Ergonomics and prevention of MSDs


MSDs? What are they all about?

Musculoskeletal disorders encompass a large set of complaints affecting the soft tissues around the joints and the vertebrae. They are experienced at the wrists, elbows, spine, knees, and among their most frequent manifestations are carpal tunnel syndrome (CTS), tendinitis, and lumbago.


Risk factors


Although each individual’s state of health and characteristics (age, sex, body weight, etc.) clearly play their part, recent studies show MSDs to be the result of a combination of risk factors:

Biomechanical: repetitiveness of body movements, excessive and/or violent efforts, extreme postures and limb angles, exposure to cold, vibrations, etc.

Organizational factors: workstation organization and environment

Psycho-social factors: the way work is perceived by employees, stress created by time pressure, etc.

Every company has its own specific combination of risk factors. That’s why a good grasp of its work situations is required.


NEODITECH solutions


We have been developing ergonomic handling and lifting systems since 2007 in the aim of optimizing postures and reducing the muscular effort applied by operators.


Prevention through ergonomics


The word ergonomics is derived from the Greek “ergon” (work) and “nomos” (laws, rules). Ergonomics can therefore be defined as the science of work from the point of view of adapting work to suit humans (and thereby improving working conditions).

To maintain an objective of always adapting work to suit people, one needs to consider as many aspects of their work as possible: physiological, psychological, social factors, and subjective as well as objective factors.

Better adaptation of work to people results in better operator satisfaction, comfort, and health and makes their operational conduct more efficient. This leads naturally to an increase in company productivity.


MSD in figures


 

MSDs represent 80% of the occupational ailments recorded in France’s state health insurance scheme.

Direct costs of an occupational disease:

Carpal tunnel syndrome 11 000 €
Low back pain 52 000 €
Shoulder stiffness 80 000 €

Direct costs of an accident at work:

Average cost of an AT with a stop of € 3,000
Average cost of a handling AT with stop € 4,500

Indirect costs:

For the employee:
Work stopping
Medical costs (care, hospitalization costs, rehabilitation ...)
Loss of wages
Inability
Back to work

For the company :
Manager's liability
Public liability
Loss of production
Replacement
Training
