Abstract

Repetitive movements, even when small loads are carried, are a significant risk factor for the development of musculoskeletal disorders (MSDs). Since muscle fatigue is considered to be an early indicator of the risk of developing injuries, its detection in the workplace with technologies such as wireless electromyographic (EMG) and inertial sensors could help the development and assessment of preventive and rehabilitative interventions with workers.

The project’s objective is to develop an early detection method for muscle fatigue during repetitive tasks with small loads in the workplace.

The project has three components: observations of five volunteers at their workplace throughout a shift; design and assessment of methods in the laboratory, with the participation of 20 workers; and assessment of muscle fatigue at a workplace.

The results will improve our understanding of the connection between repetitive movements, fatigue and the onset of MSDs.
