Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Despite several methods have successfully addressed this increased responsiveness of nociceptive neurons in the central nervous system, there is a lack of consensus about how to systematically perform them and those that are more appropriated for different syndromes. Therefore, investigating appropriate simple methods to assess clinical manifestations of central sensitization is relevant in the assessment of fibromyalgia.
The present study aims to investigate the pain response after suprathreshols pressure stimulation in fibromyalgia subjects compared with healthy volunteers.

Fibromyalgia
Suprathreshold pain stimulation
Suprathreshold pain stimulation will be applied in the infraspinatus muscle (point equidistant between the midpoint of the spine of the scapula, the inferior angle of the scapula and the midpoint of the medial border of the scapula) with a pressure algometer (Force Ten ™, Wagner Instruments, USA). Four suprathreshold pressure stimulations (pressure pain threshold + 20%, +30%, +40% and +50%) will be made for 60 seconds, with a minimum rest of 5 minutes between each stimulation.
The sequence of stimulation (ascending or descending) will be randomized.
Healthy volunteers

Four suprathreshold pressure stimulations (pressure pain threshold + 20%, +30%, +40% and +50%) will be made for 60 seconds, with a minimum rest of 5 minutes between each stimulation.
