摘要
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.
