Automatic nerve conduction velocity measure system

The authors developed an automatic measurement system for peripheral nerves. The system has two sections, a nerve electric response acquisition and synchrony section, which was implemented with a nerve stimulator, an amplification system and an optoelectric isolation system interfaced to the 2BOh PC address with an ADC and a PPI 8255. A second section consists of an acquisition, data processing and display program. This program controls the data of the patient and the type of study. The complete system is user friendly and the data (latency signals) are stored in ASCII format so that they can be analyzed by another signal processing software. After the user has made the stimulation, the program shows the acquired data and its latency time so this test can continue or begin again if the user wants to. This system is a very useful tool to detect neuropathies and the reinervation degree. The system was developed with “C” language for transportability
