Tinnitus can be disabling

Yet another study on tinnitus and the autonomic nervous system as measured with HRV. In this study, no acupuncture is performed, they are just getting HRV profiles of tinnitus sufferers versus normals.  It compares patients with acute and chronic tinnitus to a control population.  They measured HRV for 5 minutes in the subjects.  They found that in chronic tinnitus, the LF/HF ratio was elevated, indicating increased stress or vagal suppression.  Anecdotally, I have been (successfully) treating a patient who had severe tinnitus and anxiety as a result.  I was unaware of the disabling potential of tinnitus.

Abstract

Tinnitus patients suffer from not only auditory sensations but also physical, mental, and social difficulties. Even  though tinnitus is believed to be associated with the autonomic nervous system, changes in autonomic conditions in  tinnitus patients are not receiving much research attention. The aims of this study were to investigate the autonomic  condition of tinnitus patients and to consider Korean medicine in the treatment of tinnitus with an evidence-based  approach. We performed a retrospective chart review and compared the heart rate variability (HRV) parameters of 40  tinnitus patients (19 acute and 21 chronic) and 40 healthy controls. In tinnitus patients, the power of the high  frequency component and total power of the HRV significantly decreased (P < 0.05), and the low frequency to high  frequency ratio significantly increased (P < 0.05). There was no significant difference between the acute and chronic  patients. When comparing each group with the controls, there was a tendency that the longer the duration of tinnitus was,  the larger the observed HRV change was. In conclusion, tinnitus patients have vagal withdrawal and sympathetic  overactivity, and chronic tinnitus more strongly affects autonomic conditions than acute tinnitus. This study provides  evidence for Korean medical treatments of tinnitus, such as acupuncture and Qi-training, that cause modulation of cardiac  autonomic function.

Abstract

Tinnitus patients suffer from not only auditory sensations but also physical, mental, and social difficulties. Even

though tinnitus is believed to be associated with the autonomic nervous system, changes in autonomic conditions in

tinnitus patients are not receiving much research attention. The aims of this study were to investigate the autonomic

condition of tinnitus patients and to consider Korean medicine in the treatment of tinnitus with an evidence-based

approach. We performed a retrospective chart review and compared the heart rate variability (HRV) parameters of 40

tinnitus patients (19 acute and 21 chronic) and 40 healthy controls. In tinnitus patients, the power of the high

frequency component and total power of the HRV significantly decreased (P < 0.05), and the low frequency to high

frequency ratio significantly increased (P < 0.05). There was no significant difference between the acute and chronic

patients. When comparing each group with the controls, there was a tendency that the longer the duration of tinnitus was,

the larger the observed HRV change was. In conclusion, tinnitus patients have vagal withdrawal and sympathetic

overactivity, and chronic tinnitus more strongly affects autonomic conditions than acute tinnitus. This study provides

evidence for Korean medical treatments of tinnitus, such as acupuncture and Qi-training, that cause modulation of cardiac

autonomic function.
