Part 1: Introduction to Musculoskeletal Injuries

Musculoskeletal injuries (MSIs) are injuries to the muscles or to the skeletal system. These injuries develop over time. A single repetition of an action may seem harmless, but multiple repetitions add up and place stress on the body, eventually resulting in injury. There are various methods of completing tasks at work, and some methods are more likely than others to result in MSIs.

Risk factors are risky actions that may result in musculoskeletal injuries. There are many risk factors of MSIs; some of which will be covered in the following parts. The risk factors that will be covered are:

1. Awkward Postures
2. Force
3. Repetition
4. Duration
5. Local Contact Stresses
6. Environment
