The main aim of this study is to investigate the preferences of individual stroke patients for key features of an exoskeleton, intended for lower limb rehabilitation, with a view to its potential integration into the design of future exoskeletons. This will be a multicenter study. Patients will be presented different scenarios of choices about the attributes about gait exoskeleton.

Conditional logistic regression models will be used to define the preferences of the subjects.
