“…The societal landscape of occupation (paid, unpaid, leisure, daily activity…) and humans as occupational being (1-11) is one area of impact of STI. Recent STI advancements with occupational impact include robotics (3,5,(12)(13)(14)(15)(16)(17)(18), autonomous cars (5,19,20), brain machine interfaces (21), and human enhancement (22)(23)(24)(25). Given the continuous impact of STI on individuals and society it is not surprising that many discourses engage with how to deal with the impact of STI advancements.…”

BACKGROUND: Science, technology and innovation (STI) governance concerns itself with the societal impact of STI. Occupation, whether used with the meaning of paid, unpaid work or any activity that is considered meaningful to the individual on an everyday basis is one area of societal impact of STI. Fields such as occupational therapy, occupational science and occupational health and safety concern themselves with the relationship between occupation and the health and well-being of human beings albeit all with different foci. OBJECTIVE: To ascertain the knowledge of student from two Occupational Therapy programs on STI governance, specific STI products and their views on the impact of STI governance and STI products on occupational therapy and its clients. METHODS: Online survey employing Yes/No' questions with comment boxes and openended textbox questions. Descriptive quantitative and thematic qualitative data was generated RESULTS: Students were unfamiliar with STI governance discourses but felt that they should be aware of them. Students stated that how one governs STI impacts occupational therapy on all levels and that the occupational therapy community has expertise that would enrich STI governance discourses around occupation. CONCLUSION: Education actions seem to be warranted on the level of students and practitioners by the occupational therapy and STI governance communities.

“…For many growing therapeutic BMI applications, such as retraining the brain after stroke or traumatic brain injury, cortical damage is likely to be the norm [12-36]. Even in healthy spinal-cord-injured individuals, the cortical signals are still likely to have changed with disuse over time [69-71].…”

“…Individuals paralyzed due to high-level spinal cord injury, brainstem stroke, and amyotrophic lateral sclerosis have used implanted BMI systems to control various assistive devices using the neural activity associated with their natural thoughts of movement [1-11]. Many research studies are also now investigating the use of BMIs in stroke and traumatic brain injury as a therapeutic tool to encourage beneficial plasticity and enhance motor recovery [12-38]. Given that the estimated number of stroke survivors in the United States has now grown to 7,000,000 [39], BMIs may help fill the significant need for more effective therapies for this growing population.…”

Objective Our goal was to identify spatial filtering methods that would improve decoding of continuous arm movements from epidural field potentials as well as demonstrate the use of the epidural signals in a closed-loop brain-machine interface (BMI) system in monkeys. Approach Eleven spatial filtering options were compared offline using field potentials collected from 64-channel high-density epidural arrays in monkeys. Arrays were placed over arm/hand motor cortex in which intracortical microelectrodes had previously been implanted and removed leaving focal cortical damage but no lasting motor deficits. Spatial filters tested included: no filtering, common average referencing (CAR), principle component analysis (PCA), and eight novel modifications of the common spatial pattern (CSP) algorithm. The spatial filtering method and decoder combination that performed the best offline was then used online where monkeys controlled cursor velocity using continuous wrist position decoded from epidural field potentials in real time. Main results Optimized CSP methods improved continuous wrist position decoding accuracy by 69% over CAR and by 80% compared to no filtering. Kalman decoders performed better than linear regression decoders and benefitted from including more spatially-filtered signals but not from pre-smoothing the calculated power spectra. Conversely, linear regression decoders required fewer spatially-filtered signals and were improved by pre-smoothing the power values. The ‘position-to-velocity’ transformation used during online control enabled the animals to generate smooth closed-loop movement trajectories using the somewhat limited position information available in the epidural signals. The monkeys’ online performance significantly improved across days of closed-loop training. Significance Most published BMI studies that use electrocortographic signals to decode continuous limb movements either use no spatial filtering or CAR. This study suggests a substantial improvement in decoding accuracy could be attained by using our new version of the CSP algorithm that extends the traditional CSP method for use with continuous limb movement data.

“…Given role theory, this role expectation of OTs should shape OTs' own expectations of what roles they are to fill [90]. Stakeholder engagement is one focus of discussions within neuroethics and neurogovernance discourses [5,13,15,57] and OTs have a stake in NA due to the impact of NA on occupation and their field [2,[20][21][22][29][30][31] and their exposure to NA [16-19, 23, 35-40]. However, literature does not exist that looks at OTs as stakeholders in neuroethics and neurogovernance discourses.…”

“…As addressed earlier, occupation and humans as occupational beings are continually impacted by the development of NA, either by outdating occupations, creating new occupations, or by changing current occupations [2,[20][21][22][29][30][31]. Given the therapeutic and non-therapeutic ways that their clients are impacted by NA and the societal and environmental issues that arise [1, 2, 33], OTs have a role and responsibility to develop the knowledge on how to address such issues and support their clients [99,101].…”

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.
