Oxygenation and myoelectric activity

The relationship between oxygenation and myoelectric activity in the forearm and shoulder muscles of males and female

The mechanism behind the occurrence and maintenance of work-related muscle pain is not known. Also not known is why females are more affected than males. Research indicates that disturbed circulation might play a role.

Near infrared spectroscopy (NIRS) is a non-invasive technique that, by way of sending a beam of light into the muscle, is capable of providing information of blood flow, oxygenation and blood volume.

This study involves the following objectives: (1) investigates the relationship between NIRS parameters and the muscle electrical activity (EMG); (2) determines if there are gender differences in NIRS-derived parameters; (3) determines the day-to-day reliability of NIRS-derived parameters for the forearm and shoulder muscles.

We hope to gain insight of some important physiological parameters relevant for studying the mechanism behind work-related muscle pain. Further, we hope to obtain knowledge of the effectiveness of the NIRS method in this regard.
