What does WMSDs stand for?
work-related musculoskeletal disorders
What are WMSDs ?
Are injuries to soft tissues of the body and joint such as muscles, tendons, ligaments, cartilage, and nerves
How do WMSDs typically develop?
Develop gradually over time through repeated exposure to risk factors such as bending, lifting, reaching, twisting, or overexertion, leading to cumulative tissue damage rather than a single traumatic event.
What is a risk factor?
A risk factor is a characteristic of an individual, a work task, or work environment that increases the risk of injury.
What are the general types of risk factor
for WMSDs
1-. Individual risk factors
2-. task related risk factors
3-. psychosocial risk factors
What are intrinsic (individual) risk factors for WMSDs? and examples
a characteristic of an individual such as age, sex, obesity (anthropometry), acute trauma, and congenital conditions
What are extrinsic (task-related) risk factors for WMSDs?
a physical characteristic of how a work task is done on the work environment.
What are some examples of a task-related risk factors
- high force exertions
- highly repetitive work or static work
- Awkard/extreme posture
- vibration
- contact mechanical stress
- environmental stress
What are psychosocial risk factors for WMSDs? and examples
They are related to the mental and social environment. some examples are mental stress, overbearing supervision, poor job security, poor interactions with co-workers, lack of emotional support.
Which task related risk factors did we frequently see ?
- repetitive movements
- extreme movements of posture
- prolonged postures
- vibrations
- forceful exertions
- prolonged periods of standing
- hands over the head
what commonalities did we see among prevention and control of these WMSDs?
- vary posture/ movements
- stretching
- minimize extreme movements of postures
- job rotation or job enlargement
- protective materials to absorb vibration
- reduce forceful exertions
