Hearing Beyond the Normal Enabled by Therapeutic Devices: The Role of the Recipient and the Hearing Profession

The future of sensory substitution, addition, and expansion via haptic devices

Haptic devices use the sense of touch to transmit information to the nervous system. As an example, a sound-to-touch device processes auditory information and sends it to the brain via patterns of vibration on the skin for people who have lost hearing. We here summarize the current directions of such research and draw upon examples in industry and academia. Such devices can be used for sensory substitution (replacing a lost sense, such as hearing or vision), sensory expansion (widening an existing sensory experience, such as detecting electromagnetic radiation outside the visible light spectrum), and sensory addition (providing a novel sense, such as magnetoreception). We review the relevant literature, the current status, and possible directions for the future of sensory manipulation using non-invasive haptic devices.

Influencing discussions and use of Neuroadvancements: Perspectives of Canadian occupational therapists

BACKGROUND: The early involvement of many actors including health professionals is identified in neuroethics and neurogovernance discussions as crucial in constructing conversations around awareness, reaction, and knowledge development pertaining to the ethical, legal, and societal consequences of neuroscientific or neurotechnological advancements (NA). Occupational Therapists (OTs) have a stake in NA; however, OTs are rarely mentioned within this context. Lifelong learning (LL) could be used to increase OTs knowledge on NA and its consequences. However, LL is rarely mentioned within neuroethics and neurogovernance discussions. OBJECTIVE: The study’s purpose is to understand the role of OTs as professionals and citizens in neuroethics and neurogovernance discussions and to examine the utility of LL processes put in place for OTs to empower OTs to contribute in a meaningful way to NA discussions. METHODS: 8 semi-structured interviews with OTs were conducted and analyzed using a directed content analysis. RESULTS: Although participants believed OTs can provide a holistic perspective to neurogovernance discussions, their knowledge on NA and its consequences is limited, and LL is not used as a tool to remain informed about such consequences. CONCLUSION: More education on NA and its consequences throughout their OT degree and through LL opportunities is warranted to facilitate their involvement.

Ethical implications of visual neuroprostheses-a systematic review

Objective. The aim of this review was to systematically identify the ethical implications of visual neuroprostheses.Approach. A systematic search was performed in both PubMed and Embase using a search string that combined synonyms for visual neuroprostheses, brain-computer interfaces (BCIs), cochlear implants (CIs), and ethics. We chose to include literature on BCIs and CIs, because of their ethically relavant similarities and functional parallels with visual neuroprostheses.Main results. We included 84 articles in total. Six focused specifically on visual prostheses. The other articles focused more broadly on neurotechnologies, on BCIs or CIs. We identified 169 ethical implications that have been categorized under seven main themes: (a) benefits for health and well-being; (b) harm and risk; (c) autonomy; (d) societal effects; (e) clinical research; (f) regulation and governance; and (g) involvement of experts, patients and the public.Significance. The development and clinical use of visual neuroprostheses is accompanied by ethical issues that should be considered early in the technological development process. Though there is ample literature on the ethical implications of other types of neuroprostheses, such as motor neuroprostheses and CIs, there is a significant gap in the literature regarding the ethical implications of visual neuroprostheses. Our findings can serve as a starting point for further research and normative analysis.

Influencing discussions and use of neuroadvancements as professionals and citizens: Perspectives of Canadian speech-language pathologists and audiologists

BACKGROUND: Early involvement of stakeholders in neuroethics and neurogovernance discourses of neuroscientific and neurotechnological advancements is seen as essential to curtail negative consequences. Speech-language pathologists (SLPs) and audiologists (AUs) make use of neuroadvancements including cochlear implants, brain-computer interfaces, and deep-brain stimulation. Although they have a stake in neuroethics and neurogovernance discussions, they are rarely mentioned in having a role, whether as professionals or as citizens. OBJECTIVE: The objective of the study was to explore the role of SLPs and AUs as professionals and citizens in neuroethics and neurogovernance discussions and examine the utility of lifelong learning mechanisms to learn about the implications of neuroadvancements to contribute in a meaningful way to these discussions. METHODS: Semi-structured interviews conducted with 7 SLPs and 3 AUs were analyzed using thematic analysis. RESULTS: Participants stated that their roles expected from them as professionals and as citizens indicate the importance to be knowledgeable on ethical, legal, and social implications of neuroadvancements and that lifelong learning is not used to learn about these implications. CONCLUSION: More must be done to facilitate the participation of SLPs and AUs in neuroethics and neurogovernance discussions, which would enrich the neuroethics and neurogovernance discourses benefitting patients, professionals, and the public.

Impact of robotics and human enhancement on occupation: what does it mean for rehabilitation?

Purpose: People with disabilities face participation challenges in all occupations. Scientific and technological advancements impact the occupational landscape of humans. This scoping review aimed to ascertain the academic engagement with occupation in relation to robotics and human enhancement focusing in particular on how people with disabilities and rehabilitation were mentioned.Method: SCOPUS and the 70 databases of EBSCO host were searched. Manifest and latent content coding and thematic grouping of codes relevant to answering the review questions was performed.Results: Only four articles engaged with occupation in relation to human enhancement. As to occupation and robotics, some occupational fields were visible and not others; occupational health and safety was the most visible one; people with disabilities were covered from a medical, therapeutic angle and not in relation to social issues caused by the occupational impact of robotics. Change in the scope, meaning, and clients of rehabilitation efforts related to occupation enabled by human enhancement and robotics was not covered.Conclusions: The gaps found should be filled. The impact of robotics and human enhancement on the occupational landscape indicates the need for rehabilitation to think beyond recovery to the species typical as a goal. The ultrabilitation concept could help to meet this need.Implications for rehabilitationAdvances in robotics and human enhancement beyond species-typical levels modify the occupational landscape, human ability expectations in this setting, and the meaning and scope of disability and rehabilitation (clinical and community based).There is a need to elucidate the impact of these changes on the meaning, scope and goals of recovery-oriented rehabilitation.The recently coined term "ultrabilitation" creates space to discuss an ability expectation creep triggered by developments in robotics and human enhancement, particularly within occupation focused rehabilitation.

Neuroethics beyond Normal

An integrated and principled neuroethics offers ethical guidelines able to transcend conventional and medical reliance on normality standards. Elsewhere we have proposed four principles for wise guidance on human transformations. Principles like these are already urgently needed, as bio- and cyberenhancements are rapidly emerging. Context matters. Neither "treatments" nor "enhancements" are objectively identifiable apart from performance expectations, social contexts, and civic orders. Lessons learned from disability studies about enablement and inclusion suggest a fresh way to categorize modifications to the body and its performance. The term "enhancement" should be broken apart to permit recognition of enablements and augmentations, and kinds of radical augmentation for specialized performance. Augmentations affecting the self, self-worth, and self-identity of persons require heightened ethical scrutiny. Reversibility becomes the core problem, not the easy answer, as augmented persons may not cooperate with either decommissioning or displacement into unaccommodating societies. We conclude by indicating how our four principles of self-creativity, nonobsolescence, empowerment, and citizenship establish a neuroethics beyond normal that is better prepared for a future in which humans and their societies are going so far beyond normal.

Cochlear Implantation, Enhancements, Transhumanism and Posthumanism: Some Human Questions

Biomedical engineering technologies such as brain-machine interfaces and neuroprosthetics are advancements which assist human beings in varied ways. There are exciting yet speculative visions of how the neurosciences and bioengineering may influence human nature. However, these could be preparing a possible pathway towards an enhanced and even posthuman future. This article seeks to investigate several ethical themes and wider questions of enhancement, transhumanism and posthumanism. Four themes of interest are: autonomy, identity, futures, and community. Three larger questions can be asked: will everyone be enhanced? Will we be "human" if we are not, one day, transhuman? Should we be enhanced or not? The article proceeds by concentrating on a widespread and sometimes controversial application: the cochlear implant, an auditory prosthesis implanted into Deaf patients. Cochlear implantation and its reception in both the deaf and hearing communities have a distinctive moral discourse, which can offer surprising insights. The paper begins with several points about the enhancement of human beings, transhumanism's reach beyond the human, and posthuman aspirations. Next it focuses on cochlear implants on two sides. Firstly, a shorter consideration of what technologies may do to humans in a transhumanist world. Secondly, a deeper analysis of cochlear implantation's unique socio-political movement, its ethical explanations and cultural experiences linked with pediatric cochlear implantation-and how those wary of being thrust towards posthumanism could marshal such ideas by analogy. As transhumanism approaches, the issues and questions merit continuing intense analysis.

Cognitive Enhancement: Perceptions Among Parents of Children with Disabilities

Cognitive enhancement is an increasingly discussed topic and policy suggestions have been put forward. We present here empirical data of views of parents of children with and without cognitive disabilities. Analysis of the interviews revealed six primary overarching themes: meanings of health and treatment; the role of medicine; harm; the ‘good’ parent; normality and self-perception; and ability. Interestingly none of the parents used the term ethics and only one parent used the term moral twice.

Emerging Therapeutic Enhancement Enabling Health Technologies and Their Discourses: What Is Discussed within the Health Domain?

So far, the very meaning of health and therefore, treatment and rehabilitation is benchmarked to the normal or species-typical body. We expect certain abilities in members of a species; we expect humans to walk but not to fly, but a bird we expect to fly. However, increasingly therapeutic interventions have the potential to give recipients beyond species-typical body related abilities (therapeutic enhancements, TE). We believe that the perfect storm of TE, the shift in ability expectations toward beyond species-typical body abilities, and the increasing desire of health consumers to shape the health system will increasingly influence various aspects of health care practice, policy, and scholarship. We employed qualitative and quantitative methods to investigate among others how human enhancement, neuro/cognitive enhancement, brain machine interfaces, and social robot discourses cover (a) healthcare, healthcare policy, and healthcare ethics, (b) disability and (c) health consumers and how visible various assessment fields are within Neuro/Cogno/Human enhancement and within the BMI and social robotics discourse. We found that health care, as such, is little discussed, as are health care policy and ethics; that the term consumers (but not health consumers) is used; that technology, impact and needs assessment is absent; and that the imagery of disabled people is primarily a medical one. We submit that now, at this early stage, is the time to gain a good understanding of what drives the push for the enhancement agenda and enhancement-enabling devices, and the dynamics around acceptance and diffusion of therapeutic enhancements.
