Study: NCT02659826

Intervention type: DEVICE
Group type: SHAM_COMPARATOR
Intervention: Gait training
Description: It consists of moderate gait training exercise for 20 minutes. To ensure that the exercise will be performed at moderate intensity will be used the 64% - 76% of maximum heart rate (HRmax = 220-age). Heart rate will be monitored every three minutes through a heart polar. In addition will be monitored perceived effort, gait speed and inclination of the treadmill. The Borg scale will be used to evaluate perceived effort. This is an analogue scale graded from 6 (light exercise) to 20 points (exhaustive exercise). Information about the exercise on the treadmill will be noted in the evolution record.

Group type: EXPERIMENTAL
Intervention: High frequency rTMS
Description: Initially, the higher cortical representation area (hotspot) of first right dorsal interosseous (FDI) muscle will be determined through a figure-eight coil connected to the magnetic stimulator (Rapid2, Magstim, UK) held manually and positioned over the scalp (C3 - 10/20 System) at an angle of 45 degrees from the midline pointed to the target muscle (FDI). Thereafter, RMT will be measure. rTMS protocols was based on previous studies. High frequency protocol: 20 hertz (Hz), 90% RMT, 45 trains, 40 stimuli per train, inter interval of 28 seconds, 1800 stimuli. After each rTMS session, presence of adverse effects will be computed.

Intervention: Low frequency rTMS
Description: Initially, the higher cortical representation area (hotspot) of first right dorsal interosseous (FDI) muscle will be determined through a figure-eight coil connected to the magnetic stimulator (Rapid2, Magstim, UK) held manually and positioned over the scalp (C3 - 10/20 System) at an angle of 45 degrees from the midline pointed to the target muscle (FDI). Thereafter, RMT will be measure. Low frequency protocol: 1Hz, 90% RMT, 1500 stimuli (1 train). After each rTMS session, presence of adverse effects will be computed.

Intervention: sham rTMS
Description: The hotspot of first right dorsal interosseous (FDI) muscle will be determinate through a figure-eight coil connected to the magnetic stimulator positioned over the motor primary cortex (C3). Then, the motor threshold (RMT) of FDI will be measure. Sham rTMS will be performed with low frequency (1Hz, 90% RMT, 1500 stimuli) protocol using two coils. The first one - connected to the stimulator - will be positioned on a coil support close to the volunteer but not visible. Therefore, characteristic stimulation noises will be audible. The second - disconnected to the stimulator - will be placed over left primary motor area. After each rTMS session, presence of adverse effects will be computed.
