Back or shoulders? Only 10% of workers at risk on both fronts - What does this mean?

555 Views
 

Musculoskeletal disorders (MSDs) are a major cause of absenteeism, lower productivity and reduced quality of life for affected workers.

To prevent MSDs, we need to be able to measure risk factors. That's why we designed LEA, a postural analysis application that works simply from a video captured with a smartphone.

LEA makes it quick and easy to identify at-risk postures, based on pose estimation algorithms and the ergonomic RULA method.

In this newsletter, we share with you the lessons learned from LEA.

Back or shoulders? Only 10% of workers are at risk on both fronts.

LEA is widely used in France and the rest of the world. More than 30,000 analyses have already been carried out by you, LEA users.

We've noticed that 37% of the videos show high postural risks for the back, across all industries and countries.

A further 23% showed postural risks to the shoulders.

Slightly more than one video in three shows a situation involving risk to the back, and around one video in four shows a situation involving risk to the shoulders.

On the other hand, only 10% of filmed scenes show situations involving both back AND shoulder risks.

A need for targeted solutions

These data underline a crucial point: postural problems are not necessarily global, but often specific to a joint or area of the body.

This distinction is important when it comes to adjusting preventive solutions. For example, repetitive tasks involving excessive strain on the trunk can lead to low-back pain, while those involving the arms can generate shoulder tension. The purpose of this analysis is therefore to target actions on critical areas in order to optimize MSD prevention.

This observation feeds into a broader reflection on ergonomics in the workplace, where we should not be looking for generic solutions, but rather for specific, targeted interventions.

HAPO exoskeletons: the right response

To meet these specific needs, we believe it's appropriate to design non motorized exoskeletons, each designed to reduce stress on a particular area.

For example, an exoskeleton for the back helps support efforts linked to awkward trunk postures, while one for the shoulders relieves repetitive efforts linked to load handling.

Each exoskeleton is designed to address a specific, identified problem.

This approach makes it possible to respond to needs with agility and controlled costs, while reducing fatigue and postural risks. In the long term, the aim is to promote well-being in the workplace while maintaining productivity.

Beyond simple posture

Of course, in addition to specific solutions for each body zone, it is essential to consider the overall organization of the workstation. The frequency of tasks, the duration of risky postures, and the environment can also contribute to the onset of MSDs.

A holistic approach is therefore recommended, combining technical solutions such as exoskeletons, with organizational adaptations to reduce gestures and postures.

You can contact our advisors for help interpreting your LEA analyses, or if you would like to go even further in analyzing your workstations.
