All participants engaged in the study will participate once weekly for six weeks at Hennepin Healthcare Systems, Inc. (HHS). Each participant will be randomized into the block design of sham or tACS/tnVNS during the first three appointments or the last three appointments. While participating, both the tACS and tnVNS will be applied in accordance with the manufacturer's suggested use. Participants will complete computer-based tasks, while taking part in either the sham or tACS/tnVNS stimulation. The study is investigating the use of neuromodulation after Traumatic Brain Injury (TBI) for improved cognitive function.
This is a preliminary, prospective interventional study to investigate the feasibility of using transcutaneous alternating current stimulation (TACS) and transcutaneous noninvasive vagal nerve stimulation (tnVNS) after a traumatic brain injury (TBI) to improve cognitive function and decision-making.
