The Effect of Cognitive Tasks on Single Limb Balance
United States39 participantsStarted 2019-08-18
Plain-language summary
Purpose of the Study: The purpose of this study is to evaluate the effects of performing various cognitive tasks on balance in individuals with chronic ankle instability and healthy controls. Three different cognitive tasks will be performed while participants balance on one limb. Chronic ankle instability is defined as having a history of at least one ankle sprain and having residual effects. The specific aims of this study are to:
1. Determine if performing the cognitive tasks effect single limb balancing.
2. Determine which cognitive task, if any, has the greatest effect on single limb balance.
Participants will perform single-limb balancing with eyes open on the force plate while performing one of the four cognitive tasks. You will start with the control condition, the order of cognitive tasks will be random. Testing will occur on both limbs.
1. Each trial will last 1 minute. There will be at least a 30 second rest period between trials.
2. You will perform 3 trials of each cognitive task prior to moving on to the next task. There will be a 5 minute rest between cognitive tasks.
3. You will complete all testing on one limb (counterbalanced) prior to moving to the other limb.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
