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.
