  Purpose
Transcranial magnetic stimulation (TMS) is already broadly used in different areas of neuroscience research. Last year, special attention was drawn to TMS in tinnitus. The aim of the researchers' study is to investigate the stimulation characteristics of TMS in tinnitus patients, in particularly the effect of tonic and burst stimulation of the superior temporal lobe.

Condition Intervention
Tinnitus Procedure: TMS transcranial magnetic stimulation

Primary Outcome Measures:
  • VAS visual analogue scale [ Time Frame: immediately before and immediately after single session TMS ]

Enrollment: 64
Study Start Date: January 2007
Study Completion Date: April 2008
Primary Completion Date: September 2007 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Tinnitus
Tinnitus patients
Procedure: TMS transcranial magnetic stimulation

200 pulses of tonic TMS (see Graph 1) were administered with an intensity at 50% of the maximal TMS device output (50%DO).

The frequency of the tonic pulses was randomly chosen between 1Hz, 5Hz, 10Hz or 20Hz.

Burst stimulation was delivered at a burst frequency of 5, 10 or 20Hz. Each burst consisted of 3, 5 or 10 pulses. The individual pulse rate within a burst was 50 or 100Hz.
