| Popis: |
Conduction velocity of the fastest fibres in sensory nerves (SCV), amplitude and shape of the sensory evoked potentials (SEPs) were studied in 94 normal children aged 5 days up to 15 years. Surface electrodes were used both for nerve stimulation and sensory evoked potential recording. Normal minimal value in young adults is reached between 2 and 4 years of age, earlier in the proximal segment of the nerve (wrist-elbow) than in the distal segment (digit-wrist). Amplitude of the median SEP at the wrist increases about 155% during the first 2 years of life; this increase becomes more progressive and moderate from 2 to 15 years of age. At the elbow, the SEP has a smaller amplitude and is made of two separate peaks in 80-100% of the children between 6 months and 10 years of age. The presence of those two separate components lends substance to the view that there are two groups of fibres with different degrees of maturation. Methodology and results are discussed along with previous data from the literature. |
