The organization of space and working conditions is very important in terms of its effectiveness. Each professional work determines activities that support occupational safety and health at the workplace. Lack of proper working conditions but also the time of exposure to dangerous, burdensome or harmful factors has an impact on the effectiveness of the work performed. Lack of balance between work and leisure in turn results in a decrease in work efficiency. The scientific and didactic work of academic teachers is related to the occurrence of diversified occupational hazards with particular emphasis on those that are the cause of musculoskeletal disorders. In this elaboration, the research, analysis and evaluation of the work effectiveness of academic teachers have been carried out. A questionnaire and a direct interview have been used as a research method. In addition, the pain intensity in individual parts of the body has been assessed in the last 12 months depending on the age of research and teaching staff using the NMQ questionnaire (Nordic Musculoskeletal Questionnaire). For the purposes of the study, the survey was supplemented with the VAS (Visual Analogue Scale) scale to assess the severity of pain. The purpose of the paper is to evaluate the frequency and severity of musculoskeletal pain in academic teachers with regard to the effectiveness of their work.

Objectives. Musculoskeletal disorders (MSDs) are prevalent among airline baggage handlers due to manual materials handling. In this study, the Nordic musculoskeletal questionnaire (NMQ), the revised National Institute for Occupational Safety and Health (NIOSH) lifting equation, and the University of Michigan 3D Static Strength Prediction Program™ (3DSSPP) were used to analyze MSDs among baggage handlers. Methods. The NMQ was filled out by 209 baggage handlers and 46 arbitrarily selected baggage handlers were evaluated using the NIOSH method and 3DSSPP. Results. The obtained results showed that the most common MSDs occurred in the lower back region. The next risky regions included knees, neck, and upper back, respectively. The NIOSH results confirmed that the subjects lifted loads heavier than the permitted limit and their lifting postures were inappropriate. The results of the 3DSSPP also indicated that compression forces exceeded the NIOSH limit in these awkward postures. Conclusions. Relying on this study, holding compulsory ergonomic lifting training courses could be proposed for workers and regulations adjusting an upper limit for maximum baggage weight must be also enacted in order to improve occupational health and prevent the prevalence of increasing MSDs.

This 8-week study evaluates the effects of customized foot orthoses on work-related musculoskeletal disorders (WMSDs) of metal industry workers. These WMSDs were evaluated applying the Nordic musculoskeletal questionnaire (NMQ) at three different times (start, 4th week and 8th week) and additional questions were also formulated to obtain information about adaptation, fatigue, comfort and possible improvements. According to the NMQ results, statistical significance was found in the improvements after 4 weeks (p < 0.05 in two areas, p < 0.01 in three areas, p < 0.001 in two areas and no significance in the other two) and after 8 weeks (p < 0.01 in three areas, p < 0.001 in four areas and no significance in the other two). The additional questions indicated fatigue reduction (both in general and in lower extremity), comfort level increase (after the adaptation period) and good acceptance, according to workers’ answers, suggesting customized orthoses can be effective in reducing and preventing WMSDs in several body regions.
