Trial Outcomes & Findings for Transcranial Direct Current Stimulation for the Treatment of Deficits After Traumatic Brain Injury (NCT NCT02613936)

NCT ID: NCT02613936

Last Updated: 2023-10-06

Results Overview

The NIH Executive Abilities: Measures and Instruments for Neurobehavioral Evaluation and Research (EXAMINER) assesses executive function in four different domains, creating a composite score from all domains, ranging from -3.0 to 2.0 with higher scores indicating better outcome.

Participant milestones
Measure
Active Anodal tDCS + Cognitive Training
In this arm, patients with mmTBI will undergo 10 sessions of active tDCS x 30 minutes combined with simultaneous cognitive training on consecutive weekdays. Anodal tDCS: Anodal tDCS lowers neuronal membrane potentials, leading to increased probability of depolarization from incoming stimuli. Cognitive training: Cognitive training involves solving executive function tasks on a computer.
Placebo Anodal tDCS + Cognitive Training
In this arm, patients with mmTBI will undergo 10 sessions of placebo tDCS x 30 minutes combined with simultaneous cognitive training on consecutive weekdays. Cognitive training: Cognitive training involves solving executive function tasks on a computer.
