Percepções de cuidadores familiares sobre o programa de preparo de alta hospitalar ao idoso com acidente vascular cerebral : indicativos à educação em saúde

Um programa de preparo de alta hospitalar, enquanto uma estratégia de Educação em Saúde, pode contribuir para que a família ou o idoso possam dar continuidade aos cuidados no contexto domiciliar, após a alta hospitalar. Assim, este estudo de caráter qualitativo descritivo objetiva analisar a percepção que tem o cuidador familiar de idosos com Acidente Vascular Cerebral (AVC) em relação ao Programa de preparo de alta para o paciente com seqüelas neurológicas de um Hospital Universitário. Após aprovação pelo Comitê de Ética e Pesquisa da instituição onde foi desenvolvido o presente estudo, foram entrevistados 12 cuidadores familiares de 9 idosos que participaram de tal Programa. As entrevistas foram transcritas e seu conteúdo foi analisado conforme a técnica de análise de conteúdo, emergindo quatro categorias: opinião sobre o programa, adequação das orientações às demandas de cuidados, pontos de melhoria e repercussões do ser cuidador. Assim, sugere-se a implantação de programas similares nos serviços de saúde, bem como o desenvolvimento de estratégias educativas em saúde que contemplem o idoso com AVC e sua família.

Evuloção cognitiva e funcional de pacientes pós-acidente vascular cerebral - AVC

PURPOSE: Stroke is a high-incidence cerebrovascular disease with elevated morbidity that results in impairments such as functional disabilities. This study aimed to investigate the functional evolution of individuals in the first six months post-stroke. METHOD: Longitudinal study with 42 stroke patients. The functional independence measure (FIM) and The National Institutes of Health Stroke Scale (NIHSS) were used by multidisciplinary staff 3 times in each participant; the first application was at admission to rehabilitation and the others three and six months later. RESULTS: Sample predominantly female (57%), married (52%), mean age 65.26 ±10.72 years, elementary schooling level (43%), ischemic stroke (91%), and right cerebral hemisphere (74%). Motor FIM scores and NIHSS scale showed improvement in the 3 evaluations, with significant p-value (<0.001). There was a strong relation between motor FIM evolution and NIHSS evolution (r = - 0.69 p-value< 0.001). CONCLUSIONS: It was observed that functional evolution at 6 months post-stroke was significant and the smaller the evolution of clinical impairment in these patients, the larger the evolution of their functional independence. The study is important because it allows a more appropriate therapeutic planning according with functional evolution in stroke rehabilitation

Relação entre depressão e desequilíbrio postural em idosos que sofreram acidente vascular encefálico

INTRODUCTION: The incidence of stroke it increases with the aging and each successive decade above 55 years leads to a doubling of stroke incidence. Among the current complications of stroke are the unbalance postural and depression. OBJECTIVES: To evaluate and correlate the postural balance and depression in elderly with and without stroke. MATERIALS AND METHODS: We evaluated 38 subjects (19 with stroke and 19 without). The balance was evaluated by Berg Balance Scale and the depression by Yesavage Depression Scale. RESULTS: Elderly with stroke presented depression when compared with elderly without the disease (p < 0.0001). The risk of falling in elderly with stroke was 102 times higher than in elderly without stroke. There was a correlation between depression and balance (r = -0.55; p = 0.01). CONCLUSION: Elderly patients with sequels of stroke have unbalance and greater depression, when compared with elderly of same age without the disease.

Capacidade funcional de hemiparéticos crônicos submetidos a um programa de fisioterapia em grupo

Este estudo tem como objetivos analisar a eficácia da fisioterapia em grupo sobre a marcha, o equilíbrio corporal e o risco de queda, e verificar se há correlação entre a capacidade funcional da marcha e o equilíbrio em indivíduos com hemiparesia crônica. Participaram do estudo 21 adultos hemiparéticos, com idade média de 58,9±10,6 anos, com seqüela de no mínimo 1 ano após acidente vascular encefálico isquêmico ou hemorrágico. Os sujeitos foram submetidos a um programa de 1 hora de fisioterapia em grupo duas vezes por semana durante seis meses. Foram avaliados por meio da escala de equilíbrio de Berg (EEB) e do teste de levantar e caminhar cronometrado TLCC (TUG, na sigla em inglês de timed up & go) antes do programa, após 13 e ao fim de 26 semanas. Os resultados mostram uma redução progressiva, embora não-significativa, no tempo de execução do TLCC e aumento progressivo, também não-significativo, do escore na EEB. Foi observada forte correlação entre as duas escalas (r=0,7, p<0,05). Assim, a terapia não foi efetiva para produzir melhora nos escores dos testes, mas contribuiu para manter a mobilidade.

Efeitos do treino em esteira com suporte parcial de peso e do método de facilitação neuromuscular proprioceptiva na marcha hemiparética: estudo comparativo

Objective: To compare the effects of the treadmill training with partial body-weight support (TPBWS) and Proprioceptive Neuromuscular Facilitation (PNF) method on gait of subjects with chronic stroke. Design: Quasi-experimental study. Setting: Laboratorial research. Participants: Twenty-three subjects (13 men and 10 women), with a mean age of 56,7 ± 8,0 years and a mean time since the onset of the stroke of 27,7 ± 20,3 months, and able to walk with personal assistance or assistive devices. Interventions: Two experimental groups underwent gait training based on PNF method (PNF group, n=11) or using the TPBWS - Gait Trainer System 2, Biodex, USA (TPBWS group, n=12), for three weekly sessions, during four weeks. Measures: Evaluation of motor function - using the Stroke Rehabilitation Assessment of Movement (STREAM) and the motor subscale of the Functional Independence Measure (motor FIM) -, and kinematic gait analyze with the Qualisys System (Qualisys Medical AB, Gothenburg, Sweden) were carried out before and after the interventions. Results: Increases in the STREAM scores (F=49.189, P<0.001) and in motor FIM scores (F=7.093, P=0.016), as well as improvement in symmetry ratio (F=7.729, P=0.012) were observed for both groups. Speed, stride length and double-support time showed no change after training. Differences between groups were observed only for the maximum ankle dorsiflexion over the swing phase (F=6.046, P=0.024), which showed an increase for the PNF group. Other angular parameters remain unchanged. Conclusion: Improvement in motor function and in gait symmetry was observed for both groups, suggesting similarity of interventions. The cost-effectiveness of each treatment should be considered for your choice

Reabilitação em disfagia orofaríngea neurogênica: sabor azedo e temperatura fria

TEMA: reabilitação em disfagia orofaríngea neurogênica OBJETIVO: apresentar revisão de literatura sobre os controles neurofisiológicos da deglutição orofaríngea e a influência do sabor azedo e da temperatura fria no mecanismo da deglutição. CONCLUSÃO: quanto à questão do controle central da deglutição, ainda existem controvérsias em relação ao sabor azedo e a temperatura fria. Esses dois parâmetros provocam mudanças na dinâmica da deglutição, podendo trazer benefícios aos indivíduos acometidos por disfagia orofaríngea neurogênica. Porém, tais achados sugerem a necessidade de investigações futuras com populações randomizadas.

Sour taste and cold temperature in the oral phase of swallowing in patients after stroke

PURPOSE: To determine the effect of sour flavor and cold temperature on oral transit time during swallowing. METHODS: Participants were 52 subjects (28 male and 24 female) with ages between 50 and 80 years (median=66 years), after ischemic stroke involving right or left side damage and mild to moderate oropharyngeal dysphagia. Videofluoroscopy was performed to analyze the swallowing times. Each subject was assessed during swallowing of a paste consistency bolus offered in 5 ml spoons, with a total of four different stimuli (natural, cold, sour and sour-cold). After the exam, the oral transit time was measured using specific software. The oral transit time (starting at the beginning of the bolus movement in the mouth) and the total oral transit time (starting at the moment that the bolus is placed in the mouth) were measured. RESULTS: The association between sour and cold stimuli caused a significant decrease of oral transit time and total oral transit time. CONCLUSION: Sour flavor and cold temperature reduced oral transit time in stroke patients.

Desempenho motor de pacientes com acidente vascular cerebral em um jogo baseado em realidade virtual

The Cerebral Vascular Accident (CVA) is the leading cause of motor disability in adults and elderly and that is why it still needs effective interventions that contribute to motor recovery. Objective: This study was aimed to evaluate the performance of stroke patients in chronic stage using a virtual reality game. Method: 20 patients (10 with injury to the left and 10 to the right side), right-handed, average age 50.6 ± 9.2 years, and 20 healthy subjects with average age of 50.9 ± 8.8, also right-handed participated. The patients had a motor (Fugl-Meyer) and muscle tone assessment (Ashworth). All participants made a kinematic evaluation of the drinking water activity and then underwent training with the table tennis game on XBOX 360 Kinect®, 2 sets of 10 attempts for 45 seconds, 15 minutes rest between sets, giving a total of 30 minutes session. After training the subjects underwent another kinematic evaluation. The patients trained with the right and left hemiparect upper limb and the healthy ones with the right and left upper limb. Data were analyzed by ANOVA, t Student test and Pearson correlation. Results: There was significant difference in the number of hits between the patients and healthy groups, in which patients had a lower performance in all the attempts (p = 0.008), this performance was related to a higher level of spasticity (r = - 0.44, p = 0.04) and greater motor impairment (r = 0.59, p = 0.001). After training, patients with left hemiparesis had improved shoulder and elbow angles during the activity of drinking water, approaching the pattern of motion of the left arm of healthy subjects (p < 0.05), especially when returning the glass to the table, and patients with right hemiparesis did not obtain improved pattern of movement (p > 0.05). Conclusion: The stroke patients improved their performance over the game attempts, however, only patients with left hemiparesis were able to increase the angle of the shoulder and elbow during the functional activity execution, better responding to virtual reality game, which should be taken into consideration in motor rehabilitation

Controle circadiano e homeostático do sono-virgília em pacientes com acidente vascular encefálico e correlações com a qualidade de vida e o nível de atividade física

The cerebral vascular accident is a neurological dysfunction of vascular origin that leds to development of motor sensibility, cognitive, perceptive and language deficits. Despite the fact that the main sleep disorders in stroke patients are well known, it is still necessary to analyze which mechanisms of regulation of sleep and wakefulness are affected. The objective of this study was to evaluate the changes in the circadian and homeostatic control of sleep-wakefulness in stroke patients and the correlations with quality of life and level of physical activity. The study analyzed 22 stroke patients (55± 12 years old) and 24 healthy subjects (57 ±11 years old). The instruments used in this study were questionnaires on sleep quality, daytime sleepiness, quality of life, physical activity level and the actigraphy. The data were analyzed using the Student `t test, Mann-Whitney test, ANOVA and Spearman's correlation tests. The results showed stability in the sleep-wake circadian expression with changes in the amplitude of the rhythm. However, significant changes were found related to the homeostatic component characterized by increased sleep duration, increased latency, fragmented sleep and lower sleep efficiency. Additional data showed decreased quality of sleep and increased daytime sleepiness, as well as decreased quality of life and level of physical activity. The results indicate that the interaction of circadian and homeostatic control of sleep-wake is compromised and the main reason might be because of the homeostatic component and the lower activity level resulting from the brain damage. Thus, further studies may be developed to evaluate whether behavioral interventions such as increased daytime activity and restriction of sleep during the day can influence the homeostatic process and its relation to circadian component, resulting in improved quality of nocturnal sleep in stroke patients

Negligência unilateral pós-acidente vascular encefálico: atuação da Terapia Ocupacional

Unilateral Neglect Syndrome is one of the consequences of cerebral vascular accident (CVA) generally following right parietal lobe lesion, leading to the impairment of perceptive visual, spatial and attention functions. The patient affected does not realize the environmental stimuli on the contralesional hemibody. Occupational therapy plays an important role in caring for this patient, seeking the recovery of perception, attention and social engagement. This study aimed to describe and evaluate the results of occupational therapy intervention and treatment in a single Unilateral Neglect Syndrome post CVA patient. Data were obtained from a survey of the patient’s medical records and interviews of his therapist and caretaker. The analysis of the patient’s medical records and his therapist’s report showed that the patient responded satisfactorily to treatment, presenting a decrease of the left unilateral neglect at the end of the study period. The favorable outcome of the patient outlined the relevance of evaluating the effects of Occupational Therapy interventions for clinical unilateral neglect syndrome.

Influência dos factores de risco vascular no desempenho cognitivo

O objetivo deste estudo consiste em verificar até que ponto os sujeitos com fatores de risco vascular acentuados apresentam alterações no seu desempenho cognitivo, na ausência de lesão vascular conhecida. Para tal, os défices apresentados por estes foram comparados com sujeitos que se encontram na fase pós-aguda do AVC (Acidente Vascular Cerebral) e sujeitos do grupo de controlo. Os défices cognitivos foram avaliados através de uma bateria de testes neuro psicológicos estandardizados, nos quais se avaliou a atenção, memória e funções executivas. Os resultados parecem confirmar a existência de um défice significativo nos sujeitos com fatores de risco em relação ao grupo de controlo, no que diz respeito à memória verbal e visual a curto-prazo e capacidade de aprendizagem. Assim, com base nos resultados podemos inferir a possibilidade de que os fatores de risco, por si só, podem causar determinado tipo de défice cognitivo. / ABSTRACT: The aim of this study is to determine the extent to which individuals with vascular risk factors have pronounced changes in their cognitive performance, in the absence of known vascular injury. For this purpose, the deficits presented by these subjects were compared to those who are in the post-acute stage of the Stroke and subjects in the control group. Cognitive deficits were assessed using a battery of standardized neuro¬ psychological tests, in which it was assessed attention, memory and executive functions. The results seem to confirm the existence of a significant deficit in subjects with risk factors in relation to the control group in what regards to short-term verbal and visual memory and learning ability. Therefore, based on the results we may imply the possibility that risk factors by themselves can cause certain types of cognitive impairment.

Cerebral perfusion CT: Current state of the art : P44

Purpose: The aim of this educational poster is to introduce the technical principles of cerebral perfusion CT and to provide examples of its clinical applications and potential limitations in the everyday emergency practice. Methods and materials: Cerebral perfusion CT is a well established investigatory tool for many vascular and parenchymal brain dysfunctions. CT perfusion maps allow a semiquantitative assessment of cerebral perfusion. Results: Currently, cerebral perfusion CT has a pivotal role in differentiating reversible from irreversible ischemic parenchymal insult besides its integral role in grading vasospasm after subarachnoid hemorrhage. Furthermore, cerebral perfusion CT can be coupled to acetazolamide administration in order to assess the cerebrovascular reserve capacity before performing extra-/intra-cranial bypass surgery in patients with cerebral vascular insufficiency. Cerebral perfusion CT can also identify diffuse abnormalities of cerebral perfusion in children with traumatic brain injury showing a low initial GCS in order to predict the final outcome regarding the late occurrence of irreversible parenchymal damage. Cerebral Perfusion CT is also able to detect focal parenchymal perfusion abnormalities in acute epileptic seizures. Conclusion: Cerebral perfusion CT can be integrated in the management of many vascular, traumatic and functional disorders of the brain.
