Clinical and Instrumental Treatment's Predictors in Subjects With Neurological Diseases Using G-EO Robotic System

This study is looking at which patients with neurological conditions benefit most from robotic walking rehabilitation using a device called the G-EO system. Researchers will track clinical and physical measurements before and during treatment to identify predictors of improvement. **You may be eligible if...** - You have been diagnosed with multiple sclerosis, Parkinson's disease, stroke, or acquired brain injury - You are 18 or older - You are able to walk at least 10 meters (even with a walking aid) - You are scheduled for at least 10 robotic therapy sessions (at least twice a week) - You can sit upright without support for at least 30 seconds and stand for 7 minutes - Your body size is compatible with the robotic device **You may NOT be eligible if...** - You have severe joint movement limitations - You have bone, pain, or spasticity problems that interfere with walking - You have skin sores in areas that contact the device - You have seizures that could be triggered by the G-EO system Talk to your doctor to see if this trial is right for you.
