Research will explore whether game can help stroke survivors recover movement

A new study is investigating whether a brain-controlled computer game can help stroke survivors recover movement in their arms.

Participants will wear a wireless headset that records brain activity as they imagine moving their affected arm, with those signals used to control a computer game.

The research, led by Queen’s University Belfast (QUB), is recruiting around 50 people who have had a stroke. It aims to harness neuroplasticity – the brain’s ability to reorganise and allow other regions to take over lost functions.

Many stroke survivors find everyday tasks such as dressing, cooking or writing extremely difficult. Different types of rehabilitation, including game-based approaches, can offer support.

Dr Kathy Ruddy, a neuroscientist leading the research, said: “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.”

The project is funded by Northern Ireland Chest, Heart and Stroke.

Dr Ruddy added: “By incorporating different types of neural signals into brain-controlled games, the team can train human participants to modify specific aspects of their neurophysiological function.”

Rodney Hamilton, 67, from Dundonald, had a stroke aged 46 and lost movement in his arm and hand.

Once a keen guitarist, he told BBC News NI he misses the music.

He said the experience of playing the video games has been enjoyable and encouraged others to join the study.

He said: “I would encourage others to take part in the project.

“It’s very, very good.”

The team at QUB said the research is giving hope to people whose movement or speech remains affected after stroke.
