“…The U.S. Department of Health and Human Services, as indicated in Healthy People 2020, included timely hearing screening with appropriate treatment referral as a priority achievement 1 . The high prevalence of hearing loss has been reported in the literature as well, with over 30 million people age 12 and over experiencing some degree of hearing loss in both ears 2–4 . As the life expectancy in the U.S. continues to climb, the health burden of chronic disease would be expected to increase substantially, making prompt recognition and intervention essential.…”

“…Sensorineural hearing loss is primarily treated with hearing aids; however, when the degree of loss becomes severe cochlear implantation is the standard of care. In spite of highly rated hearing-related outcomes and quality of life for cochlear implant (CI) patients, 4 this aspect of hearing healthcare is not widely accessed by those who may benefit. Despite an abundance of data to support their efficacy and FDA approval in the United States for 30 years, it is estimated that fewer than 6% of Americans who could benefit from CI have one 5 .…”

Objective-The purpose of this study is to compare the timing and impact of hearing healthcare of rural and urban adults with severe hearing loss who use cochlear implants (CI).Study Design-Cross-sectional questionnaire study Setting-Tertiary referral center Patients-Adult cochlear implant recipients.Main Outcome Measures-Data collected included county of residence, socioeconomic information, impact of hearing loss on education/employment, and timing of hearing loss treatment. The benefits obtained from cochlear implantation were also evaluated.

Objective The purpose of this study was to assess the feasibility and effectiveness of live telemedicine applications in hearing amplification and cochlear implantation. Data Sources and Study Selection A systematic search was performed in PubMed, MEDLINE, PsychINFO, CINALH, and Web of Science to identify peer-reviewed research. Inclusion criteria were titles containing words from the search terms (1) audiology, otolaryngology, and hearing impairment, (2) rehabilitative methods, and (3) telemedicine. Exclusion criteria were 1) non-English articles, and 2) non-original research. Data Extraction and Synthesis Twelve eligible studies were identified. The studies employed a prospective design in nine of the articles and retrospective case series in three. The use of telemedicine for the provision of cochlear implant services was examined in eight of the articles and with hearing aids in four of the articles. The types of services include intraoperative cochlear implant telemetry; implant programming and assessment of electrode-specific measures and speech recognition after implantation. Hearing aid programming and remote gain assessments were also reported. Many studies assess patient and provider satisfaction along with encounter time comparison. The studies occurred from 2009–2014 and took place in seven countries. Conclusions This review examined the feasibility of remote telemedicine connection to provide in auditory rehabilitation services through hearing aids and cochlear implants. There are significant concerns regarding Internet bandwidth limitations for remote clinics. There is a paucity of research examining reimbursement and cost-effectiveness for services. Further prospective research investigating cost-effectiveness and bandwidth limitations is warranted to assess long-term sustainability of remote audiological rehabilitative service delivery.

“…This drastically reduces the amount of information that can be extracted from a perceived sound (16,000 channels of information are reduced to 8 channels). Despite this limitation, the cochlear implant remains amongst the most successful neural stimulation systems and can restore speech perception in most subjects [124].…”

This chapter explores the variability and limitations of traditional stimulation electrodes by first appreciating how electrical potential differences lead to efficacious activation of nearby neurons and examining the basic electrochemical mechanisms of charge transfer at an electrode/electrolyte interface. It then covers the advantages and current challenges of emerging micro-/nanostructured electrode materials for next-generation neural stimulation microelectrodes. Introduction to Electrical Stimulation of NeuronsStimulation electrodes have many clinical applications. The most common clinically approved stimulator is the artificial cardiac pacemaker, which is implanted into patients with a slow or arrhythmic heartbeat [1]. Artificial pacemakers use electrodes placed directly in contact with the heart muscles to regulate heart rate by delivering a timed series of electrical pulses. Another common stimulation device implanted into many adults and children is the cochlear implant [2]. Cochlear duct electrodes are designed as a series of stimulation contacts arranged along a flexible silicone carrier (Fig. 4.1a). These electrodes are placed into the cochlea where they directly electrically stimulate nerve cells, bypassing damaged hair cells that transduce acoustic vibrations into electrical impulses in the underlying nerve cells. (Fig. 4.1b). Electrical stimulation in these deep brain structures, such as the basal ganglia, has been used to treat symptoms of Parkinson's disease including tremor and bradykinesia, as well as other movement disorders such as dystonia [3][4][5]. In addition, DBS is being studied as a treatment for stroke, chronic pain, major depression, and chronic obesity [6-10]. For epilepsy and major depression, vagal nerve stimulation offers an alternative that does not require brain surgery [11,12]. In the extremities, functional electrical stimulation (FES) is used to deliver electrical current to activate nerves or muscles in disabled patients. FES has been applied to aid in standing, walking, and basic handgrips and for restoring bowel and bladder function [13][14][15]. Many other electrical stimulation applications exist, including the restoration of somatosensation and vision, the treatment of hypertension and gastroparesis, and the promotion of nerve regeneration [16][17][18][19].While these neurostimulation devices have demonstrated some success in bypassing, replacing, or treating damaged neural circuits, they are far from being able to reliably restore natural function in all patients. In order to understand the variability and limitations of traditional stimulation electrodes, we must first appreciate how electrical potential differences lead to efficacious activation of nearby neurons and examine the basic electrochemical mechanisms of charge transfer at an electrode/electrolyte interface. This chapter will first lay out our current knowledge of these areas and afterwards will cover the advantages and current challenges of emerging micro-/nanostructured electrode materials for ...
