|Abstract:||Abstract We developed a summary score of data obtained from nerve conduction studies (NCS). The principle of such approach is that when a nonrandom trend to lower amplitudes or conduction velocities is present, it may be revealed by a summary nerve conduction score. In a group of normal subjects, peroneal, sural, ulnar, and superficial radial nerves were studied; age- and height-related F-wave and soleus H-reflex latencies were also examined. Z-scores of distal latencies, amplitudes, conduction velocities, F-wave latencies, and H-index were averaged in order to obtain three electroneurography (ENG) indices: a simple arithmetic (ENG index 1) and two weighted means (index 2 and index 3), assigning a double or triple weight to lower limb z-scores. Reference limits were established using multiple regression equations of ENG indices against age and height. This technique could be useful in providing a better cut-off between normal and diseased populations and in improving test-retest variability of NCS when follow-up studies are required.
