Ergonomics refers to the science of restructuring workspaces or modifying tasks in such a manner that they fit the specific needs of the individual and complement their capabilities. An ergonomic workstation setup aids in reducing stress, eliminating injuries related to overuse of muscles, and helping to control ergonomic hazards, one of which is back pain.
Chronic back pain is a common health issue among working individuals, primarily those who have desk jobs. This machinery-induced human disorder’s primary cause is poor posturing resulting from inappropriate workstation setup. Understanding how an ergonomic workstation setup can reduce back pain helps to create an optimal workstation that supports body posture, reduces physical stress, and enhances productivity.
The Science behind Ergonomic Workstations and Back Pain
The vital principle of ergonomics is ensuring that the employee’s workstation suits their needs. Incorrect ergonomic setup can create tension and distort the spine’s natural curvature, leading to musculoskeletal disorders. This condition presents as chronic back pain, neck tension, carpal tunnel syndrome, eye strain and fatigue.
The backbone, or the vertebral column, is S-shaped and designed naturally to absorb shock and support body weight. However, incorrect posture can distort this alignment and may lead to chronic back pain.
Creating an ergonomic workstation setup that fosters proper posture and positioning aids in reducing physical strain and risk factors associated with musculoskeletal disorders.
Designing an Ergonomic Workstation Setup
When planning the ergonomic workstation setup, it’s crucial to assess and adjust the whole work area. The critical components encompass the seat, desk, computer, keyboard and mouse, monitor, lighting, and room temperature.
1. Chair Selection and Adjustment
Purchasing an ergonomically designed chair is vital to promote correct sitting posture. Look for chairs with adjustable seat and armrest height, backrest support, good seat depth and width, and a sturdy five-point base. Adjustable features allow for customization for the user’s comfort and the reduction in curvature distortion.
On adjusting the chair, the feet should rest flat on the floor or a footrest, thighs parallel, and the knees at a 90-100 degree angle. The backrest should support the lumbar curve, with shoulder relaxed and armrests supporting the lower arms while the elbows are close to the body.
2. Desk Adjustment
Standard desks tend to be around 29 inches high; however, the desk should align with the individual’s elbow height during seated work. If the desk or workstation is too low, raise the chair and provide a footrest. The objective is to maintain the forearms, wrists, and hands parallel to the floor for better posture.
3. Computer Positioning
For desktop computers, place the monitor directly in front and at least 20 inches away. The top line of the screen should be at level with the eyes, or slightly below, when looking straight ahead. This positioning reduces the risk of neck strain.
4. Keyboard and Mouse Use
Place the keyboard and mouse close to each other and within easy reach. The user should keep the wrist straight and the elbows close to the body when using them. Positioning them too high or too low might strain the shoulder and wrist muscles, inadvertently affecting posture and causing back pain.
5. Lighting and Temperature Adjustments
Ensure the workstation lighting is suitable and does not cause glare on the computer screen that can strain eyes and lead to a hunched posture. Also, the work environment should be at a comfortable temperature. Too cold, and muscles may become stiff, leading to poor posture and back pain.
Lesson from Ergonomics
The key lessons in ergonomics are about understanding and designing the working environment to fit the user, not vice versa. An ergonomically optimized workstation leads to greater comfort, increased productivity, and most significantly, reduces the risk of discomfort and chronic pain, primarily back pain.
Workers can improve their quality of life and work by practicing good posture and setting up their workstation ergonomically. Employers realize the financial saving they make from reduced sickness absence and higher productivity is in millions every year.
In conclusion, investing time and resources to create an ergonomic workstation setup contributes to both physical health and work productivity. Reduced risk of musculoskeletal disorders such as back pain is a holistic approach to a healthier and more productive work environment.
Constant mindfulness and re-evaluation are essential as altering one component of an ergonomic workstation setup can create a domino effect on other parts. Hence, each element needs to be cohesive with the others for an overall ergonomic setup. A regular pause for stretching and movement exercises also contributes to overall well-being and a reduction of backpain.
