Ergo Wisdom 02: Minimizing Excessive Forces
Ergo Wisdom 02: Minimizing Excessive Forces
"Minimizing excessive forces" focuses on reducing the physical effort required to perform tasks. When people exert too much force, whether from lifting heavy objects, gripping tools too tightly, or applying unnecessary pressure, it can lead to muscle strain, fatigue, and even long-term injury. This principle encourages work environments and practices that reduce the physical demand on workers, ensuring that they can perform tasks comfortably without overexertion.Â
Below are practical guidelines and tools to help minimize excessive forces in the office environment
Below are practical guidelines and tools to help minimize excessive forces in the office environment
Chair Height AdjustmentsÂ
Chair Height AdjustmentsÂ
Adjusting the height of an office chair is essential for maintaining proper posture and comfort while sitting.Â
The correct chair height allows your feet to rest flat on the floor, with knees bent at a 90-degree angle or slightly more.Â
When the chair is properly adjusted, it helps prevent strain on the lower back, thighs, and legs. It also encourages a neutral spine position by ensuring that the thighs are parallel to the floor, reducing the risk of discomfort during long periods of sitting.Â
Many modern office chairs have gas-lift mechanisms that allow for easy adjustment, helping workers of varying body types find a comfortable sitting position.Â
Desk Height Adjustments
Desk Height Adjustments
Desk height is crucial for promoting a healthy posture while working.Â
An ergonomic desk should allow you to keep your arms at a 90-degree angle when typing, preventing strain on the wrists and shoulders.Â
The desk height should be set so that the forearms remain parallel to the ground, and the user’s wrists do not need to bend upwards or downwards while typing. It is also important that the desk is high enough to accommodate the user’s knees and thighs without obstruction, especially if they are using a chair with adjustable height.Â
Some modern desks are designed with height adjustability, including sit-stand desks, to offer flexibility and promote movement throughout the day.Â
Footrests and Support Cushions
Footrests and support cushions are important ergonomic accessories designed to alleviate discomfort and promote proper posture.Â
A footrest is used when the chair height is too high, causing the feet to dangle, which can lead to pressure on the legs and lower back.Â
Footrests provide a stable surface for the feet, encouraging a natural sitting posture by ensuring that the knees are at a 90-degree angle.Â
Keyboards and Mouse
Ergonomic keyboards and mouse are designed to reduce strain on the hands, wrists, and forearms.Â
Standard keyboards often force the user to bend their wrists in unnatural ways, leading to repetitive strain injuries like carpal tunnel syndrome.Â
Ergonomic keyboards are split into sections or have a slight curve to allow for a more neutral hand position, reducing wrist bending and tension.Â
Similarly, an ergonomic mouse is shaped to fit the natural curve of the hand, reducing the need for excessive gripping and preventing wrist strain.Â
Document Holders
Document holders are designed to help reduce neck and eye strain by keeping papers at eye level while working.Â
When documents are placed flat on the desk, you often have to bend their necks downward to read them, which can cause strain over time.Â
Document holders are adjustable and allow papers to be positioned at a comfortable height and angle, reducing the need to look down repeatedly.Â
By keeping documents closer to the monitor, you can also minimize the amount of head and eye movement between the two.Â
Wrist Supports
Wrist supports are accessories designed to provide cushioning and stability to the wrists while typing or using a mouse.
 They are commonly placed in front of a keyboard or mouse to help maintain a neutral wrist position, reducing the risk of strain and injury.Â
Without wrist support, extended periods of typing or mousing can lead to wrist discomfort, stiffness, and even repetitive strain injuries such as tendinitis.Â
For optimal ergonomics, wrist supports should be used with proper keyboard and mouse positioning to prevent bending or overextension of the wrists.Â
Lumbar Support Cushions
Lumbar support cushions are designed to provide additional support to the lower back, ensuring that the natural curve of the spine is maintained while sitting.Â
Sitting for long periods without proper lumbar support can cause the lower back to flatten, leading to discomfort and even chronic back pain.Â
These cushions are typically placed in the small of the back, providing gentle pressure that encourages proper spinal alignment and relieves pressure from the discs and muscles.Â
Lumbar support cushions are especially beneficial for office workers who sit for extended periods and may not have built-in lumbar support in their chairs.
