Clinical Trial Summary

This is a three arm, patient subtyping and parameter optimisation study for a neuromodulation treatment for tinnitus.

Description:

Participants with chronic tinnitus will be provided with a CE marked neuromodulation device. Devices will be programmed with one of 3 stimulation parameter settings. After 12 weeks of use, differences in tinnitus severity scores will be compared between the 3 arms and within the arms for patient subtype analysis.

• Neurological conditions that may lead to loss of consciousness (e.g. epilepsy) or is considered to be the dominant feature of the tinnitus, as assessed by audiologist or ENT consultant

• Severe cognitive impairment based on Mini Mental State Examination (MMSE), less than 20

• Pacemakers or other electro-active implanted devices

• Have used Neuromod Devices products in the past

• Participants currently prescribed drugs for a Central Nervous System pathology, i.e. epilepsy, Multiple Sclerosis (MS), Parkinson's, bi-polar disorder.

• The site Principal Investigator does not deem the candidate to be suitable for the study for other reasons not listed above

• Self-reporting episodes of Auditory hallucinations

• Abnormal Otoscopy as assessed by the Audiologist, including active Otitis Media, perforation and hearing loss that is identified as completely conductive

Intervention

Device:
• PS1
Participants in this arm shall be given an audio stimulus which comprises of a sequence of tones, mixed with a broadband noise that is spectrally modified to compensate for any hearing loss. Electrical pulses in the somatosensory stimulation are synchronous with the tones.
• PS2
Participants in this arm shall be given an audio stimulus which comprises of a sequence of tones, mixed with a broadband noise that is spectrally modified to compensate for any hearing loss. Electrical pulses in the somatosensory stimulation are uncorrelated and asynchronous with the tones.
• PS3
Participants in this arm shall be given an audio stimulus which comprises of a sequence of single-frequency tones mixed with a broadband noise with the frequency characteristics of both chosen outside the region of any hearing loss. Electrical pulses in the somatosensory stimulation are uncorrelated and asynchronous with the tones.
