Evaluation of the Safety and Usability of the MAK Exoskeleton in Patients With Stroke
Study Details
Study Description
Brief Summary
This study aims to evaluate the safety and usability of a motorized mobility assistance exoskeleton (MAK). The procedure explores the use of the MAK exoskeleton during the static and dynamic rehabilitation sessions with the intention to evaluate the safety and usability of the device in the studied population. The protocol has been focused on defining how the device can be used appropriately in this population in a safe manner by rehabilitation specialists.The study also aims to assess the safety of clinicians implementing the intervention, as well as possible benefits derived from the use of the device. As a secondary outcome, efficacy measurements will be collected.
