Pilot Testing of a New Questionnaire for the Assessment of User Experience During Exoskeleton-Assisted Walking

Scientific literature provides weak attempts in analyzing user experience during the use of rehabilitation and assistive wearable robotic devices. The objective of this study is to develop and preliminary test a new questionnaire evaluating the subjective perspective of people using lower limb exoskeletons. A literature search was conducted to investigate acceptance and usability/quality models, theories and questionnaires with the aim of extracting relevant factors to be considered. A four-factor questionnaire was developed and its feasibility was tested on four participants with central nervous system lesions walking with overground and treadmill-based exoskeletons in rehabilitation scenarios.
