About this study

Official title: Investigation to the Mechanism of the Neuroplastic Modulation in Central Auditory Tract by Electroacupuncture and Its Clinical Therapeutic Implications

Tinnitus is the awareness of sound or noise in the absence of acoustic stimulation. No definite therapeutic strategy of tinnitus has been developed yet. The current theory of tinnitus is the plasticity theory of neurophysiology model. Although acupuncture has its role in tinnitus treatment, its actual role still remains to be elucidated. Acupuncture has been proposed to induce the development of neuroplasticity. The aim of this project is to undergo a comprehensive investigation to the central auditory effect and the therapeutic effects of acupuncture in tinnitus. According the results of the preliminary studies, the objective auditory measurement and subjective tinnitus perception will be analyzed in tinnitus patients before and after acupuncture.

Read the detailed description

Hearing loss is a common sensory deficit in human beings. Besides communication handicaps, hearing loss may associate with niggling tinnitus symptoms. Tinnitus is the awareness of sound or noise in the absence of acoustic stimulation. Tinnitus may cause bothersome problems in cognition, mood, or psychosocial behaviour and constitute a significant portion in the outpatient clinics of ENT practice. No definite therapeutic strategy of tinnitus has been developed yet. The current theory of tinnitus is the plasticity theory of neurophysiology model. According to this theory, several neuromodulation methods have been proposed such as repetitive transcranial magnetic stimulation (rTMS) or vagus nerve stimulation (VNS). Although acupuncture has its role in tinnitus treatment, its actual role still remains to be elucidated. Acupuncture has been proposed to induce the development of neuroplasticity. There are still few thorough researches to investigate the neurophysiological events after acupuncture. The aim of this project is to undergo a comprehensive investigation to the central auditory effect and the therapeutic effects of acupuncture in tinnitus. According the results of the preliminary studies, the objective auditory measurement and subjective tinn itus perception will be analyzed in tinnitus patients before and after acupuncture. The ultimate results of this project will clarify the basic central auditory effects of acupuncture and provide a potential for translational application of acupuncture to treat the common tinnitus patients.

Questions about this trial

What is this clinical trial studying?

An observational study of Tinnitus and Neuromodulation, run by China Medical University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Auditory brainstem response Wave I, III and V latency (time frame: Day 0). The study lists 24 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Oct 2022.
