In Kathy Louise Ruddy’s lab at Trinity College Institute of
Neuroscience, brain-computer interfaces (BCI) are used to study the
brain, improve aspects of human behavior, and generate evidence of
the efficacy of a new technique in stroke rehabilitation.
Tune in to learn:
- How electroencephalography and transcranial magnetic stimulation (TMS) BCI techniques work
- Why the current gold standard in stroke rehab (constraint-induced movement therapy) only works for some people, and how TMS can fill the gap
- When a new stroke rehab therapy could be brought to the clinic
For people who are recovering from stroke, there’s a new
therapeutic technique being researched that could hold great
promise: transcranial magnetic stimulation (TMS). TMS is a type of
BCI that magnetically stimulates the brain to cause a response
(i.e. movement) in the muscle. These responses are recorded and
used as feedback for the BCI, which enables the user to see and
control those responses using various strategies.
For example, if the user wants to increase the intensity of the
muscle response in a finger, they might imagine forcibly pushing an
object with that hand; if the user wants to decrease the intensity
of the muscle response, they might imagine that their hand is cold
or detached from the body. The hope is that when this is applied to
the affected limb of a stroke patient, it will build and strengthen
the neural pathways that were used to trigger movement in the
muscle prior to the stroke, thereby increasing function and use of
the affected limb.
Ruddy discusses all the details of this technique and more, including past and upcoming research, results and feedback from research subjects, the use of electroencephalography to train users to control their brainwaves/neural oscillations, and what the near and long-term goals look like for Ruddy’s team.
