ERGOQUEST ERGONOMIC GLOSSARY
For definitions to common ergonomic terms, see the Glossary below. It mainly covers terms about ergonomic positions and ergonomic workstation parts. If there is a term you think should be added to the Glossary, please let us know.
Monitor arms provide an adjustable arm attached to a platform on which you place your monitor so that the monitor height and distance can be easily adjusted.
Mechanisms that can adjust the height and position of a Keyboard Tray to an ergonomic height and location for the user. Superior models allow for features such as storability (when the tray is not in use), adjustable tilt (to provide a negative inclination to the tray), and extraordinary height range (for users desiring a sit stand solution).
A non-optimal posture for doing a task. How awkward a posture has to be to be problematic depends on
- How long the posture has to be held
- How frequently is must be used
- How much force is required while in the awkward posture
- Other things that have to be done at the same time
- Physical constraints (in tight places)
- Etc.
Common workstation accessories used to improve viewability and accessibility to reference materials (books, binders, file folders, etc.) while working on a computer (or alternate documents). Typically this type of accessory provides the ability to improve the physical location and angle of the material.
A height adjustment mechanism that uses internal springs or counterweights to offset the weight of a surface or component, allowing it to be raised or lowered smoothly with minimal effort and without the need for motors or locking knobs. This enables quick, precise positioning and easy re-adjustment during use.
An evaluation of a task or workstation to identify risk factors and improvement opportunities.
The word translates to “the science of work.” This is the practice of fitting the job to the worker and not the worker to the job in order to reduce the risk of work place injury. It accomplished by adapting the work environment, tools, equipment and job practices.
A systematic process for anticipating, identifying, analyzing and controlling ergonomic risk factors. The program may include observation, assessment, design and intervention, management and training.
A simple raised platform which provides a place for the feet to rest on while performing tasks. Superior models provide features such as height adjustability, angle adjustability, foot massage bumps, calf massagers, radiant heat and even the ability to be easily moved up and down or repositioned on the floor with just the feet.
A premium ergonomic recliner designed to support the body in a zero-gravity or near–zero-gravity position. The Perfect Chair evenly distributes body weight, reduces pressure on the spine, and promotes a neutral posture, making it suitable for extended sitting, relaxation, or work when paired with an ergonomic workstation.
A small work surface which can be affixed to a keyboard arm to provide an area to use the keyboard and mouse.
Short, frequent breaks that reduce fatigue and support recovery during the workday.
Injuries affecting muscles, joints, tendons, or nerves, often caused by work-related strain.
A body position where joints are naturally aligned to reduce stress and fatigue.
A type of ergonomic desk designed to let someone work while lying down or in a reclined position — useful for people with limited mobility or who need to work in bed.
A body position in which a person lies flat on their stomach, facing downward, with the chest and abdomen against the supporting surface.
An adjustment or modification (such as a custom workstation) that helps an individual with pain, disability, or limitations work comfortably and effectively — often used in employment or rehabilitation contexts.
Workplace conditions that increase the chance of discomfort or injury.
A body position where a person lies flat on their back, facing upward. The head, shoulders, back, and legs are fully supported, with little to no elevation of the upper body.
A body position in which a person lies on their back with the feet elevated higher than the head. This tilt shifts the body downward toward the head.
A focused review of desk, chair, equipment, and layout to improve comfort and safety.
An adjustable chair that places the user in a zero gravity or near-zero gravity posture. These may have motorized controls for backrest, seat, legrest, and headrest angles to support long-duration work or reduce pain.
A body posture where your feet are elevated above your heart and your back reclines at about 120–130°, originally developed by NASA. This position evenly distributes body weight, reducing stress on the spine and supporting a neutral posture to relieve pressure and improve comfort.
A customized ergonomic workstation designed to support multiple work positions — including reclined and zero gravity — so users can work comfortably without strain. These often support monitors, keyboards, and input devices while minimizing reaching and effort.
