A multimodal dataset for investigating working memory in presence of music: a pilot study.

Introduction: Decoding an individual's hidden brain states in responses to musical stimuli under various cognitive loads can unleash the potential of developing a non-invasive closed-loop brain-machine interface (CLBMI). To perform a pilot study and investigate the brain response in the context of CLBMI, we collect multimodal physiological signals and behavioral data within the working memory experiment in the presence of personalized musical stimuli. Methods: Participants perform a working memory experiment called the n-back task in the presence of calming music and exciting music. Utilizing the skin conductance signal and behavioral data, we decode the brain's cognitive arousal and performance states, respectively. We determine the association of oxygenated hemoglobin (HbO) data with performance state. Furthermore, we evaluate the total hemoglobin (HbT) signal energy over each music session. Results: A relatively low arousal variation was observed with respect to task difficulty, while the arousal baseline changes considerably with respect to the type of music. Overall, the performance index is enhanced within the exciting session. The highest positive correlation between the HbO concentration and performance was observed within the higher cognitive loads (3-back task) for all of the participants. Also, the HbT signal energy peak occurs within the exciting session. Discussion: Findings may underline the potential of using music as an intervention to regulate the brain cognitive states. Additionally, the experiment provides a diverse array of data encompassing multiple physiological signals that can be used in the brain state decoder paradigm to shed light on the human-in-the-loop experiments and understand the network-level mechanisms of auditory stimulation.

Integrative Review of Music and Music Therapy Interventions on Functional Outcomes in Children with Acquired Brain Injury.

Acquired brain injury (ABI) can result in a multitude of impairments to physical, cognitive, communicative, psychological, and psychosocial functioning. Music interventions are emerging as a valuable form of intervention in the rehabilitation of children with ABI, stimulating brain functions involved in movement, cognition, speech, emotions, and sensory perceptions. To date, the literature detailing the impact of music and music therapy interventions on functional outcomes in children with ABI has not been reviewed systematically. To address this, Whittemore and Knafl's five-stage integrative review framework was employed, which includes (a) problem identification, (b) literature search, (c) data evaluation, (d) data analysis and synthesis, and (e) presentation of the findings. A total of 388 articles were retrieved, and 8 studies met the inclusion criteria. Analysis and synthesis resulted in 3 overarching themes: outcomes of using music therapy in pediatric ABI, music therapy as a motivator in pediatric ABI rehabilitation, and collaboration. The review highlights the pivotal role of music as a motivational catalyst that promotes adherence to rehabilitative intervention. Nevertheless, it underscores a significant gap in empirical research within the field, emphasizing the necessity for larger, more rigorous studies.

Simultaneous cannabis and psychedelic use among festival and concert attendees in Colorado: characterizing enhancement and adverse reactions using mixed methods.

BACKGROUND: Most studies examining the simultaneous use of cannabis with other drugs have focused on cannabis and alcohol, with fewer studies examining simultaneous use of cannabis with other drugs. The United States is currently experiencing an upward trend in psychedelic use and there is an increasing need to characterize cannabis and psychedelic drug interactions to best inform public health recommendations. MATERIALS AND METHODS: A mixed methods field study design was used to survey participants (N = 128) on their lifetime co-use of cannabis with other drugs. Participants who reported lifetime co-use of cannabis and psychedelics (N = 63) were then asked open-ended questions about their most recent simultaneous co-use experience (i.e., how cannabis enhanced their psychedelic experience and whether they experienced any adverse reactions). We conducted a thematic analysis of responses describing how cannabis enhanced the psychedelic experience (N = 54). However, due to low response rate for participants reporting an adverse reaction (N = 7, 11.1%), responses to this question were not analyzed thematically and are instead presented individually. RESULTS: Themes included tension reduction and balancing of drug effects (N = 27, 50%), enhancement to psychological processes (N = 11, 20.4%), intensified psychedelic drug effects (N = 12, 22.2%), enhanced psychedelic come-down experience (N = 8, 14.8%), and overall ambiguous enhancement (N = 7, 13%). Among participants reporting an adverse reaction, individual responses included increased anxiety and intensity of the experience, decreased sociability, increased negative affect, sleepiness, disassociation, and confusion. CONCLUSION: Additional research is warranted to better characterize cannabis and psychedelic drug interactions to best inform public health recommendations.

Technology-Based Music Interventions to Reduce Anxiety and Pain Among Patients Undergoing Surgery or Procedures: Systematic Review of the Literature.

BACKGROUND: Hospitalized patients undergoing surgery or procedures may experience negative symptoms. Music is a nonpharmacological complementary approach and is used as an intervention to reduce anxiety, stress, and pain in these patients. Recently, music has been used conveniently in clinical situations with technology devices, and the mode of providing music is an important factor in technology-based music interventions. However, many reviews have focused only on the effectiveness of music interventions. OBJECTIVE: We aimed to review randomized controlled trials (RCTs) of technology-based music interventions for reducing anxiety and pain among patients undergoing surgery or procedures. We examined the clinical situation, devices used, delivery methods, and effectiveness of technology-based music interventions in primary articles. METHODS: The search was performed in the following 5 electronic databases: PubMed, MEDLINE (OvidSP), CINAHL complete, PSYCINFO, and Embase. This systematic review focused on technology-based music interventions. The following articles were included: (1) RCTs, (2) studies using interactive technology (eg, smartphones, mHealth, tablets, applications, and virtual reality), (3) empirical studies reporting pain and anxiety outcomes, and (4) English articles published from 2018 to 2023 (as of January 18, 2023). The risk of bias was assessed using the Cochrane Risk of Bias tool version 2. RESULTS: Among 292 studies identified, 21 met the inclusion criteria and were included. Of these studies, 9 reported that anxiety scores decreased after music interventions and 7 reported that pain could be decreased before, during, and after procedures. The methodology of the music intervention was important to the results on anxiety and pain in the clinical trials. More than 50% (13/21, 62%) of the studies included in this review allowed participants to select themes themselves. However, it was difficult to distinguish differences in effects depending on the device or software used for the music interventions. CONCLUSIONS: Technology-based music interventions could help reduce anxiety and pain among patients undergoing surgery or procedures. The findings of this review could help medical teams to choose a practical methodology for music interventions. Future studies should examine the effects of advanced technology-based music interventions using smart devices and software that promote interactions between medical staff and patients.

Music-Making and Depression and Anxiety Before and During the COVID-19 Pandemic-Results From the NAKO Cohort Study in Germany.

Objectives: To investigate the association of musical activity with mental health during the COVID-19 pandemic. Methods: A total of 3,666 participants reported their musical activity before and mental health indicators before and during the pandemic. Depression was assessed with the Patient Health Questionnaire, anxiety with the Generalized Anxiety Disorder scale. The association between mental health scores and musical activities was investigated using linear regression. Results: Within the last 12 months, 22.1% of the participants reported musical activity (15.1% singing, 14.5% playing an instrument). Individuals with frequent singing as their main musical activity had higher scores before the pandemic than non-musicians and the worsening during the pandemic was more pronounced compared to non-musicians. Instrumentalists tended to have slightly lower scores than non-musicians indicating a possible beneficial effect of playing an instrument on mental health. Conclusion: The pandemic led to a worsening of mental health, with singers being particularly affected. Singers showed poorer mental health before the pandemic. The tendency for instrumentalists to report lower depression scores compared to non-musicians may support the hypothesis that music-making has a beneficial effect on health.

The double mediating effect of stress regulation and life satisfaction on music use as a coping mechanism and happiness in Chinese older adults during the COVID-19 pandemic.

BACKGROUND: This study investigated the relationship between music use as a coping mechanism and subjective happiness among Chinese older adults (COAs) during Coronavirus disease 2019 (COVID-19); it also focused on the mediating effect of stress regulation by music and life satisfaction in this relationship. METHODS: Participants were 329 male and female Chinese adults aged 60 years or older. Data were collected using the Sojump application for an online survey. The double mediating effect was analyzed using PROCESS Macro 3.5 Model 6. RESULTS: The results revealed that music use as a coping mechanism and stress regulation by music were not significantly correlated with subjective happiness of COAs, whereas these were positively correlated with their life satisfaction. Additionally, life satisfaction of COAs was positively correlated with subjective happiness. Stress regulation by music and life satisfaction completely mediated the relationship between music use as a coping mechanism and subjective happiness of COAs during COVID-19. In the double mediation model, music use as a coping mechanism positively influenced stress regulation by music (ß = 0.704), stress regulation by music positively influenced life satisfaction (ß = 0.162), and life satisfaction positively influenced subjective happiness (ß = 0.498). CONCLUSION: Therefore, music can promote happiness in COAs in stressful situations through stress regulation and life satisfaction.

The effects of music-based interventions on behavioural and psychological symptoms of people living with dementia: a systematic review and network meta-analysis protocol.

OBJECTIVES: People living with dementia often experience behavioural and psychological symptoms of dementia (BPSD), which severely affect their well-being during the course of the disease. Particularly for BPSD outcomes, there is a high demand for increasing the evidence-based knowledge of non-pharmacological approaches, such as music-based interventions. Although previous reviews emphasize the potential effects of music-based interventions in people with dementia, they cover a wide range of different interventions and outcomes. METHOD: Therefore, this systematic review (SR) and network meta-analysis (NMA) aims to not only investigate the efficacy of music-based interventions on BPSD, but also to compare the impact of different types of music-based interventions on outcomes. Preferred reporting items for SR and meta-analysis protocols (PRISMA-P) and the PRISMA NMA extension were followed. Several databases will be searched from inception to the date the search will be performed, for relevant randomized or non-randomized controlled trials comparing a music-based intervention with treatment as usual, active controls, or another music-based intervention. Multivariate pairwise meta-analyses will be conducted for each outcome. NMA based on a frequentist random-effects model will be used to estimate the comparative effects of each type of music-based intervention and related components across outcomes. Heterogeneity will be investigated by meta-regression models. CONCLUSION: Based on our knowledge, this may be the first SR and NMA study to compare the efficacy of different types of music-based interventions. In addition, combined with our multivariate analysis approach, it will allow us to identify potential effect modifiers in music-based intervention for treating BPSD.

Effects of brisk walking with or without music on body composition, standing balance, cardiovascular parameters, and salivary biomarkers in older women.

This study aimed to assess and compare changes in body composition, standing balance, cardiovascular parameters, and salivary biomarkers, particularly salivary antioxidant status, after brisk walking training with or without music in older women. Twenty-four subjects were randomly assigned to brisk walking groups: with music (BWM) (n=12) or without music (BW) (n=12). Eighteen subjects completed the exercise training (9 in each group), and their data were used for analysis. The research protocols were classified into three phases: pretraining phase, training phase, and posttraining phase, while the data collection was divided into four sessions: resting condition, during treadmill exercise testing, immediately posttreadmill exercise testing, and 5-min posttreadmill exercise testing defined as after the cool-down session. The results showed that 8 weeks of home-based brisk walking with or without music did not improve standing balance, blood pressure, salivary biomarkers including total protein concentration, and antioxidant status but maintained or prevented the decline of these parameters. Only the BWM group reduced fat mass relative to increasing fat-free mass (P<0.05) and improved recovery heart rate (P<0.05) by modifying cardiac autonomic control in posttreadmill exercise testing. Therefore, brisk walking with preferred music can be a tool to delay the progression of cardiovascular dysfunction in older women. A longer duration of the exercise program and larger groups of participants are needed for further investigation of brisk walking with or without music on physiological and biochemical changes.

A Remotely Delivered, Personalized Music Therapy Pilot Intervention for Lonely Older Adults During the Covid-19 Pandemic.

Introduction: This study investigated a remotely delivered, therapist-facilitated, personalized music listening intervention for community-dwelling older adults experiencing loneliness during the Covid-19 pandemic. We assessed its feasibility and individuals' experiences of social connection and emotional well-being during the intervention. Methods: Ten cognitively unimpaired older adults who endorsed loneliness completed eight weekly sessions with a board-certified music therapist via Zoom. Participants were guided in developing two online personalized music playlists and were asked to listen to playlists for at least one hour daily. Feasibility metrics were attendance, accessibility, and compliance rates. Post-study interview responses were analyzed using a rapid qualitative methodology. Exploratory pre- and post-study measures of loneliness and other aspects of psychological well-being were obtained using validated questionnaires. Results: Ten participants (mean age 75.38 [65 to 85] years, 80% women) were enrolled from March to August 2021. Attendance and compliance rates were 100% and the accessibility rate was 90%. Most participants associated music with positive memories before the program and many reported that the intervention prompted them to reconnect with music or listen to music with greater intention. They cited increased connection from interacting with the music therapist and the music itself, as well as specific positive emotional impacts from integrating music into their daily lives. Median pre- to post-questionnaire measures of psychological function all changed in an improved direction. Discussion: Remotely delivered music therapy may be a promising intervention to promote regular music listening and socioemotional well-being in lonely older adults.

Affective music during episodic memory recollection modulates subsequent false emotional memory traces: an fMRI study.

Music is a powerful medium that influences our emotions and memories. Neuroscience research has demonstrated music's ability to engage brain regions associated with emotion, reward, motivation, and autobiographical memory. While music's role in modulating emotions has been explored extensively, our study investigates whether music can alter the emotional content of memories. Building on the theory that memories can be updated upon retrieval, we tested whether introducing emotional music during memory recollection might introduce false emotional elements into the original memory trace. We developed a 3-day episodic memory task with separate encoding, recollection, and retrieval phases. Our primary hypothesis was that emotional music played during memory recollection would increase the likelihood of introducing novel emotional components into the original memory. Behavioral findings revealed two key outcomes: 1) participants exposed to music during memory recollection were more likely to incorporate novel emotional components congruent with the paired music valence, and 2) memories retrieved 1 day later exhibited a stronger emotional tone than the original memory, congruent with the valence of the music paired during the previous day's recollection. Furthermore, fMRI results revealed altered neural engagement during story recollection with music, including the amygdala, anterior hippocampus, and inferior parietal lobule. Enhanced connectivity between the amygdala and other brain regions, including the frontal and visual cortex, was observed during recollection with music, potentially contributing to more emotionally charged story reconstructions. These findings illuminate the interplay between music, emotion, and memory, offering insights into the consequences of infusing emotional music into memory recollection processes.

Neural correlates of musical timbre: an ALE meta-analysis of neuroimaging data.

Timbre is a central aspect of music that allows listeners to identify musical sounds and conveys musical emotion, but also allows for the recognition of actions and is an important structuring property of music. The former functions are known to be implemented in a ventral auditory stream in processing musical timbre. While the latter functions are commonly attributed to areas in a dorsal auditory processing stream in other musical domains, its involvement in musical timbre processing is so far unknown. To investigate if musical timbre processing involves both dorsal and ventral auditory pathways, we carried out an activation likelihood estimation (ALE) meta-analysis of 18 experiments from 17 published neuroimaging studies on musical timbre perception. We identified consistent activations in Brodmann areas (BA) 41, 42, and 22 in the bilateral transverse temporal gyri, the posterior superior temporal gyri and planum temporale, in BA 40 of the bilateral inferior parietal lobe, in BA 13 in the bilateral posterior Insula, and in BA 13 and 22 in the right anterior insula and superior temporal gyrus. The vast majority of the identified regions are associated with the dorsal and ventral auditory processing streams. We therefore propose to frame the processing of musical timbre in a dual-stream model. Moreover, the regions activated in processing timbre show similarities to the brain regions involved in processing several other fundamental aspects of music, indicating possible shared neural bases of musical timbre and other musical domains.

Playing with data differently: engaging with autism and gender through participatory arts/music and a performative framework for analysis.

There are increasing demands for Participatory Arts-Based (PAB) programs involved in health research to better evidence outcomes using robust quantitative evaluation methodologies taken from science, such as standardized questionnaires, to inform commissioning and scale-up decisions. However, for PAB researchers trying to do this, barriers arise from fundamental interdisciplinary differences in values and contexts. Researchers are required to navigate the tensions between the practice-based evidence produced by the arts and the evidence-based practice sought by psychologists. Consequently, there is a need for interdisciplinary arts-science collaborations to produce alternative methods of evaluation that are better aligned to PAB approaches, and which combine systematic rigor with a sensitivity to the values, contexts and strengths of this approach. The current article centers on the development of an alternative transdisciplinary analytic tool, the Participatory arts Play Framework (PP-Framework), undertaken as part of an arts-psychology collaboration for a UK AHRC-funded PAB research project: Playing A/Part: Investigating the identities and experiences of autistic girls. We present details of three stages in the development of the PP-Framework: 1. preliminary emergence of the framework from initial video analysis of observational data from participatory music and sound workshops run for 6 adolescent autistic girls (aged 11-16); 2. identification and application of modes of engagement; and 3. further testing of the framework as an evaluation tool for use in a real-world setting, involving professional musicians engaged in delivery of a creative music project at a center for homeless people. The PP-Framework maps types of participation in terms of performative behaviors and qualities of experience, understood as modes of play. It functions as a vehicle for analyzing participant engagement, providing a tool predicated on the processes of working in creative participatory contexts while also being sensitive to the esthetic qualities of what is produced and capable of capturing beneficial changes in engagement. It offers a conceptual approach for researchers to undertake observation of participatory arts practices, taking account of embodied engagement and interaction processes. It is informed by understandings of autistic performativity and masking in conjunction with an ecological understanding of sense making as being shaped by environments, social relations and sensing subjectivity. The framework has the potential to be a bi-directional tool, with application for both practitioners and participants.

The effectiveness of live music intervention on psychological distress among adolescent and young adult patients undergoing hematopoietic stem cell transplantation.

OBJECTIVE: To explore the effects of live music to decrease psychological distress in adolescent and young adult (AYA) patients undergoing hematopoietic stem cell transplantation (HSCT). METHOD: A quasi-experimental study was conducted. Sixty patients undergoing HSCT were divided into two groups, receiving either 4 week of live music (n = 31) or standard care (n = 29). Psychological distress, anxiety, the severity of symptom clusters and symptom interference were measured. RESULTS: When compared with the immediately and 1 month after intervention, patients in LM intervention group had significantly lower psychological distress and anxiety level than wait-list group. AYA undergoing HSCT reported significantly milder general symptom cluster and neurological symptom cluster at T3 than at baseline. CONCLUSIONS: Live music intervention showed a positive effect on relieving psychological distress and anxiety in AYA patients undergoing HSCT. However, further researches are warranted to explore the effects of live music intervention on symptom cluster.

Effects of background music on numerical and spatial location working memory: differences between extraverts and introverts.

This experimental research explored background music's influence on the performance of numerical and spatial location working memory of extraverts and introverts. Sixty participants (30 extraverts and 30 introverts) were asked to complete numerical and spatial location working memory tests, under the conditions of background music and silence. Results showed a main negative effect of background music on the participants' performance of spatial location working memory. A significant interaction effect between music and personality (extroversion and introversion) on this performance was also observed. It revealed that a more negative effect of music in introverts as compared with extroverts. In contrast, no main or interaction effect was observed for the performance of numerical working memory. According to the influence of music on working memory, introversion-extraversion personality factors of workers such as cashiers or drivers require consideration.

This experimental study explored the influence of background music on the performance of numerical and spatial location working memory of extraverts and introverts. Results showed that the interaction effect between music and personality (extroversion and introversion) on spatial location working memory performance was significant. In contrast, no main or interaction effect was observed for the performance of numerical working memory.

An Intergenerational Telehealth Music Therapy Group Intervention to Improve Grandparents' Meaning in life.

The lockdown policies in Israel during the COVID-19 pandemic hampered familial grandparents-grandchildren relations. There is initial evidence that older adults' meaning in life and will-to-live decreased. Grandparents could no longer meet their grandchildren in person. In response, we utilized an intergenerational telehealth music therapy group intervention during the onset of the COVID-19 pandemic. Forty-four pairs of grandparents and grandchildren enrolled in a quasi-experimental study with an intervention and waitlist control group. Twenty-one pairs of grandparents-grandchildren participated in a weekly virtual group music therapy intervention (via Zoom) for 8 weeks (experimental group) and the remainder were waitlisted and received no intervention (control group). Participants in both groups completed the same questionnaires in parallel before and after the intervention. The grandparents' meaning in life, will-to-live and behavioral grandparenthood increased compared to no change observed in the control group. Further research with randomized-controlled treatment is recommended.

The clinical effects of Orff music therapy on children with autism spectrum disorder: a comprehensive evaluation.

Objective: This study aimed to investigate the clinical effects of Orff music therapy on children with Autism Spectrum Disorder (ASD) from the perspectives of parents, evaluators, and therapists. Methods: 93 children with ASD aged 3-6 years participated in the study. They were divided into an observation group (n = 48) receiving comprehensive rehabilitation intervention including Orff music therapy, and a control group (n = 45) receiving only comprehensive rehabilitation intervention. The Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), and Psycho-educational Profile-3rd edition (PEP-3) were used for assessments before and after the intervention. Results: There were no significant demographic differences between the two groups. Both groups showed significant improvements in Sensory, Relating, Language, CVP, EL, RL, VMI, AE, SR, and CARS scores at T1, T2, and T3 (T1 vs. T2, T2 vs. T3, T1 vs. T3) (all p < 0.05). The observation group demonstrated significant changes in Body and Object use and FM, while the control group showed some changes in these domains. Social and self-help, GM, CMB, and CVB also significantly improved in both groups after 6 months of intervention (all p < 0.05). In terms of different time intervals, the observation group showed greater improvements in Sensory, Relating, Language, CARS scores, EL, RL, and SR compared to the control group (all p < 0.05). The improvement levels in Body and Object use, CVP, FM, VMI, and AE did not differ significantly between the two groups in the T1-T2 interval, but were significantly higher in the observation group in the T2-T3 and T1-T3 intervals (all p < 0.05). The magnitude of changes in Social and self-help, GM, CMB, and CVB did not differ significantly between the groups. Conclusion: Orff music therapy showed significant improvements in language expression, language comprehension, social skills, cognitive abilities, imitation abilities, emotional expression and fine motor in children with ASD. These findings provide support for the use of Orff music therapy as an effective intervention for children with ASD.

Quantifying Changes in Dexterity as a Result of Piano Training in People with Parkinson's Disease.

People with Parkinson's disease often show deficits in dexterity, which, in turn, can lead to limitations in performing activities of daily life. Previous studies have suggested that training in playing the piano may improve or prevent a decline in dexterity in this population. In this pilot study, we tested three participants on a six-week, custom, piano-based training protocol, and quantified dexterity before and after the intervention using a sensor-enabled version of the nine-hole peg test, the box and block test, a test of finger synergies using unidimensional force sensors, and the Quantitative Digitography test using a digital piano, as well as selected relevant items from the motor parts of the MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and the Parkinson's Disease Questionnaire (PDQ-39) quality of life questionnaire. The participants showed improved dexterity following the training program in several of the measures used. This pilot study proposes measures that can track changes in dexterity as a result of practice in people with Parkinson's disease and describes a potential protocol that needs to be tested in a larger cohort.

Does selective intraoperative music reduce pain following abdominal wall reconstruction? A double-blind randomized controlled trial.

PURPOSE: Although intraoperative music is purported to mitigate postoperative pain after some procedures, its application has never been explored in abdominal wall reconstruction (AWR). We sought to determine whether intraoperative music would decrease early postoperative pain following AWR. METHODS: We conducted a placebo-controlled, patient-, surgeon-, and assessor-blinded, randomized controlled trial at a single center between June 2022 and July 2023 including 321 adult patients undergoing open AWR with retromuscular mesh. Patients received noise-canceling headphones and were randomized 1:1 to patient-selected music or silence after induction, stratified by preoperative chronic opioid use. All patients received multimodal pain control. The primary outcome was pain (NRS-11) at 24 ± 3 h. The primary outcome was analyzed by linear regression with pre-specified covariates (chronic opioid use, hernia width, operative time, myofascial release, anxiety disorder diagnosis, and preoperative STAI-6 score). RESULTS: 178 patients were randomized to music, 164 of which were analyzed. 177 were randomized to silence, 157 of which were analyzed. At 24 ± 3 h postoperatively, there was no difference in the primary outcome of NRS-11 scores (5.18 ± 2.62 vs 5.27 ± 2.46, p = 0.75). After adjusting for prespecified covariates, the difference of NRS-11 scores at 24 ± 3 h between the music and silence groups remained insignificant (p = 0.83). There was no difference in NRS-11 or STAI-6 scores at 48 ± 3 and 72 ± 3 h, intraoperative sedation, or postoperative narcotic usage. CONCLUSION: For patients undergoing AWR, there was no benefit of intraoperative music over routine multimodal pain control for early postoperative pain reduction. TRIAL REGISTRATION: ClinicalTrials.gov: NCT05374096.

The impact of music on anxiety, pain, and blood pressure in ophthalmic surgery: A systematic review and meta-analysis.

OBJECTIVES: To evaluate the effectiveness of music therapy in reducing anxiety, pain, and vital sign changes in ophthalmic surgery patients. METHODS: An extensive search of databases, including PubMed, Embase, Cochrane, Web of Science, and Google Scholar, identified relevant studies up to Jan 2024. Selection of studies was conducted based on the PICOS criteria. The quality of methodology was assessed using the Cochrane risk-of-bias assessment tool and Review Manager 5.4. Meta-analysis comparing the control group and the music therapy group was performed using R and Stata/SE 15.1 random or fixed effects model. RESULTS: This meta-analysis included fifteen studies comprising 2098 participants. The analysis revealed that music therapy significantly reduced the risk of high anxiety levels as measured by Visual Analogue Scale (VAS) (I2 = 0 %, RR(95 %CI): 0.75(0.63, 0.88), p = 0.0006), indicating a substantial effect without heterogeneity. The Anxiety scores determined by State-Trait Anxiety Inventory-State (STAI-S) also showed a significant decrease (SMD(95 %CI): -0.75(-0.88, -0.61), p < 0.0001), albeit with moderate heterogeneity (I² = 36 %). Additionally, music therapy was associated with a reduction in intraoperative pain levels, with no observed heterogeneity (I2 = 0 %, SMD(95 %CI): -0.74(-0.93, -0.56), p < 0.0001). In contrast, music intervention did not significantly influence self-reported nervousness, relaxation, or satisfaction levels as determined by VAS. Regarding to physiological parameters, a marginal decrease in systolic blood pressure (SBP) was observed (SMD(95 %CI): -0.42(-0.79, -0.04), p = 0.0286), with considerable heterogeneity (I² = 92 %). Diastolic blood pressure (DBP) experienced a slight reduction (I² = 90 %, SMD(95 %CI): -0.45(-0.79, -0.11), p = 0.0088). However, no significant effect was observed on patients' heart rate (p = 0.0864). CONCLUSION: Music therapy effectively reduced anxiety and pain, and moderately improved vital signs in patients undergoing ophthalmic surgery, highlighting its role in enhancing patient well-being. Further in-depth RCTs are needed to confirm its efficacy.

The Added Effect of Music-Assisted Kangaroo Care Applied to Mothers with Premature Babies in the Intensive Care Unit on the Amount of Breast Milk, the Initiation Time of Breastfeeding, and Anxiety Level.

Background: The aim of this study is to determine the effect of music-assisted kangaroo care, applied to mothers with premature babies in the intensive care unit on the amount of breast milk, the initiation time of breastfeeding, and the level of anxiety. Methods: The study was carried out with mothers whose premature babies were hospitalized in the neonatal intensive care unit. The sample size of the study was 99 mothers. Results: 85.5% of the mothers were aged >35 years, 30.1% were high school graduates, 38.6% had equal income and expenses and 77.1% had a cesarean section. The state and trait anxiety levels of the mothers in the music assisted kangaroo care (MAKC), kangaroo care (KC), and control (C) groups decreased after the first day according to the follow-up times. The trait anxiety levels of the mothers in the MAKC group experienced on the first and sixth days were lower than those of the mothers in the KC and C groups, with the statistically significant differences (p < 0.05). It was found that the mothers in the MAKC group started breastfeeding earlier than those in the KC and C groups, and the difference was statistically significant (p < 0.05). Conclusion: A significant difference was found between the MAKC and KC groups and the control group in terms of an increase in the amount of milk, a decrease in trait anxiety levels, and early initiation of breastfeeding (p < 0.05).
