Role of Ergonomics and Orthopedic Health in the Workplace

Introduction:

We are living in the digital era. Due to our occupations, many of us spend a lot of time in the office or workplaces like factories. This lifestyle change is related to the onset of several workplace-related disorders. Such conditions can easily be called diseases of modern times or the digital era. Work-related musculoskeletal disorders (WMSDs) are one of the most common disorders seen in workplaces.

What Are the Orthopedic Conditions Related to the Workplace?

Orthopedic conditions that appear due to workplace conditions are known as work-related musculoskeletal disorders (WMSDs). According to defecation put forward by the US Department of Labor, these injuries are related to muscles, nerves, tendons, joints, cartilage, and spinal disc injuries. They are caused by exposure to risk factors in offices and factories. These are chronic, painful conditions attributed to office ergonomics that lead to disabilities and physical impairments.

Risk Factors:

The risk factors associated with work-related musculoskeletal disorders (WMSDs) are:

1. Prolong sitting and maintaining the same positions.

2. Continuation of the same movement for a longer duration.

3. Inadequate rest periods between tasks are due to a fast work pace.

4. Nutritional deficiencies.

5. Doing repetitive, forceful work.

Pathophysiology:

All these risk factors lead to inflammatory changes. These changes lead to accumulating inflammatory mediators, like in joint spaces. These inflammatory mediators cause joint pain and swelling. Chronic injury to the joint space ultimately leads to fibrosis and degeneration of the joints. All these factors cause atrophic changes in the muscles. As a result, muscle fiber loss and muscle fibrosis are observed. One of the main reasons for the pain in the joint is a neural injury. These injuries are caused by overstretching of the joints and degeneration of the joints, which lead to compression of the nerve fibers.

What Are the Common Orthopedic Complications in the Workplaces?

Several work-related musculoskeletal disorders (WMSDs) are seen in the workplace.

These conditions are:

1. Arthritis: This is a chronic inflammation of the joints. This condition can be caused by factors like inflammation and auto-immune conditions. However, osteoarthritis is commonly seen in weight-bearing joints like hip and knee joints in workplaces. The deterioration of the joint's protective covering characterizes this degenerative joint disease. These conditions result in intense joint pain, limited mobility, and difficulties with walking.

2. Carpal Tunnel Syndrome is one of the most common neuropathic conditions. It is caused by compression of the median nerve within the carpal tunnel (the passage between the bones of the palms of the hands), which causes pain and numbness in the fingers.

3. Neck Pain: The weakening of muscles due to overuse is the primary cause of this condition. Prolonged periods of sitting in the same position and poor posture while working, driving, and walking can also contribute to developing muscle pain. Additionally, muscle overstretching and damage to muscle fibers can result from these conditions. Also, degenerative changes in the cervical vertebrae due to wear and tear are significant in muscle pain. Excessive wear and tear in the cervical vertebrae can lead to the development of bone spurs along the edges of the vertebral bodies, which can cause compression of nerves and spinal discs. As a result, patients may experience intense pain due to nerve fiber compression.

What Is Ergonomics?

Ergonomics is the science or study that deals with situations or elements around human beings. Office ergonomics refers to the situation, environment, and aspects of the office. In the workplace, several elements impact human health, including orthopedic health. Ergonomics in the workplace include sitting conditions, sitting posture, the nature of work, the work duration, and the equipment used.

What Is the Importance of Ergonomics in Improving Orthepetic Health?

Several modifications in office ergonomics can improve orthopedic health and prevent orthopedic complications.

These improvements are,

Proper Desk Position: Several office employees experience neck, shoulders, or lower back discomfort due to non-ergonomic chairs and improper desk heights. For a regular computer, the top of the screen should be appropriately aligned with or slightly below eye level.

The following measures can be taken to ensure proper chair positioning.

• Seating at a Proper Height: While sitting, the feet should comfortably rest on the floor with knees bent at a 90-degree angle

• Armrests: The elbows should remain at a 90-degree angle to prevent shoulder or wrist strain.

• Back Seat Depth and Tilt: There should be enough space between the person and the armamentarium. A two- to three-finger gap should be between the seat edge and the knees.

Use of Ergonomics Furniture:

Ergonomic furniture promotes functionality and comfort for human use, thereby minimizing the likelihood of musculoskeletal issues, joint pain, back problems, neck discomfort, arthritis, organ constriction, and poor blood circulation.

For furniture to meet ergonomic standards, it should:

• Facilitate natural body movements without constraints.

• Maintain the natural S curve of the spine instead of forcing it into a C shape.

• Allow for easy adjustments to accommodate a wide range of individuals.

• Encourage increased physical activity throughout the day when feasible.

• Prioritize usability over aesthetics or convenience.

• Alleviate pressure on joints, bones, and muscles.

Some common features found in ergonomic furniture include:

• Adjustable height to ensure proper alignment of hips and knees while seated.

• Swivel screen monitors come with anti-glare filters to protect the eyes.

• Support for keyboards and mice to prevent conditions like carpal tunnel syndrome.

• Chair arms with 180-degree adjustments to mimic natural limb movements.

• Weight-activated seat mechanisms for optimal support.

• Fabrics that regulate temperature for added comfort.

Taking Breaks and Exercises:

Taking breaks between work prevents muscle and tendon injuries. Stretching exercises are also helpful in such cases. These exercises cause the lengthening and elongation of specific groups of muscles and tendons. These exercises improve joint movement, muscle-tendon flexibility, and range of motion. One of the leading chronic effects of flexibility exercises is muscle strength and power improvement. Stretching exercises are helpful in postural correction.

These exercises are practical for improving posture in people with neuromuscular disorders. These exercises improve neuro-muscular coordination and improve muscle coordination. Apart from this, educating individuals about the importance of ergonomics is essential. Obesity control is important for improving body posture. Traditional exercises like Tai Chi and yoga also prevent orthopedic conditions.

Conclusion:

Prolonged sitting and muscle overuse often lead to orthopedic complications like work-related musculoskeletal disorders (WMSDs). However, changes in office ergonomics can prevent such conditions. These changes include proper sitting position, stretching, rest, and ergonomic furniture.
