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.

Association between atherosclerotic aortic plaques and left ventricular hypertrophy in patients with cerebrovascular events

Background and Purpose - the purpose of this research was to evaluate whether an association exists between the presence of atherosclerotic plaque in the thoracic aorta and left ventricular hypertrophy (LVH) in patients with a cerebrovascular event.Methods - We included 116 consecutive patients ( 79 men; mean age, 62 +/- 12.4 years) with previous history of stroke or transient ischemic attack in a cross-sectional study. Transthoracic echocardiogram was performed to diagnose LVH and transesophageal echocardiogram for the detection of atheromas of the thoracic aorta. Continuous variables were analyzed by Student t or Mann-Whitney tests and categorized variables by Goodman test. From the significant association of LVH and age with atheromatous disease of the aorta, an adjustment to the multivariate logistic model was made using high blood pressure history or age as covariates. All of the statistical tests were carried out at a level of 5% significance.Results - Almost half of the patients (43.1%) presented atherosclerotic lesions in the aorta. LVH was present in 90.0% of patients with plaque and in only 30.3% of patients without plaque. Using high blood pressure as a covariate, the risk of patients with LVH presenting atherosclerotic plaque in the aorta was 18.23-fold greater than the risk for patients without LVH (95% CI, 5.68 to 58.54; P < 0.0001). Adding age into the model, the risk increased to 26.36 ( 95% CI, 7.14 to 97.30; P < 0.0001).Conclusions - LVH detected by conventional echocardiogram is associated with high risk of atherosclerotic plaque in the aorta and would be used as a criterion for indication of transesophageal echocardiography in patients with previous stroke or transient ischemic attack LVH.

Stroke in ancient times - a reinterpretation of Psalms 137 : 5,6

Stroke was probably first described in Psalms 136: 5-6 of the Catholic Bible, and Psalms 137:5-6 of the Evangelical Bible. Based on the Portuguese, Spanish, English, German, Dutch, Russian, Greek, and original Hebrew Bible, the significance of this Psalm is the invocation of a punishment, of which the final result would be a stroke of the left middle cerebral artery, causing motor aphasia and right hemiparesis.

Gait training with partial body weight support during overground walking for individuals with chronic stroke: a pilot study

Background: It is not yet established if the use of body weight support (BWS) systems for gait training is effective per se or if it is the combination of BWS and treadmill that improves the locomotion of individuals with gait impairment. This study investigated the effects of gait training on ground level with partial BWS in individuals with stroke during overground walking with no BWS.Methods: Twelve individuals with chronic stroke (53.17 +/- 7.52 years old) participated of a gait training program with BWS during overground walking, and were evaluated before and after the gait training period. In both evaluations, individuals were videotaped walking at a self-selected comfortable speed with no BWS. Measurements were obtained for mean walking speed, step length, stride length and speed, toe-clearance, durations of total double stance and single-limb support, and minimum and maximum foot, shank, thigh, and trunk segmental angles.Results: After gait training, individuals walked faster, with symmetrical steps, longer and faster strides, and increased toe-clearance. Also, they displayed increased rotation of foot, shank, thigh, and trunk segmental angles on both sides of the body. However, the duration of single-limb support remained asymmetrical between each side of the body after gait training.Conclusions: Gait training individuals with chronic stroke with BWS during overground walking improved walking in terms of temporal-spatial parameters and segmental angles. This training strategy might be adopted as a safe, specific and promising strategy for gait rehabilitation after stroke.
