Contudo, o conhecimento pleno das suas repercuss?es fisiol?gicas e dos par?metros que possam trazer maior seguran?a quanto ? sua prescri??o; em especial os efeitos a curto e m?dio prazo (24 horas ap?s o exerc?cio) sobre a recupera??o do exerc?cio, necessitam ser esclarecidos. O objetivo do presente trabalho ? avaliar a repercuss?o de uma sess?o de exerc?cio aer?bico cont?nuo e intervalado no controle auton?mico card?aco imediato e em m?dio prazo (24 horas), atrav?s da avalia??o da variabilidade da frequ?ncia card?aca (VFC). Trata-se de um ensaio cl?nico randomizado do tipo crossover onde indiv?duos jovens saud?veis e com baixo n?vel de atividade f?sica tiveram a VFC de 24 horas mensurada atrav?s de frequenc?metro e aceler?metro port?til (eMotion HRV 3D, Kuopio, Finl?ndia) antes e ap?s sess?o de exerc?cio aer?bio cont?nuo (60-70% FCmax, 21min.) e intervalado (ciclo 1 min. a 80-90% FCmax, 2 min. a 50-60% FCmax, dura??o 21 min.). A VFC foi avaliada nos dom?nio tempo e frequ?ncia e o balan?o simpatovagal determinado pela raz?o LF/HF. Avalia??o n?o linear foi calculada pela entropia de Shannon. O dados demonstraram retardo na recupera??o imediata da frequ?ncia card?aca p?s exerc?cio e menor FC 24 horas comparados a valores pr? interven??o, principalmente no exerc?cio intervalado. Houve tend?ncia ? maior predom?nio e valores de ?ndices representantes da estimula??o simp?tica durante o dia no grupo de exerc?cio intervalado; contudo, sem signific?ncia estat?stica. O resultados do estudo auxiliam no esclarecimento das repercuss?es do exerc?cio intervalado nas 24 horas que sucedem a interven??o permitindo par?metros para prescri??o e futura avalia??o de grupos de indiv?duos com patologias metab?licas e cardiovasculares. / The high-intensity interval exercise has been described as an option for increasing physical activity and its use also being suggested in the therapeutic management of many conditions such as diabetes mellitus and heart failure. However, the knowledge of its physiological effects and parameters that can assure greater safety for interval exercise prescription; especially its effect on short- and medium-term (24 hours after exercise) exercise recovery, need to be clarified. This study objective was to evaluate the effect of continuous and interval aerobic exercise on the cardiac autonomic control immediate and medium term (24 hours), by assessing heart rate variability (HRV). The present study is a randomized crossover clinical trial in which healthy young individuals with low level of physical activity had the VFC 24 hours measured by a heart rate sensor and portable accelerometer (3D eMotion HRV, Kuopio, Finland) before and after continuous aerobic exercise (60-70% HR max, 21 min.) and interval exercise (cycle 1 min. 80-90% HR max, 2 min. at 50-60% HR max, duration 21 min.). HRV was measured in the time and frequency domain and the sympathovagal balance determined by the ratio LF / HF. Nonlinear evaluation was calculated by Shannon entropy. The data demonstrated delayed heart rate recovery immediate after exercise and lower HR after 24 hours compared to pre intervention values, especially in the interval exercise group. There was a tendency to higher predominance and representatives index values of sympathetic stimulation during the day in interval exercise group; however, without statistical significance. The study results help to clarify the effects of interval exercise on the 24 hours following interval exercise, setting parameters for prescription and for further evaluation of groups with metabolic and cardiovascular diseases.

Palavras-chave Diabetes Mellitus. Fototerapia. Exerc?cio. Tend?o de Aquiles. Cicatriza??o / Diabetes Mellitus (DM ) is a complex disease that requires continuous medical care for the reduction of risk factors in addition to glycemic control. The typical hyperglycemia of this disease produces glycosylation of proteins and so the consequence is the accumulation of glycosylation final products in various human tissues, among them, the tendon. The aerobic exercise (AE) and the low level laser therapy (LLLT) have been used to treat tendinopathies in individuals with or without DM. Objective: The aim of this study was to watch the effect of the LLLT and the AE, in association, in partial tenotomy of the tissue repair of the Achilles tendon (AT) of diabetic rats. Methods: 91 animals were utilized and divided in to the following groups: control group (GC), injured control group (GCL), diabetic group (GD), diabetic group LLLT (GD ? TLBI), diabetic group trained (GD - EX) and diabetic group trained laser (GD-EX+TLBI). The animals were submitted to intervention with AE, using a protocol with a progressive increase of time (12 to 60 min) and speed of (4 to 9 m/min), and the LLLT (660 nm laser, 10mW, 4 J/cm?, single point for 16 seconds, three times for week). It was analyzed morphological, biomechanical and molecular characteristics. For data showing normal distribution was used one-way ANOVA test and post hoc Tukey and data without normal distribution was used Mann Whitney test and post hoc Dunn's. It was accepted p <0.05 for statistical significance Results: The biomechanical tests indicated major improvement in the GC and GD-EX+TLBI groups when compared with the diabetic groups in the following variables: maximum load, strain, absorbed energy, stress, cross section area, elastic modulus and energy density (p<0.05). The analysis through molecular biology indicated that the association of aerobic exercise and LLLT generated an increase of the collagen I gene expression and modulated the expression of the MMP2 and MMP9 (p<0.05). No observed any major improvement in the morphological variable studied. Conclusion: the LLLT associated with aerobic exercise promotes and increase of the mechanical properties, in the control of collagen I gene expression and of the MMP2 and MMP9 of the diabetic rats.

Regarding the motor function of the arm (5 trials), the estimated effect for the therapy was not significant. However, when considering the hand function estimating the effect was favorable to the group that conducted the AO, in short (mean difference = 6.93, 95% CI 1.48 to 12.39; P = 0.01) and long-term (mean difference = 7.57; 95% CI 1.34 the 13.80; p = 0.02). Unable to perform the analysis for functional dependency. The studies showed a low or uncertain risk of bias, but the quality of evidence the body was considered low and very low quality. Authors? conclusions: AO was effective in improving hand function of stroke patients. Despite the low quality evidence that the use of OA in clinical practice should not be discouraged. RCT new studies should be conducted with greater methodological rigor and larger samples, covering important outcomes such as functional dependence for ADLs.

In the musculoskeletal system, a main change is the decreased muscle strength, that in the lower extremity, compromises the ability to respond quickly with enough strength to prevent falls, causing alterations in postural balance. Currently, many researchers have study the human frailty, defined as a multifactorial syndrome, with excess of vulnerability to stressors, reducing ability in maintaining or regulating homeostasis. Its characteristics are directly related to physical function. Aim: To analyze muscle performance and postural balance in frail and pre-frail elderly women, and to compare them according with the frailty phenotypes criteria proposed by Fried 2001. Method: 39 frail elderly women living in the community, aged 65 years and older, were assessed muscle performance of lower extremity using isokinetic dynamometer and postural balance using Berg s balance scale and computerized baropodometry. Results: There was significant difference in plantar flexor, knee flexor and knee extensor strength, in anteroposterior (AP) oscillation with eyes open and on Berg s scores between groups. A weak correlation was observed between strength and balance. Conclusion: The results suggest that the frail elderly present worse muscle performance in lower extremity and worse postural balance compared to the pre-frail elderly. There were correlations between muscle performance and balance impairments in these elderly, but several variables are also involved in maintaining postural balance / Introdu??o: o envelhecimento humano ? um processo fisiol?gico que gera altera??es nos diversos sistemas do organismo. No sistema musculoesquel?tico, a principal mudan?a gerada ? o decr?scimo da for?a muscular, que nos membros inferiores, compromete a habilidade de responder rapidamente e com for?a suficiente para prevenir quedas, levando a altera??es no equil?brio postural. Atualmente, muitos p esquisadores t?m estudado a fragilidade humana, que ? definida como uma s?ndrome de car?ter multifatorial, em que ocorre um excesso de vulnerabilidade aos estressores, com redu??o na habilidade de manter ou regular a homeostasia. Estas caracter?sticas est?o diretamente relacionadas a fun??o f?sica. Objetivo: analisar par?metros do desempenho muscular e equil?brio postural entre idosas fr?geis e pr?-fr?geis, e compar?-los com os crit?rios do fen?tipo de fragilidade propostos por Fried et al 2001. Metodologia: 39 idosas fr?geis comunit?rias, acima de 65 anos, foram avaliadas quanto aos par?metros do desempenho muscular do membro inferior atrav?s do dinam?metro isocin?tico, e do equil?brio postural na Escala de Equil?brio de Berg e na Baropodometria Computadorizada.

Initially held a subjective evaluation of balance through a questionnaire (Berg Balance Scale-BBS) then the kinematic gait analysis was realized on a treadmill first, without inclination and then, with inclination of 10%, using the motion system analysis Qualisys System. Data analysis was done using BioStat 5.0 attributing significance level of 5%. Normality of data was verified using D'Agostino test and later was applied paired t-test to compare data in two experimental conditions. Results: There was a statistically significant difference in the spatiotemporal variables: reduction in the cadence (from 108.92 ? 39.07 to 99.11 ? 27.51, p <0.04), increase in cycle time (from 1.24 ? 0.27 to 1.36 ? 0.34, p = 0.03 ) and increase in time to take stock (from 0.77 ? 0.15 to 0.82 ? 0.18, p <0.001). Angular variables that showed statistically significant increasing were: the hip in the initial contact (12.23 ? 4.63 to 18.49 ? 5.17, p <0.0001) and max. flexion in balance (12.96?4:32 to 19.50 ? 4.51, p <0.0001 ), knee in the initial contact (15.59 to ? 6.71 to 21.63 ? 6.48, p <0.0001), the ankle in the initial contact (-2.79 ? 9.8 to 2.25 ? 8.79, p <0.0001), max dorsiflexion in stance (4.41 ? 10.07 to 7.13 ? 11.58, p <0.0009), maximum plantar flexion in the pre-assessment of the ankle joint (increase of -6.33 ? 8.77 to -2.69 ? 8.62, p <0.0004).Conclusions: The inclination acts in a positive way for angular and spatiotemporal features gait of children with Down syndrome, demonstrating possible benefit of using this surface in the gait rehabilitation of children with Down Syndrome / Contextualiza??o: A s?ndrome de Down (SD) ? uma altera??o gen?tica caracterizada por ser uma encefalopatia cong?nita n?o progressiva. As crian?as com SD apresentam hipotonia muscular e atraso no desenvolvimento neuropsicomotor que dificultam a aquisi??o da marcha para estas crian?as. Objetivo: Analisar os efeitos da inclina??o da esteira na marcha de crian?as com SD. Metodologia: Foram avaliados 23 sujeitos ( 9 do g?nero feminino e 14 do g?nero masculino), com m?dia de idade de 8,43 ?2,25 anos, com capacidade de deambular classificada em n?vel 5 de acordo com a Categoria de Deambula??o Funcional (FAC Functional Ambulatory Category). Inicialmente realizou-se avalia??o subjetiva de equil?brio atrav?s de question?rio (Escala de Equil?brio de Berg- BBS) em seguida, a an?lise cinem?tica da marcha em esteira el?trica sem inclina??o e com inclina??o de 10%, utilizando o sistema de an?lise do movimento Qualisys System. Para an?lise dos dados foi utilizado o programa Bioestat 5.0 atribuindo-se n?vel de signific?ncia de 5%. A normalidade dos dados foi verificada pelo teste D`Agostino e posteriormente foi aplicado o teste t-pareado para comparar os dados nas duas condi??es experimentais. Resultados: Observou-se diferen?a significante estatisticamente nas vari?veis espa?o-temporais: redu??o na cad?ncia ( de 108,92 ? 39,07 para 99,11 ? 27,51, p< 0,04) , aumento no tempo do ciclo (de 1,24 ? 0,27 para 1,36 ? 0,34, p=0,03) e aumento no tempo de balan?o (de 0,77 ? 0,15 para 0,82 ? 0,18, p< 0,001) . As vari?veis angulares que demonstraram aumento estatisticamente significante foram: quadril no contato inicial (de 12,23+4,63 para 18,49+ 5,17, p<0,0001) e m?x. flex?o no balan?o (de 12,96 ? 4,32 para 19,50 ? 4,51, p<0,0001); joelho no contato inicial (de 15,59 ? 6,71 para 21,63 ? 6,48, p< 0,0001); e tornozelo no contato inicial (de 2,79 ? 9,8 para 2,25 ? 8,79, p<0,0001), m?x. dorsiflex?o no apoio (de 4,41 ?10,07 para 7,13 ? 11,58, p<0,0009), m?x. flex?o plantar no pr?-balan?o (de 6,33 ? 8,77 para 2,69 ? 8,62, p<0,0004). Conclus?es: A inclina??o atua de forma positiva nas caracter?sticas angulares e espa?o-temporais da marcha de crian?as com S?ndrome de Down, demonstrando poss?vel benef?cio da utiliza??o deste tipo de superf?cie na reabilita??o da marcha desta popula??o

But their findings are not well known when combined with biofeedback. OBJETIVE: The purpose of this study was to evaluate the immediate effects of biofeedback, visual and auditory, combined with treadmill training with BWS on on walking functions of hemiplegic subjects. METHODS: We conducted a clinical trial, randomized controlled trial with 30 subjects in the chronic stage of stroke, underwent treadmill training with BWS (control), combined with visual biofeedback, given by the monitor of the treadmill through the symbolic appearance of feet as the subject gave the step; or auditory biofeedback, using a metronome with a frequency of 115% of the cadence of the individual. The subjects were evaluated by kinematics, and the data obtained by the Motion Analysis System Qualisys. To assess differences between groups and within each group after training was applied to ANOVA 3 x 2 repeated measures. RESULTS: There were no statistical differences between groups in any variable spatio-temporal and angular motion, but within each group there was an increase in walking speed and stride length after the training. The group of visual biofeedback increased the stance period and reduced the swing period and reason of symmetry, and the group auditory biofeedback reduced the double stance period. The range of motion of the knee and ankle and the plantar flexion increased in the visual biofeedback group. CONCLUSION: There are no differences between the immediate effects of gait training on a treadmill with BWS performed with and without visual or auditory biofeedback. However, the visual biofeedback can promote changes in a larger number of variables spatiotemporal and angular gait / INTRODU??O: O treino de marcha em esteira com suporte parcial de peso (SPP) tem mostrado diversos benef?cios para o paciente ap?s um acidente vascular encef?lico (AVE), tendo-se, no entanto, pouco conhecimento dos seus resultados associados ao est?mulo por biofeedback. OBJETIVO: Verificar os efeitos imediatos do biofeedback, visual e auditivo, associado ao treino de marcha em esteira com SPP sobre a marcha de sujeitos hemipar?ticos. M?TODOS: Foi realizado um ensaio cl?nico, randomizado e controlado com 30 sujeitos no est?gio cr?nico do AVE, submetidos ao treino de marcha em esteira com SPP (controle), podendo ser associado ao biofeedback visual (experimental I), dado pelo monitor da esteira por meio do aparecimento de p?s simb?licos ? medida que o sujeito dava o passo, ou ao biofeedback auditivo (experimental II), usando-se um metr?nomo em uma frequ?ncia de 115% da cad?ncia do indiv?duo. Os sujeitos foram avaliados por cinemetria, sendo os dados obtidos pelo Sistema de An?lise de Movimento Qualisys. Para avaliar as diferen?as entre os grupos e dentro de cada grupo ap?s o treinamento, foi aplicada o teste param?trico ANOVA 3 x 2 de medidas repetidas. RESULTADOS: N?o houve diferen?as estat?sticas entre os grupos em nenhuma das vari?veis espa?o-temporais e angulares da marcha, mas dentro de cada grupo houve um aumento da velocidade da marcha e do comprimento do passo ap?s o treinamento. O grupo do biofeedback visual aumentou o tempo de apoio e reduziu o tempo de balan?o e sua raz?o de simetria; e o grupo do biofeedback auditivo reduziu o tempo de duplo suporte. Houve um aumento da ADM do joelho e tornozelo e da flex?o plantar no grupo biofeedback visual. CONCLUS?O: N?o h? diferen?as entre os efeitos imediatos do treino de marcha em esteira com SPP realizado sem e com biofeedback visual ou auditivo. No entanto, o biofeedback visual pode promover altera??es em um maior n?mero de vari?veis espa?o-temporais e angulares da marcha

Objective: To validate the Legan?s Cognitive Test (Prueba Cognitive de Legan?s) (PCL) for cognitive screening in low educated elderly Brazilians. Methods: The study sample was composed of 59 elderly residents from the city of Santa Cruz, Brazil with low schooling levels. Reliability was analyzed with a 2-day interval between assessments, and concurrent validity was assessed using the Mini Mental State Examination (MMSE). Results: According to the PCL, the prevalence of dementia was 11.8%. The scale items showed a moderate to strong correlation between domains (p <0.01), and inter-rater reliability exhibited ICC = 0.81, 95% CI (0.72-0.88). Factor analysis resulted in two factors: memory and orientation. Interscale agreement was considered poor (k = - 0.02), supporting the hypothesis of an educational impact on final MMSE scores. Conclusion: The results suggest that PCL has acceptable levels of reliability for use in low educated elderly Brazilians / Introdu??o: As escalas de rastreio cognitivo s?o ferramentas importantes para detec??o precoce da dem?ncia, gerando a possibilidade de desenvolvimento de medidas que retardem esse processo e auxiliem no manejo da doen?a. Objetivo: Validar a Prova Cognitiva de Legan?s (PCL) para rastreio cognitivo em idosos brasileiros com baixo n?vel de escolaridade. M?todos: Utilizou-se uma amostra de 59 idosos residentes no munic?pio de Santa Cruz-RN, com baixo n?vel educacional. A confiabilidade foi analisada com intervalo de dois dias entre as avalia??es, e a validade concorrente foi avaliada atrav?s do Mini Exame do Estado Mental (MEEM). Resultados: De acordo com a PCL a preval?ncia de dem?ncia foi de 11,8%. Os itens da escala apresentaram correla??o de moderada ? forte entre os dom?nios (p<0,01), e a confiabilidade inter-examinador apresentou um ICC=0.81, IC 95% (0.72-0.88). A an?lise fatorial agrupou dois fatores interpretados como mem?ria e orienta??o. A an?lise de concord?ncia entre as escalas mostrou um kappa ruim, refor?ando a hip?tese de influ?ncia de escolaridade no escore final obtido no MEEM. Conclus?o: Os resultados sugerem que a PCL possui n?veis de confiabilidade aceit?veis para utiliza??o em idosos brasileiros com baixa escolaridade, minimizando o vi?s de escolaridade presente na maioria das escalas de avalia??o cognitiva

Frailty is a multidimensional syndrome that increases susceptibility to diseases and disability. However it may be possible to prevent or postpone frailty if is identified early. Our objective is to analyze SPPB s ability in screening for frailty a community-dwelling young elderly from cities with distinct socioeconomic conditions. Methods: Data were originated from community dwelling adults (65-74 years old) in Canada (Saint Bruno; n = 60) and Brazil (Santa Cruz; n = 64). SPPB was used to assess physical performance. Frailty was defined as the presence of &#8805; 3 of these criteria: weight loss, exhaustion, weakness, mobility limitation and low physical activity. One point was given for each criterion met, totalizing a frailty score ranged from 0 to 5. The Linear Regression and Receiver Operating Characteristics analyses were performed to evaluate the SPPB s screening ability. Results: Mean age was 69.48, 10.0% of the Saint Bruno s sample and 28.1% of Santa Cruz s were frail (p = 0.001), the SPPB score means were 9.6 and 8.5 respectively (p = 0.01). SPPB correlated with the frailty score (R2 = 0.33), with better results for Saint Bruno. A cutoff of 9 in SPPB had good sensitivity and specificity in discriminating frail from non frail in Saint Bruno (AUC = 0.81) but showed fair results in Santa Cruz (AUC = 0.61). Conclusion: The SPPB has moderate ability in predicting frailty among older adult s population, and is an useful test to identify people with good functionality and low frailty when SPPB scores are &#8805;9 / Introdu??o: A SPPB proporciona informa??o sobre a fun??o f?sica e ? preditora de eventos adversos de sa?de em idosos. A fragilidade ? uma s?ndrome multidimensional que aumenta a susceptibilidade ? doen?as e incapacidade. Entretanto, pode ser poss?vel prevenir ou postergar a fragilidade se ela for identificada precocemente. O objetivo desse estudo foi analisar a habilidade da SPPB em predizer a fragilidade em uma popula??o de idosos jovens residentes na comunidade de cidades com condi??es socioecon?micas distintas. M?todos: Os dados foram extra?dos da comunidade de idosos (65-74 anos) do Canad? (Saint Bruno; n = 60) e do Brasil (Santa Cruz; n = 64). A SPPB foi usada para avaliar o desempenho f?sico. A fragilidade foi definida como a presen?a de &#8805; 3 dos crit?rios: perda de peso, exaust?o, fraqueza, limita??o da mobilidade e baixo n?vel de atividade f?sica. Um ponto foi dado para cada crit?rio encontrado, totalizando um escore da fragilidade que variou de 0 a 5. As an?lises de Regress?o Linear e ROC foram realizadas para avaliar a capacidade preditiva da SPPB. Resultados: A m?dia de idade foi de 69,48 anos, 10% da amostra de Saint Bruno e 28,1% da amostra de Santa Cruz eram fr?geis (p = 0,001), as m?dias de escores da SPPB foram de 9,6 e 8,5 respectivamente (p = 0,01). A SPPB correlacionou-se ao escore da fragilidade (R2 = 0,33), com melhores resultados para Saint Bruno. Um ponto de corte de 9 na SPPB teve boa sensitividade e especificidade em discriminar fr?geis de n?o fr?geis em Saint Bruno (AUC = 0,81), mas mostrou piores resultados em Santa Cruz (AUC = 0,61). Conclus?o: A SPPB tem moderada habilidade em predizer a fragilidade entre a popula??o de idosos e ? um teste ?til para identificar pessoas com boa funcionalidade e baixa fragilidade quando os escores da SPPB s?o &#8805; 9
