Effects of home-based exercise on the health of patients with fibromyalgia syndrome: a systematic review of randomized clinical trials.

PURPOSE: Analyze the effects of interventions with home-based physical exercise on the health of patients with fibromyalgia and the characteristics of the protocols used. METHODS: This systematic review was registered at PROSPERO and followed the PRISMA recommendations. Searches were performed in six electronic databases. Eligibility criteria for the selection of studies were compiled using the acronym PICOS. Data were extracted and checked in a Microsoft Excel® spreadsheet and the risk of bias was assessed using the Rob 2 tool. RESULTS: The search resulted in seven studies included for analysis. Among them, the most common modality was aerobic exercise. The analyzed outcomes were: pain, quality of life, depression, anxiety, disease severity, physical function, pain catastrophizing, self-efficacy, psychological well-being, sleep quality and somatosensory and temporal discrimination. The effects of home-based exercise are limited, and improvements in pain and quality of life was found. For the other outcomes, the results were inconclusive. Most studies presented some concerns about the risk of bias. CONCLUSION: It is necessary to expand the evidence on home-based exercises for fibromyalgia, as this is the first systematic review on the subject. Subsequent research should focus on methodological rigor and protocol detail, allowing findings to be replicated.

Home-based physical exercise can improve pain and quality of life in patients with fibromyalgia.Among the modalities, combinations of aerobic exercise, resistance training and stretching are recommended.The weekly frequency should be two or three times, with an average duration of 40 minutes.Programs from four weeks onwards may already show improvement in symptoms, but the practice should be maintained in the long term.

Integrated use of biofeedback and neurofeedback techniques in treating pathological conditions and improving performance: a narrative review.

In recent years, the scientific community has begun tо explore the efficacy оf an integrated neurofeedback + biofeedback approach іn various conditions, both pathological and non-pathological. Although several studies have contributed valuable insights into its potential benefits, this review aims tо further investigate its effectiveness by synthesizing current findings and identifying areas for future research. Our goal іs tо provide a comprehensive overview that may highlight gaps іn the existing literature and propose directions for subsequent studies. The search for articles was conducted on the digital databases PubMed, Scopus, and Web of Science. Studies to have used the integrated neurofeedback + biofeedback approach published between 2014 and 2023 and reviews to have analyzed the efficacy of neurofeedback and biofeedback, separately, related to the same time interval and topics were selected. The search identified five studies compatible with the objectives of the review, related to several conditions: nicotine addiction, sports performance, Autism Spectrum Disorder (ASD), and Attention Deficit Hyperactivity Disorder (ADHD). The integrated neurofeedback + biofeedback approach has been shown to be effective in improving several aspects of these conditions, such as a reduction in the presence of psychiatric symptoms, anxiety, depression, and withdrawal symptoms and an increase in self-esteem in smokers; improvements in communication, imitation, social/cognitive awareness, and social behavior in ASD subjects; improvements in attention, alertness, and reaction time in sports champions; and improvements in attention and inhibitory control in ADHD subjects. Further research, characterized by greater methodological rigor, is therefore needed to determine the effectiveness of this method and the superiority, if any, of this type of training over the single administration of either. This review іs intended tо serve as a catalyst for future research, signaling promising directions for the advancement оf biofeedback and neurofeedback methodologies.

Improving Mental Skills in Precision Sports by Using Neurofeedback Training: A Narrative Review.

Primary objectives of neurofeedback training (NFT) are to improve concentration, stress and anxiety management, and performance optimisation. This narrative review examines the role of NFT as a tool to improve mental and cognitive skills of target shooting and archery athletes. Current research discusses how neurofeedback training can act on brain waves by influencing specific EEG frequency bands in order to improve cognitive flexibility. This contribution reports studies that have applied neurofeedback protocols in precision disciplines such as archery and shooting. The results of the studies considered showed that neurofeedback can lead to faster reaction times, more sustained attention, and better emotion management, contributing significantly to athletes' performance. Furthermore, it is emphasised that neurofeedback could be combined with other techniques such as motor imagination to maximise effectiveness in precision sports training. This review emphasises the importance of future studies that focus on the integration of neurofeedback with biofeedback in neuromodulation protocols. Current perspectives and limitations of research in this area are also indicated. Neuromodulation by means of neurofeedback represents a promising strategy to improve the overall mental and cognitive abilities of target shooting and archery athletes with an interesting potential for high-level performance. Future research should focus on integrated approaches and customised protocols to optimise the use of neurofeedback in a precision sports context.

Impact of social isolation caused by the COVID-19 pandemic on the mood profile of active and sedentary older adults: physical activity as a protective factor.

Background: The COVID-19 pandemic has changed our habits and lifestyle due to social isolation and mobility restrictions. This new scenario, together with the fear of contracting the coronavirus, influenced mental health, especially among older adults, who presented reductions in social contact and physical activity (PA). Thus, the objective of the study was to analyze the impact caused by social isolation during the COVID-19 pandemic on the mood states of active and sedentary older adults. Methods: This is an observational study conducted during the COVID-19 pandemic. Older adults aged over 60 years, who were registered in the database of the Secretariat for the Promotion of Citizenship from a city in southern Brazil, participated in the research. An online questionnaire was applied with questions about sociodemographic characteristics, level of PA, confinement, and mood states in two periods: May 2020 and June 2021. The Mann-Whitney U test was used to compare the mood states of active and inactive individuals during the pandemic. Results: One hundred and fifty participants answered the questionnaire, of which 80 (53.3%) reported practicing PA. More active older adults suffered fewer changes in mood when compared to inactive older adults, with lower levels of confusion (p = 0.035), depression (p = 0.002), and fatigue (p = 0.000). Older adults confined for more than 50 days were more likely to develop depression. In addition, the mood state correlated with the variable fear of contracting the coronavirus; the greater the fear, the greater the mental confusion, depression, fatigue, and tension, and the lower the vigor in the older adults. The practice of PA is also correlated with the mood state; the greater the number of hours dedicated to PA, the lower the confusion, depression, fatigue, and tension of the older adults. Conclusion: The practice of PA positively influenced the mental health of older adults during periods of isolation and social restrictions. PA has a protective factor for the development of mental health problems and improves mood states, with greater time performing PA leading to more benefits.

Impact of air pollution on the health of the older adults during physical activity and sedentary behavior: A systematic review.

BACKGROUND: Air pollution, in addition to presenting health risks, can impact the practice of physical activity (PA) and sedentary behavior (SB) in older adults. This study analyzed the impact of air pollution on the health of older adults during PA and SB, through a systematic review. METHODS: A keyword and reference search was performed in PubMed, SCOPUS, SPORTDiscus, and Web of Science. Predetermined selection criteria included study designs: interventions or experiments, retrospective or prospective cohort studies, cross-sectional studies and case-control studies; population: older adults aged 60 years or older; exposures: specific air pollutants (particulate matter (PM), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2), black carbon (CN), ultrafine particles (PU), nitrogen oxides (NOx) and biomass fuels) indoors and outdoors; and outcomes: physical activity and/or sedentary behavior. RESULTS: The beneficial effects of PA were attenuated or harmed in 11 studies, showing negative impacts on the health of the older adults, mainly by PM2.5 pollutants. On the other hand, in 10 studies the effects of PA were greater than the negative effects of air pollutants, with a greater frequency in relation to PM2.5. In general, even the articles presenting controversial results suggest that practicing PA in polluted environments is more favorable to the health of older adults than remaining in SB. DISCUSSION AND CONCLUSIONS: On the one hand, air pollution negatively impacted the health of the older adults during PA practices, while on the other hand, PA can mitigate the negative effects of pollutants on the health of older adults during the practices. Evidence shows that practicing PA in environments with low concentrations of pollutants can provide gains and reduce health risks. Remaining in SB in environments with high levels of air pollution worsens the health of older adults.

The Use of Voice Assistant for Psychological Assessment Elicits Empathy and Engagement While Maintaining Good Psychometric Properties.

This study aimed to use the Alexa vocal assistant as an administerer of psychometric tests, assessing the efficiency and validity of this measurement. A total of 300 participants were administered the Interpersonal Reactivity Index (IRI). After a week, the administration was repeated, but the participants were randomly divided into groups of 100 participants each. In the first, the test was administered by means of a paper version; in the second, the questionnaire was read to the participants in person, and the operator contemporaneously recorded the answers declared by the participants; in the third group, the questionnaire was directly administered by the Alexa voice device, after specific reprogramming. The third group was also administered, as a post-session survey, the Engagement and Perceptions of the Bot Scale (EPVS), a short version of the Communication Styles Inventory (CSI), the Marlowe-Crowne Social Desirability Scale (MCSDS), and an additional six items to measure degrees of concentration, ease, and perceived pressure at the beginning and at the end of the administration. The results confirmed that the IRI did keep measurement invariance within the three conditions. The administration through vocal assistant showed an empathic activation effect significantly superior to the conditions of pencil-paper and operator-in-presence. The results indicated an engagement and positive evaluation of the interactive experience, with reported perceptions of closeness, warmth, competence, and human-likeness associated with higher values of empathetic activation and lower values of personal discomfort.

Effect of rapid weight loss on mood states and burnout of Brazilian jiu-jitsu athletes during a competitive process.

The current study aimed to analyze the psychological alterations resulting from rapid weight loss in the mood states and burnout of male Brazilian jiu-jitsu athletes. For the purpose of this study, 31 Brazilian jiu-jitsu athletes participated, divided into two groups (RWLG: rapid weight loss group and CG: control group). Data collections were performed at three moments (1: baseline, before weight loss; 2: weigh-in, during the official competition; and 3: recovery, 7 to 10 days after the competition), with application of the Brunel Mood Scale (BRUMS) and Athlete Burnout Questionnaire (ABQ). Considering the outcomes, for body mass, the athletes from RWLG presented mean reductions of 3.5 kg (4.2% of the initial body mass). For mood states, both groups (RWLG and CG) presented a moment effect for tension and confusion, with higher levels during weigh-in compared to baseline and recovery (p < 0.05). For burnout, both groups showed low levels of burnout, with no effect of moment, group, or interaction in the analyses (p > 0.05). Based on these results, it is concluded that weight loss, in the magnitude performed in this study, did not generate an additional impact on mood or level of burnout in Brazilian jiu-jitsu athletes during a competitive process.

Effects of strength training in fibromyalgia on balance, neuromuscular performance, and symptomatic analysis: a 12-week study protocol.

Fibromyalgia affects skeletal muscles presenting with muscle stiffness, pain, and fatigue. The exercise practice is wellstabilized and suggested for the reduction of symptoms. However, there are some gaps in the literature related to balance and neuromuscular performance in a strength training protocol. The aim of this study is to structure a protocol to verify the effects of strength training applied over a short period, on balance, neuromuscular performance, and fibromyalgia symptoms. Additionally, we intend to analyze the effects of a short period of cessation of training. Participants will be recruited through flyers, internet advertisements, clinical referrals, health professionals, and email outreach. Volunteers will be randomly assigned to the control group or experimental group. Before the training period, symptoms (Fibromyalgia Impact Questionnaire, Visual Analog Scale), balance (force plate), and neuromuscular performance (medicine ball throw and vertical jump) will be assessed. Participants in the experimental group will perform strength training twice a week (50 min each), on alternate days, for 8 weeks (16 sessions). Then, 4 weeks of detraining will be completed. This training program will be carried out online, using real-time videos, and the participants will be divided into two groups with different schedules. The Borg scale will be used to monitor perceived effort in each session. There is a gap in the literature about exercise prescriptions for fibromyalgia. The supervised online intervention enables a wide range of participation. The strength exercises used (without the use of external materials and/or machines) and load (few repetitions per set) represent a novelty to training programming. Moreover, this training program respects the limitations and individuality of the volunteers, providing exercise adaptations. With positive results, the present protocol could be an easy-to-apply guideline with clear instructions on the details related to exercise prescription. Also, ensure the effectiveness of a low-cost and feasible treatment, especially for fibromyalgia patients. Clinical trial registration: https://clinicaltrials.gov/, identifier: NCT05646641.

Effects of resistance training on sleep of patients with fibromyalgia: A systematic review.

This study investigated the effects of resistance training (RT) on the sleep quality of patients with fibromyalgia (FM), through a systematic review. The search was carried out in the PubMed, Embase, Scopus, and Web of Science databases. Initially, 148 studies were found, of which six were included for qualitative analysis. Four studies showed significant improvement in sleep after RT. Compared to other exercise modalities, RT proved to be superior to flexibility training and equivalent to aerobic exercise. Interventions lasted from 4 to 21 weeks, the weekly frequency ranged from two to three times, and the intensity ranged from 40% to 80% 1RM, with exercises for the major muscle groups. RT is an intervention that can be used to treat FM, however, more studies are needed to verify its effectiveness in improving sleep.

Effects of Cognitive Appraisals on Perceived Self-Efficacy and Distress during the COVID-19 Lockdown: An Empirical Analysis Based on Structural Equation Modeling.

During the COVID-19 lockdown, individuals and households had to responsibly manage the difficulties and problems caused by the restrictions on their mobility, such as the interruptions to work schedules, insecure food supplies, and the procurement of services and health care. The perceptions of risk as well as the fear of disease were strongly linked to worry, defined as a sequence of thoughts that evoke negative emotions and elevated levels of anxiety and distress. This study evaluated how different cognitive appraisals of an individual's sources of worry could influence their perceived self-efficacy and directly or indirectly moderate their perceived general distress. A sample of 544 participants completed a survey that included questions based on the generalized self-efficacy scale, the sources of concern during the epidemic, the cognitive appraisal scale in emergency, and perceived discomfort. Subsequently, a structural-equation-modeling (SEM) analysis was performed to test the moderating role of cognitive appraisals and perceived self-efficacy on participants' overall distress during a lockdown. Overall, the model reported acceptable fit values and confirmed the hypotheses of the study. An individual's worries activated either a dysfunctional threat appraisal, which prompted a fear-and-closure response that then increased their overall state of distress; or two other functional appraisals (i.e., adaptive or supportive) that contributed to significantly improving the individual's self-efficacy. Higher self-efficacy was shown to be associated with lower levels of perceived distress. For the purposes of prevention and distress containment, it would be appropriate to promote psycho-educational interventions that promote the adoption of appraisal strategies that are functional and beneficial for perceived self-efficacy.

Effects of Air Pollution on the Health of Older Adults during Physical Activities: Mapping Review.

Atmospheric pollutants present environmental threats to health and have been investigated in different environments, such as highways, squares, parks, and gyms. These environments are frequented by older adults, who are considered fragile to the harmful impacts of pollution present in the air. The aim was to analyze the state of the art on the effects of air pollution on the health of older adults during physical activities (PAs) through a mapping review. The search was performed in PubMed, Web of Science, Scopus, and Cinahl databases until June 2022. Of the 10,109 studies initially identified, 58 met the inclusion criteria. The most investigated health outcome was cardiovascular disease, followed by respiratory outcomes. Particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), and ozone (O3) were the most investigated pollutants. Of the 75 health outcomes investigated, in 29, air pollution had harmful effects on the health of the older adults during the practice of PA, more frequently in cardiovascular diseases. In 25 outcomes, the beneficial effects of PA to the health of the older adults remained, despite exposure to high and low concentrations of pollutants, most often in terms of mental disorders. We conclude that poor air quality is a harmful factor for the health of older adults during the practice of PAs, more frequently in cardiovascular and respiratory diseases. On the other hand, for mental-health-related outcomes (depression and cognition), in most studies, the beneficial effects of PA in older adults were maintained, even after exposure to pollutants.

Effects of yoga on depressive symptoms, anxiety, sleep quality, and mood in patients with rheumatic diseases: Systematic review and meta-analysis.

OBJECTIVE: To investigate the effects of yoga on depressive symptoms, anxiety, sleep quality, and mood of patients with rheumatic diseases through a systematic literature review with meta-analysis. LITERATURE SURVEY: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement and the Cochrane recommendations and risk of bias tool. The study was registered in the International Prospective Register of Systematic Reviews (PROSPERO). Studies were selected using the PICOS (participants, intervention, comparison, outcome, and study) strategy. Searches were carried out until March 2022 and performed in Web of Science, PubMed, SportDiscus, Scopus, Cochrane, and EBSCO databases. METHODOLOGY: Data were extracted to identify the differences between yoga and control and exercise groups and effect sizes. SYNTHESIS: In total, 27 studies were included for qualitative analysis and 18 for meta-analysis. The studies found investigated yoga in patients with osteoarthritis, fibromyalgia, rheumatoid arthritis, and chronic fatigue syndrome. Regarding the risk of bias, the majority of studies showed a high risk or uncertain risk of bias in several criteria. Regarding the meta-analysis, yoga was favored to decrease depressive symptoms (standard mean difference [SMD]:-0.88; 95% confidence interval [CI]:-1.42; -0.34), anxiety (SMD: -0.51; 95% CI = -0.81 to -0.20), and improve sleep quality SMD = -0.96; 95% CI = -1.36 to -0.56). No differences were found between yoga and other exercise modalities in depression (p < .01). CONCLUSIONS: Yoga is effective in improving depression, anxiety, and sleep quality of patients with rheumatic diseases. However, research in this field still needs further studies, because of methodological issues in the studies and a reduced number of studies conducted on each rheumatic disease and on the effects of yoga on each variable.

Effects of resistance training on the physical symptoms and functional capacity of patients with fibromyalgia: a systematic review and meta-analysis of randomized clinical trials.

BACKGROUND: Resistance training (RT) has become an important topic for the treatment of fibromyalgia (FM); however, there are still controversies regarding its ability to significantly improve physical symptoms and a lack of adequate recommendations for evidence-based practice. AIM: The aim of this study is to analyze the effects of RT on the physical symptoms of patients with FM through a systematic review with meta-analysis. METHODS: We conducted a systematic review of randomized controlled trials in June 2022, according to PRISMA recommendations. The searches were carried out on the databases PubMed, Embase, Science Direct, Web of Science, PEDro, CINAHL, SciELO, and Google Scholar for gray literature, and the protocol was recorded in PROSPERO. Studies that evaluated patients with FM undergoing an RT program lasting more than 2 weeks and that analyzed physical health were selected. To carry out the meta-analysis, the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions were followed. RESULTS: In total, 13 studies were included for qualitative analysis and nine for meta-analysis. Regarding meta-analysis, a favorable improvement was found for pain ([MD = - 10.22 (95% CI: - 18.86 to - 1.58; I2: 64%; P for heterogeneity: 0.003)]; very low quality of evidence {QoE}), fatigue ([SMD = - 0.39 (95% CI: - 0.61 to - 0.17; I2: 0%; P = 0.91)]; moderate QoE), and muscle strength ([SMD = 0.94 (95% CI: 0.02 to 1.85; I2: 93%; for heterogeneity: < 0.0001)]; very low QoE) and improvement in functional capacity ([MD = 18.75 (95% CI: 4.27 to 33.22; I2: 39%; P = 0.19)]; low QoE), in the general comparison. CONCLUSION: RT was effective in reducing pain and fatigue and increasing strength and functional capacity; however, due to the quality of the evidence, more studies are needed.

Impact of the COVID-19 pandemic on the psychological aspects and mental health of elite soccer athletes: a systematic review.

Introduction: Investigation of the psychological impact on soccer athletes during the pandemic is essential given their unique challenges, including training disruptions and competition postponements. Understanding these effects will allow the development of specific strategies to preserve the mental health and performance of elite athletes, contributing to effective interventions with both short and long-term benefits. Objective: To analyze the impact of the COVID-19 pandemic on the psychological aspects and mental health of elite soccer athletes. Method: The review adhered to PRISMA criteria, and the study protocol was registered in the International Prospective Register of Systematic Reviews (CRD42022341545). Searches were conducted until July 2023 in databases including Cochrane, PsycINFO, PubMed, Scopus, SPORTDiscus, and Web of Science. Only original, peer-reviewed studies in English, Portuguese, or Spanish assessing the impact of the COVID-19 pandemic on the psychological aspects and mental health of elite soccer athletes were included. Results: The search identified 1,055 records and 43 studies were included in this review between 2020 and 2023. In total, the sample included 16,321 soccer athletes of different age groups. Anxiety, depression, mood states, and mental well-being were the most investigated variables. Increased levels of anxiety, depression, and worsening mental well-being were observed in elite soccer athletes. Maintaining fitness during the pandemic showed positive results. Other variables, such as coping, resilience, and sleep quality monitoring, were less widely investigated. Evaluating methodological quality was considered regular for observational and experimental studies. Conclusion: The study reveals a negative impact of the COVID-19 pandemic on elite soccer athletes, considering psychological aspects and their mental health, notably heightened anxiety and depression. Observational methods predominated, showing mood swings linked to individual characteristics and fitness maintenance efforts. Studies with better-designed methodological approaches and controlled experimental interventions are recommended in the future to mitigate the negative effects of the pandemic on soccer players.

Strength training in patients with fibromyalgia: a feasibility study / Entrenamiento de fuerza en pacientes con fibromialgia: un estudio de factibilidad / Treinamento de força em pacientes com fibromialgia: um estudo de viabilidade

ABSTRACT Introduction: Fibromyalgia syndrome (FM) is characterized by the presence of diffuse pain lasting for more than three months and is often associated with sleep disorders. Studies have investigated the effect of strength training (ST) on pain and sleep quality in FM patients, but there continue to be diverse perspectives on the effects of this intervention in this population. Objective: The aim of the study was to examine the effects of strength training (ST) on pain and sleep quality in FM patients. Methods: Forty-eight women with FM participated in the study between August and October, 2012. Six (55±6.5 years) performed ST, conducted at Santa Catarina State University, and eight (47±9 years) comprised the control group. The Socio-Demographic and Clinical Questionnaire, the visual analog scale (VAS) for pain, and the Pittsburgh Sleep Quality Index were used. Data were collected before the first session and after the eight-week intervention and were analyzed using descriptive statistics and inferential tests. Results: The eight- week ST intervention decreased pain (p< 0.05) and significantly diminished the daytime sleep dysfunctions (p< 0.05), demonstrating that the proposed program contributes to improving patient quality of life. Conclusion: ST is a feasible treatment for patients with fibromyalgia. Level of evidence II; Therapeutic study.

Conclusão: O ST é um tratamento viável para pacientes com fibromialgia. Nível de evidência II; Estudo terapêutico.

Perceived Pain in Athletes: A Comparison between Endurance Runners and Powerlifters through a Cold Experimental Stimulation and Two Sessions of Various Physical Activation.

Few studies in the literature have illustrated cold hypoalgesia induced by strength training. Objectives of this contribution were to compare the ratings of perceived pain in endurance running (n = 22) and powerlifting (n = 22) male athletes and controls (n = 22) at baseline and after two bouts of 40 min aerobic/strength training respectively, using the Cold Pressor Test (CPT) and simultaneously monitoring changes in blood pressure (BP), heart rate (HR), and body temperature. A two-way repeated measures ANOVA was conducted to examine the effects of training sessions in endurance runners vs. powerlifting athletes vs. controls on the intensity of perceived pain at CPT. A statistically significant two-way interaction between the group and training resulted in p < 0.001, ηp2 = 0.513. A simple main effects analysis showed that as the participants went through the strength training session, pain perception at CPT was significantly lower in powerlifters compared to runners and controls. Considering the physiological parameters, powerlifters reported significantly higher values of BP and HR. This difference was present at baseline but after training as well, and before and after CPT, despite a slight hypotensive effect. The differences reported after CPT at baseline, but very significantly after the strength activation session in the powerlifters, provide interesting insights into the hypoalgesic effect of high-intensity strength training.

A Rehabilitation Program for Individuals With Chronic Low Back Pain: Protocol for a Randomized Clinical Trial.

BACKGROUND: Low back pain (LBP) is the leading cause of disability worldwide. Physical exercise, as a treatment, is beneficial for the improvement of quality of life in patients with LBP, and it is widely accepted. OBJECTIVE: We aimed to develop a protocol for a feasibility study that is designed to compare the effectiveness of different interventions in reducing pain, functional, and psychosocial factors among patients with chronic LBP after 8 weeks of randomization. METHODS: This is a study protocol for a randomized controlled trial that will consist of individuals with chronic LBP who are aged between 18 and 65 years. Participants will be allocated, through block randomization, to one of the following groups: the motor control exercises (MCEs), pain education, MCEs+pain education, and usual care groups. The primary outcome will be pain intensity, and the secondary outcomes will be the pressure pain threshold, which will be measured with a digital algometer; LBP-related disability; fears and beliefs; the fear of movement; quality of life; mood states; and levels of depression and anxiety. The trial was approved by the ethics committee for research involving human beings of the Federal University of Pelotas (reference number: 5.717.390) in September 2022, and it will be conducted until August 2023. RESULTS: The researchers are being trained to apply the questionnaires and carry out the interventions. Patient recruitment will begin at the end of 2022 and results are expected to be achieved by August 2023. CONCLUSIONS: Our trial will provide preliminary data regarding the feasibility and safety of MCEs and pain education for patients with LBP. It will also provide preliminary outcome data that can be used to identify the most efficient intervention and the level of health care that should be implemented in public health services.

A Psychoeducational Intervention in Prenatal Classes: Positive Effects on Anxiety, Self-Efficacy, and Temporal Focus in Birth Attendants.

BACKGROUND: Previous studies have reported associations between high maternal anxiety, temporal perceptions during pregnancy, and a poor sense of self-efficacy. One type of anxiety expecting mothers experience is associated with childbirth, which previous studies have shown can be reduced by antenatal training. Recent contributions have pointed out that current prenatal courses, while providing important and useful knowledge, do not devote sufficient content to the mental health of the parturient and to the psychological issues that can arise before and after the birth. METHODS: In total, 80 pregnant women were provided with a special prepartum course in which ample space was devoted to topics such as maternal mental health, parenting skills and couple relationship, relaxation techniques, and assertiveness. Perception of threat, state anxiety, temporal focus, needs and expectations, and self-efficacy were assessed by comparing this psychoeducational intervention group with a traditional antenatal course group (n = 80), and a control group (n = 80). Two-way mixed ANOVAS (3 × 2) were performed for each dependent variable considered, including the time variable (pre-course-post-course) as a factor within the participants and the group variable as a factor between the subjects. RESULTS: The psychoeducational intervention actually induced significant and positive changes primarily on four dimensions: state anxiety, perceived self-efficacy, the need for information, and reassurance of the pregnant women who participated in this trial. CONCLUSIONS: The study suggests improving the quality of prenatal classes by paying particular attention to the content and communication used within the group, in order to gratify at the highest level, the need for information, reassurance, and sharing that characterize the parturient's request for support. The evidence collected recommends further replicating the intervention protocol described in order to improve the psychophysical well-being of women in a delicate moment such as pregnancy and preparation for childbirth, but especially in terms of the prevention and containment of the risks of psychological distress that currently affect a significant number of women after childbirth.
