About this study

Official title: Evaluation of the Central Auditory Processing in Patients (Elder Than 45 Years Old) With Bilateral Sensorineural Hearing Loss and the Change of the Central Auditory Processing Ability by the Use of Hearing Aids (CAPHA)

The purpose of this study is to evaluate the central auditory processing in patients with bilateral sensorineural hearing loss and to observe the change of the central auditory processing ability after using hearing aids.

Read the detailed description

Screening for recruiting

  • Among patients who are visiting for hearing disturbance, patients with bilateral sensorineural hearing loss will be included after audiologic tests, history taking and physical examination.
  • audiologic tests: pure tone audiometry, speech audiometry, impedence audiometry, distortion product otoacoustic emission, auditory brainstem response.

Dividing into "Hearing aids" group and "No hearing aids" group

  • The use of hearing aids will be recommended to all included patients.
  • Hearing aids group: patients who want to be prescribed hearing aids (28 subjects)
  • No hearing aids group: patients who do not want to be prescribed hearing aids (28 subjects)

Audiologic test

  • Hearing in noise test (HINT), central auditory processing disorder test
  • at screening, 1, 3, 6, 9 and 12 months after starting hearing aids use

What is being measured

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

  1. Change from the baseline in the Hearing In Noise Test (HINT) score at 6 months

    HINT measures a person's ability to hear speech in quiet and in noise. In the test, the patient is required to repeat sentences both in a quiet environment and with competing noise being presented from different directions.

    Measured: at screening and 6 months after starting hearing aids use

Secondary outcomes (2)
  1. changes from the baseline in central auditory processing disorder test score at 1, 3, 6, 9 and 12 months

    The central auditory processing disorder test is composed of three subtests; duration pattern test, frequency pattern test and dichotic words test. The patient is required to discriminate long duration sound from short one and high frequency sound from low one, and to repeat two words that are given simultaneously.

    Measured: at screening, 1, 3, 6, 9, and 12 months after starting hearing aids use

  2. changes from the baseline in the HINT score at 3, 9, and 12 months

    Measured: baseline, 3, 9 and 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Hearing aids in people with Auditory Processing Disorder, Central, run by Jong Woo Chung at 1 site in South Korea.

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 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 17 Feb 2016. 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 South Korea. 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?

Change from the baseline in the Hearing In Noise Test (HINT) score at 6 months (time frame: at screening and 6 months after starting hearing aids use). 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 17 Feb 2016.
