Research project: Quantitative measures of impairment and how they relate to function in the older adult post-stroke, Dunhill Trust / British Geriatric Society

Currently Active: 

Following a stroke many people have difficulty moving their arm and hand and this has a great impact on their independence and ability to perform everyday tasks. People usually experience weakness, spasticity (inappropriate over-activity in some muscles), loss of control of movement and stiffness. In this project we are identifying effective ways to measure these different components and examining how they relate to loss of function. To do this we have built a rig in which each of these components can be measured in a reliable, objective and valid way.

This study is a collaborative project between the FoHS (RHT Research Group) and ISVR. In it we are investigating the relationship between impairment and functional ability associated with stroke affecting the upper limb. A wrist rig has been designed and built in which forces, ranges of movement, motor control and muscle activation patterns can be examined and related to functional abilities. Using state of the art signal processing techniques, novel indices are being derived and tested to provide valid and reliable measures that will be provide unprecedented information for clinicians about specific impairments, their relationship to function and how they change over time.

Our long-term aim is to design and validate a system that could be used clinically to assist in clinical decision-making and evaluation.
