Measure
Active rTMS First, Then Sham rTMS
First intervention: 10 hertz (Hz) rTMS will be administered over bilateral primary motor areas for the muscles of lower extremities. Therapy will include five daily sessions (on consecutive week days). In every sessions 3000 magnetic pulses of 90% of the resting motor threshold intensity will be elicited. The washout will last at least one month. Second intervention: Sham stimulation will mimic the active one except that the stimulating coil will be held perpendicularly to the scalp, which assures similar impression as the active stimulation but prevents that significant magnetic field will reach brain tissue. rTMS: high frequency rTMS to induce the long term potentiation of primary motor areas for the muscles of lower extremities
Sham rTMS, Then Active rTMS

Change in bilateral assessment of the strength of following movements: hip flexion, knee flexion and extension, ankle flexion and extension. Assessment will be made according to six degrees (0 to 5) MRC scale, with higher values representing stronger movements, which is better outcome. Values are averaged from all movements tested.
