Arms & Interventions
aVNS followed by no aVNS in subjects with SCI
Auricular vagal nerve stimulation (aVNS) will be provided by a device that is placed around the ear. A low-voltage electrical signal will be given for 30 minutes. In the following visit, subjects will complete all study assessments without the aVNS. Participation will be up to 2 weeks.
Intervention: auricular nerve stimulation (aVNS) (Device)
aVNS followed by no aVNS in subjects with SCI
Auricular vagal nerve stimulation (aVNS) will be provided by a device that is placed around the ear. A low-voltage electrical signal will be given for 30 minutes. In the following visit, subjects will complete all study assessments without the aVNS. Participation will be up to 2 weeks.
Intervention: sham aVNS (Device)
no aVNS followed by aVNS in subjects with SCI

Outcomes
Primary Outcomes
Number of Treatment-related Adverse Events (AEs)
Time Frame: Up to 2 weeks
Safety will be reported as the number of treatment-related AEs assessed by study PI or physician
Number of subjects that complete the study
Time Frame: Up to 2 weeks
Safety will be determined by number of subjects that complete the two study, visits (in total, two weeks).
Secondary Outcomes
No secondary outcomes reported
