Validation and reproducibility of the Glittre activities of the daily living test for evaluation of functional capacity after a stroke.

METHODS: Thirty patients with hemiparesis stemming from a stroke and 20 healthy peers were evaluated. Reproducibility was determined using the intraclass correlation coefficient (ICC), standard measurement error (SME), minimum detectable change (MDC), and Bland-Altman analysis. For construct validity, the Glittre ADL test was correlated with the Six-Minute Walk Test (6MWT), Timed Up and Go Test (TUG), and Functional Independence Measure (FIM), and analyzed based on convergent validity and the comparison of known groups (stroke survivors and healthy peers). RESULTS: Intra- and inter-observer reliability were excellent (ICC3,1 = 0.98; 0.96, respectively). Intra-observer SME ranged from 0.27 to 0.31 minutes and inter-observer SME was 0.45 minutes. Intra-observer MDC ranged from 1.44 to 1.54 minutes and inter-observer MDC was 1.86 minutes. Strong statistically significant correlations were found between time on the Glittre ADL test and time on the 6MWT (rh = -0.91; p < .001) and TUG test (rh = 0.82; p < .001), whereas a moderate correlation was found with the FIM (rh = -0.47; p < .008). CONCLUSIONS: The Glittre ADL test is valid for assessing functional capacity in stroke patients. It demonstrated good convergent and construct validity and excellent intra- and inter-observer reproducibility.

Effect of transcranial direct current stimulation and multicomponent training on functional capacity in older adults: protocol for a randomized, controlled, double-blind clinical trial.

INTRODUCTION: When physical activity contains training of at least three components such as balance, coordination and strength, among others, it is called multicomponent training. This type of training is recommended for improving the functional capacity in elderly individuals but has no lasting effects. The association of transcranial direct current stimulation (tDCS) with other types of therapy has been shown to facilitate the enhancement and prolongation of therapy outcomes. AIM: The objective of this study is to evaluate the effect of multicomponent training associated with active or sham tDCS on the performance of functional capacity in the elderly before treatment, after treatment and 30 days after the end of treatment. The secondary objective will be to correlate the performance of the primary outcome (functional capacity assessed by the Glittre Daily Life Activity Test) with walking capacity (by 6-min walk test), balance (with the mini-Balance Evaluation Systems Test), functional independence (by the Functional Independence Measure) and quality of life (with the World Health Organization Quality of Life Instrument). METHODS: Twenty-eight elderly people from the community will participate in the study, and will be randomized into two groups: 1) multicomponent training associated with active tDCS; and 2) multicomponent training associated with sham tDCS. The multicomponent training sessions will be held twice a week for 12 weeks, totaling 24 sessions. The tDCS will be administered over the dominant dorsolateral prefrontal cortex at the same time as multicomponent training, with an intensity of 2 mA, for 20 min. The evaluations will be made pretraining, after 24 training sessions and 30 days after the end of the training. DISCUSSION: We hypothesize that tDCS, when associated with multicomponent training, can potentiate and prolong the effects of this training on the functional capacity of the elderly. If this hypothesis is confirmed, this protocol may contribute to a longer-lasting physical rehabilitation of the elderly, encouraging them to maintain their independent daily activities for longer. TRIAL REGISTRATION: The study was registered in the Brazilian Clinical Trial Registry (RBR-2crd42) and received approval from the Human Research Ethics Committee of University Nove de Julho, São Paulo, Brazil (process number 3.077.953).

Immediate effect of transcranial direct current stimulation combined with functional electrical stimulation on activity of the tibialis anterior muscle and balance of individuals with hemiparesis stemming from a stroke.

[Purpose] The aim of the present study was to evaluate the immediate effects of transcranial direct current stimulation (tDCS) and functional electrical stimulation (FES) on activity of the tibialis anterior muscle (TA) and static balance of individuals with hemiparesis stemming from stroke. [Subjects and Methods] A randomized, double-blind, crossover, clinical trial conducted with 30 individuals with chronic post-stroke hemiparesis. Median frequency of electrical activity of the TA were determined using electromyography in five contractions concentrics and Static balance (body sway velocity and frequency), both before and immediately after the intervention. The participants were submitted to four 20-minute intervention protocols with 48-hour interval: anodal tDCS + sham FES; sham tDCS + active FES; anodal tDCS + active FES and sham tDCS + sham FES. Anodal tDCS was administered over C3 or C4, the cathode was positioned in the supraorbital region on the contralateral side and FES was administered to the affected TA. [Results] No significant differences among the protocols were found regarding electrical activity of the TA and static balance. [Conclusion] The results demonstrate that tDCS alone or in combination with FES had no immediate effect on electrical activity of the TA and static balance of the 30 individuals analyzed.

Efeito do enfaixamento em oito no equilíbrio estático e distribuição de pressão plantar após acidente vascular encefálico / Efecto del vendaje en ocho para el equilibrio estático y la distribución de la presión plantar pos-accidente cerebrovascular / Effect of eight-point binding in static balance and distribution of plantar pressure after stroke

RESUMO O pé equinovaro é uma sequela comum após o Acidente Vascular Encefálico (AVE), as alterações biomecânicas do tornozelo hemiparético interferem no equilíbrio e na assimetria corporal após o AVE. Diversos recursos são utilizados para minimizar essas alterações, entre estas, destaca-se o enfaixamento em oito, que visa fornecer informações proprioceptivas e promover o alinhamento biomecânico do tornozelo, agindo assim contra os mecanismos que levam ao pé equinovaro. Entretanto, ainda não há evidências do efeito do enfaixamento em oito no equilíbrio estático e na distribuição da pressão plantar do tornozelo hemiparético. Diante disso, o objetivo deste estudo foi avaliar o efeito imediato do enfaixamento em oito no equilíbrio estático e distribuição de pressão plantar de indivíduos com hemiparesia em decorrência do AVE. Para tanto, avaliou-se 30 indivíduos com hemiparesia crônica que foram avaliados em três momentos distintos: sem enfaixamento, com enfaixamento e após cinco minutos de uso do enfaixamento. Os indivíduos foram posicionados sobre uma plataforma de força para avaliação do equilíbrio e pressão plantar. Para análise dos dados utilizou-se o teste ANOVA para medidas repetidas, assumindo risco α ≤0,05. Não foi evidenciada diferença estatisticamente significante no equilíbrio estático e na distribuição da pressão plantar após o uso do enfaixamento em oito em nenhum dos momentos avaliados neste estudo. Conclui-se que uma única aplicação do enfaixamento em oito não é capaz de gerar mudanças clínicas no equilíbrio estático e na distribuição plantar. Sugere-se que outros estudos sejam realizados para analisar o efeito do uso prolongado do enfaixamento em oito.

RESUMEN El pie equinovaro es una secuela pos-accidente cerebrovascular (ACV), las alteraciones biomecánicas del tobillo hemiparético interfieren el equilibrio y la asimetría corporal pos-ACV. Se utilizan diversos recursos para minimizarlas, en los cuales se destaca el vendaje en ocho, que tiene el propósito de fornecer informaciones propioceptivas y de promocionar el alineamiento biomecánico del tobillo, actuando en contra de mecanismos que dejan el pie equinovaro. Sin embargo, no hay evidencias todavía del efecto del vendaje en ocho para el equilibrio y la distribución de la presión plantar del tobillo hemiparético. Teniendo en cuenta eso, este estudio tuvo el objetivo de evaluar el efecto inmediato del vendaje en ocho para el equilibrio estático y la distribución de la presión plantar de sujetos con hemiparesia debido al ACV. Para ello, se evaluaron 30 sujetos hemiparéticos crónicos en tres momentos distintos: sin vendaje, con vendaje y tras cinco minutos utilizando el vendaje. Los participantes fueron puestos en una plataforma de fuerza para evaluar el equilibrio y la presión plantar. Para análisis de datos se utilizó el test ANOVA para medidas repetidas, asumiendo el riesgo de α ≤0,05. No hubo diferencias estadísticamente significativas en el equilibrio estático y en la distribución de la presión plantar tras el uso del vendaje en ocho en ningún de los momentos evaluados en este estudio. Se concluye que una sola aplicación del vendaje en ocho no es suficiente para producir cambios clínicos en el equilibrio estático y en la distribución plantar. Se recomienda que sean realizadas otras investigaciones para evaluar el efecto a largo plazo del vendaje en ocho.

ABSTRACT The equinovarus foot is a common sequela after a cerebrovascular accident (CVA), the biomechanical changes of hemiparetic ankle interfere in balance and body asymmetry after a stroke. Several resources are used to minimize these changes, among them stands out the eight-point binding, which aims to provide proprioceptive information and promote the biomechanical alignment of the ankle, thus acting against the mechanisms leading to equinovarus foot. However, there is still no evidence of the effect of eight-point binding in static balance and plantar pressure distribution of the hemiparetic ankle. Thus, the aim of this study was to evaluate the immediate effect of eight-point binding on static balance and plantar pressure distribution in patients with hemiparesis due to stroke. To this end, we evaluated 30 subjects with chronic hemiparesis who were evaluated at three different times: without bandaging, with bandaging, and after five minutes of use of bandaging. The subjects were positioned on a force platform to assess balance and plantar pressure. For data analysis we used ANOVA for repeated measures, assuming α≤0.05 risk. There was no statistically significant difference in static balance and plantar pressure distribution after the use of eight-point binding in any of the evaluated moments in this study. It follows that a single application of the eight-point binding is not able to generate clinical changes in static balance and plantar distribution. It is suggested that further studies need to be conducted to examine the effect of prolonged use of eight-point binding.
