Muscle fatigue detection and soft tissue characterization: MyoSense and PELVITRACK projects

The Research Center conferences aim to raise awareness within the community about new topics and technological innovations. 

Aimed at a wide audience—students and researchers from all disciplines—they draw on the multidisciplinary expertise of the MIPS Center, partner centers and structures, and national and international teams.

They are held on the first Friday of each month at 11:30 a.m. and are followed by a buffet lunch, providing an opportunity to continue discussions.

Speakers:

• Florence Azaïs, LIRMM
• Sarah Iaquinta, LMGC/IMT Mines Alès
• Stéphane Perrey, Euromov Digital Health in Motion

Summary

The conference will present two innovative research projects focusing on understanding and monitoring muscle fatigue and the mechanical characterization of soft tissues.

MyoSense Project: a multimodal approach to understanding and monitoring muscle fatigue
Muscle fatigue, characterized by a decrease in the ability to generate force after prolonged activity, can lead to injuries and musculoskeletal disorders. The MyoSense project combines several non-invasive measurement techniques (sEMG, NIRS, BIS) to better understand the mechanisms of fatigue and ultimately develop a portable monitoring device. The presentation will outline the context of the project, the experimental protocol, and the initial results obtained.

PELVITRACK project: multiscale mechanical characterization of soft tissues – results and prospects
Perineal tears occur in nearly 90% of vaginal deliveries in Europe and can lead to long-term complications (incontinence, chronic pain, etc.). The PELVITRACK project (EIC Pathfinder, 2025–2029) aims to predict and prevent these injuries using quantitative risk indicators derived from a multidisciplinary study of the mechanical behavior of soft tissues. Current results and future prospects will be presented.

In a dynamic linked to the PTLs, the MIPS Division teams combine their skills to meet these challenges.
