Investigators in Belgrade, Serbia, and Newcastle upon Tyne, UK, reviewed the literature (Ovid Medline, 1948-2012) for citations on repetitive nerve stimulation (RNS) and single fiber electromyography (SFEMG) in children. Five articles contained data on 48 normal children studied with RNS and only 1 article with data on SFEMG in 20 normal children were located. Significant differences in the response to RNS in children compared to adults were identified, emphasizing the need for age appropriate normal values. 
COMMENT. The late Dr Ingrid Gamstorp published extensively on normal conduction velocities of peripheral nerves in infancy, childhood, and adolescence: [2, 3]. Also, in  Dr Gamstorp's sensory nerve conduction research was conducted while a visitor in the Division of Neurology, 1964-5, at then Children's Memorial, now Ann & Robert H. Lurie Children's Hospital of Chicago.
