Simultaneous measurement of conduction velocity in the neural sensory and motor fibers during segmental stimulation

The study concerned the method of investigation of upper extremity nerves which makes possible a simultaneous measurement of the conduction velocity in the motor and sensory fibres over the whole length of the nerve. Recording of responses was based on the use of surface electrodes which are safe, less painful for the patient, and provide sufficiently great responses without the necessity of using the averaging technique. Owing to simultaneous responses from the motor and sensory fibre from several stimulation sites along the nerve the localization of injury and its type are easier to establish. The method is less time-consuming than the conventional one and may be used by technicians.
