Title: Body-weight Supported Therapy Using Gait Trainer Versus Traditional Gait-oriented Physiotherapy in Acute Phase of Stroke. The Effectiveness of Gait Training and Brain Networks Using NBS (Navigating Brain Stimulation)
Brief Summary: This is a trial aiming to evaluate the difference of effectiveness between two therapy methods in patients with acute stroke. The other aim is to use Navigated Brain Stimulation (NBS)to analyze changes in brain networks during the recovery and as the consequence of rehabilitation. The groups are:

* body-weight supported gate trainer rehabilitation
* gait-oriented traditional physiotherapy Patients in physiotherapy group will have 75 min physiotherapy daily every workday. This includes 20 minutes walking exercises in the traditional group while 20 minutes of gait trainer therapy in the gait trainer group. The evaluation of effectiveness of therapy in each group is made after three weeks' therapy and at six months. The goal is to have 40 patients until the end of June 2006.
