Brief Summary

The goal of this feasibility study is to learn if a work environment program to address musculoskeletal disorders and pain, can be implemented and accepted by employees with physical demanding work tasks. The main question it aims to answer is:

• 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

Outcome Measures

Primary Outcomes (1)

• Acceptability

  The theoretical framework of acceptability questionnaire will be used to evaluate acceptability as well as interviews guided by the acceptability framework.

  From enrollment to the end of the 10 week-intervention period

Interventions

GLAD intervention BEHAVIORAL

The intervention consists of two components: 1. 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). 2. 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.
