Question

What is interhemispheric inhibition?

Answer

The way I like to think about it, without getting too technical, is to think about the affected side of the brain as being bullied by the unaffected side. The unaffected side increases the activation because the affected side is damaged and has decreased activation. The unaffected side starts to take over some control of the affected side, and what that looks like clinically is the affected arm and hand are weaker and do not function as well. Meanwhile, the unaffected arm and hand get stronger contributing to that learned non-use phenomenon. If we do bilateral activities, are we clinically using both arms and hands equally? By doing that, are we stimulating the unaffected side, the bully of the brain? Or is it better to do a unilateral task so that you can try to increase activation of the affected side? There is a lot of discussion. I do not know the right answer to that right now. A big controversy is that most of our everyday tasks require both hands and both arms to use. Is it really feasible and realistic to just use one hand? Hope that explained it well enough.

Prior to her work in academia, she spent her career in St. Louis, Missouri at St. Anthony's Medical Center; Baltimore, Maryland at Johns Hopkins Bayview; and in Atlanta, Georgia at Emory University. She served as a project coordinator for numerous research studies at Emory University involving rehabilitation therapies for the neurologically compromised upper extremity, including constraint induced movement therapy, mental imagery, and use of robotic devices. She is the author of numerous peer-reviewed articles, and has presented nationally, internationally, and virtually for a a wide variety of audiences. She is also a Certified Brain Injury Specialist Trainer. Her dissertation and research area of interest is neurorehabilitation after stroke or head injury, specifically, contemporary approaches of neurorehabilitation, such as task oriented training, as well as outcome measures related to the neurologically involved population.
