Productivity and Physical Load Evaluation

Drywall-hanging laborers, especially during ceiling installation, are at high risk for musculoskeletal injuries, particularly those affecting the lower back and shoulders, due to exposure to frequent manual handling of heavy and bulky loads above shoulder height. Despite the potential for reducing the risk of injury and task-completion time, there are no available studies that investigate the impact of ceiling drywall-hanging assistive tools on total task-completion time and parameters of physical and physiological strain. To solve this problem, we propose to study and compare ceiling drywall installation methods with and without the use of the assistive tools. The long-term goal of this project is to implement a drywall ceiling installation method that incorporates the use of assistive tools, significantly reduces task-completion time, and reduces physical load at the shoulders, neck, and lower back. Our objective is to compare ceiling drywall installation methods with and without the use of the assistive tools, supported by a preliminary study on the efficacy and effectiveness of assistive tools during ceiling drywall installation which did not include the physical load measures. Reducing physical load at the shoulders, neck, and lower back will eventually reduce musculoskeletal injury risk and illness related to ceiling drywall installation, while simultaneously maintaining the productivity rate. Results from this project will determine the need for a large-scale intervention for efficacy testing of the selected method.
