Concentric needle electrode electromyography was carried out and motor nerve conduction
measured in 35 infants suffering from myelomeningocele at a mean age of 5.1 hours.
Electromyographic signs of denervation were inconspicuous and the findings suggested
that a lesion of the upper motor neurone — with or without spinal shock — was more
important than one of the lower motor neurone. There was a highly significant reduction
in motor conduction velocity of lower limb nerves. It is postulated that this is due
to retarded myelination of lower limb nerves.
