The Effect of RAS on Individuals With Total Hip Replacement and Hip Revision Surgery

Abstract

Abstract The purpose of this study was to investigate whether individuals receiving Rhythmic Auditory Stimulation (RAS) during gait training showed statistically significant differences in cadence, stride length and velocity compared to those who only received conventional gait training. Six eligible subjects from three facilities in the Midwest and Southwest agreed to participate, with three assigned to the experimental group that received RAS and three assigned to the control group that did not receive RAS. The experimental group did have higher means for cadence, stride length and velocity, but variability in the data made statistical analysis of the data undesirable. An outlier in the experimental group with extremely high cadence, stride length and velocity skewed the data considerably so no statistically significant differences were found between the experimental and control groups. The number of days subjects spent in rehabilitation appeared to be correlated very closely with their gait parameters. Subjects with more days of rehabilitation had higher cadence, stride length and velocity regardless of whether they were in the experimental or control groups. Implications for future research are discussed.
