“…One of the findings of this research shows that both techniques are useful for assessing skin temperature and identifying rapid changes in skin temperature, because they can predict the presence of musculoskeletal disorders [ 11 , 51 ]. Previous studies have shown that acute injury causes an increase in permanent blood flow, which implies increased metabolic activity, as demonstrated in this study [ 52 ].…”

This article reports a thermal analysis of the wrists to analyze the behavior and recovery of skin temperature after 20 min when performing a highly repetitive movement, and two thermography methods (sensory and infrared) and research groups were compared. The tests were carried out with 44 participants who performed a repetitive task for 10 min and integrated into two groups, of which 22 were trained workers from a maquiladora company and were analyzed with sensory thermography, and the other 22 were in the laboratory with infrared thermography with undergraduate students. The study area is the left and right hand, specifically the wrists. The proposed hypothesis is that people with some musculoskeletal problems have a decrease in temperature when starting repetitive tasks and thermal asymmetries, which measurements were recorded at 0, 10, 15, and 20 min after the task was finished. Findings indicate that the temperatures in both wrists behave similarly. The workers reached higher temperatures, and the centigrade degrees of asymmetry difference were also higher. The variable with influence on the temperature was fractured in the arm. After thermally analyzing the temperature behavior between the wrists of both hands, it is concluded that there is an increase in temperature after finishing a repetitive task, and it does not stabilize after 20 min. Both thermography methods observed that the asymmetries are greater than 0.5 °C, detecting the possible pathology of carpal tunnel syndrome.

“…Para la evaluación de los impactos de las tareas repetitivas en los trabajadores se han desarrollado y aplicado técnicas y metodologías generales que incluyen factores ergonómicos para disminuir la probabilidad de las lesiones. Estas técnicas actúan de manera preventiva en las estaciones de trabajo, lo que mejora el desempeño de los trabajadores y la funcionalidad sus estaciones de trabajo (Ring & Ammer, 2012;Soares et al, 2020). Por otro lado, existe un conjunto de métodos comunes que evalúan la carga muscoesquelética y los riesgos de desarrollar lesiones muscoesqueléticas, los cuales determinan valores de entrada de la carga externa e interna en las distintas partes del cuerpo (Sousa et al, 2017).…”

El estudio analizó el comportamiento musculoesquelético de cinco operadores mientras realizaban una tarea repetitiva en una estación experimental, con el fin de prevenir accidentes y enfermedades laborales a corto, mediano y largo plazo. Se utilizó termografía infrarroja para monitorear las temperaturas y se enfocó en áreas específicas del brazo de los cinco trabajadores. A ritmo normal, se observó mayor actividad muscular en codo, antebrazo y hombro, y con menor impacto en mano y brazo. Al aumentar el ritmo, se intensificó la actividad en mano, hombro y codo, mientras que antebrazo y brazo mostraron menor actividad. Los resultados indican que la termografía es útil para identificar niveles de actividad muscular, lo que ayudaría a prevenir lesiones. Además, se observó que los operadores aumentaron su producción de ensamblaje de piezas de la siguiente manera: 1(+64), 2(+26), 3(+62), 4(+3) y 5(+52).

Temperature gradient changes on the surface of the skin or in the middle of the body are signs of a disease. The aim of this study is to develop quantitative models for the prediction of cumulative trauma disorders (CTDs) arising from highly repetitive activities, considering risk factors, such as age, gender, body mass index (BMI), blood pressure (BP), respiratory rate (RR), and heart rate, to prevent injuries in manufacturing factory operators. This research involved 19 individuals from the area of sanding and 14 individuals from the area of tolex in manufacturing factories who had their vital signs and somatometry taken, as well as thermal images of their hands in the dorsal and palmar areas; an evaluation by the OCRA method was also applied. Factors such as BP and heart rate were determined to significantly influence the injuries, but no strong association with BMI was found. Quadratic regression models were developed, the estimates of which were adequately adjusted to the variable (R2 and R2 adjusted > 0.70). When integrating the factors of the OCRA method to the generated models, a better fit was obtained (R2 and adjusted R2 > 0.80). In conclusion, the participants who present levels out of the normal range in at least one of the factors have high probabilities of developing injuries in their wrists.
