Research Stroke is one of the leading causes of adult disability: two thirds of patients survive, but approximately 80% of stroke survivors lose some ability to use their arm and/or hand, which affects activities of daily living, such as eating, manipulating the oven knob, writing, etc.

Our goal is to induce long lasting improvement in such tasks by having patients perform systematic exercises adapted to their disability by performing motivating therapeutic video games. We have examined the main needs of chronic stroke patients, and developed simple rehabilitation tools to help them to gradually improve their hand function.

Clinical trials on chronic stroke patients showed a significant improvement of the motor function in both hand and arm (though only hand movements were trained), which maintained after the stroke. This project was initiated with the groups of Teo Chee Leong of NUS and Ted Milner of McGill.

We currently investigate training of reaching and manipulation for subacute stroke patients with collaborators at NHNN in London, and develop low-cost non-actuated sensor-based rehabilitation systems.
