the ear clip is uncomfortable and compliance is down as a result. The team is working with manufacturer to develop new ear clip that will be used in a new protocol.

Outcome Measures
Primary Outcomes (2)
Change in High-frequency Heart Rate Variability (hfHRV) at 4 Weeks
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.
Assessed at baseline and 4 weeks.
Rate of Compliance With Daily TENS Usage
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.
Assessed daily for duration of study (4 weeks) via self-report recording journal.
