Study Notes

Ergonomics in the Office

Ergonomics is the process of fitting the work to the worker. It considers the fit between a person, their tasks, tools, and work environment.

What Happens If You Do Not Practice Good Office Ergonomics?

Employees can suffer from health problems like pain, tingling, numbness in hands, fingers, or wrists.
Other issues might include swollen or stiff joints, pain in shoulders, neck, or back, muscle cramps, or vision problems.

Musculoskeletal Disorders

Musculoskeletal disorders are discomforts that build over time in muscles, tendons, ligaments, joints, or nerves. This can include strains, sprains, or inflammation.
These disorders can be relieved with ergonomic office practices.

Office Health Hazards

Poor posture, awkward posture, sustained position, repetition of motions, and constant pressure are significant office hazards.
These hazards lead to office syndromes including eye hyperemia, headaches, shoulder pains, backaches, neck pain and tunnel syndrome.

Benefits of Ergonomics in the Office

Reduced injuries
Improved productivity
Improved work quality
Improved safety culture

Office Ergonomics Awareness and Prevalence of Musculoskeletal Symptoms

The mean knowledge score for office ergonomics among office workers in one specific university was 7.9 ± 4.0 out of a total of 28. This suggests a lack of awareness regarding ergonomic principles.

Ergonomic Risk Factors in the Office

Awkward posture
Sustained posture
Repetition
Contact stress leads to discomfort and musculoskeletal disorders.

Awkward Posture

Awkward posture refers to any body position that deviates from neutral posture. This avoids stress on parts of the body, like the spine.
An example of awkward posture is hunching or slouching over work.
Maintaining posture in any activity demands careful consideration, often overlooked in workspaces.

Repetition

Repetition of the same motions can cause strain on muscles and joints.
Everyday tasks like typing or using a mouse repeatedly can cause issues with hands and wrists.

Contact Stress

Contact stress is pressure from hard edges or surfaces.
This can interfere with circulation and nerve signals.
An instance of contact stress can be a hard desk edge against the forearm.

Tips for Office Ergonomics

Proper sitting posture
Correct monitor setup
Correct keyboard and mouse placement
Establish good work and rest schedules

Setting Up Your Workspace

Correct monitor height (at or slightly below eye-level)
Proper keyboard and mouse positioning (elbow at 90-degree angle)
Document holder positioned between keyboard and monitor
Correct chair adjustments to accommodate the worker.

Proper Sitting Posture/Distances

Relaxed shoulders
Proper back support
Arms at a 90-degree angle (horizontal to the body).
Feet flat on the floor
18-24 inches distance from eyes to monitor.
25-30 inches distance from monitor to desk.

Ergonomic Office Chairs

Adjustable headrests
Adjustable backrests
Lumbar support
Adjustable armrests
Comfortable cushions
Adjustments for seat height and depth
Stable five-wheel base

Example of Footrests

Footrests can help maintain a comfortable position to promote blood flow to the lower legs and feet

How to Set Up a Monitor

Ensure the top of the monitor is at or slightly below eye level.
Position the monitor roughly an arm's length away.

Which Monitor Set?

Includes options for single PC monitor, dual PC monitors, single Mac monitor, and monitors combined with laptops.

Position of Monitors

Position different monitor types accurately for comfortable use and to avoid strain.

Single Mac Monitor Positioning

These monitors need to be elevated differently for proper use, and the user needs to adjust their positioning.

Laptop Only Position

Use of a laptop alone as a primary monitor requires adjustments to maintain comfortable keyboard/mouse placement and eye position relative to the monitor. The posture should allow for comfortable hand and arm positioning.

Ways To Avoid Ergonomic Mistakes

Avoid placing monitors in front of windows
Avoid placing laptops in front of freestanding monitors

Keyboard and Mouse Setup

Keyboard and mouse should be at the same height and close to the body to allow elbows to be at a 90-degree angle.
Armrests should support maintaining relaxed shoulders, and the user should be able to easily reach the peripherals.

Keeping Wrists Neutral

Keep wrists flat when using the keyboard
Avoid angling wrists backward during use.

Wrist Rest Usage

Avoiding pressure on the wrists when typing or using a computer is a key to minimizing carpal tunnel.

Work/Rest Schedules

Maintain a balance between work and rest time. Sitting for extended periods should be broken up with standing or walking.

Counting Hours Spent Sitting

Analysis of an average day (with activities such as working, chores, and relaxation) to demonstrate the number of hours spent in a sitting position.

Effects of Sitting All Day

Extended periods of sitting can affect the neck, trap muscles, spinal discs, and hips, potentially causing pain and discomfort.

Inactive Lifestyle Impacts

Health problems like high blood pressure, heart attacks, diabetes, cancer, inflammation, weaker bones, and physical disability can occur from a sedentary lifestyle.

20-8-2 Office Rule

20 minutes sitting, 8 minutes standing, 2 minutes moving. This cycling can reduce strain and maintain balance.

Additional Tips at Work

Getting up and moving around periodically
Performing stretching exercises
Using the stairs
Have walking/standing meetings
Utilizing different equipment like treadmill desks.

Home Improvement Tips

Maintaining activity while watching TV or other screen time
Walking or running around as breaks or part of daily life routines.
Incorporating hobbies like gardening, which involve physical activity.

Body Care

Treat your body with respect. Proper ergonomics promote overall wellbeing and reduce strain.
