This study investigates the prevalence, physical complaints, and impacts of heavy backpack use among junior high school students, with a focus on understanding how the weight and design of backpacks affect students' physical well-being and academic efficiency. The study was underpinned by the ergonomic theory. Using a descriptive survey design,…

Mismatches between children's anthropometric measures and classroom furniture dimensions can cause musculoskeletal disorders and affect performance in classroom activities. The aim of this study was to survey the anthropometric measures of primary school children in Akure South Local Government and to evaluate the level of match/mismatch between…

Musculoskeletal disorders (MSDs) related to occupational work or termed as WMSDs are the most common health issues that are experienced by many workers.

Background: Considering the amount of time children spend sitting in school, concerns about the consequences of an improper sitting position have been raised.Purpose: Evaluate the outcome of an occupational therapy intervention implemented to reduce child-furniture incompatibility.Methods: Repeated-measures design utilizing a within-subject…

The need for adjustability in school furniture, in order to accommodate the variation in anthropometric measures of different genders, cultures and ages is becoming increasingly important. Four chair-table combinations, different in dimensions, with adjustable chair seating heights and table heights were designed, manufactured and distributed to…

We aimed to evaluate the influence of different types of wheelchair seats on paraplegic individuals' postural control using a maximum anterior reaching test. Balance evaluations during 50, 75, and 90% of each individual's maximum reach in the forward direction using two different cushions on seat (one foam and one gel) and a no-cushion condition…

Educational ergonomics focuses on the interaction between educational performance and educational design. By improving the design or pointing out the possible problems, educational ergonomics can be utilized to have positive impacts on the student performance and thus on education process. Laptops and tablet computers are becoming widely used by…

This study evaluated the effectiveness of an automated observation and feedback system in improving safe sitting postures. Participants were four office workers. The dependent variables were the percentages of time participants spent in five safe body positions during experimental sessions. We used a multiple-baseline design counterbalanced across…

Improving employees' posture may decrease the risk of musculoskeletal disorders. The current paper is a systematic replication and extension of Sigurdsson and Austin (2008), who found that an intervention consisting of information, real-time feedback, and self-monitoring improved participant posture at mock workstations. In the current study,…
