As many as 33 children operated on for congenital meningocele of the inferior parts of the spine were subjected to clinicoelectromyographic studies. Alterations seen in the amplitude of the maximum M-response serve as one of the objective indicators of the degree of neuromuscular lesions. According to the magnitude of that amplitude, the patients were distributed into 4 groups: I /0 mV/, group II /0-1 mV/, group III /1-6 mV/, group IV /more than 6 mV/. The F wave reflecting the status of antidromic excitability of the spinal motoneurons is only recordable in groups III and IV of the patients (65%), with the magnitude of the maximum M-response being over I mV. H-reflex, as an indicator of reflex excitability of the motoneurons, is the most labile electromyographic parameter which is only recordable in some patients belonging to group IV, constituting 12% of the total number of the examined patients. |
