Clinical Trial Summary

To determine the biophysical impact of biophysical Impact of Transcutaneous Spinal Cord Stimulation (TSCS) within a single session. We hypothesize that subjects will demonstrate increased volitional muscle strength with TSCS. This will be assessed by isokinetic strength testing of post-injury dominant-side knee extension. Subjects will be tested in both Transcutaneous Spinal Cord Stimulation and sham conditions.


Clinical Trial Description

The investigators will conduct isokinetic strength testing (via the Biodex) of post-injury, dominant-side knee extension before, during, and after TSCS and a sham condition. Transcutaneous Spinal Cord Stimulation will be applied (via the Vectra Neo) using a 5cm x10cm oval electrode placed midline on the skin between spinous process T11 -T12 as a cathode and two 7.5cm x 13cm rectangular electrodes placed symmetrically on the skin over the lower abdomen as anodes. A symmetrical biphasic rectangular waveform, at 50Hz and 1millisecond, will be used to provide 30 continuous minutes of stimulation. As sham procedures for this intervention have not been established, the investigators will follow sham procedures well documented in Transcranial DC Stimulation (tDCS). Electrodes will be placed as they are in the Transcutaneous Spinal Cord Stimulation condition. Stimulation will be applied at subject's maximum intensity for 30 seconds and then discontinued. Subjects will participate in two testing sessions, each approximately one hour in length, separated by at least 24 hours.

Subject's starting condition will be randomized. Subjects will be informed that two stimulation conditions are being tested, but will not be told which is the experimental condition. ;
