Ergonomics is defined as the study of people's efficiency in their working environment, with the goal of minimizing injuries from physical and psychological stresses while maximizing productivity. Some risk factors for musculoskeletal disorders include prolonged use of vibrating tools, static postures of the neck, back and shoulders, repetitive motions like scaling and polishing, and grasping small instruments or using excessive force for long periods.
