  Purpose

The objective of the investigators study is to assess conventional repetitive transcranial magnetic stimulation (rTMS) in patients with chronic severe tinnitus. A randomized, double-blind, sham-controlled procedure, with four increasing levels of magnetic "pseudo-dose" has been designed, in order to characterize the effectiveness of rTMS while controlling its safety and tolerability. By combining various rTMS protocols with a twelve-month follow-up, and using an effect modeling, the study aims at: (i) specify the effective values of rTMS parameters, with an adequate tolerance; (ii) determine the expected benefit and the persistence of effect; (iii) assess the practical feasibility of this kind of therapeutic management.

Primary Outcome Measures:
  • Change from baseline in tinnitus perception, as measured over time using a visual analog rating scale (subjective loudness of tinnitus) [ Time Frame: At subject enrollment; daily for 2 weeks before the intervention; before and after each rTMS session, once at the end of each week and at the end of intervention; during follow-up: twice a week for 6 months, and 1 year after the end of intervention ] [ Designated as safety issue: No ]
    The time between enrollment and rTMS intervention will vary from one subject to another (expected average of 4 months); depending on the protocol, the end of the intervention corresponds to the end of week 1, 4, 5 or 20 (first day of rTMS as reference)


Secondary Outcome Measures:
  • Tolerance of rTMS, evaluated through a semi-structured interview on specific and nonspecific adverse events [ Time Frame: After the first rTMS session; before and after each following session and at the end of intervention period; 1, 4 or 5, and 20 weeks after the start of intervention; 1, 3, 6 months and 1 year after the end of intervention ] [ Designated as safety issue: Yes ]
    Depending on the protocol, the end of the intervention corresponds to the end of week 1, 4, 5 or 20 (first day of rTMS as reference)

  • Auditory status, evaluated through tonal audiometry (pure-tone average) [ Time Frame: At subject enrollment; before the first rTMS session and after the last rTMS session (for all types of protocols), and every five sessions of rTMS (for long protocols) ] [ Designated as safety issue: Yes ]
    The time between enrollment and rTMS intervention will vary from one subject to another (expected average of 4 months)

  • Change in severity of tinnitus, measured through a multidimensional self-questionnaire: Subjective Tinnitus Severity Scale (STSS) [ Time Frame: At subject enrollment; before the first rTMS session, in the middle and at the end of intervention period; 1, 4 or 5, and 20 weeks after the start of intervention; 1, 3, 6 months and 1 year after the end of intervention ] [ Designated as safety issue: No ]
    Depending on the protocol, middle (respectively, end) of the intervention corresponds to day 3, day 12, beginning of week 3 or beginning of week 11 (respectively, end of week 1, 4, 5 or 20), with the first day of rTMS as reference

  • Change in handicap related to tinnitus, measured through a multidimensional self-questionnaire: Tinnitus Handicap Questionnaire (THQ) [ Time Frame: At subject enrollment; at the beginning, in the middle and at the end of rTMS intervention period; 1, 4 or 5, and 20 weeks after the start of intervention; 1, 3, 6 months and 1 year after the end of intervention ] [ Designated as safety issue: No ]
  • Change in hyperacusis, measured through a multidimensional self-questionnaire: Auditory Hypersensitivity Questionnaire [ Time Frame: At subject enrollment; at the beginning, in the middle and at the end of rTMS intervention period; 1, 4 or 5, and 20 weeks after the start of intervention; 1, 3, 6 months and 1 year after the end of intervention ] [ Designated as safety issue: No ]
  • Change in anxiety and depression, measured through a two-dimensional self-questionnaire: Hospital Anxiety and Depression Scale (HADS) [ Time Frame: At subject enrollment; at the beginning, in the middle and at the end of rTMS intervention period; 1, 4 or 5, and 20 weeks after the start of intervention; 1, 3, 6 months and 1 year after the end of intervention ] [ Designated as safety issue: No ]
  • Personality, assessed through a multidimensional self-questionnaire: Mini-Mult (short form of the MMPI) [ Time Frame: At subject enrollment ] [ Designated as safety issue: No ]
    The time between enrollment and rTMS intervention will vary from one subject to another (expected average of 4 months)

  • Change in tinnitus spectrum (loudness and pitch), characterized through psychoacoustical measurements: tinnitometry [ Time Frame: At subject enrollment; at the beginning, in the middle and at the end of rTMS intervention period; 1, 4 or 5, and 20 weeks after the start of intervention; 1, 3, 6 months and 1 year after the end of intervention ] [ Designated as safety issue: No ]
  • Motivation level, assessed through a short self-questionnaire (Likert-type scale) [ Time Frame: At the beginning of intervention period (before the first rTMS session) (day 1) ] [ Designated as safety issue: No ]
  • Satisfaction degree, assessed through a short self-questionnaire (Likert-type scale) Time Frame: At the end of SMTr intervention [ Time Frame: At the end of intervention period (end of week 1, 4, 5 or 20, with the first day of rTMS as reference) ] [ Designated as safety issue: No ]

Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Active rTMS

48 subjects will receive active temporal rTMS, applied with the following combined parameters:

  • intensity: 100% of resting motor threshold
  • stimulation frequency: low-frequency continuous stimulation (0.5 or 1 Hz) or high-frequency stimulation trains (4 or 12 Hz)
  • number of stimulations per session: 300, 900 or 1800 per session
  • number of sessions per week: spaced out / low density protocol (1 per week) or dense / high density protocol (5 per week)
  • total number of sessions for the whole intervention: short protocol (5 sessions) or long protocol (20 sessions).
 Device: transcranial magnetic stimulator (class 2b) Medtronic © MagPro X100 (with MagOption) stimulator and Butterfly Coil MCF-B65 (figure-8 coil with fluid cooling)
The study is based on a dual procedure consisting of comparisons between active and sham rTMS on the one hand and between four increasing levels of magnetic "pseudo-dose" on the other hand. Each level comprises 16 patients randomly assigned to active rTMS group (12 patients) or sham rTMS group (4 patients). The transition from one level to another is authorized by an independent oversight committee charged with checking the tolerability of rTMS sessions for the tested level. The neuronavigated rTMS use either active or sham figure-eight coil and is centered over the primary auditory cortex contralateral to the perceived predominant side of tinnitus. This target is located through anatomical brain MRI and neuronavigated brain system. According to the stimulation parameters, each rTMS session can last from 5 to 112 minutes and the whole rTMS intervention from 1 to 20 weeks. The follow-up is spread over twelve months.

Sham Comparator: Sham rTMS
16 subjects will receive sham rTMS, applied with the same combination of parameters as active rTMS, except for the number of stimulations per session (300 or 900)

Same sound level as active rTMS, but magnetic field strongly attenuated
