Schizophrenia and Progressive Muscle Relaxation - A systematic review of effectiveness

The effect of progressive relaxation exercise on fatigue level of intensive care nurses: A randomised controlled trial

OBJECTIVE

The aim of this study is to examine the effect of progressive muscle relaxation exercise on the fatigue level of intensive care nurses.

METHODS

In this clinical trial, the participants were randomly assigned to the intervention (n = 38) and control (n = 37) groups after obtaining necessary approvals. The nurses in the intervention group applied progressive muscle relaxation every day for 4 weeks, with each session lasting for 15 min. None of the participants in the control group were subjected to any intervention. Data were collected using a questionnaire and the fatigue severity scale (FSS) (the lower the total score, the less the fatigue). The questionnaires were applied at the baseline, and the FSS was applied at the baseline and the end of the first, second, third, and fourth weeks.

RESULTS

While the FSS mean scores of the intervention and control groups at baseline were 4.84 ± 1.01 and 5.23 ± 0.96, respectively (p = 0.086), the FSS mean score of the intervention group (3.13 ± 1.58) was significantly lower than the score of the control group (4.12 ± 1.70) at the fourth week (p = 0.011). Also in the 1st, 2nd, and 3rd weeks of the study, the FSS scores of the nurses in intervention group decreased statistically significantly compared to that of the nurses in the control group.

CONCLUSIONS

This study indicated that a 4-week progressive muscle relaxation intervention alleviated fatigue in intensive care nurses.

Effects of a Muscle Relaxation Technique on Catatonia Symptoms Associated With Schizophrenia: A Case Report

Catatonia is characterized by the loss of voluntary control over the workings of the mind and body. It disrupts daily life by manifesting as idle posture, heightened muscle tone, and repetitive purposeless movements. However, specific physiotherapy methods addressing these symptoms are yet to be established. This case report describes a 63-year-old man hospitalized for schizophrenia who was then diagnosed with stuporous catatonia based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria, characterized by catalepsy, mutism, and difficulty performing daily activities. This case report aimed to evaluate the effectiveness of a specific muscle relaxation technique, squeeze-hold (SH), in treating catatonia associated with schizophrenia and its impact on daily activities. The patient exhibited catalepsy, mutism, and difficulty in performing daily activities. The SH technique employed temporarily obstructs muscle blood flow to induce ischemia, resulting in the relaxation of vascular smooth muscle due to CO2 retention. Furthermore, shear stress upon reperfusion stimulates nitric oxide production in the vascular endothelium, enhancing blood flow. Following weekly SH on the bilateral thighs, the muscle tone in the lower extremities was alleviated within two weeks, and the patient no longer required a wheelchair by the eighth week. In addition, responsiveness to verbal commands improved. As muscle tone in the lower limbs improved, the patient regained ambulation, and his improved responsiveness facilitated independent eating during activities of daily living (ADLs), potentially enhancing motivation and spontaneity. These findings suggest that muscle tone relaxation due to enhanced blood flow and increased CO2 concentration from blood flow restriction may have promoted β-endorphin secretion, thereby improving symptoms via brain-derived neurotrophic factor expression through PGC-1α activation. In conclusion, the SH muscle relaxation technique effectively alleviated catatonic symptoms, and improved muscle tone and daily functioning in patients with schizophrenia-associated catatonia. These findings suggest that this physiotherapy approach may be a valuable addition to catatonia treatment, potentially contributing to physical and psychiatric rehabilitation. This case report illustrates the efficacy of a muscle-tone-focused treatment approach in physical therapy for catatonia and posits its contribution to the reacquisition of psychiatric function and ADLs.

The efficacy of progressive muscle relaxation training on cancer-related fatigue and quality of life in patients with cancer: A systematic review and meta-analysis of randomized controlled studies

BACKGROUND

Cancer-related fatigue is one of the most common symptoms in cancer patients, usually accompanied by anxiety, depression and insomnia, which seriously affect patients' quality of life. Progressive muscle relaxation training is widely used for cancer-related fatigue, but the overall effect is unclear.

OBJECTIVES

The aim of this study was to summarize the evidence on the effects of progressive muscle relaxation training on cancer-related fatigue and quality of life in cancer patients.

DESIGN

Systematic review and meta-analysis.

METHODS

Nine electronic databases (PubMed, Excerpta Medica Database (Embase), The Cochrane Library (Cochrane Central Register of Controlled Trials, CENTRAL), Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Chinese Biomedical Literature Database (CBM), Chinese National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP) and Wanfang Database) were explored for randomized controlled trials (RCTs) published before February 2023. This study was reported based on the PRISMA 2020 statement. The Cochrane Collaboration's risk of bias assessment tool was used for methodological assessment, and the GRADE pro online assessment tool was used for evidence evaluation. The data were analyzed with the Review Manager 5.4 software.

RESULTS

Twelve studies involving 1047 patients were included. Meta-analysis showed that progressive muscle relaxation training plus routine nursing produced more positive effects than routine nursing in improving cancer-related fatigue [SMD = -1.06, 95 % CI -1.49, -0.62, P < 0.00001], anxiety [SMD = -1.09, 95 % CI -1.40, -0.77, P < 0.00001], depression [SMD = -1.43, 95 % CI -1.76, -1.10, P < 0.00001], and quality of sleep [MD = -1.41, 95 % CI -1.74, -1.08, P < 0.00001]. However, there was no significant difference in improving quality of life [SMD = 0.27, 95 % CI -0.62, 1.15, P = 0.55]. Progressive resistance exercise plus routine nursing improved cancer-related fatigue more than progressive muscle relaxation training plus routine nursing [SMD = 1.11, 95 % CI 0.43, 1.78, P = 0.001]. There was low certainty of evidence that progressive muscle relaxation training improved cancer-related fatigue and quality of sleep, and the evidence that improved quality of life, anxiety and depression was very low.

CONCLUSION

Current evidence suggested that progressive muscle relaxation training has the potential to improve cancer-related fatigue, anxiety, depression and quality of sleep in patients with cancer and is a low-load, simple exercise worthy of recommendation for cancer patients in fatigue state. Future research should focus on improving the methodological quality of randomized controlled trials to enhance the persuasive evidence of progressive muscle relaxation training efficacy.

Efficacy of Progressive Muscle Relaxation in Adults for Stress, Anxiety, and Depression: A Systematic Review

Background

The rise in the prevalence of mental health problems among adults worldwide has raised concerns, highlighting the critical need for evidence-based mental health interventions that are accessible, comprehensive, and effective. Previous research suggests that Progressive Muscle Relaxation (PMR) is a promising intervention widely used to reduce mental health problems. Nevertheless, the current literature on the efficacy of PMR among adults globally is fragmented, indicating a potential gap in this research area. Hence, this paper aims to systematically compile the research evidence on the efficacy of PMR in adults for stress, anxiety, and depression.

Methods

The Scopus, Web of Sciences, PubMed, PsycINFO, and Cochrane Central Register of Controlled Trials were searched from the earliest available evidence to 28th March 2023. The PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-analyses) guidelines were followed, and the protocol was registered on the Open Science Framework. Joanna Briggs Institute (JBI) Critical Appraisal Tools were used to assess the quality of the included studies.

Results

A total of forty-six (46) publications from sixteen (16) countries covering more than 3402 adults were included in the review. The results show that PMR are effective in reducing stress, anxiety, and depression in adults. When PMR is combined with other interventions, the combined techniques have also consistently exhibited enhanced efficacy. Moreover, findings also indicate that the efficacy of PMR is heightened when implemented in conjunction with other interventions, surpassing its standalone efficacy.

[Toward a better understanding of fatigue in schizophrenia]

Despite being one of the most common complaints of people with schizophrenia, fatigue remains largely unexplored in this population. The lack of knowledge regarding this complex symptom makes it often underdiagnosed and undertreated in schizophrenia. The aim of this brief perspective review is to outline the potential origins (distinguishing primary and secondary fatigue) and consequences of fatigue and to explore some potential treatments in this population. The current literature in schizophrenia has mainly investigated fatigue as a trait, using a self-administered questionnaire. Beyond this observational approach, which does not allow to capture the symptom in real life situations where high levels of fatigue can emerge rapidly, we propose to consider the state level of fatigue, for instance occurring after a prolonged period of cognitive activity (i.e. mental fatigue). We elaborate on the potential relationships between mental fatigue and negative symptoms of schizophrenia and propose some research avenues to test the effects of acute fatigue on effort intentions and behaviours. The consideration of the multidimensional aspects of fatigue will allow to move beyond the sole pharmacological approach to treat fatigue in schizophrenia. Targeting the cognitive as well as the performance components of fatigue through interventions such as concomitant aerobic exercise - mental training offers attractive prospects to reduce fatigue in this population and minimize its functional negative impact.

Development and validation of audio-based guided imagery and progressive muscle relaxation tools for functional bloating

Mind-body techniques, including Guided Imagery (GI) or Progressive Muscle Relaxation (PMR), may effectively manage bloating. The current study aimed to develop and validate (psychometric and psychological responses) audio-based GI and PMR techniques for bloating. Audio scripts were first developed from literature reviews and in-depth interviews of participants with bloating diagnosed based on the Rome IV criteria. Scripts were validated using psychometric (content & face validity index) and physiological approaches (brain event-related potentials & heart rate variability). 45/63 participants completed the in-depth interview, and ‘balloon’ emerged as the synonymous imagery description for bloating, of which inflation correlated with a painful sensation. The final tools consisted of narrated audio scripts in the background of a validated choice of music. Overall, the content and face validity index for PMR and GI ranged from 0.92 to 1.00. For ERP and HRV, 17/20 participants were analyzed. For ERP, there was a significant difference between GI and PMR for alpha waves (p = 0.029), delta waves (p = 0.029), and between PMR and control for delta waves (p = 0.014). For HRV, GI and PMR exhibited similar autonomic responses over controls (overall p<0.05). The newly developed GI and PMR audio-based tools have been validated using psychometric and physiological approaches.

OBJECTIVE

To analyze the effects of the technique of virtual reality guided imagery in the vital signs of hematopoietic stem-cell transplantation patients.

METHOD

Quasi-experimental study with 35 participants who received an intervention using virtual reality guided imagery with progressive muscle relaxation, applied three times a week for four weeks in a referral hospital for transplants in the south of Brazil. Data collected included: temperature, arterial pressure, respiratory rate, heart rate, pain, and oxygen saturation, before and after each intervention. The comparisons were analyzed using Wilcoxon's test.

RESULTS

There was a clinical significance between the mean measurements before and after for respiratory rate (p=0.00) in all stages, and for the variables Heart rate, Temperature, and Oxygen saturation from the 1st to the 12th measurements (p=0.05).

CONCLUSION

The intervention was low cost, easy to apply, and showed positive effects, presenting itself as an option for patient-focused care.

The Mental Health of Patients With Psychotic Disorder From a Positive, Multidimensional and Recovery Perspective

Positive mental health (PMH) and mental illness are distinct, yet interrelated, constructs. However, this relationship has yet to be adequately established. We aimed to evaluate the level of PMH and its relationship with sociodemographic and clinical determinants as well as to explore the relationship between PMH and the positive constructs of recovery, subjective wellbeing (SWB), insight and functioning in patients with psychotic disorder. A multicenter, descriptive, cross-sectional and correlational study with a sample of 347 patients with psychotic disorder was conducted. The following assessment instruments were used: Positive Mental Health Questionnaire, Maryland Assessment of Recovery in Serious Mental Illness scale, Insight Scale, Personal Wellbeing Index-Adult version (PWI-A), Overall Life Satisfaction (OLS) and Global Assessment of Functioning scale. The mean global level of PMH was 116.16 (range of 39–156, SD = 19.39). Significant differences were found in PMH in relation to sociodemographic (sex, civil status and employment situation) and clinical variables (family history of mental disorders, number of prescribed antipsychotics, treatment with anxiolytics, treatment with antidepressants and suicide attempts). PMH was significantly and positively correlated with recovery (r = 0.760), SWB (PWI-A: r = 0.728 and OLS: r = 0.602) and functioning (r = 0.243), and negatively with insight (r = −0.335). These results can lead to a major change in mental health care. If actions are taken to increase PMH, then recovery, SWB and functioning will also increase. At the same time, interventions should be carried out to boost insight, since increasing PMH could decrease insight, all resulting in better quality of life for patients with psychotic disorder.

Effectiveness of progressive muscle relaxation and laughter therapy on mental health and treatment outcomes in women undergoing in vitro fertilization: A randomized controlled trial

A majority of infertile women experience emotional problems, such as anxiety and depression. Nurses need nonpharmacological methods rather than drugs to address women's emotional distress during the in vitro fertilization (IVF) process. The purpose of this study was to examine the effect of progressive muscle relaxation exercises and laughter therapy on the mental health and treatment outcomes of women receiving IVF treatment. This parallel-group, randomized controlled trial was conducted in a private IVF center. Participants were randomly assigned to the intervention group (IG; n = 71) and control group (CG; n = 70). The IG received progressive muscle relaxation and laughter therapy for 40 min in each session for 3-4 sessions, whereas the CG received routine care. Data were obtained from the patient information form, State-Trait Anxiety Inventory, Beck Depression Inventory, and medical records. The questionnaire was completed at recruitment (T1) and oocyte pick-up day (T2). In the evaluation performed on the day of the oocyte pick-up, depression and trait anxiety scores of the IG were found to be lower than those in the CG, and the effect size was small. Group × time interaction was significant for depression (large effect size) and trait anxiety (small effect size). The estradiol levels, the number of oocytes, transfer status, and pregnancy rates (according to a blood test) were similar between groups. Women receiving IVF treatment who received progressive muscle relaxation and laughter therapy demonstrated psychological changes; however, the treatment did not affect medical outcomes.

A mixed-method randomized feasibility trial evaluating progressive muscle relaxation or autogenic training on depressive symptoms and quality of life in people living with human immunodeficiency virus (HIV) who have depressive symptoms

BACKGROUND

Progressive muscle relaxation (PMR) and autogenic training (AT) are effective relaxation techniques to reduce depressive symptoms. However, no studies on their effectiveness have been conducted among people living with HIV and depressive symptoms. The primary aim of this pilot study was to assess the feasibility and acceptability of PMR and AT interventions among people living with HIV who have depressive symptoms. A secondary aim was to assess the potential effectiveness of these interventions on depressive symptoms and quality of life.

METHODS

This study was a three-arm pilot randomized control trial with mixed methods. Participants were randomized to PMR, AT, or a control group (CG), with four assessments (baseline, and at one, three, and six months). The PMR and AT interventions consisted of six 1 h sessions of individual training over 12 weeks, plus home practice. Recruitment, attrition, and completion rates were calculated. Depressive symptoms and quality of life were assessed at all times. Participants' perceptions of the interventions were collected in semi-structured interviews.

RESULTS

Following the screening, 54/63 people met the inclusion criteria, and 42/54 were randomly allocated to the PMR group (n=14), AT group (n=14), and CG (n=14). Six participants (43%; 95% CI 18-71%) in the PMR group and 10 (71%; 95% CI 42-92%) in the AT group completed the intervention. Participants reported better emotion management and improvements in depressive symptoms and quality of life.

CONCLUSIONS

The pilot study suggests that a randomized trial to test the effectiveness of these interventions is feasible.
