摘要

在164名不同年龄组的受试者中，我们研究了三块手部肌肉（APB=拇短展肌；FDI=第一骨间背侧肌；ADM=小指展肌）的神经生理学指数（NI）（[CMAP振幅/远端运动潜伏期]*[F波频率]；CMAP=复合肌肉动作电位）。计算基于CMAP幅度（SHI_CMAP）和NI（SHI_NI）的分割手指数（[APB CMAP幅度或NI*FDI CMAP幅度或者NI]/[ADM CMAP幅度or NI]）。所有这些神经生理学测量结果在不同年龄组之间存在差异（p

Exploring the split hand phenomenon with the neurophysiological index

In 164 subjects of different age groups, we studied the neurophysiological index (NI) ([CMAP amplitude/Distal motor latency] *[F-wave frequency]; CMAP=compound muscle action potential) for three hand muscles (APB= abductor pollicis brevis; FDI= first dorsal interosseous; ADM= abductor digiti minimi). A split hand index based on CMAP amplitude (SHI_CMAP) and NI (SHI_NI) were calculated ([APB CMAP amplitude or NI * FDI CMAP amplitude or NI]/[ADM CMAP amplitude or NI]). All these neurophysiological measurements differed between age groups (p<0.001). Hand muscle NIs, as well as SHI_NI and SHI_CMAP were age dependent. This may be relevant for diagnostic purposes in motor neuron diseases.

期刊介绍： Neurophysiologie Clinique / Clinical Neurophysiology (NCCN) is the official organ of the French Society of Clinical Neurophysiology (SNCLF). This journal is published 6 times a year, and is aimed at an international readership, with articles written in English. These can take the form of original research papers, comprehensive review articles, viewpoints, short communications, technical notes, editorials or letters to the Editor. The theme is the neurophysiological investigation of central or peripheral nervous system or muscle in healthy humans or patients. The journal focuses on key areas of clinical neurophysiology: electro- or magneto-encephalography, evoked potentials of all modalities, electroneuromyography, sleep, pain, posture, balance, motor control, autonomic nervous system, cognition, invasive and non-invasive neuromodulation, signal processing, bio-engineering, functional imaging.
