Abstract Background There is no consensus among tools for assessing frailty. Objective To evaluate the prevalence of frailty according to different tools in patients referred for elective valve cardiac surgery. Methods This is a cross-sectional study. All patients were ≥ 18 years of age, clinically stable. The following patients were excluded: those unable to perform the tests because of physical, cognitive, or neurological limitations; those requiring non elective/emergency procedures or hemodynamic instability. During the preoperative cardiology visit, frailty was assessed by the Short Physical Performance Battery (SPPB), the Frailty Deficit Index (FDI), handgrip strength, and gait speed 3m. For the entire analysis, the statistical significance was set at 5%. Results Our cohort consisted of 258 subjects. From the total cohort, 201 were ≤ 70 years of age (77.9%), the predominant etiology according to rheumatic disease (50.7% vs 8.8%; p=0.000) with double mitral lesion (24.9% vs 0%; p=0.000). Frailty was present in 32.9% according SPPB, 29.1% with reduced muscular strength. and 8.9% with FDI. Handgrip strength was weaker in elderly patients (26.7 vs 23.6; p=0.051) and gait speed was lower in the younger group, in which 36% were considered frail (36% vs 14%; p=0.002). Variables associated with frailty were age ≥ 70 years, female gender, aortic stenosis, and regurgitation. Conclusion Frailty in adult patients who will have elective heart valve surgery is present even in the younger groups, although the older group with comorbidities are more frail. Frailty was more clearly shown by the SPPB than by the FDI and handgrip tests.

ABSTRACT Introduction: We applied three-dimensional gait analysis to assess the effects of enhanced active contraction of the transversus abdominis (EACTA) during walking. We sought to evaluate the effect of EACTA during walking in order to improve walking quality. Methods: Thirty college students were recruited and trained to perform EACTA during walking. We examined gait parameters under different conditions, including EACTA and habitual ACTA (natural walking with mild contraction of the feedforward mechanism of ACTA, HACTA) during walking using three-dimensional gait analysis. We compared differences in gait parameters under the two walking conditions using SPSS 16.0 statistical software. Results: The following gait parameters were significantly lower under EACTA conditions than under HACTA conditions (P < 0.05): stance phase, 59.151% ± 1.903% vs. 59.825% ± 1.495%; stride time, 1.104 s ± 0.080 s vs. 1.134 s ± 0.073 s:; stance time, 0.656 s ± 0.057 s vs. 0.678 s ± 0.053 s; and swing time, 0.447 s ± 0.028 s vs. 0.454 s ± 0.031 s, respectively. Gait parameters single support phase and mean velocity were significantly higher for EACTA than for HACTA conditions (both P < 0.05). Conclusions: Overall, the results revealed that EACTA during walking can improve gait. This method is simple, and EACTA training during walking to improve gait quality in daily life could provide a positive basis for people to strengthen the transverse abdominal muscle. Level of evidence III; Retrospective comparative study .

RESUMEN Introducción: Aplicamos el análisis tridimensional de la marcha para evaluar los efectos del aumento de la contracción activa del músculo transverso del abdomen (EACTA) durante la caminata. Buscamos evaluar el efecto del EACTA durante la caminata para mejorar su calidad. Métodos: Treinta estudiantes universitarios fueron reclutados y entrenados para realizar el EACTA durante la caminata. Examinamos los parámetros de la marcha en diferentes condiciones, incluyendo EACTA y ACTA habitual (caminata natural con leve contracción del mecanismo de feedforward del ACTA, HACTA) durante la caminata usando análisis tridimensional de la marcha. Comparamos las diferencias en los parámetros de la marcha en las dos condiciones de caminata en el software estadístico SPSS 16.0. Resultados: Los siguientes parámetros de marcha fueron significativamente más bajos en la condición EACTA que en condiciones HACTA (P <0,05): fase de apoyo 59,151 ± 1,903% vs 59,825 ± 1,495%, tiempo de zancada 1,104 s ± 0,080 s vs 1,134 s ± 0,073 s, tiempo de apoyo 0,656 s ± 0,057 s vs 0,678 s ± 0,053 s y tiempo de balance 0,447 s ± 0,028 s vs 0,454 s ± 0,031 s, respectivamente. Los parámetros de la marcha, fase de apoyo simple y velocidad promedio fueron significativamente mayores en el EACTA que en las condiciones HACTA (ambos P <0,05). Conclusiones: En general, los resultados revelaron que el EACTA durante la caminata puede mejorar la marcha. Este método es simple, y el entrenamiento del EACTA durante la caminata para mejorar la calidad de la marcha en la vida diaria puede ser una base positiva para el fortalecimiento del músculo transverso del abdomen. Nivel de evidencia III; Estudio retrospectivo comparativo .

O objetivo deste estudo foi analisar as possíveis relações entre a variável antropométrica comprimento dos membros inferiores e de passada na marcha, com valores naturais e normalizados, em velocidade auto-selecionada e acrescida de 50%, em indivíduos adultos jovens. Foram avaliados 32 sujeitos hígidos adultos entre 18-25 anos. Os deslocamentos corporais nas duas velocidades foram registrados através da técnica de cineantropometria, utilizando o software Skillspector® para quantificar o comprimento da passada entre as médias dos dados normalizadas e não-normalizadas, do segmento direito e do segmento esquerdo. A comparação entre os valores médios das passadas normalizadas e não-normalizadas, nas diferentes velocidades, foi realizada por meio do teste t student (p < 0,05), assim como o grau de associação entre o comprimento da passada e o comprimento do membro inferior, realizada pelo teste de correlação de Pearson (p < 0,05). Sendo assim, nosso estudo constatou uma correlação positiva entre as variáveis estudadas, nas duas velocidades e, uma diferença entre a passada com dados normalizados e não normalizados, em ambas as velocidades. (AU)

The aim of this study was to analyze the possible relationships between the anthropometric variable length of the lower limbs and gait stride, with natural and normalized values, at self-selected speed and increased by 50%, in young adult individuals. 32 healthy adult subjects aged 18-25 years were evaluated. Body movements at both speeds were recorded using the kinanthropometry technique, using the Skillspector® software to quantify the stride length between the normalized and nonnormalized data averages for the right and left segments. The comparison between the mean values of normalized and non-normalized strides, at different speeds, was performed using the Student t test (p < 0.05), as well as the degree of association between stride length and lower limb length, performed by the Pearson correlation test (p < 0.05). Thus, our study found a positive correlation between the variables studied, at both speeds, and a difference between the stride with normalized and non-normalized data, at both speeds. (AU)

Introdução: A marcha pode ser definida como um padrão cíclico, na postura bípede, que utiliza os membros inferiores para propulsão do corpo. No campo da Neurologia, a marcha no exame físico representa sinais na avaliação neurológica, que auxiliam no fechamento de diagnósticos. No ambiente clínico, em especial nos consultórios, o refinamento da avaliação da marcha fica restrita a experiência do clínico, pois o espaço muitas vezes é reduzido, o tempo inadequado para avaliação. Poucos relatos na literatura abordaram a referida questão. Objetivo: Discutir os principais pontos da análise de marcha de interesse dos neurologistas, no consultório. Metodologia: Nessa revisão narrativa, foram levantados 32 artigos e, aplicados os critérios de elegibilidade, foram selecionados 6 artigos. A avaliação da marcha no consultório deve respeitar critérios, pois pode acarretar vieses dos parâmetros da marcha e dificultar a análise global. Conclusão: Por isso, há necessidade de maiores discussões, no âmbito do consultório, para melhor avaliar os parâmetros da marcha. (AU)

Introduction: Gait can be defined as a cicle pattern in biped posture that use to lower limb to body propulse. In Neurology, the physical exam of gait represents a neurological signal. This fact can help in the diagnosis conclusion. In a clinical setting and medical office, the critical evaluation is restricted to the physician´s expertise. The space of doctor´s room is often reduced and inappropriate time for evaluation. Objective: This study aimed to discuss the main points of gait analysis in neurological outpatients. Methods: In this narrative review, 32 articles were analyzed, and after included criteria, 6 articles were selected. In neurology medical office must respected criteria to no promote bias of gait parameter and complicate global assessment. Conclusion: Therefore, there is a need for further discussions, within the scope to better assess the gait parameters. (AU)

Abstract Introduction: Knee osteoarthritis is a degenerative and inflammatory disease that causes skeletal muscle dysfunction and induces limitation of functional activities, such as gait. Objective: To assess the relationship between gait speed and functional performance in elderly women with knee osteoarthritis. Methods: 38 elderly women were divided into two groups: knee osteoarthritis group (KOAG) (n = 24, 68 ± 4.42) and control group (CG) (n = 14, 66.35 ± 3.54). Gait speed data was assessed through Qualisys system and functional performance through a checklist of the International Classification of Functioning, Disability and Health (ICF). Results: Comparing with CG (p < 0.05), KOAG patients had lower gait speed (p = 0.004) and worse functional performance in d4500 (walking short distances), d4501 (walking long distances), d4502 (walking on different surfaces), and d4503 (walking around obstacles) ICF categories. By associating gait speed and functional performance in KOAG, significant differences were found in the d4500 (p = 0.019) and d4501 (p = 0.035) categories, but none for either the d4502 (p = 0.511) or d4503 (p = 0.076) categories. Gait speed was negatively correlated with d4500 (rho = -0.585, p = 0.003), d4501 (rho= -0.552, p = 0.005), and d4502 (rho = -0,548, p = 0,006). Conclusion: Gait speed is related to functional performance in elderly women with knee osteoarthritis for the activities of walking short distances, walking long distances, and walking on different surfaces. However, it seems that gait speed is not related to walking around obstacles.

Resumo Introdução: A osteoartrite de joelho (OJ) é uma doença degenerativa e inflamatória que causa incapacidade musculoesquelética, acarretando limitação de atividades funcionais como a marcha. Objetivo: Avaliar a relação entre velocidade da marcha e desempenho funcional em idosas com OJ. Métodos: Trinta e oito idosas foram divididas em grupo com osteoartrite de joelho (GOAJ) (n = 24, 68 ± 4,42) e grupo controle (GC) (n = 14, 66,35 ± 3,54) e avaliadas quanto à velocidade da marcha, utilizando o sistema Qualisys, e quanto ao desempenho funcional através de um checklist da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF). Resultados: GOAJ apresentou menor velocidade da marcha (p = 0,004) e pior desempenho funcional nas categorias da CIF d4500 (andar distâncias curtas), d4501 (andar distâncias longas), d4502 (andar em superfícies diferentes) e d4503 (andar contornando obstáculos) em comparação ao GC (p < 0,05). Ao associar velocidade da marcha e desempenho funcional do GOAJ, encontrou-se diferenças nas categorias d4500 (p = 0,019) e d4501 (p = 0,035), mas não em relação às categorias d4502 (p = 0,511) e d4503 (p = 0,076). Velocidade da marcha correlacionou-se negativamente com d4500 (rho = - 0,585, p = 0,003), d4501 (rho = -0,552, p = 0,005) e d4502 (rho = -0,548, p = 0,006). Conclusão: Existe relação entre velocidade da marcha e desempenho funcional de idosas com OJ quanto às atividades de andar distâncias curtas e longas e sobre superfícies diferentes; no entanto, a velocidade da marcha parece não interferir na atividade de andar contornando obstáculos.

@#OBJECTIVE: This study aimed to quantitatively define outcomes of corrective surgery in children with various foot deformities. METHODS: We used a retrospective, nonrandomized design. All pediatric patients who underwent pre and post-operative gait analysis and corrective surgery were included. Outcome measures included quantitative gait analysis with temporospatial and kinematic parameters, the Gait Deviation Index, Gillette FAQ, and Hoffer’s criteria. RESULTS:. Five patients with neurogenic and idiopathic deformities underwent corrective surgery at the Philippine General Hospital from 2015 to 2017. Comparison of gait pre and postoperatively show promising outcomes, with improvement in GDI and FAQ levels, despite some of the patients’ need for braces. CONCLUSIONS: Quantitative gait analysis is a suitable method for evaluating surgical outcomes for foot deformity correction. It can be used in combination with functional outcome measures and clinical examination to give an overall picture of a patient’s walking ability.

PURPOSE@#To observe the changes of gait behavior and the expression of wound healing factors of transforming growth factor-β1 (TGF-β1), TGF-β3 and cAMP response element binding protein-1 (CREB-1) during the healing of Achilles tendon in a rat model, and to investigate whether gait analysis can be used to evaluate the tendon healing.@*METHODS@#Achilles tendon of 40 healthy male Sprague-Dawley rats were transected and sutured to establish the Achilles tendon injury (ATI) model. They were randomly divided into 4 groups based on the observational time point at 1, 2, 4 and 6 weeks after injury (n = 10 for each group). Before modeling, 9 rats were randomly selected for CatWalk gait analysis, which contained step cycle, single stance time and average speed. Data were recorded as the normal controls. After then, ATI models were established in the left hind limbs of the all 40 rats (ATI group), while the right hind limbs were only cut and sutured without injury of the Achilles tendon (sham operation group). At 1, 2, 4 and 6 weeks after injury, the gait behavior of the corresponding group of rats (n = 9) as observed and recorded by CatWalk platform. After then, the rats were sacrificed and Achilles tendon of both limbs was harvested. The tendon healing was observed by gross anatomy and histological examination, and the protein and mRNA expression of TGF-β1, TGF-β3, CREB-1 were observed by immunohistochemistry and qPCR. The results of tendon gross grading were analyzed by Wilcoxon rank sum test, and other data were analyzed by one-way analysis of variance among multiple groups.@*RESULTS@#Compared with normal controls, all gait indexes (step cycle, single stance time and average speed) were greatly affected following ATI, which however improved with time. The step cycle was significantly lower at 1, 2 and 4 weeks after ATI (compared with normal controls, all p  0.05). The single stance time of the ATI group was significantly shorter at 1 and 2 weeks after operation ((0.078 ± 0.010) s at 1 week, (0.078 ± 0.020) s at 2 weeks, all p < 0.001) and revealed no significant difference at 4 weeks (p = 0.120). The average speed of ATI group at 1, 2, 4, 6 weeks was significantly lower than that in the normal control group (all p < 0.001). Gross observation showed that the grade of local scar adhesion in ATI group increased significantly at 2, 4 and 6 weeks, compared with the sham operation group (all p < 0.001). Extensive adhesion was formed at 6 weeks after ATI. The results of HE staining showed that the number of fibroblast increased gradually and arranged more orderly in ATI group at 1, 2 and 4 weeks (all p < 0.001), and decreased at 6 weeks, but it was still significantly higher than that of the sham operation group (p < 0.001). Immunohistochemistry showed that the positive expression of TGF-β1, TGF-β3, CREB-1 in ATI group was higher than that in the sham operation group at 4 time points (all p < 0.05), which reached the peak at 2 weeks after operation and decreased at 4 weeks (p = 0.002, p < 0.001, p = 0.041, respectively). The results of qPCR suggested that the mRNA expression of TGF-β1, TGF-β3, CREB-1 in ATI group was higher than that in the sham operation group at all-time points (all p < 0.05), which reached the peak at 2 weeks after operation, decreased at 4 weeks, and significantly decreased at 6 weeks (all p < 0.001).@*CONCLUSION@#Gait behavior indexes are associated with Achilles tendon healing. The study gives an insight of TGF-β1, TGF-β3, CREB-1 changes in the coursing of Achilles tendon healing and these cytokines may be able to be used to regulate the Achilles tendon healing.

O objetivo desse estudo foi verificar a concordância na velocidade da marcha (VM) a partir dos testes de caminhada de seis minutos (6MWT) e de quatro metros (4MWT) em mulheres diabéticas tipo 2 (DM2). Os testes foram realizados antes e após intervenção de 12 semanas com exercícios físicos. O 4MWT foi realizado em espaço de quatro metros, sendo o resultado do teste medido como o tempo gasto (segundos) no percurso. O 6MWT foi realizado em modelo de ir e vir em uma distância de 15 metros e o resultado foi a distância total (metros) percorrida. Os resultados foram padronizados para velocidade de deslocamento (m/s). Para avaliar a concordância (6MWTpré x 4MWTpré) e (6MWTpósx 4MWTpós), utilizou-se o teste de Bland-Altman (B-A) e o coeficiente de concordância de correlação de Lin. O nível de significância aceito para o estudo foi α 5%. Foram medidas 39 mulheres, com idade média de 58,79 ± 10,03 anos e diagnóstico de DM2 a 8,64 ± 8,53 anos. Verificou-se, pelo teste de B-A, diferenças na VM dos testes de -0,001 ± 0,19 m/s (IC95%: -0,37 a 0,37 m/s) no início e 0,02 ± 0,21 m/s (IC95%: -0,39 a 0,42 m/s) ao final e concordância de 0,60 (IC95%: 0,41 a 0,79; p < 0,001) e 0,52 (IC95%: 0,31 a 0,73; p < 0,001) pré e pós, respectivamente, pelo coeficiente de concordância de correlação Lin. Através dos dados obtidos, sugere-se que os dois testes podem ser utilizados para avaliar a VM das mulheres DM2, porém o 6MWT apresentou maior reprodutibilidade para detectar mudanças na VM ao longo do tempo

This study aimed to test the agreement in the gait speed (GS) between the 6-minute walk test and the 4-me-ter gait speed (6MWT - 4MWT) in type 2 diabetic women (T2DM). The tests were performed before and after a 12-week physical exercise intervention. The 4MWT was performed in a space of four meters, with results based on the time spent (seconds) to complete a 4-meter distance. The 6MWT was carried out similar to a yo-yo test in 15 meters and the result was operationalized by the total distance (meters) covered. The results of the tests were standardized as speed (m/s). To evaluate agreements (6MWTbefore x 4MWTbefore) and (6MWTafter x 4MWTafter), Bland-Altman (B-A), and Lin's agreements were used. The level of significance was set at 5%. A total of 39 women were evaluated, mean age 58.79 ± 10.03 years, diagnosis of diabetes at 8.64 ± 8.53 years.The B-A test showed a mean difference in GS of -0.001 ± 0.19 m/s (95%CI: -0.37 to 0.37 m/s) before and 0.02 ± 0.21 m/s (95%CI: -0.39 to 0.42 m/s) after, and Lin's agreements of 0.60 (95%CI: 0.41 to 0.79; p < 0.001) and 0.52 (95%CI: 0.31 to 0.73; p < 0.001) before and after, respectively. Based on our data it is suggested that the two tests can be used to evaluate the GS of T2DM women, but the 6MWT was more reproductible to detect changes in GS over time

This research was carried out to evaluate the effect of mycotoxins on the performance of horses through physiological parameters, and hematology and serum biochemistry analyses. The essay lasted 40 days, with 12 days for adaptation and 28 days of experimentation. In the experimental stage, the horses were distributed in a completely randomized design, with three treatments with four animals each. The treatments used were 0 (control), 50 ppb and 100 ppb of Aflatoxin B1 (AFB1) added to a concentrate in a basal diet. The basal diet contained mycotoxins from feedstuffs naturally contaminated. The exercise test was performed over the 21th day of the experimental stage. The exercise consisted in an interval training test with a warm-up of 17 mins at a trot followed by three gallops of 450m/min. The heart rate was monitored between the gallops. Before the exercise test and immediately after the third gallop, the physiological and blood parameters were evaluated, and continued up to 48 hours after the exercise. The results of the physiological, hematological and biochemical parameters were submitted to analysis of variance (ANOVA) and compared by the Tukey test at 5% of significance. The presence of AFB1 in the diet influenced the alkaline phosphatase activity, which presented higher values in horses fed diet with inclusion of 100 ppb AFB1, suggesting a hepatotoxic activity associated with the others mycotoxins naturally present in the feedstuffs.(AU)

Esta pesquisa foi conduzida para avaliar o efeito de micotoxinas no desempenho de equinos com avaliações fisiológicas e análises hematológicas e da bioquímica sérica. O ensaio durou 40 dias, com 12 dias de adaptação e 28 dias de experimentação. Na fase experimental, os equinos foram distribuídos em delineamento inteiramente casualizado em três tratamentos, com quatro animais cada. Os tratamentos utilizados foram 0 (controle), 50 ppb e 100 ppb de Aflatoxina B1 (AFB1) adicionada ao concentrado de uma dieta basal. A dieta basal continha alimentos naturalmente contaminados por micotoxinas. O teste de desempenho foi executado no 21º dia da fase experimental por meio de teste intervalado consistindo em aquecimento ao trote por 17 minutos, seguido de três galopes de 450m/min. A frequência cardíaca (FC) foi monitorada entre os galopes. Antes do exercício e imediatamente após o terceiro galope, os parâmetros fisiológicos e sanguíneos foram avaliados e continuaram sendo monitorados até 48 horas após o exercício. Os resultados dos parâmetros fisiológicos, hematológicos e bioquímicos foram submetidos à análise de variância (ANOVA) e comparados pelo teste de Tukey a 5% de significância. A presença de AFB1 na dieta influenciou a atividade da fosfatase alcalina, que apresentou valores mais elevadas na dieta com inclusão de 100 ppb de AFB1, sugerindo uma atividade hepatotóxica associada às outras micotoxinas naturalmente presentes nos alimentos.(AU)

Revisión de nuestros hallazgos experimentales sobre la relación entre audición y control motor del equilibrio en usuarios de implantes cocleares (UIC). Se realizó posturografía en 34 UIC en dos condiciones sensoriales:1- Implante encendido (ON). 2- Implante apagado (OFF) Se usó como medida el consumo de energía (CE) de la señal del centro de presión corporal. La marcha se analizó mediante la prueba de 10 m, implementada con: A - implante ON y ruido ambiental (EN), B - Implante ON, EN y Tarea dual cognitiva (DT) y C-implante OFF. Se registró la velocidad de marcha (GV) usando acelerómetros en los pies y la región retrosacra. Estadística: Se utilizaron las pruebas de Wilcoxon y Mann-Whitney y el nivel de significación fue p = 0.05. El análisis de la postura en la adolescencia mostró un ajuste adaptativo, disminuyendo la CE con el IC-ON.p = < 0,05, mientras con el CI-OFF no hubo disminución p => 0,05. En adultos, CI- OFF tuvieron valores más altos de CE en edades mayores, mientras que el CE no se incrementó con la edad con el CI-ON. En la marcha, la GV con el implante ON en EN solo disminuyó en UIC solo en aquellos que estaban implantado después de los 3 años. La UIC implantada antes de esta edad mostró un comportamiento de la marcha similar en comparación con los sujetos con audición normal como control. La información auditiva interviene en la postura y el comportamiento motor de la marcha, hechos que se analizan en esta revisión.

Review of publications of our group about the relationship between the auditory input and the balance motor control in subjects with profound hearing loss and cochlear implant users (UIC). A population of 34 UIC in which posturography in two different sensory information was performed, 1-Implant turned on (ON) giving acoustic information. 2-Implant turned off (OFF) and without auditory input. Energy consumption (CE) of the body center of pressure signal was used as measurement. Gait assessment was analyzed by the 10 m test, implemented with: A- Implant turned ON and environmental noise (EN). B- Implant ON, EN and cognitive dual task (DT) and C- Implant OFF with accelerometers in the feet and sacrum region to measure the gait velocity (GV). Statistics: Wilcoxon and Mann-Whitney test were used and significance level was p=0.05. Posture analysis for different ages in adolescence showed an adaptive adjustment, decreasing the EC significantly when the CI is ON (p<0.05). With the implant turned OFF, changes were not significant (p>0.05). In adults, (implant OFF) had higher values of CE related with age, while the CE did not show increment of CE with age when receiving auditory input with the implant ON. UIC implanted after being 3 years old showed a significant decrease in GV. The UIC implanted before this age showed similar gait behavior compared to normal hearing subjects as control. The auditory information intervenes in posture and gait motor behavior, facts which are analyzed in this review.

Revisão de publicações de nosso grupo sobre a relação entre a entrada auditiva e o controle motor do equilíbrio em indivíduos com perda auditiva profunda e usuários de implante coclear (UIC). Uma população de 34 UIC em que foi realizada a posturografia em duas informações sensoriais diferentes, o 1-Implant ativado (ON) fornece informações acústicas. 2-O implante foi desativado (OFF) e sem entrada auditiva. O consumo de energia (CE) do sinal do centro de pressão corporal foi utilizado como medida. A avaliação da marcha foi analisada pelo teste de 10 m, implementado com: A- Implante ligado e ruído ambiental (EN). B- Implante ON, EN e tarefa dupla cognitiva (TD) e C- Implante OFF com acelerômetros na região dos pés e sacro para medir a velocidade da marcha (GV). Estatísticas: Foram utilizados os testes de Wilcoxon e Mann-Whitney e o nível de significância foi de p = 0,05. A análise da postura para diferentes idades na adolescência mostrou um ajuste adaptativo, diminuindo significativamente a CE quando o IC está ligado (p <0,05). Com o implante desligado, as alterações não foram significativas (p> 0,05). Nos adultos, o (implante OFF) apresentou maiores valores de EC relacionados à idade, enquanto o CE não apresentou incremento do CE com a idade ao receber entrada auditiva com o implante ON. A UIC implantada após os 3 anos de idade mostrou uma diminuição significativa no GV. A UIC implantada antes dessa idade mostrou comportamento de marcha semelhante em relação aos indivíduos com audição normal como controle. As informações auditivas intervêm no comportamento motor da postura e da marcha, fatos analisados nesta revisão.

INTRODUÇÃO: A espasticidade pode ser considerada como uma das mais impactantes alterações secundárias à paralisia cerebral. Nos últimos anos, a Rizotomia Dorsal Seletiva (RDS) tem sido destacada como um procedimento cirúrgico eficaz para o tratamento da espasticidade dos membros inferiores de crianças com paralisia cerebral. OBJETIVOS: Verificar por meio de uma revisão sistemática da literatura os efeitos em médio e longo prazo, da RDS sobre a função motora grossa e a marcha em crianças e adolescentes com paralisia cerebral. Além de averiguar se existe um consenso na literatura sobre os critérios de indicação da RDS. MÉTODOS: Uma pesquisa foi realizada na rede internacional nos bancos de dados de acordo com os seguintes critérios de inclusão: (1) desenho: estudos envolvendo o acompanhamento pós-operatório longitudinal; (2) população: crianças e adolescentes com paralisia cerebral espástica; (3) intervenção: RDS; (4) grupo controle com intervenção diferente ou sem intervenção; (5) desfecho: melhora da função motora, melhora da espasticidade e desempenho da marcha. RESULTADOS: Foi encontrado um total de seis artigos que preencheram os critérios de inclusão e foram utilizados nesta revisão. Nos estudos analisados, foram observadas melhoras significativas na variável cinemática da marcha com diminuição da espasticidade no grupo RDS. CONCLUSÃO: A RDS diminui a espasticidade com efeitos positivos sobre a função motora grossa e a marcha de crianças e adolescentes com paralisia cerebral, porém estudos adicionais são necessários para esclarecer a eficácia da RDS aplicada em grupos musculares de membros inferiores.

INTRODUCTION: Spasticity can be considered one of the most striking alterations secondary to cerebral palsy. In recent years, Selective Dorsal Rhizotomy (SDR) has been highlighted as an effective surgical procedure for the treatment of lower limb spasticity in children with cerebral palsy. OBJECTIVES: To verify through a systematic review of the literature the medium and long-term effects of SDR on gross motor function and gait in children and adolescents with cerebral palsy. Secondarily, to verify if there is a consensus in the literature on the criteria to indicate SDR. METHODS: A search was performed in the international network databases according to the following inclusion criteria: (1) design: studies involving longitudinal postoperative follow-up; (2) population: children and adolescents with spastic cerebral palsy; (3) intervention: SDR; (4) control group with different intervention or without intervention; (5) outcome: improvement of motor function, improvement of spasticity and gait performance. RESULTS: A total of six articles were found that met the inclusion criteria and were used in this review. In the studies analyzed, significant improvements were observed in the kinematic gait variable with decreased spasticity in the SDR group. CONCLUSION: SDR decreases spasticity with positive effects on gross motor function and gait of children and adolescents with cerebral palsy, but additional studies are needed to elucidate the efficacy of RDS applied to lower limb muscle groups.

Quedas são comuns entre a população idosa, consideradas como questão de saúde pública, responsáveis por alto grau de morbidade e mortalidade. Isso evidencia a realização de estudos teóricos que qualifiquem o entendimento sobre a relação entre queda e seus fatores de risco; a fisiopatologia dos distúrbios do equilíbrio e da marcha; e a identificação precoce da "queda idiopática" (sem causa evidente). Assim, com base na literatura especializada, o presente estudo apresenta uma visão geral sobre o papel dos sistemas sensoriais responsáveis pela regulação do controle postural, evidenciando as principais estratégias utilizadas por idosos para a manutenção do controle postural e os benefícios proporcionados pela prática regular do exercício físico para a prevenção de quedas de idosos. Como resultado, é apresentado um modelo ilustrativo sobre a sequência de estratégias utilizadas por idosos para reestabelecer a posição ereta em diferentes fases de perturbação postural. Conclui-se que o baixo desempenho da atenção, da memória e de funções executivas eleva a instabilidade postural e reduz a velocidade da marcha, aumentando o risco de quedas. Nesse contexto, a prática regular de exercícios físicos é capaz de reduzir significativamente a taxa de queda de idosos. Aconselham-se a prática de exercícios programados, que agreguem tarefas cognitivas com grau de desafio da instabilidade de moderado a alto, e a prática semanal de duas a três horas.

Common among the older population, falls are considered a public health issue, accounting for high rates of morbidity and mortality. Thus, there is a need for theoretical studies that improve the understanding of the relationship between falls and their risk factors; the pathophysiology of balance and gait disorders; and early identification of "idiopathic fall" (with no apparent cause). Based on the specialized literature, the present study provides an overview of the role of sensory systems responsible for regulating postural control, showing the main strategies that older adults use to maintain postural control and the benefits of regular physical exercise for prevention of falls in older adults. Then, a graphic model describing the sequence of strategies used by older adults to regain an upright stance in different phases of postural perturbation is presented. In conclusion, poor performance of attention, memory, and executive functions increases postural instability and reduces gait speed, thereby raising the risk of falls. In this context, regular physical exercise may significantly reduce the rate of falls in older adults. Planned exercises are recommended and should involve cognitive tasks with moderate-to-high level of instability for two to three hours/week.

Investigation of pain requires measurements of nociceptive sensitivity and other pain-related behaviors. Recent studies have indicated the superiority of gait analysis over traditional evaluations (e.g., skin sensitivity and sciatic function index [SFI]) in detecting subtle improvements and deteriorations in animal models. Here, pain-related gait parameters, whose criteria include (1) alteration in pain models, (2) correlation with nociceptive threshold, and (3) normalization by analgesics, were identified in representative models of neuropathic pain (spared nerve injury: coordination data) and inflammatory pain (intraplantar complete Freund's adjuvant: both coordination and intensity data) in the DigiGait™ and CatWalk™ systems. DigiGait™ had advantages in fixed speed (controlled by treadmill) and dynamic SFI, while CatWalk™ excelled in intrinsic velocity, intensity data, and high-quality 3D images. Insights into the applicability of each system may provide guidance for selecting the appropriate gait imaging system for different animal models and optimization for future pain research.

Introdução: Alguns instrumentos foram desenvolvidos para mensurar o medo de quedas, sendo a Falls Efficacy Scale International (FES-I) o mais conhecido e utilizado. O teste de velocidade da marcha também tem sido bastante utilizado nesse contexto visto que permite reconhecer alterações na marcha e déficits de equilíbrio que estão intimamente ligados ao medo de cair e ao risco de quedas. Objetivo: discutir como o uso de instrumentos de avaliação simples e de baixo custo podem contribuir para verificação do medo de cair e do risco de quedas em idosos institucionalizados. Relato de Experiência: A experiência é fruto do Projeto de Ação Voluntária desenvolvido como parte do evento "EBSERH Solidária" promovido pela Empresa Brasileira de Serviços Hospitalares (EBSERH). O Lar de Idosos "Santa Luiza de Marillac", beneficiado pela ação, é uma instituição de longa permanência localizada no município de Juiz de Fora, Minas Gerais. Durante a ação, a equipe de Fisioterapia avaliou o histórico de quedas no último ano e fatores associados e o medo de cair por meio do questionário FES-I. Foi realizado também o teste de velocidade da marcha para verificar a mobilidade dos idosos e o risco para quedas. Metade dos idosos avaliados referiu ter sofrido pelo menos uma queda no último ano. Pelos escores finais do questionário FES-I (29±8,3 pontos) foi possível perceber que os idosos mostravam-se muito preocupados com a possibilidade de cair. No teste de velocidade da marcha os idosos obtiveram escores intermediários (0,71 ± 0,23 m/s). Após as avaliações os fisioterapeutas orientaram os pacientes conforme as suas necessidades individuais e cada idoso recebeu uma cartilha com orientações específicas para prevenção de quedas. Conclusão: Ações como a mencionada neste trabalho se tornam importantes na identificação do risco de quedas em idosos institucionalizados, podendo assim contribuir para elaboração de estratégias e condutas que visem minimizar a ocorrência deste evento.

Introduction: Some instruments were developed to measure fear of falls, with Falls Efficacy Scale International (FES-I) being the best known and most widely used. The gait speed test has also been widely used in this context since it allows recognizing changes in gait and balance deficits that are closely linked to the fear of falling and the risk of falls. Objective: Discuss how the use of simple and low-cost assessment tools can contribute to the verification of fear of falling and the risk of falls in institutionalized elderly people Experience Report: The experience is the result of the Voluntary Action Project developed as part of the "Solidary EBSERH" event sponsored by the Brazilian Hospital Services Company (EBSERH). The Elderly House "Santa Luiza de Marillac", benefited by the action, is a long-term institution located in the city of Juiz de Fora, Minas Gerais. During the action, the Physiotherapy team evaluated the history of falls in the last year and associated factors and the fear of falling through the FES-I questionnaire. The gait speed test was also performed to verify the mobility of the elderly and the risk for falls. Half of the elderly surveyed said they had suffered at least one drop in the last year. By the final scores of the FES-I questionnaire (29±8.3 points) it was possible to notice that the elderly were very worried about the possibility of falling. In the gait velocity test the elderly had intermediate scores (0.71 ± 0.23 m/s). After the evaluations the physiotherapists guided the patients according to their individual needs and each elderly person received a primer with specific guidelines for fall prevention. Conclusion: Actions such as that mentioned in this study become important in the identification of the risk of falls in institutionalized elderly people, thus contributing to the elaboration of strategies and behaviors that aim to minimize the occurrence of this event.

In this paper, the research has been conducted by the Microsoft kinect for windows v2 for obtaining the walking trajectory data from hemiplegic patients, based on which we achieved automatic identification of the hemiplegic gait and sorted the significance of identified features. First of all, the experimental group and two control groups were set up in the study. The three groups of subjects respectively completed the prescribed standard movements according to the requirements. The walking track data of the subjects were obtained straightaway by Kinect, from which the gait identification features were extracted: the moving range of pace, stride and center of mass (up and down/left and right). Then, the bayesian classification algorithm was utilized to classify the sample set of these features so as to automatically recognize the hemiplegia gait. Finally, the random forest algorithm was used to identify the significance of each feature, providing references for the diagnose of disease by ranking the importance of each feature. This thesis states that the accuracy of classification approach based on bayesian algorithm reaches 96%; the sequence of significance based on the random forest algorithm is step speed, stride, left-right moving distance of the center of mass, and up-down moving distance of the center of mass. The combination of step speed and stride, and the combination of step speed and center of mass moving distance are important reference for analyzing and diagnosing of the hemiplegia gait. The results may provide creative mind and new references for the intelligent diagnosis of hemiplegia gait.
