In order to compare right-leg and left-leg dominant subjects in the gait initiation task, we performed symmetry on angles (around 0° or 180° considering cases) in the frontal and horizontal plane and on EMGs (inversion of left and right EMGs) of left-leg dominant subjects.
Executive function impairments manifest in a number of different forms, such as difficulty in task planning and initiation, task switching, and organization or integration of cognitive skills [ 19, 20], suggesting that an executive impairment might underlie the deficit of aMCI individuals on the PM component of PM tasks.
No statistically significant associations were observed between Full Scale IQ and number of non-responses (Spearmans Rho = 0.22; p = 0.12), mean response times (Pearsons r = 0.29; p = 0.11) or intra-individual co-efficient of response time (Pearsons r = −0.01; p = 0.6) on the motor initiation task.
The relationship of some part of the most anterior regions of the aI to task-level control signals (i.e., the task initiation and task maintenance signals) also remains ambiguous as to its location.
Similarly, PD subjects show an increased force and velocity of initial steps during gait when presented with a cutaneous "go" signal during a step initiation gait task [38].
First, consistent with the above qualitative interpretation of Figure 5A, all 33 ROIs showed a positive temporal shift (i.e., a later peak for longer RTs; all ps<.05), consistent with the notion that a general delay in the initiation of task-related processing is one contributor to longer RTs.
The activity in the fronto-parietal control system has been attributed to initiation of task performance, and adjustment of cognitive control on a continuing trial-by-trial basis.
For residents newly initiated on warfarin therapy, survey respondents were asked to report three categories of tasks: initiation (activities or tasks to start patients on warfarin), monitoring (INR testing and monitoring for bruising), and management (activities or tasks related to monitoring documentation, patient education, and physician/pharmacist consultation).
Within the initiation period, HR tasks were fixed, and the more prospective cases (Cases A, B and C) appointed HR task forces to design short-term HR trainings, covering identification of target groups, designing training programs or modules and fixing the delivery, including decisions about the provider (internal/external).
Figure 3 presents the activity of two leg muscles, the right tibialis anterior and the left gastrocnemius, and the trajectory of the center of pressure (COP) in the horizontal plane, for gait initiation and walking tasks in one subject (right-leg dominant).
