ABSTRACT
Objective:To explore the effect of cognitive-motor dual task training on vascular mild cognitive impairment (VaMCI) in old patients. Methods:From March to September, 2019, 76 old patients with VaMCI in three general hospitals were divided into control group (n = 38) and intervention group (n = 38). All the patients accepted health education, while the intervention group accepted cognitive-motor dual task training in addition, for three months. They were assessed with Montreal Cognitive Assessment-Beijing Version (MoCA-BJ) and Trail Making Test (TMT-A) before and after intervention, and the one-year incidence of fall before and after intervention was investigated in the intervention group. Results:Two cases in the control group and three cases in the intervention group dropped down. The total score and dimension scores of MoCA-BJ were more significantly in the intervention group than in the control group after intervention (|Z| > 2.002, P < 0.05), except the dimension of naming, while the time for TMT-A was significantly less (Z = -5.949, P < 0.001). The one-year incidence of fall decreased significantly during the year after intervention (χ2 = 10.080, P < 0.01). Conclusion:Cognitive-motor dual task training can improve the cognitive function of older VaMCI patients, especially for attention and executive function, and reduce the risk of fall.
ABSTRACT
Resumo Objetivo Investigar a influência da escolaridade nos ganhos de função executiva após o treinamento com dupla tarefa (DT). Método Estudo exploratório realizado com 31 idosas, com escolaridade ≥3 anos e sem alterações das funções cognitivas rastreadas pelo Miniexame do Estado Mental (MEEM). As participantes foram distribuídas em dois grupos a partir do critério escolaridade, sendo o Grupo 1 com escolaridade de três a sete anos (n=17) e o Grupo 2 com escolaridade igual e superior a oito anos (n=14). Foram avaliadas as funções executivas antes e após o treinamento através dos testes Stroop, Exame Cognitivo de Addenbrooke - Revisado (ACE-R) e Trilhas B. O protocolo de intervenção consistiu em três sessões semanais, duração de 50 minutos cada, com a realização de atividades de DT cognitiva e motora, associadas à caminhada, por 12 semanas. Resultados A ANOVA indicou que o treinamento de DT melhorou significativamente o desempenho nos testes Stroop (F=5,95; p=0,02) e ACE-R (F=18,33; p<0,0001), independentemente da escolaridade. Foi verificado efeito do grupo nos testes ACE-R (F=14,65; p<0,001) e Trilhas B (F=18,74; p<0,001). Em nenhum dos testes analisados, foi observado efeito da interação grupo x tempo (0,04<F<2,14; 0,15<p<0,95). Conclusão O treinamento de DT pode melhorar significativamente a função executiva de idosas, independente do nível de escolaridade, podendo ser utilizado na prática clínica como uma proposta de intervenção, visando o ganho de função executiva.
Abstract Objective Investigate the influence of education levels on gains in executive function after dual-task (DT) training. Method Exploratory study carried-out with 31 old women, who had ≥3 years of education and without cognitive deficits, as screened by the Mini-Mental State (MMS). The participants were distributed in two groups: group 1: 3 to 7 years of education (n=17) and group 2: ≥8 years of education (n=14). Measures of executive function (Stroop, Addenbrooke's Cognitive Examination - Revised (ACE-R), and Trail Making Test - B (B-Trails)) were obtained before and after training. The intervention protocol consisted of three weekly sessions of 50 minutes each and included cognitive and motor DT training, associated with walking, over 12 weeks. Results ANOVA indicates that DT training improved the performance of Stroop (F=5.95; p=0.02) and ACE-R (F=18.33; p<0.0001) tests, regardless of the education level. The effect of the ACE-R test group (F=14.65; p<0.001) and B-Trails (F=18.74; p<0.001) was verified. In none of the investigated tests, the interaction effects between groups and time (0.04<F<2.14; 0.15<p<0.95) was observed. Conclusion DT training has the potential to generate effects and can positively improve the executive function of older women, regardless of educational level and may be used within clinical practice, aiming at improving executive function.
ABSTRACT
Multiple tasks performance is necessary for daily living to adapt environments. The stroke patients often fall in ability of dual tasks, which may be less improved by routine rehabilitation. This paper summarized the researches about the effect of dual-task training on the balance function of stroke patients, and discussed the possible ways to it.
ABSTRACT
@#Objective To observe the effects of dual-task motor training on motor and balance function for stroke patients. Methods From January, 2016 to June, 2017, 30 patients with stroke were assigned randomly into control group (n = 15) and treatment group (n = 15). Both groups accepted routine physical therapy, the control group accepted anti-gravity treadmill training, while the treatment group accepted dual-task training with anti-gravity treadmill, for four weeks. They were measured with balance training and evaluation system, and assessed with Fugl-Meyer Assessment-lower extremity (FMA-L), Berg Balance Scale (BBS) and modified Barthel Index (MBI), before and after treatment. Results The range of swaying on X axial (Rx) and Y axial (Ry), as well as rectangle area (RecArea) decreased after treatment in the treatment group (t > 4.719, P < 0.001), while RecArea decreased in the control group (t = 5.069, P < 0.001). Ry and RecArea were less in the treatment group than in the control group (t > 2.288, P < 0.05). The scores of FMA-L, BBS and MBI improved after treatment in both groups (t > 7.316, P < 0.001), and improved more in the treatment group than in the control group (t > 2.322, P < 0.05). Conclusion The dual-task training via anti-gravity treadmill may improve motor and balance function in stroke patients, and promote the activities of daily living.
ABSTRACT
OBJECTIVE: To investigate the effect of dual-task training on the recovery of balance ability and cognitive function in patients with subacute stroke. METHODS: Twenty patients (12 males and eight females; average age, 59.70 years) with subacute stroke were enrolled in this study. All participants were randomly assigned to one of two groups, the dual-task group (n=10) or the control group (n=10). The dual task was simultaneous balance and cognitive training using the BioRescue. All patients were evaluated with posturographic parameters and the Berg Balance Scale for balance ability, a computerized neuropsychological test and the Korean version of the Mini-Mental State Examination for cognitive function, the Fugl-Meyer Assessment for motor function, and the Korean-Modified Barthel Index for activities of daily living (ADL) function before and after 4 weeks of rehabilitation. RESULTS: The dual-task group showed significant improvements in the pressure of the weight distribution index (WDI), surface area, and length of the stability index during the eyes-open condition; surface area of the limit of stability (LOS) on the hemiparetic and intact sides, and the auditory continuous performance test and backward visual span test after rehabilitation. Although no significant difference was observed for the changes in balance ability or cognitive, motor, and ADL functions between the groups, changes in the WDI pressure during the eyes-open condition and in the area ratio of LOS (hemiparetic/intact) showed a tendency to improve in the dual-task group. CONCLUSION: Our findings suggest that dual-task training could be as effective as conventional balance training for improving balance and cognition in subacute post-stroke patients.
