Repetitive Transcranial Magnetic Stimulation in Essential Tremors Patients

Al-Azhar University30 enrolled

Overview

The aim of the study is to investigate the Effect of Repetitive Transcranial Magnetic Stimulation on Essential Tremors.

Prior to start of rTMS sessions, Clinical evaluation and scaling of tremors using the ET rating scale (Fahn, Tolosa, Marin Tremor Rating Scale) will be employed on the participants in both groups. rTMS frequency of 1Hz will be delivered to each of the participants in both groups. Each session will be administered once daily for 3 days a week for 4 weeks. 1200 pulses (30 pulses per train with total 40 trains having inter-train delay of 3 seconds) per session will be provided with the coil placed on both cerebellar hemispheres. rTMS frequency of 1Hz was kept constant based on previous studies. rTMS sessions will be administered by trained professionals who was kept blinded to the research protocols used in the study. After completion of therapeutic programs (after 4 weeks), the participants will be asked to undergo post assessment of Fahn, Tolosa, Marin Tremor Rating Scale at the end of last rTMS session, 1 month, 3 months later.

Interventions

Repetitive Transcranial Magnetic StimulationDEVICE

TMS device will deliver repetitive trains of magnetic pulses using Magstim Rapid 2 with angulated figure of eight shaped coil. The device comprised two-channel Neuro-EMG-MS digital system for determining the motor threshold of the patients that will be used for establishing the threshold intensity for stimulation. The figure of eight-shaped coil generated a magnetic field of up to 4 Tesla that penetrates the cranium, enters into the soft tissue of the brain and henceforth stimulates the motor neurons.
