“…e findings suggested that cognition is not sufficiently valued in balance function and motor rehabilitation. Recently, mounting evidence has indicated that cognitive function is involved in complex motor and posture control and that posture control during walking receives instructions from the cognitive regions of the brain [27]. e basal ganglia are a common stroke site and an important part of the execution-motor functional brain network [28].…”

Objective. The purpose of the study was to observe the effects of executive dysfunction (ED) on gait and postural control during walking after stroke. Methods. In this study, 34 subjects with stroke and ED (8 women and 26 men; age, 55.41 ± 7.89 years; time since stroke onset, 1.3 ± 0.12 months) were recruited. Stroop color-word test (SCWT), 10-meter walk test (10MWT), timed-up-and-go test (TUGT), and gait analysis were evaluated. The correlation among the correct number of Stroop tasks (SCWT-C), the number of time-consuming tasks (SCWT-T), the amount of interference (SIE-M and SIE-T) and posture control, and gait-related parameters was analyzed. Results. The results indicated that SCWT-C was negatively correlated with 10MWT, TUGT, and bilateral symmetry ( P < 0.05). However, there was no significant correlation between SCWT-C and stride ( P > 0.05). A significant negative correlation was seen between SCWT-C and bilateral symmetry ( P < 0.05). There was no significant correlation between SCWT-T and stride ( P > 0.05). SCWT-T was positively correlated with TUGT, 10MWT, and bilateral symmetry ( P < 0.05). SIE-T was positively correlated with TUGT and bilateral symmetry ( P < 0.05). There was no significant correlation between SIE-T and 10MWT or stride ( P > 0.05). SIE-M was positively correlated with TUGT and bilateral symmetry ( P < 0.05). There was no significant correlation between SIE-T and 10MWT or stride ( P > 0.05). Conclusions. ED is closely related to the decline in postural control and the occurrence of falls. In the early phases of stroke rehabilitation, physiotherapists should focus on the patients’ executive function to accelerate the recovery of postural control.

“…The correlation between turning mobility and global cognition has been observed among patients with stroke in the current study, which was line with previous studies ( 13 , 30 , 31 ). Studies have indicated a negative effect of dual-tasking on turning performance ( 10 , 11 ), and the detrimental effect was amplified in patients with poorer cognition ( 16 , 17 ), which may be due to limited cognitive capacity ( 32 ). When a task is challenging, it imposes additional cognitive demands.…”

“…Impairments were found most frequently in memory, visuospatial and executive functions, which could be an important contributor to turning dysfunction in patients with stroke ( 15 ). Stroke patients with mild cognitive impairment have been reported to have a longer time to turn around in the timed up and go (TUG) test than did stroke patients with intact cognitive abilities ( 16 , 17 ). Stroke combined with cognitive decline may have a greater influence on turning performance than stroke itself ( 16 , 17 ).…”

Turning difficulties are common in patients with stroke. The detrimental effects of dual tasks on turning indicate a correlation between turning and cognition. Cognitive impairment is prevalent after stroke, and stroke patients with mild cognitive impairment had a poorer turning performance than did stroke patients with intact cognitive abilities. Therefore, we investigated the association between turning mobility and cognitive function in patients with chronic poststroke. Ninety patients with chronic stroke (>6 months post-stroke) were recruited. Angular velocity was assessed using wearable sensors during 180° walking turns and 360° turning on the spot from both sides. Global cognition and distinct cognitive domains were assessed using the Mini-Mental State Examination. In patients with stroke, turning mobility was significantly associated with global cognitive function and distinct cognitive domains, such as visuospatial ability and language. The balance function and lower limbs strength were mediators of the association between cognition and turning. The association highlights the complexity of the turning movement and dynamic motor and cognitive coordination necessary to safely complete a turn. However, our findings should be regarded as preliminary, and a thorough neuropsychological assessment to provide a valid description of distinct cognitive domains is required.

“…This would result in increased demand on processing in the parietal cortex and the prefrontal cortex because of the interference between the motor and cognitive demands, i.e., DTI. Yu et. al., 2021) As observed in the known-group validity outcomes of the present study, the CP children had reduced balance and cognitive performance during the DT condition as compared to the TD children.…”

Introduction: Cerebral Palsy (CP) is one of the leading causes of disability globally. Children with CP often develop imbalance and gait abnormality resulting in mobility limitations. Early intervention with intensive, repetitive, task-oriented practice is the key to functional independence. However, often these intensive programs lack motivation and engagement that results in low adherence and discontinuation of physiotherapy. To address this gap, an innovative, computerized game-aided rehabilitation (CGR) platform is designed for dual-task balance training. This platform provides an integrated approach to assess and treat the balance and executive cognitive functions in young children with CP. Methodology: For the known-group validity, 50 participants (25 TD and 25 CP affected children) were recruited. Comparisons were made between the two groups for DTI and task performances to evaluate the group differences. For the pilot intervention study, 16 children with CP were recruited who were randomized into two groups viz. Conventional balance training group (CBG) and Experimental group (XG). Both group received their respective therapy thrice a week for 12 weeks. The primary outcome measures were (Peabody Developmental Motor Scale-2, Gross Motor Function Classification-88, and Pediatric Balance Scale) and CGR assessment measures [COP Analysis, Visuo-Motor (VM) tracking, and Cognitive Game (CG)].Semi-structured interview were conducted for XG participant's parents to explore their views regarding the use of CGR.iii Results: The TD group was engaged in DT whereas the CP group was struggling with balance control. For the intervention study, participants in the XG demonstrated greater improvements in all clinical and CGR outcome measures whereas the CBG demonstrated a decline in VM tracking a CG performance post-intervention. The XG parents conveyed their children's problems, their expectations, their challenges, and the positive effects of CGR balance training. Conclusion:The CGR assessment was able to differentiate between the TD and CP children's DT functional performance. The CGR balance training was found to be feasible and engaging for balance training in children with CP. The substantial improvement of balance and gross motor functions in the XG more than the CBG illustrates the effectiveness of the CGR balance training and provides baseline evidence for commencing a full-scale RCT.
