PurposeThe purpose of this study was to compare impact loading, kinematic and physiological responses to three different immersion depths (mid-shin, mid-thigh, and xiphoid process) while running at the same speed on a water based treadmill.MethodsParticipants (N=8) ran on a water treadmill at three depths for 3min. Tri-axial accelerometers were used to identify running dynamics plus measures associated with impact loading rates, while heart rate data were logged to indicate physiological demand.ResultsParticipants had greater peak impact accelerations (p<0.01), greater impact loading rates (p<0.0001), greater stride frequency (p<0.05), shorter stride length (p<0.01), and greater rate of acceleration development at toe-off (p<0.0001) for the mid-shin and mid-thigh compared to running immersed to the xiphoid process. Physiological effort determined by heart rate was also significantly less (p<0.0001) when running immersed to the xiphoid process.ConclusionWater immersed treadmill running above the waistline alters kinematics of gait, reduces variables associated with impact, while decreasing physiological demand compared to depths below the waistline.

Interventional Audiology to Address Hearing Health Care Disparities: Oyendo Bien Pilot Study.
Semin Hear. 2017 May;38(2):198-211

Abstract
Interventional audiology, specifically community-based outreach, can connect people with the hearing health care system. Community-based participatory research methods were applied in two phases of research to: (1) investigate the needs of families affected by hearing loss in a rural Arizona community on the U.S.-Mexico border; and (2) evaluate an outreach program on hearing health. The needs assessment included interviews with persons with hearing loss and focus groups with family members and the greater community. The needs assessment revealed that despite perceived severity of hearing loss, help-seeking for audiologic care was limited due to barriers, stigma, and low self-efficacy. Results informed development of a community-based pilot study conducted as part of an academic-community partnership between audiology, public health, and community health workers of a federally qualified health center. An outreach program, Oyendo Bien (hearing wellness), a 5-week, Spanish-language health education program for older adults (n = 21) incorporated communication strategies and behavioral change techniques. Postprogram focus groups revealed increased self-efficacy and decreased stigma. After 1 year, 7 of 9 participants with hearing loss contacted for follow-up had sought some form of hearing-related health care. Future research should further investigate interventional audiology approaches to address health disparities.

HearCARE: Hearing and Communication Assistance for Resident Engagement.
Semin Hear. 2017 May;38(2):184-197

Abstract
Impaired hearing is related to poor health outcomes, including compromised cognitive function, in aging individuals. Hearing loss is the third most common chronic health condition after arthritis and heart disease in older adults and the fourth most detrimental condition related to quality of life in older adults. Only 18% of aging adults who have impactful hearing loss actually use custom-fit amplification. Therefore, the majority of aging individuals entering senior living facilities will have untreated hearing loss. Older adults move to senior communities to maintain or increase their social engagement, to receive care from qualified staff, and to ultimately enhance their quality of life. We know that the majority of individuals over 65 years of age have significant hearing loss, which leaves them with complex listening needs due to low incidence of hearing aid use, group communication situations that are common for social activities, interactive dining environments, and the need for telephone use to connect with loved ones. Busy staff and family members may not be aware of the impact of decreased hearing on quality of life, as well as caregiver burden. HearCARE (Hearing and Communication Assistance for Resident Engagement) is an initiative to provide communication assistance on a day-to-day basis in senior living facilities in a cost-effective manner. This innovative model for delivering audiology services and communication assistance in senior living communities employing communication facilitators who are trained and supervised by an audiologist will be described. Data related to the communication facilitator training, daily activities, interactions with the audiologist, use of devices, and impact on residents, staff, and families will be described.

Enhancing Communication in Adults with Dementia and Age-Related Hearing Loss.
Semin Hear. 2017 May;38(2):177-183

Abstract
For many adults with dementia, age-related hearing loss is undiagnosed and/or untreated. Untreated hearing loss can exacerbate common dementia-related behavioral symptoms, such as depression, apathy, agitation. Despite the potential benefits to the individual and the family, pursuing and adopting hearing aids for persons with dementia presents with many challenges. As such, this group of vulnerable older adults is well suited for alternative approaches that adopt an interventional audiology framework. This article reviews alternative hearing care models that we have tested when working with older adults with cognitive impairments. We have found that some individuals show improvements in dementia-related problem behaviors and/or in measures of social engagement after brief aural rehabilitation interventions that provide non-custom amplification. We have developed simple training materials to help family and professional caregivers use communication strategies and non-custom amplification. Providing services that can be integrated into the person's broader dementia care has the potential to improve communication and quality of life for individuals and families. There are opportunities in this population to provide basic, simple strategies and make substantial improvements as long as we adopt approaches that bring the services to the people, instead of bringing the people to us in the audiology clinic.
