Robot-assisted Gait Training on Mobility in Severely Disabled Multiple Sclerosis Patients

Gait disabilities affect personal activities and quality of life of progressive multiple sclerosis (MS) patients. A robot-driven gait orthosis allowing a more effective support of walking movements and imitation of a nearly normal gait pattern during treadmill training at a higher speed has been developed and recently introduced in clinical settings. However, until now few studies evaluated the effects of Robot-Assisted Gait Training (RAGT) in a group of stroke, spinal cord injury and MS subjects. In addition, the training-induced neural and biological changes potentially related to the mechanisms of recovery remain undefined. The primary aims of this study are: to test the feasibility of RAGT in a group of progressive severely disabled MS patients and to test the hypothesis that this intensive intervention could have higher benefit, compared with conventional therapy alone, in mobility improvement as assessed by the Timed 25 Foot Walk (T25FW) The secondary aims of this study are: to determine whether fatigue, Quality of life, balance and locomotor function are improved by RAGT; to determine whether gait training influences markers of plasticity including clinical and circulating biomarkers to search for a possible correlation between clinical outcomes and clinical and circulating biomarkers
