Presented by Professor John Marshall, Institute of Neurology, University of London. Produced by Trevor A Scott. Made by University of London Audio-Visual Centre at the Institute of Neurology in association with the British Postgraduate Medical Federation.

This video is one of around 310 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and early 1980s, thus constituting a contemporary medical-historical archive of great interest.

Segment 1 The opening scene shows a seated woman. The camera pans in to reveal the tremor of her right hand. Marshall describes how this kind of involuntary movement is a sign of neurological disorder. He refers to a chart detailing the classification of different types of involuntary movement.
