The aim of the experiments was to check the validity of the method of
contact electrodes for studying overground locomotion in the rat. The
basic indices of locomotion, obtained in 7 intact rats with at least 1
00 steps recorded in each, were analysed and compared with those descr
ibed by other authors using different methods of movement recording. I
t was found that the method of contact electrodes gives reproducible a
nd reliable results and may thus be used in further experiments of rat
locomotion after CNS lesions.
