Auditory cueing enhances gait in parkinsonian patients. Our aim was to evaluate its effects on spatiotemporal (stride length, stride time, cadence, gait speed, single and double support duration) kinematic (range of amplitude of the hip, knee and ankle joint angles registered in the sagittal plane) and kinetic (maximal values of the hip and ankle joint power) gait parameters using three-dimensional motion analysis. Eight parkinsonian patients performed 12 walking tests: 3 repetitions of 4 conditions (normal walking, 90, 100, and 110% of the mean cadence at preferred pace cued walking). Subjects were asked to uniform their cadence to the cueing rhythm. In the presence of auditory cues stride length, cadence, gait speed and ratio single/double support duration increased. Range of motion of the ankle joint decreased and the maximal values within the pull-off phase of the hip joint power increased. Thus, auditory cues could improve gait modifying motor strategy in parkinsonian patients.
