Abstract: Individuals using upper extremity prostheses often struggle with activities of daily living. The most challenging tasks to execute with a prosthesis are those requiring cooperation between the prosthesis and the intact hand, e.g., cutting bread or tying shoelaces. In our ongoing research, we apply a user-centred design approach to develop and implement a machine learning algorithm (MLA) that can recognize and classify movement intentions based on EMG signals of both the stump, as well as the intact upper extremity. The goal is that the MLA recognizes task intentions and that the prosthesis can naturally execute the corresponding movements at high speed and precision. To get a deeper understanding of the difficulties, needs and experiences of myoelectric prosthesis users, we are conducting a pilot study with three semi-structured interviews and a qualitative content analysis. In a first analysis, we identified different aspects with potential for improvement regarding task performance. Interviewees indicated that the lack of speed of prosthesis movement limited its usefulness to the extend where users preferred doing a task single-handed rather than with the prosthesis. Further, the selection of different grips through the human-prosthesis interface was perceived as non-natural and cumbersome. In addition, several specific tasks were identified, where the biggest potential for improvement is expected, such as typing on a cell phone or turning pages in a book. Interviewees also mentioned tasks that are often conducted at the same time and hence need cooperation between the hands, such as using a blow dryer and hairbrush. Results from these pilot interviews will, in combination with pilot EMG analysis, inform the planning of our larger study. We plan to design an MLA that is compatible with commercially available myoelectrical arm prostheses. We further see future potential to extend the algorithm to other use cases, such as exoskeletons.
