A New Brain-Powered Computer Game Could Help Stroke Survivors Regain Arm Movement.

Researchers at Queen’s University Belfast are launching a new study that could change how stroke rehabilitation is approached—by using a wireless, brain-powered computer game to help survivors regain arm movement.

The research team from the University’s School of Psychology is inviting 50 stroke survivors to take part in a one-year project testing a novel form of rehabilitation that combines neuroscience and gaming.

 The approach centres on using brain signals to control a computer game, even if the user is unable to physically move their arm.

Stroke remains one of the leading causes of adult disability in Northern Ireland, and for those who do survive, up to 80% face arm or hand weaknesses. As a result, tasks such as getting dressed, cooking, and writing are made much more difficult.

Brains are adaptable through a process known as neuroplasticity; other parts of a person’s brain can take over lost functions, and it can be very successful when the correct kind of rehabilitation is used.

With this in mind, Queen’s researchers from the University’s School of Psychology are kickstarting a one-year-long project using this new method.

Dr Kathy Ruddy is one of the lead researchers of this project, explains how the study will work: “We are looking for 50 stroke survivors to take part in our new study. We will be asking them to wear a simple headset that reads brain activity while they imagine moving their affected arm.”

“The brain signals are picked up and used to control a computer game. This form of “motor imagery” activates the same brain areas as real movement, and it may help keep these body parts healthy and active after a stroke, even when actual movement isn’t yet possible,” added Dr Ruddy.     

This technique, called motor imagery, is already used in some rehabilitation programmes, but the Queen’s team aims to make it more engaging and accessible through the use of computer games.

The hope is that even if physical movement is not yet possible, imagining movement can help preserve, and eventually, rebuild neural connections involved in controlling the arm.

The project is funded by Northern Ireland Chest Heart & Stroke (NICHS), a charity that works to prevent strokes and care for those who have experienced strokes.

As part of the study’s launch, an information event will be held at Riddel Hall, Stranmillis, on Thursday, 7 August from 11 am to 3 pm. Stroke survivors, their carers, and healthcare professionals are invited to attend.

The event will offer an opportunity to learn more about the research and speak directly with the researchers.

While the idea of controlling a game with your mind might sound futuristic, it’s grounded in well-established neuroscience. By capturing and using those signals to interact with a computer, the brain is encouraged to stay active, even when the body cannot yet follow.
