Summary

In this study we wondered whether patients with different phenotypes of Parkinson's disease respond differently to the protocol of repetitive transcranial magnetic stimulation (rTMS) associated with physical therapy. Furthermore, the study aims to compare the effects of rTMS protocols (high and low frequency) associated with physical therapy in PD patients with different phenotypes regarding to motor performance; bradykinesia; functional mobility; balance; quality of life; perception of improvement.

  • Parkinson Disease

Interventions

COMBINATION_PRODUCT

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 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.

COMBINATION_PRODUCT

Sham repetitive transcranial magnetic stimulation

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.
