Track: Human Factors and Ergonomics

Abstract

Background: Work-related musculoskeletal disorders in industrial workers are the leading cause of morbidity in employees leading to detrimental influence on the company's overall productivity and profit.

Problem statement: Long working hours in unsuitable posture can result in musculoskeletal disorders. If not treated these can progress to chronic illnesses in employees ultimately decreasing work efficiency and admonishing company output. Static and dynamic postures can cause severe musculoskeletal disorders and can harm permanently if immediate action is not taken.

Procedure/ approach: Using a technique called Rapid Upper Limb Assessment (RULA), it is possible to correct an employee's posture to a level that is acceptable. It also helps in reducing the severity of the problem by improving the working posture of employees and enhancing the productivity of the company. Posture correction process in time consuming since the adaptability of the new posture differs from person to person because of their varied anthropometric data.

Results: Reducing the severity of musculoskeletal disorders and optimizing working hours are possible when an employee's posture is improved. The workers who adopt the suggested posture have more task completion rate in the prescribed time. This was because the number of complaints connected to inappropriate posture during working hours was significantly lower.

Conclusions:  RULA utilizes a photographic memory technique that allows the expert to quickly improve an employee's posture without the need for expensive equipment, allowing for increased productivity during working hours. The need of ergonomic intervention for worker safety and willingness to adapt suggested posture when needed with immediate effect.
