“…In support of this hypothesis, it was shown previously that the presence of external cues led to less-efficient writing movements in healthy elderly compared with young adults. 56 More recently, Vitorio et al 57 showed that in gait, PD patients and healthy controls used the same strategy to capture visual information from visual cues. 57 Although PD patients and controls showed comparable behavior during both internally and externally triggered movements in a computerized choice reaction time task, 56 there were great differences at the neural level.…”

“…57 Although PD patients and controls showed comparable behavior during both internally and externally triggered movements in a computerized choice reaction time task, 56 there were great differences at the neural level. 57 Results showed increased functional connectivity between the dorsolateral prefrontal cortex (PFC) and lateral premotor cortex (PMC) in patients compared with controls only in the externally guided condition. These results provided a strong indication for a compensatory role of the PFC-PMC connection, which allowed patients with PD to maintain task performance at a level similar to that of healthy elderly individuals during external cueing.…”

“…It is well accepted that visual cues are critical for gait improvement for people with PD (Azulay, Mesure et al 1999; Lebold and Almeida 2011; Lewis, Byblow et al 2000; Morris, Iansek et al 1994; Spaulding, Barber et al 2013; Vitorio, Lirani-Silva et al 2014). These studies used traditional cueing methods such as stripes placed on the ground.…”

Veering in hemi-Parkinson’s disease: Primacy of visual over motor contributions

et al. 2015

Veering while walking is often reported in individuals with Parkinson’s disease (PD), with potential mechanisms being vision-based (asymmetrical perception of the visual environment) or motoric (asymmetry in stride length between relatively affected and non-affected body side). We examined these competing hypotheses by assessing veering in 13 normal control participants (NC) and 20 non-demented individuals with PD: 9 with left-side onset of motor symptoms (LPD) and 11 with right-side onset (RPD). Participants walked in a corridor under three conditions: eyes-open, egocentric reference point (ECRP; walk toward a subjectively perceived center of a target at the end of the corridor), and vision-occluded. The visual hypothesis predicted that LPD participants would veer rightward, in line with their rightward visual-field bias, whereas those with RPD would veer leftward. The motor hypothesis predicted the opposite pattern of results, with veering toward the side with shorter stride length. Results supported the visual hypothesis. Under visual guidance, RPD participants significantly differed from NC, veering leftward despite a shorter right- than left-stride length, whereas LPD veered rightward (not significantly different from NC), despite shorter left- than right-stride length. LPD participants showed significantly reduced rightward veering and stride asymmetry when they walked in the presence of a visual landmark (ECRP) than in the eyes-open condition without a target. There were no group differences in veering in the vision-occluded condition. The findings suggest that interventions to correct walking abnormalities such as veering in PD should incorporate vision-based strategies rather than solely addressing motor asymmetries, and should be tailored to the distinctive navigational profiles of LPD and RPD.

“…Studies reveal that rhythmic cues help PD patients to replace typical automatic gait control with a more conscious and perhaps, more discreet movement, making walking easier. In this case, increased cortical activity observed during directed movement would compensate for striatal dysfunction (14). The use of this technique is associated with altered patterns of neural activity, more specifically, with improved activity in the lateral premotor cortex (15).…”

Comparison of three physical therapy interventions with an emphasis on the gait of individuals with Parkinson’s disease

et al. 2017

Introduction: Gait impairments are one of the earliest signs reported by patients with Parkinson's disease (PD) and cause an increased number of falls and decreased quality of life among these patients. Objective: To compare the effectiveness of three physical therapy interventions using Rhythmic Cues (RC), Swiss Ball (SB) and Dual Task (DT), with an emphasis on gait treatment (step and stride length, duration and velocity), in individuals with PD. Methods: Quasi-randomized clinical trial addressing a sample composed of 45 individuals assigned to three groups. The individuals were assessed before and after the intervention protocol using the following: Modified Hoehn and Yahr Scale (HY), Unified Parkinson's Disease Rating Scale (UPDRS), Footprint analysis, Video Gait analysis, and Timed Up and Go Test (TUG). The groups were homogeneous concerning age, HY and UPDRS. Statistical analysis was performed using SPSS, version 20.0. Results: Statistically significant differences were found in all the variables analyzed in the RC and SB groups when compared in the pre-and post-intervention. With the exception of the TUG variable, the DT group presented statistically significant differences in all the remaining variables. Conclusion: The three interventions were effective for the outcomes under study, but the SB group presented the greatest magnitude of
