研究概览
简要总结
Tinnitus is a common problem which can have a severe impact on quality of life and for which there is no truly successful treatment available.
Repetitive transcranial magnetic stimulation (rTMS) is a method of stimulating the brain through the application of a magnetic field in a series of rapid pulses and may be a valuable treatment for patients with tinnitus.
The overall aim of this research is to see if patients with tinnitus benefit from treatment with rTMS, and in particular whether one type (continuous theta burst) is more effective than other variations of rTMS. Prior to developing a definitive study to address this area a feasibility study needs to be performed.
The proposed feasibility study aims to determine outcomes necessary to enable development of a definitive study in the future.
40 patients suffering with idiopathic tinnitus will be randomised into 2 groups, a control group receiving a sham treatment, and an active treatment group receiving theta-burst rTMS on 5 consecutive days.
详细描述
Tinnitus is a common problem and can have a severe impact on quality of life. At present there is no truly successful treatment available. Repetitive transcranial magnetic stimulation (rTMS) is a method of stimulating the brain through the application of a magnetic field in a series of rapid pulses. Applying it to the areas of the brain thought to be responsible for tinnitus may offer a valuable treatment for patients.
The overall aim of this research is to see if patients with tinnitus benefit from treatment with rTMS, and in particular whether one type (continuous theta burst) is more effective than other variations of rTMS. Prior to developing a definitive study to address this area a feasibility study needs to be performed.
The proposed feasibility study aims to determine outcomes necessary to enable development of a definitive study in the future. Particularly to ensure adequate recruitment will be possible and to confirm the acceptability of the study design to participants. We will assess the success of our chosen placebo intervention and blinding method. The variance in change in tinnitus level following treatment will enable a sample size calculation to be performed for use in future studies.
40 patients suffering with idiopathic tinnitus will be randomised into 2 groups, a control group receiving a sham treatment, and an active treatment group receiving theta-burst rTMS on 5 consecutive days. The effect of treatment will be assessed through the use of the Tinnitus Functional Index an existing validated tinnitus questionnaire. Feasibility outcomes will be assessed through monitoring retention and recruitment rates and the use of questionnaires related to feasibility outcomes

结局指标
主要结局
Improvement in tinnitus severity following treatment with rTMS
时间窗: 3 months
The primary outcome measure for the definitive trial is the improvement in tinnitus severity following treatment with theta burst rTMS compared to control as demonstrated by change in Tinnitus Functional Index (TFI) scores. Assessed on completion of treatment and at 1 week and 1 month following.
