User-centered design and development of TWIN-Acta: A novel control suite of the TWIN lower limb exoskeleton for the rehabilitation of persons post-stroke

This research focuses on creating a new control system called TWIN-Acta for the TWIN lower limb exoskeleton, designed to help people who have had a stroke to walk better. The goal is to provide assistance as needed, tailoring the support to each person's abilities. The development process involved experts including clinicians and engineers, who worked together to ensure the system met the needs of stroke patients. They considered common walking problems faced by these patients. The system was tested by clinical experts and people post-stroke to assess its usability and acceptability. The results showed that the system was generally well-received and considered useful for gait rehabilitation.

• 1
  The TWIN-Acta system received overall good usability and acceptability ratings from clinical experts.
• 2
  Experts found the ability to adjust the assistance provided by the exoskeleton during movement execution to be a valuable feature.
• 3
  The main limitation identified was the low level of system learnability, which can be improved with prolonged training.
