TY - JOUR AU - A. L. Dunn , A. L. Bennett , and A. R. McIntyre AB - i’tz Mm’ A. L. DUNN, A. L. BENNETT AND A. R. MCINTYRE, From the Department of Physiology and Pharmacology, University of Nebraska, College of Medicine, Omaha, Nebraska describes a method whereby the electrical activity associated with denervated muscle in man can be studied at the bedside with the use of minimal apparatus and without the necessity of electrostatic shields. The apparatus and methods used and the equipment employed in testing the method together with sample obtained from laboratory animals and from man are presented. The limits of usefulness and the degree of accuracy obtainable under hospital conditions are demonstrated and discussed. The apparatus used permits permanent photographic records to be obtained either directly from the fibrillating muscle or indirectly from the wire ; such records are compared. When the frequencies and amplitude of prolonged electrical activity were under study, permanent records were made on bromide paper. When detailed studies of the wave form of single action potentials were required permanent records were made on 35 mm. film. It should be emphasized of patients only the electrode, one amp1 ifier, the that in the examination speaker and the wire recorder need be used. These are readily portable and can TI - A Method For Recording Electromyograms in Man JF - Journal of Applied Physiology DA - 1948-11-01 UR - https://www.deepdyve.com/lp/the-american-physiological-society/a-method-for-recording-electromyograms-in-man-AMXogQw6fS VL - 1 IS - DP - DeepDyve ER -
