Overview
Brief Summary
Over the last years, the introduction of robotic technologies in gait rehabilitation of stroke patients has aroused great interest. Some studies have been conducted to evaluate the effects of robot-assisted training compared to conventional gait rehabilitation in patients with subacute stroke but no studies seem to investigate the effects of a combined robotic treatment (gait plus balance).
The aim of this study is to evaluate the efficacy of a combined gait and balance robotic rehabilitation compared robotic gait training alone.
Detailed Description
Stroke is not only the third cause of death after cardiovascular disease and cancer, but also the first cause of disability in the world with a significant impact on individuals, their families and finances. Post-stroke disability involves mobility and balance, muscle strength, control of movement, and gait pattern functions. Although the majority of stroke patients learns to walk independently by 6 months after stroke, gait and balance problems persist through the chronic stage and may have a significant impact on patients' quality of life. Accordingly, the restoration and improvement of walking functions is a primary concern to obtain independence in daily life. For this reason, gait recovery is a realist goal in the rehabilitation of almost all patients with stroke. The recovery of a more fluid, safe and correct execution of motor tasks such as gait and stair climbing are a prerequisite for the patients to become autonomous in the activities of daily living. Over the last years, the introduction of robotic technologies in gait rehabilitation of stroke patients has aroused great interest. Some studies have been conducted to evaluate the effects of robot-assisted training compared to conventional gait rehabilitation in patients with subacute stroke. The main results were obtained using robotic exoskeletons or a treadmill training with partial body weight support and only a few studies used an end-effector device. Preliminary studies have shown that end-effector Robot-Assisted Gait Training (RAGT) has produced promising effects on motor and functional outcomes in chronic and subacute strokes patients comparing with conventional treatment. Moreover, safe gait needs a continuous dynamic balance than it is possible that in gait robotic rehabilitation could be included a rehabilitation treatment of static and dynamic balance with a robotic proprioceptive platform. The hypothesis of the study is that a combined robotic treatment (gait plus balance) could produce more effects than just one robotic gait training. Therefore, the aim of this study is to evaluate the efficacy of gait and balance robotic rehabilitation in subacute stroke patients in terms of clinical outcomes, balance measures and gait kinematics, comparing them with robotic gait training alone. The patients following first ever stroke in sub-acute phase will be recruited and assessed both clinically and instrumentally (Gait Analysis and Balance evaluation) at baseline (T0), after 12 sessions (T1) and at the end of the training program (24 sessions: T2). The patients will be randomized into 2 groups and will conduct two different types of rehabilitation training: one group will perform, gait training using an end-effector robotic device for RAGT (Gait Group, GG); and the other group will receive a combined robotic treatment program with the same end-effector robotic system and a robotic proprioceptive platform (Balance Group, GHG). The rehabilitation program of both groups will be combined with conventional physiotherapy.

Outcomes
Primary Outcomes
Change in Berg Balance Scale (BBS)
Time Frame: Baseline (T0), Session 12 (4 weeks) (T1), Session 24 (8 weeks ) (T2)
The Berg Balance Scale is a widely used clinical test of a person's static and dynamic balance abilities. The test takes 15-20 minutes and comprises a set of 14 simple balance related tasks, ranging from standing up from a sitting position, to standing on one foot. The degree of success in achieving each task is given a score of zero (unable) to four (independent), and the final measure is the sum of all of the scores.
