Purpose: Wearable lower-limb robotic exoskeletons have emerged as promising tools for locomotor training in individuals with spinal cord injury (SCI). However, their bulky size, high cost, and limited usability hinder widespread acceptance. User-centered methods identifying end-users' unique insights are key to meet their specific challenges.

Article Synopsis
  • The ABLE Exoskeleton has proven safe and feasible for individuals with spinal cord injuries (SCI) during clinical testing, but its effectiveness in home and community settings has not been previously assessed.
  • A user-centered design process was utilized to evaluate the ABLE Exoskeleton's capability for performing essential tasks in everyday environments and to gather feedback for developing a personal-use version.
  • The study involved 10 SCI participants undergoing a training program, revealing that while some experienced minor device-related issues, most achieved increased independence and were able to don and doff the device with minimal assistance.

Studies on robotic interventions for gait rehabilitation after stroke require: (i) rigorous performance evidence; (ii) systematic procedures to tune the control parameters; and (iii) combination of control modes. In this study, we investigated how stroke individuals responded to training for two weeks with a knee exoskeleton (ABLE-KS) using both Assistance and Resistance training modes together with auditory feedback to train peak knee flexion angle. During the training, the torque provided by the ABLE-KS and the biofeedback were systematically adapted based on the subject's performance and perceived exertion level.
