Surface electromyography (EMG) and muscle sonography both facilitate the detection of @entity2901 . This study was conducted to evaluate the prevalence of @entity2901 in 10 lower extremity muscles in 58 subjects 47 +/- 18 years of age without and 54 @entity1 52 +/- 15 years of age with various @entity4094 (3 with @entity5442 , 15 with @entity4681 , 22 with acquired and 11 with @entity1897 ( @entity1897 ), and 3 with @entity8019 ). When each muscle was screened by means of myosonography for 10 seconds, @entity2901 were found in up to 8 muscles in 11 control subjects (19%) and in up to 10 muscles in 41 @entity1 (76%). Within the same recording period surface EMG revealed @entity2901 in 5 control subjects (9%) and 30 @entity1 (56%), whereas during a recording time of 20 minutes @entity2901 were detected in 55 (95%) control subjects and all @entity1 . An amplitude of 400 microV proved to be the optimum cutoff between @entity2901 for healthy subjects and @entity1 with @entity4094 (accuracy, 74%). Myosonography allowed differentiation of both groups with an accuracy of 79%. Surface EMG was more liable to artifacts than myosonography. The average interval between subsequent @entity2901 cannot be used to differentiate @entity1 with acquired and hereditary @entity305 and with @entity4681 . Long-term surface EMG recording indicates @entity2901 to occur in almost all @entity1 with @entity4094 and the vast majority of healthy subjects. Muscle ultrasonography was more convenient and reliable than surface EMG in differentiating @entity1 and healthy subjects.
