Brief summary
In this project, we aim to determine any potential effects of a weak electrical current applied to the neck or thoracic area on functional capacity and muscle activation. Healthy individuals will participate in one familiarization followed by up to 6 experimental sessions. Fatigability and motor function will be assessed in each test session.
Detailed description
This project will investigate the potential impact of an electrical current of low intensity, and applied non-invasively, on the signals that drive muscle contractions. Individuals will receive distinct types of stimulation that vary depending on the direction on the current (anodal vs cathodal) and placement of the electrodes. These conditions will be compared to a sham stimulation. The test session will be randomized in a double blind fashion, which indicates that neither participants or investigators will know the type of stimulation. Motor function and the muscle electrical activity will be quantified during each test session.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Force | Each session will take approximately 2 hours (total of 4 test sessions) | Change in force will be evaluated with a device during each test session |
| Perception of effort | Each session will take approximately 2 hours (total of 4 test sessions) | Change in perceived effort will be evaluated with visual analogue scales |
| Muscle activation | Each session will take approximately 2 hours (total of 4 test sessions) | Electromyography will be used to quantify muscle activation |
