OBJECTIVE The unavailability of anthropometric data especially in developing countries has remained a limiting factor towards the design of learning facilities with sufficient ergonomic consideration. Attempts to use anthropometric data from developed countries have led to provision of school facilities unfit for the users. The purpose of this paper is to(More)
OBJECTIVE The aim of this study was to investigate the work-related musculoskeletal disorders (WMSDs) among workers in wall plastering jobs within the construction industry. PARTICIPANTS A total of 43 workers within three workplaces participated in the study. METHODS Subjects were interviewed using self-report charts. During the task duration,(More)
Back pain among school children using backpacks is still a problem and generating interest from academia. Most research has been limited in scope. While some researchers carried out experimental investigations using biomechanical and physiological principles, others based their research on psychosocial issues. The inability to recognize the complexity of(More)
The study analysed backpack-related back pain in school children by investigating the possibility of multiple interactions among causative factors, which may be responsible for the non-conclusive findings on the issue. Using data from 444 prepubescent schoolchildren, a mixed method design combining survey, observation and direct measurement strategies was(More)

Introduction: The provision of ergonomically designed school furniture, based on the anthropometric dimensions of the children, is essential for comfort and prevention of musculoskeletal disorder that may arise from the use of mismatched furniture. This is because school furniture and backpack has been identified as a major risk factor for back pain and(More)
BACKGROUND The complex and limited understanding of the interactions among multiple factors associated with back pain occurrence among schoolchildren might explain the current inconclusive and contradictory findings on the issue. The global increase in the prevalence of childhood overweight and obesity, which reportedly affects children's physical(More)
This paper describes the development of the Workplace Ergonomic Risk Assessment (WERA) for investigating the physical risk factor associated with work-related musculoskeletal disorders (WMSDs). The initial development of WERA tool involved the following procedures: (1) first stage, development of WERA prototype from literature review, (2) second stage,(More)
Lean Manufacturing (LM) is a business strategy that was developed in Japan. The main contribution of lean manufacturing is the identification and elimination of waste. Companies apply LM to sustain their competitiveness over their competitors by improving the manufacturing system’s productivity and quality enhancement of the product. The goal of this paper(More)
The occurrence of back pain and its associated risk factors were investigated among school children in Nigeria with the aim of developing a robust predictive back pain model. Data were obtained using a selfreported questionnaire which was distributed to 255 schoolchildren, aged 8 to 13 years. After data screening, SPSS was used to analyze responses from 212(More)
