The research aimed to assess the effect of various types of metro-rhythmic stimulation and the manner of their application on gait symmetry in healthy individuals.Research-related tests involved a group of 22 adults without locomotor function disorders.The test participants were divided into two equal groups: group 1persons, who were not informed how to behave after hearing sounds (stimulation), group 2 -persons instructed before a test to walk in the rhythm of music (stimulation).The tests of locomotor functions were performed using a Zebris FDM-S treadmill.All of the tests involving sound stimulation were performed for a preferable gait velocity.The analysis involved a change in the index of stepping time symmetry and the length of a step during gait with various types of sound stimulation (arrhythmic stimulus, rhythmic stimuli at a different rate).It was demonstrated that short-term rhythmic sound stimuli at the rate equal to stepping frequency at a preferable gait velocity affected the symmetrisation of stepping time in healthy adults, regardless of whether they had been informed how to react to stimulation.A short-term effect of the RAS on the symmetry of step length was not observed.
