Could a Feedback Device Help Manage Work-related Shoulder Disorders?

Plain-language summary

Work-related shoulder pain is a common problem with significant socio-economic repercussions. The impact of these disorders on workers is considerable, particularly in terms of pain, disability and reduced quality of life. Several occupational factors may explain the onset of these disorders, such as changes in the work environment, physical demands, psychosocial factors specific to the occupational context and the age of workers. The lack of quantitative measurement tools to assess the physical demands of work over an extended period of time is sorely felt. Recently, our team developed a wearable feedback device, similar to a watch worn on the arm, which measures shoulder movements and muscle activity, transforming this real-time data into clinical indicators. These indicators provide immediate feedback to workers, enabling them to better understand the physical demands of their tasks and adapt accordingly. If this device proves effective in reducing physical demands, it could become a valuable tool for guiding workplace assessments and interventions. However, this device has not yet been tested on workers with shoulder pain. For this reason, a two-part pilot study is needed to understand user needs, assess ease of use and the feasibility of implementing the device. The first component will consist of a pilot clinical trial involving 42 workers suffering from shoulder pain, divided into two groups: one group will use the feedback device for 2 weeks, while the other group will continue to work without intervention. The second phase will analyze the experience of participants who have used the device.
