From the Research
Yes, WRULD (Work-Related Upper Limb Disorder) can affect the dominant hand. The dominant hand is particularly vulnerable because it typically performs more repetitive movements and bears greater force during work activities. WRULD encompasses conditions like carpal tunnel syndrome, tendonitis, and tenosynovitis that develop from repetitive movements, awkward postures, forceful exertions, and insufficient rest periods during work tasks.
Key Points to Consider
- A study published in 2022 1 found that patients with peripheral nerve injury with dominant hand injury do not compensate with their unaffected nondominant hand, even if it is more dexterous.
- Another study from 2016 2 showed that common hand disorders such as carpal tunnel syndrome, de Quervain's tenosynovitis, osteoarthritis, and trigger finger affect the dominant and nondominant hands in roughly equivalent proportions, whereas lateral epicondylitis is more common on the dominant side.
- Treatment typically includes rest, anti-inflammatory medications, physical therapy, ergonomic workplace modifications, and in some cases, splinting or bracing the affected area.
- Prevention strategies include taking regular breaks, proper positioning of equipment, maintaining neutral wrist positions, alternating tasks when possible, and strengthening exercises for the hands and arms.
- The dominant hand's increased use creates greater mechanical stress on tendons, muscles, and nerves, making it more susceptible to microtrauma that can accumulate over time and lead to tissue damage and inflammation. Some older studies, such as those from 2005 3 and 2002 4, also investigated the impact of hand dominance on strength and daily activities, but the most recent and highest quality study 1 provides the most relevant evidence for clinical decision-making.
