Usability Study of an Intelligent Robotic Walker for Lower-Limb Motor Training

The RoboTrainer is an intelligent robotic walker that provides force-controlled lower-limb motor training. This short paper presents the results of a usability study using the standardized System Usability Scale (SUS) questionnaire. The average SUS score from 28 healthy participants was 76.6 ± 12.5. We compared this score with a meta-analysis of 67 robotic rehabilitation devices, demonstrating that the RoboTrainer’s usability exceeds the field’s average. These findings suggest the technology has strong potential for successful adoption.
