“…Using anthropometric measurements in design improves students' comfort (8,30) and reduces musculoskeletal disorders (MSDs) (18,31), and consequently improves their performance (10,32). Furthermore, MSDs are defined as injuries in the muscular and nervous systems, including muscles, bones, joints, tendons and ligaments, nerves, and blood vessels, which can limit usual activities of students (33)(34)(35). Work-related MSDs are one of the consequences of awkward posture that can influence efficiency, performance, well-being, and quality of work (36).…”

Background: Proper designing of chairs based on ergonomics increases efficiency, promotes quality of education, leads to correct posture in students, and reduces risk of musculoskeletal disorders. Objectives: The aim of this study was to design and develop an ergonomic chair, based on anthropometric data of students in educational settings. Methods: Anthropometric parameters were obtained from a stratified-random sample of 207 students. The data were analyzed using the SPSS 20 software, and the results were extracted as mean, standard deviation, and percentiles. The chair was planned in the CATIA software and developed by a three-dimensional print. Results: In this study, an ergonomic chair was designed based on anthropometric data from students. The seat height, depth, and width of the chair were determined as 44 cm, 42 cm, and 42.15 cm, respectively. The height of the desk was adjustable in 19 to 29 cm, and the depth and length of the desk were considered as 51 cm and 65 cm. The width and height of the backrest were also 54 cm and 44 cm, and the backrest angle was adjustable in 95°to 105°. Conclusions: An ergonomic chair with adjustable parts was designed to achieve a well-match between anthropometric characteristics of students and the furniture. Such chair can reduce musculoskeletal disorders in students. Some ergonomic characteristics of this chair include adjustability of footrest, backrest, armrests, and desk. A chair with such characteristic can be used by many students with different body sizes.

“…Musculoskeletal disorders are defined as any damage to the muscular and nervous system including muscles, bones, ligaments, tendons, and blood vessels [9]. This disorders can affect the ability, efficiency and effectiveness, well-being, productivity, absence from work, quality of work, and performance of individuals [10,11], as well as leading to create restrictions on the normal activities of students [12,13].…”

Journal homepage: www.zums.ac.ir/jhehp Background: Since students spend a lot of time in classrooms and in steady state, many of them may experience signs of musculoskeletal disorders. The aim of this study was to determine the prevalence of musculoskeletal disorders and its related risk factors among students. Methods: This descriptive-analytical and cross-sectional study was conducted among 129 students of Qazvin University of Medical Sciences in 2016. In order to determine the prevalence of musculoskeletal disorders, Nordic questionnaire was used. The relationship between musculoskeletal disorders and risk factors was evaluated in SPSS20 software. Results: The highest incidence of musculoskeletal discomfort (80%) was observed in the waist area. The neck (38.3%) and shoulder (35%) were the most prevalent at the next levels. Marital status, age, weight, educational level, job, exercise and stress were identified as risk factors affecting the musculoskeletal disorders in the students. Conclusion: It is possible to reduce the prevalence of musculoskeletal disorders by the necessary trainings to declare the risk factors and their modifications to the students, considering appropriate time between the classes and the use of ergonomic equipment and furniture in the classes. With these actions also can prevent from stress and consequently can increase the concentration and learning power in this group.

“…Participants were included if they were 18 years old and above, using a VDU at work for more than 4 h a day (Lapointe et al 2013 ; Mirzaei et al 2014 ; Oha et al 2014 ; Poochada & Chaiklieng 2015 ), working more than 12 months in their current job or a similar occupation. The exposure for 4 h or more was considered to be sufficient exposure to the risk factors for MSD in similar studies of VDU users (Lapointe et al 2013 ; Mirzaei et al 2014 ; Oha et al 2014 ; Poochada & Chaiklieng 2015 ). Employees who had undergone surgery for MSD in the previous 2 years, or were undergoing mental health treatment, including but not limited to depression and anxiety were excluded.…”

Background The dramatic increase in visual display units (VDU) in the workplace over a 20-year period is linked to the increased prevalence of musculoskeletal disorders (MSDs). Objectives The objective of our study was to compare ergonomic risk factors and work-related psychosocial factors in VDU users with and without MSD. Methods Participants, with and without MSD, working with VDU for more than 4 h a day completed the Nordic Musculoskeletal Questionnaire and the Effort-Reward Imbalance Model and Over-commitment Questionnaire. The workstation of each participant was assessed for ergonomic risk factors using the Rapid Office Strain Assessment (ROSA). Results Sixty-eight VDU users with and 68 without MSDs participated. The workstation ergonomic risk factors as measured with the ROSA were similar for the two groups: 4.5 ± 1.0 for the MSD group and 4.3 ± 0.8 for the reference group ( p = 0.10). The work-related psychosocial factors, namely over-commitment, were higher in the MSD group (14.9 ± 3.1) than in the reference group (13.8 ± 3.4; p = 0.041). Conclusions As over-commitment is an indication of intrinsic factors and personal characteristics, the significant difference between the MSD group’s over-commitment score and that of the reference group suggests that interventions to empower individuals are needed. Clinical implications Physiotherapists should only adjust ergonomic workstation risk factors when established as contributory to MSD, and should be cognisant of work-related or individual psychosocial factors that may impact the patient with MSD. The use of ergonomic advice to patients with MSD should be performed with caution, taking all the work place risk factors for MSD into account.
