What is musculoskeletal injury?

Musculoskeletal injury, or MSI for short, is the term used to describe soft tissue injuries that are commonly known as sprains or strains. For example, a strained back is an MSI.

MSIs often occur in the lower back, but they can also occur in other parts of the body, such as the shoulders, wrists, or knees. MSIs occur when the demands of work exceedthe capacity of the body.
