“…The increase in double support duration was a compensatory strategy to maintain walking stability. Hamilton et al 20 showed greater decrements in performance under dual-task conditions in cognitive task performance, walking speed and swing-time variability in MS patients. Kalron et al 19 also showed that combined walking and cognitive tasks were expressed in prolonged double support duration, as shown by the present results.…”

ARTICLE 521Walking execution is not affected by divided attention in patients with multiple sclerosis with no disability, but there is a motor planning impairment A execução da marcha não é afetada pela atenção dividida em pacientes com esclerose múltipla sem incapacidade, mas existe um comprometimento do planejamento motor ABSTRACT Purpose: We analysed the cognitive influence on walking in multiple sclerosis (MS) patients, in the absence of clinical disability. Method: A case-control study was conducted with 12 MS patients with no disability and 12 matched healthy controls. Subjects were referred for completion a timed walk test of 10 m and a 3D-kinematic analysis. Participants were instructed to walk at a comfortable speed in a dual-task (arithmetic task) condition, and motor planning was measured by mental chronometry. Results: Scores of walking speed and cadence showed no statistically significant differences between the groups in the three conditions. The dual-task condition showed an increase in the double support duration in both groups. Motor imagery analysis showed statistically significant differences between real and imagined walking in patients. Conclusion: MS patients with no disability did not show any influence of divided attention on walking execution. However, motor planning was overestimated as compared with real walking.Key words: mild cognitive impairment, multiple sclerosis, walking. RESUMOO objetivo do estudo foi analisar a influência cognitiva na caminhada de pacientes com esclerose múltipla (EM) sem incapacidade clínica. Foi conduzido um estudo caso-controle com 12 pacientes com EM sem incapacidade com 12 pessoas saudáveis como controles pareados. Os sujeitos fizeram um teste de caminhada de 10 metros , acompanhado de análise cinemática 3D, e foram orientados a caminhar em velocidade confortável, realizando dupla-tarefa (tarefa aritmética), e o planejamento motor foi medido pela cronometria mental. Os valores de velocidade da caminhada e da cadência não evidenciaram diferenças estatisticamente significativas entre os grupos nas três condições. A condição de dupla-tarefa demonstrou um aumento na duração do duplo apoio em ambos os grupos. A imagética motora evidenciou diferenças estatisticamente significativas entre a caminhada real e a imaginada nos pacientes com EM. Pacientes com EM sem incapacidade não apresentaram influência da atenção dividida na execução da caminhada. Entretanto, o planejamento motor esteve superestimado.Palavras-Chave: comprometimento cognitivo leve, esclerose múltipla, caminhada.

“…Driving impairments might be expected in various populations, as normal aging, clinical neurologic disease (namely, Alzheimer's Disease, Parkinson's Disease, Multiple Sclerosis, Stroke) and psychiatric conditions (namely, Major Depression, Schizophrenia) that affect a person's cognitive functioning and may impact driving ability (Marcotte and Scott, 2009). ACE-R research has examined these conditions (e.g., Alexopoulos et al, 2010;Dudas et al, 2005;Hamilton et al, 2009;Kwak et al, 2010;Mathew et al, 2011;Pendlebury et al, 2012;Reyes et al, 2009).…”

a b s t r a c tConsiderable research has shown that neuropsychological tests are predictive of real-world driving ability. The Mini-Mental State Examination (MMSE) is a brief cognitive test that has been commonly used in the assessment of older drivers. However, this test has inherent problems that limit its validity to evaluate cognitive abilities related to driving and to screen for driving impairments in non-demented people. Therefore, it is useful to test new screening instruments that may predict potential unsafe drivers who require an in-depth neuropsychological assessment in a specialised centre. To date, the utility of the Addenbrooke's Cognitive Examination Revised (ACE-R) as an indicator of driving ability has not been established. In the current study, fifty older drivers (mean age = 73.1 years) who were referred for a psychological assessment, the protocol of which included the ACE-R, underwent an on-road driving test. Using linear discriminant analyses, the results highlighted the higher classification accuracy of the ACE-R compared to the MMSE score, particularly for detecting unsafe drivers. Measures of visuospatial and executive functions, which are not incorporated in the MMSE score, had an incremental value in the prediction of driving ability. This emerging brief cognitive test may warrant additional study for use in the fitness to drive assessment of older adults.
