Clinical biofeedback is widely used to treat large variety of conditions ranging from migraines to paralysis, to disability associated with stroke. It involves using specific biofeedback instruments which detect physical and chemical signals in the body. By understanding the processes in your body in real time, it is proposed that you can self-regulate your emotional and physical problems which lead to these stress signals.

For example, the GSR2 is a biofeedback device which detects stress levels by monitoring electrical conductivity in the skin and emitting a pitched tone when it senses this physiological marker of stress. By being aware of small changes to which you are normally oblivious, you can self-promote relaxation and prevent the onset of stress. Also available is Camlink software which provides graphical readouts of the GSR2 on your computer.  The price of one of these devices is around $190 [[i]][[ii]].   

There is a wide range of biofeedback devices, each measuring a different bodily signal of stress. The two most popular devices detect temperature and skin conductance.

A recent study was conducted on 130 tinnitus sufferers who received 12 sessions of a biofeedback-based behavioral therapy. Results showed a clear reduction in tinnitus annoyance and tinnitus loudness and improvement in overall control of the condition. In addition, there was a decrease in depressive symptoms. The same findings were maintained 6 months after follow-up suggesting long-term improvement in tinnitus management. 

The same research group has repeated this study with similarly positive results. However, it must be added that in both trials biofeedback was used in combination with CBT, so it is impossible to determine which was the most effective in tinnitus reduction. Nevertheless, it can be assumed that the combined therapy works quite well [[iii]][[iv]].
