“…After this interval, the subjects were instructed to walk three steps at a self-selected speed. In the dual-task condition, the previous procedures were repeated; however, the subjects were required to perform the Stroop test simultaneously, which consisted of naming the color used to print the name of a different color (Romann, Dornelles, Maineri, Rieder, & Olchik, 2012). The order of each condition (single-and dual-task) changed randomly, from individual to individual, to avoid a learning effect.…”

The authors aimed to compare the postural phase of gait initiation under single-task (gait initiation) and dual-task (gait initiation plus Stroop test) conditions in healthy subjects and in subjects with Parkinson's disease (PD) in the early stages (Hoehn and Yahr scale < 3). The postural phase of gait initiation was assessed through the centre of pressure in single and dual task in 10 healthy subjects and 9 with PD. The analysis indicated that in the early stages of PD, an additional cognitive task did not affect the displacement of the gait initiation. No significant effects occurred between the groups and within-subjects (p > .05). Also, no interaction was found between the groups and the conditions (single- and dual-task). Differences were found in the duration of the mediolateral postural phase (p = .003), which was higher in PD subjects than in healthy subjects. The findings suggest that subjects in the early stages of PD prioritize gait initiation, as their motor performance was similar to that of healthy subjects.

“…After this interval, subjects were instructed to sit, again without any kind of support and at a self-selected speed. In the dual-task condition, all the previous procedures were repeated; however, the subjects were required to perform the Stroop test during the performing of the STSTS sequence [28]. The test words in different colours were projected on a wall at eye level.…”

“…The MoCA test consists of eight fields: visuospatial, nomination, memory, attention, language, abstraction, deferred evocation and orientation. The performance of an individual is calculated by the addition of the scores obtained in each of the domains, and the maximum that can be reached is equal to 30 points [25] and [28]. For the evaluation of the postural control, the data from the force platform was acquired at a sampling rate of 1000 Hz [29].…”

An observational, analytical and cross-sectional study was performed. The sample 7 consisted of 9 individuals with PD and 9 healthy controls. A force platform was used to 8 measure the CoP displacement and velocity during the sit-to-stand-to-sit sequence. The 9 results were statistically analysed. 10Individuals with PD required greater durations for the sit-to-stand-to-sit sequence than 11 the controls (p<0.05). The anteroposterior and mediolateral CoP displacement were 12 higher in the individuals with PD (p<0.05). However, only the anteroposterior CoP 13 velocity in the stand-to-sit phase (p=0.006) was lower in the same individuals.14 Comparing the single-and dual-task conditions in both groups, the duration, the 15 anteroposterior CoP displacement and velocity were higher in the dual-task condition 16 (p<0.05). 17The individuals with PD presented reduced postural control stability during the sit-to-18 stand-to-sit sequence, especially when under the dual-task condition. These individuals 19 have deficits not only in motor performance, but also in cognitive performance when 20 performing the sit-to-stand-to-sit sequence in their daily life tasks. Moreover, both 21 deficits tend to be intensified when two tasks are performed simultaneously.

The Influence of a Cognitive Task on the Postural Phase of Gait Initiation in Parkinson’s Disease: An Electromyographic-Based Analysis

et al. 2017

The aim of this study was to compare postural control strategies during gait initiation in single-and dual-task conditions in individuals in early stages of Parkinson´s Disease (PD).The activation timing of tibialis anterior occurred significantly later in the individuals with PD than in the controls (p=0.05), and a significant interaction between the groups, conditions and limbs was found (p=0.027). Differences between the single-and dual-task conditions were observed for the activation timing of the tibialis anterior (p=0.042) and for the magnitude of soleus (p=0.007), with lower values for the dual-task condition. Furthermore, not all the individuals followed the previously reported pattern of soleus inhibition followed by tibialis anterior activation. The duration of the mediolateral displacement of the centre of pressure was longer in the individuals with PD than in the controls (p=0.019). The anticipatory postural adjustments during gait initiation are impaired in PD and are expressed by an activation failure of tibialis anterior in both single-and dual-task conditions. Hence, it is important that during rehabilitation, intervention should concentrate on the TA.
