|---|---|---|---|
| aVNS followed by no aVNS in subjects with SCI | Experimental | 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. |

| auricular nerve stimulation (aVNS) | Device | The Spark Sparrow system stimulates the auricular branch of the Vagus nerve using a low-voltage electrical signal comprising a 1 Hz - 150 Hz biphasic square wave with a pulse width of 50s - 750s. Stimulation current is controlled with a maximum voltage of 95 V and 1-5 milliamperes (mA) output current. The device is positioned at the auricular branch of the Vagus nerve on the ear with the outer electrode in front of the ear and the inner electrode into the hollow area of the ear, just above the ear canal. Stimulation will occur for 30 minutes. Participation will last up to 2 weeks and requires 2 separate in-person visits. Each visit will be up to 3 hours. |
| Measure | Description | Time Frame |
|---|---|---|
| Number of Treatment-related Adverse Events (AEs) | Safety will be reported as the number of treatment-related AEs assessed by study PI or physician | Up to 2 weeks |
| Number of subjects that complete the study | Safety will be determined by number of subjects that complete the two study, visits (in total, two weeks). | Up to 2 weeks |

| sham aVNS | Device | The Spark Sparrow system device will be positioned at the auricular branch of the Vagus nerve on the ear with the outer electrode in front of the ear and the inner electrode into the hollow area of the ear, just above the ear canal. Subjects will wear the device for 30 minutes during which no stimulation will be emitted. Participation will last up to 2 weeks and requires 2 separate in-person visits. Each visit will be up to 3 hours. |
