Outcome Measures

Primary Outcomes (1)

  • Referred pain induced area after suprathreshold pressure stimulation

    After each stimulation (120%, 130%, 140% and 150%), the subject should draw the induced pain area on a digital bodychart using the Navigate Pain application (Navigate Pain, Aalborg University, Denmark). The size of the areas of referred pain will be extracted in pixels.

    Inmediately after each stimulation

Secondary Outcomes (2)

  • Pain intensity

    Inmediately after each stimulation

  • Body regions afected by pain after suprathreshold pressure stimulation

    Inmediately after each stimulation

Study Arms (2)

Fibromyalgia

Device: Suprathreshold pain stimulation

Healthy volunteers

Device: Suprathreshold pain stimulation

Interventions

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.
