Usability and acceptability by a younger and older user group regarding a mobile robot-supported gait rehabilitation system

ABSTRACT

The aim of the study was to identify differences regarding usability, acceptability, and barriers of usage of a robot-supported gait rehabilitation system between a younger and older group of patients with gait impairments. A mobile robot-supported gait rehabilitation prototype was tested on a group of geriatric patients aged 60 and above, and on a group of young patients aged 59 and below in a clinical setting during five therapy sessions. The involved therapists received 2 days training with the system and could test it profoundly. Data on usability, acceptability, and barriers to system usage were collected with questionnaires and structured interviews with the patients. The robotic system received overall moderate usability and good acceptability ratings; it was rated as clearly structured, practical, and safe. Analyses identified a few barriers, such as time-intensive setup of the system or tight leg shells, which can be minimized with regular training and system adaptations. Differences between the two user groups could be revealed and will be used for future investigation. This study showed the potential of the mobile robot-supported system for gait rehabilitation, but also pointed out further need for action. Efficacy studies are the next step in the evaluation process.
