ARPE Training for Manual Handling Workers: A Quasi-Experimental Study on Ergonomic Knowledge and Practice

The goal of this study is to evaluate whether an Augmented Reality-based ergonomic training module (ARPE) can improve ergonomic knowledge, self-prevention, and self-evaluation practices among adult manual material handling (MMH) workers in warehouses. The main questions it aims to answer are:

Does the ARPE training module improve workers' ergonomic knowledge?

Does it enhance their ability to prevent and assess risks of work-related musculoskeletal disorders (WMSDs)?

Researchers will compare an intervention group using the ARPE module with a control group receiving traditional training based on national ergonomic guidelines to see if the AR module leads to better outcomes.

Participants will:

Attend a briefing and use the ARPE training via the MAKAR XR app

Complete self-assessment questionnaires at baseline, week 1, and week 6

Receive reminders and follow-ups through WhatsApp
