ABSTRACT

Lower limb ankle exoskeletons have been used to improve walking efficiency and assist the elderly and patients with motor dysfunction in daily activities or rehabilitation training, while the assistance patterns may influence the wearer's lower limb muscle activities and coordination patterns. In this paper, we aim to evaluate the effects of different ankle exoskeleton assistance patterns on wearer's lower limb muscle activities and coordination patterns. A tethered ankle exoskeleton with nine assistance patterns that combined with differenet actuation timing values and torque magnitude levels was used to assist human walking. Lower limb muscle surface electromyography signals were collected from 7 participants walking on a treadmill at a speed of 1.25 m/s. Results showed that the soleus muscle activities were significantly reduced during assisted walking. In one assistance pattern with peak time in 49% of stride and peak torque at 0.7 N·m/kg, the soleus muscle activity was decreased by (38.5 ± 10.8)%. Compared with actuation timing, the assistance torque magnitude had a more significant influence on soleus muscle activity. In all assistance patterns, the eight lower limb muscle activities could be decomposed to five basic muscle synergies. The muscle synergies changed little under assistance with appropriate actuation timing and torque magnitude. Besides, co-contraction indexs of soleus and tibialis anterior, rectus femoris and semitendinosus under exoskeleton assistance were higher than normal walking. Our results are expected to help to understand how healthy wearers adjust their neuromuscular control mechanisms to adapt to different exoskeleton assistance patterns, and provide reference to select appropriate assistance to improve walking efficiency.

ABSTRACT

Abstract Introduction Peripheral vestibular disorders can lead to cognitive deficits and are more common in elderly patients. Objective To evaluate and correlate cognitive, balance and gait aspects in elderly women with chronic peripheral vestibular dizziness, and to compare them with elderly women without vestibular disorders. Methods Twenty-two women presenting peripheral vestibular dizziness episodes for at least six months participated in the study. The individuals were categorized by dizziness severity level: moderate (n = 11) or severe (n = 11). The control group (n = 11) included women showing no vestibulopathy, light-headedness or dizziness. Cognitive assessments and semi-static and dynamic balance assessments were performed with the Balance Master (Neurocom International, Inc., Clackamas, OR), while the Dizziness Handicap Inventory provided a score for the severity of the symptoms. The groups were submitted to statistics of inference and correlation between cognitive, balance and stability variables. Results The group with severe dizziness showed higher sway speed of the center of pressure in the anteroposterior direction, smaller step length, and slower gait than the control group. Regarding the cognitive variables, the group with severe dizziness symptoms presented significant correlations with stability and gait variables. Conclusion The relationship between cognitive aspects, balance and gait was stronger in women with severe dizziness than in those with no vestibulopathy.

ABSTRACT

RESUMO Objetivo Verificar o poder discriminativo e o ponto de corte de diferentes protocolos do teste 4-metre gait speed (4MGS) para identificar capacidade de exercício preservada ou reduzida no teste de caminhada de 6 minutos (TC6min) em pacientes com Doença Pulmonar Obstrutiva Crônica (DPOC); comparar os protocolos do 4MGS; e comparar as características dos indivíduos de acordo com o melhor ponto de corte encontrado. Métodos Foram avaliados 56 pacientes com DPOC. Todos os pacientes foram submetidos à avaliação das características antropométricas, função pulmonar (espirometria) e capacidade funcional de exercício (TC6min e 4 protocolos do 4MGS). No teste 4MGS, os pacientes foram instruídos a caminhar em velocidade usual e máxima em percursos de 4 metros (4MGS 4m - usual e máximo) e 8 metros (4MGS 8m - usual e máximo). Resultados Somente o protocolo 4MGS 4m-máximo foi capaz de identificar capacidade de exercício preservada no TC6min (AUC=0,70) com correlação moderada entre os testes (r=0,52; P<0,0001). O ponto de corte encontrado no 4MGS 4m-máximo foi de 1,27 m/s. Os pacientes com capacidade de exercício preservada (4MGS 4m-máximo ≥1,27m/s) atingiram maior distância percorrida no TC6min em %predito (91±2 vs 76±3; P<0,0001). Nas outras comparações envolvendo gênero, IMC, VEF1%pred e índice GOLD não ocorreram diferenças significantes entre os grupos. Além disso, a concordância de indivíduos classificados com capacidade de exercício preservada e reduzida no TC6min e no 4MGS 4m-máximo foi significante (P=0,008). Conclusão O teste 4MGS 4m-máximo pode ser utilizado para discriminar capacidade de exercício preservada em pacientes com DPOC, e se correlaciona com o TC6min.


ABSTRACT Objective To determine the discriminative capacity and cut-off point of different 4-metre gait speed test (4MGS) protocols in identifying preserved or reduced exercise capacity using the six-minute walk test (6MWT) in patients with Chronic Obstructive Pulmonary Disease (COPD); also, to compare 4MGS protocols and characteristics of individuals according to the best cut-off point. Methods We evaluated fifty-six patients with COPD, all of which were submitted to the assessment of anthropometric characteristics, pulmonary function (spirometry) and functional exercise capacity (6MWT and four protocols of the 4MGS). In the 4MGS test, patients were instructed to walk at normal pace and at maximum speed in a 4 meters course (4MGS 4m - usual pace and at maximum) and 8 meters course (4MGS 8m - usual pace and at maximum). Results Only the 4MGS 4m-maximum protocol was able to identify preserved exercise capacity in the 6MWT (AUC=0.70) with moderate correlation between them (r=0.52; P=0<0.0001). The cut-off point found in the 4MGS 4m-maximum was 1.27 m/s. Patients with preserved exercise capacity (4MGS 4m-maximum ≥1.27m/s) walker greater distances on the 6MWT in %pred (91±2 vs 76±3; P<0.0001). In the other comparisons involving gender, BMI, FEV1% pred and GOLD index there were no significant differences between the groups. In addition, the agreement of individuals classified as preserved and reduced exercise capacity in the 6MWT and 4MGS 4m-maximum was significant (P = 0.008). Conclusion The 4MGS 4m-maximum test can be used to discriminate preserved exercise capacity in patients with COPD and correlates with the 6MWT.

ABSTRACT

The cuboid facet of the navicular bone is an irregular flat surface, present in non-human primates and some human ancestors. In modern humans, it is not always present and it is described as an "occasional finding". To date, there is not enough data about its incidence in ancient and contemporary populations, nor a biomechanical explanation about its presence or absence. The aim of the study was to evaluate the presence of the cuboid facet in ancient and recent populations, its relationship with the dimensions of the midtarsal bones and its role in the biomechanics of the gait. 354 pairs of naviculars and other tarsal bones from historical and contemporary populations from Catalonia, Spain, have been studied. We used nine measurements applied to the talus, navicular, and cuboid to check its relationship with facet presence. To analyze biomechanical parameters of the facet, X-ray cinematography was used in living patients. The results showed that about 50 % of individuals developed this surface without differences about sex or series. We also observed larger sagittal lengths of the talar facet (LSAGTAL) in navicular bones with cuboid facet. No significant differences were found in the bones contact during any of the phases of the gait. After revising its presence in hominins and non-human primates, and its implication in the bipedalism and modern gait, we suggest that cuboid facet might be related with the size of talar facet and the position of the talonavicular joint. However, other factors such as geographical conditions, genetics and stressful activities probably affect its presence too.


La faceta cuboídea del hueso navicular es una carilla plana e irregular, presente en primates no humanos y en algunos de nuestros ancestros. En humanos modernos, no siempre está presente y es descrita como "un hallazgo ocasional" por la bibliografía. Hasta la fecha, no hay suficientes datos acerca de su incidencia en poblaciones antiguas y contemporáneas, ni una explicación biomecánica sobre su presencia o ausencia. El objetivo de nuestro estudio fue evaluar la frecuencia de la faceta cuboídea en poblaciones recientes y antiguas, su relación con las dimensiones de los huesos tarsales y su rol en la biomecánica de la marcha. Fueron estudiados 354 pares de naviculares y otros huesos del tarso provenientes de colecciones osteológicas de Cataluña, España. Aplicamos nueve medidas aplicadas al talus, navicular y cuboides para corroborar su relación con la presencia de la faceta. Para analizar sus parámetros biomecánicos, se empleó X-ray cinematography en pacientes hospitalarios. Los resultados mostraron que alrededor de un 50 % de los individuos desarrollaron esta carilla, sin diferencias entre sexos o series. Además, observamos que la longitud sagital de la faceta talar (LSAGTAL) es mayor en aquellas muestras con faceta cuboídea. No hay diferencias significativas en el contacto de los huesos en ninguna de las fases de la marcha. Después de revisar su presencia en primates no humanos, su implicancia en el bipedismo y en la marcha moderna, sugerimos que la faceta cuboídea podría estar relacionada con el tamaño de la faceta talar y la posición de la articulación talo-navicular. Sin embargo, otros factores como las condiciones geográficas, genética y stress ocupacional también podrían afectar su presencia.

ABSTRACT

ABSTRACT Objective: To present a program of home physical exercises for patients with normal pressure hydrocephalus (NPH) and to evaluate adherence, acceptance and applicability; to verify possible changes in patients with NPH in the home physical exercise program, comparing patients with, and without, a ventriculoperitoneal shunt, regarding gait, quality of life, activities of daily living, static and dynamic balance and its impact on the risks of falling. Methods: This was a controlled clinical trial, with assessments in three moments (0, 10 and 18 weeks) at the home, from October 2015 to November 2017. Fifty-two patients (30 women and 22 men) participated in the study. Results: There was a statistically significant improvement with 10 weeks of home physical exercises for the groups with and without ventriculoperitoneal shunt, respectively, in the sub-items: activities of daily living p = 0.032*, p = 0.003*; static balance p < 0.001*, p < 0.001*; functional capacity p < 0.001*, p = 0.027*; and dynamic balance and gait p = 0.009*, p < 0.001*. There was no statistically significant difference for the subitems: quality of life p = 0.695, p = 1.000; and NPH grading scale p = 0.695, p = 1.000, respectively. Conclusion: The developed program of home physical exercise was easily applied and there was good acceptance by most patients with NPH included in the research. There was a statistically significant improvement with the 10 weeks of home physical exercises in the sub-items: activities of daily living, static balance and functional capacity, for both groups. In the sub-item dynamic balance and gait, there was a statistically significant improvement for both groups, but with a higher score for the group with a ventriculoperitoneal shunt. There was no statistically significant difference for the sub-items: quality of life, NPH grading scale and risk of falls, based on the Berg scale.

ABSTRACT

RESUMO O objetivo do estudo foi verificar se existem diferenças na força muscular dos membros inferiores (MMII) e na habilidade de locomoção de indivíduos pós-acidente vascular encefálico (AVE) crônico, classificados como deambuladores comunitários ou não comunitários. Foi realizado um estudo transversal em 60 indivíduos pós-AVE crônico, divididos em deambuladores comunitários (n=33) e não comunitários (n=27) pela velocidade de marcha. A força muscular de sete grupos musculares bilaterais de MMII foi avaliada por meio do teste do esfigmomanômetro modificado e habilidade de locomoção pelo ABILOCO. Estatísticas descritivas foram utilizadas para caracterizar a amostra, e o teste t de Student para amostras independentes, a fim de comparar os dois grupos de indivíduos pós-AVE. Observou-se que os deambuladores comunitários apresentaram maiores valores de força muscular para a maioria dos grupos musculares de MMII (−0,973≥t≥−3,189; p≤0,04), e na habilidade de locomoção (t=−2,841; p=0,006). Os indivíduos pós-AVE crônico deambuladores comunitários possuem maior força muscular de MMII e mais habilidade de locomoção em comparação aos deambuladores não comunitários. Sugere-se que a avaliação fisioterapêutica de indivíduos pós-AVE inclua, além da mensuração da força muscular de MMII e seu tratamento, a mensuração da percepção da habilidade de locomoção, para análises da evolução do paciente e da eficácia da conduta terapêutica.


RESUMEN El objetivo del estudio fue verificar si existen diferencias en la fuerza muscular de los miembros inferiores (MMII) y en la habilidad de locomoción de individuos post-accidente cerebrovascular encefálico (ACV) crónico, clasificados como deambuladores comunitarios o no comunitarios. Se realizó un estudio transversal en 60 individuos post-ACV crónico, divididos en deambuladores comunitarios (n = 33) y no comunitarios (n = 27) por la velocidad de marcha. La fuerza muscular de siete grupos musculares bilaterales de MMII fue evaluada por medio de la prueba del esfigmomanómetro modificado, y la habilidad de locomoción por el ABILOCO. Las estadísticas descriptivas se utilizaron para caracterizar la muestra, y la prueba t de Student para muestras independientes con el fin de comparar los dos grupos de sujetos post-ACV. Se observó que los deambuladores comunitarios presentaron mayores valores de fuerza muscular para la mayoría de los grupos musculares de MMII (−0,973≥t≥−3,189; p≤0,04), y en la habilidad de locomoción (t=−2,841; p=0,006). Los individuos post-ACV crónico deambuladores comunitarios poseen mayor fuerza muscular de MMII y más habilidad de locomoción en comparación a los deambuladores no comunitarios. Se sugiere que la evaluación fisioterapéutica de individuos post-ACV incluya, además de la medición de la fuerza muscular de MMII y su tratamiento, la medición de la percepción de la habilidad de locomoción, para análisis de la evolución del paciente y de la eficacia de la conducta terapéutica.


ABSTRACT The objective of this study was to verify if there are differences in the lower-limb muscle strength (LL) and in the locomotion ability among post-stroke patients classified as community or non-community ambulators. A cross-sectional study was conducted in 60 post-chronic stroke subjects, divided into community (n=33) and non-community (n=27) ambulators by gait speed. The muscle strength of seven bilateral muscle groups of LL was evaluated through the modified sphygmomanometer test and locomotion ability through ABILOCO. Descriptive statistics were used to characterize the sample, and Student's t-test was used for independent samples to compare the two groups of post-stroke individuals. We observed that community ambulators had higher values of muscle strength for most muscle groups of LL (−0.973≥t≥3.189; p≤0.04), and in the locomotion ability (t=−2.841; p=0.006). Community ambulators showed higher LL muscle strength and better locomotion ability compared with non-community ambulators. Physiotherapeutic evaluation of post-stroke individuals should include, besides the measurement of LL muscle strength and its treatment, the measurement of the perception of locomotion ability to analyze the evolution of the patient and the efficacy of the therapeutic behavior.

ABSTRACT

A marcha das crianças com paralisia cerebral (PC) tem sido alvo de intervenções conservadoras como a Equoterapia. Entretanto, seus efeitos têm sido pouco sistematizados na literatura. Objetivo: Analisar a evidência da efetividade da Equoterapia na marcha de crianças com PC comparada às terapias conservadoras não invasivas de ensaios clínicos. Método: Trata-se de uma revisão sistemática com busca nas bases de dados Cinahl, Cochrane, Embase, Google Scholar, Lilacs, Lisa (ProQuest), PEDro, PsycINFO (APA), Pubmed e Scopus, sem fltros. Foram incluídos ensaios clínicos que compararam Equoterapia e terapias convencionais (terapias conservadoras não invasivas) versus terapias convencionais, que avaliaram parâmetros da marcha em crianças com diagnóstico de PC com idade ≤ 12 anos. Os estudos foram avaliados quanto à qualidade metodológica pela escala Physiotherapy Evidence Database Scale. Resultados: Dentre os 668 estudos identificados, seis ensaios clínicos foram selecionados. Destes, a amostra total foi de 283 crianças, sendo 151 crianças alocadas no grupo experimental (GE) (hipoterapia + terapia convencional) e 132 crianças, no grupo controle (GC) (terapia convencional). Quatro estudos apresentaram elevada qualidade metodológica e dois estudos, baixa qualidade. Em relação à melhora dos parâmetros da marcha, GE e GC melhoraram, no entanto o GE apresentou significante melhora na análise da dimensão e (andar-pular-correr) da medida da função motora grossa, redução da assimetria muscular durante a deambulação e aumento da velocidade da marcha. Conclusão: A revisão sistemática sugere que o tratamento com associação de hipoterapia e terapia convencional promove melhora da marcha de crianças com PC.


Gait in cerebral palsy (CP) has been the target of conservative interventions as hippotherapy. However, the effects of this therapy on the promotion and functional adaptation of gait have been little systematized in the literature. Objective: To analyze the evidence of the effectiveness of hippotherapy in the gait of children with CP comparing to noninvasive conservative therapies of clinical trials. Methods: A systematic review of clinical trials was performed with search indatabases Cinahl, Cochrane, Embase, Google Scholar, Lilacs, Lisa (ProQuest), PEDro, PsycINFO (APA), Pubmed and Scopus), with no flters. It was included clinical trials comparing hippotherapy plus conventional therapy (non-invasive conservative therapies) versus conventional therapy that assessed gait parameters in children with CP diagnosis and age ≤ 12 years old. The studies were examined as methodological quality by the Physiotherapy Evidence Database Scale. Results: Of the 668 studies identifed, six trials were selected. Of these, the total sample consisted of 283 children (151 children were allocated to the experimental group (hippotherapy) and 132 children, in the control group (conventional therapies). Four studies presented high methodological quality and two studies, low quality. Regarding the improvement of gait parameters, experimental group and control group improved, however, the experimental group presented signifcant improvement in the analysis of the E dimension (walk-jump-run) of the gross motor function measure instrument, reduction of muscular asymmetry during walking and increase in walking speed. Conclusion: The systematic review, suggests that the treatment with association of hippotherapy and conventional therapy promotes improvement of gait of children with CP.

Mais de 50% da população mundial encontra-se na faixa de sobrepeso e de obesidade, caracterizando uma epidemia global e, com isso, atingindo mulheres em idade reprodutiva.Quando da associação de obesidade e gravidez, esse risco pode estar amplificado, acentuando alterações do equilíbrio e postura, ampliando a taxa de acidentes por queda.(AU)


More than 50% of the world population is in the overweight and obesity zone, characterizing a global epidemic and with these reaching women of reproductive age. When associated with obesity and pregnancy, this risk may be amplified, accentuating alterations on balance and posture, increasing the rate of accidents by fall.(AU)

ABSTRACT

OBJECTIVES: Loss of muscle mass and/or physical performance, a condition commonly known as sarcopenia, is prevalent in chronic obstructive pulmonary disease (COPD) and is associated with adverse outcomes. The aim of this study was to investigate the association between functional performance and sarcopenia in COPD patients classified by disease severity according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. METHODS: The study was a cross-sectional observational and the sample size consisted of 35 COPD patients (69.24±1.54 years, 20 men). Physical performance was assessed with the timed up-and-go (TUG) test. Sarcopenia was assessed according to the European Working Group on Sarcopenia in Older People criteria. RESULTS: The frequency of sarcopenia was 20% and was more prevalent among individuals classified with greater disease severity, GOLD III, n=4 patients (23%) and GOLD IV, n=3 patients (27%), p=0.83. The mean time to complete the TUG test was 11.66±4.78 s. Binary logistic regression revealed an association between the TUG test and sarcopenia adjusted by disease severity (OR=1.55, 95% CI: 1.03-8.23, p=0.04). CONCLUSION: Our findings showed that worse performance in the TUG test leads to a substantial increase in the chance of COPD patients presenting sarcopenia.

ABSTRACT

The present study aimed to analyze age-related changes to motor coordination, balance, spinal cord oxidative biomarkers in 3-, 6-, 18-, 24-, and 30-month-old rats. The effects of low-intensity exercise on these parameters were also analyzed in 6-, 18-, and 24-month-old rats. Body weight, blood glucose, total cholesterol, and high-density lipoprotein (HDL) cholesterol were assessed for all rats. The soleus muscle weight/body weight ratio was used to estimate skeletal muscle mass loss. Body weight increased until 24 months; only 30-month-old rats exhibited decreased blood glucose and increased total cholesterol and HDL cholesterol. The soleus muscle weight/body weight ratio increased until 18 months, followed by a small decrease in old rats. Exercise did not change any of these parameters. Stride length and step length increased from adult to middle age, but decreased at old age. Stride width increased while the sciatic functional index decreased in old rats. Performance in the balance beam test declined with age. While gait did not change, balance improved after exercise. Aging increased superoxide anion generation, hydrogen peroxide levels, total antioxidant capacity, and superoxide dismutase activity while total thiol decreased and lipid hydroperoxides did not change. Exercise did not significantly change this scenario. Thus, aging increased oxidative stress in the spinal cord, which may be associated with age-induced changes in gait and balance. Regular low-intensity exercise is a good alternative for improving age-induced changes in balance, while beneficial effects on gait and spinal cord oxidative biomarkers cannot be ruled out because of the small number of rats investigated (n=5 or 6/group).

ABSTRACT

Abstract Introduction: Calcium is vital for the functioning of the inner ear hair cells as well as for the neurotransmitter release that triggers the generation of a nerve impulse. A reduction in calcium level could therefore impair the peripheric vestibular functioning. However, the outcome of balance assessment has rarely been explored in cases with osteopenia and osteoporosis, the medical conditions associated with reduction in calcium levels. Objective: The present study aimed to investigate the impact of osteopenia and osteoporosis on the outcomes of behavioural and objective vestibular assessment tests. Methods: The study included 12 individuals each in the healthy control group and osteopenia group, and 11 individuals were included in the osteoporosis group. The groups were divided based on the findings of bone mineral density. All the participants underwent behavioural tests (Fukuda stepping, tandem gait and subjective visual vertical) and objective assessment using cervical and ocular vestibular evoked myogenic potentials. Results: A significantly higher proportion of the individuals in the two clinical groups' demonstrated abnormal results on the behavioural balance assessment tests (p < 0.05) than the control group. However, there was no significant difference in latencies or amplitude of cervical vestibular evoked myogenic potential and oVEMP between the groups. The proportion of individuals with absence of ocular vestibular evoked myogenic potential was significantly higher in the osteoporosis group than the other two groups (p < 0.05). Conclusion: The findings of the present study confirm the presence of balance-related deficits in individuals with osteopenia and osteoporosis. Hence the clinical evaluations should include balance assessment as a mandatory aspect of the overall audiological assessment of individuals with osteopenia and osteoporosis.


Resumo: Introdução: O cálcio é vital para o funcionamento das células ciliadas, assim como para a liberação dos neurotransmissores que desencadeiam um impulso nervoso. Uma redução nos níveis de cálcio poderia, portanto, prejudicar o funcionamento vestibular periférico. No entanto, a avaliação do equilíbrio tem sido raramente explorada em casos de osteopenia e osteoporose, condições médicas associadas à redução dos níveis de cálcio. Objetivo: O presente estudo teve como objetivo investigar o impacto da osteopenia e da osteoporose nos resultados dos testes de avaliação comportamental e vestibular objetiva. Método: O estudo incluiu 12 indivíduos nos grupos controle e grupo de osteopenia e 11 indivíduos no grupo da osteoporose. Os grupos foram divididos com base nos achados da densidade mineral óssea. Todos os participantes foram submetidos a testes comportamentais (Prova dos Passos de Fukuda, Marcha em tandem e Vertical Visual Subjetiva) e à avaliação objetiva com o uso de potenciais evocados miogênicos vestibulares cervical e ocular (cVEMP e oVEMP). Resultados: Uma proporção significativamente maior de indivíduos nos dois grupos com condições clínicas mostrou resultados anormais nos testes de avaliação comportamental e do equilíbrio (p < 0,05) do que o grupo controle. Embora não tenha havido diferença significativa nas latências ou na amplitude de cVEMP e oVEMP entre os grupos, a proporção de indivíduos com ausência de oVEMP foi significativamente maior no grupo da osteoporose do que nos outros dois grupos (p < 0,05). Conclusão: Os resultados do presente estudo demonstram a presença de déficits de equilíbrio em indivíduos com osteopenia e osteoporose. Assim, as avaliações clínicas gerais e audiológicas de indivíduos com osteopenia e osteoporose deveriam incluir a avaliação do equilíbrio como um aspecto obrigatório.

ABSTRACT

ABSTRACT To identify the factors affecting the use of physiotherapy services among individuals with Parkinson's disease (PD) living in Brazil. Methods: Overall, 479 individuals with idiopathic PD, of both sexes, at any stage of the Hoehn & Yahr (HY) scale, and from seven capital cities in Brazil were recruited from 2014 to 2016. Multivariate logistic regression was the main statistical tool. For the construction of the logistic model, the association of the dependent variable "physiotherapy" with the independent sociodemographic/economic and clinical variables: age, education, family income, time of PD since onset, HY, the activities of daily living and motor subscales of the Unified Parkinson's Disease Rating Scale, cognitive aspects, depressive symptoms, fear of falling, freezing gait, history of falls, physical activity level, gait speed, walking performance and balance, were verified. Results: The 479 individuals had an average age of 65.2 ± 11.0 years, 88% were in the HY I-III stages and 43.4% were under physiotherapy treatment. The analysis identified two determinant variables related to the use of the physiotherapy service: level of education (OR = 1.24) and walking performance (OR = 0.82). Decreased walking performance and a higher educational level increased the use of a physiotherapy service in individuals with PD living in Brazil. Conclusions: The present study shows that individuals with PD, residents from different regions of Brazil, have limited access to physiotherapy services. In addition, the Brazilian Public Health Care System, as well as local programs, need to target PD individuals with a low educational level to improve their access to physiotherapy services. Goals should aim towards the development of physical exercise programs to improve the patients' functional performance for a longer period.


RESUMO Descrever a utilização do serviço de fisioterapia e identificar os fatores que determinam o uso desse serviço entre indivíduos com doença de Parkinson (DP) que vivem no Brasil. Métodos: No total, 479 indivíduos com DP idiopática, de ambos os sexos, em qualquer estágio da escala de Hoehn & Yahr (HY) e de sete capitais do Brasil foram recrutados durante 2014 a 2016. A análise de regressão logística multivariada foi a principal ferramenta de análise estatística. Para a construção do modelo logístico foi investigada a associação da variável dependente "fisioterapia" com variáveis independentes sociodemográficas, econômicas e clínicas: idade, educação, renda familiar, tempo de DP desde o início, HY, domínio motor e atividade de vida diária da Unified Parkinson´s Disease Rating Scale, aspectos cognitivos, sintomas depressivos, medo de queda, congelamento marcha, história de quedas, nível de atividade física, velocidade de marcha, capacidade de caminhar e equilíbrio. Resultados: 479 indivíduos apresentaram média de 65,2 ± 11,0 anos, 88% tiveram HY = I-III e 43,4% faziam fisioterapia para a DP. A análise identificou duas principais variáveis determinantes do uso da fisioterapia: educação (OR = 1,24) e capacidade de caminhada (OR = 0,82). A diminuição da capacidade de caminhar e maior nível educacional aumentam o uso da fisioterapia em indivíduos com doença de Parkinson vivendo no Brasil. Conclusões: O presente estudo mostra que indivíduos com DP, residentes de diferentes regiões do Brasil, têm acesso limitado aos serviços de fisioterapia. Além disso, o Sistema Brasileiro de Saúde Pública, bem como os programas locais, precisam atingir pessoas de DP com baixo nível educacional para melhorar seu acesso aos serviços de fisioterapia. Os objetivos devem ser para o desenvolvimento de programas de exercícios físicos para melhorar o desempenho funcional dos pacientes por um período mais longo.

ABSTRACT

ABSTRACT Motor and non-motor manifestations are common and disabling features of hereditary spastic paraplegia (HSP). Botulinum toxin type A (Btx-A) is considered effective for spasticity and may improve gait in these patients. Little is known about the effects of Btx-A on non-motor symptoms in HSP patients. Objective To assess the efficacy of Btx-A on motor and non-motor manifestations in HSP patients. Methods Thirty-three adult patients with a clinical and molecular diagnosis of HSP were evaluated before and after Btx-A injections. Results Mean age was 41.7 ± 13.6 years and there were 18 women. Most patients had a pure phenotype and SPG4 was the most frequent genotype. The Btx-A injections resulted in a decrease in spasticity at the adductor muscles, and no other motor measure was significantly modified. In contrast, fatigue scores were significantly reduced after Btx-A injections. Conclusion Btx-A injections resulted in no significant functional motor improvement for HSP, but fatigue improved after treatment.


RESUMO Manifestações motoras e não motoras são comuns e incapacitantes nas paraparesias espásticas hereditárias (PEH). Toxina botulínica do tipo A (TB-A) é considerada eficaz no tratamento da espasticidade e pode melhorar a marcha nesses pacientes. Pouco se sabe sobre os efeitos da TB-A sobre sintomas não-motores. Objetivo avaliar a eficácia da TB-A sobre manifestações motoras e não-motoras nas PEH. Método trinta e três pacientes adultos com PEH foram avaliados antes e depois das aplicações de TB-A. Resultados A média de idade foi 41,7 ± 13,6 anos e havia 18 mulheres. A maioria dos pacientes portava a forma pura e o genótipo mais comum foi SPG4. Houve diminuição da espasticidade dos músculos adutores da coxa sem melhora da marcha. A pontuação da fadiga reduziu após as injeções. Conclusão As aplicações de TB-A não melhoraram a marcha nos pacientes mas a redução da fadiga foi significativa após o tratamento.

ABSTRACT

Abstract Objective To evaluate the correlation between physical examination data concerning hip rotation and tibial torsion with transverse plane kinematics in children with cerebral palsy; and to determine which time points and events of the gait cycle present higher correlation with physical examination findings. Methods A total of 195 children with cerebral palsy seen at two gait laboratories from 2008 and 2016 were included in this study. Physical examination measurements included internal hip rotation, external hip rotation, mid-point hip rotation and the transmalleolar axis angle. Six kinematic parameters were selected for each segment to assess hip rotation and shank-based foot rotation. Correlations between physical examination and kinematic measures were analyzed by Spearman correlation coefficients, and a significance level of 5% was considered. Results Comparing physical examination measurements of hip rotation and hip kinematics, we found moderate to strong correlations for all variables (p<0.001). The highest coefficients were seen between the mid-point hip rotation on physical examination and hip rotation kinematics (rho range: 0.48-0.61). Moderate correlations were also found between the transmalleolar axis angle measurement on physical examination and foot rotation kinematics (rho range 0.44-0.56; p<0.001). Conclusion These findings may have clinical implications in the assessment and management of transverse plane gait deviations in children with cerebral palsy.


Resumo Objetivo Avaliar a correlação entre dados do exame físico relativos à rotação do quadril e torção tibial com a cinemática do plano transverso em crianças com paralisia cerebral; e determinar quais pontos no tempo e eventos do ciclo de marcha apresentam maior correlação com achados do exame físico. Métodos Um total de 195 crianças com paralisia cerebral vistas em dois laboratórios de marcha, de 2008 a 2016, foi incluído neste estudo. As medidas do exame físico incluíram rotação interna do quadril, rotação externa do quadril, ponto médio da rotação do quadril e ângulo do eixo transmaleolar. Foram selecionados seis parâmetros cinemáticos para cada segmento, para avaliar a rotação do quadril e a do pé em relação à perna durante a marcha. As correlações entre exame físico e medidas cinemáticas foram analisadas por coeficientes de correlação de Spearman, e considerou-se um nível de significância de 5%. Resultados Comparando as medidas da rotação do quadril e da cinemática do quadril, encontramos correlações moderadas a fortes para todas as variáveis (p<0,001). Os coeficientes mais altos foram observados entre o ponto médio da rotação do quadril no exame físico e a rotação do quadril na cinemática (rho range: 0,48-0,61). Correlações moderadas também foram encontradas entre a medição do ângulo do eixo transmaleolar no exame físico e a rotação do pé em relação à perna na cinemática (faixa rho: 0,44-0,56; p<0,001). Conclusão Estes achados podem ter implicações clínicas na avaliação e no tratamento de desvios da marcha do plano transverso em crianças com paralisia cerebral.

ABSTRACT

ABSTRACT Objective: To analyze which abnormalities in body composition (obesity, sarcopenia or sarcopenic obesity) are related to reduced mobility in older people aged 80 years and older. Methods: The sample included 116 subjects aged 80 years and older. The body composition was measured using dual-energy X-ray absorptiometry (DXA) and mobility was assessed by motor tests. The χ2 test was used to analyze the proportion of older people with sarcopenia, obesity and sarcopenic obesity based on sex as well as to indicate an association between obesity, sarcopenia, sarcopenic obesity and mobility. Binary logistic regression, adjusted for the variables (sex and osteoarticular diseases), was used to express the magnitude of these associations. One-way analysis of variance was used to compare the mobility of four groups (Normal, Obesity, Sarcopenia and Sarcopenic Obesity). Results: The Sarcopenia Group had lower performance in the lower limbs strength test and in sum of two tests compared with Obesity and Normal Groups. Older people with sarcopenia had higher chance of reduced mobility (OR: 3.44; 95%CI: 1.12-10.52). Conclusion: Older people aged 80 years and older with sarcopenia have more chance for reduction in mobility.


RESUMO Objetivo: Analisar quais agravos na composição corporal (obesidade, sarcopenia ou obesidade sarcopênica) estão relacionados à redução da mobilidade em idosos com 80 anos ou mais. Métodos: A amostra foi constituída por 116 sujeitos com idade igual ou superior a 80 anos. A composição corporal foi mensurada pela técnica de absorciometria de raios X de dupla energia (DXA), e a mobilidade foi avaliada por testes motores. O teste χ2foi utilizado para analisar a proporção de idosos com sarcopenia, obesidade e obesidade sarcopênica, de acordo com o sexo, bem como para indicar a associação entre obesidade, sarcopenia, obesidade sarcopênica e mobilidade. A análise de regressão logística binária, ajustada pelas variáveis (sexo e doenças osteoarticulares), foi utilizada para expressar a magnitude das associações. A análise de variância foi usada para comparar a mobilidade entre os quatro grupos (Normal, Obesidade, Sarcopenia e Obesidade Sarcopênica). Resultados: O Grupo Sarcopenia apresentou menor desempenho no teste de força de membros inferiores e na soma dos dois testes, comparado aos Grupos Obesidade e Normal. Idosos com sarcopenia apresentaram maior chance de redução da mobilidade (OR: 3,44; IC95%: 1,12-10,52). Conclusão: Idosos com idade igual ou superior a 80 anos com sarcopenia têm mais chance de redução da mobilidade.

ABSTRACT

Resumen: Introducción: La rehabilitación cardiovascular ha demostrado tener efectos beneficiosos en pacientes con antecedentes de patología coronaria. Objetivos: Identificar los factores que determinan el resultado de un programa de rehabilitación cardiovascular (PRC) aplicado a pacientes coronarios revascularizados. Métodos: 67 pacientes sometidos a cirugía de bypass o angioplastia fueron evaluados en su capacidad funcional mediante el test de marcha de 6 minutos (TM) al inicio y al completar el programa de rehabilitación cardiovascular. La distancia recorrida en el test de marcha fue correlacionada con la edad, capacidad funcional previa al PRC, tiempo en completar el pro-grama, tiempo que media entre la intervención y el inicio del programa, duración del programa y tipo de revascularización. Además, se comparó el incremento de la capacidad funcional entre los pacientes que fueron derivados a 36 sesiones con los referidos a solo 12. Resultados: 67 pacientes cumplieron los criterios para evaluación del PRC. Globalmente, se observó una mejoría de 12% (511,4 a 573,4 m) en la distancia del TM (p<0.001)). El mayor beneficio, en términos de distancia en el TM se obtuvo al efectuar un programa con más sesiones (36 vs 12) con valores de 20% y 8%, respectivamente (p<0.002). El poder terminar el PRC de 36 sesiones más rápidamente (entre 10 y 13 semanas vs entre 14 y 24 semanas se asoció a una mayor incremente en el TM con valores de 19% vs 10%, respectivamente (p<0,003). El incremento en el TM no difirió entre 3 grupos de edad (desde 49 a 85 años); en el tiempo que transcurre entre la intervención y el inicio del PRC (antes vs después de la 8a semana post revascularización), al tipo de revascularización a la que fue sometido el paciente (cirugía o angioplastía) y a la capacidad funcional previa que estos presentan al inicio del PRC. Conclusión: El PRC es efectivo en mejorar significativamente la capacidad funcional de pacientes revascularizados, especialmente cuando el número de sesiones del programa es mayor y cuando se realiza con una frecuencia de al menos 3 veces por semana. El PRC es igualmente efectivo en pacientes enviados a rehabilitación en forma más precoz, como también lo es en sujetos más añosos. Estos efectos fueron independientes del tipo de revascularización.


Abstracts: Introduction : Background: Cardiovascular Rehabilitation Programs (CRP) have been shown to produce be-neficial effects in patients with coronary artery disease. Aim: to identify factors associated to CRP success in patients who underwent myocardial revascularization Methods: 67 patients who underwent coronary artery bypass surgery (CABG) or percutaneous coronary artery angioplasty (PTCA) were evaluated for functional capacity by means of a standard 6 min walking test (6mWT), before and after completion of the CRP. Distance covered during the test was correlated with age, prior functional class, time employed to complete CRP, time from coronary intervention and CRP initiation, CRP duration and type of revascularization. In addition, patients referred for a 36 sessions CRP were compared to those referred to only 12 sessions. Results: 67 patients met inclusion criteria. Overall, there was a 12% increase (511,4 to 573,4 m) in 6mWT distance (p<0.001). The greatest benefit was obtained with the 36 session CRP as compared to a 12 session CRP (20 vs 8% (p<0.002). Also, completion of a 36 session CRP between 10 and 13 weeks compared to 14 to 24 weeks revealed a greater benefit in the former group (19% vs 10%, respectively (p<0.003). There was no difference in 6minWT distance in 3 groups of age (extending from 49 to 85 years-old); In addition, time from intervention to initiation of CRP (before vs after 8 weeks), type of revascularization or functional capacity at the beginning of CRP showed any difference in 6mWT distance. Conclusion: CRP is a highly effective intervention to improve functional capacity in patients following myocardial revascularization, more so when more sessions are employed and when at least 3 sessions per week are implemented. The program is equally effective in patients starting CRP early after revascularization, and benefit is independent from patient age.

ABSTRACT

Abstract The purpose of this study was to determine the relationship between peak cadence indicators and body mass index (BMI) and body fat percentage (BF%)-defined weight status in children. The sample comprised 485 Brazilian children. Minute-by-minute step data from accelerometry were rank ordered for each day to identify the peak 1-minute, 30-minute and 60-minute cadence values. Data were described by BMI-defined and bioelectrical impedance-determined BF% weight status. BMI-defined normal weight children had higher peak 1-minute (115.5 versus 110.6 and 106.6 steps/min), 30-minute (81.0 versus 77.5 and 74.0 steps/min) and 60-minute cadence (67.1 versus 63.4 and 60.7 steps/min) than overweight and obese children (p<.0001), respectively. Defined using %BF, normal weight children had higher peak 1-minute (114.5 versus 106.1 steps/min), 30-minute (80.4 versus 73.1 steps/min) and 60-minute cadence (66.5 versus 59.9 steps/min) than obese children (p<.0001). Similar relationships were observed in boys; however, only peak 1- minute cadence differed significantly across BMI and %BF-defined weight status categories in girls. Peak cadence indicators were negatively associated with BMI and BF% in these schoolchildren and significantly higher among normal weight compared to overweight or obese children.


Resumo O objetivo do estudo foi determinar a relação entre indicadores de pico de cadência com índice de massa corporal (IMC) e percentual de gordura corporal (% GC) definidos pelo estado de peso corporal de crianças. Participaram 485 crianças brasileiras. Minutos de acelerometria foram ranqueados para identificar os valores de picos de cadência de 1, 30 e 60 minutos. O estado de peso corporal foi apresentado pelo IMC e %GC, avaliados pela bioimpedância elétrica. No IMC, crianças eutróficas apresentaram maior pico de cadência de 1 minuto (115,5 versus 110,6 e 106,6 passos/min), 30 minutos (81,0 versus 77,5 e 74,0 passos/min) e 60 minutos (67,1 versus 63,4 e 60,7 passos/min) do que aqueles com excesso de peso e obesidade (p < 0,001). Na %GC, crianças eutróficas apresentaram maior pico de cadência de 1 minuto (114,5 versus 106,1 passos/min), 30 minutos (80,4 versus 73,1 passos/min) e 60 minutos (66,5 versus 59,9 passos/min) do que as obesas. Relações semelhantes foram observadas nos meninos; no entanto, apenas o pico de cadência de 1 minuto foi significativamente diferente nas categorias do estado de peso corporal definido pelo IMC e %GC nas meninas. Indicadores de pico de cadência foram negativamente associados com IMC e %GC e maior nos eutróficos do que naqueles com excesso de peso e obesidade.
