Common prosthetic options do not allow for enough independent control signals to control all the movements of the arm. Invasive approaches to obtain prosthetic control signals are being developed to provide people with upper limb loss improved prosthetic control and feedback.
OBJECTIVE/HYPOTHESIS: This study explored the prosthetic qualities that are important to users and examined the factors that play into the decision to consider invasive prosthetic interfaces that allow for enhanced prosthetic control.
Individuals participated in semi-structured focus groups or in individual semi-structured interviews (N = 11). A semi-structured interview guide containing open-ended questions was used to learn about ideal prosthesis qualities and interest in prosthetic technology interfaces including targeted muscle reinnervation, peripheral nerve interface, and cortical interface. Qualitative content analysis with an inductive approach was used for transcript analysis.
Participants were most interested in improving the dexterity and durability of prosthetic options. Recovery time, anticipated risk, medical co-morbidities, and baseline functional status influenced willingness to consider invasive prosthetic interfaces. Participants were interested in learning more about all three invasive interfaces but had the most concerns about cortical interfaces.
Attitudes toward invasive control interfaces vary. Further education on invasive control interfaces and additional conversations between prosthetic developers and people with limb loss will help to develop effective prosthetic devices that potential consumers will use.
常见的假肢选择方案无法提供足够的独立控制信号来控制手臂的所有运动。为了为上肢缺失者提供更好的假肢控制和反馈，正在开发侵入性方法来获取假肢控制信号。
目的/假设：本研究探讨了对使用者很重要的假肢品质，并研究了影响人们考虑使用增强型假肢控制接口的因素。
参与者参加了半结构化焦点小组或单独的半结构化访谈（N=11）。使用包含开放式问题的半结构化访谈指南，了解理想的假肢品质以及对假肢技术接口的兴趣，包括靶向肌肉再支配、周围神经接口和皮质接口。采用归纳法的定性内容分析用于分析转录本。
参与者最感兴趣的是提高假肢选择的灵活性和耐用性。恢复时间、预期风险、合并症和基线功能状态影响了他们对侵入性假肢接口的意愿。参与者对所有三种侵入性接口都很感兴趣，但对皮质接口最担心。
对侵入性控制接口的态度因人而异。对侵入性控制接口进行更多教育，并在假肢开发人员和肢体缺失者之间进行更多对话，将有助于开发出潜在使用者愿意使用的有效假肢设备。
