What is it about?
Myanmar migrant workers in Thailand's seafood processing industry perform repetitive tasks such as shrimp peeling while standing for long shifts, leading to pain in their hands, necks, and backs. Because of language barriers, demanding schedules, and limited healthcare access, standard health programs rarely reach them. In this study, we worked directly with 29 Myanmar workers — organized by their years of work experience — alongside workplace managers and international physical therapy experts, to co-design a health study that would actually fit these workers' lives. Workers told us they preferred receiving health information through Facebook videos they could watch in their limited free time, and that any exercises needed to work in small dormitory spaces, with no equipment, outside work hours. These insights shaped a four-week Facebook-based program featuring 12 progressive exercises addressing the strain patterns most common in their work. International experts rated the co-designed program as having strong content validity (I-CVI: 0.95–1.00). The paper also documents the ethical challenges we encountered, including protecting workers from potential workplace repercussions and managing power imbalances in the co-design process.

Why is it important?
This paper provides the first documented methodological account of meaningful community co-design with Myanmar migrant workers in Thailand's seafood industry. It challenges the conventional top-down model of health intervention design by showing that even hard-to-reach, vulnerable populations can serve as genuine partners in research — and that doing so produces interventions that are both clinically valid and practically usable. The study is timely: Southeast Asia hosts millions of migrant workers in physically demanding sectors, yet occupational health research rarely involves them as co-designers. Our findings offer a transferable framework for researchers seeking to conduct ethical, participatory research with migrant communities, and demonstrate that digital platforms such as Facebook can bridge the access gap for populations with non-standard schedules and limited mobility. The paper's honest account of ethical tensions — including power differentials and participant protection — adds methodological transparency that is often missing from participatory research reports.
Perspectives
I am a communication scholar, and my role in this project was shaped by a core conviction: that the people most affected by a health problem are also the most qualified to help solve it. What struck me most in this work was how quickly the workers' input reframed our assumptions. We arrived with ideas about what an effective intervention might look like, and the workers redirected us — not away from rigor, but toward relevance. Facebook over workshops. Dormitory-friendly exercises over clinic-based routines. Peer challenges over individual compliance. These were not compromises; they were improvements. I also want to be honest that co-design with a vulnerable population carries real ethical weight. Ensuring workers felt safe to speak freely, without fear of consequences from their employer, required constant attention throughout the process. I hope this paper is useful not only as a methodological resource but as an honest account of what participatory research actually looks like when the power imbalances are real and the stakes for participants are high.
