Study type | Interventional |
The purpose of this study is to develop and validate methods to use hearing aids equipped with embedded sensors and artificial intelligence to assist in the assessment of fall risk and in the implementation of interventions aimed at reducing the risk of falling, as well as to improve speech intelligibility in quiet and in background noise, track physical activity, and social engagement. The investigators hope is that the knowledge that is generated through this study will ultimately translate to the clinical setting and will help reduce the likelihood that individuals experience a fall, and improve the quality of hearing in individuals who wear hearing aids.

Eligibility | Inclusion Criteria: - Age 55 years or older - Bilateral hearing aid user - Able to consent in English - Having access to a phone capable of running the mobile app required for the study - Screen for fall risk ("Yes" to any question: Feels unsteady when standing or walking? Worries about falling? Has fallen in past year? If the participant has fallen: how many times? were they injured/hurt?) - Ambulatory without need for a wheelchair Exclusion Criteria: - People with mobility restrictions (e.g., wheelchair bound) that would prevent the performance of the functional assessments. - People with severe movement (e.g., Advanced Parkinson's disease) or cognitive (e.g., advanced dementia) disorders that would prevent the individual from either performing the functional assessments, or would lead to restricted activities that would prevent motion data from being collected according to the goal of the study. - Inability to understand, consent, and complete requirements including verbal instructions and non-ambulatory/wheelchair-dependent. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Fall risk assessment using CDC's STEADI protocol | Participants will undergo the Centers for Disease Control and Prevention (CDC)'s STEADI (Stopping Elderly Accidents, Deaths & Injuries) fall risk assessment with the hearing aids on. The scoring for these tests will be done by the tester, 2 independent raters, and the hearing aids. A comparison of the fall risk assessments by the testers and the hearing aids is the primary outcome measure. This outcome is assessed in Fall Risk Assessment participants only. | approximately 15 minutes to assess on day 1 | |
Primary | Timed Up and Go Test | Duration of time to stand, walk to a line on the floor (3 meters/10 feet away), turn around, return to chair and sit. Participants wear their regular footwear and can use a walking aid if needed. This outcome is assessed in Fall Risk Assessment participants only. | approximately 15 minutes to assess on day 1 | |
Primary | 30-Second Chair Stand Test | Number of times participants can stand without using their arms during the test. Participants wear their regular footwear and can use a walking aid if needed. This outcome is assessed in Fall Risk Assessment participants only. | approximately 15 minutes to assess on day 1 | |
Primary | 4-Stage Balance Test | Participants who are able to keep their balance for 10 second in each of four positions (feet together, feet staggered, feet in tandem, and single foot stand). They can hold their arms out, or move their body to help keep your balance, but not move their feet. This outcome is assessed in Fall Risk Assessment participants only. | approximately 15 minutes to assess on day 1 | |
Primary | Consonant-Nucleus-Consonant (CNC) | The number and percentage of words and phonemes accurately repeated are measured in aided (using hearing aids) and unaided conditions. This outcome is measured in Speech Intelligibility participants only. | Approximately 10-15 minutes. | |
Primary | Quick Speech-in-Noise (QuickSIN) | The number and percentage of words and phonemes accurately repeated are measured in ambient noise conditions in aided and unaided conditions. This outcome is measured in Speech Intelligibility participants only. | Approximately 10-15 minutes. | |
Primary | Words-in-Noise (WIN) | The number and percentage of words and phonemes accurately repeated are measured in muli-talker babble noise conditions in aided and unaided conditions. This outcome is measured in Speech Intelligibility participants only. | Approximately 10-15 minutes. | |
Primary | Nonsense Syllable Test (NST) | The number and percentage of words and phonemes accurately repeated are measured in continuous noise conditions in aided and unaided conditions. This outcome is measured in Speech Intelligibility participants only. | Approximately 10-15 minutes. | |
Secondary | Fall risk assessment using CDC's STEADI protocol | Participants will undergo the Centers for Disease Control and Prevention (CDC)'s STEADI (Stopping Elderly Accidents, Deaths & Injuries) fall risk assessment with the hearing aids on. Assessments are conducted remotely with the clinician or using the app. This outcome is assessed longitudinally at time points determined per participant. This outcome is assessed in Fall Risk Assessment participants only. | up to 1 year (up to 1 hour per assessment) | |
Secondary | Listening Effort Questionnaire Scale Score | Listening effort scale score measures the participant's perceived listening effort. This outcome is measured in Speech Intelligibility participants only. | Approximately 5 minutes. | |
Secondary | Auditory Lifestyle and Demand Scale Score | Auditory Lifestyle and Demand scale score measures perceived demands of hearing on lifestyle. This outcome is measured in Speech Intelligibility participants only. | Approximately 5 minutes. | |
Secondary | User Experience Questionnaire | Participants rate their experience with the hearing aid regarding the following aspects: perceived difficulty communicating and listening effort in different environments. | Approximately 2 minutes. |
