Improving hand function after stroke

RESEARCH STUDY

Stroke often affects both our ability of our hands to feel and our ability to contract muscles. Sensory and motor functions are tightly linked. Yet, most rehabilitation strategies aimed at regaining dexterity after stroke largely focus only on motor recovery.

We have previously found that some stroke patients have a disorganised touch perception map. When a patient is touched in one location on the hand while their eyes are closed, they feel it in some other location.  There is little awareness of this condition, and it is generally not detected during routine neurological examination as even patients themselves are not aware of it.

Our recent study revealed that it is possible to correct this scrambled map, leading to improved motor functioning. This new evidence means that we can now focus on creating new rehabilitation strategies that can help patients to regain normal sensation and fine motor skill after a stroke.

'I've got the best job for you dad. Your shaky arm will be perfect for it!'

Children… honest and insightful. Their innocence warms the heart. But what words do you use to explain to a child that daddy has an incurable brain disease? What words tell them that in time he may not be able to play football in the park, let alone feed himself? What words help them understand that in the later stages, dementia may also strike? Aged just 36, this was the reality that faced Steve Hartley. Parkinson's disease didn't care he was a fit, healthy, a young dad and devoted husband. It also didn't seem to care his family had no history of it. The key to defeating Parkinson's disease is early intervention, and thanks to a global research team, led by NeuRA, we're pleased to announce that early intervention may be possible. Your support, alongside national and international foundations Shake it Up Australia and the Michael J Fox Foundation, researchers have discovered that a special protein, found in people with a family history of the disease increases prior to Parkinson’s symptoms developing. This is an incredible step forward, because it means that drug therapies, aimed at blocking the increase in the protein, can be administered much earlier – even before symptoms strike. The next step is to understand when to give the drug therapies and which people will most benefit from it. But we need your help. A gift today will support vital research and in time help medical professionals around the world treat Parkinson’s disease sooner, with much better health outcomes. Thank you, in advance, for your support.
