Musculoskeletal Disorders (MSDs)
Musculoskeletal Disorders (MSDs) are injuries or conditions that affect the muscles, tendons, ligaments, joints, or nerves. They are often caused by repetitive movements, awkward postures, or excessive force. Implementing ergonomic solutions—such as properly designed workstations, tools, and task modifications—can help prevent MSDs.
The High Cost of MSDs
- MSDs represent over 30% of all workers’ compensation claims.
- Each year, they account for $15–20 billion in workers’ compensation costs, with total direct costs reaching up to $50 billion.
- Recovery from conditions like carpal tunnel syndrome can take an average of 28 days.
This course provides practical strategies to reduce the risk of repetitive stress injuries in common construction tasks. While some solutions may require collaboration with building owners or general contractors, many can be implemented directly by workers and supervisors.
