To investigate the effect of visual (VC), auditory (AC) and the association of both cues (VAC) during gait in Parkinsons disease (PD) subjects in ON. METHODS: The design was a repeated measures study. Data was obtained using the movement analysis system Qualysis Pro-reflex. The General Linear Model, the Generalized Estimating Equations Model and multiple comparisons with Bonferroni were used in the analysis. The significance level was p<0.05. RESULTS: Ten PD subjects, male and female, participated in the study. Velocity and stride length increased in all conditions when compared to no-cue condition; AC increased cadence and VC decreased cadence; the percentage of the stance phase decreased in VC and VAC (p<0.02). During initial contact, AC generated the smallest plantar-flexion angle and in all cueing conditions the hip flexion angle increased (p<0.04). During weight acceptance, VC and VAC increased the plantar-flexion angle while AC decreased the angle (p<0.01). During terminal stance, VC and VAC generated higher dorsiflexion angle (p<0.01). The hip extension angle was elevated in all cueing conditions (p<0.01), with the highest extension occurring with VAC, followed by VC. During preswing, VAC generated the highest plantar-flexion angle and VC the highest hip extension angle, followed by VAC (p<0.01). During terminal swing, AC and VC generated less plantar flexion angle, VC and VAC less knee flexion angle and all cueing conditions generated higher hip flexion angle (p<0.01). CONCLUSION: All cueing conditions compared to walking with no-cue improved the gait pattern of the PD subjects. However, VAC condition showed better results.
