“…Bowen et al 17) noted that stroke patients' gait velocity increased but their ability to balance decreased while walking under dual-task conditions. Bensoussan et al 4) reported that stroke patients' postural adjustment cability declined when they performed dual tasks, and Cockburn et al 18) noted that stroke patients' gait velocity and performance of dual tasks decreased while walking under dual-task conditions. This study selected single-and dual-task balance exercises as methods to evaluate the training of stroke patients' ability to balance.…”

“…In particular, in stroke patients, right-left imbalance causes asymmetric posture and reduces individual's ability to control center of gravity. This triggers serious problems in the body's ability to balance and to regulate posture resulting in gait disturbances 4) . This inability to properly balance primarily restricts stroke victims' daily activities and increases their risk of falling, thereby posing a serious threat to their health 5) .…”

Abstract.[Purpose] The purpose of this study was to evaluate the effects of dual-task balance training on stroke patients' balance performance. [Subjects and Method] Forty stroke patients were allocated equally and randomly to an experimental group and a control group. The experimental group performed the dual-task balance training of standing on a balance pad and moving a cup containing water. The control group performed the single-task balance training of maintaining balance on a balance pad. All the subjects exercised five times per week for 4 weeks. Each group's balance performance (sway area, sway path, and maximum velocity) was measured using a balance performance monitor, both prior to and after the exercise program.[Results] Comparing measurements from before and after the exercise program, both the experimental group and the control group showed statistically significant changes in sway area and maximum velocity, but not for sway path. Comparing the two groups, the experimental group showed more significant changes than the control group in sway area and maximum velocity, but there were no significant differences in sway distance between the two groups.[Conclusion] For the stroke patients, Dual-task balance training was more effective than single-task balance training. The results should help to promote the wider clinical application of dual-task balance training programs for stroke patients.

“…28 Executive dysfunctions are widely documented in the neurological population. 29,30 In studies conducted with individuals diagnosed with Alzheimer's disease, it was observed that their dual tasking performance was already compromised since the early stages of the disease. This indicates that even when the cognitive deficit is not evident, the problems walk while performing subtractions, configuring it as a motor-cognitive dual task.…”

“…5,11,12 The interference can also occur in the form of a worse performance of the upper limb, a decrease in the number of words spoken, and an increase in body oscillation, among other things. [13][14][15] Three theoretical models were developed in order to explain the dual task interference. The capacity theory -or theory of sharing resources (the capacity model), is based on the assumption that the attention resources are limited, leading to loss in the execution of one or two tasks when the processing capacity is exceeded.…”

Objective: Discuss the possibilities of dual task in the ambit of neurological rehabilitation. Methods: A survey was conducted in PUBMED, MEDLINE, LILACS, and PEDro, using the keywords "dual task" associated with each of the following terms separately: treatment, physical therapy, rehabilitation, exercise, training, divided attention, executive functions, and attentional demands. We selected only clinical trials that used dual task training in adults with neurological disease. Results: From the 2,024 articles found, 1,017 were excluded because they are duplicate. Among the remaining 1,007 articles, 998 were excluded after reviewing the abstracts. Nine articles were selected that included patients with stroke, brain injuries, Alzheimer's, and Parkinson's disease. Most articles used gait as the primary task, and in six studies the second task was cognitive. The training programs ranged between a total of 9 and 48 hours of training. Conclusion: Dual task training appears to improve gait, cognition, automation skills, and transference of learning, suggesting that this may be a valuable strategy for neurological rehabilitation. Nevertheless, it is still necessary to explain which tasks are more efficient and how long the learning retention lasts.

“…The interaction is evaluated by simultaneously conducting cognitive tasks such as calculation or memory tasks during postural control tasks such as standing or walking 8) . Hindman et al 5) reported that stroke patients experienced greater postural difficulties (e.g., sitting, standing, or walking) and were less capable of performing cognitive tasks than healthy subjects.…”

Abstract.[Purpose] The purpose of this study was to investigate the effects of dual-task performance on postural sway of patients with stroke who had previously experienced falls.[Subjects] Fifty-six patients with stroke who were receiving physical therapy were recruited on a voluntary basis from a rehabilitation unit. They were allocated to 2 groups according to their experience of falls: stroke with falls (n=26) during past 1 year and stroke without falls (n=30).[Methods] This study had a cross-sectional design. We measured the anteroposterior and mediolateral postural sway velocity during a single-task condition (postural control) and a dual-task condition (backward counting with postural control) using a force plate.[Results] The anteroposterior and mediolateral postural sway velocities under single-and dual-task conditions were significantly higher in the stroke with falls group. Furthermore, the anteroposterior and mediolateral postural sway velocity significantly increased under the dual-task condition in both the groups.[Conclusion] Experience of falls was found to increase the postural sway velocity of stroke patients. These results may be useful in balance training for the prevention of falls by stroke patients.
