Abstract
The construction industry is known for its task-related risks and hazards contributing to occupational stress and musculoskeletal disorders (MSDs). The study sought to identify the impact of MSDs among concrete mixer operators and workers in the construction industry in the Central Region of Ghana. The population for the study was made up of 28 concrete mixer operators and 187 workers. Out of the 215 questionnaires administered, 206 questionnaires were returned which represented 95.8 % of the response rate. Descriptive statistics and Relative Importance Index (RII) were used for the data analysis. Findings show that most of the workers were young males and worked for a longer period a day. Force movement, repetition, awkward bending and fixed body postures were the major factors leading to the development of MSDs and contributed to frequent absenteeism and poor performance of workers. Further findings show that back pain, waist pain and shoulder pain were the major self-reported MSD complaints. Risk assessment should be conducted on all site hazards and ergonomic tools/equipment should be introduced to reduce the impact of MSDs on workers.
