Study of postures in sugarcane cutters in the Pontal of Paranapanema-SP, Brazil

The expansion of sugarcane monoculture in Brazil in the last decades has pointed out to the necessity of considering the question of sugarcane cutters occupational health. In this work we present a cross-sectional study aiming to examine the occupational posture of a group of sugarcane cutters, which work in a cane field located in the region of Pontal do Paranapanema-SP, Brazil. The study was made using the Ergonomic Analysis of Work - EAW methodology and the postural analysis method by Win-OWAS. Through the obtained records of postures, it was observed that during a workday the sugarcane cutters remain standing erect on two legs or in one leg 66% of the time and that their trunk remain tilted and in rotation, according to 63% of the positions categorized. It was also observed that the sugarcane cutter trunk performs repetitive and boundless movements during his routine of work, which can expose this individual to additional wear of their musculoskeletal functions. The activities in which the individual engages have favorable or adverse influence on his posture. The repetitive movements involved in specialized occupations are equivalent to repeated exercises, thus may be responsible for the excessive development of certain muscle groups. The study suggests that the postures adopted by sugarcane cutters can overload their musculoskeletal system and predispose the cutters to work-related musculoskeletal diseases.

Behavior analysis of electromyographic activity of the masseter muscle in sleep bruxers

The effects of occlusal splint on the electric activity of masseter were studied in 15 women who presented sleep bruxism using surface electromyography. Sleep bruxism was defined by its clinical characteristics. The signal acquisition was done during mandible occlusion without clenching and maximum voluntary contraction in two situations. The first was after a workday without using the occlusal splint; and the second, after a sleeping night using occlusal splints. Evaluating masseter muscles during mandible occlusion without clenching, it could be observed that lower values were noticed after splint wearing in both sides. The same results were verified in maximum voluntary contraction (MVC). These results confirmed that the use of occlusal splints reduced the electromyographic activity of the right and left masseters, showing its myorelaxing effect. © 2009 Elsevier Ltd.

Electromyographic analysis of masseter and anterior temporalis muscle in sleep bruxers after occlusal splint wearing

Bruxism is widely defined as an anxiety response to environmental stress. Occlusal splints are frequently used in sleep bruxism, to protect teeth from damage resulting from the contraction force of mandibular muscles, or to reduce the orofacial pain by relaxing masticatory muscles. Surface electromyography (EMG) of the right and left masseter and temporalis muscles was performed in 15 women presenting sleep bruxism and temporomandibular disorders related to occupational stress, after nocturnal use of the occlusal splint. The EMG signals were recorded twice per patient: After a work shift (pre-splint) and after a night of sleep with the occlusal splint (post-splint) before a new workday. The parametric t-paired test was used to compare differences of the RMS amplitude between pre and post-splint records, for resting and maximal clenching effort. The level of significance for each comparison was set to p < 0.05. The results of the study supports the premise that the use of occlusal splint reduces EMG activity in the masseter and anterior temporalis muscles, in patients who presented with sleep bruxism related to occupational stress. © 2011 Elsevier Ltd.

Efeito de um programa de ginástica laboral na saúde, estados de ânimo e estresse diário do trabalhador

The practice of regular physical activity has been widely recommended in the literature, indicating an improvement of the physical and psychological activities promoted through the routine of workers. In this sense, physical activity has become of great importance in the workplace, for the prevention of injuries caused by normalizing bodily functions and staff providing relaxation and socialization, basic elements of daily life a worker. This study aimed to analyze the effects of a active break program in the routine of workers in their mood and stress, even checking the influence of physical activity on quality of life of participants. We selected 15 individuals of both genders, the restaurant staff University, UNESP - Rio Claro-SP. The activities lasted four months, two times a week, at the beginning of the workday, for 15 minutes, followed by stretching and playful activity. The evaluations were answered a week before the execution of the program and lists of mood states have been answered before and after the activity, and the end of working hours and also at the beginning and end of the days when there were no interventions. After analyzing the results, we concluded that the participants have a good index of perception of quality of life with total score of 76.6 for mental and physical health and that all assets are considered in accordance with the recommendations of 150 minutes of physical activity per week. More than 50% of them have symptoms of stress found mostly in the resistance stage, and no changes were found in the mood states when practicing active break or not. We conclude that the changing of moods can be associated with the fact that workers are already active, another reason may be due to low number of participants in the study, given other studies show that there is a change and that active break interferes positively in mood states of individuals

O trabalho docente na rede pública do estado de São Paulo: apontamentos iniciais para a discussão da jornada de trabalho

The changes in the world of work that, in turn, directly affect the teaching work, have expanded the processes of precariousness and intensification, contributing for deteriorating conditions which teachers use to labor. Considering that the time designated for teaching activities is an important part of work conditions, we look for, in this article, to analyze the work shift of teachers in São Paulo state educational public system. Regarding that teachers are a very heterogeneous group, we have chosen to discuss the workday those professionals who dedicate themselves in the last years of elementary and high school. Through a literature review and a research about the legislation related to the topic, in Brazil and São Paulo state, we have highlighted that the teachers’ work shifts should include not only the time for classroom activities, but also for other extra activities. Moreover, we emphasize that the state of São Paulo government has promoted, since 2012, a reformulation of the teachers’ work shift that has not properly include the appropriate length of time for extra educational activities, contrasting the parameters founded in the national legislation. Besides the legal non-compliance, that fact has accentuated the process of intensification of teaching work, contributing for the embrittlement of the collective activities.

A influência da escola de tempo integral sobre a qualidade de vida infantil

This study aims to evaluate the quality of life of students aged 7 to 12 years in two municipal schools in the municipality of Minas Gerais. One offers full-time care to their students with extracurricular activities and other school offers only the normal. We used the questionnaire AUQEI, Autoquestionnaire Qualité de Vie Enfant Image. The questionnaire was administered to 232 children. Through this study, we observed that the proportion of children with a good Quality of Life was higher in school full time (81%), compared to the normal school hours (58%). Therefore, it is concluded that the school offers an extended workday, is set in an area rich able to develop the maximum potential of children and their personal skills, which will reflect positively on their quality of life.
