Introduction
The number of workers suffering from work-related musculoskeletal disorders, estimated to account for 21 to 28 % of all days of occupational sick leaves, is a major health problem for society and workers (1). In addition to other preventive actions, physical activity protocols (PAP) contribute to reduce Musculoskeletal Disorders (MSDs) in workers (2). The nature of the protocol, its implementation, its acceptability and the engagement of workers (3) to the protocol are essential determinants of the effectiveness of the PAP.

Objectives
The aims of the study are to evaluate the feasibility and acceptability of a preventive PAP of 5 minutes named SMS (Strength, Mobility and Stretch) to present the preliminary results, particularly in terms of engagement and the effects at 15 months on the reduction of work accidents (WA), their severity and the number of MSDs.

Methods
A mandatory approach based on 5 minutes of SMS per day worked adapted to job families for all workers of an industrial company (n=250) was implemented from September 2021 through the intervention of a service company. The protocol was:
- Information about this approach to all workers and call for applications to become internal animators (IA);
- 3 weeks: Animation of SMS sessions by the service company;
- 4 x 1 day: Training of 4 groups of IA;
- 2 weeks: Co-animation of SMS sessions by IA and service company;
- 14 months: IA of SMS sessions.

The indicators monitored are the frequency and severity rates of WA, MSDs declared (indicators of the French Medical Health Care System) over the last 5 years, as well as the relative risks and level of engagement.

Results
The share of volunteer workers trained to be IA is 14%. Protocols were followed by all workers and none of them refused.
The first results show a significant drop in 15 months in frequency and severity rates of WA:
- Decrease in the frequency rate from 51.25 to 14.21
- Decrease in the severity rate from 0.96 to 0.45
The relative risk analysis shows a reduction in the risk of WA of 53% and in the risk of minor accidents of 65%. The number of MSDs declared during the mandatory is zero.

Discussion and conclusion
The proportion of volunteer workers trained demonstrates a certain interest in SMS and an appropriation of the approach by workers. This approach requested and organized by the companys management is well accepted by all workers.
According to these initial results, it would seem that 5 minutes of SMS every working day helps reduce WA and MSDs in this industrial environment. Further studies are needed to confirm these results, measure the evolution of the indicators presented and monitor workers engagement over the long term.
