“…A similar dual-task induced conservative behaviour was recently reported in the context of an obstacle circumvention study involving individuals with Parkinson’s disease and age-matched healthy individuals [ 77 ]. However, individuals from the m/sTBI group in the present study seemed instead to exert a riskier collision avoidance behaviour, as they failed to modulate the onset of trajectory deviation and adopted smaller obstacle clearances under dual-task conditions.…”

Background Individuals with a moderate-to-severe traumatic brain injury (m/sTBI), despite experiencing good locomotor recovery six months post-injury, face challenges in adapting their locomotion to the environment. They also present with altered cognitive functions, which may impact dual-task walking abilities. Whether they present collision avoidance strategies with moving pedestrians that are altered under dual-task conditions, however, remains unclear. This study aimed to compare between individuals with m/sTBI and age-matched control individuals: (1), the locomotor and cognitive costs associated with the concurrent performance of circumventing approaching virtual pedestrians (VRPs) while attending to an auditory-based cognitive task and; (2) gaze behaviour associated with the VRP circumvention task in single and dual-task conditions. Methodology Twelve individuals with m/sTBI (age = 43.3 ± 9.5 yrs; >6 mo. post injury) and 12 healthy controls (CTLs) (age = 41.8 ± 8.3 yrs) were assessed while walking in a virtual subway station viewed in a head-mounted display. They performed a collision avoidance task with VRPs, as well as auditory-based cognitive tasks (pitch discrimination and auditory Stroop), both under single and dual-task conditions. Dual-task cost (DTC) for onset distance of trajectory deviation, minimum distance from the VRP, maximum lateral deviation, walking speed, gaze fixations and cognitive task accuracy were contrasted between groups using generalized estimating equations. Results In contrast to CTLs who showed locomotor DTCs only, individuals with m/sTBI displayed both locomotor and cognitive DTCs. While both groups walked slower under dual-task conditions, only individuals with m/sTBI failed to modify their onset distance of trajectory deviation and maintained smaller minimum distances and smaller maximum lateral deviation compared to single-task walking. Both groups showed shorter gaze fixations on the approaching VRP under dual-task conditions, but this reduction was less pronounced in the individuals with m/sTBI. A reduction in cognitive task accuracy under dual-task conditions was found in the m/sTBI group only. Conclusion Individuals with m/sTBI present altered locomotor and gaze behaviours, as well as altered cognitive performances, when executing a collision avoidance task involving moving pedestrians in dual-task conditions. Potential mechanisms explaining those alterations are discussed. Present findings highlight the compromised complex walking abilities in individuals with m/sTBI who otherwise present a good locomotor recovery.

“…Also, visual cues facilitate a compensatory shift to goal-directed control of movement, which is more robust to deterioration in Parkinson’s disease ( Drucker et al, 2019 ), helping to bypass the impaired basal ganglia and improving the frontal activity ( Beeler, 2011 ; Beeler et al, 2013 ). A more conscious motor control strategy reduces gait asymmetry during obstacle circumvention phase in PwPD ( Corradini et al, 2022 ). The obstacle seems to be used as a guide in the avoidance phase, such as a visual reference to refine adjustments for positioning their feet to the obstacle, and the individual’s motor behavior to a safe performance ( Corradini et al, 2022 ).…”

“…A higher asymmetry may be characterized as adaptive or maladaptive change of motor control ( Peterson and Fling, 2018 ; Berenguer-Rocha et al, 2020 ; Knights et al, 2021 ) of the neural systems ( Riederer and Sian-Hülsmann, 2012 ; Claassen et al, 2016 ). Considering that the obstacle can guide GI and improve motor and brain control ( Maidan et al, 2016 ; Corradini et al, 2022 ), we hypothesize that when an obstacle will be in place, the asymmetry of APAs and cortical activity parameters would reduce, regulating asymmetry, especially in PwPD vs. neurologically healthy people.…”

BackgroundGait asymmetry and deficits in gait initiation (GI) are among the most disabling symptoms in people with Parkinson’s disease (PwPD). Understanding if PwPD with reduced asymmetry during GI have higher asymmetry in cortical activity may provide support for an adaptive mechanism to improve GI, particularly in the presence of an obstacle.ObjectiveThis study quantified the asymmetry of anticipatory postural adjustments (APAs), stepping parameters and cortical activity during GI, and tested if the presence of an obstacle regulates asymmetry in PwPD.MethodsSixteen PwPD and 16 control group (CG) performed 20-trials in two conditions: unobstructed and obstructed GI with right and left limbs. We measured, through symmetry index, (i) motor parameters: APAs and stepping, and (ii) cortical activity: the PSD of the frontal, sensorimotor and occipital areas during APA, STEP-I (moment of heel-off of the leading foot in the GI until the heel contact of the same foot); and STEP-II (moment of the heel-off of the trailing foot in the GI until the heel contact of the same foot) phases.ResultsParkinson’s disease showed higher asymmetry in cortical activity during APA, STEP-I and STEP-II phases and step velocity (STEP-II phase) during unobstructed GI than CG. However, unexpectedly, PwPD reduced the level of asymmetry of anterior–posterior displacement (p < 0.01) and medial-lateral velocity (p < 0.05) of the APAs. Also, when an obstacle was in place, PwPD showed higher APAs asymmetry (medial-lateral velocity: p < 0.002), with reduced and increased asymmetry of the cortical activity during APA and STEP-I phases, respectively.ConclusionParkinson’s disease were not motor asymmetric during GI, indicating that higher cortical activity asymmetry can be interpreted as an adaptive behavior to reduce motor asymmetry. In addition, the presence of obstacle did not regulate motor asymmetry during GI in PwPD.
