Intervention(s)
|
Twenty five patients with fibromyalgia syndrome, ten patients with unipolar major depression (MD) without pain, and thirty five healthy controls are recruited for the study. Patients undergo functional near-infrared spectroscopy (fNIRS) whilst being subjected to two stimulations:
1. Painful pressure stimulation at the dorsal forearm 2. Verbal fluency test (VFT) to asses cognitive function using memory recall
All patients underwent neurological examination and all subjects were investigated with questionnaires (pain, depression, FMS, empathy).
|
Primary Outcome(s)
|
Muscular pressure pain: fNIRS measurements were performed during the application of painful pressure on the muscle bulk of the finger extensors of the right side using a calibrated algesiometer. The stimulation conditions were as follows: pressure application for two seconds; pause for ten seconds between two stimuli; total of 40 stimuli, i.e. measurement at baseline and up to 8 minutes after first stimulation.
|
Secondary Outcome(s)
|
Verbal fluency test (VFT): The VFT paradigm consisted of three conditions. Subjects were asked to produce as many different nouns as possible a) starting with a certain letter (A, F, and S), or b) belonging to the same category (animals, fruits, and flowers) or c) to name the days of the week as a control condition. Each condition lasted for 30 sec followed by 30 sec rest. Subjects worked on nine blocks in total (3 x letters, 3 x categories, 3 x week days), i.e. measurement at baseline and up to 9 minutes after start.
