Electromyography reveals the etiology of floppy infant in developing country

Background. Floppy infants are correlated with the extensive differential diagnosis. It can make diagnostic approach be-come more challenging. Case report. We report a 10-months-old infant referred from Pediatrician to electromyography (EMG) laboratory presenting with floppy and developmental delays. The central and motor neuron manifestations also increased of CPK levels bring ambiguity for the diagnosis. EMG may distinguish the cause from myopathy, anterior horn cell, neuromuscular junction (NMJ) or central origin when genetic testing is not routinely done in developing country. Conclusion. EMG helps clinician to distinguish the diagnosis of floppy infant.
