Effect of Auditory and Visual Cues on Gait in Patients with Idiopathic Parkinson's Disease

Objective: To examine the effects of auditory and visual cues on gait in patients with idiopathic Parkinson's disease (IPD). Method: Patients were 16 persons with IPD, and controls were 14 age-matched healthy persons. Controls were allowed to walk at self-selected gait speed and patients walked at no, auditory and visual cues. Gait parameters were gained, and stride variability were measured at each gait trial. Results: In patients, cadence at visual cues was decreased compared with that of controls, no and auditory cues in the statistics. Walking velocity was decreased in all patients than controls, but there was no difference in each cues. Stri-de length at visual cues was increased compared with that of no and auditory cues, and increased to that of controls. Stride variability was decreased at visual cues compared with that of no and auditory cues, and decreased to that of controls. Conclusion: With the use of visual cues in patients with IPD, the cadence was decreased but stride length was increased and stride variability was decreased to the level of controls. Thus, visual cues could be one of the useful method for gait training in patients with IPD.
