A questionnaire-based survey of board-certified rehabilitation physicians was conducted to identify issues in multidisciplinary interprofessional collaboration and to assess the abilities of board-certified rehabilitation physicians needed to develop assistive devices for individuals requiring long-term care. From the 366 responses, it was revealed that they consider “the ability to gain an insight into what patients need from assistive devices” and the “ability to communicate” as essential abilities needed to develop assistive devices. The respondents considered the ability to communicate and convey information important to overcome differences in thought-process between disciplines；the sharing of information, objectives, and knowledge as a requirement for teamwork；and collaboration, including with the patients, to be important. This approach to device development fits well with “design thinking” and “biodesign.” Unfortunately, more than 70％ of the respondents were unfamiliar with these concepts. Therefore, it is necessary to provide opportunities for rehabilitation physicians to learn innovative biodesign approaches.
