- Will the intervention be accepted by the workers?
- It it feasible to implement a workplace intervention to prevent musculoskeletal disorders and pain?
Participants will:
- Implement the intervention
- Participate in the intervention twice a week for eight weeks
- Answer questionnaires and participate in interviews to evaluate the intervention
- Conditions
- Pain, Musculoskeletal Disorders
- Being tested
- GLAD intervention
- Medical subject headings
- Pain, Musculoskeletal Diseases
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GLAD interventionBehavioural
The intervention consists of two components:
- Implementation of the GLAD intervention to the workers at one unit at the participating workplaces. The GLAD intervention consists of 15 modules containing knowledge on pain, participatory ergonomics and physical exercises. Each module last 30 minutes and are delivered by an occupational safety and health professional (OSH).
- Education of the OSH's to deliver the GLAD intervention. The education aim to give the OSH the necessary knowledge, skills and competencies to deliver the intervention to the workers at their workplaces. The education program consists of evidence-based knowledge on pain and management, content of the GLAD intervention and implementation strategies. The education is delivered as an online preparatory work (approximately 1 hour) and a 7-hour course with physical attendance.
