“…Our results on the diagnostic yield of neurophysiological examinations and muscle biopsy in neuromuscular disease agree with those reported by other laboratories [4,6,10,12,13]. The concordance of the two techniques reaches 94% and is highest in neuropathies.…”

The diagnostic value of EMG and muscle biopsy has been compared with muscle CT in 53 patients with neuromuscular diseases. CT concordance with clinical diagnosis was found in 62% of myopathies and was highest in Duchenne PMD and scapulo-peroneal myopathy and very low in metabolic and inflammatory myopathies. In neurogenic diseases muscle CT agreed with clinical diagnosis in 63% of patients: the highest concordance was found in acquired polyneuropathies.

“…7 Black et al reported over 90% concordance of needle EMG and histopathological findings in a study of 105 patients. 1 These investigations seem to prove a high sensitivity of the needle EMG, but without a control group of healthy subjects, which was missing in all studies, a statement about specificity or positive prediction is not possible.…”

“…The complex repetitive discharges seen on electromyography in the 3 dystrophin-deficient animal models 10,13,104 and, to a lesser extent, in DMD 105 offer an additional mechanism to account for muscle hypertrophy. Sustained electrical activity (myotonia) and muscle contractions associated with chloride and sodium channelopathies can lead to dramatic muscle hypertrophy in the nondystrophic myotonias.…”
