Stroke, or cerebrovascular accident (CVA), is a prominent cause of long term disability in the United States. It has been evidenced that the outcome of a CVA patient differs as a function of the cerebral hemisphere that is damaged by the stroke, especially in terms of emotional changes. The Right Hemisphere Model of Emotion posits that the right hemisphere is specialized for processing emotional content, regardless of valence. In contrast, the Bi-Hemispheric Model of Emotion posits that each hemisphere has its own emotional specialization. The current experiment tested the competing predictions of the two theoretical perspectives in a mixed sample of left cerebrovascular accident (LCVA) patients and right cerebrovascular accident (RCVA) patients using a Dichotic Listening task and the Affective Auditory Verbal Learning Test (AAVLT). Heart Rate (HR) and Pulse Oxygen Saturation (SpO2) were also recorded as sympathetic measures. It was expected that the predictions of the Bi-Hemispheric Model would be supported. A series of mixed design ANOVAs were used to analyze the data. Results revealed that both groups may have exhibited decreased auditory detection abilities in the ear contralateral to CVA location. Additionally, CVA patients recalled significantly more positive words, than negative or neutral words, and exhibited a significant learning curve. LCVA patients exhibited a recency effect, while RCVA patients exhibited a heightened primacy effect. Findings from HR and SPO2 measures suggested a parasympathetic response to neutral information as well as an impaired sympathetic response to negative information in RCVA patients. Taken together these results lend partial support to the hypotheses drawn from the Bi-Hemispheric Model of Emotion, as evidenced by the diametrically opposite effects in these groups, which appears to reflect opposing cerebral processes. / Ph.

Background. Carotid stenosis is an important cause of stroke. Carotid endarterectomy is a means of reducing the burden of stroke but is of marginal benefit in individuals with asymptomatic carotid stenosis. The identification of factors associated with increased risk of cerebral ischemic events would help select individuals who may obtain a greater benefit. / Methods. A comprehensive search was performed to identify studies examining risk factors for cerebral ischemic events in patients with asymptomatic carotid stenosis. Inclusion criteria were defined a priori. Relevant studies were reviewed, assessed for quality, and data were extracted. / Results. Thirty-four studies met the inclusion criteria. There was a suggestion of increasing neurological events with increasing severity and progression of carotid stenosis. There was some evidence for an association with carotid plaque morphology. No consistent association was found with clinical factors, impaired cerebral vasoreactivity, or cerebral embolic signals. / Conclusions. The evidence is insufficient to reliably identify individuals with asymptomatic carotid stenosis who are at a higher risk of cerebral ischemic events.

Title: The effect of regular training in Locomat system changing the stereotype of gait of patients after the cerebrovascular accident Objectives: The purpose of this thesis is to evaluate whether it is appropriate to use the Locomat system in therapy of gait of patients after the cerebrovascular accident, what is the effect of regular training of these patients in the Locomat system on their stereotype of gait and whether the training in the Locomat system of patients after the cerebrovascular accident is more effective in comparison with other physiotherapeutic practices. Methods: The thesis was processed in the Kladruby Rehabilitation Centre on 14 probands, who were divided after the entrance examination in order to form two equivalent homogenous groups. The first group of seven members was experimental, the second one was control. At the beginning of the study the rate of gait disorder was specified at each proband using standardized method of Wisconsin Gait Scale, they also underwent 10 - Meter Walk Test and 6 - Minute Walk Test. Afterwards all the probands absolved a three-week lasting standard regime of rehabilitation. The probands of research groups absolved except the rehabilitation regime during this time period regularly 5x times a week fifteen 30-minute lasting therapy units in the...

Ainda não há consenso entre os diversos estudiosos do tema sobre as variáveis cinemáticas das articulações durante a marcha hemiparética e uma das articulações mais discutidas é o joelho: como as principais alterações se comportam ao longo do ciclo de marcha e se a velocidade da marcha modifica os padrões de mobilidade das articulações. O objetivo deste estudo foi avaliar as variáveis encontradas na cinemática angular da articulação do joelho e descrever as alterações encontradas na marcha hemiparética oriunda de acidente vascular cerebral. Participaram deste estudo 66 pacientes adultos de ambos os sexos com diagnóstico de seqüela de acidente vascular cerebral isquêmico com hemiparesia direita ou esquerda. Todos os participantes foram submetidos a avaliação tridimensional da marcha com o sistema Vicon 370 e os valores da cinemática angular da articulação do joelho foram selecionados para análise. Os resultados foram distribuídos em quatro grupos formados de acordo com a mediana da velocidade de marcha e lado do acometimento. As características clínicas relevantes encontradas e que devem ser levadas em consideração no momento da escolha da melhor conduta de tratamento demonstram no apoio alteração importante no mecanismo de resposta a carga e hiperextensão do joelho no apoio simples. Na fase de balanço redução do pico de flexão e amplitude de movimento do joelho. Há semelhança na cinemática angular da articulação do joelho durante a marcha hemiparética oriunda de acidente vascular cerebral, mas, não foi encontrado um padrão definido para esta articulação na população avaliada / There is still no consensus among the different specialists on this subject on the kinematics variation during the hemiparetic gait, and one of the most frequently discussed joints is the knee: the way the main changes take place during the gait cycle, and whether the gait velocity changes the patterns of joint mobility. This study aims at evaluating the variables found in the angular kinematics of the knee articulation and at describing the alteration found in the hemiparetic gait resulting from cerebrovascular accident. This study comprised 66 adult patients, both gender with diagnosis of a sequel resulting from ischemical cerebrovascular accident with both right and left hemiparesis. All the participants were submitted to three-dimensional gait evaluation with Vicon 370 and the values of the angular kinematics of the joint knee were selected for analysis. The results were distributed in four groups formed in agreement with the medium of the gait speed and side taken. The clinical relevant characteristics found and that should be taken into account when choosing the best treatment demonstrate, in the stance, an important mechanism of loading response and, in the simple stance, knee hyperextension. In the swing phase, reduction of the peak flexion and movement amplitude of the knee. We believe that our findings presented here may aid the conduct when facing these patients in the sense of preventing the occurrence of problems found, and also in the attempt of finding the origin of these problems
