Brief Summary

Gait recovery is one of the main goals of post-stroke rehabilitation where robotic-assisted practice has shown positive outcomes. However, literature lacks of clinical studies on exoskeleton-supported gait rehabilitation. Recently, a wearable exoskeleton (Ekso™, EksoBionics, USA) has been commercialized for re-enabling patients to stand and walk, involving them directly in steps trigger through body weight balance. The main aim of this study is to assess the clinical and neuromuscular effects of exoskeleton-based gait rehabilitation in sub-acute and chronic stroke patients, compared to patients with similar characteristics who will conduct a traditional over-ground gait training. In this multicentric RCT, 162 stroke patients will be enrolled and randomly assigned to the Experimental Group (EG) or to the Control Group (CG). Patients will conduct at least 12 one-hour-sessions (about 3 times/ week) of Ekso™ (EG) or traditional over-ground (CG) gait rehabilitation. Clinical evaluations (lower limb Modified Ashworth Scale- MAS; Motricity Index - MI; Trunk Control Test - TCT; Functional Ambulation Classification - FAC; 10-meter walking test - 10mwt; 6-minute walking test - 6mwt; Walking Handicap Scale - WHS; Time Up and Go - TUG) will be administered to patients at the beginning (T1) and at the end (T2) of the training period. The primary outcome is the distance performed during the 6mwt. A follow up study at 1 month (T3) and at 3 months (T4) after T2 will be conducted.

Outcome Measures

Primary Outcomes (1)

  • Change in 6 Minute Walk Test (6MWT)

    The 6MWT measures the distance a subject covers during an indoor gait on a flat, hard surface in 6 minutes, using assistive devices, as necessary. The test is a reliable and valid evaluation of functional exercise capacity and is used as a sub-maximal test of aerobic capacity and endurance. The minimal detectable change in distance for people with sub-acute stroke is 60.98 meters. The 6MWT is a patient self-paced walk test and assesses the level of functional capacity. Patients are allowed to stop and rest during the test. However, the timer does not stop. If the patient is unable to complete the test, the time is stopped at that moment. The missing time and the reason of the stop are recorded. This test will be administered while wearing a pulse oximeter to monitor heart rate and oxygen saturation, also integrated with Borg scale to assess dyspnea.

Study Arms (2)

Exoskeleton-Assisted Gait Training

EXPERIMENTAL

Patients conduct sessions of gait training, each lasting 60 minutes, using the powered wearable exoskeleton (Ekso) in addition to conventional therapy. Before the treatment's beginning, a PT checks the correct alignment of the subject's joints with Ekso and the areas of greater pressure between body's skin and device, to set a proper Ekso fit as to customize the padding as well. The best individualized exoskeleton settings should be verified to plan a tailored robotic treatment. During treatment, subjects are trained to interface with the Ekso, with optimal postural arrangement and weight shifting strategies. No strength is required from the patient; only an appropriate balance and weight shifts are necessary to achieve walking, since steps are triggered by the user's lateral weight shift.

Device: Exoskeleton-Assisted Gait Training

Traditional Over ground Gait Training

NO INTERVENTION

The Control Group (CG) performs 60 minutes. lasting sessions of Traditional Over ground Gait Training with a senior PT. In the starting phase, the gait task facilitation is allowed by the Pt's assistance or by using aids, such as walkers, tripods etc. Traditional Over ground Gait Trainings include: * Sit-to-Stand tasks * Exercises for upright position control (right/left load shift): these tasks will allow to include people who are unable to walk in the CG. CG patients will not use any other robots or treadmill for gait training.
