Trial summary

The goal of this observational study is to learn about the sound-induced vibration level of certain structures in the middle ear in the normal-hearing population. The targeted structures are part of a chain of structures responsible for conducting sound within the auditory system and so their ability to vibrate… Read more about this study

About this study

The goal of this observational study is to learn about the sound-induced vibration level of certain structures in the middle ear in the normal-hearing population. The targeted structures are part of a chain of structures responsible for conducting sound within the auditory system and so their ability to vibrate normally in response to sound is relevant to the diagnosis of conductive hearing loss.

The main questions the study aims to answer are:

Read more
  • What are the mean and variance of the normal sound-induced vibration level at two anatomical locations, the umbo of the malleus and the tip of the incus?
  • Are there any significant differences in these vibrational responses associated with sex or age?

Participants will have their ossicular mobility measured with an investigational medical device that sends light into the middle ear and measures the motion-induced phase shift on light reflected from the target structures when a sound stimulus is presented. Standard hearing tests including audiometry and tympanometry will also be performed to confirm the normal hearing status of participants.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ossicular mobility measurementDiagnostic test

    Measurements of ossicular mobility i.e. the dynamic velocity of middle ear structures (umbo of malleus and incus at the incudostapedial joint) normalized to sound pressure incident on the tympanic membrane.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Umbo mobility

    Estimated mean and variance of mobility in mm/s/Pa in the normal-hearing population measured at the umbo of the malleus at 500Hz, 750Hz, 1000Hz, 1500Hz, 2000Hz and 3000Hz stimulus frequencies.

    Measured: At study completion (6 months)

  2. Incus mobility

    Estimated mean and variance of mobility in mm/s/Pa in the normal-hearing population measured at the incus lateral to the incudostapedial joint at 500Hz, 750Hz, 1000Hz, 1500Hz, 2000Hz and 3000Hz stimulus frequencies.

    Measured: At study completion (6 months)

Secondary outcomes (1)
  1. Dependence on age and sex

    p-values for dependence on age, sex and age-sex interaction at each stimulus frequency within two-way ANOVA.

    Measured: At study completion (6 months)

Questions about this trial

What is this clinical trial studying?

An observational study of Conductive Hearing Loss, Middle Ear, run by Audioptics Medical Incorporated at 1 site in Canada.

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 4 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 1 Aug 2024. 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 Canada. 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?

Results are not available in the source record.

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

Contact Robert Adamson, PhD (902-497-8579, rob.adamson@audiopticsmedical.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Umbo mobility (time frame: At study completion (6 months)). The study lists 2 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 1 Aug 2024.
