Participant Flow

Participants enrolled from flyers and word of mouth at Washington University in St. Louis. The first participant was enrolled on 06/23/2022, the last participant was enrolled on 03/06/2023.

Recruitment was only perform for the second arm of the study: evaluating reticulospinal tract contributions during different types of movements. Participants performed range-of-motion and precision-control tasks in randomized order during the same session. As this study was terminated early based on change in funding, no participants were assigned to the "Evaluation of Motor Evoked Potentials" arm, and no data could be provided for this outcome measure.

PRIMARY outcome

Timeframe: 30 minutes before and 30 minutes into intervention

This primary outcome is a measure of changes in corticospinal tract excitability as quantified by changes in the amplitude size of motor evoked potentials. Data for this arm were not collected due to early study termination.

Outcome data not reported

PRIMARY outcome

Timeframe: During intervention, *1 Day*.

Population: The average across all participants is reported.

This primary outcome measures changes in reticulospinal tract excitability (RST) during training as quantified by changes in reaction time after a startling auditory stimulus. RST contrubution was evaluated for dorsiflexion, plantarflexion, hip flexion movements during precision and range of motion control tasks under three conditions: with transcutaneous spinal cord stimulation or without stimulation. All conditions/evaluations were performed in the same session. 30 repetitions were performed per condition during a single session and averaged for each participant. RST is a ratio calculated by = (visual - startle)/(visual - auditory), where: visual represents the reaction time to a visual cue, auditory represents the reaction time to an auditory cue, startle represents the reaction time to a startling cue. A RST ratio value greater than 1 would indicate a significant contribution of the reticulospinal tract for a given task. A value equal or lower than 1 would suggest
