Purpose
Stroke are the main causes of motor disability among adults and are expected to impose an increasing social and economic burden for our Country. The impact of stroke on patients is enormous, with negative ramifications on the persons participation in social, vocational, and recreational activities. It is the primary cause of long-term disability in these countries. At the present stage, it is well known that control of balance during upright standing depends upon the central integration of afferent information from vestibular, somatosensory (proprioceptive, tactile), and visual systems, which constitute a multilink neural network for the control of neck, hip, and ankle joints. More recently, it has been studied at the level of cerebral cortex; vestibular inputs would reach face/neck representation of primary somatosensory cortex and would be then integrated with visual and somatosensory inputs in intraparietal, posterior end of the insula and medial superior temporal cortices. Remarkably, balance impairment and the associated risk of falling represent one of the most prominent and potentially disabling features in stroke subjects. The specific aims of this project are: to verify whether the robotics lower limb treatment with body weight support is more effective than the treadmill treatment in the reduction of motor impairment in Stroke patients, and to improve the quality of the gait and the endurance and to analyze possible improvements in terms of physiological biomechanical gait through analysis of spatio-temporal parameters.

Experimental: Robot G-EO
Each subject will be asked to perform 15 sessions (3 to 5 days a week for 4 up to 5 weeks) consisting of a treatment cycle using the GE-O system device, according to individually tailored exercise scheduling.
|
Device: Robot-assisted walking
The practice will included an add-on robot-assisted walking therapy at variable speeds for 40 min with a partial body weight support (BWS). All participants will start with 30-40% BWS and an initial treadmill speed of 1.5 km/h speed will be increased to a range of 2.2 to 2.5 km/h and the BWS % will be decreased.

Detailed Description:
Objective: to assess the lower limb recovery after the gait rehabilitation training exercises in acute and chronic stroke patients.
The proposed project, through a Randomized controlled observer-blind trial aimed at evaluating the effectiveness of end-effector robot assisted therapy vs the treadmill and ground treatment in sub-acute and chronic stroke subjects. 90 inpatients and out-patients with a stroke will be recruited. We will randomize the patients on 3 groups [15 sub-acute (ischemic and hemorrhagic) stroke patients (after 30±7 days from injury) and 15 chronic (ischemic and hemorrhagic) patients (after 3/6 months days from injury) for all groups]:
- sub-acute and chronic stroke patients robot treatment.
- sub-acute and chronic patients treadmill treatment.
- sub-acute and chronic patients ground treatment.
The specific aims of this project are:
- to verify whether the robotics end-effector GEO lower limb treatment with body weight support is more effective than the treadmill treatment or ground treatment in the reduction of motor impairment in sub-acute and Chronic stroke patients, and to improve the quality of the gait and the endurance;
- to analyse possible improvements in terms of physiological biomechanical gait through analysis of kinematics , kinetics and EMG evaluation;
- to analyse possible improvements in terms of reduction of instable posture and movements, which can represent a reduction of the risk of fall typical of these subjects;
- to evaluate the kinematic, kinetic and EMG quantitative data during selected movements (gait, posture, ) compared with age matched reference data;
- to investigate the stability of the effects of robot-assisted treatment at 4/6 months follow-up in terms of Quality of Life (QoL).
A first goal of this project is to investigate the differences in improvement of the quality and safety of the gait (motor performance and functional recovery) through kinematic/kinetic and EMG parameters (Change in Step Length, Change in Gait Velocity and Change in Stride Time Variability, 3D joints kinematics, ground reaction forces, joint kinetics, muscle activation,) and traditional clinical scales in sub-acute and chronic stroke patients.
The second goals is aimed at identifying possible advantages in the QoL of patients undergoing such a kind of in-patients and out-patients rehabilitation treatment and at investigating novel methods enabling lower limb functional recovery, leading to wide potential for regaining personal independence.
The third goal is to analyse direct cost savings associated with the use of such technologies, measured as direct, indirect and intangible costs, through specific HTA procedures.
