Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Treatment - Participants will be randomly allocated to one of the following experimental protocols: (i) real high frequency rTMS + physical therapy protocol; (ii) real low frequency rTMS + physical therapy protocol; (iii) rTMS sham + physiotherapeutic protocol. The sessions will be performed five times a week for two weeks. Individuals allocated to the high frequency rTMS group will be performed the following protocol: first the coil center will be positioned over Cz for the first 1000 pulses. Then the coil will be moved to C4 and C3, where 1000 pulses will be delivered to each hemisphere. The intensity will be set to 100% of the motor threshold. The high frequency stimulation will be delivered at 10 Hz, offered in 20 50-pulse trains, with 30-second train intervals. The low frequency will be performed at 1 Hz. All groups will be treated with physical therapy immediately after rTMS.

High frequency rTMS + physical therapy
The sessions will be performed five times a week for two weeks. The individuals will be performed the following protocol: first the coil center will be positioned over Cz for the first 1000 pulses. Then the coil will be moved to C4 and C3, where 1000 pulses will be delivered to each hemisphere. The intensity will be set to 100% of the motor threshold. The high frequency stimulation will be delivered at 10 Hz, offered in 20 50-pulse trains, with 30-second train intervals. After rTMS, patients will be submitted to 40 minutes of physical therapy protocol.
High frequency repetitive transcranial magnetic stimulation
The sessions will be performed five times a week for two weeks. The individuals will be performed the following protocol: first the coil center will be positioned over Cz for the first 1000 pulses. Then the coil will be moved to C4 and C3, where 1000 pulses will be delivered to each hemisphere. The intensity will be set to 100% of the motor threshold. The high frequency stimulation will be delivered at 10 Hz, offered in 20 50-pulse trains, with 30-second train intervals. The low frequency will be performed at 1 Hz. After rTMS, patients will be submitted to 40 minutes of physical therapy protocol.
Low frequency rTMS + physical therapy
The sessions will be performed five times a week for two weeks. The individuals will be performed the following protocol: first the coil center will be positioned over Cz for the first 1000 pulses. Then the coil will be moved to C4 and C3, where 1000 pulses will be delivered to each hemisphere. The intensity will be set to 100% of the motor threshold. The low frequency will be performed at 1 Hz. After rTMS, patients will be submitted to 40 minutes of physical therapy protocol.

After rTMS, patients will be submitted to 40 minutes of physical therapy protocol.
Sham rTMS + physical therapy
For sham stimulation, the stimulator positioned behind the patient will be turned off immediately after the determination of RMT, however, the coil will remain positioned over the patient's scalp (Cz, C3 and C4). A computer equipped with speakers will play an audio recording with the characteristic rTMS sound and no stimulation will be induced in the brain.
