Injuries may cause unilateral deterioration of brain areas related to postural control resulting in lateralized motor disability with abnormal asymmetry in weight-bearing distribution. Although overloading toward the nonaffected limb has been described as the preferred posture among individuals with hemiparesis, characterization of the weight-bearing asymmetry is poorly and indirectly described. Therefore, this study aimed to describe weight-bearing distribution during upright stance, establishing criteria to consider asymmetry in hemiparesis when analyzed within the limits defined by controls matched by age and gender. Forty subjects with (n = 20) or without hemiparesis (n = 20) were included in procedures to record weight-bearing values between hemibodies, and these values were used to calculate a symmetry ratio. Control presented 95% confidence interval (CI) of the mean for symmetry ratio ranging from 0.888 to 1.072, defining limits to symmetry. Four subjects with hemiparesis (20%) had symmetry ratios inside limits defined by controls (i.e., weight-bearing symmetrically distributed), and 11 (55%) subjects without hemiparesis showed symmetry ratios outside the limits, suggesting asymmetrical weight-bearing distribution. It was concluded that asymmetry, when present in a control group, was more frequently overloading nonpredominantly used hemibody (nondominant side), differing from a hemiparesis group commonly forced to assume the nonaffected side as the predominantly used hemibody and where the overload was observed.

Avaliação da Simetria e Transferência de Peso (ASTP) foi indicada para se fazer associação entre simetria e atividades funcionais nas hemiparesias, apontando simétricos como mais capacitados. Contudo, tais relações não são claras e divergem com evidências que sugerem assimetrias como estratégias funcionais. Assim, objetivou-se verificar se as medidas subjetivamente determinadas pela ASTP concordam com medidas calculas pela descarga de peso entre os pés. Realizou-se estudo observacional do tipo transversal para amostra de sujeitos com hemiparesia (n=20) pareados por idade e gênero a controles (n=20). Os participantes submeteram-se a procedimentos para obtenção de escore determinado pela ASTP e para cálculo da razão de simetria (RS) na descarga de peso entre os pés obtido por meio de duas balanças digitais. Os resultados obtidos pela ASTP identificaram apenas um sujeito com hemiparesia apresentando simetria, dentre os quatro sujeitos identificados pela RS como simétricos. Ainda, a ASTP não diferenciou assimetrias com sobrecarga para o lado afetado e apresentou correlação significativa somente quando os escores foram analisados com os valores de RS<1(sobrecarga para o lado não afetado). Conclui-se que a ASTP não foi concordante em identificar sujeitos hemiparéticos com descarga de peso compatível com simetria. Ainda, não identificou sobrecargas para o lado afetado que poderia conduzir a análises equivocadas da associação entre simetria e desempenho funcional.

Preserved functions and structures related to movement and advantages in interpersonal interactions, public services and healthy policies could be used to guide therapy and to prevent rehospitalisation commonly observed in chronic stroke survivals.

First designed as an alternative method of assessing balance and susceptibility to falls among elderly, the Functional Reach Test (FR) has also been used among patients with hemiparesis. Then this study aimed to describe the intra-and interrater and the test/re-test reliability of the FR measure in subjects with and without hemiparesis while verifying anthropometric influences on the measurements. The FR was administered to a sample of subjects with hemiparesis and to a control group that was matched by gender and age. A two-way analysis of variance was used to verify the intra-rater reliability. It was calculated using the differences between the averages of the measures obtained during single, double or triple trials. The intra-class correlation coefficient (ICC) was utilized and data plotted using the Bland-Altman method. Associations were analyzed using Pearson's correlation coefficient. In general, the intra-rater analysis did not show significant differences between the measures for the single, double or triple trials. Excellent ICC values were observed, and there were no significant associations with anthropometric parameters for the hemiparesis and control subjects. FR showed good reliability for patients with and without hemiparesis and the test measurements were not significantly associated with the anthropometric characteristics of the subjects.

Introduction: Cerebrovascular diseases result in sensorymotor deficits disturbing postural control that is observed by weightbearing asymmetries commonly named as hemiparesis. Besides hemiparetic impairments, first observed after stroke, many studies have pointed cardiac failure and risk of sudden death as the main factors responsible for death of stroke survivors. This case series characterized weightbearing asymmetries and heart rate variability, and describes relationships between these parameters in hemiparesis. Case Series: Five Brazilian male subjects with chronic hemiparesis acquired after ischemic stroke in the middle cerebral artery were selected to study heart rate variability obtained by Root
