“…CTDs are one of the skeletal muscle disorders associated with repetitive activities and non-ergonomic work postures. CTDs are injuries that develop over time, which can take weeks, months, or even years [5]. Work posture is a risk factor that most need attention.…”

Background: The interaction of workers and work tools does not always have a good impact; the mismatch of worker anthropometry and work tools impacts work-related diseases. Jobs with repetitive motions, manual lifting, and awkward postures cause complaints of CTDs. These complaints impact decreased productivity and, in the long run, cause permanent disability. This study aims to determine the risk factors for CTDs complaints. Material and methods: Analytical observational research with a quantitative approach and a cross-sectional design. The population in this study is production workers at an Indonesian spinning and dyeing factory company. The sampling technique used is Total Sampling. The dependent variable is Complaints of CTDs, with the independent variables namely work posture, gender, age, BMI, and years of service. The research instruments used were questionnaires and REBA. Univariable analysis to determine the frequency distribution and bivariable analysis with the chi-square test. Result: Work posture is at risk of experiencing CTDs complaints as much as 90.9%, female sex as much as 71.2%, old age 87.9%, BMI not at risk 56.1%, years of service ≥4 years is 95.5%, and there are very high CTDs complaints 66.7%. There is a relationship between work posture (p value=0.001) and years of service (p value=0.003) with CTD complaints. There was no relationship between gender (p value=0.393), age (p value=0.960), and BMI 0.429) with complaints of CTDs. Conclusion: Most workers experience complaints of CTDs. The risk factors for CTDs revealed in this study are work posture and length of service.

“…CTDs are thought to be caused by high power exertion, repetitive motion, and uncomfortable wrist and hand postures ( Birkbeck and Beer, 1975 ; Silverstein et al, 1987 ; Asadi et al, 2020 ). We currently do not know the magnitudes of these factors or how they interact ( Cázares-Manríquez et al, 2021 ; Short et al, 2022 ). Because tasks can be planned with more precise positioning in mind to reduce the incidence of CTDs, it is crucial to understand the link between grip force and wrist joint position sense.…”

BackgroundThe purpose of this study was to investigate how grip force affects wrist joint position sense.MethodsTwenty-two healthy participants (11 men and 11 women) underwent an ipsilateral wrist joint reposition test at 2 distinct grip forces [0 and 15% of maximal voluntary isometric contraction (MVIC)] and 6 different wrist positions (pronation 24°, supination 24°, radial deviation 16°, ulnar deviation 16°, extension 32°, and flexion 32°).ResultsThe findings demonstrated significantly elevated absolute error values at 15% MVIC (3.8 ± 0.3°) than at 0% MVIC grip force [3.1 ± 0.2°, t(20) = 2.303, P = 0.032].ConclusionThese findings demonstrated that there was significantly worse proprioceptive accuracy at 15% MVIC than at 0% MVIC grip force. These results may contribute to a better comprehension of the mechanisms underlying wrist joint injuries, the development of preventative measures to lower the risk of injuries, and the best possible design of engineering or rehabilitation devices.

“…Previous reports of the application of IRT indicate that it served as an aid in diagnosing carpal tunnel syndrome (CTS) in 44 samples, differentiating healthy hands from those with pathologies [ 16 ]. A study was carried out on workers in a manufacturing company in which 75% of the people who performed a highly repetitive movement were diagnosed with some injury through IRT [ 17 ]. Temperature asymmetry is an aspect to consider in determining an abnormal pathology in chronic diseases [ 18 , 19 ].…”

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.
