In this research two kinds of stimulation electrodes were compared in motor nerve conduction study: needle electrodes used in human medicine and electrodes made of injection needles connected to the stimulator via alligator-type electrodes. A study was conducted in 22 mixed-breed dogs. The resulting values of the potential amplitudes of the stimulus, the parameters of the complex muscle potentials, and the motor nerve conduction velocity were statistically compared. There was no statistical difference between the parameters obtained with the two types of stimulation electrodes. The results of our research constitute a basis for improving present-day procedures, improving aseptic procedures, reducing tissue trauma during research and lowering research costs due to the introduction of injection-needle electrodes and their benefits into the study of motor nerve conduction in animals.

The gait is a form of human and animal locomotion on land by using limbs. The study assessed functional recovery after end to side and side to side neurorrhaphy the ventral branches of the C5 and C6 spinal nerves to the C7 spinal nerve on the rabbit brachial plexus. Gait statistical analysis showed significant differences between the control group versus the end-to-side and side to side neurorrhaphy groups, in opposite to the comparison between the two experimentals groups. Gait analysis results corresponded with the histomorphometric results. The results indicate the potential use of gait analysis for the assessment of the recovery of nerve function.

The aim of our study was to analyze the anatomy and surgical approach of the rabbit brachial plexus. The research included 18 rabbits. The rabbit seems to be a good experimental model for spinal nerves injury, especially for the C5 and C6 segments. The anatomical structure of the rabbit’s brachial plexus is similar to the human brachial plexus. The structure of the rabbit C5 and C6 segments is analogous to the human structure. The spinal nerves of the C5 and C6 segments in the rabbit are wide and long enough for microsurgical procedures.

This paper discusses 28 canine patients subjected to low-field magnetic resonance imaging (MRI) of the spinal cord for neurological indications. The authors describe and compare the used MRI sequences with an indication of the most effective sequences in MRI examinations that require short scanning time. The most effective sequences supporting a quick diagnosis of spinal diseases in dogs were SE (spin echo), FSE (fast spin echo) and 3D HYCE (hybrid contrast enhancement).
