Using a 100-mm visual-analogue scale, twenty participants were classified as non-pain (NPD) and pain developers (PD; ≥10 mm). Tri-axial accelerometers measured sitting time and thorax, pelvis, and lumbar spine angles. Amplitude probability distribution functions were constructed for postures and movements. PD (n = 6) exhibited increases in pain daily, with partial or complete recovery overnight and full recovery over the weekend, hence pain did not accumulate. PD sat more than NPD (n = 14), exhibited decreased peak posterior pelvic tilt (10°) and thorax inclination (8°), and tended to demonstrate less frequent spine movements. To decrease the risk of pain with sitting, reducing seated time, reclining on the seatback, and promoting seated movements should be recommended. With habitual exposures, small differences between pain groups could suggest a pathway to sitting-related back pain over time.Practitioner Summary: The biomechanical link between habitual sitting and low back pain remains unclear. Activity, spine kinematics, and pain ratings were collected throughout a week of individuals' seated work at their own workstation. Small differences between those with and without transient low back pain could suggest a pathway to sitting-related back pain.","PeriodicalId":50503,"journal":{"name":"Ergonomics","volume":" ","pages":"1-14"},"PeriodicalIF":2.0,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143781721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The self-contained breathing apparatus (SCBA) provides isolation of the airway from the hazardous fireground. National standards limit SCBA weight, however, integration of additional features could result in an SCBA exceeding the current limit. The purpose of this study was to examine the effects of increased SCBA weight on firefighters' physiological responses, work output, dynamic stability, and comfort. Completion of simulated firefighting activities induced a strong physiological response. Peak oxygen consumption was higher with the lightest SCBA than the heaviest SCBA. Few other physiological differences were noted as SCBA weight increased. Importantly, increased SCBA weight resulted in significantly more negative perceptions by the firefighters and a trend towards significance for the duration of work time prior to reaching volitional fatigue. These results should be considered when assessing changes to existing SCBA weight limits.","PeriodicalId":50503,"journal":{"name":"Ergonomics","volume":" ","pages":"557-570"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11704086/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141555878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, feature extraction leads to the loss of valuable information and often results in binary classifications that lack specificity in the identification of optimum mental workload. This study investigates the feasibility of using raw physiological data (EEG, facial EMG, ECG, EDA, pupillometry) combined with Functional Data Analysis (FDA) to estimate the mental workload of human drivers. A driving scenario with five tasks was employed, and subjective ratings were collected. Results demonstrate that the FDA applied nine different combinations of raw physiological signals achieving a maximum 90% accuracy, outperforming extracted features by 73%. This study shows that the mental workload of human drivers can be accurately estimated without utilising burdensome feature extraction. The approach proposed in this study offers promise for mental workload assessment in real-world applications.","PeriodicalId":50503,"journal":{"name":"Ergonomics","volume":" ","pages":"602-618"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141749561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines the impact of motorised and non-motorised lifting devices on reducing physical stress during wheelchair transfers among nurses. Systematic electronic database searches were performed, and the review was prepared according to the PRISMA guidelines. The results of 20 studies on biomechanical stresses related to WMSDs were synthesised qualitatively, and 13 were analysed quantitatively using meta-analysis. Motorised lifting devices significantly decreased biomechanical stress among nurses [SMD -0.68; 95% CI -1.02 to -0.34], whereas non-motorised counterparts showed no significant change [SMD - 0.23; 95% CI -0.59 to 0.13]. This study underscores the effectiveness of motorised lifting devices in mitigating WMSD risk during wheelchair transfers. The findings provide practical guidance for hospital administrators, policymakers, and experts seeking suitable devices to prevent WMSDs in nursing professionals.Practitioner Summary: This study investigated the impact of motorised and non-motorised lifting devices on nurses during wheelchair transfers. Findings revealed that motorised devices significantly reduce biomechanical stress, while non-motorised devices showed limited effectiveness.

We compared this work design with one that ensured critical information was more readily available to all team members (high information integration). We used the Event Analysis of Systemic Teamwork (EAST) method to analyse task, information, and social networks for novice teams operating within a simulated submarine control room under low versus high information integration. Integration impacted team member centrality (importance relative to other operators) and the nature of information shared. Team members with greater centrality reported higher workload. Higher integration across consoles altered how team members interacted and their relative status, the information shared, and how workload was distributed. However, overall network structures remained intact.","PeriodicalId":50503,"journal":{"name":"Ergonomics","volume":" ","pages":"513-537"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141629226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
