At the end of this module, you will be able to:
- Define ergonomics and musculoskeletal disorders (MSDs)
- Identify MSD risk factors
- Identify MSD symptoms and prevention
- Describe proper lifting technique
The following key questions are answered in this module:
What is a musculoskeletal disorder?
An injury or illness that affects the nerves, tendons, muscles, and/or supporting structure of the body. These are known as MSDs and often occur at the workplace.
What is ergonomics?
The science of fitting the workplace to the worker, instead of the worker to the workplace, to reduce the risk of MSDs.
What are MSD risk factors?
Motion-based activities, the physical work environment, and social and psychological factors.
What are some motion-based risk factors for MSDs?
Awkward postures and positions, forceful exertions, repetitive motions, duration of exertion, vibration, and contact stress.
What are some MSD symptoms?
Muscle aches; sudden, stabbing pain; weak, numb, burning, and/or tingling sensations; cramping; and stiffness.
What can be done to reduce the risk of MSDs?
Engineering controls, administrative controls, proper lifting and handling techniques, and strengthening.
Below is a transcript of the video sample provided for this module:
Every year, hundreds of thousands of workers are diagnosed with Musculoskeletal Disorders or MSDs. MSDs are injuries or illnesses that affect the nerves, tendons, muscles, and supporting structures of the body. These injuries include sprains, strains, inflammation, degeneration, tears, pinched to nerves or blood vessels, bone splintering, and stress fractures. Many of these problems develop gradually and result in chronic injuries, although sudden events such as trips or falls may also lead to an MSD. This module discusses the risk factors for MSDs present in an industrial setting, and how to reduce those factors.
