The global approach to reduce the risk of Musculoskeletal Disorders (MSDs) is necessary because, although the latter are associated with biomechanical stresses, other factors are involved: organizational, psychosocial, environmental factors, etc.
Thus, KIMEA objectifies the risk of MSDs from a biomechanical point of view. In addition, ergonomists establish cause-and-effect links with other factors. It is by taking all these factors into account that the development recommendations will have lasting benefits.
MSDs are therefore multifactorial health impairments with a professional component. To these factors should be added stress, as well as individual factors such as aging or medical history, which contribute to the development of MSDs.
Our ergonomists can analyze all these risk factors by intervening in your organization during a service.
The main biomechanical risk factors are:
- Repeatability of gestures
- Efforts / load port
- Work requiring precise and fine movements
- Uncomfortable and/or maintained postures
- Organizational factors
The organization of the position plays a major role in the employee’s activity. Varying tasks or lack of breaks, excessive working hours, dependence on the pace of a production line, lack of collaboration, are all organizational factors that increase MSD risk.
Each individual has unique characteristics (health status, height, age, weight, gender). These elements can facilitate the development of MSDs.
Psychosocial factors are related to:
- Time pressure
- Excessive workload
- Lack of autonomy/self-control of one’s work
- Social support from colleagues and/or hierarchy
- The professional future
These factors can be a source of stress for the employee.
Stress itself can have a negative impact on activity because muscle tension increases, recovery time takes longer than normal, and support and clamping forces are more acute. All this increases the employee’s MSD risk.
