The principal study aims at evaluating the efficiency of rTMS maintenance sessions on the clinical effect of a rTMS cure in fibromyalgic subjects. This complementary study consists in the evaluation of the experimental sensitivity to mechanical pain (pressure application on the forearm) of subjects presenting fibromyalgia before and after rTMS treatment (21 days), and to put the results in relation to the clinical improvement and the psychometric evaluations (depression,fibromyalgia impact questionnaire, catastrophism).

Condition Intervention
Other: experimental pain induction

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Official Title: Experimental Pain Sensitivity of Subjects With Fibromyalgia Before and After rTMS Treatment in Relation to the Clinical Improvement

Further study details as provided by Centre Hospitalier Esquirol:

Primary Outcome Measures:
  • Variation in the Visual Analogic Scale (VAS)score after fixe pressure application (160 kPa) between the first rTMS session (T0) and the last rTMS session (T21)in relation to clinical improvement [ Time Frame: 21 days ] [ Designated as safety issue: No ]

    The clinical improvement is defined as :

    30% decrease in the general painful state evaluated by VAS between T0 and T21 and response to the Patient's Global Impression of Change ≥ 6 at T21

Secondary Outcome Measures:
  • variation in the experimental pain feeling (VAS) between T0 and T21 in relation to treatment group [ Time Frame: 21 days ] [ Designated as safety issue: No ]
  • variation in experimental pain feeling between T0 and T210 (the end of rTMS maintenance sessions) [ Time Frame: 210 days ] [ Designated as safety issue: No ]
  • variation in Beck Depression Inventory scores between T0 and T21 [ Time Frame: 21 days ] [ Designated as safety issue: No ]
  • variation in Fibromyalgia Impact Questionnaire score between T0 and T21 [ Time Frame: 21 days ] [ Designated as safety issue: No ]
