Workplace program aims to prevent pain in physical jobs
NCT ID NCT07466680
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a workplace program called GLAD can be used to prevent muscle and joint pain in blue-collar workers. 70 workers and safety professionals took part in an 8-week program with education, ergonomic changes, and exercises. The main goal was to see if workers would accept and use the program, not yet to prove it prevents pain.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GLAD intervention (behavioral program with education, ergonomics, and exercises)
- What this could lead to
- If successful, this could lead to a practical program that reduces pain and injury risk for workers with physically demanding jobs.
- What could go wrong
- This is a small feasibility study, not a large trial. It only measures acceptance and practicality, not whether the program actually prevents pain long-term.
