“…This pattern consists of sharp spikes of short duration and polyphasic potentials which appear to originate from the synchronization of activity of fibers surviving close together within the motor unit. In a dystrophic process in a muscle or group of muscles, a significant decrease in duration of I to 3 msec must be found in a sufficient number of motor units [33].…”

Abstract. Electromyographic investigation ofdiaphragmatic muscles of Meuse-Rhine-Yssel cattle revealed a significant decreased duration of action potentials, while the number of polyphasic potentials was increased in four of seven cows. Histologically, the diaphragmatic muscles in all cows were affected severely, as characterized by variation in size of individual fibers, abundant vacuolar and hyaline degeneration with occasional fragmentation and phagocytosis, fiber splitting, apparent increase in internal nuclei, vesicular nuclei, chains of central nuclei, absence of regeneration, and proliferation of endomysial and perimysial connective tissue. Core-like structures seemed to be a hallmark of the disease. The intercostal muscles in all cows had core-like structures and some variation in fiber size; degenerative lesions did occur, but were less severe than in diaphragmatic muscles. In other skeletal muscles and cardiac muscles, core-like structures were present predominantly, indicating a generaIized muscle disorder. No lesions were detected in the peripheral or central nervous systems.The muscular alterations were classified as a progressive muscular dystrophy, with a suspicion of hereditary transmission. This dystrophy may be an important animal model.

Electromyographic findings were studied in 32 women and 7 men with progressive systemic sclerosis. Among the 14 patients in group 1, 7 had the CREST syndrome in an early stage while the 14 patients in group 2 had advanced CREST-type lesions. The 18 patients in group 3 had diffuse scleroderma with extensive visceral involvement. In all groups, the mean duration of single potentials was reduced and the percent of polyphasic potentials was above normal in groups 2 and 3. Distal muscles were more involved in group 1, and proximal muscles in group 2. In group 3, involvement of various muscles was nearly equal. Electromyographic changes correlated with the clinical condition of the patients. Overall, the findings in this study are similar to findings from other laboratories.Muscular changes associated with scleroderma can be demonstrated directly by electrophysiologic and histologic examinations and indirectly by biochemical studies, e.g., creatine phosphokinase (CPK) activity . Electromyography (EMG) has a special placeFrom the
