Repetitive motion injuries (RMIs) are common workplace hazards that come from performing the same motions over and over again. The repetition may lead to strained muscles, tendons, and nerves. Understanding and addressing these injuries can help maintain a healthy, productive workforce and prevent long-term health complications.
What is a Repetitive Motion Injury?
A RMI occurs when continuous repetitive movements strain specific body parts. The movement leads to inflammation, pain, or even permanent damage. Common repetitive motion syndrome examples include injuries in the wrists like carpal tunnel syndrome. It may also occur in the shoulders as a rotator cuff injury.
Other conditions such as cartilage damage, tendinitis, and bursitis develop gradually but can severely affect productivity and quality of life.
Causes of Repetitive Motion Injuries
Constant repetitive movements at work can lead to injuries because muscles are overused and fail to recover fully. Common causes include:
- Typing for long hours
- Repeated lifting of heavy objects
- Awkward postures for extended periods
- Using vibrating tools frequently
The 2021 Workplace Safety Index by Liberty Mutual lists the top ten causes of workplace injuries.
Symptoms of Repetitive Motion Injuries
RMIs typically begin subtly, with mild discomfort. However repetitive stress causes it to worsen over time. Common symptoms include:
- Persistent pain or aching in affected areas
- Numbness/tingling in hands, fingers, or joints
- Reduced range of motion or stiffness
- Muscle weakness
Ergonomic Issues and Problems Related to RMIs
Ergonomics focuses on the relationship between people and their work environment. Likewise, ergonomic related injuries in the workplace often stem from uncomfortable seating, improper workstation setup, poorly designed work tools, inadequate lighting, or improper chair height. All of these can exacerbate an already present strain from repetitive activity. To lessen injury, some ergonomic best practices to consider include:
- Adjusting chair height and keyboard placement to reduce strain from repetitive tasks
- Arranging workspaces to keep frequently used items within easy reach
- Utilizing adjustable chairs, desks, and monitors
- Implementing job rotation to reduce overuse of specific muscles
Ergonomics play a huge role in preventing musculoskeletal disorders and work-related injuries. To learn more about the impact of ergonomics at work, take a moment to review OSHA’s ergonomic guidelines.
Preventing Repetitive Motion Injuries
Avoiding repetitive strain injury takes intentional effort. To prevent RMIs, consider implementing the following practices:
- Take frequent breaks to rest muscles.
- Use ergonomic tools to reduce strain on joints.
- Stretch regularly to maintain flexibility.
- Adjust the desk and chair height for optimal posture.
- Use wrist supports when typing or working with computers.
The Role of Employers in Preventing Ergonomic Injuries
Can an employer be liable for ergonomic injuries?
Legally, employers are obligated to provide safe, ergonomically sound work environments. Effective programs should prioritize office safety and ergonomics to prevent injuries and reduce legal liabilities. Tools like the Modjoul SmartBelt help monitor employee movements and detect unsafe patterns that could lead to injuries.
Repetitive motion injuries are preventable with proper ergonomic practices and awareness. Understanding the causes, symptoms, and the role of workplace ergonomics allows both employees and employers to work together and create safer environments.
