Orna Rosenthal, Chris Miall (School of Psychology) and David Punt (School of Sport, Exercise and Rehabilitation Sciences) were recently awarded an MRC Confidence in Concept grant of £98,000 to develop their methods for mapping upper limb motor performance after stroke.

This work follows on from an MRC funded study in which the team showed a significant benefit for individualised rehabilitation of upper limb movements in chronic stroke patients. The study used robot-assisted rehabilitation, but uniquely added an algorithm to select the training movements for each patient, based on a ‘map’ of their performance.

The new CiC award will extend this work, testing larger numbers of stroke patients, and will address the hypothesis that the patients can be clustered into a small number of groups with similar impairments, so speeding up the selection of their rehabilitation training.
