The Effects of Gait Rehabilitation After Stroke by Treadmill-based Robotics Versus Traditional Gait Training

This multicenter non-randomized controlled trial aims: * to investigate the efficacy of a treadmill-based robotic treatment (both end-effector and exoskeleton) compared to the conventional rehabilitative treatment on gait recovery in stroke survivors; * to verify different effects of the end-effector or exoskeleton system on stroke subjects with different disabilities. All the eligible subjects (please, see the inclusion and exclusion criteria), admitted to the study participant centers for rehabilitation treatment, will be recorded at any stage of the rehabilitation program (subacute or chronic phase). The patient's recruitment will run following the authorization of the respective Ethics Committees for 12 months. Both experimental or control group will be undergone to 20 sessions of treatments, from 3 to 5 times per week, each lasting 60 minutes ( for a total of 400 minutes of treatment) All robotic systems used in this study for the experimental group (Lokomat Pro - Hocoma AG, Volketswil, Switzerland; G-EO System - Rehatechnologies, Italy) are treadmill-based and do not provide the over-ground gait training. They are characterized by the possibility of a programmable load suspension, as well as speed, stride length. The patient's activity with the related data is always displayed and stored with a computerized control system. The control group will follow a traditional gait rehabilitation for the same duration as the experimental group. The clinical assessments and data analysis will be carried out blindly.
