RESUMO

OBJECTIVES: To analyze the association between occupational ergonomic risk, personal characteristics, and working conditions with the biomechanical properties of stiffness and muscular tone in the paravertebral muscles of electric pallet jack and forklift operators in the industrial sector. METHODS: A total of 75 industrial sector machine operators were evaluated in 2021. Personal characteristics and working conditions were assessed through a questionnaire. Ergonomic risk was assessed using the Rapid Entire Body Assessment (REBA) method, and biomechanical properties of stiffness and muscular tone were obtained using the Myoton Pro device. Stiffness in paravertebral muscles was compared based on the operated machine and observed ergonomic risk. A multilevel linear regression model was employed to quantify the relationship, with mean differences and 95% CI calculated. RESULTS: Very high ergonomic risk was found in 75% of the electric pallet truck drivers. In this group with the highest ergonomic risk, an association between biomechanical properties and older workers was observed. Additionally, among electric pallet truck drivers, stiffness (mean difference 335.9 N/m, 95% CI: 46.4 (3.4 to 110.0), P < 0.05) and paravertebral muscle tone (mean difference 17.5 Hz, 95% CI: 1.4 (0.1 to 3.4), P < 0.05) showed statistically significant differences in the very high ergonomic risk category compared to the high-risk category. No significant differences were observed in any of the analyzed variables among forklift drivers. CONCLUSIONS: Workers operating electric pallet trucks with very high ergonomic risk according to the REBA method and aged over 40 yr are associated with increased muscle stiffness and tone.

RESUMO

This study aimed to analyze the scientific evidence available in the literature addressing the relationship between mental fatigue and burnout associated with teleworking during the COVID-19 pandemic through an integrative review. This review searched the following databases: PubMed, Scopus, Taylor & Francis, Embase, ScienceDirect, and SciELO using the DeCS and MeSH health sciences descriptors. The included articles were published between March and December 2021, during the pandemic. Of a total of 224 results, 215 articles were excluded and 9 were considered for the preparation of this integrative review. Mental fatigue was related to technostress, somatic symptoms such as anxiety and insomnia (p < 0.05), and loss of motivation (p < 0.05). Burnout was positively associated with work overload, high interdependence, and lower role clarity. The presence of a stressful factor and a protective factor was evidenced in burnout: intrusive leadership and workaholism, respectively. Greater exhaustion was observed in workers belonging to generation X (41 to 55 years old). Mental fatigue is related to exhaustion in the productive, physical, and psychological dimensions of individuals. Addiction to work has moderated this phenomenon, however, it is urgent to limit and optimize work hours as well as promote disconnection and rest among workers within the framework of a healthy work policy.

Este estudo pretendeu analisar as evidências científicas disponíveis na literatura sobre a relação entre fadiga mental e esgotamento associados ao teletrabalho em tempos de pandemia de covid-19 mediante uma revisão integrativa. Esta revisão incluiu a pesquisa nos seguintes bancos de dados: PubMed, Scopus, Taylor & Francis, Embase, Science Direct e SciELO. Usando os descritores DeCs e MeSH de ciências da saúde, os artigos incluídos foram datados entre março e dezembro de 2021, durante a pandemia. De um total de 224 resultados, 215 artigos foram excluídos, e 9 foram considerados para a elaboração desta revisão integrativa. A fadiga mental foi relacionada ao tecnoestresse, à presença de sintomas somáticos, como ansiedade e insônia (p < 0,05) e à perda de motivação (p < 0,05). O esgotamento foi positivamente associada à sobrecarga, alta interdependência e falta de clareza quanto à função do trabalhador. Evidenciou-se a presença de um fator estressante e de um fator protetor em relação ao esgotamento, como a liderança intrusiva e o vício no trabalho, respectivamente. Observou-se maior exaustão nos trabalhadores da geração X (41 a 55 anos). Concluiu-se que a fadiga mental está relacionada à exaustão nas dimensões produtiva, física e psicológica dos sujeitos. A dependência do trabalho moderou esse fenômeno, porém, é urgente limitar e otimizar as horas de trabalho, bem como promover a desconexão e o descanso dos trabalhadores no âmbito de uma política de trabalho saudável.

RESUMO

Introduction: Within the occupational field, changes in the characteristics of work have revealed risks associated with static, repetitive work and litle physical activity, which together with individual health conditions of workers can trigger diseases and musculoskeletal disorders. Objectives: To obtain a preliminary characterization of workers in an industrial area, including their health and working conditions. Methods: This is a cross-sectional study with a quantitative approach, developed with 69 men who worked in the industrial area of Viña del Mar, Chile. A clinical and occupational evaluation was carried out with the application of the International Physical Activity Questionnaire as well as the Standardized Nordic Questionnaire. Results: The following risk factors were identified: 53.6% of the workers were smokers, 92.8% presented low levels of physical activity, and 70.3% reported feeling pain in body segments that were physically required during their work tasks. Among all workers, 63% were overweight according to their body mass index and 62% presented high systolic pressure. Pain was mostly detected in the spine, and it was slightly associated with forklif operation by older workers (t-test p < 0.05). Conclusions: Workers were in the presence of cardiovascular and occupational risks. It is necessary to promote timely education and training on health conditions and to evaluate risks associated with machinery operation in order to prevent work-related pain.

Abstract Introduction: A current trend in higher education is to merge subjects together to create one integrated or joint subject. However, an important effect of this integration has been reduced student performance and an increase in subject failures. A possible way to combat this issue may be through a favorable relationship that has been described between the application of process evaluations as teaching and learning instruments in health sciences, especially for the subjects that have a large volume of content. The objective of this study was to assess the effect that this evaluation may have on students' performance in the integrated subject of anatomy and physiology in Health Sciences. Materials and methods: This was an experimental study consisting of 144 students from the School of Health Sciences who were studying the subject of Structure and Function and were distributed amongst two groups: control and experimental. A methodological intervention was designed and implemented to assess its effect on academic performance. Results: The intervention of this process in the experimental control group showed an improvement in students' performance compared to that of the control group both in the average and in the partial evaluations of each unit (t-test < 0.05). In the experimental group, there was an increase in performance between 59% and 83% of the total number of students. Additionally, the progressive improvement modified the condition of disapproval to that of approval in 27% of the students after the intervention, Anova p < 0.05. Conclusion: The incorporation of process evaluations seems to be a favorable tool to decompress subjects taught in schools, to apply what students have initially learned, to follow up on the study methodologies, and improve overall student performance.

RESUMO

Introducción: Las dificultades presentes en la educación en ciencias de la salud son experimentadas por docentes y estudiantes en las asignaturas disciplinares. Los profesores requieren entregar y evaluar gran volumen de contenidos y los alumnos deben asimilar estos rápidamente para obtener un adecuado rendimiento. Objetivo: Evaluar la efectividad de la creación de mapas conceptuales sobre el rendimiento, en la asignatura Razonamiento Clínico de la carrera de kinesiología de una universidad privada de la V región, Chile. Métodos: Estudio cuasi experimental, en el que participaron dos grupos: control y experimental. En el grupo experimental se aplicó la intervención con la incorporación de la herramienta de creación de mapas conceptuales en dos unidades temáticas. Se evaluó el rendimiento pre- y posintervención. La población de estudio estuvo constituida por dos grupos de estudiantes de Kinesiología (n = 55), que cursaron la asignatura Razonamiento Clínico del séptimo semestre, correspondiente al primer semestre de 2017 de la malla curricular en la carrera de kinesiología, en una universidad privada de la ciudad de la V región, Chile. Resultados: El rendimiento pre- y posintervención indicó una diferencia significativa en las calificaciones correspondientes a las unidades II y III en el grupo experimental (t-test pareado p < 0,0001). Al comparar el desempeño entre ambos grupos: control y experimental, este último obtuvo un promedio de notas significativamente superior al grupo control en las unidades II y III (t-test, p < 0,0001). La unidad I no presentó diferencias notables entre el grupo control con respecto al experimental (ANOVA/Bonferroni post hoc test, p > 0,05). Conclusiones: La estrategia de crear mapas conceptuales incrementa el rendimiento en la asignatura Razonamiento Crítico para abordar problemas clínicos. La creación de mapas conceptuales favorece el aprendizaje y permite identificar habilidades que denotan mayor dificultad en los estudiantes. Se propone la incorporación de estos mapas en formación sistemática como herramienta de enseñanza y evaluación(AU)

Introduction: The difficulties present in health sciences education are experienced by teachers and students in disciplinary subjects. Teachers need to deliver and evaluate large volumes of content and students must assimilate these quickly in order to obtain adequate performance. Objective: To evaluate the effectiveness of creating conceptual maps on performance, in the subject Clinical Reasoning of the Kinesiology major of a private university of the V Region, Chile. Methods: Quasiexperimental study with the participation of two groups, a control group and an experimental group. In the experimental group, the intervention was applied with the incorporation of the tool for creating conceptual maps in two thematic units. Pre- and post-intervention performance was evaluated. The study population consisted of two groups of students of Kinesiology (n=55), who attended the subject Clinical Reasoning of the seventh semester, corresponding to the first semester of 2017, of the curriculum in the Kinesiology major at a private university in the city of the V region, Chile. Results: The pre- and post-intervention performance indicated a significant difference in the qualifications corresponding to units II and III in the experimental group (paired t-test p<0.0001). When comparing the performance between both groups, control and experimental, the latter obtained an average of significantly higher scores than the control group in units II and III (t-test, p < 0.0001). Unit I did not show notable differences between the control group and the experimental group (ANOVA/Bonferroni post hoc test, p > 0.05). Conclusions: The strategy of creating conceptual maps increases the performance in the subject Critical Reasoning, for the addressing of clinical problems. The creation of conceptual maps favors learning and allows the identification of skills that denote greater difficulty in students. The incorporation of these maps in systematic training is proposed as a teaching and evaluation tool(AU)
