Oxygenation and myoelectric activity

Differences in oxygenation and myoelectric activity in the forearm and shoulder muscles of healthy subjects versus patients suffering from chronic shoulder or forearm muscle pain

The mechanism behind the occurrence and maintenance of work-related muscle pain is not known. 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 investigates the relationship between NIRS-parameters and the muscle electrical activity (EMG) for the forearm and shoulder muscles of a group of healthy subjects compared to a group of subjects suffering from work-related muscle pain.

This study hopes to provide insight into how the pain develops and is maintained so that better methods for prevention, diagnosis and treatment can be developed.
