Two-segment sural nerve conduction measurements in polyneuropathy.

Sensory conduction velocity of the sural nerve was measured in 50 normal subjects and 100 consecutive patients with suspected or established diagnosis of peripheral neuropathy. The sensory action potential was recorded by the orthodromic technique for the distal and the proximal segments. In the patient group, sensory conduction of the proximal segment appeared to be more consistent and easier to carry out as compared to the distal segment. Measurements of the latter segment alone could sometimes be misleading. Some practical points acquired from our experience with this method that allow considerable reduction of the examination time and the patients's discomfort are reported.

The actioculographic monitor of sleep.

The actioculographic monitor (AOGM) is a newly developed, flexible system for sleep recording using three criteria: eye movements, body movements, and submental electromyogram. The signals are recorded on a four-channel Medilog casette tape and displayed by a mingograph at very low speed. The record is then scored after certain criteria for stages wake, nonrapid eye movement, and rapid eye movement sleep. High statistical correlations were obtained when scoring of the AOGM was compared to scoring of standard polygraphic sleep recordings.

Practical application of patterned visual evoked responses in multiple sclerosis.

Pattern reversal visual evoked potentials (VEP) were studied in a control group of 72 subjects and in 60 patients with multiple sclerosis. The recording system consisted of a visual stimulator for pattern production on a commercial TV connected to an EMG machine for displaying and averaging of the response. The normal values of latency, the upper limit of normality and right-left differences in our control group were compared with those given by different authors. Likewise a comparison of the positive VEP results in MS was carried out. The reasons for the variability of results were briefly discussed and the importance of control studies for each laboratory starting VEP recording was stressed. This test can easily be carried out in every clinical neurophysiological laboratory and it provides an excellent and rapid technique for the investigation of patients with suspected multiple sclerosis.
