From the Research
Fixed postures are a significant contributor to the development of Work-Related Upper Limb Disorders (WRULD), as they can lead to sustained muscle contraction, reduced blood flow, and increased risk of inflammation and tissue damage. According to a study published in 2018 1, physical risk factors for WRULD include repetition, duration, working in awkward and static positions, and forceful movements of the upper extremity and neck. The study found that ergonomic interventions, such as arm supports and alternative computer mouse designs, can reduce the incidence of neck or shoulder MSDs.
Key Risk Factors
- Repetition
- Duration
- Awkward and static positions
- Forceful movements of the upper extremity and neck
Prevention Strategies
- Implementing regular microbreaks (30-60 seconds every 20-30 minutes)
- Workstation adjustments to support neutral postures
- Task rotation to vary muscle use
- Stretching exercises throughout the workday
A study published in 2012 2 found that a combination of physical rehabilitation and ergonomic interventions can significantly reduce pain and improve functional capacity in patients with WRULD. The study suggested that a self-administered physical rehabilitation program, combined with ergonomic workplace improvements, can be an effective treatment for WRULD.
Treatment Approaches
- Physical rehabilitation programs
- Ergonomic workplace improvements
- Self-administered exercises and stretches
Overall, the evidence suggests that fixed postures can contribute to the development of WRULD, and that prevention strategies and treatment approaches that address ergonomic risk factors can be effective in reducing the incidence and severity of WRULD.
