations of GI mechanisms.

Guided Imagery for Total Knee Replacement: Responses to an Audiobook Placebo Treatment

The use of a placebo is the gold standard for establishing the efficacy of new treatments in randomized controlled trials (RCTs). Placebo treatments are inert; this allows specific effects of the experimental treatment to be separated from nonspecific physiological, psychological, and social effects. The aim of this study was to scrutinize the workings of an audiobook (AB) placebo treatment, which was used in a placebo-controlled, investigator-blinded, RCT of the effect of guided imagery (GI) to improve pain and function in persons undergoing total knee replacement. A secondary analysis of quantitative and narrative data collected during the RCT was performed. The AB treatment provided attention control. Participants in the AB group identified benefits-pleasant get-away, new knowledge, quiet time-out, and inspiration; however, there was also evidence of resentful demoralization, especially in the postoperative period. The use of ABs as a placebo treatment in GI RCTs should be executed with caution.

Guided Imagery for Total Knee Replacement: A Randomized, Placebo-Controlled Pilot Study

OBJECTIVES

To determine the effect of guided imagery (GI) on functional outcomes of total knee replacement (TKR), explore psychological and neuroimmune mediators, and assess feasibility of study implementation.

DESIGN

Investigator-blinded, randomized, placebo-controlled pilot study.

SETTINGS

Hospital, surgeon's office, participant's home.

PARTICIPANTS

82 persons undergoing TKR.

INTERVENTIONS

Audiorecordings of TKR-specific GI scripts or placebo-control audiorecordings of audiobook segments.

OUTCOME MEASURES

Gait velocity and Western Ontario and McMaster Universities Arthritis Index (WOMAC) Function scale.

RESULTS

Outcomes for 58 participants (29 receiving GI and 29 controls) were analyzed at 6 months after surgery. The most frequent reason for noncompletion was protocol-driven exclusion at 6 months for having the contralateral knee replaced before the study endpoint (n = 15). With imaging ability as a moderator, gait velocity, but not WOMAC Function score, was significantly improved at 6 months in the GI group. Participants in the GI group, but not the control group, had lower WOMAC Pain scores at 3 weeks after surgery than at baseline. Hair cortisol concentration was significantly lower at 6 months after surgery than at baseline in the GI group but not the control group. GI group participants had lower treatment adherence but greater treatment credibility than the control group.

CONCLUSION

Randomized controlled trials of GI in the TKR population are feasible, but inclusion/exclusion criteria influence attrition. Further studies are needed to elaborate this study's findings, which suggest that guided imagery improves objective, but not patient-reported, outcomes of TKR. Hair cortisol concentration results suggest that engagement in a time-limited guided imagery intervention may contribute to stress reduction even after the intervention is terminated. Further investigation into optimal content and dosing of GI is needed.

Perceptions of guided imagery for stress management in pregnant African American women

Maternal stress during pregnancy has been associated with numerous adverse pregnancy, birth, and health outcomes. Pregnant African American women have been reported to have higher levels of stress compared to other ethnic or racial groups underscoring the need for effective interventions to reduce stress in this population. The purpose of this study was to gain an in-depth understanding of the perceptions of guided imagery (GI) as a technique for stress management in a cohort of pregnant African American women who participated in a GI intervention as part of a larger mixed methods randomized controlled trial. The 12week intervention was a professionally recorded compact disc with four tracks developed and sequenced to reduce stress and associated symptoms. The findings from this descriptive phenomenologic study were derived from daily logs and interviews from 36 participants randomized to the GI group. Participants described the stressful nature of their lives. Results demonstrated pregnant African American women perceived the intervention as beneficial in reducing stress and the associated symptoms. The emergent themes suggested the intervention offered a respite from their stressful lives, reduced the negative emotional responses to stress and enhanced well-being, benefited other areas of their daily life, and provided an opportunity to connect with their baby. The study results support the perceived efficacy of GI as a stress coping intervention. GI is an economic as well as easy to implement, access and use technique that has potential stress coping benefits as perceived by pregnant African American women.
