Intervention: Biofeedback
Description: Motor learning is improvement in movement overtime, followed by retaining what was learned. To determine whether movements are improving, kinematics must be assessed over time, beginning with defining specific kinematic goals, then continually re-evaluating goals throughout rehabilitation while providing the participants with biofeedback. Biofeedback is fundamental in motor learning, because it increases guidance and motivation, supplements losses in intrinsic feedback (proprioception), and facilitates generalization and retention. Biofeedback enhances the training of novel movements and could be essential for training swallowing maneuvers. Biofeedback training will occur 3 times.

Intervention: Transcranial Direct Current Stimulation
Description: Weak direct currents can be applied non-invasively, transcranially and painlessly. Such application leads to transient changes in corticomotor excitability that are fully reversible. There are no known risks of tDCS of the brain, other than mild local discomfort at the electrode sites.The tDCS sessions will be separated by at least 24hrs, the electrode pads will not be used more than 4 times and they will be clean with a sterile saline solution.

Intervention: Financial Reward
Description: Motor learning training can be enhanced by adjuvant techniques such as non-invasive neural stimulation and explicit reward. Both influence the primary motor cortex (M1), a key neural substrate of motor skill learning. Non-invasive neural stimulation reduces dysphagia after stroke as measured with subjective swallowing severity scales, however it is unknown whether it could also enhance swallowing maneuver training. Explicit reward (i.e. financial) incentivizes successful gains during motor training. Explicit reward has never been investigated in swallowing rehabilitation. However, it has been shown that increasing stress and financial penalty can reduce swallowing frequency in healthy adults.
