Progressive Muscle Relaxation Training Research Articles

The Importance of Including Psychophysiological Methods in Psychotherapy.

This paper describes characteristics of sophisticated use of psychophysiological therapy procedures and describes a scoping review of evidence that adding psychophysiological procedures to psychotherapy improves outcome. It also reviews literature describing comparisons between psychophysiological procedures and various CBT and other verbal psychotherapy procedures when used as monotherapies. Some details of progressive muscle relaxation, autogenic training, and biofeedback are described that often are omitted in standard clinical training, including the method of diminishing tensions and differential relaxation training in progressive muscle relaxation, use of autogenic discharges and hypnotic instructions in autogenic training, and resonance frequency training in heart rate variability biofeedback and slow breathing. Although these details are often also missing in outcome studies, tentative conclusions can still be drawn from the empirical literature. As a monotherapy, psychophysiological methods are generally as powerful as verbal psychotherapies, although combining them with psychotherapy yields a larger effect than either approach alone. Psychophysiological methods have their strongest effects on anxiety and depression, with weaker effects for panic and PTSD, particularly when compared with exposure therapy, although the latter comparisons were restricted to relaxation training as a psychophysiological approach. Effects of psychophysiological interventions are weaker among elementary school children than among adults and adolescents. The results suggest that psychophysiological methods should be used along with other psychotherapeutic interventions for greatest effect.

Bivariate analysis used the Wilcoxon test and the Man Whitney test. The results of the study showed that there was a significant effect between reducing blood pressure in hypertension sufferers before and after being given progressive muscle relaxation (PMR) in the working area of the Putri Ayu Community Health Center, Jambi City.

Progressive Muscle Relaxation Training During Pregnancy: Effects on Mental State, Delivery and Labour Pain - a Prospective Study.

Progressive muscle relaxation is a widely used technique for relaxation, but studies are rare about efficacy on pregnancy and perinatal outcomes. Aim of our study was to determine whether progressive muscle relaxation affects anxiety and depression levels of pregnant women, pregnancy outcomes, labour pain and analgesic requirements. 156 pregnant women were enrolled in a prospective non-randomized controlled cohort study. The control group received standard antenatal care and classes only, while the intervention group additionally received progressive muscle relaxation training once a week for six weeks. Anxiety, depression and current strain were measured in a pretest-posttest experimental design using self-report scales at baseline (1 st survey), 5 weeks later (2 nd survey) and during puerperium (3 rd survey). Numeric Rating scales were used for measuring labour pain and satisfaction with analgesic treatment in the 3 rd survey. Fifty complete questionnaires from each group were analysed. There were no differences in mental status between the groups at baseline. Progressive muscle relaxation training significantly reduced depression levels. Trait anxiety, reflecting a person's basic anxiety decreased significantly in both groups during puerperium. No differences in pregnancy outcomes, labour pain and analgesic requirements could be shown within both groups in general. Nonetheless, women attending more than five progressive muscle relaxation courses reported significantly less labour pain within the group and compared to controls. Pregnant women could benefit from progressive muscle relaxation training if used continuously. Relaxation methods should be a substantial part of prenatal care and available for everyone.

The effectiveness of expressive art therapy on infertile women undergoing surgery: study protocol for a randomized controlled trial

BackgroundInfertility produces infertility-related stress in both members of infertile couples, especially for infertile women. Some studies verified the negative relationship between infertility-related stress and outcomes of infertility treatments. Effective mental health care during fertility treatment is urgently needed, but there has been a lack of efficient support services. To reduce the infertility-related stress of infertile women, expressive art therapeutic schemes will be organized and implemented by certified international expressive art therapists.MethodsThis study is a randomized controlled trial. Participants in the intervention group will receive expressive art therapies after the baseline investigation. Expressive art therapies will be led by the certified international expressive art therapist. The interventions include progressive muscle relaxation training, music meditation and drawing therapy. Participants in the control group will receive routine care. The Hospital Anxiety and Depression Scale (HADS) and Fertility Problem Inventory (FPI) will be used to investigate the anxiety, depression, and infertility-related stress of all participants at admission and at discharge.DiscussionThis study will verify the effectiveness and efficiency of expressive art therapies for infertile women. The results will provide new knowledge on mental health care strategies for infertile women.Trial registrationChiCTR, ChiCTR2300070618. Registered 14 April 2023.

Effects of Progressive Muscle Relaxation Training on Anxiety, Depression, and Quality of Life in Patients with Cerebral Small Vessel Disease

Objective: To explore the effects of progressive muscle relaxation training on anxiety, depression, and quality of life in patients with cerebral small vessel disease (CSVD). Methods: Sixty-one patients with CSVD in the Department of Neurology of a tertiary hospital were divided into an observation group (28 patients) and a control group (33 patients) by lottery method. The control group received conventional nursing care, while the observation group received progressive muscle relaxation training interventions in addition to the conventional care. The Hamilton Anxiety Scale (HAMA), the Hamilton Depression Scale (HAMD), and the Stroke-Specific Quality of Life Scale (SS-QOL) were used to compare the effects before the intervention, 7 days after the intervention, and 30 days after the intervention. Results: Over time, at different time points after the intervention, the anxiety and depression scores of patients with CSVD in the observation group were significantly lower than those in the control group (P < 0.05). The quality of life scores were significantly higher in the observation group compared to the control group (P < 0.05), and these differences were statistically significant. Conclusion: Progressive muscle relaxation training can improve anxiety and depression in patients with cerebral small vessel disease and can effectively enhance their quality of life.

Efficacy and Neural Mechanisms of Mindfulness Meditation Among Adults With Internet Gaming Disorder

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), recently identified internet gaming disorder (IGD) as a condition warranting more research, and few empirically validated treatments exist. Mindfulness meditation (MM) has multiple health benefits; however, its efficacy in treating IGD and potential neural mechanisms underlying MM treatment of the disorder remain largely unknown. To explore the efficacy of MM used to treat adults with IGD and to identify neural mechanisms underlying MM. This randomized clinical trial was performed from October 1 to November 30, 2023, at Hangzhou Normal University in Hangzhou, China. Adults (aged ≥18 years) who met at least 6 of the 9 DSM-5-TR proposed criteria for IGD were recruited to receive either MM or progressive muscle relaxation (PMR). Data analysis was performed on December 1, 2023. Participants underwent MM training (an 8-session meditation program that focuses on attention and acceptance) and PMR training (an 8-time program for body relaxation) delivered in groups that met 2 times each week for 4 weeks. This per-protocol analysis included only participants who finished the pretest assessment, 8 training sessions, and posttest assessment. The main outcomes were addiction severity (measured with the DSM-5-TR proposed criteria for IGD and with Internet Addiction Test scores), gaming craving (measured with Questionnaire for Gaming Urges scores), and blood oxygen level-dependent signals assessed with cue-craving tasks on fMRI. Behavioral and brain measurements were compared using analysis of variance. Functional connectivity (FC) among identified brain regions was measured to test connectivity changes associated with MM. This study included 64 adults with IGD. A total of 32 participants received MM (mean [SD] age, 20.3 [1.9] years; 17 women [53%]) and 32 received PMR (mean [SD] age, 20.2 [1.5] years; 16 women [50%]). The severity of IGD decreased in the MM group (pretest vs posttest: mean [SD], 7.0 [1.1] vs 3.6 [0.8]; P < .001) and in the PMR group (mean [SD], 7.1 [0.9] vs 6.0 [0.9]; P = .04). The MM group had a greater decrease in IGD severity than the PMR group (mean [SD] score change for the MM group vs the PMR group, -3.6 [0.3] vs -1.1 [0.2]; P < .001). Mindfulness meditation was associated with decreased brain activation in the bilateral lentiform nuclei (r = 0.40; 95% CI, 0.19 to 0.60; P = .02), insula (r = 0.35; 95% CI, 0.09 to 0.60; P = .047), and medial frontal gyrus (MFG; r = 0.43; 95% CI, 0.16 to 0.70; P = .01). Increased MFG-lentiform FC and decreased craving (pretest vs posttest: mean [SD], 58.8 [15.7] vs 33.6 [12.0]; t = -8.66; ƞ2 = 0.30; P < .001) was observed after MM, and changes in MFG-lentiform FC mediated the relationship between increased mindfulness and decreased craving (mediate effect, -0.17; 95% CI, -0.32 to -0.08; P = .03). In this study, MM was more effective in decreasing addiction severity and gaming cravings compared with PMR. These findings indicate that MM may be an effective treatment for IGD and may exert its effects by altering frontopallidal pathways. Chinese Clinical Trial Registry Identifier: ChiCTR2300075869.

The influence of mindfulness meditation combined with progressive muscle relaxation training on the clinical efficacy and quality of life of patients with sarcopenia receiving haemodialysis: a randomised controlled trial

ObjectiveTo study the effect of mindfulness meditation combined with progressive muscle relaxation training on the clinical efficacy and quality of life in patients with sarcopenia receiving maintenance haemodialysis (MHD).MethodsEligible patients with sarcopenia in our hospital were randomly assigned to a control group (n = 24) and an intervention group (n = 25). The control group received conventional dialysis treatment, while the intervention group underwent mindfulness meditation combined with progressive muscle relaxation training during the interdialysis period in addition to conventional dialysis treatment. The effect of the intervention was evaluated after 12 weeks.ResultsThere were no significant differences in the baseline values of various parameters between the two groups. Exercise capacity (sit-to-stand test,handgrip,time to 10 sit-ups) significantly improved in the intervention group after 12 weeks (32.68 ± 8.32 vs 26.50 ± 6.83; 37.42 ± 10.12 vs 28.12 ± 8.51; 19.8 ± 5.40 vs 25.29 ± 7.18) (p < 0.05). In terms of the kidney disease quality of life (KDQOLTM) score, all other dimensions except sexual function, social functioning, burden of kidney disease and work status dimensions showed significant improvement compared to the baseline (p < 0.05). In the control group, only the dialysis staff encouragement (DSE) and patient satisfaction (PS) dimensions showed slight improvements compared to the baseline (p > 0.05). When compared with the control group, the intervention group showed significant improvements in 10 dimensions of exercise capacity and KDQOLTM scores for physical function, role-physical, general health, energy, symptom/problem list, sleep, DSE, pain, cognitive function, emotional well-being and patient PS after 12 weeks (61.30 ± 5.38 vs 42.98 ± 5.73; 57.50 ± 3.55 vs 50.70 ± 3.62) (p < 0.05). Some inflammatory markers, such as the levels of interleukin-6 and high-sensitivity C-reactive protein (30.29 ± 2.96 vs 17.65 ± 3.22; 8.93 ± 0.99 vs 3.02 ± 0.34), showed a decrease during the intervention, while albumin and prealbumin levels were significantly increased compared with the baseline (30.62 ± 1.65 vs 35.60 ± 1.68; 0.32 ± 0.05 vs 0.44 ± 0.07) (p < 0.05).ConclusionCombined intervention training can improve the motor ability and quality of life of patients with sarcopenia within a short period of time.

CARDIAC REHABILITATION AND PSYCHOLOGICAL TREATMENT: CONTRASTS IN ANXIETY, DEPRESSION AND ILLNESS PERCEPTION LEVELS

Abstract Background Investigating the relationship between psychological factors and cardiovascular diseases (CVD) has long been a focal point of previous research. Researchers have primarily focused on identifying possible predictive factors for CVD’s development and examining patients’ responses during acute or chronic phases, but less is known about the role of cardiac rehabilitation and the types of psychological treatments on patients’ psychological status. Aims The aim of this study is to compare anxiety, depression, and illness perception levels of patients affected by different cardiovascular diseases at the beginning (t0), at the end (t1), and three months after a cardiac rehabilitation program (t2) in which patients were involved in three different types of psychological treatments: psychoeducational intervention group, progressive muscle relaxation training integrated with Jacobson‘s technique and imaginative stabilization techniques, individual counseling. Methods In this study were involved patients with recent episodes of Acute Coronary Syndrome (ACS), heart failure (HF) or cardiac surgery undergoing cardiac rehabilitation between January 2023 and August 2023 at ASST Bergamo Est. To assess anxiety, depression and illness perception levels of participants we used self–report questionnaires that included the Hospital Anxiety and Depression Scale (HADS) and the Brief Illness Perception Questionnaire (Brief–IPQ). Patients could be assigned to different psychological treatments based on their clinical condition. Results The study involved 181 participants, namely N=36 ACS cases (19.9%), N=25 CHF (13.8%), and N=120 cardiac surgery (66.3%). As shown in Table 1, males were 71.3% (N=129) and the average age was 65.96 years old (SD=11.904). One hundred–sixty einght patients participated in psychoeducational intervention group, 120 in relaxation training, and 35 in individual counseling. Statistically significant differences in anxiety, depression, and illness perception levels were observed at the program‘s initiation (t0) and upon completion (t1 and t2) in relation to the psychological treatments: individual counseling had a better impact on levels of anxiety and depression and on the development of a more adequate perception of illness. Conclusions The type of psychological treatment during cardiac rehabilitation appears to give different results in terms of psychological status, self–care and disease management of patients.

A Bibliometric Study on The Application of Progressive Muscle Relaxation Training in The Nursing Field in China

Objective: To systematically analyze the research status and application of progressive muscle relaxation training (PMRT) in the nursing field in China, and provide a reference basis for scientific research in this field. Methods: The bibliometric method was adopted in “progressive muscle relaxation training” or “PMRT,” and “nursing.” The established database was included in the China National Knowledge Infrastructure (CNKI) and the Wanfang Medical Network. The relevant articles in the Chinese Science and Technology Periodical Database (VIP) were analyzed. Results: A total of 169 literatures were included. The journals, years, and regions of literature publication were uneven, mainly originating from the eastern region (43.19%), and listed the application of progressive muscle relaxation training in the field of nursing in China. Intervention literature information was mainly dominated by experimental studies (97%). Conclusion: The related research and application of progressive muscle relaxation training in nursing in China is increasing, but there is a lack of objective evaluation of outcome indicators and a short intervention period. Further research should be conducted in the future to effectively guide the development of PMRT in the field of nursing in China.

A randomized controlled trial of effects of sleep hygiene training and progressive muscle relaxation training in children with ADHD

ObjectSleep problems often accompany ADHD and negatively affect ADHD symptoms, however, there are not enough intervention studies on sleep interventions in children with ADHD. The present study investigated the effects of sleep hygiene training (SH) and progressive muscle relaxation exercises (PMR) in children with ADHD. Method: 57 children aged 6–12 years with ADHD were randomly assigned to the SH and SH + PMR groups and completed the intervention consisting of group training and eight weeks of telephone interviews. The effects of both intervenitons were evaluated via parent, child and clinician report scales and neuropsychological tests. Results: Both interventions resulted in significant positive changes in child sleep, ADHD symptoms, functioning, neuropsychological tests and parental sleep quality. Significant differences were found between the interventions in selective attention, peer problems and anxiety scores in favor of the SH + PMR group. Conclusion: SH may have positive effects on various clinical parameters as well as sleep problems in children with ADHD. Addition of PMR to SH may lead to further improvements in anxiety, peer problems and selective attention. SH and PMR may be a useful tool in the clinical management of children with ADHD with sleep problems.

Effect of online health training/counseling and progressive muscle relaxation exercise on postpartum depression and maternal attachment: A randomized controlled trial.

To evaluate the effect of online health training/counseling and a progressive muscle relaxation exercise (PMRE) program on postpartum depression and maternal attachment. The present study was a randomized, controlled, experimental trial. Participants were asked to complete the Prenatal Attachment Inventory (PAI) and the Edinburgh Postpartum Depression Scale (EPDS) at 35 weeks of pregnancy. Group assignment was done by stratified block randomization according to EPDS score (0-9, 10-30) and parity. Women in the experimental group received training in progressive muscle relaxation, postpartum depression, and maternal attachment via online video calls twice a week starting at 36-37 weeks of pregnancy. They were asked to complete the PMRE program from 36 weeks of pregnancy until 6 months postpartum, and online counseling was provided throughout this period. Participants completed the Maternal Postpartum Attachment Scale (MPAS) and the EPDS at 6 weeks postpartum. Mean PAI score was 64.24 ± 9.61 in the experimental group before the intervention and 62.14 ± 10.13 in the control group. The mean EPDS score of the experimental group was 9.12 ± 5.05 and the mean score of the control group was 9.77 ± 6.30 (P > 0.05). The mean MPAS score after the intervention was 13.92 ± 5.54 in the experimental group and 17.51 ± 6.12 in the control group. The mean EPDS score of the experimental group was 3.40 ± 3.00 and the mean score of the control group was 11.40 ± 5.91 (P < 0.05). Online health training/counseling and PMRE reduce the risk of postpartum depression and increase maternal attachment.

The Current Application Status of Progressive Muscle Relaxation Training in Clinical Nursing Practice

The Current Application Status of Progressive Muscle Relaxation Training in Clinical Nursing Practice

2023 MASCC/ESMO consensus antiemetic guidelines related to integrative and non-pharmacological therapies.

Review the literature to propose suggestions or recommendations for controlling nausea and vomiting through integrative and non-pharmacological treatments for the MASCC/ESMO 2023 update of its antiemetic guidelines. The authors identified available systematic reviews and/or meta-analyses for 12 integrative therapies, including acupressure, acupuncture, auricular therapy, electrical stimulation of point PC6, ginger use(i.e., Zingiber officinale), guided imagery, hypnosis, inhalation aromatherapy, music therapy, food-based interventions, progressive muscle relaxation, and reflexology. Reviews were assessed for quality through the AMSTAR2 tool. A consensus committee reviewed recommendations as per MASCC/ESMO established processes. Thirty-nine systematic reviews and/or meta-analyses were used. There were major methodological flaws for many of thetrials used as the bases for the reviews. No recommendation for ingested ginger could be made because of conflicting evidence. Recommendations were possible for acupuncture/electroacupuncture treatments, food-based interventions, and progressive muscle relaxation training alone or combined with guided imagery. No recommendations could be reached for a number of food-based approaches, inhalation aromatherapy, hypnosis in adults, music therapy, and reflexology. While a limited number of suggestions are provided, there is a need for significantlyhigher quality trials in many of the therapeutic approaches assessed, before stronger recommendations and a wider range of approaches are made.

Effectiveness and mediators of change of an online CBT intervention for students with adjustment disorder—study protocol for a randomized controlled trial

BackgroundAdjustment problems and disorders are highly prevalent among university students worldwide. These problems can cause significant interference in academic and social functioning and increase vulnerability to other mental health disorders. Unfortunately, only half of students in need receive psychological help. Furthermore, few studies have evaluated psychological interventions for adjustment disorders in students. New, more scalable forms of treatment for students with an adjustment disorder need to be developed, evaluated, and implemented. The study aims to determine the effectiveness of an online transdiagnostic cognitive behavioural intervention for students experiencing adjustment disorder and to assess mediators of change.Method/designIn this three-arm randomized controlled trial, we plan to recruit 214 Polish students diagnosed with an adjustment disorder. Participants who meet initial eligibility criteria will be randomly assigned to one of three 6-week conditions: (1) online cognitive behavioural therapy intervention based on an existing, empirically supported transdiagnostic protocol, the unified protocol; (2) online progressive muscle relaxation training as an active control group; or (3) waiting-list control group. Both interventions are asynchronous, interactive, and include minimal amount of therapist support. Assessments will consist of self-report questionnaires, daily diary measures, and neurocognitive tasks for evaluating cognitive functioning. These will be conducted at baseline, post-treatment, and 1-month follow-up. Daily diary measures will be taken during the first and last week of treatment (or waitlist period). Primary outcome measures will include adjustment disorder severity; secondary outcome measures will consist of other negative (psychopathology: depression, anxiety, and stress) and positive (life satisfaction) indexes of mental health as well as process measures (e.g. mindfulness, experiential avoidance, cognitive fusion).DiscussionTo our knowledge, the current study is the first to evaluate the effectiveness of a psychological intervention for students with adjustment disorder. Therefore, it may have important practical implications for students with this disorder. It can potentially guide the development of a scalable, validated treatment option.Trial registrationClinical Trials, NCT05768308, registered 14 March 2023, https://www.clinicaltrials.gov/ct2/show/NCT05768308

Smelling an odor present during PMR does not impact heart rate during a stressful cognitive task

AbstractPrevious research on the impact of odors on current emotional state has been mixed, with some studies finding odors can induce feelings of relaxation while others have not. The aim of Part 1 of the current study was to investigate whether a feeling of relaxation, measured by a self‐report positive and negative affect scale and heart rate (HR), could be associated with an odor after completing three supervised sessions of progressive muscle relaxation (PMR) training while wearing an odorized nasal clip. Although the Part 1 results revealed no differences in positive or negative affect or HR between participants who wore an odorized or non‐odorized nasal clip, the PMR training was effective in reducing HR and negative affect overall. The aim of Part 2 was to determine whether the PMR training sessions in Part 1, could help reduce an objective measure of stress (i.e., HR) during four conditions of a cognitively stressful task, with and without an odorized nasal clip. The results for Part 2 revealed there were no differences in HR between participants who trained with odorized or non‐odorized nasal clips in any of the four conditions. However, given no explicit tests of learned odor‐PMR associations were performed, the lack of group differences may be due to various reasons, including a reduction in any learned association before testing Part 2. In summary and contrary to the hypothesis, participants who completed PMR training with an odorized nasal clip did not demonstrate a lower HR during a stressful cognitive task while wearing the odorized nasal clip, compared to those who wore a non‐odorized nasal clip during PMR training. Future research on the association between odors and relaxation may benefit from adapting the training protocol to include more frequent or longer associations between the behavior and the odor.Practical ApplicationThe findings provide preliminary evidence that wearing an odorized nasal clip during light activities such as progressive muscle relaxation is tolerated well but further research exploring whether this pairing leads to feelings of relaxation when odors are presented alone is warranted.

Progressive Muscle Relaxation: Can it Reduce Competitive Anxiety?

The study purpose was to determine the effect of progressive muscle relaxation training on reducing competitive anxiety among shooting athletes. Materials and methods. An experimental approach with a pretest-posttest control group design was used in this study. The experiment was carried out eight times. A total of 12 athletes, 8 males and 4 females, who were shooting athletes, took part in this research. The athletes in this study, who joined the regional training center in East Java Province, Indonesia, ranged in age from 20 to 44 years. In this investigation, saturated samples, including those from all individuals, were used. Data were obtained from competitive anxiety scales during the pre- and post-test periods. Independent samples t-tests were used to assess the data. Results. The t-value for this study is -14,210, and the p-value is 0.001. These findings suggest that progressive muscle relaxation training reduces competitive anxiety in shooting athletes. The athlete’s awareness of the value of mental training contributes to reduction in competitive anxiety. This study has gained traction since athletes are aware of the value of preparing for training before competing because they attend and participate in the regional training center. Conclusions. Progressive muscle relaxation training can be used as an intervention to help shooting athletes reduce their competitive anxiety.

Effects of inpatient energy management education and high-intensity interval training on health-related quality of life in persons with multiple sclerosis: A randomized controlled superiority trial with six-month follow-up.

Fatigue is one of the most frequent symptoms in persons with multiple sclerosis (pwMS) and impacts health-related quality of life (HRQoL). A multidisciplinary rehabilitation approach is recommended for the treatment of fatigue in pwMS. However, high-quality evidence exists only for unimodal interventions, such as physical therapies/exercise or energy/fatigue management programmes. The primary objective of the current study was to test the hypothesis that a combination of inpatient energy management education (IEME) and high-intensity interval training (HIIT) is superior to a combination of progressive muscle relaxation (PMR) and moderate continuous training (MCT) for improving HRQoL at 6-month follow-up in fatigued pwMS. A randomized (1:1) controlled superiority trial with fatigued pwMS >18 years of age, with Expanded Disability Status Scale (EDSS) score ≤6.5, recruited at the Valens clinic, Switzerland. Participants in the experimental group performed IEME twice and HIIT 3 times per week and those in the usual care group performed PMR twice and MCT 3 times per week, during a 3-week inpatient rehabilitation stay. Primary outcome was HRQoL (Physical and Mental Component Scales of the Medical Outcome Study 36-item Short Form Health Survey (SF-36)), assessed at entry to the clinic (T0), after 3 weeks' rehabilitation (T1) and 4 (T2) and 6 (T3) months after T0. Secondary outcomes included SF-36 subscales, fatigue (Fatigue Scale for Motor and Cognitive Functions (FSMC)), mood (Hospital Anxiety and Depression Scale (HADS)), self-efficacy for performing energy conservation strategies (Self-Efficacy for Performing Energy Conservation Strategies Assessment (SEPECSA)), self-perceived competence in activities of daily living (Occupational Self Assessment (OSA)) and cardiorespiratory fitness (peak oxygen consumption (VȮ2peak)). Data were analysed using a mixed model for repeated measures approach. A total of 106 pwMS (age (years): 49.75 (9.87), 66% female, EDSS: 4.64 (1.32)) were recruited. There were no significant group×time interaction effects in the primary and secondary outcomes. There were significant between-group differences in the pairwise comparisons of the group×time interaction in favour of the IEME+HIIT group at: (i) T1 in cardiorespiratory fitness (p=0.011) and SEPECSA (p=0.032); (ii) T2 in SF-36 mental health subscale (p=0.022), HADS anxiety subscale (p=0.014) and SEPECSA (p=0.040); (iii) T3 in SF-36 physical functioning subscale (p=0.012) and SEPECSA (p=0.003). IEME+HIIT was not superior to PMR+MCT regarding the effects on HRQoL (SF-36 Physical and Mental Component Scales) at 6-month follow-up in pwMS. However, there were significant between-group differences in favour of IEME+HIIT in physical functioning and mental health (SF-36 subscales), anxiety (HADS), cardiorespiratory fitness (VȮ2peak) and self-efficacy (SEPECSA) at different measurement time-points that need to be considered in clinical practice.

Efficacy of immersive extended reality (XR) interventions on different symptom domains of schizophrenia spectrum disorders. A systematic review.

Extended reality (XR) is an umbrella term for virtual reality (VR) and augmented reality (AR), both novel vectors for therapeutic intervention modalities. In VR, head-mounted devices (HMD) allow interaction with three-dimensional virtual environments and simulated avatars, while AR overlaps virtual, simulated objects to observe physical reality. Treatment through immersive VR has been studied in psychiatry, including patients suffering from schizophrenia spectrum disorders, while there has not been much attention to AR technologies in psychiatry. Our systematic review aimed to examine the currently available literature regarding the treatment efficacy of immersive VR or AR technologies on different symptom domains of schizophrenia spectrum disorders, screen for potential adverse effects, and gather data on the technological and human resource requirements of such interventions to help guide future research. We conducted a systematic literature review with database searches carried out between 9/2021 and 8/2022 through PubMed, Scopus, EBSCOhost Academic Search Premier, and Web of Science. We identified 2,157 records, 214 were assessed further for eligibility and 12 met inclusion criteria. All included articles studied immersive VR and none used AR technology. Included studies were heterogenous in nature, including AVATAR therapy (3) and CBT-based (5) VR interventions, as well as cognitive (2), social (1), and relaxation (1) training through VR. The comparison groups were either passive controls (waitlist and treatment as usual), therapeutic interventions (CBT and Integrated psychological treatment), passive VR environments, or traditional, comparable, non-virtual treatment modalities (social roleplay and progressive muscle relaxation training). Pooled together, the included studies on VR show positive treatment effects in all major symptom domains of schizophrenia spectrum disorders with hardly any adverse effects related to the intervention modalities. In this review, we have showcased how different symptom domains can be targeted through VR interventions, highlighting VR as a potential new vector for a diverse range of psychosocial therapeutic modalities that allow for completely new possibilities in the treatment of schizophrenia spectrum disorders. VR technology still requires more research and validation. Our review also shows that there are currently no studies examining AR technology in the treatment of schizophrenia spectrum disorders, indicating a distinctive research gap.

The application of virtual reality exposure versus relaxation training in music performance anxiety: a randomized controlled study

BackgroundPerformance anxiety is the most frequently reported anxiety disorder among professional musicians. Typical symptoms are - on a physical level - the consequences of an increase in sympathetic tone with cardiac stress, such as acceleration of heartbeat, increase in blood pressure, increased respiratory rate and tremor up to nausea or flush reactions. These symptoms can cause emotional distress, a reduced musical and artistical performance up to an impaired functioning. While anxiety disorders are preferably treated using cognitive-behavioral therapy with exposure, this approach is rather difficult for treating music performance anxiety since the presence of a public or professional jury is required and not easily available. The use of virtual reality (VR) could therefore display an alternative. So far, no therapy studies on music performance anxiety applying virtual reality exposure therapy have investigated the therapy outcome including cardiovascular changes as outcome parameters.MethodsThis mono-center, prospective, randomized and controlled clinical trial has a pre-post design with a follow-up period of 6 months. 46 professional and semi-professional musicians will be recruited and allocated randomly to an VR exposure group or a control group receiving progressive muscle relaxation training. Both groups will be treated over 4 single sessions. Music performance anxiety will be diagnosed based on a clinical interview using ICD-10 and DSM-5 criteria for specific phobia or social anxiety. A behavioral assessment test is conducted three times (pre, post, follow-up) in VR through an audition in a concert hall. Primary outcomes are the changes in music performance anxiety measured by the German Bühnenangstfragebogen and the cardiovascular reactivity reflected by heart rate variability (HRV). Secondary outcomes are changes in blood pressure, stress parameters such as cortisol in the blood and saliva, neuropeptides, and DNA-methylation.DiscussionThe trial investigates the effect of VR exposure in musicians with performance anxiety compared to a relaxation technique on anxiety symptoms and corresponding cardiovascular parameters. We expect a reduction of anxiety but also a consecutive improvement of HRV with cardiovascular protective effects.Trial registration: This study was registered on clinicaltrials.gov.
