Caracterização de pacientes com acidente vascular encefálico em atendimento fisioterapêutico em uma universidade pública / Characterization of patients with encephalic vascular accident in physiotherapeutic care in a public university / Caracterización de pacientes con accidente vascular encefálico en atención fisioterapéutica en una universidad pública

O acidente vascular encefálico (AVE) pode levar a alterações funcionais nas áreas sensitiva, motora, cognitiva e de comunicação. Ocorre através de alterações vasculares do encéfalo, originadas de uma suspensão do fluxo sanguíneo que causa danos celulares irreversíveis, podendo ser dividido em isquêmico ou hemorrágico. O objetivo deste estudo foi identificar o perfil epidemiológico e clínico dos pacientes com acidente vascular encefálico atendidos pela fisioterapia em uma clínica escola de instituição pública na região Centro-Oeste do Brasil. Trata-se de um estudo de corte transversal, descritivo, com abordagem quantitativa. Após aprovação do Comitê de Ética, foram tabulados e analisados os dados dos prontuários, através de um formulário estruturado no programa Excel. Os resultados mostraram que, dos 138 indivíduos, 60,15% eram do sexo masculino, e a idade média foi de 59,53 anos. De acordo com a etiologia, 45,3% sofreram AVE isquêmico; 52,5% possuíam hemiplegia à direita, e 16,55% tiveram múltiplos AVE; 78,98% eram hipertensos; 97,1% utilizavam medicamentos. Em relação ao diagnóstico funcional, a maioria possuía déficit de equilíbrio (39,9%); o objetivo fisioterapêutico mais frequente foi melhorar a amplitude de movimento (96,4%), e a conduta prevalente foi o alongamento (65,9%). Concluiu-se que como a incidência de AVE na população e o desenvolvimento de tecnologias assistivas vêm aumentando a cada dia, menos pacientes morrem por conta do AVE, por isso, faz-se necessário o desenvolvimento de estratégias de prevenção primária, como campanhas educativas, além da prevenção secundária, que por meio da fisioterapia precoce, pode reduzir a proporção de pacientes com incapacidades e melhorar a funcionalidade desses indivíduos.

Stroke can lead to functional changes in the sensory, motor, cognitive and communication areas. It occurs through vascular alterations of the brain originated from a suspension of the blood flow that causes irreversible cellular damages, being able to be divided into ischemic or hemorrhagic. This study aimed to identify the epidemiological and clinical profile of stroke patients cared at physical therapy teams in a public institution school in the Midwest region of Brazil. This is a cross-sectional, descriptive study with a quantitative approach. After approval by the Ethics Committee, the data of the medical records were tabulated and analyzed using a form structured in the Excel program. The results showed that of the 138 individuals, 60.15% were males and the mean age was 59.53 years. According to the etiology, 45.3% suffered from ischemic stroke; 52.5% had right hemiplegia, and 16.55% had multiple strokes; 78.98% were hypertensive; 97.1% used drugs. Regarding the functional diagnosis, most patients had an equilibrium deficit (39.9%); the most frequent physiotherapeutic objective was to improve range of motion (96.4%), and the prevalent conduct was elongation (65.9%). In conclusion, although the incidence of stroke in the population and the development of assistive technologies are increasing each day, fewer patients die due to stroke, therefore, it is necessary to develop primary prevention strategies such as educational campaigns, in addition to of secondary prevention that, through early physiotherapy, can reduce the proportion of patients with disabilities and improve the functionality of these individuals.

Effects of backpack load and positioning on nonlinear gait features in young adults.

Overloaded backpacks can cause changes in posture and gait dynamic balance. Therefore, the aim of this study was to assess gait regularity and local dynamic stability in young adults as they carried a backpack in different positions, and with different loads. Twenty-one healthy young adults participated in the study, carrying a backpack that was loaded with 10 and 20% of their body weight (BW). The participants walked on a level treadmill at their preferred walking speeds for 4 min under different conditions of backpack load and position (i.e. with backpack positioned back bilaterally, back unilaterally, frontally or without a backpack). Results indicate that backpack load and positioning significantly influence gait stability and regularity, with the exception of the 10% BW bilateral back position. Therefore, the recommended safe load for school-age children and adolescents (10% of BW) should also be considered for young adults. Practitioner summary: Increase in load results in changes in posture, muscle activity and gait parameters, so we investigated the gait adaptations related to regularity and stability. Conditions with high backpack loads significantly influenced gait stability and regularity in a position-dependent manner, except for 10% body weight bilateral back position.

Effects of backpack loads and positions on the variability of gait spatiotemporal parameters in young adults

Abstract Introduction: People carry backpacks of different weight in different positions every day. The effects of backpack wearing under different loads and positions were assessed according to the gait's spatiotemporal parameters and their variability in young adults. Methods Twenty-one subjects performed trials of 4 min in the conditions: control condition with no backpack; bilateral back load consisting of 10% body weight (BW); bilateral back load of 20% BW (B20); unilateral load of 10% BW; unilateral load with 20% BW (U20); bilateral frontal load with 10% BW; bilateral frontal load with 20% BW. Results Step length (SL) and step frequency (SF) show that frontal conditions differed from others as seen in B20. Gait cycle phases showed an increase in the B20 condition for double stance phase and stance phase, swing phase presented reduction in the B20 condition. There were significant main effects in position for SL, SF, and walk ratio, in load only for stride width. The highest variability of spatiotemporal parameters occurred in the U20 condition. All load conditions with 20% BW showed a greater variability when compared to the 10% BW counterpart. Conclusion We concluded that young adults can cope with up to a 15% BW load under a bilateral back position, but in the frontal position not even a 10% BW load was proven to be a safe limit. 20% BW loads should be avoided in any position. These recommendations may assure increased gait stability, decreased trunk forward lean and decreased muscle activation and fatigue reducing back pain occurrence.

Local dynamic stability and gait variability during attentional tasks in young adults.

Cell phone use while walking may be a cognitive distraction and reduce visual and motor attention. Thus, the aim of this study was to verify the effects of attentional dual-tasks while using a cell phone in different conditions. Stability, regularity, and linear variability of trunk kinematics, and gait spatiotemporal parameters in young adults were measured. Twenty young subjects of both genders were asked to walk on a treadmill for 4min under the following conditions: (a) looking forward at a fixed target 2.5m away (walking); (b) talking on a cell phone with unilateral handling (talking); (c) texting messages on a cell phone with unilateral handling (texting); and (d) looking forward at the aforementioned target while listening to music without handling the phone (listening). Local dynamic stability measured in terms of the largest Lyapunov exponent decreased while handling a cell phone (talking and texting). Gait variability and regularity increased when talking on a cell phone, but no variable changed in the listening condition. Under all dual-task conditions, there were significant increases in stride width and its variability. We conclude that young adults who use a cell phone when walking adapt their gait pattern conservatively, which can be because of increased attentional demand during cell phone use.

Linear and Nonlinear Gait Features in Older Adults Walking on Inclined Surfaces at Different Speeds.

This study evaluated linear and nonlinear gait features in healthy older adults walking on inclined surfaces at different speeds. Thirty-seven active older adults (experimental group) and fifty young adults (control group) walked on a treadmill at 100% and ±20% of their preferred walking speed for 4 min under horizontal (0%), upward (UP) (+8%), and downward (DOWN) (-8%) conditions. Linear gait variability was assessed using the average standard deviation of trunk acceleration between strides (VAR). Gait stability was assessed using the margin of stability (MoS). Nonlinear gait features were assessed by using the maximum Lyapunov exponent, as a measure of local dynamic stability (LDS), and sample entropy (SEn), as a measure of regularity. VAR increased for all conditions, but the interaction effects between treadmill inclination and age, and speed and age were higher for young adults. DOWN conditions showed the lowest stability in the medial-lateral MoS, but not in LDS. LDS was smaller in UP conditions. However, there were no effects of age for either MoS or LDS. The values of SEn decreased almost linearly from the DOWN to the UP conditions, with significant interaction effects of age for anterior-posterior SEn. The overall results supported the hypothesis that inclined surfaces modulate nonlinear gait features and alter linear gait variability, particularly in UP conditions, but there were no significant effects of age for active older adults.

Gait stability, variability and complexity on inclined surfaces.

This study evaluated the gait stability, variability, and complexity of healthy young adults on inclined surfaces. A total of 49 individuals walked on a treadmill at their preferred speed for 4min at inclinations of 6%, 8%, and 10% in upward (UP) and downward (DOWN) conditions, and in horizontal (0%) condition. Gait variability was assessed using average standard deviation trunk acceleration between strides (VAR), gait stability was assessed using margin of stability (MoS) and maximum Lyapunov exponent (λs), and gait complexity was assessed using sample entropy (SEn). Trunk variability (VAR) increased in the medial-lateral (ML), anterior-posterior, and vertical directions for all inclined conditions. The SEn values indicated that movement complexity decreased almost linearly from DOWN to UP conditions, reflecting changes in gait pattern with longer and slower steps as inclination increased. The DOWN conditions were associated with the highest variability and lowest stability in the MoS ML, but not in λs. Stability was lower in UP conditions, which exhibited the largest λs values. The overall results support the hypothesis that inclined surfaces decrease gait stability and alter gait variability, particularly in UP conditions.

Análise da ativação neuromuscular do vasto medial oblíquo e vasto lateral com o uso da bandagem funcional / Analysis of neuromuscular activation of the vastus medialis obliquus and vastus lateralis with the use of functional taping

Alterações musculares e anatômicas são em sua maioria responsáveis pela síndrome patelofemoral (SDPF). Sabendo que a musculatura do quadríceps é de grande importância na estabilização da patela, questiona-se como o músculo Vasto Medial Oblíquo (VMO) influencia na estabilizaçãopatelar evitando a SDPF. Muitos pesquisadores tem investigado o uso da bandagem funcional como meio de ativação muscular. Objetivo: O presente estudo teve como objetivo analisar o uso da bandagem como meio de ativação do VMO no exercício de agachamento. Método: A atividade dos músculos VMO e Vasto lateral (VL) foi avaliada através de eletromiografia durante o agachamento com adução e o agachamento com o uso de bandagem. A amostra composta por 39 indivíduos foi dividida em quatro grupos: indivíduos do sexo masculino sedentários e atletas, eindivíduos do sexo feminino sedentárias e atletas. Resultados: Embora tenha sido encontrada uma maior ativação do VMO em relação ao VL, com a presente metodologia e variáveis estudadas, não foi possível demonstrar diferença estatística entre os grupos nos agachamentos com e sem o uso da bandagem. No entanto, é importante ressaltar que a ausência de diferença na ativação do VMO durante o agachamento com adução e com bandagem sugerem um efeito positivo e facilitador da bandagem na ativação muscular. Este resultado é muito importante no tratamento de lesões agudas onde o movimento ativo está limitado. Conclusão: Sugere-se a execução de novos estudos aonde outros parâmetros da eletromiografia e estimulação reflexa sejam abordados, a fim de investigar o real papel da bandagem funcional na ativação muscular.

Muscular and anatomical changes are mostly responsible for patella femoral syndrome (PFPS). Knowing that the quadriceps muscles are very important in stabilizing the patella, studies have questioned the influence of the Vastus Medialis Obliquus (VMO) in the patellar stabilization avoiding the PFPS. Many researchers have investigated the use of taping as a means of muscleactivation. Objective: The present study aimed to analyze the use of functional taping to activate the VMO during the squat exercise. Method: The activity of the VMO and Vastus Lateralis (VL) was assessed by electromyography during squats and squats with adduction using functional taping. The sample, composed of 39 individuals, was divided into four groups: males and females, both separated into sedentary and athletic types. Results: Although greater activation of the VMO has been found in comparison with the VL, with the applied methodology and variables, we could not demonstrate a statistical difference between groups in squats with and without the use of functional taping. However, it is important to emphasize that the lack of difference in the activation of VMO during squats with adduction and taping suggests a positive effect of the taping in muscleactivation. This result is very important in the treatment of acute injuries where active movement is limited. Conclusion: Future studies should be done with other electromyography parameters and reflex activation in order to investigate the actual role of functional taping in muscle activation.

Estudo comparativo da atividade do sistema nervoso autônomo através da variabilidade da frequencia cardíaca em trabalhadores noturnos e diurnos / Comparartive study of the independent nervous system activity through the heart rate variability in nocturnal and diurnal workers

O estudo tem como objetivo comparar as alterações físicas entre os trabalhadores diurnos e noturnos. A alteração avaliada foi a variabilidade da frequência cardíaca através do Nerve Express. Também avaliamos a qualidade de vida dos indivíduos através de questionários respondidos antes dos testes. Mensuramos o quanto a ausência do sono noturno influencia na qualidade de vida das pessoas. Percebemos que os indivíduos trabalhadores do período noturno apresentaram melhores resultados quando avaliados em relação à variabilidade da frequência cardíaca, apesar de nos questionários demonstrarem uma maior insatisfação com a qualdiade do sono. Já quando questionados em relação à qualidade de vida ambos os grupos demonstram em sua maioria estarem satisfeitos. Acreditamos que os resultados possuem relação direta com o fato de não possuírem a presença direta de seus superiores.

The study has as objective to compare the physical alterations between the diurnal and nocturnal workers. the alteration evaluated ws the heart variability through nerve express. We also evaluated the quality of life of the individuals through questionnaires answered before the tests. We were able to measure how much the absence of nocturnal sleep influences in the quality of life of life of the people. We realized that the industrious individuals of the nocturnal period presented better results when evaluated regarding the heart variability, despite of in the questionnaires they showed a bigger dissatisfaction with the quality of the sleep. When they were questioned regarding the quality of life, both groups showed, in their majority is satisfied. We believe that the results have straight relation with the fact of the nocturnal workers work in a rhythm less accelerated than the diurnal one, by be not commercial schedule and of not have the straight presence of his superiors.
