Trial Outcomes & Findings for Transcutaneous Electric Nerve Stimulation (TENS) for Vagal Modulation (NCT NCT05987813)

NCT ID: NCT05987813

Last Updated: 2024-12-27

Results Overview

Determine if microstimulation over a 4 week period results in improvement in hfHRV power. Average hfHRV power was calculated at baseline and 4 weeks. The change in average hfHRV power in milliseconds squared from baseline to 4 weeks was calculated for each participant. The average change for each group is reported.

PRIMARY outcome

Timeframe: Assessed daily for duration of study (4 weeks) via self-report recording journal.

Determine the compliance rate of adolescents utilizing a microstimulator. Compliance rate calculated as number of minutes unit was used (summed from all self-report daily recording journals) divided by 3360 (the total number of minutes the unit could have been used if the participant used it for 2 hours daily for 4 weeks). The rate average for each group is reported.
