Mar 5, 2024 · Ergonomics is the science of designing and arranging environments, products, and systems to fit the people who use them. Learn about the different types of ergonomics, such as physical, cognitive, organizational, and environmental, and see real-world examples of ergonomic solutions.
- Poor Sitting Posture. Poor sitting posture may feel innocuous, even satisfying. Whether you’re slouching or leaning forward at your desk, there is a sense of relief as your core and lower back muscles relax.
- Awkward Postures. Closely related to the first item above is awkward postures in general. These are unnatural body positions that you assume when bending, twisting, and overreaching.
- Prolonged Stationary Position. One of the biggest silent killers at the workplace (and home) is a sedentary lifestyle. This is when we stay in the same position every day for many hours on end.
- Frequent, Repetitive Movements. Performing repetitive motions repeatedly, however small, can cause microtrauma to the surrounding tendons and tissues, leading to inflammation and eventually dysfunction.
Strength and dexterity. Visual and auditory abilities. Mental processing and decision-making skills. On the other hand, understanding a user’s limitations is equally important. Some examples include: Fatigue and stress. Inadequate workspace. Lack of adjustable equipment. Information overload or insufficient training.

Neutral postures are postures where the body is aligned and balanced while either sitting or standing, placing minimal stress on the body and keeping joints aligned. Neutral postures minimize the stress applied to muscles, tendons, nerves and bones and allows for maximum control and force production. The opposite of a neutral posture is an “awkward...
This principle is very similar to maintaining a neutral posture, but is worth expounding upon here. The power zone for lifting is close to the body, between mi-thigh and mid-chest height. This zone is where the arms and back can lift the most with the least amount of effort. This can also be called the “hand shake zone” or “comfort zone.” The princ...
The musculoskeletal system is often referred to as the human body’s movement system, and it is designed to move. Working for long periods of time in a static position will cause your body to fatigue. This is what is known as static load. For example: 1. Raise your hands over your head for the next 30 minutes 2. Remain standing in the same position ...
Excessive force is one of the primary ergonomic risk factors. Many work tasks require high force loads on the human body. Muscle effort increases in response to high force requirements which increases fatigue and risk of an MSD. There are numerous conditions that affect force, but the idea is to recognize when a job or task requires excessive force...
Repetitive motion is another one of the primary ergonomic risk factors. Many work tasks and cycles are repetitive in nature, and are frequently controlled by hourly or daily production targets and work processes. High task repetition, when combined with other risks factors such high force and/or awkward postures, can contribute to the formation of ...
According to OSHA, contact stress results from continuous contact or rubbing between hard or sharp objects/surfaces and sensitive body tissue, such as soft tissue of the fingers, palms, thighs and feet. This contact creates localized pressure for a small area of the body, which can inhibit blood, nerve function, or movement of tendons and muscles. ...
Multiple studies have shown that regular and frequent exposure to vibration can lead to permanent adverse health effects, which are most likely to occur when contact with a vibrating tool or work process is a regular and significant part of a person’s job. Hand-arm vibration can cause a range of conditions collectively known as hand-arm vibration s...
Poor lighting is a common problem in the workplace that can affect a worker’s comfort level and performance. Too much or too little light makes work difficult – just imagine trying to do your job without sight! Dimly lit work areas and glare can cause eye fatigue and headaches and improperly lit areas put workers at greater risk for all types of in...
Workplace ergonomicsdoesn’t have to be as difficult or complicated as brain surgery. The ergonomic principles included in this article are mostly common sense – it’s the practical, day-to-day application of these principles that is challenging for many companies. By developing your “ergo eyes” and adhering to these fundamental ergonomic principles,...
Learn eight ergonomic principles to prevent musculoskeletal disorders and improve work efficiency. See examples of neutral and awkward postures, power zones, stretching, force reduction, motion minimization, contact stress, vibration and lighting.
Mar 25, 2024 · Ergonomics is a discipline that studies the interactions between human activity and the components of this activity to develop systems that allow people to work in conditions of optimal efficiency, safety and comfort. Learn about the three dimensions of ergonomics (physical, cognitive and organizational) and some examples of ergonomics in different sectors (transport, internet, sustainable development).
