Translingual Neurostimulation for the Virtual Treatment of Post-Traumatic Stress Disorder: A Feasibility Pilot

NCT ID: NCT05112003

Last Updated: 2023-08-03

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 10 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2021-09-22
• Study Completion Date: 2023-07-06

Brief Summary

A growing body of evidence suggests that translingual neurostimulation (TLNS) plays a role in modulating neuroplastic changes in the brain, which has far-reaching implications for its ability to facilitate other therapeutic interventions such as cognitive processing therapy (CPT) for post-traumatic stress disorder (PTSD). The present study aims to assess the feasibility of combining TLNS with CPT in individuals with PTSD.
