Impact of self-administered relaxation and guided imagery techniques during final trimester and birth

Effectiveness of mind-body interventions in labour pain management during normal delivery: A systematic review and meta-analysis

BACKGROUND

Labour pain is a common experience among women and poses risks to both the mother and neonate. Mind-body interventions have demonstrated effectiveness in diverse contexts, but their effectiveness in labour pain management remains controversial.

OBJECTIVE

To identify the effects of each category of mind-body interventions on labour pain management, particularly pain intensity; the use of pharmacological pain relief medications; and the consequent outcomes, including the rate of caesarean section, duration of labour, and fear of childbirth.

DESIGN

Systematic review and meta-analysis.

METHODS

A systematic search for related articles was conducted in 10 databases. Randomised controlled trials focusing on the effectiveness of mind-body interventions in labour pain management were included. Two researchers independently conducted methodological quality assessments, data extraction and grading the evidence. Meta-analyses were conducted when studies measured the same outcomes. Standardised mean differences were calculated for continuous variables, whilst risk ratios were calculated for dichotomous variables. All analyses were performed using RevMan version 5.3.

RESULTS

A total of 25 studies from 24 trials were included, and six categories of mind-body interventions, namely hypnosis, mindfulness, breathing skills, muscle relaxation techniques, guided imagery, and therapeutic touch, were identified. Specifically, hypnosis and mindfulness might be effective in relieving labour pain intensity, with large effect sizes (SMD: -1.45, 95 % confidence interval [CI] -2.34, -0.55, I2 = 91 %; SMD: -1.22, 95 % CI -2.07, -0.37, I2 = 93 %, respectively), but could not reduce the use of epidural analgesia. Mindfulness, in particular, yielded statistically significant reductions in the rate of caesarean section, with a small effect size (RR: 0.46, 95 % CI 0.21, 0.97, I2 = 49 %), and in fear of childbirth, with a medium effect size (SMD: -0.63, 95 % CI -1.09, -0.17, I2 = 65 %). Additionally, all categories of mind-body interventions were associated with a significantly decreased duration of labour compared with the control conditions.

CONCLUSIONS

Mind-body interventions may have potential benefits in terms of decreasing labour pain intensity, the rate of caesarean section, the duration of labour, and fear of childbirth, with small-to-large effect sizes. Particularly, hypnosis and mindfulness exhibited significant positive effects in terms of relieving labour pain intensity, with large effect sizes. These interventions could serve as complementary or alternative methods for labour pain management in clinical practice. Nevertheless, further rigorous randomised controlled trials are warranted to confirm our results.

The Effect of Benson Relaxation Technique on Stress, Anxiety, and Depression in Pregnant Women

Relaxation programs can be effective in establishing psychological tranquility for maternal and fetal health. This study was conducted to evaluate the effect of this low-cost, effective, easy method on the stress, anxiety, and depression in pregnant women. This randomized clinical trial study was conducted from July 2015 to July 2016. Seventy pregnant women in the third trimester of pregnancy were included in this study. Participants were randomly assigned to 2 groups of 35 subjects using a random number table. Participants in group 1 received relaxation training and group 2 received routine care. A demographic questionnaire and Depression, Anxiety, and Stress Scale (DASS-21) were completed before and 1 and 2 months after the intervention. The SPSS software version 18 was used for data analysis. There were significant differences in the mean difference of the total DASS score (14; 95% confidence interval [CI]: 4 to 32) as well as the scores of stress (4; 95% CI : 1 to 10), anxiety (6; 95% CI: 2 to 10), and depression (6; 95% CI: 2 to 12) 2 months after the intervention between the 2 groups. The Benson relaxation technique decreased DASS-21 scores in the intervention group.

Construction of Meta-Thinking Educational Program Based on Mental-Brain Simulation (MTMBS) and Evaluating its Effectiveness on Executive Functions, Emotion Regulation, and Impulsivity in Children With ADHD: A Resting-State Functional MRI Study

OBJECTIVE

The aim of present research was to make a Meta-Thinking educational program based on mental-brain simulation and to evaluate its effectiveness on executive functions, emotion regulation and impulsivity in children with ADHD.

METHODS

The research method was Embedded Design: Embedded Experimental Model. The research sample included 32 children with ADHD who were randomly assigned to two experimental and control groups. The intervention was implemented for eight sessions of 1.5 hr for the experimental group, and fMRI images were taken from them, while the control group didn't receive any treatment. Finally, using semi-structured interviews, coherent information was collected from the parents of the experimental group about the changes made. Data were analyzed with SPSS-24, MAXQDA, fMRIprep, and FSL software.

RESULTS

The Meta-Thinking Educational Program had effect on performance of ADHD children and suppressed brain regions related to DMN.

CONCLUSION

The Implementation of this educational program plays a vital role in improving psychological problems of children with ADHD.

Effect of music on labor and delivery in nulliparous singleton pregnancies: a randomized clinical trial

BACKGROUND

Women's experience of pain during labor varies greatly, and pain control is a major concern for obstetricians. Several methods have been studied for pain management for women in labor, including drug and non-drug interventions.

OBJECTIVE

To test the hypothesis that in nulliparous women with singleton pregnancies at term, listening to music would reduce the pain level during labor.

METHODS

Parallel group non-blinded randomized clinical trial conducted at a single center in Italy. Nulliparous women in spontaneous labor with singleton pregnancies and vertex presentation admitted in labor and delivery room between 37 0/7 and 42 0/7 weeks of gestation for active phase of labor were eligible, and were randomized in a 1:1 ratio to receive music during labor or no music during labor. Music in labor was defined listening to music from the randomization until the delivery of the baby. The primary endpoint was the pain level during the active phase of labor, recorded using the visual analogue scale (VAS) for pain, ranging from 0 (no pain) to 10 (unbearable pain). The effect of music use during labor on each outcome was quantified as the mean difference (MD) with 95% confidence interval (CI).

RESULTS

During the study period, 30 women agree to take part in the study, underwent randomization, and were enrolled and followed up. 15 women were randomized in the music group, and 15 in the control group. No patients were lost to follow up for the primary outcome. Pain level during the active phase of labor was scored 8.8 ± 0.9 in the music group, and 9.8 ± 0.3 in the control group (MD - 1.00 point, 95% CI - 1.48 to - 0.52; P < 0.01). Music during labor and delivery was also associated with a decreased pain at 1 h postpartum (MD - 2.40 points, 95% CI - 4.30 to - 0.50), and decreased anxiety level during active phase of labor (MD - 19.90 points, 95% CI - 38.72 to - 1.08), second stage of labor (MD - 49.40 points, 95% CI - 69.44 to - 29.36), and at 1 h postpartum (MD - 27.00 points, 95% CI - 47.37 to - 6.63).

CONCLUSION

In nulliparous women with singleton pregnancies at term, listening to music reduces the pain level, and the anxiety level during labor.

Building Wellbeing in People With Chronic Conditions: A Qualitative Evaluation of an 8-Week Positive Psychotherapy Intervention for People Living With an Acquired Brain Injury

Research indicates that Acquired Brain Injury (ABI) is associated with significant and chronic impairment across multiple areas of functioning including physical, cognitive, emotional and behavioral domains. Whilst impairments associated with ABI can be ameliorated, cure is seldom possible. The emergence of positive psychology reflects a paradigm shift in health and wellbeing research, highlighting the role of character strengths, positive emotions, meaning, and resilience. Positive psychology interventions have been demonstrated to improve wellbeing in a variety of populations, although research investigating the impact of positive psychotherapy for people living with ABI are sparse. Here we characterize the experience of an 8-week positive psychotherapy intervention for 13 people living with ABI including four mentors and nine participants using thematic analysis of transcripts collected during mini-groups and one-to-one interviews. Six main themes were identified including empowerment, social opportunity, coping, cultivation of positive emotion, consolidation of skills and barriers. Results indicated that wellbeing can be promoted and improved in individuals with ABI. Recent theoretical developments in wellbeing science highlight scope to improve the intervention by connecting individuals to their communities and spending time in nature.

Guided imagery for treating hypertension in pregnancy

BACKGROUND

Hypertension (high blood pressure) in pregnancy carries a high risk of maternal morbidity and mortality. Although antihypertensive drugs are commonly used, they have adverse effects on mothers and fetuses. Guided imagery is a non-pharmacological technique that has the potential to lower blood pressure among pregnant women with hypertension. Guided imagery is a mind-body therapy that involves the visualisation of various mental images to facilitate relaxation and reduction in blood pressure.

OBJECTIVES

To determine the effect of guided imagery as a non-pharmacological treatment of hypertension in pregnancy and its influence on perinatal outcomes.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, and two trials registers (October 2018). We also searched relevant conference proceedings and journals, and scanned the reference lists of retrieved studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs). We would have included RCTs using a cluster-randomised design, but none were identified. We excluded quasi-RCTs and cross-over trials.We sought intervention studies of various guided imagery techniques performed during pregnancy in comparison with no intervention or other non-pharmacological treatments for hypertension (e.g. quiet rest, music therapy, aromatherapy, relaxation therapy, acupuncture, acupressure, massage, device-guided slow breathing, hypnosis, physical exercise, and yoga).

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed the trials for inclusion, extracted data, and assessed risk of bias for the included studies. We checked extracted data for accuracy, and resolved differences in assessments by discussion. We assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We included two small trials (involving a total of 99 pregnant women) that compared guided imagery with quiet rest. The trials were conducted in Canada and the USA. We assessed both trials as at high risk of performance bias, and low risk of attrition bias; one trial was at low risk for selection, detection, and reporting bias, while the other was at unclear risk for the same domains.We could not perform a meta-analysis because the two included studies reported different outcomes, and the frequency of the intervention was slightly different between the two studies. One study performed guided imagery for 15 minutes at least twice daily for four weeks, or until the baby was born (whichever came first). In the other study, the intervention included guided imagery, self-monitoring of blood pressure, and thermal biofeedback-assisted relaxation training for four total hours; the participants were instructed to practice the procedures twice daily and complete at least three relief relaxation breaks each day. The control groups were similar - one was quiet rest, and the other was quiet rest as bed rest.None of our primary outcomes were reported in the included trials: severe hypertension (either systolic blood pressure of 160 mmHg or higher, or diastolic blood pressure of 110 mmHg or higher); severe pre-eclampsia, or perinatal death (stillbirths plus deaths in the first week of life). Only one of the secondary outcomes was measured.Low-certainty evidence from one trial (69 women) suggests that guided imagery may make little or no difference in the use of antihypertensive drugs (risk ratio 1.27, 95% confidence interval 0.72 to 2.22).

AUTHORS' CONCLUSIONS

There is insufficient evidence to inform practice about the use of guided imagery for hypertension in pregnancy.The available evidence for this review topic is sparse, and the effect of guided imagery for treating hypertension during pregnancy (compared with quiet rest) remains unclear. There was low-certainty evidence that guided imagery made little or no difference to the use of antihypertensive drugs, downgraded because of imprecision.The two included trials did not report on any of the primary outcomes of this review. We did not identify any trials comparing guided imagery with no intervention, or with another non-pharmacological method for hypertension.Large and well-designed RCTs are needed to identify the effects of guided imagery on hypertension during pregnancy and on other relevant outcomes associated with short-term and long-term maternal and neonatal health. Trials could also consider utilisation and costs of health service.

Relaxation techniques for pain management in labour

BACKGROUND

Many women would like to avoid pharmacological or invasive methods of pain management in labour and this may contribute to the popularity of complementary methods of pain management. This review examined currently available evidence on the use of relaxation therapies for pain management in labour. This is an update of a review first published in 2011.

OBJECTIVES

To examine the effects of mind-body relaxation techniques for pain management in labour on maternal and neonatal well-being during and after labour.

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register (9 May 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 5 2017), MEDLINE (1966 to 24 May 2017), CINAHL (1980 to 24 May 2017), the Australian New Zealand Clinical Trials Registry (18 May 2017), ClinicalTrials.gov (18 May 2017), the ISRCTN Register (18 May 2017), the WHO International Clinical Trials Registry Platform (ICTRP) (18 May 2017), and reference lists of retrieved studies.

SELECTION CRITERIA

Randomised controlled trials (including quasi randomised and cluster trials) comparing relaxation methods with standard care, no treatment, other non-pharmacological forms of pain management in labour or placebo.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We attempted to contact study authors for additional information. We assessed evidence quality with GRADE methodology.

MAIN RESULTS

This review update includes 19 studies (2519 women), 15 of which (1731 women) contribute data. Interventions examined included relaxation, yoga, music and mindfulness. Approximately half of the studies had a low risk of bias for random sequence generation and attrition bias. The majority of studies had a high risk of bias for performance and detection bias, and unclear risk of bias for, allocation concealment, reporting bias and other bias. We assessed the evidence from these studies as ranging from low to very low quality, and therefore the effects below should be interpreted with caution.RelaxationWe found that relaxation compared to usual care provided lowered the intensity of pain (measured on a scale of 0 to 10 with low scores indicating less pain) during the latent phase of labour (mean difference (MD) -1.25, 95% confidence interval (CI) -1.97 to -0.53, one trial, 40 women). Four trials reported pain intensity in the active phase; there was high heterogeneity between trials and very low-quality evidence suggested that there was no strong evidence that the effects were any different between groups for this outcome (MD -1.08, 95% CI -2.57 to 0.41, four trials, 271 women, random-effects analysis). Very low-quality evidence showed that women receiving relaxation reported greater satisfaction with pain relief during labour (risk ratio (RR) 8.00, 95% CI 1.10 to 58.19, one trial, 40 women), and showed no clear benefit for satisfaction with childbirth experience (assessed using different scales) (standard mean difference (SMD) -0.03, 95% CI -0.37 to 0.31, three trials, 1176 women). For safety outcomes there was very low-quality evidence of no clear reduction in assisted vaginal birth (average RR 0.61, 95% CI 0.20 to 1.84, four trials, 1122 women) or in caesarean section rates (average RR 0.73, 95% CI 0.26 to 2.01, four trials, 1122 women). Sense of control in labour, and breastfeeding were not reported under this comparison.YogaWhen comparing yoga to control interventions there was low-quality evidence that yoga lowered pain intensity (measured on a scale of 0 to 10) with low scores indicating less pain) (MD -6.12, 95% CI -11.77 to -0.47, one trial, 66 women), greater satisfaction with pain relief (MD 7.88, 95% CI 1.51 to 14.25, one trial, 66 women) and greater satisfaction with childbirth experience (MD 6.34, 95% CI 0.26 to 12.42 one trial, 66 women (assessed using the Maternal Comfort Scale with higher score indicating greater comfort). Sense of control in labour, breastfeeding, assisted vaginal birth, and caesarean section were not reported under this comparison.MusicWhen comparing music to control interventions there was evidence of lower pain intensity in the latent phase for women receiving music (measured on a scale of 0 to 10 with low scores indicating less pain) (MD -0.73, 95% CI -1.01 to -0.45, random-effects analysis, two trials, 192 women) and very low-quality evidence of no clear benefit in the active phase (MD -0.51, 95% CI -1.10 to 0.07, three trials, 217 women). Very low-quality evidence suggested no clear benefit in terms of reducing assisted vaginal birth (RR 0.41, 95% CI 0.08 to 2.05, one trial, 156 women) or caesarean section rate (RR 0.78, 95% CI 0.36 to 1.70, two trials, 216 women). Satisfaction with pain relief, sense of control in labour, satisfaction with childbirth experience, and breastfeeding were not reported under this comparison.Audio analgesiaOne trial evaluating audio analgesia versus control only reported one outcome and showed no evidence of benefit in satisfaction with pain relief.MindfulnessOne trial evaluating mindfulness versus usual care found an increase in sense of control for the mindfulness group (using the Childbirth Self-Efficacy Inventory) (MD 31.30, 95% CI 1.61 to 60.99, 26 women). There is no strong evidence that the effects were any different between groups for satisfaction in childbirth, or for caesarean section rate, need for assisted vaginal delivery or need for pharmacological pain relief. No other outcomes were reported in this trial.

AUTHORS' CONCLUSIONS

Relaxation, yoga and music may have a role with reducing pain, and increasing satisfaction with pain relief, although the quality of evidence varies between very low to low. There was insufficient evidence for the role of mindfulness and audio-analgesia. The majority of trials did not report on the safety of the interventions. Further randomised controlled trials of relaxation modalities for pain management in labour are needed. Trials should be adequately powered and include clinically relevant outcomes such as those described in this review.

Service Evaluation of Relaxation Workshops for Pregnant Women

This article reports a service evaluation of "antenatal education on physiology of childbirth and relaxation." A service evaluation was carried out during group class discussion, immediately after the workshops, and following birth. Identified themes in the collected data were (a) my own relaxation, (b) confident, and not afraid, (c) proud of myself, (d) unexpected and feeling in control, and (e) support. Overall, women creatively customized the learned skills and reported feelings of pride and confidence. They reported feeling able to apply relaxation techniques when unexpected situations arise. Support and encouragement from partners and midwives were also valued by women. The evaluation demonstrates the efficacy of designing antenatal education that includes education on physiology of normal birth and relaxation training.

Group psychoeducation with relaxation for severe fear of childbirth improves maternal adjustment and childbirth experience--a randomised controlled trial

BACKGROUND

Previous studies on the treatment of women with fear of childbirth have focused on the delivery mode. Women with fear of childbirth often suffer from anxiety and/or depression, and treatment therefore also needs to target postnatal psychological well-being and the early mother-infant relationship.

METHODS

Three hundred and seventy-one nulliparous women out of 4575 scored ≥100 in prospective screening (Wijma Delivery Expectancy Questionnaire, W-DEQ-A), indicating severe fear of childbirth. These women were randomised to psychoeducative group intervention with relaxation (n = 131; six sessions during pregnancy, one postnatal) or to conventional care (n = 240) by community nurses (referral if necessary). Psycho-emotional and psychosocial evaluations [Edinburgh Postnatal Depression Scale (EPDS), social support, Maternal Adjustment and Attitudes (MAMA), Traumatic Events Scale (TES) and the Wijma Delivery Experience Questionnaire (W-DEQ-B)] were completed twice during pregnancy and/or 3 months postpartum.

RESULTS

Postnatal maternal adjustment (MAMA mean score 38.1 ± 4.3 versus 35.7 ± 5.0, p = 0.001) and childbirth experience (mean W-DEQ-B sum score 63.0 ± 29 versus 73.7 ± 32, p = 0.008) were better in the intervention group compared with controls. In hierarchical regression, social support, participating in intervention, and less fearful childbirth experience predicted better maternal adjustment. The level of postnatal depressive symptoms was significantly lower in the intervention group (mean sum score 6.4 ± 5.4 versus 8.0 ± 5.9 p = 0.04). There were no differences in the frequency of post-traumatic stress symptoms between the groups.

CONCLUSIONS

In nulliparous women with severe fear of childbirth, participation in a targeted psychoeducative group resulted in better maternal adjustment, a less fearful childbirth experience and fewer postnatal depressive symptoms, compared with conventional care.

Interventions (other than pharmacological, psychosocial or psychological) for treating antenatal depression

BACKGROUND

A meta-analysis of 21 studies suggests the mean prevalence rate for depression across the antenatal period is 10.7%, ranging from 7.4% in the first trimester to a high of 12.8% in the second trimester. Due to maternal treatment preferences and potential concerns about fetal and infant health outcomes, diverse non-pharmacological treatment options are needed.

OBJECTIVES

To assess the effect of interventions other than pharmacological, psychosocial, or psychological interventions compared with usual antepartum care in the treatment of antenatal depression.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2013), scanned secondary references and contacted experts in the field to identify other published or unpublished trials.

SELECTION CRITERIA

All published and unpublished randomised controlled trials of acceptable quality evaluating non-pharmacological/psychosocial/psychological interventions to treat antenatal depression.

DATA COLLECTION AND ANALYSIS

Both review authors participated in the evaluation of methodological quality and data extraction. Results are presented using risk ratio (RR) for categorical data and mean difference (MD) for continuous data.

MAIN RESULTS

Six trials were included involving 402 women from the United States, Switzerland, and Taiwan. For most comparisons a single trial contributed data and there were few statistically significant differences between control and intervention groups.In a trial with 38 women maternal massage compared with non-specific acupuncture (control group) did not significantly decrease the number of women with clinical depression or depressive symptomatology immediately post-treatment (risk ratio (RR) 0.80, 95% confidence interval (CI) 0.25 to 2.53; mean difference (MD) -2.30, 95% CI -6.51 to 1.91 respectively). In another trial with 88 women there was no difference in treatment response or depression remission rates in women receiving maternal massage compared with those receiving non-specific acupuncture (RR 1.33, 95% CI 0.82 to 2.18; RR 1.14, 95% CI 0.59 to 2.19 respectively).In a trial with 35 women acupuncture specifically treating symptoms of depression, compared with non-specific acupuncture, did not significantly decrease the number of women with clinical depression or depressive symptomatology immediately post-treatment (RR 0.47, 95% CI 0.11 to 2.13; MD -3.00, 95% CI -8.10 to 2.10). However, women who received depression-specific acupuncture were more likely to respond to treatment compared with those receiving non-specific acupuncture (RR 1.68, 95% CI 1.06 to 2.66).In a trial with 149 women, maternal massage by a woman's significant other, compared with standard care, significantly decreased the number of women with depressive symptomatology immediately post-treatment (MD -6.70, 95% CI -9.77 to -3.63). Further, women receiving bright light therapy had a significantly greater change in their mean depression scores over the five weeks of treatment than those receiving a dim light placebo (one trial, n = 27; MD -4.80, 95% CI -8.39 to -1.21). However, they were not more likely to have a treatment response or experience a higher remission rate (RR 1.79, 95% CI 0.90 to 3.56; RR 1.89, 95% CI 0.81 to 4.42).Lastly, two trials examined the treatment effect of omega-3 oils. Women receiving omega-3 had a significantly lower mean depression score following eight weeks of treatment than those receiving a placebo (one trial, n = 33; MD -4.70, 95% CI -7.82 to -1.58). Conversely, in a smaller trial (21 women) there was no significant difference in the change in mean depression scores for women receiving omega-3 and those receiving a placebo (MD 0.36, 95% CI -0.17 to 0.89), and women who received omega-3 were no more likely to respond to treatment (RR 2.26, 95% CI 0.78 to 6.49) or have higher remission rates (RR 2.12, 95% CI 0.51 to 8.84). Women in the placebo group were just as likely to report a side effect as those in the omega-3 group (RR 1.12, 95% CI 0.56 to 2.27).

AUTHORS' CONCLUSIONS

The evidence is inconclusive to allow us to make any recommendations for depression-specific acupuncture, maternal massage, bright light therapy, and omega-3 fatty acids for the treatment of antenatal depression. The included trials were too small with non-generalisable samples, to make any recommendations.
