The Mismatch of Students Anthropometric Data with Ergonomic Designs of Learning Workstation is a Risk Factor for Musculoskeletal Disorders

Abstract: This study examined the relationship between anthropometric data of Nigerian Students in Higher Academic Institutions, the ergonomic design of classroom furniture and the risk of Musculoskeletal Disorders (MSDs). A total of one hundred and seventy five (175) students, aged between 17-34 years, in thirty one (31) randomly selected classrooms participated in the research. Students' anthropometric data were collated by measuring various body dimensions such as sitting elbow height, shoulder height, knee height, popliteal height, buttock popliteal length, and stature, using anthropometer, and measuring tape. Also, classroom furniture dimensions were measured with metal measuring tape, vernier caliper and goniometer. A survey was conducted using questionnaire
to identify the body areas of discomfort (MSDs) experienced by students. It was established that, there are three different types of furniture (A, B and C). This study revealed that there is a mismatch between available classroom furniture and students' anthropometric data, which is responsible for the musculoskeletal disorders complaints by the students. It is expected that the study will help decision makers and analysts in designing appropriate learning workstations using various students’ anthropometric data in order to avoid the risk of musculoskeletal disorders.
