2017 RESEARCH WITH

THE PARASYM (SALUSTIM) IN TINNITUS PATIENTS 

 

The Tinnitus Treatment Centre provide neuromodulation for tinnitus relief.

 

A January 2017 publication used the Parasym (SaluStim) treating 97 Tinnitus patients with a short course of tVNS. The study concludes ‘Transcutaneous vagal nerve stimulation (tVNS) can offer a targeted, patient-friendly, and low-cost therapeutic tool for tinnitus patients with sympathovagal imbalance.’

 

The study focused on measuring heart rate variability (HRV). All patients had been diagnosed with moderate-to-severe tinnitus defined by a Tinnitus Handicap Inventory Questionnaire (THI) score >32 and mini tinnitus questionnaire. Patients were monitored before, after and during their tVNS treatment.

 

Results showed an increase in HRV in most patients. There were no associated risks reported. ‘The pre-treatment HRV recording showed sympathetic preponderance/reduced parasympathetic activity in about three quarters (73%) of patients. Active tVNS significantly increased variability of R-R intervals in 75% of patients and HRV age was decreased in 70% of patients. Either the variability of R-R intervals was increased or the HRV age decreased in 90% of the patients.

 

These results indicate that tVNS can induce a shift in ANS function from sympathetic preponderance towards parasympathetic predominance. tVNS caused no major morbidity, and heart rate monitoring during the tVNS treatment showed no cardiac or circulatory effects (e.g. bradycardia) in any of the patients.’
