Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to observe the long term efficacy and safety of cerebellar continuous θ burst stimulation (cTBS) for drug-resistant Epilepsy during enhanced and maintenance phase,in order to provide a new treatment for long-term control of drug-resistant epilepsy and improve the quality of life of those patients. A total of 100 patients with DRE will undergo cTBS treatment by precise navigation to bilateral cerebellar dentate nuclei. The frequency and clinical feature of seizures, scalp EEG,clinical score, MOCA,MMSE,and QOLIE-31 were ssessed at baseline, after 2 weeks of enhanced phase,8 weeks of consolidate phase, and 8 weeks of maintenance phase.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Participant Group

Continuous θ-burst stimulation (cTBS) is characterized by plexus stimulation. The stimulation intensity was 80% resting motor threshold (RMT) at 50Hz of intra plexus pulse while the frequency of inter plexus pulse is 5Hz, the duration was 40s, and the number of stimulation pulses was 600. Two groups of stimulation were repeated in each cerebellar dentate nucleus with an interval of 5 min in each group.

Group Type EXPERIMENTAL

cTBS

Intervention Type DEVICE

Continuous θ-burst stimulation (cTBS) is characterized by plexus stimulation. The stimulation intensity was 80% resting motor threshold (RMT) at 50Hz of intra plexus pulse while the frequency of inter plexus pulse is 5Hz, the duration was 40s, and the number of stimulation pulses was 600. Two groups of stimulation were repeated in each cerebellar dentate nucleus with an interval of 5 min in each group.

1. Enhanced phase:participants received cTBS treatment for a total of 5 times a week for 2 weeks;
2. Consolidation phase:participants received cTBS treatment for a total of twice a week (at least 24 hours apart) for 8 weeks;
3. Maintenance phase:participants received cTBS treatment for a total of once a week for 8 weeks.
