It has been studied the answer to the LSI in migraine subjects (166) and with tension headache (198). Only in tree cases, which on migraine and two with tension headache, the answer given is anomalous to the LSI, with a frequency like those found in "normal" population.

In 100 subjects with Carpal Tunnel Syndrome (CTS) and any other illness, the conduction velocity of the radial sensory nerve (RSN) was studied on the hypothesis that, because of the relation with the tendon of the brachioradialis and extensor carpi radialis longus muscles, microtrauma can injure the RSN. In 13 patients, for a total of 15 limbs involved, the SCV is reduced less than 2.5 SD, in 5 the distal latency is prolonged and in 1 there is both a slowing of SCV and prolonged distal latency. The involvement of RSN is more frequent in the dominant hand. There is no relation between the severity of CTS and damage of RSN or between clinical and electrophysiological data. It therefore seems that the entrapment of RSN is quite frequent and can explain some symptoms and modify the therapy.
Supine and after standing F wave studies were performed in 22 healthy subjects, in 14 patients with L5 root compression and in 11 patients with low back pain. Unlike previous works, the latency of the F minimal wave, F maximal, F mean and F chronodispersion before and after standing are similar. It is possible that the positional changes of the F wave may be of clinical interest only in sub-groups of patients and the usefulness of further studies is stressed.
The acoustic P300 wave was elicited in 47 healthy subjects aged between 16 and 83 years. The neurophysiological data were correlated with scores from the State-Trait Anxiety Inventory Test in the X1 and X2 forms and with scores from the Middlesex Hospital Questionnaire. The amplitude of the N2 wave and the N2-P3 time recorded at Cz significantly correlate with the scores of the X1 and X2 tests. The results suggest that some personality features can slightly modify the acoustic P300 wave, but the significance of these changes remains uncertain.
The aim of this paper is to compare the potentials from the extensor digitorum brevis (EDB) with those from the tibialis anterior (TA) stimulating the peroneal nerve proximally and distally the fibular head in patients suffering of peroneal nerve palsy at the fibular head. In 8/30 limbs the electrophysiological studies were normal. According to electrophysiological findings the lesion was of demyelinating type in 6/22 patients, axonal in 8/22 and mixed in 8/22. In 12/22 limbs the abnormalities were found recording both for EDB and TA muscles; in 7/22 recording only from EDB and in 3/22 recording only from TA. Thus it is possible that motor fibers supplying the EDB and TA may be damaged differently and is useful evaluate both muscles.
