Abstract

Scientists in the Experimental Psychology Department study patients with a variety of motor difficulties, including apraxia - a condition usually following stroke which involves lack of control of a patient over their hands or fingers. Diagnosis and rehabilitation are traditionally carried out by Occupational Therapists. In recent years, computer-based tests have been developed in order to remove the human subjectivity from the diagnosis, and in order to enable the patient to carry out a rehabilitation programme at home. One such test involves users being asked to carry out static gestures above a Leap Motion sensor, and these gestures being scored according to a variety of criteria. A prototype has been constructed to gather data, and some data has been gathered from a few controls and patients. In order to deploy this as a clinical tool into the NHS, there is need for a systematic data collection and analysis tool, based on machine learning algorithms to help classify the data into different categories. Algorithms are also needed in order to classify data from stroke patients, and to assess the degree of severity of their apraxia. Also, the graphical user interface needs to be extended to give particular kinds of feedback to the patient in the form of home exercises, as part of a rehabilitation programme.

This project was originally set up in collaboration with Prof Glyn Humphreys, Watts Professor of Experimental Psychology. Due to Glyn's untimely death a new co-supervisor needs to be found in the Experimental Psychology Department. It is unrealistic to assume this project can run in the summer of 2016.
