Effect of music on short-term pain perception during peripheral intravenous cannulation

Music has been investigated as a potential influence on exercise performance, perceived exertion, recovery, and sleep. However, studies vary in their interventions, populations, exercise contexts, and measured outcomes. This scoping review aimed to map experimental evidence on music interventions in resistance, isometric and handgrip, aerobic exercise, acute recovery, and sleep, and to identify evidence gaps. PubMed/MEDLINE, SPORTDiscus, Scopus, and Web of Science were searched for studies published between 1980 and October 2026. Eligible studies involved human participants, compared a music intervention with a control or alternative condition, and reported exercise performance, perceived exertion, psychological responses, physiological recovery, or sleep outcomes. Screening was conducted using Rayyan. Findings were synthesised descriptively across four domains. Thirty studies involving 1,183 participants were included. Studies were published between 1981 and 2021 and examined resistance exercise (n=11), isometric and handgrip exercise (n=8), aerobic exercise and acute recovery (n=7) and sleep (n=4). The evidence maps a broad range of music interventions and outcomes, with variable findings across exercise and sleep contexts. Research gaps include limited participant diversity and insufficient investigation of sleep and recovery in athletic populations. Further studies are needed to clarify how music characteristics, individual preferences, and task demands relate to outcomes.

ABSTRACT Low Back Pain (LBP) is a disease caused by non-ergonomic working conditions during manual handling activities. LBP is a leading cause of activity limitations, disability, inability and absenteeism from work. The aim of this study was to analyze ergonomic risk factors for LBP complaints and their relationship to the two in charcoal briquette manufacturing industry workers at PT. Arkelindo Bara Sejahtera. This study was quantitative with a cross-sectional approach. The study was conducted from June to November 2025. The population and sample were 183 and 151 workers, respectively. Research data was obtained from questionnaires, interviews, diagnoses, and direct on-site observations. Data analysis was conducted using univariate, bivariate, and multivariate methods. The results showed that as many as 64.2% of participants experienced complaints of severe LBP. It was also found that awkward postures, static work positions, repetitive movements and excessive force use were at risk of 62.9%, 70.2%, 73.5% and 57.6%, respectively. There is a relationship between awkward postures (p = 0.023, OR = 2.843), static work positions (p =0.004, OR = 3.875), repetitive movements (p = 0.000, OR = 6.013) and excessive force use (p = 0.003, OR = 4.178) and NBP complaints. The dominant ergonomic risk factor for LBP complaints is repetitive movements with an OR value of 6.013. This study indicates that repeated exposure to sitting or standing for more than half the working day, combined with awkward postures such as bending and twisting, were the dominant contributing factors to LBP. It is hoped that companies can implement ergonomic work positions to ensure worker comfort. Keywords: Charcoal Briquette Industry, Ergonomic Risks, Back Pain, Occupational Health.

Itu diharapkan bahwa perusahaan dapat menerapkan posisi kerja ergonomis agar pekerja nyaman saat bekerja. Kata Kunci: Industri Briket Arang, Risiko Ergonomi, Nyeri Punggung, Kesehatan Kerja.

This article sought to adapt and validate an instrument for the perception of management policies and practices aimed at higher education professors, since the available instruments were designed for organisations in general and do not address the particularities of academic work. The instrument was based on two scales already validated for Brazilian organisations, with the addition of items on research incentives, publication support and the teaching career. Content and criterion validity derived from the published origin of the items, complemented by prior definition of the constructs, peer review and pre-testing. A total of 386 professors from Brazilian public and private institutions took part, answering on an interval scale based on adverbs of quantity and frequency. Internal consistency reached a Cronbach's alpha of 0.956. Exploratory factor analysis, used for the statistical validation of the constructs defined a priori, retained six factors explaining 67.3% of the accumulated variance, with a sampling adequacy of 0.948. The expected dimensions were reproduced, and the added items formed a factor of their own. It is concluded that the adapted instrument is suitable for measuring teachers' perception of institutional management.

Perceptual expertise is widely assumed to refine multisensory perception, yet the empirical literature appears inconsistent. Trained musicians show narrower audiovisual temporal integration windows and quicker segregation, whereas experienced wine tasters seem more influenced by a wine's color in their aroma and flavor judgments than novices are. We argue that the inconsistency arises from a conflation of two formally distinct quantities: the prior probability that concurrent signals arise from a common source, and the coupling between the values of signals that share one. We present a generative model in which both are free parameters, along with channel precision and a decision criterion, that contains causal-inference and coupling-prior models as special cases. The model shows that the correlation between the values of two signals across an environment reflects only the product of the two priors, so that a correlation-tracking learner acquires the coupling when the signals always share a source, whereas separating the two priors requires representing causal structure; that binary common-source reports confound the common-cause prior with the decision criterion; that the coupling trades off against the measurement noise of the influencing channel unless its precision is measured independently; and that the two priors leave distinct signatures in how cross-modal influence varies with disparity. When the source is fixed, as for the color and odor of a wine, tighter coupling alone produces the conjunction of greater displacement by color and better discrimination between wines reported for experienced tasters, which no change in odor precision can produce. Simulations of a test battery combining continuous estimates, common-source reports and discrimination thresholds show that the parameters can be recovered, that a within-subject dissociation can be detected with conventional sample sizes under illustrative effect sizes, and that recovery fails in certain cases. The account yields a rule classifying environments by their base rate of common causation and their coupling strength, and the same ambiguity attends claims about altered multisensory processing in autism and aging. We also show that the most cited demonstration of expert susceptibility to color contains no expertise manipulation, and suggest that apparent expert biases may reflectwind calibration to real-world statistics.

Introduction Anticipating an opponent's actions is central to performance in team sports such as soccer, where a player must select the correct response within a fraction of a second. Perceptual-cognitive expertise in anticipation is well documented, but standard measures (response time, accuracy, or option choice) capture only the discrete response produced at a single moment and leave the preparatory processing that precedes it unobserved. Building on evidence that hand and cursor movements reveal cognition as it unfolds, the present study examined, as a proof of concept, whether continuous cursor tracking can read out the pre-response preparatory state in a sports anticipation task. Methods Twelve skilled soccer players and twelve novices watched soccer pass-course clips and anticipated which teammate would receive the ball by moving a cursor; the video was stopped at the final frame (the moment a response was required), and the same clips were repeated across three blocks. Two continuous measures were defined: the cursor's Euclidean distance to the correct receiver at response onset (a spatial index of where the participant was poised) and the increase in cursor velocity in the window immediately before response onset (a temporal index of the movement toward the response). Results Compared with novices, skilled players anticipated more accurately, were poised closer to the correct receiver, and showed a larger velocity increase; control analyses argued against the velocity difference being a by-product of the total amount of movement. In an exploratory analysis, the positional difference emerged across repeated presentations of the same clips and was largest in the final block. In addition, the velocity difference was already present in the first presentation, and no significant change across repeated presentations was detected. Discussion The pre-response preparatory state is observed in both a spatial aspect (where one is poised) and a temporal aspect (how one moves toward the response). Because in basic reaching research the position and the velocity of movement index different aspects of decision-making, capturing both under a single continuous measure (which discrete responses cannot) provides a basis for measuring the decision-making processes that underlie anticipation in sport.
