We are looking for volunteers to participate in a study to measure skill and strength of muscles involved in swallowing. We want to determine whether there are any patterns of swallowing impairment within people who have stroke or myopathy, compared to healthy people. This study will give us a better understanding of what happens to swallowing when the brain and/or muscles are damaged, and how we can improve treatment. 

If you agree to take part in this study, we will place a sensor under your chin to measure muscle activity and muscle force. You will complete the following 4 tasks:

  1. Swallow as hard as you can.

  2. Open your jaw against resistance.

  3. “Hit” a target on a computer screen by controlling the timing and force of your swallowing.

  4. “Hit” a target on a computer screen by controlling the timing and force of your mouth opening.

You will also fill out a health questionnaire and participate in a clinical swallowing evaluation. The study will take 60-90 minutes and will be completed in one visit.

You will receive a $10 voucher for reimbursement of travel expenses. If you agree to take part in this study, you are free to withdraw at any time, without having to give a reason.
