    EMG Waveforms: Video Companion to Electromyography and Neuromuscular Disorders. Edited by david c preston andbarbara e shapiro. (Pp 56, £55.00). Published by Butterworth Heinemann, Oxford, 2000. ISBN 0750672293.

    This is a well constructed video with plenty of examples of EMG phenomena of interest to the trainee clinical neurophysiologist. Some common and unusual examples are included which provide an opportunity to recognise them, particularly when they can sometimes be difficult to capture and demonstrate in the clinic.

    There are only a few minor areas of concern. It would be helpful to know some of the clinical background behind the various cases presented, which would probably help in the understanding and interpretation of the various abnormalities. On occasion, the EMG pictures seem to be slightly out of focus and future availability in a digital format might be more convenient. The accompanying booklet is essential (related to the authors' textbook, reviewed in an earlier edition of this Journal), and is required reading throughout the video. An auditory commentary may have been easier to follow. For future editions, a quiz type session at the end of the video might also be a useful training exercise.

    Despite these reservations, this is a good training video and I recommend it.
