To establish age-related characteristics and normative values of F waves in healthy Chinese infants.
We studied median, ulnar and tibial nerves on one side distally in 229 healthy Chinese infants (108 males) ranging from 1 to 12 months old.
Minimal F-wave latencies (Fmin) showed a strong negative correlation to the age for median, ulnar and tibial nerves (P < 0.01) but no correlation to the height. Statistical analyses revealed a significant (P < 0.01) decrease of Fmin during the second month of life and no change (P > 0.05) thereafter. Dividing the infants into 1 month old (Group 1) and 2-12 months old (Group 2), normal values (Mean ± SD ms) of Fmin for tibial, median and ulnar nerves consisted of 23.38 ± 1.68, 17.19 ± 0.95 and 16.47 ± 1.06 for Group 1 and 21.42 ± 1.25, 14.50 ± 1.15 and 14.52 ± 0.90 for Group 2.
F-wave latencies shorten in the 2nd month of life and change little thereafter when age-related maturation counters the concomitant growth of the nerve length.
F waves can assess infantile neuropathies as a reliable measure, complementing the technically difficult conventional nerve conduction study in short limbs.
建立健康中国婴儿 F 波的年龄相关性特征和正常值。
我们研究了 229 名健康中国婴儿（108 名男性）一侧的正中神经、尺神经和腓总神经，年龄从 1 至 12 个月。
最小 F 波潜伏期（Fmin）与正中神经、尺神经和腓总神经的年龄呈强负相关（P<0.01），但与身高无关。统计学分析显示，Fmin 在生命的第二个月显著下降（P<0.01），此后无变化（P>0.05）。将婴儿分为 1 个月龄（第 1 组）和 2-12 个月龄（第 2 组），腓总神经、正中神经和尺神经的 Fmin 正常值（Mean±SD ms）分别为第 1 组 23.38±1.68、17.19±0.95 和 16.47±1.06，第 2 组 21.42±1.25、14.50±1.15 和 14.52±0.90。
F 波潜伏期在生命的第二个月缩短，此后随着与年龄相关的成熟与神经长度的同时生长相抗衡，变化很小。
F 波可以作为一种可靠的测量方法来评估婴儿神经病，补充了在短肢中技术上困难的常规神经传导研究。
