Group Intervention Description active eMNS Active eMNS Subjects with receive active eMNS for 20 minutes. sham eMNS Sham eMNS Subjects with receive sham eMNS for 20 minutes.
- Primary Outcome Measures
Name Time Method VAS Between Visit 2 and 3...where Visit 1 = baseline, Visit 2 = stimulation visit, randomly assigned sham or active (about 2 days from baseline), and Visit 3 = other stimulation visit, sham or active - one not received before (about 1 week from visit 2) Pain threshold as measured by Visual Analogue Scale (VAS) between Visits 2 and 3
DNIC Between Visit 2 and 3...where Visit 1 = baseline, Visit 2 = stimulation visit, randomly assigned sham or active (about 2 days from baseline), and Visit 3 = other stimulation visit, sham or active - one not received before (about 1 week from visit 2) Pain threshold as measured by Descending Noxious Inhibitory Control (DNIC) between Visits 2 and 3
PPT Between Visit 2 and 3...where Visit 1 = baseline, Visit 2 = stimulation visit, randomly assigned sham or active (about 2 days from baseline), and Visit 3 = other stimulation visit, sham or active - one not received before (about 1 week from visit 2) Pain threshold as measured by Pressure Pain Threshold (PPT) between Visits 2 and 3 (active stimulation and sham, order randomized).
- Secondary Outcome Measures
Name Time Method Heart rate Visit 1, 2, and 3...where Visit 1 = baseline, Visit 2 = stimulation visit, randomly assigned sham or active (about 2 days from baseline), and Visit 3 = other stimulation visit, sham or active - one not received before (about 1 week from visit 2) Heart rate as measured by a standard electrocardiogram
Attention Task Visit 2 and 3...where Visit 1 = baseline, Visit 2 = stimulation visit, randomly assigned sham or active (about 2 days from baseline), and Visit 3 = other stimulation visit, sham or active - one not received before (about 1 week from visit 2) Cognitive Performance (for attention) as measured by the Attention Network Task
N Back test Visit 2 and 3...where Visit 1 = baseline, Visit 2 = stimulation visit, randomly assigned sham or active (about 2 days from baseline), and Visit 3 = other stimulation visit, sham or active - one not received before (about 1 week from visit 2) Cognitive Performance (for working memory) as measured by the
EEG Visit 2 and Vist 3...where Visit 1 = baseline, Visit 2 = stimulation visit, sham or active (about 2 days from baseline), and Visit 3 = stimulation visit, sham or active (about 1 week from visit 2) Spontaneous oscillatory brain activity as measured by EEG using a wireless Enobio system (Neuroelectrics, Barcelona, Spain).
Time to fatigue Visit 2 and 3...where Visit 1 = baseline, Visit 2 = stimulation visit, randomly assigned sham or active (about 2 days from baseline), and Visit 3 = other stimulation visit, sham or active - one not received before (about 1 week from visit 2) Time to fatigue as measured by total cycling time at 80% of peak power.
Perception of physical exertion Visit 1, 2, and 3...where Visit 1 = baseline, Visit 2 = stimulation visit, randomly assigned sham or active (about 2 days from baseline), and Visit 3 = other stimulation visit, sham or active - one not received before (about 1 week from visit 2) Perception of physical exertion as measured by the 6-20 Borg Scale
Respiratory rate Visit 1, 2, and 3...where Visit 1 = baseline, Visit 2 = stimulation visit, randomly assigned sham or active (about 2 days from baseline), and Visit 3 = other stimulation visit, sham or active - one not received before (about 1 week from visit 2) Respiratory rate as measured by a belt transducer
