Digital human ergonomics training for remote office workers: Comparing a novel method to a traditional online format

Area of Science:

• Ergonomics
• Human-computer interaction
• Occupational health

Background:

• Remote work presents unique ergonomic challenges for musculoskeletal health.
• Effective online training is crucial for mitigating risks associated with remote work setups.
• Digital human technology offers a novel approach to interactive training delivery.

Purpose of the Study:

• To evaluate the efficacy of an online ergonomics training program incorporating a digital human.
• To compare the digital human intervention against traditional online training and a control group.
• To assess impacts on musculoskeletal discomfort, knowledge retention, and behavior change.

Main Methods:

• A randomized controlled trial involving 138 remote office workers.
• Three groups: digital human training, traditional webpage training, and control.
• Measurements included self-reported musculoskeletal discomfort, knowledge retention tests, and observed behavior changes.

Main Results:

• Statistically significant improvements in overall behavior change and knowledge retention were observed (p < 0.05).
• Digital human training yielded knowledge retention comparable to traditional training.
• Traditional training demonstrated significant behavior improvement over the control group.
• No significant reduction in musculoskeletal discomfort was found across any group.

Conclusions:

• Digital human technology shows potential for scalable online ergonomics training for remote workers.
• While knowledge retention was comparable, traditional training showed greater behavior change impact in this study.
• Further research may optimize digital human interventions for enhanced behavioral outcomes in occupational ergonomics.
