In ergonomics, which class of motion pertains to the movement of fingers and wrist?

Class I
Class II
Class III
Class IV

The correct answer is: Class II

In the study of ergonomics, the classification of motions is often used to categorize the type of movements involved in various tasks, especially those related to a clinical environment. The movement of fingers and wrist is categorized as Class II motions. Class II motions specifically refer to fine motor skills that require dexterity, such as tasks that involve precise hand movements, gripping, and manipulation of various tools or instruments. This classification is critical as it relates to how healthcare professionals perform their duties efficiently and comfortably, thereby reducing the risk of injury or strain. Understanding which class pertains to specific movements helps in the design of workspaces and tools to fit human physical capabilities, promoting better ergonomics and overall health in the workplace.
